MYK-461 (also known as Mavacamten) is a small-molecule modulator of cardiac myosin that targets the underlying sarcomere hypercontractility of hypertrophic cardiomyopathy, one of the most prevalent heritable cardiovascular disorders. Studies on isolated cells and muscle fibers, as well as intact animals, have shown that MYK-461 inhibits sarcomere force production, thereby reducing cardiac contractility. In Phase II clinical trials MYK-461 reduces left ventricular outflow tract obstruction and improve exercise capacity and symptoms in patients with obstructive hypertrophic cardiomyopathy. Phase III clinical trials are currently ongoing.

ABL-001 (asciminib), a potent and selective allosteric tyrosine-protein kinase ABL1 inhibitor that is undergoing clinical development testing in patients with Chronic myeloid leukemia (CML) and Philadelphia Chromosome-positive Acute Lymphoblastic Leukemia. is a tyrosine-protein kinase ABL1 inhibitor. In contrast to catalytic-site ABL1 kinase inhibitors, ABL001 binds to the myristoyl pocket of ABL1 and induces the formation of an inactive kinase conformation. ABL001 and second-generation catalytic inhibitors have similar cellular potencies but distinct patterns of resistance mutations, with genetic barcoding studies revealing pre-existing clonal populations with no shared resistance between ABL001 and the catalytic inhibitor nilotinib. ABL001 was tested on mice with a particularly aggressive type of CML. The combination of ABL001 and nilotinib led to complete disease control and eradicated CML xenograft tumors without recurrence after the cessation of treatment. ABL001 is being tested in clinical trials for treatment of CML and Philadelphia Chromosome-positive Acute Lymphoblastic Leukemia alone and in combination with niotinib, imatinib or dasatinib.

Ponesimod is an experimental drug for the treatment of multiple sclerosis (MS) graft-versus-host disease and psoriasis. It acts on certain types of white blood cells (lymphocytes) which are involved in the autoimmune attack on myelin seen in multiple sclerosis (MS). Ponesimod is an orally active, reversible, and selective sphingosine-1-phosphate receptor (S1PR1) modulator. The drug is in phase II clinical trial for the treatment of graft-versus-host disease. In addition, the phase III clinical trial comparing ponesimod to teriflunomide in relapsing-remitting MS is ongoing.

Tepotinib is an investigational small molecule inhibitor of the c-Met receptor tyrosine kinase. Alterations of the c-Met signaling pathway are found in various cancer types and correlate with aggressive tumor behavior and poor clinical prognosis. Tepotinib is a potent and selective c-Met inhibitor, >200-fold selective for c-Met than IRAK4, TrkA, Axl, IRAK1, and Mer. Tepotinib is currently in Phase I/II trials in liver cancer and lung cancer.
