Study summary

The overall goal of this study is to develop mesenchymal stem cell therapy for treatment of acute spontaneous hemorrhagic stroke.

Read the detailed description

The overall clinical development strategy of this project is to conduct this Phase I dose escalation study entitled "A Pilot Study to Evaluate the Safety and Feasibility of Mesenchymal Stem Cells Therapy in Patients with Recent Intracerebral Hemorrhage". This study will be performed under this current IND application and will be limited to the proposed 12 subjects (3 IV and 1 IT dose groups).

In this application the investigators are proposing to evaluate safety and feasibility of allogeneic, bone marrow (BM) derived mesenchymal stem cells (MSC) to induce neuroregeneration, improve neurological function and alleviate inflammation.

What researchers measure

Primary outcomes

  1. Occurrence of adverse events

    Number of adverse events at each Mesenchymal Stem Cell (MSC) dose and following infusions up to one year.

    Time frame: 1 year

Secondary outcomes

  1. Changes in neurological function test

    The NIH Stroke Scale will be used to assess stroke-related neurologic deficits. A trained observer rates the patient's ability to perform tasks and answer questions. Ratings for each item are scored with 3 to 5 grades with 0 as normal.

    Time frame: Pre infusion and post-infusion days 1, 2, 3, 7, 30, 90, 180

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 21, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
