Is this trial a fit for you?

Likely a good fit

Premenopausal Japanese women who wish to conceive, have congenital or acquired LH and FSH deficiency, an antral follicle count of ≥5 per ovary, and no more than one prior ART stimulation without pregnancy.

Probably not a fit

Women without LH/FSH deficiency, those with very low ovarian reserve (AFC <5), significant uterine abnormalities, or partners with sperm unsuitable for ART are unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 3 interventional trial enrolls premenopausal Japanese women with congenital or acquired LH and FSH deficiency who are planning assisted reproductive technology (ART). Participants receive controlled ovarian stimulation with either follitropin alfa/lutropin alfa (MBJ-0011) or hMG, with standard co-medications such as cetrorelix acetate, corio gonadotropin alfa, and progesterone gel used according to the protocol. Investigators will monitor ovarian response, pregnancy outcomes, and safety over about 5.5 months for nonpregnant participants or up to 13 months if pregnancy occurs. Key eligibility includes an antral follicle count of at least 5 per ovary, a partner semen analysis suitable for ART, and no clinically significant uterine abnormality.

Why it matters

Potential benefit: If successful, the combined follitropin alfa/lutropin alfa regimen could provide an effective, targeted stimulation option for women with LH/FSH deficiency undergoing ART.

How similar studies have gone: Recombinant combined FSH+LH therapies similar to follitropin alfa/lutropin alfa (for example, marketed FSH+LH combinations) have shown benefit in some patients with LH deficiency, so this approach builds on prior clinical experience.
