OP-1250 Hormone Therapy with Targeted Therapy for Advanced HR+, HER2- Breast Cancer

A Phase 1b Open-Label Multicenter Study of OP-1250 in Combination With the CDK4/6 Inhibitor Ribociclib or With the PI3K Inhibitor Alpelisib in Adult Subjects With Advanced and/or Metastatic HR Positive, HER2 Negative Breast Cancer Scientific Title

Purpose
To study the safety, effects (good and bad), and anti-cancer activity of OP-1250, an experimental hormone therapy, with ribociclib (Kisqali®) CDK 4/6 inhibitor or alpelisib (Piqray®) PI3K inhibitor.
Who is this for?
People with advanced (some stage III) or metastatic (stage IV) hormone receptor positive (ER+ and/or PR+), HER2 negative (HER2-) breast cancer who have received 1-2 hormone therapies for advanced or metastatic disease. You must not have received more than 1 chemotherapy for advanced or metastatic disease.    Full eligibility criteria

  • <ul class="seamTextUnorderedList"> <li class="seamTextUnorderedListItem">OP-1250 is an experimental hormone therapy called a selective estrogen receptor downregulator (SERD) and complete estrogen receptor antagonist (CERAN). SERDs bind to and break down estrogen receptors, and CERANs block estrogen receptors.</li> <li class="seamTextUnorderedListItem">Ribociclib (Kisqali®) is a type of targeted therapy called a CDK 4/6 inhibitor. CDK 4/6 inhibitors block two enzymes, CDK4 and CDK6, that help cancer grow.</li> <li class="seamTextUnorderedListItem">Alpelisib (Piqray®) is a type of targeted therapy called a PI3K inhibitor. Blocking the PI3K pathway may slow or stop cancer cells from growing.</li></ul>
