Results from a comparison of CCH alone vs CCH and traction with RestoreX demonstrated a mean 33.8 degree (49%) curvature improvement with combined therapy compared to 19-20 degrees (30-31%) with CCH alone or CCH and other traction devices). These results currently represent the greatest improvements with CCH in published literature and further build upon phase IIb results which demonstrated that mechanical traction (via manual modeling in the phase IIb trial) represents a critical factor in achieving improvements with CCH.\n\nThe investigators' team additionally published a survey of men who had experienced suspected penile fractures with CCH and demonstrated greater curvature improvements without any loss / worsening of erectile function. This critical study highlighted that conservative management of suspected fractures should not only be considered a standard of care in managing suspected fractures, but also that these men achieved better final outcomes (again highlighting the importance of the combination of mechanical curvature correction in addition to CCH management).\n\nBased on the above findings, the investigators' team began performing a more aggressive manual modeling protocol. This novel protocol included several notable innovations: dilution of the 0.9 mg of CCH in 0.7 ml of diluent, injection to the erect penis to assure accurate injection, repeat curvature assessments with each series (due to changing of the point of maximal curvature), incorporation of RestoreX traction therapy post injection, and 'aggressive' manual modeling (equivalent of 10-15 lbs of force) to achieve curvature correction. Preliminary (unpublished - abstract submitted to SMSNA 2021) results from these men demonstrated a median \\~60% curvature improvement. Importantly, several of the patients had previously undergone 8 CCH injections with outside providers and were able to similarly achieve a median 60% improvement with the investigators' injection / modeling protocol.\n\nThese preliminary findings have several important ramifications for the treatment of PD:\n\n1. Men who have previously not achieved adequate curvature correction with 4 series of CCH injections may benefit from additional injections using a more aggressive traction protocol.\n2. A more aggressive traction protocol would benefit patients to achieve greater outcomes than with previously reported protocols.\n\n1.2 Investigational Treatments\n\nThe current study would randomize men 1:3 into one of two treatment cohorts: 1. Observation followed by CCH or 2. CCH followed by observation. This study design offers the benefits of a randomized, controlled trial (highest level of evidence). RCTs are particularly important in PD, where the disease changes over time in a percentage of men as a function of its natural history. This would also allow blinding of measurements using photographs (single-blinded assessments), which provides further study rigor.\n\n1. No treatment (control) followed by CCH. Men in this cohort would undergo baseline assessments followed by no treatment for 6 months and then repeat assessments. Men would then cross-over to CCH treatment and undergo up to 8 injections (or until curvature is \\<15 degrees). Interval assessments would be performed with the 1st injection of each series, and final assessments would then be performed 6 weeks following the final injection.\n2. CCH followed by no treatment. Men in this cohort would undergo baseline assessments followed by up to 8 injections of CCH (or until curvature is \\<15 degrees).
