Nuvig Therapeutics Nabs $161M to Construct Case for a Higher Strategy to Autoimmune Illness
Customary remedy for a lot of autoimmune illnesses contains medication that suppress the immune system. Even when this strategy works (and it doesn’t work for everybody), power immunosuppression places sufferers prone to infections amongst different problems. Nuvig Therapeutics is creating a first-in-class drug that might supply another remedy for autoimmune illnesses and the startup now has $161 million to advance scientific improvement of its lead program.
Nuvig goals to deal with autoimmune illness by tapping right into a built-in mechanism of the physique that tamps down inflammatory pathways. The Menlo Park, California-based firm’s medication are proteins engineered to bind to sort II Fc receptors, a category of receptors that regulate immune responses. The corporate says the binding of its drug to those receptors results in the growth of regulatory T cells, or Tregs, a sort of immune cell that suppresses immune responses. This strategy additionally downregulates quite a few inflammatory pathways .
Lead Nuvig program NVG-2089 has Part 1 outcomes exhibiting it was protected and effectively tolerated. Additionally vital, the outcomes confirmed the drug engaged its goal. In Part 2, Nuvig will check NVG-2089 as a remedy for power inflammatory demyelinating polyneuropathy (CIDP), a uncommon dysfunction by which the immune system assaults myelin, the protecting sheath protecting nerve fibers. This illness results in nerve and motor issues in addition to progressively worsening muscle operate.
Customary CIDP remedy contains intravenous immunoglobulin (IVIg), an infusion of antibodies sourced from wholesome donors. This remedy supplies a affected person with antibodies that block the inflammatory processes that harm myelin. Immunosuppressants are one other CIDP remedy choice. Not all sufferers reply to those therapies, however there’s already a brand new different. This previous June, the FDA expanded the approval of Argenx drug Vyvgart Hytrulo to incorporate CIDP. This injectable drug, which was initially authorized to deal with generalized myasthenia gravis, is an antibody fragment designed to bind to and block the neonatal Fc receptor (FcRn). Consequently, disease-driving autoantibodies go to a mobile system that degrades proteins.
By way of the primary three quarters of 2024, Argenx reported greater than $1.4 billion in product gross sales, a 77.5% enhance over the identical interval in 2023. These figures contains Vyvgart, the unique intravenously infused formulation of the FcRn inhibitor. Argenx has touted its drug’s potential makes use of in a variety of autoimmune indications and the corporate is in varied phases of scientific improvement testing its FcRn-blocker in a number of illnesses. Equally, Nuvig says its drug has the potential to deal with many autoimmune indications. However first, the corporate will see how its drug works in CIDP.
Nuvig selected CIDP as a result of it is a sign the place IVIg is the usual of care and there’s nonetheless unmet want for a better-tolerated remedy that’s not immunosuppressive, co-founder and Chief Scientific Officer Pamela Conley stated in an e mail. She added that her firm’s strategy is distinct from that of the Argenx drug and different FcRn inhibitors. Most autoimmune illnesses, together with CIDP, should not solely mediated by the presence of autoantibodies, she defined. Slightly, many of the harm in CIDP is mediated by immune cells that infiltrate the myelin that shield nerve cells.
An FcRn blocker like Argenx’s drug does nothing to scale back the infiltration of immune cells into myelin, Conley stated. Moreover, blocking FcRn results in an as much as 80% discount in general circulating antibodies. Persistent upkeep of those low antibody ranges is immunosuppressive, placing sufferers prone to an infection.
Slightly than being immunosuppressive, Nuvig’s drug is immunomodulatory, Conley stated. The drug gives a broader strategy by down regulating the response of immune cells that drive irritation whereas additionally increasing and activating Tregs, which is analogous to what occurs with IVIg. Conley added that scientific assessments of the Argenx drug confirmed the general response of CIDP sufferers was lower than what has been noticed in CIDP research with IVIg.
“We consider that the [mechanism of action] of NVG-2089 will result in higher efficacy in CIDP than what was noticed with Vyvgart,” Conley stated.
Nuvig, which relies on analysis from The Rockefeller College, emerged from stealth in 2022 backed by a $47 million Sequence A spherical. The brand new Sequence B spherical was co-led by Sanofi Ventures, Blue Owl Healthcare Alternatives (previously Cowen Healthcare Investments), and Norwest Enterprise Companions.
