Dear Dr. Sigal:
I want to thank you for responding to my emails over the last few months. I know I can be candid and straight to the point sometimes. By reopening the compassionate Drug Use (ipilimumab) you and your company gave the Melanoma Patients “The Last Chance of HOPE”. You don’t know how much this means to us. If we haven’t passed the “Lethal Tumor Burden” we still have a chance of survival. I believe you have done your company justice and showed your compassion. My faith in the Company’s Ethics has been restored.

Now we need to prove to the world that this drug may be one of the most important discoveries in the last twenty years of Cancer. By taking the “Brakes off the Immune System” we can harness our own immune system to battle cancer. Granted we may have to use the drug in combinatorial therapy to rid the host of the cancer once and for all. I hope you and your company can collaborate together with all the major players in this exciting field of Oncology. See it took millions of years for our immune system to evolve, so why do we think that one drug can do it all. We need to approach the Beast arm to arm, to block all the pathways so it can’t escape. This can only be done by using one’s own immune system.

Can you imagine working out a protocol that will vaccinate the patient with the patients own tumor–specific antigen? And Ipilimumab (Anti-CTLA-4 Blockade) is at the center of this revolutionary therapy/protocol. Please if you get a chance, listen to some of the lectures and symposiums from the like of Dr. James Allison, Dr. Jedd Wolchok, Dr. Antonio Ribas, Dr. Jeffery Weber, Dr Keith Flaherty and others. You will be amazed at their accomplishments in the clinical setting. But they need more. They need access to the entire drug arsenal that is available across companies. We now know that timing and dose concentration plays a major roll in setting up an immune response. There are feedback loops. It is like dominos. You have this elaborate step-up. It may take weeks to build. Once you set it in motion, the chips begin to fall. There are different pathways, cytokines, T-cells, receptors, etc that need to be taken into account get the right immune response. This immune response can only be generated if you have all the keys to unlock the response. We need yours and other Pharmaceuticals to work together for the good of the cancer patients. We need to take down all the red tape which also includes the FDA.

“Our Life depends on it.”

Thanks again.
Sincerely,
Jim Breitfeller

The Missing Link in T-cell activation using a Vaccine, "The Danger Signal" may be due to an enzyme called IDO

The Missing Link in T-cell activation using a Vaccine, "The Danger Signal" may be due to an enzyme called IDO

As I research why some patients respond to therapies i.e. vaccination and other immunotherapy and others don’t, I ask WHY? In my quest to get the answer or answers, I came across a paper called “Marked Differences in Human Melanoma Antigen-Specific T Cell Responsiveness after Vaccination Using a Functional Microarray”.

Daniel S. Chen1,2#, Yoav Soen3#, Tor B. Stuge4, Peter P. Lee4, Jeffrey S. Weber5, Patrick O. Brown2,3, Mark M. Davis2,6* 1 Department of Internal Medicine/Division of Oncology, Stanford University, Stanford, California, United States of America, 2 Howard Hughes Medical Institute, Stanford University, Stanford, California, United States of America, 3 Department of Biochemistry, Stanford University, Stanford, California, United States of America, 4 Department of Medicine, Stanford University, Stanford, California, United States of America, 5 Norris Cancer Center, University of Southern California, Los Angeles, California, United States of America, 6 Department of Microbiology and Immunology, Stanford University, Stanford, California, United States of America

This is what I was looking for! It may hold the answer or could possibly point me in the right direction. In the paper I came across a diagram that peaked my interest. It was a comparison between responders and non-responders.






We concluded from these studies that IL-1 and perhaps IL-6 play a critical role in the differentiation and expansion of Th17 cells. Yoshihiro Miyahara et al
 
IL-6 controls Th17 immunity by inhibiting the conversion of naive CD4+ T cells into Foxp3+ regulatory T cells.

Using in vitro and in vivo approaches, we determined that under neutral conditions, simultaneous activation of Tregs and naive CD4+ conventional T cells in the presence of APCs resulted in conversion of Tregs into IL-17–producing cells, and endogenous IL-1β was mandatory in this process according to Vassiliki A. Boussiotis et al. “IL-1β–Mediated Signals Preferentially Drive Conversion of Regulatory T Cells but Not Conventional T Cells into IL-17–Producing Cells”

IL-6 protects CD4 T cells from cell death but also inhibits the suppressive effect of T regs.

“Thus, the addition of IL-6 to the tumor microenvironment skews the balance toward Th17 cells in a murine model of pancreatic cancer. The delayed tumor growth and improved survival suggests that induction of Th17 in the tumor microenvironment produces an antitumor effect.” David C. Linehan  et al

They were looking at the cytokines secreted after the vaccine was given. When I saw what the cytokines were, I knew I was on the right track. These cytokines help in the differentiation of the CD4+ T-cells. What a find!!



Naïve CD4 T cells in the presence of   TGF-b and IL-2 and others differentiate into Tregs.

TGF-b accelerates the CTLA-4 expression by stimulated CD4+ CD25- T-cells

TGF-b requires CTLA-4 early after T-cell activation to induce FoxP expression generating CD4+ CD25+ Treg  Regulatory cells.

The Th-17 cells produce IL-17. .IL-17 induces the production of many other cytokines (such as IL-6, G-CSF, GM-CSF, IL-1β, TGF-β, TNF-α)

 


So what was the non-responder missing, IL-6.  With the missing IL-6, they weren’t able to produce Th-17 that secreted IL-17.

While TGF-β is a critical differentiation factor for Treg cells, IL6 completely inhibits the generation of Treg cells induced by TGF-β. Instead, IL6 and TGF-β together induce the differentiation of pathogenic Th17 cells. With IL-6 missing in the microenvironment, Treg Cells flourish.

If the CD4 + T cells differentiate into TH2 cells that produce IL-4, the other cells inhibited to produce IL-6. IL-4 was found to inhibit TNF-α and IL-1β by activated monocytes almost 100 %. The Secretion of IL-6 was decreased by approximately 80 % in the presences of IL-4 Cytokine. TE Velde et al 1990

 They were missing “The Danger Signal”.

Friendly inflammation “The Danger Signal”


Most of the time you have no notion of the microbial life-and-death struggle being waged within your body. At other times, though, you are acutely aware of the exact location of the battleground, thanks to the unmistakable signs of inflammation — heat, pain, redness, and swelling. Inflammation, the buildup of fluid and cells at the point of infection/cancer, is put into motion by cytokines — proteins that are released into the blood by the innate immune system when it encounters germs. Cytokines function like police dispatchers. They signal there's a problem, which activates the immune system's highway patrol force: the circulating lymphocytes of the adaptive immune system. These lymphocytes cruise the highways of the blood vessels and lymphatic system. In response to the chemical signal from the cytokines, increased blood flow rushes these circulating cells to the trouble spot.

