GB-7624

This is a randomised, double-blinded, placebo-controlled first in human (FIH) trial to evaluate the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and immunogenicity of GB-7624. The trial will have two parts: a SAD component and a MAD component.
Part A (SAD): a total of 24 healthy volunteers are planned to be enrolled across 3 SAD cohorts and will involve the administration of a single subcutaneous (SC) dose of GB-7624 (300 mg, 600 mg, or 1200 mg) or placebo on Day 1 in cohorts A1, A2, and A3.
Part B (MAD): a total of 16 healthy volunteers are planned to be enrolled across 2 MAD cohorts and will involve the administration of multiple SC doses of GB-7624 (300 mg on Day 1 and Day 15 or 600 mg on Day1 and Day 15) or placebo in cohorts B1 and B2.
The decision to escalate between dose levels in the SAD (Part A) and the MAD (Part B) as well as the decision to proceed from Part A to Part B will be based on safety review committee (SRC) review of prior cohorts, blinded available safety, tolerability and PK data.
Study drug will be administered at the study site by trained study site personnel to ensure compliance. The administration of all trial intervention will be recorded in eCRF. Compliance will be assured by direct supervision and witnessing of trial intervention administration.
