Primary Outcome Measures:
  • Biopsy Procedure-related Adverse Events [ Time Frame: at biopsy or between biopsy and treatment ] [ Designated as safety issue: Yes ]

    Biopsy was required to generate AMDC products. Biopsy procedure-related events were defined as systemic responses to the biopsy procedure or injury at the biopsy site.

    Three patients experienced 7 biopsy procedure-related events. All biopsy procedure-related events either self-resolved or were easily treated.

  • Injection Procedure-related Adverse Events [ Time Frame: 30 days ] [ Designated as safety issue: Yes ]

    AMDC treatment was administered via intrasphincteric injection. Injection procedure-related events were defined as systemic responses to the injection procedure or genitourinary events occurring within 30 days of the injection procedure that could be attributed to cystoscopy or catheterization.

    8 patients experienced 14 injection procedure-related events. All injection procedure-related events were self-resolved or easily treated.

  • AMDC Product-related Adverse Events [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]

    If an immune response after injection or any urinary retention occurred and seemed suspicious, the physicians were consulted to determine whether the effect was likely related to the AMDC product.

    No adverse events reported during the study were adjudicated as AMDC product-related.
