Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Study ABX1100-1001 is a first-in-human (FIH), phase 1 study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of a single ascending dose (SAD) and multiple doses (MD) of ABX1100 administered intravenously to healthy participants and patients with LOPD. * Part A features a SAD study with a double-blind, placebo-controlled, randomized design in NHVs involving 3 cohorts (A1-A3). This Part also includes a single dose, open-labeled cohort (A4) in NHVs which will commence after cohorts A1-3. * Part B is a MD, double-blind, placebo-controlled, randomized design in NHVs. The MD Part B will commence after completion of Cohorts A1, A2 and A3 in the SAD Part A and SRC review of these 3 cohorts. * Part C opened for enrollment after the Safety Review Committee (SRC) review of safety, PK and PD data from both Part A and Part B. Part C is a MD, open-label design in patients with Late-Onset Pompe Disease.
