Rigicon Infla10® Three-Piece Inflatable Penile Prosthesis (ERASE ED)

Official title

Evaluation of the Rigicon Infla10® Three-Piece Inflatable Penile Prosthesis for the Treatment of Patients With Erectile Dysfunction

Overview

This study evaluates the long-term safety and efficacy of the use of the Rigicon Infla 10® Three-Piece Inflatable Penile Prosthesis in patients with erectile dysfunction. This study follows patients implanted with the Rigicon Infla 10® Three-Piece Inflatable Penile Prosthesis for up to 3 years after implantation. This study will take approximately 6 months to enroll all subjects. (14 days, 6 weeks, 6 months, 12 months,18 months, 24 months, and 36 months, post-procedure. ) Subjects will be followed per protocol and institutional standard of care for ED and comorbidities.

Detailed description

Erectile dysfunction (ED) is a common male sexual dysfunction associated with a reduced quality of life for patients and their partners. Incidence of ED increases with age and is associated with depression, obesity, diabetes mellitus, hypertension, cardiovascular disease and benign prostatic hyperplasia. ED is diagnosed with symptoms of (1) inability to attain or sustain a penile erection during sexual activity and (2) a reduction of penile rigidity in \>75% of sexual encounters during six months period. ED is estimated to affect approximately 52% of men in age of 40 to 70 years.It is projected in 2025, the worldwide ED prevalence of about 322 million. ED usually has organic causes, such as damage of arteries, smooth muscle and fibrous tissue. This resuls in impairment of blood flow to and from penis due to diabetes, renal disease, atherosclerosis and vascular disease.

Management of ED involves in life style modification, medical, surgical interventions, and possibly, in the future, tissue- engineering or cellular or gene therapy. Oral phosphodiesterase type 5 inhibitor (PDE5i), which works with sexual stimulation, is an effective medical therapy for ED with an excellent safety profile. Intracavernosal injection of or topical application vasoactive drug have also been studied. The first inflatable penile prosthesis was introduced in 1973 and current models of inflatable penile prostheses include the AMS 700 series, Coloplast Titan device and Zephyr ZSI device. A patient-activated inflatable penile prosthesis (IPP) provides patients a means to achieve dependable spontaneity for intercourse.

Rigicon has developed a three-piece inflatable penile prosthesis (IPP) (Infla10®) for the treatment of ED. This proposed study is to assess the safety and effectiveness of the Rigicon IPP in treating ED. Clinical literature and preclinical testing, including biocompatibility, device validation and verification, and animal studies support the safety and efficacy of this device for the intended therapy.

Interventions

• Device Rigicon Infla 10® Three-Piece Inflatable Penile Prosthesis
  Treatment: Erectile dysfunction

Primary outcome measures

• The primary safety outcome is the proportion of participants free from any device- or procedure-related adverse event of CTCAE Grade ≥2 through 12 months post-procedure, graded per CTCAE v5.0 and IPP-specific mapping. [Time frame: 12 months]
• The primary effectiveness endpoint is a binary "pass" or "fail" objective axial rigidity test, assessed at 12 months. [Time frame: 12 months]

Secondary outcome measures (3)

• Durability [Time frame: 12 months]
• International Index of Erectile Function - Erectile Function (IIEF-EF) Domain Score [Time frame: Baseline (pre-implantation) and Months 3, 6, 12, 18, 24, and 36 post-implantation.]
• Rosenberg Self-Esteem Scale (RSES) Total Score [Time frame: Baseline (pre-implantation) and Months 3, 6, 12, 18, 24, and 36 post-implantation.]

Eligibility criteria

Inclusion criteria

• Male ≥22 years of age.
• Diagnosed with erectile dysfunction (impotence).
• Agree to receive Infla10® three-piece IPP as an ED treatment.
• Willing to complete all protocol required follow-up visits and tests.

Exclusion criteria

• 1\. Contraindication to general anesthesia.
• Known allergy or sensitivity to product materials as indicated in the device labeling.

• Patients who are receiving immunosuppressive drugs or have a history of kidney transplantation
• Uncontrolled diabetes (Fasting Blood Sugar FBS) >300 or HbA1c ≥9.0 on morning of surgery)

• Active urogenital infection or active skin infection in region of surgery or systemic infection at the time of assessment.
• Clinically significant comorbidities or presence of unstable conditions (e.g. cardiovascular, lung, renal \[serum creatinine > 2.0 mg/dl\], hepatic, bleeding disorders, or metabolic impairment) that may confound the results of the study or in the judgment of the physician investigator preclude safe procedure.
• Any cognitive disorder that interferes with or precludes direct and accurate communication with the study investigator regarding the study or affects the ability to complete the study questionnaires.
• Lacking manual dexterity or mental abilities necessary to operate the device.
• Expected life expectancy < two years.
• Unwilling or unable to sign the Informed Consent.
• Unwilling or unable to comply with the follow-up study requirements.
• Currently participating in an investigational drug or another investigational device exemption (IDE) study.
• Incarcerated subjects
• Psychogenic erectile dysfunction
