Brief Summary:
This study will look at Drug-Drug Interactions Between AT2220 (duvoglustat hydrochloride) and alglucosidase alfa (ERT) in Patients with Pompe Disease.

Condition or disease Intervention/treatment Phase
Pompe Disease Drug: duvoglustat hydrochloride Phase 2

Detailed Description:
This will be a multi-center, international, open-label, two-period, fixed-sequence crossover study to evaluate the safety and pharmacokinetic effect of single ascending doses of AT2220 on GAA administered 1 hour before initiation of a single alglucosidase alfa infusion. During Period 1 subjects will receive a single intravenous infusion of alglucosidase alfa. During Period 2, each subject will receive one single oral dose of AT2220 one hour prior to initiation of a single alglucosidase alfa infusion.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 25 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-Label, Multi-Center, Study to Investigate Drug-Drug Interactions Between AT2220 (Duvoglustat Hydrochloride) and Alglucosidase Alfa in Patients With Pompe Disease
Study Start Date : October 2011
Actual Primary Completion Date : December 2012
Actual Study Completion Date : January 2013

Arm Intervention/treatment
Experimental: Cohort 1 Drug: duvoglustat hydrochloride
Single oral dose
Other Name: AT2220
Experimental: Cohort 2 Drug: duvoglustat hydrochloride
Single oral dose
Other Name: AT2220
Experimental: Cohort 3 Drug: duvoglustat hydrochloride
Single oral dose
Other Name: AT2220
Experimental: Cohort 4 Drug: duvoglustat hydrochloride
Single oral dose
Other Name: AT2220

Primary Outcome Measures :
  1. Safety [ Time Frame: 3 months ]
    adverse events (AE) (including infusion reactions), clinical laboratory tests (hematology, urinalysis, serum chemistry including creatine kinase, LDH, alkaline phosphatase, ALT and AST), urine glucose tetrasaccharides (Hex4), 12-lead ECGs, physical examinations, vital signs, and muscle strength tests

  2. Pharmacokinetics [ Time Frame: 1 month ]
    Plasma GAA Cmax and AUC for enzyme activity after an alglucosidase alfa infusion alone and after pre-administration of single ascending doses of AT2220; total protein concentration will also be evaluated for each infusion

Secondary Outcome Measures :
  1. GAA activity in muscle [ Time Frame: Day 3 or Day 7 ]
    GAA levels in skeletal muscle at Day 3 or Day 7 after a single intravenous administration of alglucosidase alfa alone and in combination with single ascending oral doses of AT2220 by measuring GAA enzyme activity and protein levels

  2. AT2220 concentration in muscle [ Time Frame: Day 3 or Day 7 ]
    The concentration of AT2220 in skeletal muscle tissue homogenate on Day 3 or Day 7 after pre-administration of single ascending oral doses of AT2220 in Period 2.

Ages Eligible for Study:   18 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female, diagnosed with Pompe disease and between 18 and 65 years of age, inclusive
  • Subject has been on a stable regimen and dose of alglucosidase alfa or at least 3 month before screening (stable regimen defined as currently receiving alglucosidase alfa every 2 weeks and stable dose defined as not varying by more than ± 10%)
  • Subject has an estimated creatinine clearance ≥ 50 mL/min at Screening; eGFR to be estimated using the 4-parameter MDRD equation:

eGFR (mL/min/1.73 m2) = 175 x (Scr)-1.154 x (Age)-0.203 x (0.742 if female) x (1.212 if African-American)

  • Male and female subjects of childbearing potential agree to use medically accepted methods of contraception during the study and for 30 days after study completion
  • Subject is willing and able to provide written informed consent and is able to comply with all study procedures

Exclusion Criteria:

  • Subject has had a documented transient ischemic attack, ischemic stroke, unstable angina or myocardial infarction within the 3 months before Screening
  • Subject has clinically significant unstable cardiac disease (e.g., cardiac disease requiring active management, such as symptomatic arrhythmia, unstable angina or NYHA class III or IV congestive heart failure)
  • Subject requiring mechanical ventilation or is confined to a wheelchair
  • Subject has a history of allergy or sensitivity to study drug (including excipients) or other iminosugars (e.g., miglustat, miglitol)
  • Subject is pregnant or breastfeeding
  • Subject tests positive for hepatitis B surface antigen or hepatitis C antibody
  • Subject has received any investigational/experimental drug or device within 30 days of Screening
  • Subject has any intercurrent illness or condition that may preclude the subject from fulfilling the protocol requirements or suggests to the investigator that the potential subject may have an unacceptable risk by participating in this study
