Outcome Measures

Primary Outcomes (4)

  • Tumor Marker Levels

    Long-term safety will be evaluated by assessing changes in tumor marker levels including prostate-specific antigen (PSA), alpha-fetoprotein (AFP), and carcinoembryonic antigen (CEA) during the safety follow-up period.

    Baseline and annually for up to 5 years after enrollment in the long-term follow-up study.

  • Serious Adverse Events

    The number of participants experiencing serious adverse events during the safety follow-up period.

    From enrollment in the long-term follow-up study through 5 years of follow-up.

  • New Cancer Development

    The number of participants with newly diagnosed malignancies during the safety follow-up period.

    From enrollment in the long-term follow-up study through 5 years of follow-up.

  • Prostate Cancer Recurrence

    The number of participants with recurrence of prostate cancer during the safety follow-up period.

    From enrollment in the long-term follow-up study through 5 years of follow-up.

Study Arms (1)

Cellgram-ED Safety Follow-up Group

Participants in this arm previously received Cellgram-ED (autologous bone marrow-derived mesenchymal stem cells) via intracavernous injection in the parent phase II clinical trial. This safety follow-up study monitors these participants for long-term safety outcomes for up to 4 years (±30 days) from the completion of the parent trial, including assessment of adverse events and other clinically relevant safety parameters.

Eligibility Criteria

Age19 Years - 80 Years
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

This observational study includes patients who previously participated in the Phase 2 clinical trial of Cellgram-ED and received the investigational cell therapy. Eligible participants are those who completed the interventional study and provided written informed consent for long-term safety follow-up. No additional investigational treatment is administered as part of this study; data are collected solely for the assessment of long-term safety outcomes.

You may qualify if:

  • Participants who previously participated in the parent clinical trial and received the cell therapy (Cellgram-ED).
  • Participants who have provided written informed consent to participate in this safety follow-up study.
