Interferon alpha-2b (Beijing Kawin Technology)

Peyronie's disease characterizes a condition in which there is angular curvature of the penis. We know that the most patients with Peyronie's disease will not have spontaneous resolution of their penile curvature. As such, patients who desire treatment can elect for either surgical or nonsurgical therapy. Herein, we discuss the contemporary nonsurgical management options for Peyronie's disease.

Nonsurgical management options for Peyronie's disease include oral therapy, intra-lesional injections, and penile traction therapy. At the time of this review, there is essentially no high-level evidence demonstrating any benefit for oral therapy. Penile traction therapy has evolved over the past decade with second-generation devices demonstrating strong efficacy and more convenient treatment regimens. Intra-lesional options include collagenase Clostridium histolyticum (CCH), verapamil, and interferon alpha-2b. The IMPRESS trial garnered the strongest level of evidence (two randomized, double-blind, placebo-controlled trials) to support the safety and efficacy of CCH. Verapamil is an option supported by several urological societies; however, the evidence supporting its efficacy is inconsistent between several notable series and randomized studies. IFN alpha 2b can produce modest improvement in curvature, however, is not available for use in North America.

Herein, we will discuss notable advances in nonsurgical management of Peyronie's disease.
