Early postinterventional clinical implications of Collagenase Clostridium Histolyticum injection versus limited fasciectomy for Dupuytren's disease. (PubMed, J Hand Microsurg) - "The results of this study suggest that CCH injections lead to less complicated wound healing requiring less intensive surgeon and hand therapy aftercare than LF. CCH represents a valuable addition to Dupuytren's disease treatment, allowing for repeated use in severe, complex, or recurrent cases without increasing procedure-related risks while offering versatility for combination with minimally invasive surgery."

Outcomes of limited fasciectomy, needle fasciotomy and collagenase injection for Dupuytren's disease: a systematic review and meta-analysis of individual patient data. (PubMed, J Hand Surg Eur Vol) - "This systematic review and meta-analysis of individual patient data evaluates the outcomes of treatment for Dupuytren's disease using limited fasciectomy (LF), percutaneous needle fasciotomy (PNF) and collagenase clostridium histolyticum (CCH) injection...Overall, the clinically relevant contracture correction was comparable between LF, PNF and CCH, but CCH had a higher risk of minor complications and LF had the longest time to recurrence. Treatment decisions should consider the trade-off between complications and recurrence risk."

The Impact of Emerging Therapies and Declining Physician Reimbursement on Dupuytren Disease Treatment: A 21-Year Review. (PubMed, J Hand Surg Am) - "The growing use of CCH as the dominant treatment for DC underscores how marketing and public awareness may influence treatment practices. Physicians have a responsibility to understand these influences, ensuring that treatment decisions are guided by clinical efficacy and cost-effectiveness while managing patient expectations and prioritizing long-term outcomes over trends driven by marketing."

Outcomes and management of Peyronie's disease with combined treatment of collagenase clostridium histolyticum, vacuum erection device, and tadalafil. (PubMed, Asian J Androl) - "Minor complications were observed in 15 patients, while 13 were dissatisfied with treatment, with six opting for surgery. The modified protocol demonstrated significant improvements in penile curvature and erectile function with minimal complications, offering a safe, cost-effective alternative to traditional intensive treatments."

Are patients undergoing intralesional collagenase Clostridium histolyticum injection therapy for Peyronie's disease compliant? A 7-year analysis from a tertiary care men's health center. (PubMed, J Sex Med) - "Overall compliance rate for CCH injection therapy was 70.89%. Greater curvature reduction was demonstrated in compliant patients. Common reasons for incomplete treatment included adverse effects (15.1%), early satisfaction with results (14.1%), and unknown factors (45.4%). However, missing data and bias from retrospective design are major limitations."

Response to Intralesional Collagenase Clostridium Histolyticum in Peyronie's Disease Patients with Concomitant Dupuytren's Contractures (AUA 2025) - "This study provides the first robust evidence that concomitant DC is associated with a superior response to CCH therapy in PD patients. The significantly greater curvature correction in the DC group suggests a potential synergistic effect of DC on CCH efficacy, meriting further investigation. These findings could influence clinical decision-making and patient counseling for men with PD and concurrent DC."

Efficacy of a Novel Collagenase Clostridium Histolyticum Protocol for Peyronie's Disease Among Prior Non-responders: A Randomized, Controlled, Single-Blinded Study (AUA 2025) - P4 | "Men were randomized 3:1 to receive either CCH+traction (RestoreX)+sildenafil (treatment) up front or initial observation followed by treatment (controls). Repeating CCH using a novel protocol after an initially unsuccessful course of CCH achieves significant improvements in curvature and patient satisfaction. Additional data, including external validation, are warranted."

Peyronie's disease outcomes following collagenase clostridium histolyticum may not differ by sexual orientation. (AUA 2025) - "In this series, patients who identified as MSM were with significantly higher rates of penile fracture following CCH. However, rates of complications requiring intervention, treatment satisfaction, and change in penile curvature were not statistically different in this population. While further work is needed to examine the use of CCH in this population, this data suggests that CCH may be used safely and with similar expected outcomes in the population of MSM."

Comparative outcomes of intralesional collagenase injection for Peyronie's disease: acute vs. stable phase treatment. (PubMed, Int J Impot Res) - "Collagenase clostridium histolyticum (CCH) was FDA-approved for treating Peyronie's Disease (PD), demonstrating significant curvature improvement in patients during the stable phase of disease...A total of 55 patients (76.39%) in the stable phase and 23 patients (82.14%) in the acute phase showed improvement in curvature, with no significant differences in curvature outcomes or adverse events between the two groups. This study contributes to the growing evidence that intralesional CCH treatment during the acute phase of PD is safe and effective."

Analyzing the Impact of Collagenase Clostridium Histolyticum on Treatment Patterns and Social Deprivation Trends in Dupuytren's Contracture (AAOS 2025) - "Across different levels of social deprivation from 2013 to 2021, there was a notable variation in the utilizatio n patterns of treatments for Dupuytren's contracture, particularly an increase in fasciectomy use in communities with low social deprivation. This difference in practice among surgeons likely depended on several factors, some may include the socioeconomic status of patients and the available resources within the practice's zip code area. Previous literature analyzing provider trends before 2015 speculated that CCH would surpass surgical fasciectomy in utilization (Thayer et al., 2018)."
