Concurrent SRS, Immunotherapy Improved Response in Melanoma Brain Mets

Excerpt:

“Undergoing immunotherapy within a month of stereotactic radiosurgery (SRS) for the treatment of melanoma brain metastases resulted in an improved response to treatment compared with undergoing the two treatments with a longer amount of time between them, according to the results of a study published in Cancer.

“Patients in the study who underwent the two therapies within 4 weeks of each other had a significantly greater median percent reduction in lesion volume regardless of whether SRS occurred before or after immunotherapy.”

Ipilimumab plus T-VEC Shows Promise for Metastatic Melanoma

Excerpt:

“Talimogene laherparepvec plus ipilimumab demonstrated safety and efficacy among patients with untreated, unresectable advanced melanoma, according to study results published in Journal of Clinical Oncology.

“ ‘Tumor immunotherapy has become an established treatment of metastatic melanoma and is being increasingly applied to other cancer types,’ Igor Puzanov, MD, MSCI, associate professor of medicine at Vanderbilt University School of Medicine, and colleagues wrote. ‘A hallmark of tumors likely to respond to immunotherapy is a lymphocyte-predominant tumor microenvironment. To date, immunotherapy designed to promote lymphocyte accumulation within established tumors, activate lymphocyte function and cytotoxicity, and prevent T-cell suppression has shown the most promise.’ ”

Binimetinib Improves PFS in NRAS-Mutated Metastatic Melanoma

Excerpt:

“The novel MEK inhibitor binimetinib resulted in improved progression-free survival (PFS) and response rates vs dacarbazine in patients with NRAS-mutated advanced unresectable/metastatic melanoma, according to results of an open-label phase III trial.

“ ‘NRAS mutations are present in approximately 20% of all patients with metastatic melanoma,’ said Reinhard Dummer, MD, of the University Hospital Zurich in Switzerland. ‘It activates the MAPK pathway and by this drives cell proliferation and anti-apoptotic mechanisms.’ Preclinical studies have shown that NRAS-mutant melanoma is sensitive to MEK inhibition, and binimetinib inhibits both MEK1 and MEK2. A phase II study showed clinical activity in NRAS-mutant metastatic melanoma.

“The NEMO trial included 402 patients randomized 2:1 to receive either binimetinib (269 patients) or dacarbazine (133 patients; 19 were not treated and were not evaluated for safety). Patients were either treatment-naive or had progressed on or after immunotherapy. The primary endpoint of the study was PFS. The results were presented at the 2016 American Society of Clinical Oncology (ASCO) Annual Meeting held earlier this month in Chicago (abstract 9500).”

Can Patients Discontinue Immunotherapy and Still Benefit?

Excerpt:

“At present in clinical practice, immunotherapy with anti-PD-1 agents is administered indefinitely until intolerable toxicities or progressive disease sets in. But there has been anecdotal evidence that patients who stop treatment may still derive benefit, and now there is evidence of this from a post hoc analysis of a randomized study.

“It comes from the CheckMate 069 trial that evaluated the combination of nivolumab (Opdivo, Bristol-Myers Squibb Company) and ipilimumab (Yervoy, Bristol-Myers Squibb Company) vs ipilimumab alone in patients with metastatic melanoma.

“New results from a post hoc analysis of this trial, presented at the recent American Society of Clinical Oncology (ASCO) 2016 Annual Meeting (abstract 9518), show that a subgroup of patients who discontinued combination immunotherapy because of treatment-related adverse events achieved an impressive overall response rate (ORR) of 66%.”

Total Body Irradiation Did Not Improve Response of Adoptive Cell Transfer

Excerpt:

“Adding total body irradiation to preparative lymphodepletion chemotherapy prior to the adoptive cell transfer of tumor-infiltrating lymphocytes (TILs) had no effect on tumor regression in patients with metastatic melanoma, according to the results of a study published in the Journal of Clinical Oncology.

“However, adoptive cell transfer of TILs did mediate the objective complete response of 24% of patients.

