We are also very humbled to have the opportunity to achieve another milestone in our industry, as Collategene®, if approved, will be Turkey’s first approved gene therapy”

* Named Patient Program

Named patient programs (NPP) provide controlled, pre-approval access to drugs in response to requests by physicians on behalf of specific, or “named”, patients before those medicines are licensed in the patient’s home country. Through these programs, patients are able to access drugs in late-stage clinical trials or approved in other countries for a genuine, unmet medical need, before those drugs have been licensed in the patient’s home country.

About Collategene® (Beperminogene Perplasmid)

HGF (Hepatocyte Growth Factor) was discovered in 1984 in Japan as a protein to accelerate the growth of hepatocytes. Although research on HGF initially focused on the development of medicines for liver diseases, in 1995 the research team, led by Dr. Ryuichi Morishita at Osaka University, found that HGF has a novel function as an angiogenic growth factor that promotes the growth of blood vessels. The local delivery of HGF Plasmid (Plasmid encoding HGF DNA) developed a new method of regenerating blood vessels and has strong potential to become a curative medicine for ischemic patients who are suffering from deteriorating circulation due to clogged blood vessels.

Examples of diseases caused by the clogging of blood vessels include: critical limb ischemia (most advanced stage of peripheral artery disease, consisting of arteriosclerosis obliterans and Buerger's disease), which may ultimately lead to the amputation of a lower limb due to necrosis caused by poor circulation.

In March 2019, AnGes,Inc. obtained conditional and time-limited approval for HGF Plasmid gene therapy indicated for improvement of ulcers in patients with chronic arterial occlusive disease (arteriosclerosis obliterans and Buerger’s disease) who have inadequate response to standard drug therapy and who are not eligible for revascularization, and it is the first gene therapy medicine approved in Japan. Commercialization of Collategene® started in September 2019 in Japan.
