ATB200-02 Trial Overview

What is the ATB200-02 Study?

The ATB200-02 Study will assess a new investigational treatment option for adults with a rare genetic disorder known as Pompe Disease.

Study Design:

This is an open-label, fixed-sequence, single- and multiple-ascending dose, first-in-human (FIH) study to evaluate the safety, tolerability, Pharmacokinetics (PK), Pharmacodynamics (PD), and efficacy of intravenous ATB200 alone and when co-administered with oral AT2221. The study will be conducted in 3 stages and will have 3 different cohorts.

Main Study Criteria:

This study is an international, multi-center, study of patients with Pompe disease and includes those currently receiving enzyme-replacement therapy (ERT), as well as naïve patients. The purpose of this study is to find out if the co-administration of investigational new drugs ATB200 and AT2221 is safe in adults with Pompe disease.

Primary Outcome Measures:

  • Safety and tolerability as measured by counts of Treatment Emergent Adverse Events (TEAEs), including Infusion Associated Reactions (IARs)
  • Plasma acid α-glucosidase (GAA) activity levels as measured by maximum observed plasma concentration
  • Plasma GAA activity levels as measured by time to reach the maximum observed plasma concentration
  • Plasma GAA activity levels as measured by area under the plasma-drug concentration time curve
