KEYTRUDA Recent Developments
In February 2026, Merck, known as MSD outside of the United States and Canada, announced the presentation of results from the pivotal Phase III LITESPARK-022 trial evaluating KEYTRUDA (Pembrolizumab), Merck’s anti-PD-1 therapy, in combination with WELIREG (Belzutifan), Merck’s first-in-class, oral hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor, given in the adjuvant setting, for patients with clear cell renal cell carcinoma (RCC) following nephrectomy. These late-breaking data will be presented for the first time during an oral abstract session at the 2026 American Society of Clinical Oncology (ASCO) Genitourinary (GU) Cancers Symposium (abstract #LBA418) and are included in the official ASCO GU Press Program.
In December 2025, Astellas Pharma announced positive topline results from an interim analysis of the Phase III EV-304 clinical trial (also known as KEYNOTE-B15) for PADCEV (enfortumab vedotin), a Nectin-4 directed antibody-drug conjugate, in combination with KEYTRUDA (pembrolizumab), a PD-1 inhibitor. This pivotal study evaluated the combination as neoadjuvant and adjuvant treatment (before and after surgery) versus standard of care neoadjuvant chemotherapy (gemcitabine and cisplatin) in patients with muscle-invasive bladder cancer (MIBC) who are eligible for cisplatin-based chemotherapy.

KEYTRUDA Drug Summary
KEYTRUDA (Pembrolizumab) is a humanized monoclonal antibody and immune checkpoint inhibitor that targets the programmed cell death protein 1 (PD-1) receptor on T cells, blocking its interaction with PD-L1 and PD-L2 ligands expressed by tumor cells and thereby restoring anti-tumor immune responses. By enhancing the body’s immune system to recognize and attack cancer cells, KEYTRUDA has demonstrated broad efficacy across multiple malignancies, including Non-Small Cell Lung Cancer, Melanoma, Head and Neck Squamous Cell Carcinoma, and Classical Hodgkin Lymphoma. Administered via intravenous infusion, it can be used as monotherapy or in combination with chemotherapy or other agents, depending on the indication and biomarker status such as PD-L1 expression. Developed by Merck & Co., KEYTRUDA has become one of the most widely used immuno-oncology therapies globally, known for delivering durable responses and improved survival outcomes in a range of advanced and metastatic cancers. The report provides KEYTRUDA’s sales, growth barriers and drivers, post usage and approvals in multiple indications.
