This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
The purpose of this study is to determine the safety and efficacy of PF-07220060 with letrozole compared to approved treatments (ie, palbociclib, ribociclib or abemaciclib with letrozole) in people with breast cancer: * HR-positive (breast cancer cells that need estrogen or progesterone to grow) * HER2-negative (cells that have a small amount or none of a protein called HER2 on their surface); * locally advanced (that has spread from where it started to nearby tissue or lymph nodes) or metastatic disease (the spread of cancer to other places in the body) * who have not received any prior systemic anti-cancer treatment for advanced/metastatic disease. Approximately half of the participants will receive PF-07220060 plus letrozole while the other half of participants will receive the investigator's choice of treatment plus letrozole. The study team will monitor how each participant is doing with the study treatment during regular visits at the study clinic.
AN INTERVENTIONAL, OPEN-LABEL, RANDOMIZED, MULTICENTER PHASE 3 STUDY OF PF-07220060 PLUS LETROZOLE COMPARED TO CDK4/6 INHIBITOR PLUS LETROZOLE IN PARTICIPANTS OVER 18 YEARS OF AGE WITH HORMONE RECEPTOR (HR)-POSITIVE, HER2-NEGATIVE ADVANCED/METASTATIC BREAST CANCER WHO HAVE NOT RECEIVED ANY PRIOR SYSTEMIC ANTICANCER TREATMENT FOR ADVANCED/METASTATIC DISEASE (FOURLIGHT-3)
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
