Interim Results from Phase 1b/2 Study Evaluating the Combination of Merck’s KEYTRUDA® (pembrolizumab) and Eisai’s HALAVEN® (eribulin mesylate) Injection in Metastatic Triple-Negative Breast Cancer

Excerpt:

“Merck (NYSE: MRK), known as MSD outside the United States and Canada, and Eisai Inc. today announced new interim data investigating Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), in combination with Eisai’s microtubule dynamics inhibitor, HALAVEN® (eribulin) in patients with metastatic triple-negative breast cancer (TNBC). Findings presented during the 2016 San Antonio Breast Cancer Symposium (SABCS) were based on interim data from 39 evaluable patients and showed an overall response rate (ORR) of 33.3% (n=13/39; 95% CI, 19.5-48.1), with one complete response and 12 partial responses (Abstract #: P5-15-02). ORR was similar between PD-L1-positive and -negative cohorts [PD-L1 positive=29.4% (n=5/17; 95% CI, 11.1-51.1); PD-L1 negative=33.3% (n=6/18; 95% CI, 14.1-54.6)]. HALAVEN and KEYTRUDA are not approved for use in combination.”

Immunotherapy Looks ‘Promising’ in Malignant Mesothelioma

Excerpt:

“Immunotherapy is now offering hope even in one of the most aggressive cancers of all, malignant pleural mesothelioma.

“Malignant mesothelioma is usually diagnosed at a late stage and is essentially incurable. The median overall survival is approximately 12 months with first-line chemotherapy, and median survival with second-line therapy, which has not yet been adequately defined, is typically less than 10 months.

“Early clinical results with the programmed cell death (PD) inhibitors nivolumab (Opdivo, Bristol-Myers Squibb) and pembrolizumab (Keytruda, Merck & Co) show response, yielding survival rates that appear to be improvements on what has been seen historically with chemotherapy.”

Study Findings Show Role for Pembrolizumab and Durvalumab in GBM Treatment, Expert Says

Excerpt:

“Based on encouraging efficacy signals and safety data from separate trials exploring the PD-1 inhibitor pembrolizumab (Keytruda) and the PD-L1 inhibitor durvalumab (MEDI4736), there is a role for checkpoint inhibitors in the treatment of glioblastoma multiforme (GBM). Data from the studies were reported by David Reardon, MD, at the 21st Society for Neuro-Oncology (SNO) Annual Scientific Meeting.

“Reardon said that these results mark important firsts in the field: ‘There has been a lot of anticipation regarding the role of checkpoint inhibitors for glioblastoma and whether we’ll see results in any way similar to the exciting results that have been observed in other cancer indications with this new class of cancer therapeutics.’ ”

Merck Wins Early U.S. Approval for Keytruda in Untreated Lung Cancer

Excerpt:

Merck & Co has won U.S. approval to market its immunotherapy Keytruda for use in previously untreated lung cancer patients two months ahead of schedule, making it the only such drug cleared for first-line treatment.

“The green light from the Food and Drug Administration (FDA), announced by the U.S. drugmaker late on Monday, confirms Merck’s leading position in the hot area of medicines that fight tumors by harnessing the body’s immune system.

“Keytruda’s latest approval is for treating first-line metastatic non-small cell lung cancer (NSCLC) in patients with high-levels of a protein called PD-L1, which makes them more receptive to immunotherapy.”

War of the Checkpoint Inhibitors: Anti-PD-1 Drugs Move into First-Line Treatment in NSCLC


Last year, the U.S. Food and Drug Administration (FDA) approved two anti-PD-1 checkpoint inhibitors, a type of immunotherapy, for treatment of non-small cell lung cancer (NSCLC) in patients whose cancer has progressed after first-line treatment with chemotherapy. Now, the manufacturers of both drugs, pembrolizumab (made by Merck) and nivolumab (made by Bristol-Myers Squibb; BMS) are intent on expanding the indications for use of their drugs. To this end, they have conducted clinical trials testing each as a first-line treatment (i.e., in previously untreated patients), comparing them to standard chemotherapy. Continue reading…


First-Line Pembrolizumab plus Chemotherapy Significantly Improves Outcomes in Advanced NSCLC

Excerpt:

“The addition of PD-1 antibody pembrolizumab to standard first-line chemotherapy for treatment-naïve advanced non-small-cell lung cancer significantly improves response rates and progression-free survival, researchers reported at the ESMO 2016 Congress in Copenhagen today.

“Pembrolizumab is a class of immunotherapeutic anti-cancer drugs called checkpoint inhibitors, which target the mechanism the tumour uses to shut down the body’s immune response.”

Pembrolizumab New Option for First Line Treatment of Patients with Advanced Lung Cancer and High PD-L1 Expression

Excerpt:
“Pembrolizumab is set to become a new option for first line treatment of patients with advanced lung cancer and high PD-L1 expression, according to the results of the phase III KEYNOTE-024 trial presented at the ESMO 2016 Congress in Copenhagen and published in the New England Journal of Medicine.

“‘Pembrolizumab is a PD-1 antibody approved for second line treatment of patients with advanced non-small-cell lung cancer (NSCLC) and PD-L1 expression in their tumour cells,’ said lead author Professor Martin Reck, chief oncology physician, Department of Thoracic Oncology, Lung Clinic Grosshansdorf, Germany. ‘KEYNOTE-024 is the first phase III trial of pembrolizumab as first line treatment in patients with high PD-L1 expression, who represent 27-30% of those with advanced NSCLC.’ ”
