Outcome Measures
Primary Outcomes (2)
Number of Participants With Success at 36 Months
The primary endpoint of the study was to achieve non-inferiority of transvaginal repair with Xenform over NTR at 36 months as compared to baseline. Success was based on a composite of objective and subjective measures. 1. Subjective success was achieved if the patient denied symptoms of vaginal bulging per Pelvic Floor Distress Inventory (PFDI-20) question 3, answering "no" or "yes" but "Not at all" bothersome (\< 2). 2. Anatomic success (in the operated compartment): * Anterior segment: Leading edge of anterior prolapse was at or above the hymen or Pelvic Organ Prolapse Quantification System (POP-Q) point Ba ≤ 0. * Apical segment: The vaginal apex did not descend more than one-half into the vaginal canal (i.e., POP-Q point C \< -1/2 TVL) for multi-compartment prolapse or POP-Q point C ≤ 0 for single compartment apical prolapse. 3. No retreatment for POP: no additional surgical treatment for POP in the segment(s) of the vagina treated at the index surgery or no pessary use
36 Months
Number of Participants With One or More Serious Device-related and/or Procedure-Related Adverse Events
Co-primary endpoint of the study was to achieve non-inferiority of transvaginal mesh repair with Xenform to NTR for safety by comparing rates of serious device-related or serious procedure-related complications between baseline and the 36-month time point.

Eligibility Criteria
You may qualify if:
- Subject is female
- Subject is at least 18 years of age
- Subject has pelvic organ prolapse with the leading edge at or beyond the hymen. At or beyond the hymen is defined as POP-Q scores of Ba≥0 (for prolapse of the anterior compartment alone) or C≥0 (for prolapse of the apical compartment alone) or C≥-1/2 TVL and Ba≥0 (for a multi-compartment prolapse that includes the anterior and apical compartments).
- Subject reports a bothersome bulge they can see or feel per PFDI-20, question 3, response of 2 or higher (i.e., responses of "somewhat", "moderately", or "quite a bit")
- Subject or subject's legally authorized representative is willing to provide written informed consent
- Subject is willing and able to comply with the follow-up regimen
You may not qualify if:
- Subject is pregnant or intends to become pregnant during the study
- Subject has an active or chronic systemic infection including any gynecologic infection, untreated urinary tract infection (UTI) or tissue necrosis
- Subject has history of pelvic organ cancer (e.g. uterine, ovarian, bladder, colo-rectal or cervical)
- Subject has had prior or is currently undergoing radiation, laser therapy, or chemotherapy in the pelvic area
- Subject has taken systemic steroids (within the last month), or immunosuppressive or immunomodulatory treatment (within the last 3 months)
- Subject has systemic connective tissue disease (e.g. scleroderma, systemic lupus erythematosus (SLE), Marfan syndrome, Ehlers Danlos, collagenosis, polymyositis, polymyalgia rheumatica)
- Subject has chronic systemic pain that includes the pelvic area or chronic focal pain that involves the pelvis
- Subject has uncontrolled diabetes mellitus (DM)
- Subject has a known neurologic or medical condition affecting bladder function (e.g., multiple sclerosis, spinal cord injury or stroke with residual neurologic deficit)
- Subject is seeking obliterative vaginal surgery as treatment for pelvic organ prolapse (colpocleisis)
- Subject is not able to conform to the modified dorsal lithotomy position
- Subject is currently participating in or plans to participate in another device or drug study during this study
- Subject has a known sensitivity to any Xenform component
- Subject has had previous prolapse repair with mesh in the target compartment
- Subject is planning to undergo a concomitant prolapse repair with use of mesh in the non-target compartment
