Combining BRAF Inhibition, Anti-PD-1 No Help in BRAF-Mutant Melanoma

Excerpt:

“Patients with BRAF-mutant melanoma obtained no survival benefit from combined treatment of anti-BRAF therapy and an immune checkpoint inhibitor, a retrospective analysis showed.

“Median progression-free survival (PFS) was 6.0 to 6.5 months in BRAF-inhibitor naive patients who received a PD-1/PD-L1 inhibitor alone or with a BRAF inhibitor. Patients with prior exposure to a BRAF inhibitor had a median PFS of 8.0 months with anti–PD-1 therapy and 4.5 months with combined treatment. Median overall survival was 10.5 to 12 months with a PD-1/PD-L1 inhibitor alone or in combination with a BRAF inhibitor, regardless of prior BRAF inhibitor exposure status.

“ ‘BRAF inhibitor-refractory patients derived no additional benefit with anti-PD therapy in combination with BRAF inhibition,’ Wen-Jen Hwu, MD, of MD Anderson Cancer Center in Houston, and colleagues concluded in a poster presentation at the 2016 ASCO Annual Meeting in Chicago. ‘Clinical findings are similar with either anti-PD alone or in combination with BRAF inhibition in terms of objective response rate (ORR), disease control rate (DCR), and overall survival (OS).’ ”

Combining Radiation With Immunotherapy Showing Promise Against Melanoma

Excerpt:

“Combining radiation treatments with a new generation of immunotherapies is showing promise as a one-two-punch against melanoma, Loyola Medicine researchers report in the Journal of Radiation Oncology.

“Radiation kills cancer cells by damaging their DNA. Immunotherapies work by harnessing a patient’s immune system to attack and kill cancer cells. When combined, the two therapies appear to have synergistic effects, according to the article by James S. Welsh, MD and colleagues.

“Dr. Welsh is a professor in the department of radiation oncology of Loyola University Chicago Stritch School of Medicine.”

Clinical Trial Versus Standard Protocol: Why and How to Enroll in a Trial


My job at Cancer Commons is to help cancer patients better understand and make decisions about their treatment. Through our Ask Cancer Commons service, I also strive to inform patients about new drugs in trials that they can discuss with their oncologists. Sometimes, I explain the rationale behind a patient’s current or upcoming treatment, and sometimes I try to convince patients to actually get treated, rather than hope that a vegetarian diet and herbal supplements will cure their metastatic disease.

Melanoma: Is Keytruda Game-Changing Therapy? (Video)

Excerpt:

“Pembrolizumab is one of a new class of ‘checkpoint inhibitors’ touted as breakthrough therapy for advanced melanoma. In this 150-second analysis, MedPage Today clinical reviewer F. Perry Wilson, MD, MSCE breaks down the action of the drug, and synthesizes the recent efficacy data.”

Novel Checkpoints Offer Hope After Standard Melanoma Immunotherapies Fail

“Determining the next step for a patient with melanoma who has failed or is not a candidate for existing targeted therapies or immunotherapies can be a challenge.

“However, there is hope, says Omid Hamid, MD, chief of Translational Research and Immunotherapy, and director of Melanoma Therapeutics at The Angeles Clinic.

“ ‘There are times when you throw your hands in the air and say, “I’ve run out of options,” ‘ he says. ‘But, all you need to do is look in another direction, open another cabinet, and realize that there are a ton of new options for our patients. These are nontraditional agents that maybe would not come to mind, but can be very effective in first-line, second-line, or any line.’

“Currently, several new checkpoint inhibitors and costimulatory molecules are being explored. These include those that target glucocorticoid-induced tumor necrosis factor receptor (GITR)—which is expressed on CD4- and CD8-positive T cells—in addition to T-regulatory cells, NK cells, and dendritic cells.”


The Growing Arsenal of Immunotherapy Drugs for Melanoma


Large numbers of immune cells (T cells in particular) are frequently found within or adjacent to melanoma tumors, indicating that the tumors attract the attention—if not the action—of the immune system. True to its reputation as one of the most ‘immunogenic‘ cancers, melanoma now has more U.S. Food and Drug Administration (FDA)-approved immunotherapy (immune system-targeting) drugs than any other cancer type. As a consequence, metastatic melanoma is no longer the universally fatal disease it was even just 3 or 4 years ago. Continue reading…


NHS Patients Barred from BMS' Opdivo, Roche's Kadcyla

“NICE is planning to bar patients with a particular form of lung cancer from access to Bristol-Myers Squibb’s ground-breaking immunotherapy Opdivo on the NHS in England and Wales.

“Opdivo (nivolumab) is the first in a new class of medicines, called PD-1 immune checkpoint inhibitors, to be licensed for use in squamous pre-treated lung cancer patients, and is currently available in the UK to some patients through the Early Access to Medicines Scheme.”


New Promising Drugs for Small Cell Lung Cancer


Any type of advanced lung cancer is bad news, but a diagnosis of small cell lung cancer (SCLC) is a particularly grim one to receive. About 30 years have passed since any new treatments for SCLC were developed, and patients’ responses to standard chemotherapy with etoposide and cisplatin are short-lived. Hopefully, this will change soon.

We begin this post with the immune checkpoint inhibitors, a type of immunotherapy that is explored in seemingly every type of cancer, including SCLC. Reports from two clinical trials of these drugs were recently made available at two meetings on lung cancer treatment. Continue reading…


New Long-Term Data on Opdivo and the Opdivo + Yervoy Regimen Shows Survival Benefit Across Lines of Therapy in Advanced Melanoma

“Bristol-Myers Squibb Company (NYSE:BMY) today announced new long-term data of Opdivo in treatment-naïve BRAF wild-type advanced melanoma from CheckMate -066. In the trial, Opdivo continued to demonstrate superior overall survival versus dacarbazine with 57.7% of patients alive at two years compared to 26.7% of patients treated with dacarbazine. The safety profile of Opdivo was consistent with prior studies. The two-year survival and safety data from CheckMate -066 represent the longest follow-up from a randomized study of any PD-1 immune checkpoint inhibitor in the first-line setting of advanced melanoma. These data will be presented as a late-breaking presentation at the Society for Melanoma Research (SMR) 2015 International Congress in San Francisco, CA from November 18 to 21.”
