Guo Y, Yang Y, Mao Q, Liu H, Wang T, Sun F, Wu J, Cui Y. Efficacy of collagenase Clostridium histolyticum combination therapies for Peyronie's disease: a systematic review and meta-analysis. Sex Med Rev 2024; 12:497-504. [PMID: 38650382 DOI: 10.1093/sxmrev/qeae025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 02/20/2024] [Accepted: 03/29/2024] [Indexed: 04/25/2024]
Abstract
INTRODUCTION Peyronie's disease (PD) is a common penile disorder characterized by the formation of fibrous noncompliant hard nodules in the tunica albuginea of the penis. Collagenase Clostridium histolyticum (CCH) is an injectable drug that treats PD by enzymatically degrading plaque interstitial collagen. CCH has been used in patients with varying curvature, as well as in the acute and stable phases of the disease, through a variety of treatment regimens and combinations. We carried out a systematic review and meta-analysis to assess the efficacy of CCH combination therapies for PD. METHODS We selected 4 observational comparative studies and 3 randomized controlled trials including 532 participants from the PubMed, Embase, and Cochrane databases (until December 2023) to evaluate the efficacy of CCH combination therapies for PD. The primary outcome was clinical efficacy as evaluated by improvement in penile curvature and penile length, as well as by scores on the Peyronie's Disease Questionnaire (PDQ) for symptom bother, penile pain, and psychological symptoms. Continuous data were represented by mean difference (MD) and 95% CI. All data were analyzed by Review Manager version 5.3. RESULTS For penile length (MD, 0.81 cm; 95% CI, 0.17-1.45; P = .01), PDQ symptom bother (MD, -1.02; 95% CI, -1.83 to -0.21; P = .01), and PDQ penile pain (MD, -0.93; 95% CI, -1.50 to -0.36; P = .001), CCH combination therapy showed significantly greater improvements vs CCH monotherapy. However, in the other indicators, penile curvature and PDQ psychological symptoms, there was no significant difference between the therapies. CONCLUSION This meta-analysis supports that CCH combination therapies can partially increase penile length and ameliorate symptom bother and penile pain to some extent. However, CCH combination therapies still need to be evaluated through more high-quality research.

Tissue anisotropy and collagenomics in porcine penile tunica albuginea: Implications for penile structure-function relationships and tissue engineering. Acta Biomater 2023; 169:130-137. [PMID: 37579910 DOI: 10.1016/j.actbio.2023.08.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Revised: 08/02/2023] [Accepted: 08/09/2023] [Indexed: 08/16/2023]
Abstract
The tunica albuginea (TA) of the penis is an elastic layer that serves a structural role in penile erection. Disorders affecting the TA cause pain, deformity, and erectile dysfunction. There is a substantial clinical need for engineered replacements of TA, but data are scarce on the material properties and biochemical composition of healthy TA. The objective of this study was to assess tissue organization, protein content, and mechanical properties of porcine TA to establish structure-function relationships and design criteria for tissue engineering efforts. TA was isolated from six pigs and subjected to histomorphometry, quantification of collagen content and pyridinoline crosslinks, bottom-up proteomics, and tensile mechanical testing. Collagen was 20 ± 2%/wet weight (WW) and 53 ± 4%/dry weight (DW). Pyridinoline content was 426 ±131 ng/mg WW, 1011 ± 190 ng/mg DW, and 45 ± 8 mmol/mol hydroxyproline. Bottom-up proteomics identified 14 proteins with an abundance of >0.1% of total protein. The most abundant collagen subtype was type I, representing 95.5 ± 1.5% of the total protein in the samples. Collagen types III, XII, and VI were quantified at 1.7 ± 1.0%, 0.8 ± 0.2%, and 0.4 ± 0.2%, respectively. Tensile testing revealed anisotropy: Young's modulus was significantly higher longitudinally than circumferentially (60 ± 18 MPa vs. 8 ± 5 MPa, p < 0.01), as was ultimate tensile strength (16 ± 4 MPa vs. 3 ± 3 MPa, p < 0.01). Taken together, the tissue mechanical and compositional data obtained in this study provide important benchmarks for the development of TA biomaterials. STATEMENT OF SIGNIFICANCE: The tunica albuginea of the penis serves an important structural role in physiologic penile erection. This tissue can become damaged by disease or trauma, leading to pain and deformity. Treatment options are limited. Little is known about the precise biochemical composition and biomechanical properties of healthy tunica albuginea. In this study, we characterize the tissue using proteomic analysis and tensile testing to establish design parameters for future tissue engineering efforts. To our knowledge, this is the first study to quantify tissue anisotropy and to use bottom-up proteomics to characterize the composition of penile tunica albuginea.

