Abstract

Introduction
Collagenase clostridium histolyticum (CCH, Xiaflex®; Endo Pharmaceuticals) is the only FDA-approved non-surgical therapy for Peyronie’s Disease (PD). CCH is an effective alternative to surgery for patients with PD who have a palpable plaque and a curvature deformity of ≥30°. Clinicians who administer CCH must complete risk mitigation training, and access to specialists varies by region across the US. Identifying areas with low provider availability may improve patient access to this and other treatments for PD.

Objective
To review the availability of clinicians offering CCH for the treatment of Peyronie’s Disease in the conterminous United States.

Methods
We utilized a publicly available search tool on a website provided by Endo Pharmaceuticals to identify certified providers offering CCH in the conterminous United States. We created a list of 23 zip codes that, when surrounded by a 500-mile radius, encompass the entire conterminous United States. We then utilized the search tool to identify providers within those radii. The data gathered included the provider’s name, specialty, and practice address. Duplicate addresses were removed, but a single provider offering CCH at 2 different locations was considered 2 different data points. We compared the data relative to the American Urological Association’s “The State of the Urology Workforce and Practice in the United States” and 2021 State Population Estimates from the US Census Bureau.

Results
In total, 1948 locations offering CCH were identified (Figure 1a). The mean number of locations offering CCH per 100,000 state residents was 0.61 [SD 0.27] (Figure 1b). Wyoming had the highest number of locations per 100k residents with 1.39. New Mexico had the lowest with 0.05. The 10 states with the highest ratio of clinicians/locations (from high-low) per capita were Wyoming, Georgia, Rhode Island, Nebraska, Maryland, New Jersey, Kansas, North Carolina, South Carolina, and Alabama. The 10 states with the lowest were New Mexico, Delaware, Maine, Mississippi, Minnesota, Vermont, Missouri, Indiana, New Hampshire, and Idaho. The mean proportion of urologists providing CCH to total urologists (Figure 1c) was 0.15 [SD 0.07]. Wyoming had the highest proportion of 0.40 and New Mexico had the lowest of 0.02. The 10 states with the highest proportion (from high-low) were Wyoming, Georgia, Utah, Nebraska, Kansas, Alabama, Nevada, Arizona, South Carolina, and Oklahoma. The 10 states with the lowest proportion (from low-high) were New Mexico, Delaware, Maine, Vermont, New Hampshire, Minnesota, Missouri, South Dakota, and Mississippi.

Conclusions
There are notable differences in the relative availability of CCH providers across the US. These discrepancies may impact access to care, supporting an opportunity to expand training efforts. States with low numbers of treatment locations offering CCH per 100k residents relative to other states also had a low total proportion of urologists offering CCH as a treatment. There is room for current practicing urologists in these states and others to expand their practice to offer CCH and improve patient access to this important non-surgical treatment option.
