Study Details

Study Description

Brief Summary

This study is an investigator initiated first-in-human interventional open label phase 1/2a clinical trial investigating an ATMP in the orphan disease LGMD to evaluate safety and efficacy.

Condition or Disease Intervention/Treatment Phase
  • Biological: GenPHSat injection (Safety)
  • Biological: GenPHSat injection (Efficacy)
  • Other: Muscle Biopsy (Safety)
Phase 1/Phase 2

Detailed Description

This trial is directed towards a first-in-human application of GenPHSats; gene edited primary human satellite cell derived muscle stem cells as a new Advanced Therapy Medicinal Product (ATMP) in a phase 1/2a clinical trial with Gene edited PHSats (GenPHSats) initiating healthy muscle development in patients with LGDM. The trial is set up to verify if GenPHSats can provide an therapy option for LGDM patients as there is currently no therapy available. The GenPHSats are an autologous product comprised of primary human satellite cell derived muscle stem cells obtained from the patient's own muscle tissue and gene edited in vitro prior to transplantation.

Arms and Interventions

Arm Intervention/Treatment
Experimental: GenPHSat safety injection and GenPHSat efficacy injection

Initial intervention with six injections into the left biceps. A second intervention with 36 injections into the right biceps.

Biological: GenPHSat injection (Safety)
Participants receive gene edited primary human muscle stem cells (GenPHsat) injection in the left biceps muscle.

Biological: GenPHSat injection (Efficacy)
Participants receive gene edited primary human muscle stem cells (GenPHsat) injection in the right biceps muscle.

Other: Muscle Biopsy (Safety)
Participants undergo muscle biopsy 3 month after safety GenPHSat injection.

Outcome Measures

Primary Outcome Measures

  1. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [Through study completion, an average of 1 year]

    Characterization of type, incidence, severity, duration, reversibility, treatability of adverse events recorded at least at visit 1, 2, 3 and 4 (end of trial).

Secondary Outcome Measures

  1. Rate of muscle biopsy post-injection structure [3 month post injection]

    The muscle biopsy taken and stained to visualize muscle biopsy structure after 3 month post injection.

Other Outcome Measures

  1. Rate of Muscle force [Until 6 month post injection]

    Muscle force measurement data taken at screening (baseline), visit 1, 2, 3 and 4 (end of trial).

  2. Rate of Blood CK [Until 6 month post injection]

    CK blood determination at screening (baseline), visit 1, 2, 3 and 4 (end of trial).
