Kinarus is currently developing KIN001 as an oral treatment for COVID-19 and has plans to develop KIN001 in wet age-related macular degeneration and idiopathic pulmonary fibrosis. The granted U.S and European patents also provide Method of Use Claims for the combination of pamapimod and pioglitazone in the treatment of cancer such as lung cancer, ovarian cancer, and cancer of the GI tract.

About KIN001

KIN001 is an orally administered combination of two drugs, pamapimod and pioglitazone. Pamapimod is a potent inhibitor of the p38 mitogen-activated protein kinase (MAPK), central for the cellular response in many diseases. Pioglitazone is an agonist of the peroxisome proliferator-activated receptor (PPAR) gamma, a marketed therapy for the treatment of type 2 diabetes. Kinarus has discovered that the drug combination increases the efficacy and durability of therapeutic response in preclinical models reflecting various diseases with substantial unmet medical need. KIN001 possesses anti-viral, anti-inflammatory, and anti-fibrotic activity, supporting its potential broad utility. KIN001 is currently under evaluation in a Phase 2 clinical trial in COVID-19. The “KINETIC” trial is a fully-powered, randomized Phase 2 trial in hospitalized COVID-19 patients.

Kinarus AG is a Swiss clinical-stage biopharmaceutical company focused on bringing differentiated treatments to patients suffering from viral, respiratory, and ophthalmic diseases. Kinarus’ differentiated therapeutic candidate, KIN001, has broad potential in numerous therapeutic areas.
