At ExoSurge®, We Have A Commitment to Science


Our clinician partners and patients rely on us to stand by our technology, and undergo thorough testing to the highest standards. This is why we describe our protocols, use controls whenever possible, showcase our complete results, and explain who conducts our trial.  This is the standard we feel all science should be held to, and at Soliton, we lead by example.

ExoSurge® Proof-of-Concept Trials (POC)

Our journey searching for an effective conservative treatment for Peyronie's disease spanned over twenty years ago. We explored and tested over 50 different approaches to plaque removal in that span.

It was in 2014 that we administered our first successful Proof-of-Concept (POC) Trial involving a study of seven patients with moderate to severe Peyronie's, each treated with an earlier version of the ExoSurge® IPG device.

In a single 20-minute treatment, the (IPG) device was applied under the shaft skin and directly to the surface of the patients’ plaques and fibrosis, following an interlesional injection of 1 ML of verapamil. The treatments required no anesthesia, caused no bruising, incurred minimal swelling or bleeding, and were evaluated as relatively painless by the trial participants. We performed 15 more IPG treatments to the affected areas, once weekly.

Follow-up assessments were performed at 3 months.

At the end of the 12-week POC Trial, 67% of patients reported noticing a change in the amount of palpable plaque and 31% observed a change in erect curvature (when applicable).

This early study served as the basis for our initial patent applications for the technology.

ExoSurge® 2021 Retrospective Study: Validation for Further Study

Between 2014 and 2021, we treated hundreds of Peyronie's patients at our urology clinic in Atlanta, Georgia. We sought to improve and refine our approach to treating Peyronie's Disease. We also developed breakthrough observations and the development of new working theory for the evaluation of Peyronie's cases that helped speed progress.

We were late maintaining comparative baseline and follow up duplex Doppler ultrasonography of our patient's fibrous tissue plaques as the basis for evaluating success with permanent removal of Peyronie's plaques with our treatment technology. Even within our 2021 Peyronie's Retrospective Study, a large percentage of patients (40%) were only about "half done" with therapeutics when we closed the study on October 31, 2020. The closing date for the retrospective study was driven by needs from our corporate finance operations at that time.

We feel results shared in our 2021 retrospective study provided strong evidence for the administration of prospective clinical trials for ExoSurge®.

ExoSurge® Upcoming and Future Studies and Trials

ExoSurge® 2024 Retrospective Study Expansion: Validation for Prospective Clinical Trials


We anticipate doubling the scale of our 2021 retrospective study comparing baseline and follow-up sonographic evidence of elimination of fibrous tissue plaques as well as changes in Peyronie's symptoms such as erect penile curvature.

Notably, we did not use PTT (penile traction therapy) with our first study group, so we are eager to observe the effect of PTT on the improvement of erect curvature associated with Peyronie's disease in this second group of patients.

We believe that these results demonstrate the need for prospective clinical trials.

ExoSurge® Active / Acute Phase Treatment Retrospective Study

During routine patient care at our Atlanta clinic, we observed that ExoSurge treatments appeared optimal for treating cases of Peyronie's disease in the active phase.

Specifically, the treatments prevented the formation of the characteristic post-acute penile injury fibrotic masses. In addition, patients reported that post-injury penile discomfort disappeared after only two or three ExoSurge treatments.

This study aims to refine protocols for treating patients in the active phase of Peyronie's disease and enhance outcomes.

ExoSurge® with other Non-Traditional Intralesional Injections Study

The majority of the shared insights from other non-traditional intralesional injection therapies used worldwide to treat Peyronie's disease have been observed and tested. However, we have not yet formalized this analysis to determine what role any may play in enhancing EXoSurge technology's performance.

This study will attempt to close this disparity.


ExoSurge® Xiaflex
® / CCH "Repairs" Case Studies

Patients who have previously "tried and failed" intralesional CCH injections have been seen in our clinic. ExoSurge® has allowed us to treat these patients and repair their Peyronie's disease.

We have also encountered patients whose CCH injections were previously successful, but whose Peyronie's symptoms returned, typically with unusually morphed erectile morphologies, such as a "S" curve. Additionally, we have been able to resolve these cases.

Treatment following intralesional CCH injections must be modified in comparison to untreated cases. In this study, we aim to identify these protocols for future clinical partners.

ExoSurge® Complementary
Surgical Intervention Study

EXO Chief Medical Officer Kenneth J. Carney, MD PHARM came up with an idea of combining a revised form of Peyronie's surgery with ExoSurge technology to radically speed up healing on select cases.

Which Peyronies cases are best suitable for this new CurveFree® treatment?
How do the results of CurveFree compare to those of traditional ExoSurge?
What are the potential ExoSurge® CurveFree side effects?

These are merely a few of the hypotheses we expect to test with this analysis.

ExoSurge® Calcified Plaque Accelerator Study

We've invented a new device that substantially accelerates the recovery of patients with large, densely calcified Peyronie's plaque.

We intend to produce a study detailing the success of this novel technology in treating select patients.

ExoSurge® Prospective Clinical Trials


ExoSurge® Prospective Clinical Trials

Without a doubt, the most exciting study on our horizon will be our the prospective clinical trials for ExoSurge® technology. This is essential for our vision of gaining FDA approval for our technology which is essential to achieve insurance reimbursement where this breakthrough can be used to heal all men suffering from Peyronie's.

By early 2025, we plan to have recruited and selected our clinical trials director, finalized protocols and parameters for comparative management within our study with an independent review board and recruited our first study partner clinics around the USA. We are planning for our prospective trails to be administered in double blind placebo format
