“In patients with advanced BRAF V600–mutant melanoma, combining the BRAF inhibitor encorafenib (Braftovi) with the MEK inhibitor binimetinib (Mektovi) improved overall survival compared to vemurafenib (Zelboraf) or encorafenib as monotherapy, with a favorable toxicity profile, according to updated results from the phase III COLUMBUS trial.
“Combined BRAF/MEK inhibitor therapy is standard of care in advanced BRAF V600–mutant melanoma, but approved combinations have unique toxicities that may impact the ability to deliver optimal treatment (ie, vemurafenib/cobimetinib [Cotellic] is associated with photosensitivity).”
“The resistance mutation-targeting EGFR inhibitor osimertinib (Tagrisso) demonstrated superior activity against central nervous system (CNS) metastases as compared with chemotherapy or nonselective EGFR inhibitors, two randomized trials of patients with lung cancer showed.
“In a comparison involving patients with untreated EGFR-mutated advanced non-small cell lung cancer (NSCLC), the median CNS progression-free survival (PFS) was not reached in patients who received osimertinib or a first-generation EGFR inhibitor. However, the available data favored the osimertinib arm (95% CI 16.5 months to not reached versus 13.9 months to not reached, HR 0.48, 95% CI 0.26-0.86, P=0.014). Osimertinib also led to a higher response rate.”
“Developing predictive biomarkers will be key to treating patients with triple-negative breast cancer (TNBC), especially when choosing a targeted therapy, said Banu K. Arun, MD.
“In a presentation during the 2018 OncLive® State of the Science Summit™ on Breast Cancer, Arun said there is evidence that PARP inhibitors as well as immunotherapy in combination with various agents may be effective in women with TNBC and BRCA1-related breast cancers, but the science isn’t there yet.”
“A trial assessing the alpha-specific PI3K inhibitor alpelisib with fulvestrant met its primary endpoint of PFS among patients with hormone receptor-positive, HER-2-negative advanced breast cancer with a PIK3CA mutation, according to the agent’s manufacturer.
“The phase 3 global, double-blind SOLAR-1 study included 572 women and men with PIK3CA-mutated hormone receptor-positive, HER-2-negative advanced or metastatic breast cancer that progressed on or following prior aromatase inhibitor treatment with or without a CDK4/6 inhibitor.”
“Combined immunotherapy with two checkpoint inhibitors — nivolumab (Opdivo, Bristol-Myers Squibb) and ipilimumab (Yervoy, Bristol-Myers Squibb) — has shown ‘clinically meaningful’ efficacy in patients with asymptomatic, untreated melanoma metastases to the brain, according to a report regarding new data from the CheckMate 204 open-label phase 2 study.
” ‘Although current practice is to start with surgery, stereotactic radiotherapy, or both followed by immunotherapy or targeted agents, our results support the initiation of immunotherapy to achieve prompt control of both extracranial and brain metastases,’ write the authors.”
“The now-published results from the EMBRACA study confirm that talazoparib (Pfizer), a poly-adenosine diphosphate-ribose polymerase (PARP) inhibitor, prolongs progression-free survival (PFS) in patients with advanced BCRA-positive breast cancer compared with single-agent chemotherapy alone, and that it also significantly improves quality of life.
” ‘This is the largest randomized trial in BRCA mutation carriers [ever undertaken] and demonstrates PARP efficacy,’ Jennifer Litton, MD, associate professor in the Department of Breast Medical Oncology, University of Texas MD Anderson Cancer Center, Houston, told Medscape Medical News in an email.”
“Today, nivolumab (Opdivo) received approval from the U.S. Food and Drug Administration (FDA) for patients with metastatic small cell lung cancer (SCLC) whose cancer has progressed after platinum-based chemotherapy and at least one other line of therapy. Approval for this indication has been granted under accelerated approval based on overall response rate and duration of response.
“This approval for nivolumab had been granted Priority Review from the FDA. It was based on data from the SCLC cohort of the ongoing phase I/II CheckMate-032 study evaluating nivolumab monotherapy in patients who experienced disease progression after platinum-based chemotherapy.”
“Today, the U.S. Food and Drug Administration (FDA) approved pembrolizumab (Keytruda) in combination with pemetrexed (Alimta) and platinum as first-line treatment of patients with metastatic, nonsquamous non–small cell lung cancer with no EGFR or ALK genomic tumor aberrations.
“Pembrolizumab was previously granted accelerated approval for this indication in May 2017 based on improvements in overall response rate and progression-free survival for patients randomized to pembrolizumab administered with pemetrexed and carboplatin as compared with pemetrexed and carboplatin alone in the KEYNOTE-021 study.”
“In a phase II trial funded by the European Organisation for Research and Treatment of Cancer and reported in The Lancet Oncology, van den Bent et al found no evidence of a survival benefit with the addition of bevacizumab (Avastin) to temozolomide in patients with a first recurrence of World Health Organization grade II or III glioma without the 1p/19q codeletion.
“In the open-label trial, conducted at 32 European centers, 155 patients were randomized between February 2011 and July 2015 to receive either temozolomide at 150 to 200 mg/m² on days 1 to 5 every 4 weeks for a maximum of 12 cycles (n = 77) or the same temozolomide regimen plus bevacizumab at 10 mg/kg every 2 weeks until disease progression (n = 78). Previous chemotherapy must have been stopped at least 6 months before enrollment, and radiotherapy, at least 3 months before enrollment. Overall, 44% of patients in the combination group and 47% in the temozolomide group had grade III disease.”
