Ipsen: Clinical Update For Decapeptyl 6-Month Formulation in Advanced Prostate Cancer
Ipsen (Paris:IPN) announced that its partner Debiopharm presented today the results of a phase III study with its new 6-month formulation of Decapeptyl(R)(1), a luteinizing hormone releasing hormone agonist (LHRHa) for the treatment of advanced prostate cancer. The results presented show similar efficacy and safety to the already marketed 1- and 3-month formulations of triptorelin.
This multicenter, open, non-comparative, phase III study on the efficacy and safety of two consecutive injections at a six-month interval of triptorelin 6-month formulation in 120 patients with advanced prostate cancer, showed that 97.5% of patients achieved castrate levels of serum testosterone 28 days after the first injection and that 93% of the patients maintained serum testosterone levels below castrate level (defined as < 1.735 nmol/L or 50 ng/dL) from week 8 to 48. These efficacy and safety results are similar to those obtained previously with repeated administrations of the 1- and 3-month formulations of triptorelin in previous studies. Furthermore, local tolerance is good with only 6.7% of the patients treated reporting spontaneously site injection adverse events.
On 31 October 2007, Ipsen exclusively in-licensed from Debiopharm know-how and new patent applications for the commercialization rights of Decapeptyl(R) (triptorelin pamoate) in the world excluding North America, and some other countries (Sweden, Israel, Iran and Japan).
Decapeptyl(R) is a peptide formulation for injection that was initially developed by Debiopharm and continues to be used mainly in the treatment of advanced metastatic prostate cancer. Additional indications developed subsequently include the treatment of uterine fibroids (a benign tumour of muscle tissues in the uterus), endometriosis (proliferation of endometrial tissue, the mucous membrane that lines the uterine wall outside the reproductive tract) prior to surgery or when surgery is not deemed appropriate, as well as early onset puberty and female infertility (in vitro fertilisation). Decapeptyl(R) is available in monthly or quarterly sustained-release formulations, as well as a daily formulation. The active substance in Decapeptyl(R) is triptorelin, a decapeptide analogue of GnRH (Gonadotrophin Releasing Hormone), a hormone secreted by the hypothalamus, which initially stimulates the release of pituitary gonadotrophins (hormones produced by the pituitary gland), which in turn control hormonal secretions by the testes and ovaries. Decapeptyl(R) was initially launched in France during 1986. At 31 December 2007, Decapeptyl(R) had marketing authorizations in over 60 countries, including 25 in Europe. In 2007, 59.7% of Decapeptyl(R) sales were generated in the five major European Countries, and reached a total of 235.1MEUR .
Debiopharm, which holds the patent to pamoate formulations of Decapeptyl(R) has granted Ipsen an exclusive licence to Decapeptyl(R) within the European Union (outside Sweden) and in certain other countries. Debiopharm has also granted Ipsen a co-exclusive licence to manufacture Decapeptyl(R) within the European Union (outside Sweden) and in certain other countries (with Debiopharm nonetheless retaining the right to manufacture and supply Decapeptyl(R) for its own purposes and those of its other licensees in territories not licensed to the Group).