 “The CD8+ T-cell-mediated Immune Response to Eradicate the Tumors


 “Three major events must occur to induce CD8+ T cell–mediated, tumor-protective immunity against syngeneic melanoma. First, the T-cell receptor must be triggered by a (or multiple) self antigen–derived peptide MHC class I complex . Therefore, this event depends entirely on appropriate antigen presentation, which is most efficiently provided by mature dendritic cells. Peripherally tolerant or “ignorant” self-reactive T-cell clones, once properly activated, may serve as tumor-specific effector T cells .Second, simultaneously with T-cell receptor triggering, a distinct second costimulatory signal must be delivered, mediated by IL-2, B7-1, or B7-2, which engage IL-2 receptors and CD28 on the surface of the T cell, respectively. A source of these cofactors for effective CD8+ T-cell stimulation can be provided by CD4+ T cells that release critical amounts of IL-2, or by mature dendritic cells that display an increased level of B7-1/B7-2 costimulatory molecules on their cell surfaces. Third, inflammatory cytokines, including IL-1, IL-6, IL-12, IL-17 and IFN-γ provide a third signal that acts directly on T cells, referred to as the “danger signal”. This signal was found to optimally activate TH1 differentiation and lead to clonal expansion of T cells.

 
 


 
The responder was able to produce inflammatory cytokines, including IL-1, IL-6, IL-12, IL-17 and IFN-γ provides a third signal that acts directly on T cells, referred to as the “danger signal”. This signal was found to optimally activate TH1 differentiation and lead to clonal expansion of T cells and invoke a robust immune response to the Melanoma Cancer.
 
 


Conclusion:  Based on my observation, the cytokine that ties this “Danger Signal” to the immune system is IL-6.

  • IL-6 protects CD4 T cells from cell death but also inhibits the suppressive effect of Tregs.
  • IL-6 controls Th17 immunity by inhibiting the conversion of naive CD4+ T cells into Foxp3+ regulatory T cells.
So what is causing the lack of IL-6 in the non-responders? The IDO enzyme. This enzyme catalyzes the degradation of the essential amino acid L-tryptophan to N-formylkynurenine.

IDO enzyme degrades tryptophan and through the GCN2 kinase pathway inhibits the transcription of IL-6. Without the transcription of IL-6, the IL-6 cytokine cannot be produced leading to the T-cell differentialtion toward the T Regulatory cell instead of the TH17 phenotype.




My guess is the tumor induced enzyme called IDO may the Missing Link to intiating an immune response.IDO produced by Tumor cells significantly inhibited interleukin (IL-2) expression and proliferative response in T-cells and increased apoptosis (death) of T-cells. Tryptophan depletion is known to halt cell cycle progression by triggering the antiproliferative GCN2 pathway in lymphocytes.

Also, IDO is upregulated in antigen-presenting dendritic cells (DC) by autocrine IFN-γ released as a result of Treg cell–induced CTLA-4/B7-dependent cell-cell signaling.

It is well established that IDO expression by APCs or tumors can inhibit immune responses.

Tryptophan depletion by IDO-expressing tumors is a common mechanism of immune evasion inducing regulatory T cells and inhibiting effector T cells.

So adding IDO inhibitor to a combinatorial therapy like Yervoy for melanoma cancer should see a synergist response.

Immunotherapy.. The Magic Bullet.. The Breakthrough Therapy.. the Paradigm Shift.. The Future

I wrote about this as the "Magic bullet" back in 2009.Great insight in where immunotherapy is heading in the future.



When you combine anti-CD47 therapy with checkpoint therapy (anti-PD1 and or anti-CTLA4/Yervoy), you involve the innate and the adoptive immune system to eradicate cancer (Melanoma)
 I would like to see combinatorial therapy with checkpoint inhibitors like yervoy/anti-CTLA-4 & anti-PD-1along with anti-CD47 to eliminate the "don't eat me" signal, so the macrophages can get involved with the tumor elimination.

Pearls of Wisdom: Melanoma ..Jim Breitfeller

Pearls of Wisdom: Melanoma
Reviewed by Douglas Johnson, MD and Jeffrey Sosman, MD

This entry was posted on Tuesday, January 8, 2013 at 6:33 pm Management of Advanced Disease


Metastatic melanoma historically has had a very poor prognosis with a median survival of 6-9 months. However, recent advances in molecularly targeted therapy as well as immune based therapies have provided several effective treatment options for oncologists and their patients. In 2012 there are several important issues to consider in the management of patients with newly diagnosed advanced melanoma.


Advanced Stage III/Stage IV resectable disease

• In patients with advanced stage III disease or oligometastatic disease, consultation with an experienced surgical oncologist is warranted, as patients can experience long term survival with an aggressive surgical approach. Despite the advances in systemic therapy, surgical resection is still our preferred option in most of these clinical situations. One series of 64 patients showed a >30% four year survival in patients who had completely resected metastatic disease.1

•Another option we have offered is a short course of systemic therapy for 6-12 months prior to surgery with the intent to improve the chance that rapid recurrence of disease does not occur and to define the tumor’s responsiveness to the treatment.
•Patients should be considered for clinical trials in the adjuvant setting. Studies are ongoing to assess whether ipilimumab or vemurafenib is effective in preventing recurrences in high risk patients. For stage IV (M1) disease after complete surgical treatment there is no standard of care adjuvant treatment.


•Interferon, the current standard of care for fully resected stage IIb-III disease, is also an option in the adjuvant setting.
Molecular Testing

•All patients with metastatic disease should undergo testing for BRAF V600 mutations given the availability of targeted therapy for this mutation. This should include testing for the alternate V600 mutations that make up about 20% of BRAF mutations at this codon and appear sensitive to the BRAF inhibitors such as vemurafenib and dabrafenib.2 Patients with advanced local or regional disease can also be considered for testing since there are a number of clinical trials either recently or soon to be activated with BRAF inhibitor based therapy in BRAF V600 mutated melanoma at stage IIC-IIIC. Additionally, results will be available on progression so that therapy can be rapidly initiated if needed.
•Evaluation of several KIT mutations should also be considered in at least specific clinically defined subsets of patients. Though KIT mutations are present in only ~2% of all melanomas, acral (feet and hands) and mucosal melanomas harbor KIT mutations in 15-20% of cases. KIT mutations are sensitive to imatinib in about 25% of the cases based on limited numbers of patients.3
•NRAS mutations are also present in 15-20% of patients and though no targeted therapies are yet established as standard for this subset, there are a number of studies underway specifically targeting this mutation. Furthermore, the NRAS mutation may confer a poor prognosis to the melanoma.4