Abstract
Peyronie's disease treatments is changing again due the interruption of Xiapex® distrubution in Europe. There are many reasons that can be referred to this event. In this editorial we would like to shed light on the current cost items relating to treatment with collagenase clostridium histolyticum (CCH). The inaccessibility of the drug has seen both an increase in surgery for the treatments of both PD and Dupuytren's disease and an interruption of therapies in patients who had not completed their therapeutic cycle. Considering the aforementioned concerns, we would like to invite researchers dealing with PD to conduct studies with the available CCH products in collaboration with the drug companies in order to give again an efficacious treatment for PD.

The efficacy and safety of intralesional injection of collagenase Clostridium histolyticum for Peyronie’s disease: A meta-analysis of published prospective studies. Front Pharmacol 2022; 13:973394. [DOI: 10.3389/fphar.2022.973394] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 09/12/2022] [Indexed: 11/13/2022] Open
Abstract
Background: Peyronie’s disease (PD) is a progressive fibrotic disorder of the penis that is adverse to men’s health. Currently, effective and reliable non-surgical options for PD are limited. Since the Food and Drug Administration (FDA) approved it in 2013, intralesional injection of collagenase Clostridium histolyticum (CCH) became the only licensed treatment for PD. This meta-analysis aims to evaluate the clinical efficacy and safety of CCH in treating PD, predominantly based on post-FDA studies.Methods: The primary outcome was clinical efficacy evaluated by the percentages of improvement in penile curvature (PC) and Peyronie’s disease symptom bother score (PD bother score). The secondary outcome was the safety assessed by treatment-related adverse events (TRAEs). Heterogeneity was assessed by Cochran’s Q and I2 tests. Sensitivity and subgroup analyses were performed to explore the source of heterogeneity. Funnel plots and Egger’s test were used to evaluate the publication bias.Results: A total of 11 studies with 1,480 intentions to treat (ITT) population were included. The pooled effect of the improvement of PC was 35% (95% CI: 0.33–0.38), and the pooled improvement of the PD bother score was 41% (95% CI: 0.37–0.45). No heterogeneity was found at the pooled improvement of PC (p = 0.845, I2 = 0.00%). Meanwhile, some heterogeneity existed in the pooled improvement of the PD bother score (p = 0.069, I2 = 43.4%). The pooled effect of TRAEs was 93% (95% CI 0.88–0.97) with significant heterogeneity (p < 0.000, I2 = 92.3%).Conclusion: The intralesional injection of CCH could significantly improve the penile deformity of PD patients. Meanwhile, CCH appears to ameliorate the PD bother score to some extent and has acceptable clinical safety. Future studies are required to clarify the long-term outcomes of CCH injection in the treatment of PD.

Abstract
BACKGROUND Collagenase Clostridium histolyticum (CCH), which was approved by the FDA for the treatment of Peyronie's disease (PD) in 2013, may obviate the need for surgery but its historically high cost must be considered when offering CCH vs surgical intervention to affected patients. AIM To compare trends of intralesional injections vs surgical treatment for PD and assess the contemporary cost of treatment with CCH vs surgical intervention. METHODS We reviewed 2009-2019 MarketScan Commercial Claims data to identify all men 18 years and older with PD. CPT and HCPCS codes were used to identify PD treatments for each patient. Associated insurance claims in USD were summed for each treatment type. OUTCOMES Total and out-of-pocket costs, as well as frequencies, for treatments were calculated on a yearly basis and the Cochran-Armitage test was used to compare frequencies before and after FDA approval of CCH. RESULTS Of 89,205 men diagnosed with PD, 21,605 (24.2%) underwent treatment; most required only intralesional injections, however 1,519 (7.0%) received only surgical therapy and 1,951 (9.0%) required medical and surgical therapy. Intralesional CCH use sharply increased after its FDA-approval in 2013 with a concomitant fall of intralesional verapamil use. The use of both surgical plication and plaque grafting decreased steadily from 2009 to 2019. The median cost per patient for all 3 treatments increased over the study time-period: $1,856 to $3,196 for plication, $2,233 to $3,631 for plaque grafting, and $6,940 to $8,895 per cycle for CCH. Out-of-pocket median patient contribution for plication, plaque grafting, and per cycle intralesional CCH injection were similar over the study period and never exceeded $300. CLINICAL IMPLICATIONS CCH is significantly more expensive than any surgical treatment option, however, the out-of-pocket patient contribution for surgery and CCH are similar. STRENGTHS & LIMITATIONS This study incorporated all procedure costs and is the most contemporary, comprehensive, and accurate reflection of overall and out-of-pocket costs to patients for surgical and intralesional PD therapies. We anticipate these data to allow for a more complete discussion between patients and providers regarding their care. The use of a commercial claims database prohibited assessment of post-procedural costs and treatment outcomes. CONCLUSION CCH use has increased significantly since its FDA approval in 2013 with out-of-pocket patient contribution comparable to surgical therapy despite significantly higher total treatment costs.

