A Study Evaluating the Efficacy and Safety of Multiple Immunotherapy-Based Treatment Combinations in Patients With Metastatic or Inoperable Locally Advanced Triple-Negative Breast Cancer (Morpheus-TNBC)


Brief description of study

This is a Phase Ib/II, open-label, multicenter, randomized umbrella study evaluating the efficacy and safety of multiple immunotherapy-based treatment combinations in patients with metastatic or inoperable locally advanced TNBC who had disease progression during or following first-line metastatic treatment with chemotherapy.

The study will be performed in two stages. During Stage 1, participants will be randomized to capecitabine (control) or an atezolizumab-containing doublet or triplet combination. Those who experience disease progression, loss of clinical benefit, or unacceptable toxicity may be eligible to receive a new doublet combination treatment in Stage 2 until loss of clinical benefit or unacceptable toxicity. New treatment arms may be added and/or existing treatment arms may be closed during the course of the study on the basis of ongoing clinical efficacy and safety as well as the current treatments available.
