Gaucher Disease Clinical Trial
Official title:
An Open-Label, Multicenter, Long-Term Extension Study To Assess The Safety, Efficacy, And Pharmacodynamics Of AT2101 In Adult Patients With Type 1 Gaucher Disease
This study evaluated the long-term safety and efficacy of afegostat tartrate in participants with Gaucher disease who were enrolled in a previous Phase 2 study of afegostat tartrate.
This was an open-label, long-term extension study of afegostat tartrate in participants with type 1 Gaucher disease who successfully completed Study GAU-CL-202 (NCT00446550). Participants could enter the study immediately upon completion of participation in the lead-in study GAU-CL-202, or at any later time point. Participants received 225 milligram (mg) afegostat tartrate, administered orally for 30 months, and remained in 1 of the 2 randomized treatment regimens of Study GAU-CL-202: afegostat tartrate once daily (QD) for 3 consecutive days, then no afegostat tartrate for 4 consecutive days (consecutive 3-days-on/4-days-off) or QD for 7 consecutive days, then no afegostat tartrate for 7 days (consecutive 7-days-on/7-days-off). Amendment 2 removed the 7-days-on/7-days-off regimen and added an alternative 3-days-on/4-days-off regimen: afegostat tartrate QD on Monday, Wednesday, and Friday, then no afegostat tartrate on Tuesday, Thursday, Saturday, and Sunday (MWF 3-days-on/4-days-off). Once Amendment 2 was implemented at a site, participants assigned to the 7-days-on/7-days-off regimen switched to a 3-days-on/4-days-off regimen; those on the original 3-days-on/4-days-off regimen could switch to the MWF 3-days-on/4-days-off regimen. Amendment 4 removed the original 3-days-on/4-days-off regimen and any participants still on that regimen switched to the MWF 3-days-on/4-days-off regimen. Study visits occurred every 3 months for 30 months. Participants were contacted approximately 1, 3, and 6 months after the end of treatment (EOT) or early termination for follow-up assessments. ;
