“The U.S. Food and Drug Administration (FDA) recently accepted a supplemental biologics license application (sBLA) and granted Priority Review for atezolizumab (Tecentriq) in combination with bevacizumab (Avastin), paclitaxel, and carboplatin for the first-line treatment of metastatic nonsquamous non–small cell lung cancer (NSCLC). The FDA is expected to make a decision on approval by September 5, 2018.
” ‘Our phase III results showed atezolizumab in combination with bevacizumab, paclitaxel, and carboplatin has the potential to provide a significant survival benefit in the initial treatment of metastatic nonsquamous non–small cell lung cancer,’ said Sandra Horning, MD, Chief Medical Officer and Head of Global Product Development at Genentech.”
“The FDA has received a supplemental biologics license application (sBLA) seeking approval for pembrolizumab (Keytruda) in combination with standard chemotherapy as a treatment for patients with metastatic squamous non–small cell lung cancer (sNSCLC).
“The application is based on findings from the phase III KEYNOTE-407 trial (NCT02775435), which evenly randomized 560 treatment-naive patients with metastatic squamous NSCLC to pembrolizumab combined with carboplatin/paclitaxel or nab-paclitaxel (Abraxane), carboplatin/paclitaxel alone, or nab-paclitaxel alone. The coprimary endpoints were overall survival (OS) and progression-free survival (PFS). Secondary endpoints included objective response rate (ORR) and duration of response.”
“The FDA granted priority review to a supplemental biologics license application that seeks approval of pembrolizumab for use in combination with pemetrexed and platinum chemotherapy for the treatment of patients with newly diagnosed metastatic nonsquamous non-small cell lung cancer.
“Pembrolizumab (Keytruda, Merck) is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2.”
“Adding atezolizumab (Tecentriq) to chemotherapy and an angiogenesis inhibitor led to significant improvement in progression-free survival (PFS) for patients with untreated advanced nonsquamous non–small cell lung cancer (NSCLC), according to results from an ongoing trial presented at the 2018 AACR Annual Meeting.
“In the IMpower150 trial, patients who received the PD-L1 inhibitor along with bevacizumab (Avastin) and chemotherapy had a median PFS of 8.3 months compared with 6.8 months with bevacizumab and chemotherapy. The difference translated into a 38% reduction in the hazard for progression or death (HR, 0.62; 95% CI, 0.52-0.74; P <.0001).”
“Bristol-Myers Squibb Company (NYSE: BMY) today announced initial results from the pivotal Phase 3 study, CheckMate -227, evaluating the Opdivo (nivolumab) 3 mg/kg pluslow-dose Yervoy (ipilimumab, 1 mg/kg) combination in first-line advanced non-small cell lung cancer (NSCLC) patients with high tumor mutational burden (TMB) ≥10 mutations/megabase (mut/Mb). In the study, the combination demonstrated a superior benefit for the co-primary endpoint of progression-free survival (PFS) versus chemotherapy (HR 0.58; 97.5% CI: 0.41 to 0.81; p=0.0002). The PFS benefit was observed regardless of PD-L1 expression levels and in both squamous and non-squamous tumor histology. Additionally, based on an early descriptive analysis, encouraging overall survival was observed with the combination versus chemotherapy in patients with high TMB ≥10 mut/Mb (HR 0.79; 95% CI: 0.56 to 1.10).”
“Merck (NYSE: MRK), known as MSD outside the United States and Canada, today announced results from KEYNOTE-189, a pivotal Phase 3 trial evaluating KEYTRUDA®, Merck’s anti-PD-1 therapy, in combination with pemetrexed (ALIMTA®) and cisplatin or carboplatin for the first-line treatment of metastatic nonsquamous non-small cell lung cancer (NSCLC). Findings showed that the KEYTRUDA-pemetrexed-platinum chemotherapy combination significantly improved overall survival (OS), reducing the risk of death by half compared with chemotherapy alone (HR=0.49 [95% CI, 0.38-0.64]; p<0.00001). In pre-specified exploratory analyses, an OS benefit was observed regardless of PD-L1 expression in the three PD-L1 categories that were evaluated, including: patients whose tumors were negative for PD-L1 (HR=0.59 [95% CI, 0.38-0.92]); patients whose tumors had PD-L1 tumor proportion scores (TPS) of 1-49 percent (HR=0.55 [95% CI, 0.34-0.90]); and patients who had a TPS of greater than or equal to 50 percent (HR=0.42 [95% CI, 0.26-0.68]). The addition of KEYTRUDA to pemetrexed plus platinum chemotherapy also achieved a significant improvement in progression-free survival (PFS), with a reduction in the risk of progression or death of nearly half for patients in the KEYTRUDA combination arm, compared with chemotherapy alone (HR=0.52 [95% CI, 0.43-0.64]; p<0.00001). A PFS improvement in the KEYTRUDA combination group was observed in patients whose tumors were negative for PD-L1 (HR=0.75 [95% CI, 0.53-1.05]); patients with a TPS of 1-49 percent (HR=0.55 [95% CI, 0.37-0.81]); and patients with a TPS greater than or equal to 50 percent (HR=0.36 [95% CI, 0.25-0.52]). These results are being presented today in a plenary session at the American Association for Cancer Research (AACR) Annual Meeting 2018 (Abstract #CT075), with simultaneous publication in The New England Journal of Medicine.”
“The anti-PD1 immunotherapy nivolumab (Opdivo) given prior to surgical resection of stage 1-3 non-small cell lung cancer (NSCLC) was safe and resulted in major pathological responses in 45 percent of the patients, according to data from a clinical trial presented at the AACR Annual Meeting 2018, April 14-18.
“A major pathologic response is defined as 10 percent or fewer viable cancer cells detectable in the resected tumor following neoadjuvant treatment.”
“U.S. regulators have expanded use of AstraZeneca’s lung cancer drug Tagrisso to include initial treatment of patients with a specific genetic mutation, the company said on Wednesday.
“The latest Food and Drug Administration approval includes patients with metastatic non-small cell lung cancer whose tumors have epidermal growth factor receptor (EGFR) mutations as detected by an FDA-approved test.
“Tagrisso, also known as osimertinib, was already approved for use in patients whose lung cancer worsened after treatment with other EGFR therapies and who have developed a secondary mutation.”
“Merck (NYSE:MRK), known as MSD outside the United States and Canada, today announced that the pivotal Phase 3 KEYNOTE-042 trial evaluating KEYTRUDA, Merck’s anti-PD-1 therapy, as monotherapy for the first-line treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC, including nonsquamous or squamous histologies) met its primary endpoint of overall survival (OS). An interim analysis conducted by the independent Data Monitoring Committee (DMC) demonstrated that treatment with KEYTRUDA resulted in significantly longer OS than platinum-based chemotherapy (carboplatin plus paclitaxel or carboplatin plus pemetrexed) in patients with a PD-L1 tumor proportion score (TPS) of ≥1 percent. As part of a pre-specified analysis plan, OS was sequentially tested and was significantly improved in patients with a TPS of ≥50 percent, with a TPS of ≥20 percent and then in the entire study population with a TPS of ≥1 percent. The safety profile of KEYTRUDA in this trial was consistent with that observed in previously reported monotherapy studies involving patients with advanced NSCLC.”
