Vor Bio, a most cancers cell remedy developer that laid off almost all of its staff in a wind down of operations final month, has reemerged with new administration, an in-licensed lead drug candidate, and $175 million in financing to assist its new give attention to autoimmune illnesses.
Cambridge, Massachusetts-based Vor stated Thursday it has an settlement for unique rights to telitacicept, a drug that RemeGen has already teered to regulatory approvals in China for generalized myasthenia gravis (gMG), systemic lupus erythematosus, and rheumatoid arthritis. China-based RemeGen retains rights to the drug in its dwelling nation. This drug is presently in a world Section 3 examine in gMG that might assist an FDA submission.
In gMG, autoantibodies assault proteins necessary for the communication between nerves and muscle mass. The uncommon dysfunction results in issues corresponding to problem swallowing and muscle weak point. Development of gMG is mediated by a kind of immune cell referred to as a B cell. Vor’s new drug is a fusion protein designed to selectively inhibit B cell activating issue, or BAFF (often known as BlyS) and APRIL, two signaling proteins key to B cell survival.
Vor is just not the one firm going after one or each of these targets, however its give attention to gMG may assist it stand aside. Novartis’s zigakibart, a monoclonal antibody that blocks APRIL, is in Section 3 testing for immunoglobulin A nephropathy (IgAN). Vera Therapeutics blocks BAFF and APRIL with a fusion protein referred to as atacicept. In early June, Vera introduced this drug met its Section 3 objectives in IgAN; an FDA submission is deliberate for the fourth quarter of this yr. Vertex Prescription drugs goes after BAFF and APRIL with povetacicept, a fusion protein that was the centerpiece of its $4.9 billion acquisition of Alpine Immune Sciences final yr. Povetacicept has reached Section 3 testing in IgAN and a Section 2/3 scientific trial in major membranous nephropathy.
Remedy of gMG has welcomed new therapies lately, however none but that deal with BAFF and APRIL. The therapies obtainable embody medicine that block complement proteins related to the dysfunction (AstraZeneca’s Ultomiris and UCB’s Zilbrysq) and FcRn inhibitors (Argenx’s Vyvgart and Vyvgart Hytrulo; UCB’s Rystiggo). The latest FcRn inhibitor for gMG is Johnson & Johnson’s Imaavy, which landed its FDA approval in Could. Vor stated the Section 3 examine for telitacicept is enrolling sufferers within the U.S., Europe, and South America; preliminary outcomes are anticipated within the first half of 2027.
Vor Biopharma, co-founded by oncologist Siddhartha Mukherjee and startup creator PureTech Well being, was creating stem cell-derived cell therapies for blood cancers that might provide alternate options to presently obtainable CAR T-therapies for most cancers which might be made by harvesting and engineering a affected person’s personal T cells. The biotech went public in 2021, elevating almost $177 million. Regardless of making progress with clinical-stage packages, Vor was working low on money. In Could, the corporate ceased its scientific and manufacturing operations and laid off about 95% of its workers as explored strategic alternate options for the enterprise.
Vor’s CEO, Robert Ang, resigned Thursday, the corporate stated. The board of administrators has appointed Jean-Paul Kress to function the brand new chief govt. Kress is the previous CEO of MorphoSys, which was acquired by Novartis final yr. He’s additionally the previous chief govt of Syntimmune, which was acquired by Alexion Prescription drugs (now AstraZeneca’s uncommon illnesses subsidiary).
“Concentrating on BAFF/APRIL signaling with telitacicept represents a big development in addressing autoantibody pushed illnesses, which is very differentiated from different modalities on this house,” Kress stated in a ready assertion. “With a clinically superior asset, we’re uniquely positioned to develop this progressive remedy, with the purpose of creating a significant affect for sufferers residing with autoimmune illnesses around the globe.”
In its second quarter 2025 monetary report, Vor reported its money place was about $60 million. The corporate has shored up its funds with a $175 million personal placement introduced Thursday.
