NEO1 and NEO-EXT studies: Long-term safety of repeat avalglucosidase alfa dosing for 4.5 years in late-onset Pompe disease patients
Safety, tolerability, pharmacokinetics, pharmacodynamics, and exploratory efficacy of repeat avalglucosidase alfa dosing (5, 10, or 20 mg/kg qow) for 6 months were evaluated in NEO1 (NCT01898364) in late-onset Pompe disease patients either treatment-naive (Naive) or having received alglucosidase alfa for ≥9 months (Switch). In NEO-EXT (NCT02032524), an ongoing NEO1 extension, long-term safety and pharmacokinetics of repeat avalglucosidase alfa dosing will be monitored over 6 years. Interim safety results after 4.5 years of NEO-EXT are reported here. Mean ages at NEO1 enrollment were: Naive: 44.8 (SD:20.3, range:20-78) years and Switch: 46.7 (SD:14.1, range:21-68) years. Of the 24 NEO1 parti…
Safety, tolerability, pharmacokinetics, pharmacodynamics, and exploratory efficacy of the novel enzyme replacement therapy avalglucosidase alfa (neoGAA) in treatment-naive and alglucosidase alfa-treated patients with late-onset Pompe disease: A phase 1, open-label, multicenter, multinational, ascending dose study
This multicenter/multinational, open-label, ascending-dose study (NCT01898364) evaluated safety, tolerability, pharmacokinetics, pharmacodynamics, and exploratory efficacy of repeat-dose avalglucosidase alfa (neoGAA), a second-generation, recombinant acid α-glucosidase replacement therapy, in late-onset Pompe disease (LOPD). Patients ≥18 years, alglucosidase alfa naïve (Naïve) or previously receiving alglucosidase alfa for ≥9 months (Switch), with baseline FVC ≥50% predicted and independently ambulatory, received every-other-week avalglucosidase alfa 5, 10, or 20 mg/kg over 24 weeks. 9/10 Naïve and 12/14 Switch patients completed the study. Avalglucosidase alfa was well-tolerated; no deaths…
