Description

Summary

HOPE-3 is a multi-center, randomized, double-blind, placebo-controlled clinical trial evaluating the safety and efficacy of a cell therapy called CAP-1002 in study participants with Duchenne muscular dystrophy (DMD) and impaired skeletal muscle function. Non-ambulatory and ambulatory boys and young men who meet eligibility criteria will be randomly assigned to receive either CAP-1002 or placebo every 3 months for a total of 4 doses during a 12-month period. All participants will be eligible to receive CAP-1002 for an additional 12 months as part of an open label extended assessment period.

Official Title

A Phase 3, Randomized, Double-Blind, Placebo-Controlled Trial Evaluating the Efficacy and Safety of Human Allogeneic Cardiosphere-Derived Cells for the Treatment of Duchenne Muscular Dystrophy

Details

Up to 68 eligible study participants will be randomized to either CAP-1002 or placebo in a 1:1 ratio. The trial will include visits at Screening, Baseline/Day 1, Week 4, and Months 3, 6, 9, and 12 with IV infusions of CAP-1002 or placebo on Day 1 and Months 3, 6, and 9.

The primary analysis of efficacy and safety will be performed at Month 12 following 4 administrations of CAP-1002 or placebo.

The primary efficacy endpoint is the mean change from baseline in upper limb function as assessed by the full Performance of the Upper Limb test, version 2.0 [PUL 2.0] at the 12-month time point. Secondary endpoints evaluated at the 12-month time point include assessment of changes in cardiac muscle function and structure by cardiac magnetic resonance imaging [cMRI], changes in hand-to-mouth function [eat 10-bites assessed by the Duchenne Video Assessment (DVA)], and quality of life assessments.

Safety evaluations will include adverse events, concomitant medications, physical exam, vital signs, and clinical laboratory testing.

Following the initial 4 infusions, all subjects will be eligible to participate in a 12-month open label extended assessment period and receive up to 4 additional IV infusions of CAP-1002 once every 3 months. An analysis of extended safety and efficacy will be conducted after all subjects have completed the Month 24 visit.

Eligibility

You can join if…

Open to males ages 10 years and up

  1. Male subjects at least 10 years of age at time of consent who are willing and able to provide informed consent to participate in the trial and diagnosed with DMD as confirmed by the Investigator
  2. Genetically confirmed DMD
  3. Performance of the Upper Limb test (PUL) entry item scores 2-6 and total PUL score less than or equal to 40. Enrollment of patients with PUL entry score 6, Exon 44 skipping amenable, and/or Exon 3 through 7 deletions will be capped at no more than 10% of the total study population.
  4. Reduced ability to walk/run (if ambulatory): subjects must take more than 10 seconds for the 10-meter walk/run (i.e., velocity < 1 meter/second)
  5. If non-ambulatory, loss of independent ambulation between 10th and 18th year birthday
  6. Treatment with systemic glucocorticoids for at least 12 months and at a stable dose at least 6 months prior to study participation, except for weight-based or toxicity-related adjustments
  7. Current and up-to-date immunizations
  8. Adequate venous access for parenteral IP infusions and routine blood collection
  9. Assessed by the Investigator as willing and able to comply with the requirements of the trial

    10. Sexually active subjects and their partners who are fertile must agree to use

    effective method(s) of contraception

You CAN'T join if...

  1. Left ventricular ejection fraction (LVEF) less than or equal to 35% prior to randomization
  2. Elbow-flexion contractures > 30° in both extremities
  3. Body mass index (BMI) > 45
  4. Percent predicted forced vital capacity (FVC%) < 35% within 6 months prior to randomization
  5. Inability to perform consistent PUL 2.0 measurement within ± 2 points without shoulder domain or within ± 3 points with shoulder domain during paired testing at screening
  6. Risk of near-term respiratory decompensation in the judgment of the Investigator, or the need for initiation of day and night non-invasive ventilator support as defined by serum bicarbonate ≥ 29 mmol/L at screening
  7. History of non DMD-related chronic respiratory disease requiring ongoing or intermittent treatment, including, but not limited to, asthma, bronchitis, and tuberculosis
  8. Acute respiratory illness within 30 days prior to screening and during screening
  9. Initiation of nocturnal non-invasive ventilation within 30 days prior to screening

    10. Planned or anticipated thoracic or spinal surgery within the 6 months following

    randomization

    11. Planned or anticipated lower extremity surgery within the 6 months following

    randomization, if ambulatory

    12. Known hypersensitivity to dimethyl sulfoxide (DMSO) or bovine products 13. Initiation of treatment with metformin or insulin within 3 months prior to

    randomization

    14. Initiation of treatment with an FDA-approved exon skipping therapy for the treatment

    of DMD and/or non-weight based adjustments within 12 months prior to randomization

    15. Treatment with human growth hormone within 3 months prior to randomization, unless on

    a stable dose allowing for weight-based dose adjustments (as determined by the site Investigator) for at least 24 months prior to randomization

    16. Treatment with a cell therapy product within 12 months prior to randomization; any

    prior exposure to CAP-1002 will be excluded

    17. Treatment with an investigational product within 6 months prior to randomization 18. History, or current use, of drugs or alcohol that could impair the ability to comply

    with participation in the trial

    19. Inability to comply with the investigational plan and follow-up visit schedule for any

    reason, in the judgment of the investigator

    20. Inability to undergo a cardiac MRI
