Lutropin alfa
EMD Serono's Luveris — the only recombinant human LH ever FDA-approved (2004, accelerated approval). Discontinued from the US market in 2012; approval formally withdrawn in 2016 after EMD Serono notified the FDA it could not complete the required postmarketing pregnancy-outcome trial.
A recombinant human luteinizing hormone produced in CHO cells with amino acid sequence identical to pituitary LH, approved under FDA accelerated-approval regulations in October 2004 as Luveris (EMD Serono) for stimulation of follicular development in infertile hypogonadotropic-hypogonadal women with profound LH deficiency (LH <1.2 IU/L) when used concomitantly with Gonal-f. In April 2012, EMD Serono informed the FDA it was not feasible to complete the post-marketing trial required to verify clinical benefit on time-to-pregnancy; the product was withdrawn from the US market that May, and the NDA was formally withdrawn by the FDA in April 2016. Not available in the United States as of April 2026; the molecule remains available in some other markets.
Mechanism of action
LH/CG receptor (LHCGR) agonism on ovarian theca cells, supporting androgen production that serves as substrate for granulosa-cell aromatization to estradiol during follicle maturation. In LH-deficient hypogonadotropic-hypogonadal women, LH supplementation is required alongside FSH for adequate follicular development and estradiol response.
Primary uses
- Historical: stimulation of follicular development with concomitant rFSH in hypogonadotropic-hypogonadal women with LH deficiency (US indication, 2004–2012, approval withdrawn 2016)
Typical dosing
Historical dose: 75 IU SC daily concomitantly with 75–150 IU Gonal-f SC daily (two separate injections) until follicular development, not to exceed 14 days unless imminent follicular development was evident.
Regulatory status
FDA-approved under accelerated-approval regulations (21 CFR part 314, subpart H) on October 8, 2004, as Luveris (lutropin alfa for injection, EMD Serono/Merck Serono) for stimulation of follicular development — in combination with Gonal-f — in infertile hypogonadotropic-hypogonadal women with profound LH deficiency (LH <1.2 IU/L). US market discontinuation May 2012. EMD Serono requested withdrawal of the NDA under 21 CFR 314.150(d) because the required postmarketing study could not be completed; the FDA formally withdrew approval in April 2016. The clinical benefit of Luveris was never confirmed in a completed postmarketing trial. Remains marketed in some ex-US jurisdictions.
