Luveris(R) (lutropin alfa for injection) administered with follitropin alfa for injection, is proposed for the indication of stimulation of follicular development in infertile hypogonadotropic hypogonadal (HH) women with profound luteinizing hormone deficiency (LH < 1.2 IU/L). HH is a rare endocrine deficiency affecting between 2,800 and 5,600 women in the US and can range from mild to severe. The FDA had previously recommended that Serono study an endpoint of ovulation rates, an endpoint frequently used for products in ovulation induction. However, the Committee agreed that in this rare patient population the endpoint of follicular development was appropriate. "We are very pleased with the recommendation of the Advisory Committee supporting the efficacy of Luveris(R) for follicular development in this rare patient population and will continue to work closely with the FDA as it finalizes its review of this important new treatment," said Paul Lammers, MD, Chief Medical Officer, Serono, Inc. "Serono's development of Luveris(R) is part of our ongoing commitment to reproductive health and our leadership role in this area. Luveris(R) is the third of three recombinant fertility hormones developed exclusively by Serono." Luveris(R) is a recombinant form of luteinizing hormone (LH), a naturally occurring fertility hormone. It is the first and only drug product to contain LH exclusively that can address the unmet medical need for fertility treatment by profoundly LH deficient women. Women whose opportunities for pregnancy are limited by profound LH deficiency have no available treatment approved specifically for their condition. These women lack the ability to produce the hormones needed for full development of follicles in the ovaries, ovulation, and growth of the lining of the uterus sufficient to support implantation of a fertilized egg and early pregnancy. The Advisory Committee's recommendation was based on a review of the clinical development program conducted in patients with this rare condition, including a phase III confirmatory, double-blind, placebo-controlled, randomized trial. In this trial, patients were treated with either Luveris(R) or placebo, co-administered with Serono's recombinant follicle stimulating hormone (r-hFSH), Gonal-f(R) (follitropin alfa for injection). In the Luveris(R) and Gonal-f(R) treatment group, 17 patients (65.4%) achieved the primary endpoint of follicular development compared to two patients (15.4%) in the placebo and Gonal-f(R) group. The four-fold difference between the two groups was both clinically meaningful and statistically significant (p=0.006). In these studies, Luveris(R) was well tolerated with reported adverse events similar to those of other currently approved recombinant gonadotropin products. The Advisory Committee recommendation is considered by the FDA in making its decision regarding Luveris(R), which is expected before the end of this year. Luveris(R) received an Orphan Drug Designation from the FDA and is currently approved for the treatment of women with profound LH deficiency in 46 countries worldwide, including countries of the European Union such as France, Germany and the United Kingdom.
