|Condition or disease||Intervention/treatment||Phase|
|Myasthenia Gravis||Biological: CV-MG01 Biological: Placebo||Phase 1 Phase 2|
Part A of the trial has been designed as a human safety pharmacology and therapeutic exploratory, parallel group, randomised, placebo-controlled, single centre, Investigator and subject-blind study using adaptive dose and sample size approaches.
At the end of part A of the present study, all patients, including those receiving placebo, will be monitored in an open label, long-term safety follow-up part B of the study to assess the treatment effects over time.

The therapeutic vaccine 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.
Two dose levels: low and high dose.
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.
- Safety [ Time Frame: End of study part A (38 weeks) ]Safety assessed by laboratory tests, vital signs, electrocardiogram (ECG), adverse events, assessment of local tolerance, physical exams
- Immunogenicity [ Time Frame: End of study part A (38 weeks) ]To assess the immunogenic response after subcutaneous injections of CV-MG01 on the plasma levels of anti-peptide antibodies.
- Biomarker [ Time Frame: End of study part A (38 weeks) ]To assess the effect of CV-MG01 subcutaneous injections on the plasma level of acetylcholine receptor antibodies.
- Clinical efficacy [ Time Frame: End of study part A (38 weeks) ]Clinical efficacy assessed by Quantitative MG testing Procedure extended with MG Composite Scale and MG-ADL (myasthenia gravis activities of daily living)
- Immune response [ Time Frame: End of study part A (38 weeks) ]To explore changes in the humoral and cellular immune responses.
