Brief Summary:
This study is designed to determine the efficacy and safety of durvalumab in combination with novel oncology therapies with or without paclitaxel and durvalumab + paclitaxel for first-line metastatic triple negative breast cancer

Condition or disease Intervention/treatment Phase
Triple Negative Breast Neoplasms Drug: Durvalumab Drug: Capivasertib Drug: Oleclumab Drug: Paclitaxel Drug: Trastuzumab deruxtecan Drug: Datopotamab deruxtecan Phase 1 Phase 2

Detailed Description:

This is a Phase IB/II, 2-stage, open-label, multicenter study to determine the efficacy and safety of durvalumab in combination with novel oncology therapies (i.e. therapies designed for immune modulation) with or without paclitaxel and durvalumab + paclitaxel as first-line treatment in patients with metastatic triple negative breast cancer (TNBC). The study is designed to concurrently evaluate potential novel treatment combinations with clinical promise using a 2-stage approach. The study will use a Simon 2-Stage design to evaluate which cohorts may proceed to expansion.

Part 1 is a Phase IB study of safety and initial efficacy, and Part 2 may expand patient enrollment if adequate efficacy signal is observed in Part 1. The treatment regimens evaluated in Part 2 will depend on the evaluation of safety and efficacy outcomes in Part 1.

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 240 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Part 1:

At least 20 patients in the durvalumab-paclitaxel arm and at least 30 patients in each of the other novel treatment combination arms will be enrolled, for a total of approximately 140 patients (durvalumab + paclitaxel arm and 4 novel treatment combination arms). Additional patients may be enrolled in order to have 20 or 30 evaluable (i.e. dosed) patients per durvalumab - paclitaxel arm or novel treatment combination arm, respectively.

Part 2:

Approximately 27 patients will be assigned to each treatment arm, for an anticipated total of 57 response-evaluable patients per arm (ie, 30 patients in Part 1 and 27 patients in Part 2 per treatment arm, with the exception of Arm 1, which will enroll 20 patients in Part 1 and will not be expanded to Part 2). Patient expansion from 30 patients in Part 1 to an additional 27 patients from Part 2 will be determined based on a futility analysis utilizing a Simon 2 Stage design.