“ ‘The nonmyeloablative chemotherapy regimen thus seemed to provide sufficient lymphodepletion for successful adoptive transfer without the need to add total body irradiation,’ wrote researchers led by Stephanie L. Goff, MD, of the National Cancer Institute.”

Distinct Features Associated With Benefit for BRAF/MEK Inhibition

Excerpt:

“With the development of novel targeted and immunotherapeutic agents that are more efficacious than traditional chemotherapy, treatment paradigms in melanoma have undergone major changes. Current recommendations for first-line systemic therapy for patients with advanced or metastatic melanoma consider BRAF mutation status, tumor growth rate, and the presence or absence of cancer-related symptoms.

“Immunotherapies with agents that block CTLA-4 or PD-1/PD-L1 checkpoints have been associated with durable responses in a subset of patients, and are often considered for patients with low-volume, asymptomatic metastatic melanoma. Targeted therapies, on the other side, are preferred for patients with BRAF-mutant tumors who have symptomatic disease and benefit from the rapid response associated with these agents.”

Long-Term Survival Achieved in Metastatic Melanoma With Personalized Vaccine

Excerpt:

“Two patients with melanoma that had spread to the liver survived for at least 8.5 and 12 years after resection of the hepatic tumor and treatment with patient-specific immunotherapeutic vaccines. The vaccines, designed to activate the immune system against the tumor, were derived from the patients’ own dendritic cells loaded with proteins isolated from their tumors, as described in an article published in Cancer Biotherapy and Radiopharmaceuticals.

“Robert O. Dillman, MD, formerly Vice President Oncology, Caladrius Biosciences, Inc. and currently Chief Medical Officer, NeoStem Oncology (Irvine, CA) and Executive Medical and Scientific Director, Hoag Cancer Institute (Newport Beach, CA) discusses the typically poor prognosis for patients with melanoma of the eye or skin that spreads to the liver, and reports on the potential to achieve long-term survival without disease progression in a subset of patients using the eltrapuldencel-T vaccine. One patient had no disease progression for more than 4.5 years, while the other patient survived and remained disease-free for more than 12 years.”

Bristol-Myers Squibb Receives Positive CHMP Opinion for Opdivo® (nivolumab) in Combination with Yervoy® (ipilimumab) for Treatment of Advanced Melanoma

Excerpt:

Bristol-Myers Squibb Company (NYSE: BMY) announced today that the Committee for Medicinal Products for Human Use (CHMP) has recommended the approval of Opdivo in combination with Yervoy for the treatment of advanced (unresectable or metastatic) melanoma in adults. The CHMP also added an informative statement to the broad indication that relative to Opdivo monotherapy, an increase in progression-free survival (PFS) for the combination of Opdivo with Yervoy is established only in patients with low tumor PD-L1 expression. This CHMP recommendation will now be reviewed by the European Commission (EC), which has the authority to approve medicines for the European Union. Opdivo monotherapy is already approved by the EC for advanced melanoma and previously treated advanced squamous non-small cell lung cancer (NSCLC), and was recommended for approval by the CHMP in February for previously treated advanced or metastatic non-squamous NSCLC and renal cell carcinoma (RCC).”

TILs Advancing as Melanoma Immunotherapy Option

Excerpt:

“After nearly 30 years of research, tumor-infiltrating lymphocyte (TIL) technology is being investigated as a means of producing personalized immunotherapy for patients with metastatic melanoma in a small clinical trial that may help open the door for broader application in other solid tumor types.

“The form of adoptive cell therapy, which utilizes TILs from the patient’s tumor, represents an intriguing way of overcoming the immunosuppressive power of cancer, according to Jeffrey S. Weber, MD, PhD. The melanoma expert provided an overview of the technology and its potential benefit in a lecture for oncologists and oncology professionals presented by Targeted Oncology, a division of MJH Associates, the publisher of OncologyLive, on February 19 in Miami Beach, Florida. Weber is the deputy director of the Laura and Isaac Perlmutter Cancer Center, co-director of its melanoma program, and head of Experimental Therapeutics at NYU Langone Medical Center.”