Standard therapies for metastatic disease

Vemurafenib
Vemurafenib is a BRAF inhibitor approved for patients with metastatic melanoma with BRAF V600 mutations (40-50%). In phase III trial data, objective tumor shrinkage was seen in well over 50% of patients, and clinical benefit seen in nearly all patients during the initial few weeks of administration. Median progression-free survival was 6.9 months (compared to 1.6 months with dacarbazine).5 Some important points regarding vemurafenib therapy:
•Responses are often rapid and dramatic. If patients with mutated BRAF V600 melanoma are highly symptomatic, vemurafenib would be our first line therapy in nearly all such patients.
•Patients will inevitably progress or relapse, often within the first year. Strategies to prevent or delay resistance are being pursued. In fact, recently the addition of a MEK inhibitor, trametinib, demonstrated an ability to improve the frequency of objective responses and the duration of progression-free survival in those melanoma patients receiving dabrafenib (BRAF inhibitor).
•Vemurafenib has clinical activity in patients with brain metastases in small series. Prospective phase II trials are pending completion. Trials with dabrafenib have also demonstrated frequent clinical benefits in such patients.6
•Secondary squamous cell carcinomas are common in BRAF inhibitor trials (10-25%).7 Suspicious lesions should be biopsied. Additionally, secondary melanomas and CMML have been reported in the presence of vemurafenib; almost certainly the drug has played a role to accelerate the appearance and growth of these tumors.
Ipilimumab (Yervoy)


Ipilimumab is an antibody to CTLA-4 and functions as an immune checkpoint inhibitor. This “removes the brakes” on the immune system which decreases immune tolerance to the tumor but may also cause autoimmune toxicities. In phase III trials, overall survival was increased compared to a vaccine in previously treated patients (10 mos vs. 6.4 mos), and in combination with dacarbazine compared with dacarbazine alone in the first line setting (11.2 vs. 9.1 months).8,9 Some important points to consider:
•Tumor burden on exam or on imaging may transiently worsen even in patients destined to respond. We do not repeat imaging until after 12 weeks of therapy unless the patient develops concerning new or progressive symptoms.
•Since even responding patients may have tumor growth or slow shrinkage, we are hesitant to use this therapy in highly symptomatic patients, especially if there are reasonable alternatives.
•Autoimmune side effects may be severe. Colitis, hepatitis, dermatitis, neuropathy, and endocrinopathies are the most common toxicities.
•Patients should be monitored closely for colitis. Concerning symptoms (diarrhea, melena/hematochezia, abdominal pain) require rapid evaluation. Though Imodium is appropriate for mild diarrhea (grade I), grade II toxicities or worse require prompt initiation of steroids. Colonoscopy should be performed to confirm the diagnosis in patients with severe colitis. Bowel perforation and death have been reported in extreme cases almost always when initial therapy is delayed.
•Headaches, with or without vision changes and fatigue may represent hypophysitis. Evaluation of TSH, cortisol, and testosterone, and brain MRI can aid in this diagnosis.
•We monitor TSH, cortisol, and liver enzymes at every visit.

•Other rare immune mediated side effects such as Guillan Barre syndrome, myasthenia gravis, sarcoidosis, and hemophilia have also been described.
Interleukin-2 (IL-2)


IL-2 has been used for many years in treating metastatic melanoma. It is associated with 6% durable remission rate (cures) and 15-20% overall response rate.10 Its use is limited to centers familiar with the associated severe side effects. Some points to consider when treating or referring patients:


•Therapy is limited to healthy patients usually under 70 years of age with adequate cardiac, pulmonary, renal, hepatic, and hematopoietic organ function and well controlled brain metastases. Nearly all patients experience treatment associated hypotension, multi-organ dysfunction, and vascular leak syndrome

•Though newer agents exist, IL-2 has the most long term data showing durable remissions in the minority of patients. We still consider this therapy in interested, eligible patients.
•Advantages of using IL-2 compared to ipilimumab include longer duration of use and more rapid assessments of benefit (8 weeks vs. 12+ weeks). Advantages to ipilimumab include outpatient use, generally less severe side effects, and possibly higher rates of durable remissions.



Cytotoxic chemotherapy

•Dacarbazine, temazolamide, and carboplatin/paclitaxel occasionally benefit patients with metastatic disease.
•No consistent survival benefit has been demonstrated with cytotoxic chemotherapy. Response rates are typically in the 5-10% range.
•We use chemotherapy only in patients who are not eligible for other therapies.
Which therapy should be chosen as first line therapy in patients with BRAF V600E/K mutations?
•This decision should be individualized. No head to head comparisons have been done with immunotherapy in the form of ipilimumab or interleukin-2 therapy. BRAF inhibitors are associated with high response rates but inevitable progression, while immune therapies have low objective response rates but durable remissions in a minority of patients.

•In patients with rapidly progressive or highly symptomatic disease, we typically use vemurafenib. In patients with asymptomatic disease, we favor immune based therapies for interested patients. An intergroup randomized cross over trial will address this issue, where half the patients start with vemurafenib and the other half on ipilimumab.



Promising Therapies


Therapy for metastatic melanoma is rapidly evolving. Many clinical trials are ongoing, and patients should be encouraged to participate in clinical trials for first line therapy or at progression if treated with standard therapy options. Some therapies that are likely to be approved are listed below.
•BRAF/MEK inhibitor combination therapies: Dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor) have both shown benefit individually over dacarbazine in phase III trials in patients with BRAF mutant metastatic melanoma. However, interest lies especially in combination therapy to delay resistance and disease progression. In a randomized phase II trial, combination therapy was associated with an improved objective response rate (54% vs 76%) and progression free survival compared to dabrafenib alone (9.4mo vs. 5.8mo).11 Additionally, the incidence of squamous cell carcinomas was dramatically decreased with combination therapy. Trials are ongoing comparing this combination with vemurafenib in untreated patients with BRAF mutations. An additional trial is evaluating vemurafenib in combination with GDC-0973, a MEK inhibitor.



•Anti-PD-1 therapy:

Several newer checkpoint inhibitors block the interaction between PD-1 (expressed on T-cells) and PD-L1 (expressed on tumor) which activates the immune system, hopefully in a tumor specific manner. A phase I trial with nivolumab (anti-PD1 BMS) data shows a 31% response rate with fewer autoimmune side effects than ipilimumab.12 Pneumonitis was described in several patients. Trials are ongoing in patients who have progressed on ipilimumab. Early reports of another anti-PD1, MK-3475 also show a remarkable response rate in patients either following Ipilimumab or de novo in the 40-50% response range.

