AXN-027

Boston biotech Axonis Therapeutics has raised a $115 million Series A to test whether its oral drug AXN-027 can help patients with focal epilepsy and diabetic neuropathic pain. The financing, disclosed Wednesday morning, will get the biotech into the clinic around the end of this year, or about the same time Ovid Therapeutics expects to begin human trials with a similar approach by way of an AstraZeneca platform it licensed. Both companies are looking at KCC2, a CNS chloride transporter that is key to electrical signaling in the brain. KCC2 allows for neuronal GABA signaling. The GABA pathway has been targeted by multiple drugmakers , including Sage’s postpartum depression medicine Zurzuvae , but biotechs have yet to enter the clinic with a focus on KCC2, CEO Joanna Stanicka told Endpoints News . “Often GABA treatments can induce global inhibition, which leads to this cognitive impairment and sedation often reported by patients,” Stanicka said, adding that focused inhibition should avoid those side effects. The 13-employee biotech also said Wednesday that it added Donald Manning as chief medical officer and Jeff Imbaro as operating chief. Manning previously held the same post at Travecta, Pacira BioSciences and Adynxx. Imbaro was in the same role at stroke-focused Elevian, and before that he was a founding member of Vertex-acquired Semma Therapeutics. Axonis was founded by spinal cord injury patient advocate and board observer Bob Yant about 15 years ago, but it didn’t become “operational” until 2019, Stanicka said. Prior to the Series A, Axonis had raised about $34 million in seed funding and about $9 million in government and foundation money, Stanicka said. Its investors include Cormorant Asset Management, venBio, Sofinnova Investments, Merck’s corporate venture arm and others. The startup anticipates the Series A will fund AXN-027 through Phase 2 proof-of-concept studies, she said.
