Efficacy and Safety of Stempeucel® in Patients With Critical Limb Ischemia (CLI) Due to Buerger's Disease

September 8, 2025 updated by: Cell Biopeutics Resources Sdn Bhd

An Observational, Practice-Based, Open Label, Feasibility Study to Observe the Efficacy and Safety of Intramuscular Administration of Stempeucel® in Malaysian Patients With Critical Limb Ischemia (CLI) Due to Buerger's Disease

The goal of this observational, practice-based feasibility study is to observe the efficacy and safety of intramuscular administration of Stempeucel® in Malaysian patients with critical limb ischemia (CLI) due to Buerger's disease. The main questions it aims to answer are:

  • Can intramuscular administration of Stempeucel® reduce symptoms of CLI due to Buerger's disease while improving the healing rate and functional outcomes?
  • Does intramuscular administration of Stempeucel® causes any serious adverse events in CLI due to Buerger's disease patients? Study patients will be assessed by the PI before administering the Stempeucel® for any other organ with inflammation. The study patients will also be followed up to the duration of 1 year after study treatment administration for safety and efficacy assessment.

Study Center: Universiti Kebangsaan Malaysia Medical Centre (UKMMMC), Jalan Yaacob Latif, Bandar Tun Razak, 56000 Kuala Lumpur, Wilayah Persekutuan, Malaysia

Objectives: To observe the efficacy and safety of Stempeucel® (adult human bone marrow-derived, cultured, pooled, allogeneic mesenchymal stromal cells) in Malaysian patients with critical limb ischemia (CLI) due to Buerger's disease.

Investigational Medicinal Product

Description

• Ex-vivo cultured allogeneic mesenchymal stem cells (MSCs) supplied in cryo-bags consisting of 150 or 200 million, suspended in 50 ml of Plasmalyte A containing 1.5% human serum albumin (HSA) and 3% dimethyl sulfoxide (DMSO).

Dosage • Dosing of Stempeucel® is based on body weight. The recommended dose is 2 million cells/kg body weight.

Administration

• 40 - 60 injections administered as 0.6 ml/kg (200 million bag) or 0.8 ml/kg (150 million bag) intramuscularly into different points on the muscle. Additional injections of 2 ml (200 million bag) or 3 ml (150 million bag) administered around the ulcer

Number of Subjects 3 patients

Data Analysis

Data Management:

  • Electronic case record form (eCRF) will be used for data entry.
  • Oracle clinical (or other suitable alternatives with audit trail) will be used for data management.

Statistical Method:

  • The SPSS® package (IBM Inc., USA, version 22) will be used for statistical evaluation.
  • All patients in the study with relevant efficacy and safety data will be considered for the analysis.
  • Efficacy analysis will be done using GEE (Generalized Estimating Equations) method or paired t test as appropriate.
  • Adverse events monitored using information voluntarily disclosed by the patients and as observed by the PI will be summarized descriptively by total number of AE(s).
  • AEs will be categorized as: all AEs, all treatment-emergent AEs, all severe AEs, treatment-related AEs and severe treatment-related AEs. These events will be reported as appropriate and summarized.
