Brief Summary:
This is a prospective, observational study in women using Gonal-F filled-by-mass (FbM) in ovarian hyperstimulation as part of their in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment at infertility clinics in Korea. The purpose of this study is to assess Gonal-F FbM in a practical setting encompassing all subject groups and local practices.

Condition or disease Intervention/treatment
Multifollicular Stimulation Drug: Gonal-F (Follitropin alfa)

Detailed Description:

Follicle stimulating hormone (FSH) is a complex hetero-dimeric glycoprotein used therapeutically to stimulate follicular development in the ovary. The technical advance of recombinant technology to manufacture FSH has resulted in a biochemically pure FSH preparation with high batch-to-batch consistency. The protein content can be reliably quantified in mass units by size exclusion high performance liquid chromatography. These developments have enabled recombinant human FSH follitropin alfa (Gonal-F) to be filled and released in vials on the basis of mass with a variability of only ±2%. In one study, the FbM batches appeared to deliver a more consistent therapeutic effect than the filled-by-bioassay batches. In another randomized trial, self-administration and subjects' satisfaction were significantly higher in the pen device group than the conventional syringe group. Local reactions at injection sites and pain were significantly higher in the conventional syringe group than in the pen device group. The authors concluded that the pen device of Gonal-F is safe, convenient, and less painful, with more subject satisfaction than the conventional syringe form.

This prospective, multicentric, observational study is planned in women using Gonal-F FbM in ovarian hyperstimulation as part of their IVF/ICSI treatment at infertility clinics in Korea. Subjects fulfilling the eligibility criteria shall be enrolled in a consecutive manner over a 9-month period (approximately 1500 subjects).


Primary objective:

  • To assess the effectiveness Gonal-F FbM

Secondary objectives:

  • To assess the safety and subject convenience of Gonal-F FbM in a normal clinical practice over a period of 9 months

Observational Model: Case-Only
Time Perspective: Prospective
Official Title: A Prospective, Multi-center, Observational Study of Gonal-F Filled by Mass Pens in Multifollicular Stimulation Prior to IVF/ICSI
Study Start Date : April 2009
Actual Primary Completion Date : March 2010
Actual Study Completion Date : March 2010

Intervention Details:
  • Drug: Gonal-F (Follitropin alfa)
    Follitropin alfa FbM solution for injection in a prefilled pen is available in three strengths: 300 IU/0.5 ml (22 µg/0.5 ml), 450 IU/0.75 ml (33 µg/0.75 ml) and 900 IU/1.5 ml (66 µg/1.5 ml). The starting dose is usually recommended to be between 150 and 300 IU. The dose is then adjusted according to the ovarian response.
    Other Name: Gonal-F

Primary Outcome Measures :
  1. Efficacy [ Time Frame: Start of treatment to confirmation of pregnancy ]
    Number of oocytes retrieved and clinical pregnancy rate per cycle

Secondary Outcome Measures :
  1. Efficacy, Safety and Convenience [ Time Frame: Start of treatment to confirmation of pregnancy ]

    Secondary efficacy parameters includes total Gonal-f dose; stimulation profile of IVF cycle; number of follicles > 14 mm on day of hCG; number of available embryos; pregnancy status (hCG test, ultrasound exam); on the day of embryo transfer (ET).

    Convenience and safety parameters includes subject convenience rated by completing a questionnaire, local tolerance assessment (local reactions at the injection site, pain, satisfaction and convenience)
