About this study

Official title: Prospective, Multicenter, 60 Months, Single Arm Cohort Study to Evaluate the Efficacy and Safety of the Ultra-Light-Weight Mesh CAlistar S in Transvaginal Pelvic Organ Prolapse Repair

Prospective long-term evaluation of the performance and safety of Calistar S for transvaginal pelvic organ prolapse repair in women with anterior POP with or without apical vaginal involvement

Read the detailed description

Calistar S Single Incision Pelvic Organ Prolapse (POP) Repair System is intended for transvaginal reestablishment and reinforcement of the physiologic anatomy of the female pelvic floor in non-fertile women with anterior pelvic organ prolapse with or without apical vaginal wall involvement in both, recurrent pelvic organ prolapse and primary pelvic organ prolapse when other surgical procedures are expected to fail (i.e. complex primary prolapse).

The treatment kit consists of the lightweight mesh, two single-use introducers and 3 tissue anchoring system (TAS) anchors for fixation to the sacrospinous ligament. The product is approved in accordance with the CE Directive 93/42/EEC.

The utilization of synthetic implants in POP repair became increasingly popular in the last decade. The cumulative success rate of synthetic implants in anterior compartment repair is as high as up to 93%.However, meshes have been recently scrutinized due to high adverse event reporting after unreflected utilization of meshes which raised concerns of patients safety; furthermore taking into account the complexity of adverse event mesh management. This led to a vanishing of various meshes in transvaginal POP repair. Nevertheless, the further development of light weight meshes, the experience of the surgeon and the assessment and patients selection are well known factors reducing the rate of adverse events significantly.

Therefore, in the current trial the efficacy and safety of calistar S in a highly selected patient population will be evaluated.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients with Cure of pelvic organ prolapse

    Number of patients accomplishing the composite endpoint after 24 months including anatomic, subjective and retreatment components

    Measured: 24 months

Secondary outcomes (14)
  1. Change of prolapse specific quality of life according the validated Questionnaire Prolapse quality of life questionnaire in comparison between baseline and follow-up

    Differences between Baseline and Follow-Up result of the questionnaire of each patient regarding Quality of life and the correlating domains will be evaluated. P-QoL, Score: 0-100, the higher the score, the higher the impact of prolapse symptoms and the lower quality of life.

Where is the study taking place?

The record lists 6 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Patients with Cure of pelvic organ prolapse (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03821142, which also lists 16 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
