A snapshot of intralesional verapamil injection in the treatment of Peyronie's disease today

A review of Peyronie's disease insurance coverage

Background

Peyronie's disease (PD) is a fibroproliferative disorder that causes an abnormal curve of the penis resulting in pain, discomfort, and erectile dysfunction with management options including correctional surgery, penile external/internal devices, shock wave therapy (SWT), intralesional Verapamil (IV), and collagenase Clostridium histolyticum injections.

Aim

To investigate the insurance coverage of these treatment options.

Methods

The authors performed a cross-sectional analysis of the top US insurance policies for coverage of PD. Companies were chosen based on their market share and enrollment. Their policies were identified through a Web-based search and telephone interviews, and the companies' medical necessity criteria were defined. The online policies were then re-examined for interval change 3 years later.

Outcomes

There are significant discrepancies for in coverage for the different modalities of Peyronie's treatment.

Results

Of the 100 companies examined, only 54% of companies had a policy that directly addressed the treatment coverage for PD. The most covered treatment was CCH injections with 37 companies providing unanimous coverage (n = 37, 100%). Within this category, all companies required a palpable plaque as a requirement. Additionally, external/internal devices were unanimous covered by 18 companies (n = 18, 100%). Surgical treatment was covered by eight companies with six companies denying coverage (n = 8 vs. n = 6, 57.1% vs. 42.9%). IV was covered by two companies. The least covered treatment option was SWT which was universally denied by 19 companies (n = 19, 100%).

Clinical Implications

Insurance coverage of PD should be aligned with current medical literature to better increase access to care.

Strengths & Limitations

This study is limited by the updated policies of insurance companies and future applicability. Additionally, this study assumes that a written policy will provide coverage and may overestimate the actual extent of coverage. Finally, this study only addressed some of the common treatment options of PD and did not expand on all possible treatment options.

Conclusion

Differing rates for modalities of treatment may present a barrier for patients to receive individualized and adequate treatment for PD.

Current trends in non-surgical management of Peyronie's disease-A narrative review

Peyronie's disease (PD) is a connective tissue disorder affecting the tunica albuginea. It can cause pain and penile deformation, and its prevalence increases with age. Although surgery is the gold standard for the chronic phase of the disease, there are several conservative treatment methods available, and the optimal management of the acute phase of the disease remains a matter of debate. In this article, we aim to summarize the recent trends in research on the subject of non-surgical treatment of PD. The search was performed in PubMed, Scopus, and Web of Science databases and included studies in English published between 2012 and 2022 investigating the clinical outcomes of non-surgical PD management in humans. We have identified 20 distinct conservative treatment strategies. Among the oral therapeutics, only the use of phosphodiesterase type 5 inhibitors is currently recommended for clinical use in patients with concomitant erectile dysfunction. The use of collagenase from Clostridium histolyticum is supported by the best quality evidence in terms of intralesional injections for patients suffering from significant penile curvature; however, interferon alpha-2b can also be an option in such patients. Among other non-invasive methods, extracorporeal shockwaves can be useful for pain reduction, and penile traction therapy can lead to a reduction in penile curvature and plaque size. Despite a wide range of non-surgical methods available for PD treatment, the majority are not supported by sufficient scientific evidence, and the treatment efficacy is underwhelming. Further research on the subject of non-surgical management of PD is highly warranted.

Intralesional collagenase Clostridium histolyticum vs. verapamil injections in males with Peyronie's Disease: A prospective, matched-pair, non-blinded, randomised clinical study comparing clinical outcomes and patient satisfaction rates

PURPOSE

To compare clinical outcomes and patient satisfaction rates between intralesional verapamil (ILV) and collagenase Clostridium histolyticum (CCH) injections in males with Peyronie's disease (PD).

MATERIALS AND METHODS

Following ethics approval, PD patients were prospectively enrolled in this open-label non-blinded study. Patients were randomised to receive ILV or CCH injections with penile remodelling every fortnightly for 6 courses. Patient demographics, change in penile curvature, International Index of Erectile Function-15 and Peyronie's Disease Questionnaire (PDQ) scores as well as overall patient satisfaction and Patient Global Impression of Improvement (PGI-I) scores were recorded at pre-treatment and 6-, 12- and 24-month post-treatment.

RESULTS

A total of 50 males were recruited and divided into ILV (n=25) and CCH (n=25) groups. The mean changes in penile curvature were -16.8 (standard deviation [SD] 7.65) degrees in ILV and -28.2 (SD 11.5) degrees in CCH groups (p<0.01). Patients in the CCH group scored better than the ILV group on the PDQ psychosexual symptoms (-2.14 vs. -2.9; p<0.01) and symptom bother score (-3.88 vs. -4.16; p=0.08). Minor treatment-related adverse events were more common in the CCH group. The overall satisfaction rate on a 5-point scale was 4.1 in ILV and 4.5 in CCH groups, and there was no statistically significant difference in the PGI-I scores between the 2 groups (p=0.14).

CONCLUSIONS

CCH therapy is more effective than ILV to treat a carefully selected group of males with PD, with a reasonable safety profile and a higher high level of patient satisfaction rate in the short term.

Peyronie's disease - outcomes of collagenase clostridium histolyticum injection: A systematic review

Objective

To review recent literature pertaining to collagenase clostridium histolyticum (CCh)and other intralesional (IL) therapies for the treatment of Peyronie’s disease (PD). 

Methods

A systematic search of literature was performed using MEDLINE and PubMed.‘Peyronie’s Disease Clostridium Histolyticum’, ‘Peyronie’s Disease Intralesional’, ‘Peyronie’sDisease Causes’, and ‘Atypical Peyronie’s Disease’ were used as query entries. Inclusion criteriarequired English text from 1980 onwards and have a full text available. Records were reviewed for study power, accuracy, and relevance to our research topic. The review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria.

Results

Recent literature supports the notion that CCh is the most effective IL treatment forpatients with typical and atypical PD. The capstone CCh study was the IMPRESS trial thatshowed a 34% reduction in curvature with a mean (SD) – 17.0 (14.8)° reduction with IL CCh,while men in the placebo saw an average 18.2% decrease in penile bend with a mean (SD) – 9.3 (13.6)° per person (P < 0.001). A shortened protocol for IL CCh treatment offered a 31.4%reduction in curvature, while decreasing cost and office visits, potentially increasing patientcompliance. Lastly, literature shows CCh is used most in atypical cases, with ~64.8% of patients being treated with CCh, probably because of the high efficacy and safetyprofile that it offers. Serious complications associated with CCh include urethralinjury, corporal rupture, and penile fracture.

Conclusion

Since the approval of CCh by the United States Food and Drug Administration in2013, it has been a staple in the treatment of PD, and here we report the continuedsuperiority of this therapy. CCh is an effective, minimally invasive option in most PDpopulations; however, recent changes have made CCh unavailable for commercial use outside the United States, impacting many patients who have previously benefited.