•Anti-PD-1 + Yervoy therapy:

By using both Checkpoint inhibitors, you and block two pathways that the melanoma can't use for immunosuppression. This allows the activated T-cells to go unchecked and keeps the immune response switch on. This clinical trial is ongoing at Sloan Kettering, and Yale. Rumor has it that they are seeing high response rates.

ASCO 2013.. The comming out party for Combination Therapy!!! Yervoy + Anti-PD-1 ..Melanoma. Jim Breitfeller

ASCO 2012 was PD-1’s debutant ball, but we may have found a partner (Yervoy) at this Year’s 2013 Ball and may be only a few years away from its coronation (FDA’s approval) as a stand alone or combinatorial therapy. I believe that ASCO 2013 will be the coming out party for combination therapy of Anti-PD-1 + Yervoy.

br />
Using this combination blocks two checkpoint pathways on the T-Cells leaving it activated to proliferate and destroy the cancer.


If you add Yervoy & Anti-PD-1 to the therapy you have a better chance to activate the CD4 and CD8 T-cells

How to integrate immunotherapies into treatment timelines? Timing is everything! Melanoma..Jim Breitfeller

Dr. Gomella,

I want to thank you for sharing your thoughts on immunotherapy in the article in “High Points and Hurdles: Immunotherapy Moves Forward” online at OncLive.

As a patient/survivor/researcher of stage IV melanoma I know first hand of the importance of integrating immunotherapy into a patient’s treatment. Timing of the therapy is everything, along with the patient’s tumor burden and stage.

In the early phase of cancer, the tumor cells are trying to establish a foothold in a foreign land. They do this by recruiting Tregs with cytokines (Il-10, TFG-b etc.) along with chemoattractants and suppressive cells.

Two of the first arrivals are Tregs along with IL-10. In the early phase of cancer, it has been discovered that the patient’s Tregs are elevated along with IL-10 concentration.

So when the macrophages and immune cells arrive at the tumor’s microenvironment, they encounter suppressive conditions allowing the tumor to continue with growth and progress. The elevated IL-10, IL-4 concentration polarizes the monocyte to the M2, and the T-cells to the Th2 phenotypes and shutting down the immune response.


The macrophage also secretes some chemokines (CCL17, CCL22& CCL18). These chemokines attract other cells that have the cell surface chemokine receptors such as CCR4.


Treg cell migration to Melanoma tumors is mediated by CCL22 released by cancer cells and tumor-associated macrophages. This cytokine plays a role in the trafficking of activated/effector T-lymphocytes to inflammatory sites and other aspects of activated T-lymphocyte physiology. Chemotactic for monocytes, dendritic cells and natural killer cells. Mild chemoattractant for primary activated T-lymphocytes and a potent chemoattractant for chronically activated T-lymphocytes but has no chemoattractant activity for neutrophils, eosinophils, and resting T-lymphocytes This attraction is the beginning of the suprresiveness of the the tumor’s microenviroment.

TAM exert strong immune suppressive activity, not only by producing IL-10 but also by the secretion of chemokines (e.g., CCL17 and CCL22), which preferentially attract T cell subsets devoid of cytotoxic functions such as Treg and Th2.


IL-10 promotes the development of a type 2 cytokine pattern by inhibiting the IFN-γ production of T lymphocytes particularly via the suppression of IL-12 synthesis in accessory cells.




IL-10 suppresses many functions of (NK) cells and T cells, primarily by preventing APCs from producing proinflammatory cytokines



So how can we integrate immunotherapies into treatment timelines to generate the wanted immune response toward the cancer?




  1. First, you need to evaluate the cancer patient and establish their stage.
  2. Second, check the tumor’s genetic code for mutations.

  3. Third, evaluate the patient’s overall health and the ability to go through the therapy

    Here is a generic graphic on how to activate an innate and adaptive response.




1) You need to generate tumor-associated Antigens


2) You need to generate “The Danger Signal” (proinflammatory cytokines secreted, IL-1, IL-6, IL-12, TNF-alpha, Nitric Oxide, PGE2)

3) Block the Suppressive factors that inhibit T-cell activation (Anti-CTLA-4, Anti-PD-1, Anti IL-10r) IL-10 suppresses many functions of (NK) cells and T cells, primarily by preventing APCs from producing proinflammatory cytokines, “The Danger Signal”)

4) Tilt the T-cell Differentiation toward the TH1 phenotype and the Macrophage (TAM), Tumor Associated Macrophage polarization toward the M1 phenotype

5) Alter the tumor’s Microenvironment (addition of Multikine)

6) Produce activated CTLs and Memory T-cells(addition of IL-2)




The Bottom line is we need Sequential Combinatorial Therapy with timing and dosage as the major limiting factors in creating the innate and adaptive immune response.

Legislation for Combinatorial Therapy >> Melanoma ..Jim Breitfeller

Congressman Bilbray, and Congresswomen Maloney and DeLaura are submitting legislation today that, if passed, will provide extended patent protection for investigational drugs that are tested in combination. This will provide a major financial incentive for industry to do the kinds of studies they now find difficult but which offer the best hope for melanoma patients. This legislation came out of meetings MRF had with Congressman Bilbray, whose daughter has Stage III melanoma. We proposed the idea to the Congressman and provided a background document showing how similar action in pediatrics and some infectious diseases has resulted in tremendous progress in drug development. Most doctors agree that real advances in effective treatments will only come through combining two or more drugs together. If these drugs are already approved, doing studies like this are relatively easy. If they are not yet approved--still in clinical trials--they are very difficult. Companies worry that any side effects that arise from a combination study will "taint" the data of their drug and hurt its chances of approval. And they are reluctant to collaborate with other companies on these studies. This legislation will add a "carrot" to the mix and will help accelerate these important studies.

You and Your Doctor—Tackling Your Cancer Together..Melanoma..Jim Breitfeller

You and Your Doctor—Tackling Your Cancer Together

 Talking with your doctor openly about your diagnosis and treatment—and keeping informed every step of the way—will help you work with your doctor to make the best possible decisions about your treatment.

 Educate yourself


 Visit websites designed to educate and assist patients with your type of cancer.

 Ask your doctor where you can learn more about your cancer, its treatment and any ongoing research.

Be informed when you talk to your doctor and treatment team.

Ask questions and be proactive.

It’s your health—and your life!

Talk openly with your doctor Molecular testing for cancer-related genes may not be right for everyone, but by staying informed and asking about such testing, you can be sure that every avenue for treating your cancer has been explored. And for you, that may make the difference between treatment that is effective, or not.


