ABL Bio, Inc.91 enrolled

Overview

This is a Phase 1, FIH, randomized, double-blind, placebo-controlled study designed to assess the safety, tolerability, PK and PD after SAD and MAD in healthy adult participants.

The present study is the first administration of ABL301 in humans. This study will evaluate safety and tolerability and characterize the pharmacokinetic (PK) and pharmacodynamic (PD) profile of ABL301, following IV single ascending dose (Part 1 - SAD), and multiple ascending dose (Part 2 - MAD) administrations, in healthy adult participants. In Part 1 SAD, seven single doses are planned to be administered in an ascending manner: DL1, DL2, DL3, DL4, DL5, DL6 and DL7. Each dose level will comprise 8 participants randomly assigned in an overall 6:2 ratio (ABL301:Placebo), including 1:1 ratio for the first 2 sentinel participants and 5:1 ratio for the remaining participants, to receive a single dose of study drug or placebo, respectively. In Part 2 MAD, three multiples doses are planned to be administered in an ascending manner: DL1, DL2 and DL3. Each dose level will comprise 10 participants randomly assigned in an overall 8:2 ratio (ABL301:Placebo)
