IsomAb is one step closer to bringing its peripheral artery disease (PAD) treatment to the clinic after closing a £7.5-million ($9.4 million) seed financing led by Broadview Ventures. Existing investor SCVC also participated in the round, as did MEIF Proof of Concept & Early Stage Fund, which is managed by Mercia Ventures and part of the Midlands Engine Investment Fund.
The company’s lead candidate, ISM-001, is a preclinical isoform-specific monoclonal antibody (mAb) in development to treat PAD in patients with concomitant metabolic syndrome and type 2 diabetes.
ISM-001 is designed to enhance the body’s natural workaround when a buildup of fats block blood vessels, limiting blood flow to tissues and causing heart attack or stroke.
The production of new blood vessels to bypass the clogged ones relies on a balance of two VEGF-A isoforms: VEGF-A165a and VEGF-A165b. If levels of the latter are too high, the body is unable to create new vessels.
ISM-001 inhibits VEGF-A165b to rebalance the two isoforms and promote blood vessel production.
"IsomAb offers a fresh approach to the treatment of vascular disease. Although the initial focus will be on treating diabetics, research shows high levels of VEGF-A165b are also linked to increased risk of heart attack and stroke in non-diabetics, so it could have much wider applications,” Mercia Ventures partner Hannah Tapsell Chapman said.
Tuesday’s round will fund IsomAb through a clinical trial authorisation submission to UK regulators.