Here are some questions you might ask your doctor:

Are there gene mutations identified for my type of cancer?
 Should my tumor be tested for gene mutations?
What can molecular testing tell me about my cancer?
What can molecular testing tell me about my prognosis?
How might molecular testing affect my treatment plan?
How can I get my tumor or biopsy tested?

Toronto man dies without access to Bristol-Myers Squibb experimental drug..Melanoma.Jim Breitfeller

Published on Wednesday July 11, 2012


Doherty, 48, died in his Toronto home Tuesday after months of publicly fighting for access to a trial-stage melanoma drug.


Despite pleas from his family, his doctor’s approval and a change.org petition just shy of 200,000 signatures, Bristol-Myers Squibb (BMS) repeatedly refused to provide Doherty with compassionate access to its drug, saying it was not yet safe for use outside clinical trials.

His death raises the question: For a patient with no other chance at survival, do drug companies have the responsibility to let them try a drug even if it could harm them?
This particular drug, immune system off-switch blocker BMS-936558, showed early signs of success in phase one testing but is not yet safe for use outside clinical trials, BMS told the Star.
“While we are unable to comment on specific patient cases, we have the deepest sympathy for those who have lost loved ones to cancer,” company spokeswoman Sonia Choi said in an email Wednesday.

The best way to make cancer medicine broadly available to patients, Choi wrote, is through “carefully controlled clinical trials” that establish the risks and benefits, and “by working with health authorities to successfully register these medicines.”
But when Doherty had cancer in 2007, he responded well to a similar, then-experimental BMS drug. His family felt his medical history made him a good candidate for the new drug — besides, when the cancer returned, they had nothing to lose.

“Obviously we are tremendously upset and disappointed that they chose not to make the exception,” said Doug Boyce, Doherty’s lifelong friend, on the phone from Vancouver.

More than that, Boyce said, friends and family are sad and disappointed that there seems to be no system in place for people who reach the end of treatment options to safely access new drugs from pharmaceuticals, without the company fearing ramifications if the drug fails. “It would seem there’s a gap there.”

Doherty was a caring, giving man who was most proud of his family, Boyce said, his voice breaking. The men grew up together in Oshawa, spending many hours at various cottages, pools and golf courses over the years. Boyce remembers his friend as the man who, when given a month to live in 2007, tossed the papers aside and said, “We won’t speak of that again.”

Doherty’s wife, Rebecca Cumming, thanked the public for the support over the past month and directed donations to the David Cornfield Melanoma Fund or the Princess Margaret Hospital Foundation.

“We always remained hopeful that BMS would change its mind and Darcy would have another miracle. Sadly, that did not happen.

Commentary by a Stage IV Melanoma Survivor:

Bristol-Myers Squibb should be ashamed of itself and should be held accountable for the premature death of Mr. Daoherty. BMY could have granted an exception to their rules and allowed Darcy compassionate care due to the fact that he had no other option.

This puts BMS in a very unethical stance with EGG on their face. (Mr. Lamberto Andreotti)





Bristol-Myers Squibb needs cancer patients to enroll in their clinical trials to test them for efficacy. Without the patient, there would be no trial, no FDA approval, and no product. The patient plays a critical role in the Commercialization of this new drug. So why did BMS refuse compassionate use? It wasn't because they would loose money? They have reeped benefit of Yervoy and their other drug revenues to pay cash to acquire Amylin Pharmaceuticals Inc. The price (5.3 billion dollars) in CASH!!!!! Bristol could have given away 4 doses to this dying man as the last hope, but no, Bristol Myers refused!!!!

Is Bristol-Myers committed to their social responsiblity, " Help save lives???

Was their Behavoir Ethical???  Or is it all about GREED???

I think it is the latter. This is not the first time that this situation has reared it's ugly head. There were many Patients that lost their lives because Bristol-Myers Squibb closed it's compassionate use of Yervoy for melanoma patientsts, only to open new Clinical trials to create a shortage for the drug.

As a share holder of this company, I am a shamed of their ethical practices.

Here is what is posted on their website.

Our Commitment
To our patients and customers, employees, global communities, shareholders, environment and other stakeholders, we promise to act on our belief that the priceless ingredient of every product is the integrity of its maker. We operate with effective governance and high standards of ethical behavior. We seek transparency and dialogue with our stakeholders to improve our understanding of their needs.

Interview With Michael B. Atkins, MD Immunotherapies in Melanoma.Jim Breitfeller

Interview With Michael B. Atkins, MD Immunotherapies in Melanoma: Taking Stock
 Alice Goodman, MA; Michael B. Atkins, MD

 Posted: 07/02/2012

 Editor's Note: Immunotherapy is the only treatment that can produce durable tumor regression in patients with metastatic melanoma. With novel molecularly targeted agents also being developed for metastatic melanoma, the hope is to learn how to combine and sequence these therapies and improve survival for patients with this once universally fatal disease. At the 2012 annual meeting of the American Society of Clinical Oncology (ASCO®), Dr. Michael B. Atkins, Deputy Director of the Georgetown Lombardi Comprehensive Cancer Center in Washington, DC, chaired an educational session on immunotherapy in advanced melanoma.

 Medscape caught up with Dr. Atkins to ask him to put into perspective the emerging data on immunotherapy and what questions still need to be answered.

IL-2 Opens the Door Medscape:
 What was the first immunotherapy to show an effect in metastatic melanoma?

Dr. Atkins: High-dose interleukin (IL)-2 received US Food and Drug Administration (FDA) approval for the treatment of patients with metastatic melanoma in 1998. A number of durable responses were observed and 11% of patients were alive at 5 years.[1] More recent studies have shown that patients with elevated lactate dehydrogenase (LDH) levels are much less likely to respond to IL-2, with about a 6% response rate in patients with elevated LDH (all partial responses) and about 21% in those with normal LDH levels.[2] Analysis of molecular profiles shows that a significantly larger proportion of patients with BRAF- and NRAS-mutated tumors respond to IL-2 than those who do not have these mutations. Also, we now have information suggesting that tumors with an inflamed phenotype and immune infiltrates have a 2- to 3-fold improved chance of response relative to those with a noninflamed gene expression pattern.

Michael B. Atkins, MD
Medscape: Has IL-2 been combined with other immunotherapies?

