Senior Medical Science Liaison (Neurology); West Region

About Us

We are developing potentially best-in-class therapies for patients living with severe autoimmune diseases. Our lead antibody, claseprubart (DNTH103), is purposefully engineered with extended half-life, improved potency, and high selectivity for only the active C1s complement protein that drives disease pathology – enabling less frequent and more convenient self-administered subcutaneous injections.

Our second clinical candidate, DNTH212 is a first and potentially best in class, bifunctional inhibitor that targets clinically validated and complementary disease modifying mechanisms, Type 1 IFN suppression and B cell modulation – enabling potential for improved clinical outcomes and patient friendly convenient, self-administered subcutaneous injections. Our newest candidate, DNTH312, is an internally developed, investigational, first-in-class, next-generation bifunctional fusion protein combining claseprubart and TACI to target

potent inhibition of aC1s and BAFF/APRIL. DNTH312 aims to be Phase 1 ready by year end 2027. To learn more, please visit www.dianthustx.com and follow us on LinkedIn.
