U.S. Food and Drug Administration Accepts Supplemental Biologics License Application for Opdivo (nivolumab) in Previously Treated Patients with Small Cell Lung Cancer and Grants Priority Review

(BMS) Apr 18, 2018 - Bristol-Myers Squibb Company today announced that the U.S. Food and Drug Administration (FDA) has accepted for priority review its supplemental Biologics License Application for Opdivo (nivolumab) to treat patients with small cell lung cancer (SCLC) whose disease has progressed after two or more prior lines of therapy. The FDA action date is August 16, 2018.

quotesThis will be a welcome addition to our very limited armamentarium for small cell lung cancer. This is a setting in which topotecan is approved, but I don't think there's another approved agent in oncology less enthusiastically endorsed in practice. It's activity is very marginal, toxicity is significant, particularly if administered as it was actually approved, at a dose that is extremely prone to prohibitive myelosuppression. Based on these issues, those who treat relapsed small cell lung cancer have eagerly awaited ANY viable alternative. Though only a minority of patients respond well to nivolumab, the same can be said for topotecan, but nivolumab is typically associated with far more manageable and modest toxicities, and there is a real chance for a more sustained benefit than we could ever anticipate with more conventional chemotherapy. Notably, nivolumab is already listed as a leading consideration in the NCCN guidelines, but it would be very welcome to have a formal FDA approval for nivolumab in this setting. We can also look forward to far more clinical data on nivolumab +/- ipilimumab in SCLC in the coming years.quotes

US FDA Approves Tagrisso As 1st-Line Treatment For EGFR-mutated Non-small Cell Lung Cancer

(AstraZeneca) Apr 18, 2018 - AstraZeneca today announced that the US Food and Drug Administration (FDA) has approved Tagrisso (osimertinib) for the 1st-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumours have epidermal growth factor receptor (EGFR) mutations, (exon 19 deletions or exon 21 L858R mutations), as detected by an FDA-approved test.

H. Jack West, MD (Posted: April 19, 2018)

quotesA long overdue approval that most lung cancer specialists should have come shortly after presentation of the FLAURA trial comparing first line osimertinib to "standard of care" first generation EGFR TKI (either gefitinib or erlotinib) in systemic therapy-naive EGFR mutation-positive NSCLC. The PFS benefit was very substantial (median 18.9 vs. 10.2 mo, HR below 0.5), and osimertinib also has much greater CNS activity to control the risk of future brain mets (quite common in EGFR mutation-positive NSCLC) and also has a more favorable toxicity profile. Though some oncologists and patients will invariably want to hold out on osimertinib and "save" it as a second line therapy to preserve a backup option, that's an erroneous approach, I would content. If it's reserved for later, a maximum of only 50-60% of patients who develop T790M-positive acquired resistance will qualify for it, and only a limited subset of those patients will actually undergo testing to find it. If osimertinib is used as first line therapy, 100% of eligible patients will receive the benefits from it. If it is reserved for second line, likely well under 50% and more like 30-40% of initially eligible patients will ultimately receive it. Overall, the population will likely to far better by starting with osimertinib.quotes

Patients with Advanced Lung Adenocarcinoma and Complex EGFR Mutations Demonstrate Different Response Rates to TKI Therapy

(ELCC 2018) Apr 12, 2018 - The presence of 2 or more EGFR mutations alters the efficacy of treatment with first generation TKIs.

H. Jack West, MD (Posted: April 13, 2018)

quotesThis is a very interesting contribution. We know the response rate to first line EGFR TKIs is 70-80%, but not 100%, and we also see wide variability in how long patients go without progression on initial EGFR TKI therapy. Though we have long oversimplified by presuming that patients with an activating EGFR mutation won't have any other relevant mutations, we are beginning to see that additional mutations may contribute to the variability in outcomes we're seeing. It will be great to see further work from other sources corroborate these observations, but this is very provocative. quotes
