Product Description

Onametostat (JNJ-64619178) Onametostat (JNJ-64619178) is a PRMT5 inhibitor with high selectivity and potency (subnanomolar range, PRMT5-MEP-50 IC50=0.14 nM) under different in vitro and cellular conditions, paired with favorable pharmacokinetics and safety properties.

Targets

PRMT5 0.14 nM

In vitro

JNJ-64619178 binds into the SAM binding pocket and reaches the substrate binding pocket to inhibit PRMT5/MEP50 function in a time-dependent manner. Broad cell line panel profiling of JNJ-64619178 reveals a wide range of sensitivity, which is indicative of a genomic dependency instead of a general cytotoxic on-target consequence of PRMT5 inhibition.

In vivo

JNJ-64619178, dosed orally (10 mg/kg, every day), shows selective and efficient blockage of the methylation of SMD1/3 proteins, which are crucial components of the spliceosome and substrates of PRMT5/MEP50. JNJ-64619178 also demonstrates tumor regression in a biomarker-driven human small cell lung cancer xenograft model (NCI-H1048) and prolongs tumor growth inhibition after dosing cessation. In rodent and nonrodent toxicology studies, a tolerated dose of JNJ-64619178 has been identified, with the observed toxicity consistent with on-target activity. In summary, JNJ-64619178 has a favorable preclinical package that supports clinical testing in patients diagnosed with lung cancer and hematologic malignancies1.
