Phase 1 / Phase 2: testing Serabelisib for HR+ HER2- Breast Cancer

The study is a Phase 1b/2, multi-center, open-label, dose escalation trial evaluating the safety and preliminary how well it works of sapanisertib and serabelisib (PIKTOR) with fulvestrant and/or other anticancer therapies in participants with HR+/HER2- advanced/metastatic breast cancer.

Official registry: https://clinicaltrials.gov/study/NCT07558733 · Faeth Therapeutics · enrollment listed as 32

What this phase means

Phase 2: researchers already know a roughly safe dose (from phase 1). This stage asks whether the treatment actually helps the condition, and watches side effects more closely.

Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.

What the registry says happens

If you join, the listed intervention(s) are Serabelisib, Sapanisertib, or Fulvestrant. The registry lists allocation as randomized.

Phase 2: testing Pembrolizumab (Keytruda) for Metastatic Colorectal Cancer

Background: The NCI Surgery Branch has developed an experimental therapy that involves taking white blood cells from patients' tumors, growing them in the laboratory in large numbers, and then giving the cells back to the patient. These cells are called Tumor Infiltrating Lymphocytes, or TIL and we have given this type of treatment to over 200 patients with melanoma.