Dr. Atkins:
 IL-2 has been combined with vaccine therapy. Results of a randomized trial found that the combination of IL-2 plus vaccine produced response rates of 22.1% compared with 9.7% with IL-2 alone, and a trend was observed toward improved overall survival.[3] Median survival was 17.6 months with the combination of IL-2 plus vaccine vs 12.8 months with IL-2 alone. Very few relapses were seen beyond 2 years in responding patients, a hallmark of effective immunotherapy. However, lower-than-expected response rates were reported for the IL-2-alone group, calling into question how much of an advance this treatment is. Some questions remain: Is this a proof of concept that the immune response can be focused by a vaccine? Will the findings be relevant with novel immunotherapies? Ipilimumab: A Check-Plus for a Checkpoint Inhibitor Medscape: More recently, ipilimumab, a different type of immunotherapy, was approved by the FDA for the treatment of metastatic melanoma. This drug is referred to as the first checkpoint inhibitor, meaning that it interferes with an important downregulatory property of the immune response.

How does this drug work, and what kinds of outcomes does it achieve?

Dr Atkins: The monoclonal antibody ipilimumab blocks CTLA-4, which serves as a coregulatory protein that shuts off the immune response when it binds to a protein on antigen-presenting cells. Blocking CTLA-4 restores immunity. Ipilimumab has been evaluated in a variety of clinical trials. It is administered intravenously once every 3 weeks for 4 doses on an outpatient basis. Its side effects result primarily from induction of immune reactions against normal tissues, but in general, it produces fewer inflammatory systems (eg, fever, chills, hypotension) than those associated with high-dose IL-2. A recent trial compared ipilimumab plus gp100 vaccine vs ipilimumab alone vs the vaccine alone.[4] In both ipilimumab-containing arms, survival was prolonged. One-year survival was 46%, 44%, and 26% for the 3 arms, respectively. Two-year survival was 22%, 24%, and 14%. Few deaths occurred in the ipilimumab-treated patients after 30 months.

Medscape: What about the safety profile of ipilimumab and patient selection?

Dr Atkins:
The toxicities of ipilimumab are related to activation of the immune system and include colitis, dermatitis, endocrine effects, and hepatitis. In clinical trials, all subgroups benefitted from ipilimumab, with the possible exception of patients with elevated LDH. One feature of ipilimumab is apparent disease progression early in the course of treatment followed by a major response, so we have learned that the effect of treatment is not seen immediately. Pooled data from clinical trials suggest that about 25% of patients with metastatic melanoma have long-term benefit from ipilimumab therapy, and the benefit might be greater with a higher dose of the drug. Also, there is a potential role for maintenance therapy with this agent.

Medscape: Has ipilimumab been studied in combination therapy?

Dr Atkins:
A study was conducted in previously untreated patients with metastatic melanoma in which the patients were randomly assigned to dacarbazine alone or dacarbazine plus ipilimumab.[5] Some experts expected better results than were achieved in this first-line setting, and it is possible that dacarbazine may have compromised outcomes.

Medscape: What are the take-home messages about ipilimumab for metastatic melanoma?

Dr. Atkins:
Ipilimumab enables an immune response and antitumor responses in some individuals. This agent is powerful enough to work in the central nervous system and overcome concurrent immunosuppression. The response to ipilimumab may be associated with autoimmunity. Activity of the drug is seen in patients previously treated with IL-2. This drug is an option for most patients with advanced melanoma. Optimal timing of therapy and severe autoimmune toxicities should be considered. We don't know the answers to all of the questions about how to use ipilimumab. Should it be combined with dacarbazine? Should it be used as first-line or second-line treatment? What is the optimal dose and schedule? Does it have a role in maintenance therapy? What is its role in the adjuvant setting? What combinations should be studied? Some possible combination partners are bevacizumab, GM-CSF [granulocyte-macrophage colony-stimulating factor], high-dose IL-2, and the novel PD-1 antibody. PD-1 Inhibitor: New Kid on the Block Medscape: At the 2012 annual meeting of ASCO®, we heard exciting preliminary reports about a second checkpoint inhibitor called MDX-1106, a PD-1 antibody.

 How does this immunotherapy work, and what are preliminary observations?

 Dr. Atkins:
On activated T-cells, PD-1 serves as the receptor for PD-L1, which is expressed on tumor cells. When PD-L1 binds to PD-1 inside the tumor microenvironment, it paralyzes T-cell immune function. Blocking the interaction between PD-L1 and PD-1 with an antibody provides a specific way to activate the immune system within the tumor microenvironment. It is hypothesized that this would provide a less toxic and more potent means of activating the immune system. Several presentations at ASCO® on this novel immunotherapy showed exciting preliminary results. A large phase 1 study evaluated MDX-1106 given every 2 weeks for up to 2 years in patients with melanoma, renal, and non-small cell lung cancer.[6] Durable responses were seen in all 3 malignancies. In the melanoma patients, about half had tumor shrinkage and some responses were quite significant. This novel therapy will move forward in clinical development for patients with melanoma, either as a single agent or in combination. A number of PD-1 and PDL-1 blockers are under development. Which Patients Are Right for Immunotherapy?

Medscape: How do you select patients for treatment with immunotherapy?

 Dr Atkins: Patients with metastatic melanoma are not all the same. There are 2 basic phenotypes: noninflamed and inflamed. Data suggest that the second phenotype is associated with a better prognosis; that is, the greater the percentage of immune cells within a tumor, particularly CD8+ T cells, the better the prognosis. As mentioned previously, patients with tumors expressing an immune signature are more likely to respond and to exhibit a longer progression-free survival than those with tumors that do not have this signature. Studies suggest that PDL-1 expression appears to be associated with benefit, because patients without PD-L1 expression were less likely to respond to PD-1 antibody.[6-8] Sequencing: Which Therapy, and When? Medscape: What is the current thinking on sequencing of therapies? Dr Atkins: In addition to immunotherapies, several new targeted therapies are on the horizon. Vemurafenib, which targets tumor containing a BRAF V600E mutation, is approved for the treatment of patients with metastatic melanoma, and other BRAF and MEK inhibitors are being studied. These therapies may be able to be used in combination with immune therapies to improve outcomes. Most patients would like a chance to be cured. Immune therapies are the only curative therapies for advanced melanomas. Thus, if patients can receive an immune therapy, it may be better to give it first. For BRAF wild-type tumors (those without the BRAF V600E mutation) and even for the BRAF-mutated tumors, it might make sense to give patients an immunotherapy first to try to produce long-term benefit and reserve the use of a BRAF inhibitor for those patients who don't respond to immunotherapy. Data suggest that giving an immunotherapy first does not reduce the ability to respond to a BRAF inhibitor. On the other hand, patients who progress on vemurafenib do not appear to respond to ipilimumab. In fact, in a small study of 32 patients whose disease progresses on vemurafenib, 50% were dead within 4 months.[9] Only 3 of the 32 patients were alive longer than 1 year, and all of them were back on a BRAF or a MEK inhibitor. These preliminary data suggest that a BRAF inhibitor may not be the best initial therapy for some, if not most, patients with BRAF V600E mutations. A prospective trial is needed to study this question. A sequencing study is being planned by ECOG that has 2 arms: ipilimumab with crossover to vemurafenib at time of progression vs vemurafenib with crossover to ipilimumab at time of progression. The primary endpoint will be overall survival at 2 years. The study should tell us which is the best initial therapy for patients with BRAF mutant metastatic melanoma.

