About this study

Safety evaluations will be conducted over a period of 4 years (±30 days) from the completion date of the parent clinical trial. During the safety follow-up period, participants will be monitored for adverse events, serious adverse events, and other clinically relevant safety parameters to assess the long-term safety profile of Cellgram-ED.

Primary outcomes

  1. Tumor Marker Levels

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

    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.

  2. Serious Adverse Events

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

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

  3. New Cancer Development

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

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

  4. Prostate Cancer Recurrence

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

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