Have You or a Loved One Had A Stroke?

We are seeking individuals who have had a recent stroke to participate in a research study of modified stem-cell therapy for the treatment of stroke and to participate in future research studies for stroke.


You may be eligible to participate in this research study if you:

  • Are between the ages of 18 and 75 years old
  • Have suffered a stroke within the last three years
  • Have ongoing weakness as a result of the stroke
  • Are able and willing to undergo CT, MRI and PET brain scans as part of the study
  • Are able and willing to travel to Palo Alto, California; Pittsburgh, Pennsylvania; Birmingham, Alabama; Atlanta, Georgia; or Chicago, Illinois) for study-related procedures and follow-up visits

Note: Other inclusion and exclusion criteria apply.


This Phase I/IIa clinical trial designed to test the safety and efficacy of a modified stem-cell therapy that is administered directly to the injured brain through a neurosurgical procedure. Participants will have approximately eight follow-up visits for additional examinations, questionnaires, video recordings, and brain scans over the following two years. (See About the Study for additional details about this research study.)


We have developed an online eligibility questionnaire to help to see if you might be a candidate for this research study as well as future research studies for stroke. Individuals that complete this questionnaire may be contacted about this stem-cell study and future research studies for stroke.


The questionnaire includes detailed questions about your medical history and symptoms and should take about 30 minutes to complete. The study coordinators and the study sponsor will use this information to determine your initial eligibility and may contact you to obtain additional information and to tell you more about the study before you can enroll.


What Are Stem Cells?

Stem cells are cells that have the potential to develop into different types of cells within the body. The research study is investigating whether the adult stem cells developed for this study aid the injured brain and promote cell survival.

What is a Clinical Trial?

A clinical trial is a research study designed to assess the safety or efficacy of a treatment or intervention. A Phase I/IIa clinical trial is specifically focused on the safety, tolerability, and dosing requirements of a treatment.