Abstract
A variety of devices are available for the management of patients with erectile dysfunction, Peyronie's disease, penile dysmorphophobia, for support before and after penile prosthesis insertion, and after radical prostatectomy. Traction devices include, but are not limited to, Penimaster PRO (MSP Concept, Berlin, Germany), Andropenis and Andropeyronie (Andromedical, Madrid, Spain), and the Restorex (PathRight Medical, Plymouth, USA). The other type of devices are vacuum devices such the Osbon ErecAid (Timm Medical, MN, USA). Different devices are optimal for different clinical applications, and robust and contemporary clinical data show a variety of strengths and weaknesses for each device. Research currently favours the use of traction devices for improvement of penile curvature and erectile function in patients with Peyronie's disease compared with vacuum devices; Penimaster Pro and Restorex have been shown to be associated with the best outcomes in this indication. Vacuum devices are favoured for treatment of erectile dysfunction and penile length loss after radical prostatectomy; the Osbon ErecAid is the most well-studied device for this indication. Research into other uses of vacuum and traction devices, such as for penile dysmorphophobia or before and after penile prosthesis, is very limited. Compliance, cost and availability remain substantial challenges, and further high-quality evidence is required to clarify the role of traction devices in urology and sexual medicine.

Abstract
INTRODUCTION Penile traction therapy (PTT) aims to non-surgically reduce curvature, enhance girth, and recover lost length. Available clinical practice guidelines however lack clear recommendations regarding their use. AIM To present a comprehensive review and recommendation regarding the available evidence to the use of PTT in Peyronie's disease (PD). METHODS A systematic literature search was performed on Pubmed and Medline for relevant studies from all times until 2019. Studies of PTT (monotherapy and in combination) in patients with PD with any documented degree of curvature and in either the acute or chronic phase of the disease were included. Full texts not published in English language were excluded. MAIN OUTCOMES MEASURES Several scenarios, including preclinical data have been investigated. For each topic covered evidence was analyzed and expert opinion was stated. RESULTS The paucity of high-level studies precluded any strong recommendations, however, specific statements on this topic, summarizing the ESSM position, were provided. The available data about the use of PTT in PD are still poor, and the impact of this therapy for the treatment of PD has not been clearly stablished. Available data in the clinical setting are still poor, and the impact of these devices on PD evolution has not been clearly established. CONCLUSION PTT seems to be a valid treatment option for PD, although there is not enough evidence to give any definitive recommendation in any clinical scenario.

Abstract
Peyronie’s disease (PD) is a localized fibrotic lesion of the penis that has adverse effects on men’s health. In this review, we summarized the molecular mechanisms and pharmacotherapies of PD. A literature search was conducted using PubMed and Cochrane Library during 2001–2020. Although no oral or topical medication demonstrated efficacy in monotherapy of PD, several intralesional medications have yielded promising results. Currently, the effective strategy in management of PD should be combined modality therapy, including but not limited to pharmacotherapy, mechanical therapy, and psychotherapy. Meanwhile, basic research is still necessary to facilitate the development of novel and more reliable treatments. In future, more attention should be given simultaneously to epigenetic changes, inflammatory cytokines, the abnormal wound-healing process, and profibrotic and anti-fibrotic factors to provide more options for this refractory disease.

