ABOUT DIABETIC RETINOPATHY
Diabetic retinopathy is an ocular complication of diabetes mellitus. While the pathogenesis is unclear, hallmark features include vaso-obliteration, ischemia, excessive VEGF production, and vascular permeability. These changes result in vision loss. While anti-VEGF injections are the standard of care, not all patients respond to treatment in a similar manner. Improved therapies are therefore needed.

About Diabetic Macular Edema
Diabetic macular edema is a leading cause of vision impairment among people within the working- age population. It is caused by fluid accumulation in the macula, or central portion of the eye, that causes the macula to swell. Of an estimated 285 million people with diabetes mellitus worldwide, approximately one third have signs of DR and of these, a further one third of DR is vision-threatening DR, including diabetic macular edema (DME).
About Humanized anti-Semaphorin 3A antibody
The Antibody specifically binds Semaphorin 3A and inhibit Semaphorin 3A-mediated cellular response. Semaphorin 3A is an axon elongation guidance factor which regulates normal neuronal pattern development. It was reported that Semaphorin 3A increase vascular permeation that causes leakage and develops diabetic macular edema. Chiome has successfully generated chicken IgM anti- Semaphorin antibodies by the original ADLib® System, and then humanized it for therapeutic drug development.

AmorChem spins out its SEMA 3A technology into SemaThera, with 1m$ seed investment
MONTREAL, Quebec – AmorChem is pleased to announce the creation of SemaThera, its second spin-off company focusing on a novel therapeutic approach to treat diabetic macular edema (DME) via the Semaphorin 3A (SEMA 3A) target. All rights to the SEMA 3A technology initially held by AmorChem have been transferred to SemaThera, with a first seed investment of 1M$CAD. This capital will allow SemaThera to select its lead candidate and start its early-stage development for the treatment of DME as a first indication.
The SEMA 3A technology has emerged from the laboratory of Dr Przemyslaw Sapieha, at the Hôpital Maisonneuve-Rosemont (HMR, CIUSSS de l’Est-de-l’Île-de-Montréal), who identified SEMA 3A as a novel target for ocular diseases. He discovered that SEMA 3A promotes vascular leakage and contributes to diabetesrelated macular edema. His work identified increased levels of SEMA 3A in the early stages of DME in a mouse model, while VEGF levels remained as low as levels observed in non-diabetic controls. Inhibiting SEMA 3A with a biological TRAP appears to be a relevant approach to preventing vascular leakage, inflammation, apoptosis and pathological cytoskeleton remodelling. “Diabetic macular edema is a common feature of retinopathies and affects a fourth of diabetic patients. It is the most prevalent ophthalmologic condition faced by diabetic patients and the leading cause of vision loss in adults of working age. Today, up to 40% of DME patients are poor-responders to anti-VEGF therapies and intravitreal injections of SEMA 3A inhibitor is clearly seen as a promising option” explains Dr Elizabeth Douville, Managing Partner at AmorChem.
“The spin off of SemaThera validates again the AmorChem model; identifying academic projects with high commercial potential, validating them within the academic setting and then spinning them off into companies” adds Dr. Inès Holzbaur, Managing Partner at AmorChem.
SEMATHERA’S MANAGEMENT TEAM
Upon creation of SemaThera, AmorChem appointed Maxime Ranger, Ph.D., MBA, as Chief Executive Officer, and Dr. Przemyslaw Sapieha as Chief Scientific Officer of the company. As a serial entrepreneur, Dr. Ranger will ensure the transition of company activities, which will first select the lead biological TRAP and then conduct preclinical studies in view of clinical Phase I. Moreover, the next financing round remains a priority to support IND-enabling GLP studies and Phase I safety program. As CSO of the company, Dr Sapieha remains a key driver to build value around the SEMA 3A technology. His deep expertise in cellular biology and retinopathies will allow him to lead the development towards next-generation SEMA 3A inhibitors.
WORLDWIDE, EXCLUSIVE LICENSE SIGNED BETWEEN SEMATHERA AND UNIVALOR
SemaThera signed an exclusive, worldwide, license with Univalor on a series of SEMA 3A TRAP inhibitors to be developed and used in various retinopathies and other non-ocular inflammatory diseases. «Univalor is pleased by the creation of SemaThera to pursue the development of this novel therapeutic approach.
