Exclusion criteria

Exclusion criteria: • Previous FSH treatment not leading to conception. • Past or current use of finasteride within 3 months prior to screening. • Any history of anatomical disorder of the pituitary gland or testes. • Any structural abnormalities of the vas deferens (unilateral or bilateral) at screening. • Any known, clinically significant, systemic disease in addition to the trial indication that might negatively impact fertility. • Known history or presence of clinical varicocele (subclinical and Grade 1 varicocele are acceptable). • Known history of cryptorchidism, testicular torsion, or orchitis. • Known abnormal karyotype (including Y-chromosome microdeletion). • Current or past treatment of urogenital (kidney, bladder, testicular, or prostate) cancer as well as history of chemo- or radiotherapy that can have impact on testes. • Any known uncontrolled non-gonadal endocrinopathies (thyroid, adrenal, pituitary disorders). • Administration of hormonal preparations, agents known to impair testicular function or affect sex hormone secretion, and known or suspected teratogens within 3 months prior to screening.

Design outcomes

Primary

MeasureTime frame
Main Objective: - To investigate the effect of FE 999049 treatment of men with idiopathic infertility on the chance of spontaneous pregnancy in their female partners;Secondary Objective: - To investigate the effect of FE 999049 on semen parameters and endocrine profiles in men with idiopathic infertility - To evaluate the safety and immunogenicity of FE 999049 in men with idiopathic infertility;Primary end point(s): Spontaneous pregnancy observed in female partner within 9 months after randomisation of male subject, where spontaneous pregnancy is defined as vital pregnancy (documentation of at least one intrauterine gestational sac with fetal heartbeat by ultrasound);Timepoint(s) of evaluation of this end point: Within 9 months after randomisation

Secondary

MeasureTime frame
Secondary end point(s): - Positive ßhCG (positive urine ßhCG test) observed in female partner? - Time from randomisation to spontaneous pregnancy observed in female partner in calendar time and number of menstrual cycles - Changes in semen parameters (semen volume, sperm concentration, total count, motility, morphology, and DNA fragmentation) from prerandomisation to 3, 6, and 9 months after randomisation - Treatment responders defined by either spontaneous pregnancy observed in female partner, or increase of total sperm count or total motile sperm count to 50% over average baseline at 6 and/or 9 months - Changes in serum hormone concentrations (follicle-stimulating hormone [FSH], luteinising hormone [LH], inhibin B, testosterone, and estradiol) from randomisation to 3 and 6 months after randomisation - Changes in free testosterone concentration from randomisation to 3 and 6 months after randomisation - Treatment-induced anti-FSH antibodies, overall as well as with neutralising capacity - Immune-related adverse events;Timepoint(s) of evaluation of this end point: Timepoint as indicated in each applicable endpoint.
