Comparing follitropin alfa/lutropin alfa versus hMG for Japanese women with LH and FSH deficiency undergoing assisted reproductive treatment.

A Parallel-group Treatment, 2-arm Study to Compare the Efficacy and Safety of Follitropin Alfa and Lutropin Alfa Fixed Dose Combination Versus hMG for Inducing Follicular Development in Japanese Participants With LH and FSH Deficiency Undergoing ART

Phase 3 Interventional Merck Healthcare KGaA, Darmstadt, Germany, an affiliate of Merck KGaA, Darmstadt, Germany · NCT07340827

This will test whether a combined follitropin alfa/lutropin alfa injection works as well as hMG for Japanese premenopausal women with LH and FSH deficiency who are undergoing assisted reproductive technology.

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.

Who should consider this trial

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.

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.

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 performed: 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.
