A Study To Assess The Tolerability And Clinical Activity Of Gedatolisib In Combination With Palbociclib/Letrozole Or Palbociclib/Fulvestrant In Women With Metastatic Breast Cancer

PHASE 1B STUDY TO ASSESS THE SAFETY, TOLERABILITY, AND CLINICAL ACTIVITY OF GEDATOLISIB IN COMBINATION WITH PALBOCICLIB AND EITHER LETROZOLE OR FULVESTRANT IN WOMEN WITH METASTATIC OR LOCALLY ADVANCED/RECURRENT BREAST CANCER (MBC)

View on ClinicalTrials.gov

Summary

This is a multicenter, open label, Phase 1b study in patients with mBC. This study will have a dose escalation to identify the maximum tolerated dose (MTD) of the combination of gedatolisib plus palbociclib/fulvestrant and gedatolisib plus palbociclib/letrozole and expansion to estimate the objective response rate (OR) of the combination of gedatolisib plus palbociclib/letrozole or palbociclib/fulvestrant.

Detailed Description

This is a multicenter, open label, continuous Phase 1b study in patients with MBC. This study will have a dose escalation and expansion. The dose escalation will identify the maximum tolerated dose (MTD) of the combination of gedatolisib plus palbociclib/fulvestrant and gedatolisib plus palbociclib/letrozole. The expansion will estimate the objective response rate (OR) of the combination of gedatolisib plus palbociclib/letrozole and the combination of gedatolisib plus palbociclib/fulvestrant.

Exclusion Criteria

•Prior treatment with a mechanistic target of rapamycin (mTOR) inhibitor or phosphoinositide 3-kinase (PI3K) inhibitor.
•More than 1 line of prior chemotherapy in the treatment of metastatic or locally advanced/recurrent disease.
•Bone only patients during expansion/efficacy portion.
•Patients with advanced/metastatic disease who have symptomatic visceral spread, and who have life threatening complications needing immediate therapy, such as massive uncontrolled effusions \[pleural, pericardial, peritoneal\], pulmonary lymphangitis, and over 50% liver replacement with tumor.
•Known active uncontrolled or symptomatic Central Nervous System (CNS) metastases.
•Active bacterial, fungal or viral infection.
•Uncontrolled or significant cardiovascular disease.

•Cytotoxic chemotherapy within 4 weeks of investigational product (6 weeks for mitomycin C or nitrosoureas) if immediate prior regimen was administered on an every 3 4 week schedule or 2 weeks of investigational product if immediate prior regimen consisted of weekly therapy.
•Any other anti cancer agents (eg, hormonal, biological, investigational) within 5 times the half life prior to investigational product.
