Merck (NYSE: MRK) announced that its COVID-19 treatment, LAGEVRIO™ (molnupiravir), did not achieve a statistically significant reduction in COVID-19 risk in the Phase 3 MOVe-AHEAD trial. The trial involved individuals exposed to COVID-19 and assessed the treatment's efficacy over 14 days. The LAGEVRIO group was only 23.6% less likely to develop COVID-19 compared to the placebo, falling short of the primary endpoint. Despite this, Merck plans to submit the full study results for publication or presentation. LAGEVRIO remains approved in several countries for treating COVID-19 in adults, though not for prevention.

Merck (NYSE: MRK) announced that the FDA accepted two supplemental new drug applications (sNDA) for PREVYMIS™ (letermovir). The first application is for CMV prophylaxis in kidney transplant recipients at high risk, with a PDUFA target date of June 5, 2023. The second extends prophylaxis from 100 to 200 days for patients receiving allogeneic HSCT, target date Sept. 7, 2023. PREVYMIS demonstrated non-inferior efficacy and a superior safety profile to the current standard of care, valganciclovir, in clinical trials. This acceptance could present a significant advance in treatment options for high-risk transplant patients.

Merck (NYSE: MRK) announced significant results from the Phase 3 KEYNOTE-859 trial, where KEYTRUDA combined with chemotherapy improved overall survival (OS) in patients with HER2-negative gastric or gastroesophageal junction adenocarcinoma, reducing death risk by 22% (HR=0.78; p<0.0001). The median OS was 12.9 months for KEYTRUDA plus chemotherapy, compared to 11.5 months for chemotherapy alone. The trial also demonstrated improvements in progression-free survival (PFS) and objective response rate (ORR). Treatment-related adverse events occurred in 59.4% of patients receiving KEYTRUDA plus chemotherapy, indicating a manageable safety profile.

AstraZeneca and Merck (NYSE: MRK) have announced the final analysis results of the overall survival (OS) from the Phase 3 PROpel trial, evaluating LYNPARZA in combination with abiraterone and prednisone.
