approach & pipeline
DEFINED TARGETS.
BOUNDLESS IMPACT.
Dianthus Therapeutics is harnessing the power of selectivity to advance next-generation complement therapies to treat severe autoimmune diseases.
OUR INNOVATION
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.
Addressing both the disease and treatment burdens that disrupt the lives of patients.
OUR FOCUS
Claseprubart is an investigational, long-acting monoclonal antibody engineered to potently and selectively inhibit the active form of C1s, a clinically validated target in the classical complement pathway.
As the classical pathway plays a significant role in disease pathology across a range of neuromuscular disorders, claseprubart holds the potential to be a pipeline in a product – beginning with generalized Myasthenia Gravis (gMG), Multifocal Motor Neuropathy and Chronic Inflammatory Demyelinating Polyneuropathy.
Engineered with YTE half-life extension technology, claseprubart is intended to be the first subcutaneous complement therapy that can be self-administered as infrequently as once every two weeks for patients with severe, classical pathway-driven autoimmune disorders.
So patients can live healthier lives to their fullest potential.
BUILDING A NEUROMUSCULAR FRANCHISE WITH CLASEPRUBART (DNTH103)
Positive top-line Phase 1 data for claseprubart from 60 healthy volunteers across eight single and multiple-ascending dose cohorts validate claseprubart’s potent classical pathway inhibition with an approximate 60-day extended half-life and a potentially differentiated safety profile. Dianthus is building a neuromuscular franchise with ongoing trials of claseprubart in generalized Myasthenia Gravis, Multifocal Motor Neuropathy, and Chronic Inflammatory Demyelinating Polyneuropathy.
PIPELINE
Claseprubart – subcutaneous active C1s antibody
More than 100,000 people in the United States live with gMG, a chronic autoimmune disorder that causes progressive muscle weakness. Approximately 85% of people with gMG have AChR autoantibody-driven disease, driven by classical complement pathway activation.
Approximately 5,000 to 10,000 people in the United States live with MMN, a disease in which the immune system attacks peripheral nerve axons and myelin sheaths and classical complement pathway activation can facilitate progressive nerve damage. Up to 80% of patients are not adequately managed by current standard of care and there are no approved targeted biologic therapies for MMN.
More than 40,000 people in the United States live with CIDP, a neuromuscular condition driven by classical pathway activation that follows a relapsing-remitting or a progressive clinical course with the potential to result in substantial disability, loss of motor and sensory function. There are no approved targeted complement therapies for CIDP.
