2002 JUL 18 - (NewsRx.com & NewsRx.net) -- According to a study published in the June issue of Fertility and Sterility, Bravelle (urofollitropin for injection, purified), a highly purified human-derived follicle-stimulating hormone (hFSH), administered subcutaneously (SC) and intramuscularly (IM), is comparable in activity and tolerability to recombinant follitropin beta (Follistim SC) for in vitro fertilization (IVF).
Bravelle was approved by the U.S. Food and Drug Administration (FDA) on May 6, 2002, for ovulation induction (OI) following pituitary suppression, a common step in the treatment of infertility. These and other data supporting the use of Bravelle in IVF are currently under review by the FDA.
"This study demonstrates that in IVF, premium-priced recombinant FSH showed no advantage in activity or tolerability over Bravelle, a highly purified preparation of human-derived FSH," said Wayne Anderson, president of Ferring Pharmaceuticals. "Bravelle is ideally suited to meet the needs of infertility specialists and their patients by providing an affordable treatment that combines human-derived hormone efficacy with recombinant hormone-like purity."
Bravelle SC, Bravelle IM, and Follistim SC were compared in a randomized, open-label, parallel group, multicenter trial in 177 patients, ages 18 to 39, undergoing controlled ovarian hyperstimulation for IVF. Patients who were successfully down-regulated (achieved pituitary suppression) were randomized into three groups and received Bravelle SC (n=60), Bravelle IM (n=59) or Follistim (n=58) once daily (225 IU to a maximum of 450 IU) for up to 12 days. Subsequently, human chorionic gonadotropin (hCG) was ...
