Description

Summary

This is a Phase 2, open-label, single arm trial of pamrevlumab (FG-3019) to estimate pamrevlumab's safety and efficacy in non-ambulatory subjects with DMD.

Official Title

Trial of Pamrevlumab (FG-3019), a Monoclonal Antibody to Connective Tissue Growth Factor, in Non-Ambulatory Subjects With Duchenne Muscular Dystrophy

Details

Each subject will receive pamrevlumab (35 mg/kg) every two weeks by intravenous infusion for at least one year. Subjects may continue on the study for an additional 6 months (for a total of a year and a half) if their pulmonary function tests show stabilization or improvement in the first 52 weeks of treatment and the FibroGen Medical Monitor approves of their continuing. All subjects will be closely monitored for safety. Efficacy assessments will be performed routinely over the course of the study.

You CAN'T join if...

  • Requires ≥16 hours continuous ventilation
  • Prior or ongoing medical condition that, in the investigator's opinion, could adversely affect the safety of the subject, makes it unlikely that the course of 78 weeks of treatment and follow-up would be completed, or could impair the assessment of study results
  • Anticipated spine surgery within 78 weeks
  • Severe uncontrolled heart disease

    1. Need for intravenous diuretics or inotropic support within 3 months prior to screening
    2. Hospitalization for a heart failure exacerbation or arrhythmia in last 3 months
  • Arrhythmia requiring anti-arrhythmic therapy
  • Hospitalization due to respiratory failure in the last 6 weeks
  • Poorly controlled asthma or underlying lung disease such as bronchopulmonary dysplasia
  • Known or suspected active hepatitis B or C or history of HIV
  • BMI ≥40 kg/m^2 or weight>117 kg
  • Exposure to another investigational drug within 28 days prior to start of study treatment
  • Exposure to another investigational drug or another approved product for DMD (e.g.eteplirsen) within 28 days prior to start of study treatment (or 5 half-lives of the product whichever is longer) prior to first screening visit with the exception of deflazacort. Use of deflazacort if regarded by the principal investigator as standard of care is allowed.