More Work to Be Done Medscape: Are there any potential downsides to combining immunotherapy and targeted therapy?

Dr Atkins: By combining immunotherapy and targeted therapy, the hope is to get the benefits of both worlds. But there are potential problems. Studies suggest that dacarbazine interferes with the immune effects of ipilimumab; however, preliminary data suggest that BRAF inhibitors might increase immune infiltration into tumors, converting the microenvironment from a noninflamed state to an inflamed state. Theoretically, this might mean that the combination of a BRAF inhibitor with immunotherapy might produce synergistic antitumor benefits. Medscape: What can you say to sum up where we are with melanoma immunotherapy in 2012? Dr Atkins: We have IL-2 and ipilimumab, and there are novel immunotherapies on the horizon, including the PD-1 antibody. We will need studies to refine optimal patient selection and identify the best combination treatments, including a BRAF inhibitor either alone or in combination with MEK inhibitors. The field has advanced, and in 2012 it is no longer futile to treat metastatic melanoma. There is a glimmer of hope on the horizon, but there is still a lot of work to be done.

Trying to take the guess work out of finding the correct immunotherapy for Melanoma Patients.Jim Breitfeller

As a stage IV survivor/researcher of Melanoma, I know first hand how it feels to be diagnosed with stage IV cancer. You, your family and your caretaker becomes overwhelmed by the information that must be absorbed and processed to make an educated decision on what therapy you want to try. Don’t get me wrong, your oncologist will play a major in your decision, but is it the right one? Is he trying to fill some of his clinical trials or is he looking out for your best interest? Armed with the right information, one can make the best possible choice. It shouldn’t be a hit or miss approach because with cancer, time is of the essence. Getting to the right therapy before you end up at the late stage IV of your disease is the name of the game. In my therapy, that was my goal, find the right therapy before it overcomes your internal organs and kills you. So, in 2005, I asked my doctor John M Kirkwood if they would take my tumors and biopsy them for gene analysis. Back in 2005, this analytical activity was revolutionary and not done as a standard of care. So in 2005, I contacted Arlet Alarcon from the Molecular Profiling Institute. I tried to convince Dr. John M. Kirkwood, but it was not to be. But now to fast-forward to 2012 and you will see molecular profiling your tumor becoming common practice. So with this in mind, here are some suggestions to get you on the right path. 1.) Assemble a team of doctors that specialize in your cancer. 2.) Make sure they see you as a major part of the team and the decision making. (Be your own advocate) 3.) Learn the medical language so you can research and stay abreast of the new therapies that are being discovered daily. 4.) Learn how your immune system works and how the therapies interact with the immune system. 5.) Be POSITIVE!!!

ACTION! Help Save the Life of Darcy Doherty, Father of Three Children to get immunotherapy drug for melanoma..Jim Breitfeller

ACTION! Help Save the Life of Darcy Doherty, Father of Three Children to get immunotherapy drug Anti-PD-1 (BMS-936558)  for melanoma.




Please write to Dr. Elliot Sigal at Bristol Myer Squibb
Elliott.Sigal@bms.com

Dr. Sigal is the Director of Research at BMS.
Please send a note to Dr. Sigal requesting that BMS open compassionate use for Mr. Doherty. I know it is a long shot/ Hail Mary Pass but, base on my research, this drug with the combination of IL-2 may be able to beat the odds.

Bristol Myer Squibb says "At Bristol-Myers Squibb, we are firmly focused on our Mission to discover, develop and deliver innovative medicines that help patients prevail over serious diseases."

Is this all lip service? Let see if BMS puts their money where their mouth is and grant this compassionate care use for this derserving family. Doherty with his clinal trial of Yervoy (Anti-CTLA-4 therapy) helped get the drug FDA approved through his survival data. The least Bristol could do is to grant the dying man compassionate use of the next generation drug called Anti-PD-1, (BMS-936558)

Bristol-Myer Squibb needs to show some compassion.

It is their ETHICAL Responsibility.

A very Happy Father's Day from a stage IV Melanoma Survivor..Jim Breitfeller

I want to thank all the people that has made this day a very special Day.


As a stage IV Melanoma Survivor, I never dreamed that I would be here today to witness my children spread their wings and learn to fly. My daughter was just entering college when I was first diagnosed and my son, Chris was a sophmore in High School. Today, I am preparing to help my son relocate to Connecticut. He just landed an engineering job at an areospace company. My daughter, Jessica is globe-trotting around the world working on her dual Masters in "International Affairs" and "Natural Resources & Sustainable Development". This day, marks Dee and I as offically "Empty Nesters".

This all was made possible by entering a journey that entailed four clinical trials along with the best and internationally renowned medical team that makes climbing Mt. Everst apiece a cake. And you , My carepage friends that kept me on the "Yellow Brick Road". I have won the "lottery of life."

Many Thanks

Dying man fights to get experimental drug from Bristol-Myers Squibb..Melanoma ..Jim Breitfeller

