Develops GRI-0621 for idiopathic pulmonary fibrosis and GRI-0803 for autoimmune disease by regulating distinct NKT-cell populations. The pre-revenue company retains worldwide rights and expects successful development to support commercialization, licensing, or collaboration economics.
Develops GRI-0621, an oral candidate that inhibits iNKT-cell activity, for idiopathic pulmonary fibrosis, and GRI-0803, an oral activator of dNKT cells, for autoimmune disease, initially systemic lupus erythematosus and lupus nephritis. The former has completed an early clinical trial; the latter remains in IND-enabling development. The company retains worldwide rights and expects future commercialization, licensing, or collaboration economics if its programs succeed.
Operates from La Jolla with a focused internal team while relying on consultants, contract research organizations, contract manufacturers, investigators, and suppliers. Its near-term effort is concentrated on GRI-0621, whose further development requires FDA clearance and substantial capital or a strategic partner; it has no approved product, commercial infrastructure, or significant operating revenue.
