“On March 18, 2019, the U.S. Food and Drug Administration (FDA) approved atezolizumab (Tecentriq) in combination with carboplatin and etoposide for the first-line treatment of adult patients with extensive-stage small cell lung cancer.
Approval was based on the IMpower133 study, a randomized (1:1), multicenter, double-blind, placebo-controlled trial in 403 patients with extensive-stage small cell lung cancer who received no prior chemotherapy for extensive stage disease and had ECOG performance status 0 or 1.”
“An accelerated approval has been granted by the FDA for the combination of atezolizumab (Tecentriq) and nab-paclitaxel (Abraxane) as a frontline treatment for patients with unresectable locally advanced or metastatic PD-L1–positive triple-negative breast cancer (TNBC).
“The approval is based on the phase III IMpassion130 trial, in which the addition of the PD-L1 inhibitor atezolizumab to nab-paclitaxel reduced the risk of progression or death by 40% compared with nab-paclitaxel alone in this patient population.”
“On November 2, 2018, the Food and Drug Administration granted accelerated approval to lorlatinib (LORBRENA, Pfizer, Inc.) for patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small cell lung cancer (NSCLC) whose disease has progressed on crizotinib and at least one other ALK inhibitor for metastatic disease or whose disease has progressed on alectinib or ceritinib as the first ALK inhibitor therapy for metastatic disease.
“Approval was based on a subgroup of 215 patients with ALK-positive metastatic NSCLC, previously treated with one or more ALK kinase inhibitors, enrolled in a non‑randomized, dose-ranging and activity-estimating, multi‑cohort, multicenter study (Study B7461001; NCT01970865). The major efficacy measures were overall response rate (ORR) and intracranial ORR, according to RECIST 1.1, as assessed by an independent central review committee.”
“Based on findings from the phase III KEYNOTE-407 trial, pembrolizumab (Keytruda) has been approved by the FDA for use in combination with carboplatin and either paclitaxel or nab-paclitaxel (Abraxane) for the frontline treatment of patients with metastatic squamous non–small cell lung cancer (NSCLC).
“Results from the trial showed combining pembrolizumab with chemotherapy reduced the risk of death by 36% compared with chemotherapy alone in patients with metastatic squamous NSCLC. The median overall survival (OS) was 15.9 months (95% CI, 13.2 – not evaluable) with pembrolizumab versus 11.3 months (95% CI, 9.5-14.8) with chemotherapy alone (HR, 0.64; 95% CI, 0.49-0.85; P = .0017). The OS benefit was observed regardless of PD-L1 expression level, choice of taxane, age, sex, and ECOG performance status.”
“On October 16, 2018, the Food and Drug Administration approved talazoparib (TALZENNA, Pfizer Inc.), a poly (ADP-ribose) polymerase (PARP) inhibitor, for patients with deleterious or suspected deleterious germline BRCA-mutated (gBRCAm), HER2‑negative locally advanced or metastatic breast cancer. Patients must be selected for therapy based on an FDA-approved companion diagnostic for talazoparib.
“Approval was based on EMBRACA (NCT01945775), an open‑label trial randomizing 431 patients (2:1) with gBRCAm HER2‑negative locally advanced or metastatic breast cancer to receive talazoparib (1 mg) or physician’s choice of chemotherapy (capecitabine, eribulin, gemcitabine, or vinorelbine). All patients were required to have a known deleterious or suspected deleterious gBRCA mutation and must have received no more than 3 prior cytotoxic chemotherapy regimens for locally advanced or metastatic disease. Patients were required to have received treatment with an anthracycline and/or a taxane (unless contraindicated) in the neoadjuvant, adjuvant, and/or metastatic treatment setting.”
“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.”
“The FDA has approved enzalutamide (Xtandi) for the treatment of patients with nonmetastatic castration-resistant prostate cancer (CRPC), according to Pfizer and Astellas, the codevelopers of the antiandrogen agent.
“The approval is based on the phase III PROSPER trial, in which the combination of enzalutamide (Xtandi) and androgen deprivation therapy (ADT) reduced the risk of metastases or death by 71% compared with ADT alone for patients with nonmetastatic CRPC. In the double-blind study, the median metastasis-free survival (MFS) was 36.6 months with enzalutamide plus ADT versus 14.7 months with ADT alone (HR, 0.29; 95% CI, 0.24-0.35; P <.0001).”
