Registration Number
NCT01794208
Lead Sponsor
Glycotope GmbH
Brief Summary

The aim of the current study was the determination of the recommended standard treatment dose of FSH-GEX(TM) in women undergoing intracytoplasmic sperm injection (ICSI) treatment as assessed by follicle growth.

Detailed Description

This was a phase II, randomized, assessor-blind, comparator-controlled, multiple dose study in women undergoing ICSI treatment.

The primary objective of the study was the determination of the recommended standard treatment dose of FSH-GEX™ as assessed by follicle growth dynamics in women between 18 and 37 years of age who were undergoing intracytoplasmic sperm injection treatment.

Primary Outcome Measures
NameTimeMethod
Number of folliclesday of hCG injection; variable timeframe; up to 18 days for maximum

The number of follicles with a diameter of ≥ 12 mm on the day of human chorionic gonadotropin (hCG) injection after stimulation with follicle stimulating hormone (FSH)

Secondary Outcome Measures
NameTimeMethod
Cumulus-oocyte-complexesat oocyte retrieval; 32 - 36 hours after hCG injection

Number of retrieved cumulus-oocyte-complexes

Oocytes retrievedat oocyte retrieval; 32 - 36 hours after hCG injection

Number of oocytes retrieved (metaphase II)

Follicular responseevery second day up to hCG injection; variable timeframe; up to 18 days for maximum

For each ovary the number of follicles were classified and summarised as follows: mean diameter 8.0 - 9.9 mm, 10.0 - 11.9 mm, 12.0 - 13.9 mm, 14.0 - 15.9 mm, 16.0 - 17.9 mm, 18.0 - 19.9 mm, and \>19.9 mm as determined by transvaginal ultrasonography

Two pronuclei oocytesone day after oocyte retrieval

Number of two pronuclei (2PN) oocytes one day after follicle puncture

Biochemical pregnancy rate14 to 20 days after oocyte retrieval

Based on positive β-hCG pregnancy test

Clinical pregnancy rateapprox. 4 to 6 weeks after last FSH dose

Based on clinical or ultrasound parameters (gestational sac, foetal heart beat

Implantation rateapprox. 4 to 6 weeks after last FSH dose

Number of foetal sacs on sonography divided by number of embryos transferred per embryo transfer

Estradiol and inhibin B serum levelsevery second day up to hCG injection; variable timeframe; up to 18 days maximum

Concentration of Estradiol and Inhibin B in Serum after FSH stimulation

Adverse events, ovarian hyperstimulation syndrome, anti-drug-antibodies, overall tolerabilityup to 4 to 6 weeks after last FSH dose

Incidence of adverse events, ovarian hyperstimulation syndrome, anti-drug-antibodies, overall tolerability

Number of doses and total dose of FSHvariable timeframe; up to 18 days for maximum

The total dose is the amount of FSH-GEX(TM) or Gonal-f® administered to each patient during the stimulation period
