NCT06649539

Brief Summary

Our team has previously demonstrated efficacy in performing a novel collagenase Clostridium histolyticum (CCH) injection protocol in men who previously failed to achieve a response to an initial 4 series of CCH. The objective of the current study is to evaluate a protocol that incorporates limited in-office modeling for up to 4 series, followed by up to 2 additional salvage series to determine safety and efficacy compared to historical data. Participants will receive up to 4 series of CCH injections using our previously published protocol, with mild in-office modeling. CCH injections are given on back-to back days, after which they are counseled to utilize Restorex and sildenafil daily, as instructed. Patients will undergo mild in-office modeling on day 2. The sexual partners of study participants will also be invited to enroll in the study and will complete non-validated questionnaires detailing their level of support for the patient's treatment.

Outcome Measures

Primary Outcomes (2)

  • Penile Curvature

    Compare penile curvature between baseline and post-treatment in men 1 year after completing the final injection series. A goniometer (protractor) will be used to measure from the penile angulation during a full erection in two planes (dorsal/ventral and lateral). Measurements will be in degrees.

    1 year

  • Penile Length

    Compare penile length between baseline and post-treatment in men 1 year after completing the final injection series. Measurements will be performed using a ruler, with measurements obtained from the pubic symphysis to the corona of the glans penis (measured in cm).

    1 year

Secondary Outcomes (9)

Study Arms (1)

Primary Cohort

EXPERIMENTAL

Men would receive 4 series of CCH injections: * Administered on back-to-back days * 0.9 mg administered with each series, diluted to 0.8 mL * Mild in-office modeling performed on treatment day 2 of each series * Wraps applied 2-4 full-time and 2-4 part-time days * Sildenafil 25 mg nightly and Restorex beginning treatment day 2 (sildenafil) or 3 (Restorex - 30 min/day) until 6 weeks after final injection of the final series. Note that men may stop sooner if they are satisfied before completing the 4 series. If the patient is not satisfied with outcomes by the end of the 4th series, they would be permitted to enter the 'salvage' phase of the treatment protocol. * Performed 9-12 months after the 4th series of injections. * The technique would incorporate more aggressive, in-office modeling. * Men would receive up to two additional series per this protocol.

Drug: Collagenase Clostridium HistolyticumDevice: RestoreXDrug: Sildenafil

Interventions

4 Series given to each participant, 6 weeks apart. Medication administered on back-to-back days. If failing to achieve an adequate response, men may receive up to 2 additional series 9-12 months after the 4th series. Total of 0.9 mg administered with each series, diluted to 0.8 mL

Also known as: Xiaflex, CCH
Primary Cohort
RestoreXDEVICE

Restorex initiated beginning on post-injection day 3 or as soon as tolerated - 30 min daily, continuing until 6 weeks after final injection of the final CCH series.

Primary Cohort

Men will be prescribed sildenafil 25 mg nightly beginning treatment day 2 until 6 weeks after final injection of the final series.
