Brief summary
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.
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.

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Duvoglustat Concentration In Skeletal Muscle | Day 3 or Day 7 | 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. |
| Total GAA Activity In Skeletal Muscle | Day 3 or Day 7 | 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. |

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.
Time frame: 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
Population: The Per Protocol population included all participants who successfully completed both periods.

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.
Time frame: Day 3 or Day 7
Population: The Per Protocol population included all participants who successfully completed both periods.
