The active targeted immunotherapy candidate, CV-MG01 comprises two short synthetic peptides separately conjugated to a carrier protein for the potential treatment of myasthenia gravis
3 consecutive subcutaneous injections of CV-MG01. The three injections are planned for each patient on Days 1, 29 (+/- 3 days) and 85 (+/- 7 days), respectively.
Other Name: Myasterix
Placebo Comparator: Placebo
Aluminium hydroxide adjuvant alone
3 consecutive subcutaneous injections of placebo. The three injections are planned for each patient on Days 1, 29 (+/- 3 days) and 85 (+/- 7 days), respectively.
- Clinical efficacy [ Time Frame: 24 weeks ]To assess the efficacy of 3 subcutaneous injections of CV-MG01 compared to placebo, as measured by a decrease from baseline of the QMG total score at 24 weeks after the first injection (equivalent to 12 weeks after last injection).
- Safety (ohysical examens and laboratory tests) and local tolerance (FDA grading scale) [ Time Frame: 24 weeks ]
Evaluation of treatment emergent adverse events (TEAEs) including local injection site reactions (severity assessed with an overall grading scale following the FDA recommendation (FDA, CBER, September 2007)).
General safety monitoring via physical examinations, vital signs (VS), ECG and standard laboratory tests (clinical chemistry, haematology and urinalysis).
- Efficacy - Responder rate [ Time Frame: 24 weeks ]Proportion of patients with improvement or worsening by ≥ 3 points in the QMG score at week 24 after the first injection in the active group compared to the placebo group
