This is a phase IIa study with GA Depot in subjects with Primary Progressive MS. GA Depot will be administered intramuscularly (IM), once every four weeks for 148 weeks.
The purpose of this study is to assess the safety and efficacy of GA Depot to slow the accumulation of disability progression in subjects with Primary Progressive MS.
|Condition or disease||Intervention/treatment||Phase|
|Primary Progressive Multiple Sclerosis||Drug: GA Depot 40mg once monthly Drug: GA Depot 25mg once monthly||Phase 2|
- 30 Subjects with a diagnosis of primary progressive multiple sclerosis (PPMS) who are not treated for PPMS at study entry (except for symptoms relief).
- Study product is GA long-acting injection (GA Depot) which is a combination of extended-release microspheres for injection and diluent (water for injection) for parenteral use. GA Depot will be administered intramuscularly (IM).
- The study duration for an individual subject in the core study will be 156 weeks, consisting of 4 weeks of screening evaluation (weeks -4 to 0), followed by a 148-week open-label treatment period, and a 4 weeks follow up period: through a total of 41 visits.
- Vital signs and safety assessment will be performed at each visit during the study.
- Physical examination will be performed at screening, baseline, 1 week after the second GA Depot treatment, 3 months after first GA Depot treatment and every 3 months thereafter. Last physical examination will be performed at FU visit.
- MRI will be performed at screenings and every 6 months thereafter until the end of the treatment period .
- Safety laboratory tests will be performed at screening, baseline, 1 month after first treatment, and every 3 months thereafter.
- Neurological assessment will be performed at screening, baseline, 3 months, and then every 3 months until end of treatment.

- Safety (Adverse Events and Injection Site Reactions) [ Time Frame: 152 weeks ]Assessment of Adverse events (AEs) & Injection Sites Reactions (ISRs)
- Efficacy (Confirmed Disease Progression) [ Time Frame: 148 weeks ]Time to onset of Confirmed Disease Progression (CDP) assessed by Expanded Disability Status Scale (EDSS). EDSS is a method of quantifying disability in people with MS. The EDSS scale ranges from 0 to 10 in 0.5 unit increments that represent higher levels of disability.
- Efficacy (Whole brain volume change) [ Time Frame: 148 weeks ]MRI assessment of percent of whole brain volume change.
- Efficacy (Cortical volume change) [ Time Frame: 148 weeks ]MRI assessment of percent of cortical volume change.
