Details and patient eligibility

About

The purpose of this study is to evaluate the safety and tolerability of ascending doses (Part A) and selected doses (Part B) of BB-031 in acute ischemic stroke patients presenting within 24 hours of stroke onset.

Participants will be randomized to receive one dose of either the investigational drug or placebo and will be followed for 90 days. A total of 156 patients are planned in this study.

Full description

This is a two-part, randomized, placebo-controlled, double-blinded study in acute ischemic stroke patients. In Part A, approximately 36 participants will be randomized in a 3:1 ratio (investigational drug: placebo) into 1 of 3 planned ascending dose groups to determine the dose levels to be studied in Part B. Two dose levels will be chosen based upon a review of all available data including safety, PK, PD and preliminary efficacy. In Part B, approximately 120 participants will be randomized in a 1:1:1 ratio to receive a single dose of two dose levels of study drug or placebo.

All participants will be screened for participation after confirmed diagnosis of an anterior circulation ischemic stroke by neurovascular imaging. Enrolled participants will be followed for 90 days. Radiological outcomes will be assessed by a central blinded reviewer. A Data Safety Monitoring Committee will review safety and preliminary efficacy data throughout the study.
