DNTH103 is an investigational long-acting classical complement pathway inhibitor designed as a less frequent and convenient subcutaneous injection with the potential to treat people living with severe autoimmune diseases. DNTH103, a fully human monoclonal antibody, is designed to selectively target only the active form of the C1s complement protein, inhibiting only the classical complement pathway, with the aim of treating patients with a lower dosing volume as a convenient subcutaneous injection suitable for a self-administered pre-filled pen. Inhibiting the active form of the complement target seeks to address a critical treatment gap in current complement therapies that do not bind selectively to the active protein, wasting a significant amount of the drug on inert proteins. DNTH103 selective inhibition of the classical pathway is engineered to preserve important immune activity of the lectin and alternative complement pathways needed to protect the body against infections from encapsulated bacteria. DNTH103 is also enhanced with YTE half-life extension technology to further reduce dosing frequency.
DNTH103 has a steady cadence of clinical milestones including top-line Phase 1 data aiming to confirm potent classical pathway inhibition and favorable, extended pharmacokinetics expected by the end of 2023, initiation of a Phase 2 trial in generalized Myasthenia Gravis expected in the first quarter of 2024 followed by two additional planned Phase 2 trial initiations in other neuro indications, and planned initiation of an open label proof of efficacy trial in Cold Agglutinin Disease with patient data anticipated in the second half of 2024.
About the Proposed Transaction, Management and Organization
Pre-merger Dianthus stockholders (including Dianthus stockholders issued shares of Dianthus common stock and pre-funded warrants in the concurrent private financing) are expected to own approximately 78.7% of the combined company and pre-merger Magenta stockholders are expected to own approximately 21.3% of the combined company. The percentage of the combined company that Magenta’s stockholders will own as of the close of the transaction is subject to adjustment based on the amount of Magenta’s net cash at the closing date.
