Summary

This is a randomized phase II study to evaluate if the combination of T-DM1 with palbociclib improves progression-free survival compared to single agent T-DM1in patients with metastatic HER2 positive breast cancer

Description

This is a multi-center, randomized, phase II study of T-DM1 with or without palbociclib in the treatment of patients with metastatic HER2-positive breast cancer. Patients will be randomized 1:1 to T-DM1 with or without palbociclib.

Hypotheses: Combination of T-DM1 with palbociclib improves progression free survival compared to single agent T-DM1

Primary objective: Compare progression free survival of the combination arm (T-DM1 with palbociclib) to single agent T-DM1

Secondary objectives i) Compare response rates between both treatment arms ii) Compare overall survival between both treatment arms

Correlative objectives i) Investigate predictive biomarkers of response in blood and archived tumor tissue ii) Investigate mechanisms of resistance for palbociclib in blood and tumor tissue

Exclusion Criteria

HER2 negative tumors
Prior treatment with T-DM1
Prior treatment with CDK 4/6 inhibitors
Known active CNS metastases or carcinomatous meningitis. Patients with stable CNS metastases including brain metastases who have completed a course of radiotherapy are eligible for the study provided they are clinically stable. However, oral corticosteroids for control of CNS symptoms are not allowed on study
Known documented or suspected hypersensitivity to the components of the study drug(s) or analogs
Uncontrolled systemic illness, including but not limited to ongoing or active infection
Symptomatic congestive heart failure, unstable angina pectoris, stroke or myocardial infarction within 3 months
Be pregnant or breast feeding. Female subjects must be surgically sterile or be postmenopausal, or must agree to use effective contraception during the period of therapy. All female subjects with reproductive potential must have a negative pregnancy test (serum or urine) prior to enrollment and must agree to use effective contraception during the period of therapy
Concurrent hormonal or other anti-neoplastic therapy is not allowed. Patients can receive supportive therapy like bone-directed therapy including bisphosphonates or denosumab
