Title: 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~Study Design: Single arm, practice-based, feasibility study~Study Duration: Estimated duration for the main protocol (e.g. from starts of screening to last subject processed and end of the study) is approximately 18 months~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.
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.
