Researchers are evaluating disitamab vedotin alone or combined with pembrolizumab to treat urothelial cancer that expresses HER2. This study focuses on participants with locally advanced or metastatic urothelial cancer that cannot be removed by surgery. It aims to assess how well the drug works and to monitor the side effects experienced by participants. Participants receive disitamab vedotin intravenously every 2 weeks, either alone or with pembrolizumab given by intravenous infusion on Day 1 of each 6-week cycle. The study includes multiple cohorts receiving different combinations or monotherapy treatments. The treatment period and monitoring last approximately 2 years, with ongoing assessments of drug effects and safety. During the study, participants undergo regular evaluations including imaging scans to measure tumor response, laboratory tests, electrocardiograms to monitor heart function, and assessments of side effects. Researchers measure treatment response using established cancer evaluation criteria and track survival and disease control over about 3 years. Participants are closely monitored for adverse effects and blood levels of the drugs to understand how the treatments behave in the body.

Researchers are evaluating the safety and effects of the study medicine PF-07248144 combined with fulvestrant for treating hormone receptor-positive, HER2-negative advanced or metastatic breast cancer. This study focuses on participants whose breast cancer has worsened after prior treatment with CDK46 inhibitor-based therapy. The trial compares PF-07248144 plus fulvestrant to the current standard treatment involving everolimus and endocrine therapy. Participants will be randomly assigned to one of two groups. One group will take PF-07248144 tablets daily at home in 28-day cycles along with fulvestrant injections administered at the clinic. The other group will receive everolimus tablets daily plus either exemestane tablets or fulvestrant injections, based on the study doctors choice. Treatments will continue according to the schedule for each participant. During the study, participants will undergo regular evaluations including scans to measure tumor response, lab tests, electrocardiograms, and monitoring of side effects. Researchers will track progression-free survival up to about two years, as well as overall survival and response duration up to about five years. Safety and drug levels will also be monitored throughout and after treatment. The total duration of participation may span several years depending on individual outcomes.

Researchers are evaluating a new medicine called PF-08634404 combined with chemotherapy for adults with colorectal cancer that has spread to other parts of the body. The study aims to understand how well this new combination works compared to an existing treatment using Bevacizumab with chemotherapy. The study is a phase 3, double-blind, randomized trial focusing on treatment effectiveness and safety in participants who have not received prior systemic therapy for metastatic disease. Participants are randomly assigned to one of two groups. One group receives PF-08634404 with chemotherapy, and the other group receives Bevacizumab with chemotherapy. Both treatments are given through intravenous IV infusions in cycles. Treatment continues as long as it helps and side effects are manageable. Treatments are administered at clinical sites by trained staff. Participants will have regular visits for treatment, health evaluations, and various tests. After stopping treatment, there is a follow-up visit about 30 to 37 days later to review health and side effects. Further follow-up occurs every 12 weeks by phone, in person, or via health record review to monitor health status and any new treatments. The study duration for each participant is approximately 33 months. Researchers will measure progression-free survival, overall survival, response rates, quality of life, and monitor safety throughout the study.
