American Medical Systems Announces 1,000th Patient Enrolled in PROPPER Registry

February 19, 2015

Largest Prospective, Multi-Year, Penile Prosthetic Registry Advances Understanding of Real-World Satisfaction with Penile Prostheses For Erectile Dysfunction Patients

MINNEAPOLIS, Feb. 19, 2015 /PRNewswire/ -- American Medical Systems Inc. (AMS), a subsidiary of Endo International plc (NASDAQ: ENDP) (TSX: ENL) and leading provider of medical technologies for pelvic health, today announced the enrollment of the 1,000th patient in the largest prospective, multi-year, global registry study of penile prosthetic outcomes in the world.

The study, entitled PROPPER (Prospective Registry of Outcomes with Penile Prosthesis for Erectile Restoration), is sponsored by AMS and is being conducted by a team of experienced urologists at 11 North American sites.  It aims to better characterize real-world patient satisfaction and other outcomes among men who are receiving prosthetic implants to treat their erectile dysfunction (ED).  All patients enrolled in the registry will be implanted with penile implants manufactured by AMS, the majority of whom will receive the three piece inflatable penile prosthesis (IPP), the AMS 700.

Using data from the registry, ten abstracts have been presented at several medical meetings since 2013. Additionally, a peer reviewed study titled Reservoir Alternate Surgical Implantation Technique: Preliminary Outcomes of Initial PROPPER Study of Low Profile or Spherical Reservoir Implantation in Submuscular Location or Traditional Prevesical Space authored by Edward Karpman, et al, was published in the Journal of Urology in January 2015. The study illustrates how reservoir placement has evolved to support greater utilization of three piece devices as well as confidence in treating men post robotic radical prostatectomy. "PROPPER is the first-of-its kind observational registry that captures critical data about real-life outcomes to aid patients and their doctors in making important decisions about their ED treatment options," said Karpman. "This is an ongoing process, and we expect the database to continue to grow as more men, with the support of their partners, consider penile implants."

"We are pleased to be able to partner with an outstanding group of physician investigators in order to add to the understanding of the safety and performance of our devices as they are utilized in clinical practice.  We anticipate that the large number of men enrolled in this study will yield robust results that, once published, will be informative for implanting physicians, referring physicians and for patients," said Dr. Ronald Morton, Chief Surgical Officer, AMS.

Previous clinical research showed that of ED patients who received a penile implant, 93 percent were satisfied with their device1. Furthermore, in a study of both patients and partners, 92 percent of patients and 96 percent of their partners reported excellent or satisfactory sexual activity2.

"American Medical Systems, an established world-leader in treatments for ED and other pelvic health disorders, is committed to advancing the treatment of ED, to give men and their partners effective, world-class treatment options," said Dev Kurdikar, Senior Vice President and General Manager, Men's Health, AMS. "We're very pleased to reach this milestone in the PROPPER registry - the largest prospective study of its kind.  Such investments are aligned with our strategic intent of being able to provide physicians, patients and other healthcare system stakeholders with impactful data."

About PROPPER Registry

The registry ( Identifier NCT01383018) uses questionnaires as well as direct physician to patient physical examination and history taking, enabling the investigating physicians to prospectively measure patient responses at regular intervals over a one-to five-year period. Several key metrics are being analyzed, including device effectiveness, durability, complications and patient satisfaction; quality of life will also be analyzed, as defined though several validated patient questionnaires.

About Erectile Dysfunction

About 1 in 5 American men over the age of 20 experience some degree of ED3, adding up to an estimated 30 million men4. For many patients, drugs and other therapies are not a satisfying option with treatment discontinuation rates of up to 60%. Penile implants, first invented and developed at AMS, have helped more than 300,000 men return to an active and satisfying sex life5 over the past 40 years6.

About the AMS 700 Series Penile Prosthesis Product Line

The AMS 700™ Series Penile Prosthesis product line is intended for use in the treatment of chronic, organic, male erectile dysfunction (impotence). These devices are contraindicated in patients who have active urogenital infections or active skin infections in the region of surgery or (for the AMS 700™ Penile Prosthesis with InhibiZone™ Antibiotic Surface Treatment) have a known sensitivity or allergy to rifampin, minocycline, or other tetracyclines. Implantation will make latent natural or spontaneous erections, as well as other interventional treatment options, impossible. Men with diabetes, spinal cord injuries or open sores may have an increased risk of infection.