Emily Jackson Staff Reporter Darcy Doherty’s last chance at life lies in an experimental drug. The yet-to-be-approved treatment is the only option left for the 48-year-old father of three with metastatic melanoma, believes his oncologist Dr. David Hogg, an attending physician at Princess Margaret Hospital. But maker Bristol-Myers Squibb (BMS) refuses to give Doherty the drug, saying it’s not yet safe for use outside the clinical trial, which Doherty was excluded from because of new cancer growth in his brain. That reason is simply not good enough for Doherty’s family and friends. If he will certainly die without the drug, why not let him try it? “They have an ethical responsibility to try to save a life,” his wife Rebecca Cumming said as she handed out “Help Save Darcy” stickers at the Ride to Conquer Cancer Sunday. “I think they’re afraid it will be harder to get the drug to market if the drug brings harm to patients like Darcy.” About 30 family friends were at the fundraiser to promote a change.org petition pressuring BMS to give Doherty access to the drug by Father’s Day. Wait much longer, Cumming said, and it will be too late. More than 171,000 have signed the plea. “We love our dad very much and we want a lot more time with him,” Doherty’s emotional 13-year-old son Ganden said in a video. A cancerous mole was first removed from Doherty’s back in 2003. By 2007 the cancer spread to his brain. He survived because of a then-experimental drug. His doctor said immune system off-switch blocker BMS-936558, which has had success in phase one of testing, could have similar benefits. BMS is aware of the petition, but did not budge on its decision. The company empathizes with patients who have limited treatment options, said spokeswoman Sonia Choi in a statement Sunday. Compassionate use requests are carefully reviewed using information from a patient’s physician, she said. To get access, the benefits must outweigh the risks. “At this time, there are not enough data on BMS-936558 to allow its use outside of a clinical trial.” Choi could not provide a timeframe on when more data might become available. The trial’s final stages are set for later this year or early 2013. “In the long term, the best way to ensure the broadest access for patients is to successfully register a medicine with health authorities through the conduct of well-controlled clinical trials.” “There’s no obligation on the drug companies to provide compassionate relief,” said Bernard Dickens, professor emeritus of health law and policy at the University of Toronto. BMS “can’t invest money in handing out unproven products if they’re not going to get data for study purposes.” But if the drug wasn’t safe enough to test on humans, it would not go to stage-two testing, argued advocate Frank Burroughs, founder of American organization the Abigail Alliance for Better Access to Developmental Drugs. For now, Doherty tires quickly. Sitting in his wheelchair at the fundraiser, the former big-bank financial services managing director called the petition an “amazing show of the human spirit.” He thinks it’s “kind of crazy” that he can’t get the drug. “It doesn’t hurt to give a guy a chance.” Source:http://www.thestar.com/news/article/1209218--dying-man-fights-to-get-experimental-drug-bristol-myers-squibb-won-t-give-him We have seen this type of action numerous times with BMS.They did this with Yervoy in the early days, closing compationate use. They appear to have no compassion or ethics, Just Greed!!!! to make a buck. I believe Bristol Myer Squibb is doing a disservice to the Cancer Community especially the Melanoma Patients.

There is no commitment to patients with stage IV Melanoma.

My Profile as of 2009

My photo
Last July (2005)I was riding my bicycle to work at the Eastman Kodak Research Labs about 3 miles from home. I was wearing a knapsack to carry my things to and from the labs. I started noticing an ache on my back. So I decide to go to the dermatologist. To make the long story short, it was cancer. I knew from my research that I would be needing adjuvant therapy. So I started communicating with Sloan Kettering, University of Pittsburgh Cancer Center, and a couple of others including the Wilmot Cancer Center at Strong. I realized that by telling my story, I might help someone else out there in a similar situation. So to all who are linked by diagnosis or by relation to someone with melanoma, I wish you well. Stay positive, read as much as you can (information helps to eliminate the fear associated with the unknown), and live for today, as no one can predict what tomorrow may bring.

Melanoma and the “Magic Bullet” (Monoclonal Antibodies)

Just to let you know I posted the first draft of the Melanoma and the “Magic Bullet” (Monoclonal Antibodies). on Melanoma Missionary In the Shared File Section. you can download it for 19.95 (Only kidding) it is Free for the taking.


It is 33 pages long and may help you in your quest for the Yellow Brick Broad. Just to let you know it is only the first draft. Revisions are sure to come. I wanted to get it to the people that need it the most, the Melanoma Patients.

Preview:

So, where does Interluekin-2 (IL-2) come into play? According to Byung-Scok et al and recent reports, IL-2 is not needed for developmental CD4+ CD25+ Treg cells in the thymus but does play an important role in the maintenance and function in the peripheral.18 Peripheral is defines as secondary system outside the bone marrow and thymus. It entails the site of antigen, immune system interaction. IL-2 is required for the peripheral generation of Tregs based Abbas’s and colleagues research.19

IL-2 prevents the spontaneous apoptosis of the CD4+ CD25+ Treg cells. It has been reported that patients with multiple advance-stage tumors have elevated levels of Tregs within the tumor microenviroment.20 Interluekin-2 is the survival factor for CD4+ CD25+ Treg cells.21 If the addition of IL-2 is on or before the maximum propagation of the CD4+ T cells, the Tregs population can increase 5-fold in a 96 hour period based on certain growth mediums.

By controlling the addition of the endogenous IL-2, one has a knob to turn and can lead to the control of the expansion of the Tregs. When you combined this control with the anti-CTLA-4 blockage, you can shift the balance of the immune response.

Now here is the catch. The maintenance and function of the CD8+ T-cells require CD4+ cells which secrete IL-2. So we don’t want to deplete the CD4+ cells, we want to control the expansion of the Tregs which are a subset of the CD4+ cells. It has been postulated by some researchers that the Anti-CTLA-4 blockage also suppresses the Treg function in a different mechanism. By using IL-2 as the rate limiting factor, we can suppress the CD4+ CD25+ Treg cell expansion by controlling the concentration and timing of the Inerluekin-2 at the tumor microenvironment.


The Interluekin-2 plays another role in this Melanoma Maze. In a study by Janas et al, Il-2 increases the expressions of the perforin and granzyme A, B and C genes in the CD8+ T-cells. This increase expression causes the CD8+ T-cells to mature into Cytoxic T Lymphocytes (CTLs). The exogenous IL-2 is required for the granzyme proteins. As stated previously, CTLs have cytoplasmic granules that contain the proteins perforin and granzymes. A dozen or more perforin molecules insert themselves into the plasma membrane of target cells forming a pore that enables granzymes to enter the cell. Once in the tumor cell, these enzymes are able to breakup (lyse) the cell and destroy it. This is the beginning of the end for the cancer cells. The tumors begin to shrink and the rest is history,



On the other hand, prolong therapy with Il-2 can result in causing apoptotic death of the tumor- specific CD8+ T-cells.23

Clearly in a clinical setting, timing, dose, and exposure to these drugs play a major roll in the immunotherapy, and can have dramatic effects on the outcome.

All it takes is that one magic bullet to start the immune reaction..

This NCI-led trial is enrolling patients at leading cancer centers throughout the United States. Commenting on these orphan-drug designations, Richard L. Taney, President and CEO of Delcath, stated, “These favorable designations are important steps in our efforts to secure Delcath’s commercial position upon conclusion of our pivotal Phase III trial for metastatic melanoma. We remain steadfast in our commitment to become the leader in the regional treatment of liver cancers and we continue to enroll patients in this study, and advance our technology and the promise that it offers to patients with these deadly forms of melanoma and other cancers of the liver, all with limited treatment options.”

Orphan drug designation, when granted by the FDA’s Office of Orphan Products Development, allows for up to seven years of market exclusivity upon FDA approval, as well as clinical study incentives, study design assistance, waivers of certain FDA user fees, and potential tax credits.
