About this study

A retrospective observational anonymized cohort study of follitropin alpha biosimilar (Primapur®) as a pre-filled pen injector with a dose adjustment of 5 IU, aimed to investigate its efficacy and safety in a nonselected population with indications to assisted reproductive technologies (ART) was carried out. The ovarian stimulation (OS) protocols included:

monotherapy protocols with using only Primapur®; mixed protocols (recombinant and urinary-derived gonadotropins); short protocols with using antagonists of gonadotropin-releasing hormone (GnRH) and long protocols with GnRH agonists. The stimulation protocols were analyzed with Primapur® application for at least 5 days.

Treatment and study plan

Follitropin alfa

Drug

Subcutaneous injection of follitropin alpha biosimilar only, with daily dose 100-300 IU for 10 days, maximum of 15 days, using antagonists of GnRH or agonist of GnRH.

Other names: Primapur, Biosimilar

Follicle Stimulating Hormone/Luteinizing Hormone

Drug

Subcutaneous injection of follitropin alpha biosimilar, with daily dose 100-300 IU for at least 5 days, than added another gonadotropin for a maximum of 10 days, using antagonists of GnRH or agonist of GnRH.

Other names: Follitropin beta, Follitropin alfa + Lutropin alfa, Corifollitropin alfa, Menotropins, Follitropin alfa, Follitropin alfa biosimilar

Primary outcomes

  1. Number of Oocytes Retrieved

    Time frame: From date of start of ovarian stimulation with follitropin alpha up to 15 days

    The total number of retrieved oocytes at the day of ovum pick-up. No more than 37 hours from the introduction of the ovulation inducer (HCG or GnRH-agonist).

    Due to lack of efficacy of the therapy (ovarian stimulation was not completed and oocytes were not retrieved) the analysed population was: (1) Mixed protocols: recombinant and urinary-derived gonadotropins and antagonists/agonists of GnRH - 2625 participants (lack of efficacy: 78 participants, the analysed population was 2547 participants); (2) Monoprotocols: follitropin alpha biosimilar only and antagonists/agonists of GnRH - 2859 participants (lack of efficacy: 89, the analysed population was 2770); (3) Monoprotocols: follitropin alpha biosimilar only and antagonists of GnRH - 2183 participants (lack of efficacy: 59, the analysed population was 2124) and (4) Monoprotocols: follitropin alpha biosimilar only and agonist of GnRH - 676 participants (lack of efficacy: 30, the analysed population was 646).

  2. Percentage of Participants With Ongoing Clinical Pregnancy Per Embryo Transfer

    Time frame: At least 6 weeks after embryo transfer

    Ongoing clinical pregnancy per embryo transfer (detection of gestational sac and heartbeat from 6 weeks after transfer), n (ongoing pregnancy rate per transfer with known outcome, %).

    Due to delayed embryo transfers, the analysed population for "Ongoing clinical pregnancy per embryo transfer" was: (1) Mixed protocols: recombinant and urinary-derived gonadotropins and antagonists/agonists of GnRH - 2007 embryo transfers (1542 with known outcome); (2) Monoprotocols: follitropin alpha biosimilar only and antagonists/agonists of GnRH - 2213 embryo transfers (1800 with known outcome); (3) Monoprotocols: follitropin alpha biosimilar only and antagonists of GnRH - 1809 embryo transfers (1466 with known outcome) and (4) Monoprotocols: follitropin alpha biosimilar only and agonist of GnRH - 404 embryo transfers (334 with known outcome).

Secondary outcomes

  1. Number of Mature Oocytes

    Time frame: From date of start of ovarian stimulation with follitropin alpha up to 15 days

    Mature oocytes (MII stage of development).

    Due to lack of efficacy of the therapy (ovarian stimulation was not completed and oocytes were not retrieved) the analysed population was: (1) Mixed protocols: recombinant and urinary-derived gonadotropins and antagonists/agonists of GnRH - 2625 participants (lack of efficacy: 78 participants, the analysed population was 2547 participants); (2) Monoprotocols: follitropin alpha biosimilar only and antagonists/agonists of GnRH - 2859 participants (lack of efficacy: 89, the analysed population was 2770); (3) Monoprotocols: follitropin alpha biosimilar only and antagonists of GnRH - 2183 participants (lack of efficacy: 59, the analysed population was 2124) and (4) Monoprotocols: follitropin alpha biosimilar only and agonist of GnRH - 676 participants (lack of efficacy: 30, the analysed population was 646).

  2. Number of Fertilized Oocytes

    Time frame: From date of start of ovarian stimulation with follitropin alpha up to 16 days

    Fertilization rate (FR) is percentage of transformation of oocytes into two pronuclei (presence of two pronuclei: zygotes with 2PN).

    Due to lack of efficacy of the therapy (ovarian stimulation was not completed and oocytes were not retrieved) the analysed population was: (1) Mixed protocols: recombinant and urinary-derived gonadotropins and antagonists/agonists of GnRH - 2625 participants (lack of efficacy: 78 participants, the analysed population was 2547 participants); (2) Monoprotocols: follitropin alpha biosimilar only and antagonists/agonists of GnRH - 2859 participants (lack of efficacy: 89, the analysed population was 2770); (3) Monoprotocols: follitropin alpha biosimilar only and antagonists of GnRH - 2183 participants (lack of efficacy: 59, the analysed population was 2124) and (4) Monoprotocols: follitropin alpha biosimilar only and agonist of GnRH - 676 participants (lack of efficacy: 30, the analysed population was 646).

  3. Total Dose of Follitropin Alpha Biosimilar Protocol, IU

    Time frame: From date of start of ovarian stimulation with follitropin alpha up to 16 days

    Mean dose of follitropin alpha biosimilar for ovarian stimulation.

    Due to lack of efficacy of the therapy (ovarian stimulation was not completed and oocytes were not retrieved) the analysed population was: (1) Mixed protocols: recombinant and urinary-derived gonadotropins and antagonists/agonists of GnRH - 2625 participants (lack of efficacy: 78 participants, the analysed population was 2547 participants); (2) Monoprotocols: follitropin alpha biosimilar only and antagonists/agonists of GnRH - 2859 participants (lack of efficacy: 89, the analysed population was 2770); (3) Monoprotocols: follitropin alpha biosimilar only and antagonists of GnRH - 2183 participants (lack of efficacy: 59, the analysed population was 2124) and (4) Monoprotocols: follitropin alpha biosimilar only and agonist of GnRH - 676 participants (lack of efficacy: 30, the analysed population was 646).
