Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Study to evaluate the safety, tolerability, antitumor activity, and pharmacology of MEDI-573 in combination with an aromatase inhibitor (AI) in adult subjects with HR+, HER2-negative MBC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1b/2, multicenter, open-label study to evaluate the safety, tolerability, antitumor activity, and pharmacology of MEDI-573 in combination with an AI in adult subjects with HR+, HER2-negative MBC. This study has 2 phases: a dose-evaluation phase (Phase 1b) and a randomization phase (Phase 2).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

MEDI-573 10 mg/kg + AI

Participants who will be enrolled in Phase 1b Cohort A of the study will receive intravenous infusion of MEDI-573 10 mg/kg on Day 1 of each 21-day cycle and AI of the investigator's choice (letrozole, anastrozole, or exemestane) orally once daily until unacceptable toxicity, documentation of disease progression, or withdrawal for other reasons.

Group Type EXPERIMENTAL

MEDI-573

Intervention Type DRUG

Intravenous infusion of MEDI-573 (10 or 30 or 45 mg/kg) will be administered on Day 1 of each 21-day cycle until unacceptable toxicity, documentation of disease progression, or withdrawal for other reasons.

Aromatase Inhibitor

Intervention Type DRUG
