    Article from OncLive curated by Editor in Chief George Lundberg, MD, who notes:

    The U.S. Food and Drug Administration (FDA) has approved another new drug for people with metastatic non-small cell lung cancer (NSCLC) tumors that have high levels of a protein called PD-L1.

    Excerpt:

    “On April 11, 2019, the Food and Drug Administration approved pembrolizumab (KEYTRUDA, Merck Inc.) for the first-line treatment of patients with stage III non-small cell lung cancer (NSCLC) who are not candidates for surgical resection or definitive chemoradiation or metastatic NSCLC. Patients’ tumors must have no EGFR or ALK genomic aberrations and express PD-L1 (Tumor Proportion Score [TPS] ≥1%) determined by an FDA-approved test.

    “Pembrolizumab was previously approved as a single agent for the first-line treatment of patients with metastatic NSCLC whose tumors express PD-L1 TPS ≥50%.”

    Excerpt from Cancer Network:

    “Researchers found that in patients with non–small-cell lung cancer (NSCLC) and a Tumor Proportion Score (TPS) ≥ 50, pembrolizumab plus chemotherapy failed to improve overall survival (OS) or progression-free survival (PFS) compared with pembrolizumab alone.

    “Results from the study were presented in a poster presentation at the International Association for the Study of Lung Cancer (IASLC) 19th World Conference on Lung Cancer, held September 23–26 in Toronto.”

    Excerpt from Healio:

    “The FDA granted priority review designation to a supplemental biologics license application that seeks approval of pembrolizumab for use in combination with chemotherapy as first-line treatment of metastatic squamous non-small cell lung cancer regardless of PD-L1 expression.

    “The agency set a target action date of Oct. 30.”

    Predicting If an Immune Checkpoint Drug Will Work

    Emma Shtivelman, PhD

    Drugs that activate the immune system to attack cancer in a process known as immune checkpoint blockade (ICB) are a focus of intense investigation. A number of them are already approved by the U.S. Food and Drug Administration (FDA) for various cancers; namely, the anti-CTLA4 antibody ipilimumab (Yervoy), two anti-PD-1 antibodies: pembrolizumab (Keytruda) and nivolumab (Opdivo), and three anti-PD-L1 drugs: atezolizumab (Tecentriq), avelumab (Bavencio)… Read more »

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

    Emma Shtivelman, PhD

    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… Read more »

    To PD-L1 or Not to PD-L1: That Is the Question

    Emma Shtivelman, PhD

    These days, it seems that I write mostly about immune checkpoint blockade drugs, or some other new immunotherapy treatment for cancer. This post is no different—it covers PD-L1, a protein that is at the center of clinical decisions for selecting patients who are likely to benefit from treatment with an anti-PD-1 or anti-PD-L1 drug.
