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
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.
