PD0332991/Paclitaxel in Advanced Breast Cancer

Breast Cancer Clinical Trial

Official title: A Phase 1 Trial of PD0332991 and Paclitaxel in Patients With Rb-Expressing Advanced Breast Cancer

Status Completed

Clinical Trial Summary

This study is a phase I, single arm, open-label trial of PD0332991 in combination with Paclitaxel in patients with Rb-expressing metastatic breast cancer. Up to 20 patients are anticipated to be enrolled to reach the Maximum Tolerated Dose (MTD) of PD0332991 in combination with Paclitaxel. Once the MTD is established, an additional expanded cohort of 10 patients will be enrolled at that dose to establish the Recommended Phase 2 Dose (RP2D), obtain additional safety data and perform exploratory biomarker studies.

Clinical Trial Description

This study is a phase I, single arm, open-label trial of PD0332991 in combination with paclitaxel in patients with Rb-expressing metastatic breast cancer. Patients will be treated as shown in the schema below. Up to 20 patients are anticipated to be enrolled to reach the MTD of PD0332991 in combination with Paclitaxel. Once the MTD is established, an additional expanded cohort of 10 patients will be enrolled at that dose to establish the RP2D, obtain additional safety data and perform exploratory biomarker studies. The primary endpoint will be assessed after one cycle of therapy. Patients will remain on study until dose limiting toxicity, disease progression or physician/patient discretion. Safety assessment will continue for the duration of patient participation. ;
