What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Triptorelin Acetate 3.75mg intramuscular injectionDrug

    Also called Diphereline 3.75mg intramuscular injection

    Triptorelin Acetate is a Gonadotrophin Releasing Hormone agonist (GnRHa).

    Triptorelin acetate for injection 3.75mg administered as described in the patient information sheet approved in China: one intramuscular injection of the product repeated every 4 weeks.

What is being measured

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

  1. Changes in the intensity of specific endometriosis symptoms from baseline pre-surgery

    The specific endometriosis symptoms include pelvic pain, dysmenorrhoea, pain at time of ovulation, dyspareunia to be assessed with a 10-cm visual analogue scale (VAS).

    Other symptoms (Amenorrhea, menorrhagia, metrorrhagia, Global GI symptoms \& urinary discomfort,) will be assessed by oral enquiry to the patients based on numerical scale from 0 to 10 (0 being the best and 10 the worst status).

    Measured: Every 3 months in the first 12 months after surgery and every 6 months in the following 12 months

Secondary outcomes (5)
  1. Recurrence rate of specific endometriosis symptoms

    Recurrence rate of specific endometriosis symptoms in the group of patients with mild or null symptoms score following surgery and Diphereline treatment.

    Measured: At 12 months and 24 months

  2. Change during the study period in symptom(s) having the highest intensity at baseline

    The highest intensity at baseline is defined as the symptom with the highest score on pre-surgery assessment.

    Measured: 24 months

  3. Rate of pregnancy in subjects

    Measured: At 12 months and 24 months

  4. Abdominal pain-free interval

    Assessed using a visual analogue scale (VAS).

    Measured: Every 3 months in the first 12 months after surgery and every 6 months in the following 12 months

  5. Disease profile of DIE patients treated by Diphereline and by duration of treatment.

    The disease profile (size of the lesion, locations etc…) will be detailed in each group of treatment duration by descriptive statistics.

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Deep Infiltrating Endometriosis (DIE), run by Ipsen at 18 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in China. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Changes in the intensity of specific endometriosis symptoms from baseline pre-surgery (time frame: Every 3 months in the first 12 months after surgery and every 6 months in the following 12 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 NCT01942369, which also lists 2 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.

How often is this information updated?
