Merck gets USFDA nod for KEYTRUDA as adjuvant treatment for non-small cell lung cancer
KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body's immune system to help detect and fight tumor cells.
Rahway: Merck, known as MSD outside of the United States and Canada, has announced that the U.S. Food and Drug Administration (FDA) has approved KEYTRUDA, Merck's anti-PD-1 therapy, as a single agent, for adjuvant treatment following surgical resection and platinum-based chemotherapy for adult patients with stage IB (T2a ≥4 centimeters [cm]), II, or IIIA non-small cell lung...
Rahway: Merck, known as MSD outside of the United States and Canada, has announced that the U.S. Food and Drug Administration (FDA) has approved KEYTRUDA, Merck's anti-PD-1 therapy, as a single agent, for adjuvant treatment following surgical resection and platinum-based chemotherapy for adult patients with stage IB (T2a ≥4 centimeters [cm]), II, or IIIA non-small cell lung cancer (NSCLC).
The approval is based on data from the pivotal Phase 3 KEYNOTE-091 trial, also known as EORTC-1416-LCG/ETOP-8-15 – PEARLS. The major efficacy outcome measure was investigator-assessed disease-free survival (DFS). In patients who received adjuvant platinum-based chemotherapy following surgical resection, KEYTRUDA reduced the risk of disease recurrence or death by 27% (hazard ratio [HR]=0.73 [95% CI, 0.60-0.89]) versus placebo regardless of PD-L1 expression. The median DFS in patients regardless of PD-L1 expression who received adjuvant platinum-based chemotherapy following surgical resection was nearly five years (58.7 months) for the KEYTRUDA arm versus nearly three years (34.9 months) for the placebo arm, translating to a nearly two-year (23.8 months) DFS improvement versus placebo. In an exploratory subgroup analysis of the 167 patients (14%) who did not receive adjuvant chemotherapy, the DFS HR was 1.25 (95% CI, 0.76-2.05).
KEYTRUDA is an anti-programmed death receptor-1 (PD-1) therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD- L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.
“While there have been many advances for patients with metastatic disease, surgery remains the typical treatment for people with stage IB, II and IIIA non-small cell lung cancer. Unfortunately, many of these patients who undergo surgery still see their disease return,” said Roy S. Herbst, M.D., Ph.D., deputy director and chief of medical oncology, Yale Cancer Center and Smilow Cancer Hospital and ensign professor of medicine (medical oncology) and professor of pharmacology, Yale School of Medicine. “The approval for KEYTRUDA offers a new, important immunotherapy treatment option for stage IB (T2a ≥4 cm), II, or IIIA patients with non-small cell lung cancer following surgery and adjuvant chemotherapy. This provides, for the first time, an adjuvant immunotherapy treatment option for non-small cell lung cancer patients with stage IB disease and regardless of PD-L1 expression.”
“Six years ago, KEYTRUDA was the first anti-PD-1 therapy approved for the first-line treatment of metastatic non-small cell lung cancer and has changed the way metastatic disease is treated. The approval marks the fifth indication for KEYTRUDA in non-small cell lung cancer and the first indication for KEYTRUDA in patients with resected stage IB (T2a ≥4 cm), II, or IIIA disease following adjuvant chemotherapy,” said Dr. Gregory Lubiniecki, vice president, oncology global clinical development, Merck Research Laboratories. “This is an important milestone as we continue our efforts to pursue meaningful advances for patients with non-small cell lung cancer.”
"With this approval, KEYTRUDA is the immunotherapy with an approved option for NSCLC regardless of PD-L1 expression in both the adjuvant and metastatic settings." In addition to today’s approval in the adjuvant setting, KEYTRUDA is indicated in combination with pemetrexed and platinum chemotherapy for the first-line treatment of patients with metastatic nonsquamous NSCLC, with no EGFR or ALK genomic tumor aberrations; in combination with carboplatin and either paclitaxel or paclitaxel protein-bound for the first-line treatment of patients with metastatic squamous NSCLC; as a single agent for the first-line treatment of patients with NSCLC expressing PD-L1 [tumor proportion score (TPS) ≥1%] as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberrations and is stage III where patients are not candidates for surgical resection or definitive chemoradiation, or metastatic; and as a single agent for the treatment of patients with metastatic NSCLC whose tumors express PD-L1 (TPS ≥1%) as determined by an FDA-approved test, with disease progression on or after platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for these aberrations prior to receiving KEYTRUDA," the company stated in a release.
