Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
BRB-002 is a recombinant fusion protein that is designed to potently block CD47.

Investigational product:: BRB-002 or Matching Placebo for subcutaneous (SC) injection. Up to 48 participants will be enrolled in the study.

Single ascending dose of BRB-002 or Matching placebo will be administered to study participants via subcutaneous (SC) injection in the proposed doses as mentioned below by the site staff. 6 participants will receive BRB-002 and 2 participants will receive placebo.

A range of doses starting at 0.1 mg/kg up to 10 mg/kg or higher as determined by the safety results will be studied across up to 6 participant cohorts. After 2 weeks of observation and when determined safe, subsequent cohorts will be dosed. An adaptive study design will be used that allows for modification of study dose levels based on previous cohort safety data. In each cohort, 6 participants will receive BRB-002 and 2 participants will receive placebo. All participants will be monitored for at least 7 weeks.

Adherence to the intervention will be monitored by the study staff, CRO and Sponsor.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be screened for study eligibility. Once eligibility has been determined, participants will be scheduled for clinic check-in/in-patient dates. On the day of dosing, participants will be given a randomisation number by study staff. This randomisation number will be assigned to either BRB-002 or placebo. At the clinic, only the pharmacy staff will know the assignment to receive BRB-002 or placebo. Syringes of BRB-002 and placebo will be labelled with the randomisation number only for dosing.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The study biostatistician will provide a randomisation list for the study using a randomisation algorithm. This list will link the participant's randomisation number to assignment to BRB-002 or placebo.
