Arm Intervention/treatment
Experimental: M6495 Drug: M6495
Participants will receive escalated dose of M6495 bi-weekly on Day 1, 15 and 29 in cohort 1 to 3 and weekly on Day 1, 8, 15, 22, 29 and 36 in cohort 4.

Placebo Comparator: Placebo Drug: Placebo
Participants will receive placebo matched to M6495 bi-weekly on Day 1, 15 and 29 in cohort 1 to 3 and weekly on Day 1, 8, 15, 22, 29 and 36 in cohort 4.




Primary Outcome Measures :
  1. Occurrences of Treatment-emergent Adverse Events (TEAEs), Treatment-related AEs and Serious AEs (SAEs) [ Time Frame: Day 1 up to Day 106 ]
  2. Number of Participants With Clinically Significant Change From Baseline in Vital Signs, Laboratory Parameters and 12-lead Electrocardiogram (ECG) Findings [ Time Frame: Day 1 up to Day 106 ]
    Number of participants with clinically significant change from baseline will be reported.

  3. Occurrences of Injection Site Reactions [ Time Frame: Day 1 up to Day 43 ]

Secondary Outcome Measures :
  1. Maximum Observed Serum Concentration (Cmax) of M6495 [ Time Frame: Day 1 up to Day 106 ]
  2. Dose Normalized Maximum Serum Concentration (Cmax/Dose) of M6495 [ Time Frame: Day 1 up to Day 106 ]
  3. Accumulation Ratio for Cmax (Racc [Cmax]) of M6495 [ Time Frame: Day 1, 15 and 29 ]

    Following Racc parameters will be measured:

    • Racc15 (Cmax): Cmax at Day 15/Cmax at Day 1
    • Racc29 (Cmax): Cmax at Day 29/Cmax at Day 1

  4. Immunogenicity of M6495 as Assessed by Antidrug Antibodies (ADA) Assays [ Time Frame: Day 1 up to Day 106 ]
