About this study

Official title: An Open-Label, Multi-Center, International Study to Investigate Drug-Drug Interactions Between AT2220 and Alglucosidase Alfa in Patients With Pompe Disease

This study evaluates drug-drug interactions between AT2220 (duvoglustat) and recombinant human alpha-glucosidase (rhGAA, also known as alglucosidase alfa) in participants with Pompe Disease.

Read the detailed description

This was a multi-center, international, open-label, two-period, fixed-sequence crossover study to evaluate the safety and pharmacokinetic effect of single ascending doses of duvoglustat on rhGAA administered 1 hour before initiation of a single rhGAA infusion. During Period 1, participants received a single intravenous infusion of rhGAA. During Period 2, each participant received a single oral dose of duvoglustat 1 hour prior to initiation of a single rhGAA infusion.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number Of Participants Who Experienced Severe Treatment-Emergent Adverse Events (TEAEs)

    A TEAE was defined as an adverse event (AE) with an onset date on or after the first dose of investigational medicinal product (IMP), or an AE with an onset date before the first dose date that worsened in severity after the first dose date. A severe AE was defined as an AE that was incapacitating and required medical intervention. The number of participants who experienced 1 or more severe TEAEs after dosing on Day 1 up to Day 60 (includes end of study follow-up period) is reported.

    A summary of serious and all other non-serious AEs, regardless of causality, is located in the Reported Adverse Events module.

    Measured: Day 1 after dosing up to Day 60

  2. Pharmacokinetics (PK): Maximum Measured Plasma Concentration (Cmax) Of Total GAA And rhGAA Protein In Plasma In Participants With Pompe Disease

    The Cmax of total GAA and rhGAA protein in plasma was measured after a single rhGAA intravenous infusion and after pre-administration of single ascending oral doses of duvoglustat.

    During Treatment Period 1, participants received a single intravenous infusion of rhGAA. During Treatment Period 2, participants received a single oral dose of duvoglustat 1 hour before initiation of a single rhGAA intravenous infusion. PK samples were taken at time points Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2.

    Measured: Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2

  3. PK: Time To The Maximum Plasma Concentration (Tmax) Of Total GAA And rhGAA Protein In Plasma In Participants With Pompe Disease

    The Tmax of total GAA and rhGAA protein in plasma was measured after a single rhGAA intravenous infusion and after pre-administration of single ascending oral doses of duvoglustat.

    During Treatment Period 1, participants received a single intravenous infusion of rhGAA. During Treatment Period 2, participants received a single oral dose of duvoglustat 1 hour before initiation of a single rhGAA intravenous infusion. PK samples were taken at time points Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2.

    Measured: Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2

  4. PK: Elimination Half-life (T1/2) Of Total GAA And rhGAA Protein In Plasma In Participants With Pompe Disease

    The T1/2 of total GAA and rhGAA protein in plasma was measured after a single rhGAA intravenous infusion and after pre-administration of single ascending oral doses of duvoglustat.

    During Treatment Period 1, participants received a single intravenous infusion of rhGAA. During Treatment Period 2, participants received a single oral dose of duvoglustat 1 hour before initiation of a single rhGAA intravenous infusion. PK samples were taken at time points Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2.

    Values presented are arithmetic mean (percent coefficient of variation, [CV%]). The number of participants analyzed for some cohorts are reduced because the terminal phase of the concentration profile for these participants was not estimable.

    Measured: Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2

  5. PK: Area Under The Plasma Concentration Versus Time Curve From Time 0 To The Time Of The Last Measurable Concentration (AUC0-t) Of Total GAA And rhGAA Protein In Plasma In Participants With Pompe Disease

    The AUC0-t of total GAA and rhGAA protein in plasma was measured after a single rhGAA intravenous infusion and after pre-administration of single ascending oral doses of duvoglustat.

    During Treatment Period 1, participants received a single intravenous infusion of rhGAA. During Treatment Period 2, participants received a single oral dose of duvoglustat 1 hour before initiation of a single rhGAA intravenous infusion. PK samples were taken at time points Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2.

    Measured: Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2

  6. PK: AUC From Time 0 Extrapolated To Infinity (AUCinf) Of Total GAA And rhGAA Protein In Plasma In Participants With Pompe Disease

    The AUCinf of total GAA and rhGAA protein in plasma was measured after a single rhGAA intravenous infusion and after pre-administration of single ascending oral doses of duvoglustat.

    During Treatment Period 1, participants received a single intravenous infusion of rhGAA. During Treatment Period 2, participants received a single oral dose of duvoglustat 1 hour before initiation of a single rhGAA intravenous infusion. PK samples were taken at time points Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2.

    The number of participants analyzed for some cohorts are reduced because the terminal phase of the concentration profile for these participants was not estimable.

    Measured: Predose, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, and 24 hours, and 3 or 7 days postdose during Periods 1 and 2, and 24 to 30 days postdose during Period 2

Secondary outcomes (2)
  1. Total GAA Activity In Skeletal Muscle

    The total GAA activity in skeletal muscle was measured after a single intravenous administration of rhGAA alone and after pre-administration of single ascending oral doses of duvoglustat. Participants were assessed using skeletal muscle biopsies at either Day 3 or Day 7 during Treatment Periods 1 and 2.

    Measured: Day 3 or Day 7

  2. Duvoglustat Concentration In Skeletal Muscle

    The concentration of duvoglustat in skeletal muscle tissue homogenate was measured after pre-administration of single ascending oral doses of duvoglustat during Treatment Period 2. Participants had skeletal muscle biopsies at either Day 3 or Day 7 during Treatment Period 2.

    Three participants were excluded from this analysis due to the following reasons: treatment sequence was inadvertently switched due to study site error, follow-up biopsy sample could not be conclusively identified, or muscle biopsies were mislabeled at the clinical site.

    Values presented are arithmetic mean (percent coefficient of variation, [CV%]) because of the prevalence of participants with values below the limit of quantification. Concentrations below the limit of quantification were treated as zero.

    Measured: Day 3 or Day 7
