Clinical Trial 24445

• Overview

  Study Title:

  Open-Label Umbrella Study to Evaluate Safety and Efficacy of Sapanisertib and Serabelisib (PIKTOR) in Various Combinations in Patients with HR+/HER2- Advanced or Metastatic Breast Cancer

  Summary:

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

  Objective:

  Primary Objective: * To evaluate the safety and tolerability of PIKTOR with fulvestrant and/or other anticancer therapies and to determine the maximum tolerated doses (MTDs)/recommended phase 2 doses (RP2Ds) of combination treatment Secondary Objective: * To evaluate the preliminary efficacy of PIKTOR with fulvestrant and/or other anticancer therapies

  • Participants who have received a prior PI3K, AKT, mTORC1/2, or dual PI3K/mTOR inhibitor.
  • Strong CYP3A4 inhibitors, strong CYP1A2 inhibitors or CYP1A2 inducers, or clinically significant CYP3A4 inducers within 7 days before the first dose of study intervention, or participants who require treatment with strong CYP3A4 inhibitors or inducers during the study.
  • Prolongation of QTc interval to >480 ms.
  • Type 1 or Type 2 diabetes mellitus on insulin.