Abstract
BACKGROUND It is currently unclear if men with Peyronie's Disease (PD) who achieve minimal benefits with the first 2 series of Collagenase Clostridium Histolyticum (CCH) injections should continue with additional injections. AIM To analyze curvature improvements from the final two series of CCH injections based on amount of improvement during the first 2 series. METHODS A prospective registry was analyzed of all men undergoing CCH injections for PD at a single institution. Men were included if they had completed a full 4 series (8 injections) of CCH and had baseline, interval (after 2 series), and/or final (after 4 series) curvature assessments available. Men were stratified into cohorts using baseline-to-interval assessments of ≤10° (or ≤20%) and >10° (or >20%), and improvements were compared using interval-to-final assessments. OUTCOMES The primary outcome was interval-to-final curvature improvements stratified by ≤10°/>10° or ≤20%/>20% improvements achieved during the baseline-to-interval period. Secondary outcomes included analyses of demographic and pathophysiologic variables to determine associations with significant improvements during the final 2 CCH series. RESULTS A total of 296 PD men were identified as receiving at least one CCH injection, of whom 175 had baseline-to-interval, 84 interval-to-final, and 115 with baseline-to-final measurements. Mean age was 56.6, PD duration 28.6 months, baseline curvature 63.4°, hourglass deformity 36.2%, and calcification 20%. Mean overall curve improvement was -21.5° (33.1%). Among men who experienced ≤20% improvements after 2 series, the mean subsequent curvature change was -24.6% during the final two series (vs +4.3% of those with >20% initial improvement, P< .001), and they were 2.7x more likely to experience >20% subsequent curve improvements. Thirty-one percent of those who achieved >10° during the first 2 series experienced benefits during the final 2 series compared to 70% of men who had ≤10° improvement initially. No demographic or pathophysiological variables predicted likelihood for improvements during the final 2 series of injections. CLINICAL IMPLICATIONS Men who fail to achieve significant benefits with 2 series of CCH injections may benefit from completing the final 2 series. STRENGTHS AND LIMITATIONS Strengths including a relatively large, prospective series. Limitations include a single center, nonrandomization, nonblinded assessments, and restriction to men who completed eight injections. CONCLUSIONS In the current series, approximately 2/3 of men who fail to achieve >10° or 20% curve improvements with an initial 2 series of CCH injections achieved >10° or 20% improvements with the subsequent 2 series.

Abstract
PURPOSE OF REVIEW To analyze the literature on current conservative treatment options for Peyronie's disease (PD). RECENT FINDINGS Conservative therapy with intralesional collagenase clostridium histolyticum (CCH) is safe and efficacious in either the acute or chronic phases of PD. Combination treatment with penile traction therapy (PTT) can produce even better results. While most PTT devices require extended periods of therapy up to 8 h per day, the RestoreX® device can be effective at 30-90 min per day. A variety of conservative therapies are available for treatment of PD. The available literature does not reveal any treatment benefit of oral therapies. Intralesional therapy is the mainstay conservative treatment of PD. Intralesional CCH therapy is the first Food and Drug Administration-approved intralesional therapy and represents the authors' preference for medical therapy. The most effective conservative management of PD likely requires a combination of therapies.

Abstract
Peyronie's Disease is an incurable condition of the tunica albuginea of the penis associated with scarring, plaque formation, and penile deformity on erection. It is often associated with erectile dysfunction. Recent data have supported a familial and genetic predisposition to this chronic condition. The etiology of Peyronie's Disease is unknown, but is likely associated with multiple micro traumas to the erect penis in men who are susceptible to the scarring typical of Peyronie's Disease. The treatment of Peyronie's Disease has improved over the past decade as a result of animal studies and the approval of new medications. In the acute phase of the condition, phosphodiesterase type 5 inhibitors have been shown to have some benefit and are supported by animal studies demonstrating reduced fibrosis of the penis in animal models of Peyronie's Disease. In the stable phase of the disease, newer injectable agents have shown great promise. Collagenase clostridium histolyticum is approved for the treatment of Peyronie's plaques by direct injection into the scarred tissue with data showing satisfactory safety and efficacy. Surgical procedures for penile straightening have been refined with improved outcomes in the past decade. For those men with erectile dysfunction and Peyronie's Disease, penile implants can restore erectile function and form. As a result of the new understanding of the risk factors for Peyronie's Disease and recent advances in treatment options, the algorithm for the treatment of Peyronie's Disease has improved outcomes for patients and their partners.

Abstract
Peyronie's disease (PD)-related penile deformity is managed with multiple treatment modalities including oral medications, intralesional injections, and surgery. Penile traction therapy (PTT) is one such modality with purported benefits, albeit with notable differences in the characteristics of available traction devices and published study protocols. We provide a comprehensive review of the available data supporting PTT for PD treatment. We performed a rigorous database search to identify all studies pertaining to PTT for the treatment of PD through November 2019. Seventeen trials explored use of PTT as monotherapy or in combination with surgical or nonsurgical treatment, using over five different commercially available devices. All devices were well tolerated, although compliance and daily duration of use were highly variable. PTT resulted in variable improvements in stretched penile length and penile curvature, depending on study protocol, patient population, and device. PTT appears to be a safe and well-tolerated treatment for PD as monotherapy or in combination with other nonsurgical and surgical treatments, and for men in both the acute and chronic phases. Further studies are needed to compare available devices, evaluate device characteristics associated with treatment success, differentiate outcomes in acute vs. chronic PD populations, and determine the optimal duration of use.
