Arrowhead Pharmaceuticals Inc. (NASDAQ: ARWR) today announced that its collaborator, Janssen Pharmaceuticals, Inc., (Janssen) one of the Janssen Pharmaceutical Companies of Johnson & Johnson, has disclosed its collaboration with Arrowhead on investigational compound JNJ-75220795, which is in a Phase 1 clinical study.

JNJ-75220795 is an investigational siRNA therapeutic developed using Arrowhead’s proprietary TRIM^TM platform and designed to reduce expression in the liver of patatin like phospholipase domain containing 3 (PNPLA3) as a potential treatment for patients with non-alcoholic steatohepatitis (NASH). PNPLA3 has strong genetic and preclinical validation as a driver of fat accumulation and damage in the livers of patients who carry the common I148M mutation.

Arrowhead entered into a research collaboration and option agreement with Janssen in October 2018, which resulted in collaboration on JNJ-75220795.

About Arrowhead Pharmaceuticals

Arrowhead Pharmaceuticals develops medicines that treat intractable diseases by silencing the genes that cause them. Using a broad portfolio of RNA chemistries and efficient modes of delivery, Arrowhead therapies trigger the RNA interference mechanism to induce rapid, deep, and durable knockdown of target genes. RNA interference, or RNAi, is a mechanism present in living cells that inhibits the expression of a specific gene, thereby affecting the production of a specific protein. Arrowhead’s RNAi-based therapeutics leverage this natural pathway of gene silencing.
