Researchers are evaluating a drug called sigvotatug vedotin alone and in combination with pembrolizumab, with or without chemotherapy, to determine its safety and effects in people with various advanced solid tumors. This Phase 1 study includes participants with specific cancers like non-small cell lung cancer, head and neck squamous cell cancer, HER2-negative breast cancer, esophageal cancers, ovarian cancer, and others. The trial aims to find out the side effects of sigvotatug vedotin and whether it can treat these solid tumors effectively. The study is divided into four parts. Part A focuses on finding the right dose of sigvotatug vedotin. Part B tests the safety and effectiveness of that dose. Parts C and D look at the safety and effectiveness of sigvotatug vedotin combined with pembrolizumab alone or with chemotherapy drugs carboplatin or cisplatin. Participants receive these drugs intravenously, with pembrolizumab given every 3 or 6 weeks and chemotherapy every 3 weeks depending on the drug. During the study, participants undergo tumor biopsies, physical exams, and disease assessments to monitor treatment effects. Researchers track side effects, lab abnormalities, and dose-limiting toxicities for up to 30-37 days after the last dose of sigvotatug vedotin, and for up to 3 years after pembrolizumab treatment. The study follows participants with regular safety monitoring and evaluations of tumor response throughout the trial.

Researchers are evaluating the safety and effectiveness of a drug called PF-07220060 combined with letrozole compared to other approved treatments (palbociclib, ribociclib, or abemaciclib with letrozole) in adults with breast cancer that is hormone receptor-positive and HER2-negative. This cancer has spread locally or to other parts of the body and has not been treated with systemic anti-cancer therapy for advanced or metastatic disease. The study is a Phase 3, open-label, randomized trial involving multiple centers. Participants will be randomly assigned to receive either PF-07220060 plus letrozole or the investigator's choice of one of the approved CDK4/6 inhibitors (palbociclib, ribociclib, or abemaciclib) combined with letrozole. The treatments are given as drugs with letrozole serving as endocrine therapy. The study compares these treatments in terms of how well they control the cancer and their safety profiles. Participants will visit the study clinic regularly for monitoring during treatment. Researchers will assess how long participants live without their disease worsening or dying from any cause, which is the main outcome measured up to about four years. The study team will monitor each participant's health and response to treatment through these visits to gather information about treatment effects and safety.
