Aphton's granted European Patent 0741744 for Immunogens Against Gonadotropin Releasing Hormone has completed the opposition period in the European Patent Office without any opposition filed.
The European patent 0741744 covers Aphton's proprietary immunogens for neutralizing the key reproductive hormone gonadotropin releasing hormone, called GnRH.
Since this first pilot study in humans, Aphton's clinical trials program is directed, in part, to increase the percentage of patients exhibiting strong antibody responses (and therapeutic benefit), to achieve levels exhibited previously in patients with other Aphton immunogens.
