study id #: NCT03789734

condition: Muscular Dystrophy, Duchenne

status: not yet recruiting


BLS-M22 is being developed as an anti-myotatin agent for the treatment of Duchenne Muscular Dystrophy (Muscular Dystrophy). A total of 37 subjects participated in this study to confirm the safety of BLS-M22.

intervention: BLS-M22, Placebo

mechanism of action: Anti-myostatin to promote muscle growth


last updated: January 16, 2019

study details

start date: March 2019

estimated completion: October 2019

phase of development: Phase 1

size / enrollment: 37

study description:
This study is a dose Block-randomized, Double-blind, Placebo-controlled and Dose-escalation Phase I Clinical Trial to Evaluate Safety of BLS-M22.
The single ascending dose group participated in 9 patients in each group(500mg, 1000mg, 2000mg/BLS-M22 or Placebo(n=7:2)). The multiple ascending dose group participated in 10 patients(determined dose in SAD/BLS-M22 or Placebo(n=8:2)).

primary outcomes:

  • Adverse events [ Time Frame: up to 4-5 weeks ]
    Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

secondary outcomes:

  • AUClast [ Time Frame: From 0 hours to 24 hours ]
    Evaluation of the pharmacokinetic properties after administration of BLS-M22
  • Immunogenicity(Myostatin specific IgG level in serum) [ Time Frame: up to 4-5 weeks ]
    Evaluation of the immunogenicity after administration of BLS-M22
