Mild Versus Conventional Ovarian Stimulation for Poor Responders Undergoing In Vitro Fertilisation

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
Siristatidis Charalampos, MD, PhD, National and Kapodistrian University of Athens
ClinicalTrials.gov Identifier:
NCT01319708
First received: March 8, 2011
Last updated: November 7, 2015
Last verified: November 2015
  Purpose
The investigators will examine the balance between IVF success in terms of outcome parameters, using a mild ovarian stimulation protocol, opposing it to the conventional stimulation regimens in poor responders undergoing IVF.

Condition Intervention Phase
Infertility Procedure: mild ovarian stimulation Procedure: conventional ovarian stimulation Phase 1 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: Mild Versus Conventional Ovarian Stimulation for Poor Responders Undergoing In Vitro Fertilisation

Further study details as provided by Siristatidis Charalampos, MD, PhD, National and Kapodistrian University of Athens:

Primary Outcome Measures:
  • number of oocytes (COCs) [ Time Frame: at oocyte recovery ]

Secondary Outcome Measures:
  • Number/rate of participants whom the IVF cycle was cancelled [ Time Frame: After the 1st week of ovarian stimulation, no oocytes at OR ]
  • clinical pregnancy rate [ Time Frame: 6 weeks ]
    Presence of fetal heart at transvaginal ultrasound at 6 weeks of gestation or 6 weeks after starting the intervention

  • live birth [ Time Frame: more than 20 weeks ]
  • miscarriage [ Time Frame: pregnancy loss before 20 weeks of gestation, after a positive pregnancy test ]
  • stimulation characteristics [ Time Frame: from start of stimulation until embryo transfer ]
    total dose of gonadotropins administered,

  • cancellation rate [ Time Frame: from start of stimulation until ET ]
    when premature ovulation was evident by the loss of follicle(s) prior to oocyte recovery, and in cases where there were no oocytes retrieved or no embryos produced for transfer and in failed fertilization


Enrollment: 50
Study Start Date: March 2011
Study Completion Date: September 2015
Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: mild ovarian stimulation
100 mg CC by day 2 till 6, plus antagonist plus gonadotrophin 150-200IO until HCG triggering
Procedure: mild ovarian stimulation
100-150 mg of clomiphene citrate from day 2 till day 6 of the cycle and 150 mg of gonadotrophins as soon as 1 follicle is more than 14mm together with 1 fixed dose of GnRH antagonist until egg recovery
Active Comparator: conventional ovarian stimulation
300-450 IU of FSH starting by day 2 of menstrual cycle together with a fixed dose of GnRH antagonist starting by day 6 till egg recovery, or same doses using a GnRH agonist long protocol
Procedure: conventional ovarian stimulation
300-450 IU of FSH starting by day 2 of menstrual cycle together with a fixed dose of GnRH antagonist starting by day 6 till egg recovery, or same doses with GnRH agonist long protocol
