MSC Secretome Therapy for Cognitive Recovery After Subacute Ischemic Stroke

23. července 2026 aktualizováno: Jumraini Tammasse

Efficacy of Mesenchymal Stem Cell Secretome Therapy on Cognitive Recovery in Patients With Subacute Ischemic Stroke: A Pilot Randomized Controlled Trial Using qEEG, BDNF, and Interleukin-1β Evaluation

Post-stroke cognitive impairment can limit rehabilitation, independence, and quality of life after ischemic stroke. This pilot randomized controlled trial evaluates whether mesenchymal stem cell-derived secretome, given in addition to standard stroke care and rehabilitation, improves cognitive recovery in patients with subacute ischemic stroke. Participants aged 40 to 75 years with ischemic stroke occurring 7 days to 3 months previously and mild-to-moderate cognitive impairment will be randomly assigned in a 1:1 ratio to receive standard care and rehabilitation plus MSC secretome or standard care and rehabilitation without MSC secretome. The primary outcome is the change in the Indonesian version of the Montreal Cognitive Assessment score. Secondary outcomes include quantitative electroencephalography parameters, serum brain-derived neurotrophic factor, serum interleukin-1β, NIHSS, modified Rankin Scale, and adverse events.

Detailní popis

This study is a pilot, parallel-group, randomized controlled trial with blinded outcome assessment. The study population consists of patients aged 40 to 75 years with clinically and radiologically confirmed subacute ischemic stroke, defined as 7 days to 3 months after stroke onset. Eligible participants must be hemodynamically stable, able to undergo a basic neuropsychological assessment, and have mild-to-moderate cognitive impairment based on the Indonesian version of the Montreal Cognitive Assessment.

Participants will be randomized in a 1:1 ratio using block randomization with allocation concealment. The intervention group will receive standard stroke care and rehabilitation plus umbilical cord mesenchymal stem cell-derived secretome. The control group will receive standard medical treatment and standardized stroke rehabilitation without MSC secretome. Outcome assessors will remain unaware of treatment allocation.

Baseline assessments include demographic and vascular risk factor data, NIHSS, modified Rankin Scale, MoCA-Ina, quantitative electroencephalography, serum brain-derived neurotrophic factor, and serum interleukin-1β. Follow-up assessments will include cognitive, neurological, functional, electrophysiological, biomarker, and safety evaluations at the prespecified study visits.

The primary outcome is the change in MoCA-Ina total score from baseline to week 8. Secondary outcomes include changes in delta-to-alpha ratio, delta-theta-to-alpha-beta ratio, relative alpha power, relative theta power, serum BDNF, serum IL-1β, NIHSS, modified Rankin Scale, and the incidence of adverse events. The primary analysis will follow the intention-to-treat principle, with per-protocol analysis as an additional analysis.

Experimentální: MSC Secretome Plus Standard of Care
Participants receive standard medical treatment and standardized stroke rehabilitation plus umbilical cord mesenchymal stem cell-derived secretome. The secretome intervention is administered according to the study protocol, with safety monitoring during and after administration.
Umbilical cord mesenchymal stem cell-derived secretome is administered in addition to standard medical treatment and standardized stroke rehabilitation. The intervention is administered twice, on day 1 and day 8, according to the investigational product protocol. Participants are monitored during and after administration for hypersensitivity reactions, fever, and other adverse events.
