Could stem cells help stroke patients recover? new trial launches
NCT ID NCT07371624
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 2 times
Summary
This study tests a single injection of stem cells (B2065) given within 36 hours of a stroke. The goal is to see if it is safe and might help patients recover better. Fifty-four adults with moderate to severe stroke will receive either the stem cells or a placebo, and be followed for two years.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- B2065 (allogeneic adipose-derived mesenchymal stromal cells)
- What this could lead to
- If it works, this could point toward a treatment that helps people recover better after a stroke by reducing brain damage.
- What could go wrong
- This is an early-phase trial with only 54 participants, so it is not yet proven to work. There may be side effects like infusion reactions or other unknown risks.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria 1. Aged 18 to 75 years (inclusive of the boundary values), with no restriction on sex. 2. Patients with ischemic stroke confirmed by imaging examinations (CT/MRI). 3. Time from onset of stroke symptoms to administration of the investigational product ≤36 hours; for wake-up stroke, the time of onset is defined as the last-known-well time (the last time the patient was observed to be normal). 4. NIHSS score at screening is 8 to 20. 5. The patient or legally authorized representative is willing to participate in this trial and agrees to sign the informed consent form. Exclusion Criteria 1. Patients who have received intravenous thrombolysis and/or mechanical thrombectomy prior to dosing. 2. Modified Rankin Scale (mRS) score ≥2 before stroke onset. 3. Patients who currently have intracranial hemorrhagic diseases (e.g., intracerebral hemorrhage, epidural hematoma, subarachnoid hemorrhage, etc.), or who have brain tumors, cerebrovascular malformations, multiple sclerosis, a history of severe traumatic brain injury, encephalitis, or other conditions causing stroke-like symptoms. 4. Patients who are unable to undergo CT and/or MRI examinations. 5. Patients with decreased level of consciousness (NIHSS item 1a score ≥2). 6. Patients who may have major neurologic or psychiatric disorders that seriously interfere with the participant's compliance with trial assessments. 7. Body temperature \>38°C prior to dosing, and the investigator assesses that there is a risk of infection. 8. Patients with uncontrollable active infection; or patients who have received systemic anti-infective therapy within 7 days prior to dosing and, in the investigator's judgment, may be likely to convert to uncontrollable active infection in the short term. 9. Patients with current or prior severe diseases of other organ systems, including but not limited to: 1. Patients with severe heart failure (NYHA Class III or IV) and/or severe respiratory failure; 2. Patients with renal disease with estimated glomerular filtration rate (eGFR) \<30 mL/min/1.73 m²; 3. Advanced liver disease, such as hepatitis or liver cirrhosis; 4. Patients positive for hepatitis B surface antigen (HBsAg) and/or hepatitis B e antigen (HBeAg); patients positive for hepatitis B e antibody (HBeAb) and/or hepatitis B core antibody (HBcAb) with quantitative HBV-DNA above the upper limit of normal; patients with any of the following test results positive: hepatitis C virus antibody (HCV-Ab), Treponema pallidum antibody (TP-Ab), or human immunodeficiency virus antibody (HIV-Ab); 5. Patients with hypertension not controlled after taking therapeutic medications, with systolic blood pressure ≥185 mmHg and/or diastolic blood pressure ≥110 mmHg; 6. Blood glucose \<2.8 mmol/L (50 mg/dL) or \>22.2 mmol/L (400 mg/dL). 10. Screening laboratory tests meeting any of the following criteria: 1. Serum alanine aminotransferase (ALT) ≥3× upper limit of normal (ULN); 2. Serum aspartate aminotransferase (AST) ≥3× ULN; 3. Serum creatinine (Cr) ≥2× ULN; 4. Absolute neutrophil count (ANC) \<1.5×10\^9/L; 5. Platelet count (PLT) \<100×10\^9/L; 6. Hemoglobin (Hgb) \<90 g/L; 7. International normalized ratio (INR) \>1.7 or activated partial thromboplastin time (APTT) \>1.25× ULN. 11. Patients with malignant tumors or other diseases with an expected survival of less than 2 years. 12. Patients with other acquired or congenital immunodeficiency diseases, or those currently using immunosuppressants. 13. Patients who, upon screening inquiry, have alcohol dependence or a history of drug abuse. 14. Pregnant or breastfeeding women; or those who plan to conceive, donate sperm, or donate oocytes during the trial and/or are unwilling to take effective contraception measures. 15. Patients who participated in any other clinical trial within 1 month prior to screening. 16. Patients who are allergic to any component of the investigational product. 17. Patients deemed by the investigator to be unsuitable for participation in this trial.
