About this study
Bone marrow MSCs will be isolated from allogenic donors, expanded under hypoxic conditions using medium containing no serum or animal-derived reagents, and applies for Phase Ⅰ/Ⅱ study in treating 18 recipients with ischemic limb diseases.
Read the detailed description
Ischemic limb disease remains one of the major causes of morbidity and mortality in the industrialized world despite the development of several new therapeutic modalities. Based on experimental data demonstrating that infusion or injection of stem/progenitor cells enhances blood flow in models of cardiovascular diseases, clinical trials were initiated in 2001 to treat patients with critical limb ischemia or cardiac ischemia with circulating blood or bone marrow-derived cells. Despite all promises, pending uncertainties and practical limitations attenuate the therapeutic use of stem/progenitor cells for ischemic limb disease. The main theme and method in the current program project, based on expertise, track record, and preliminary results of PI's laboratory, is to focus on clinical studies of using allogenic mesenchymal stem cells (MSCs), expanded under hypoxic conditions (1% O2), in treating ischemic limbs. This project is an integrated and coordinated effort aimed to overcome the regulation of cell product, and the barriers of preclinical and clinical studies. For the purposes, we have specially set up the core laboratory for stem/progenitor cells production and quality control in Cell Therapy Clean Room on the 9th floor of Medical Science Technology Building in Taipei Veterans General Hospital. We have also completed the preclinical studies in using allogenic hypoxic mouse MSCs in treating limb ischemia. In the current project, bone marrow MSCs will be isolated from allogenic donors, expanded under hypoxic conditions using medium containing no serum or animal-derived reagents, and applies for Phase Ⅰ/Ⅱ study in treating 18 recipients with ischemic limb diseases in three years.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Allogenic MSC and Normal saline in people with Critical Limb Ischemia, run by Taiwan Bio Therapeutics Inc. at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse events (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Aug 2021.
