The company's lead product candidate is pegcetacoplan that is in Phase III clinical trials for the treatment of geographic atrophy (GA) in age-related macular degeneration and paroxysmal nocturnal hemoglobinuria (PNH) diseases.

In addition, the company develops APL-2006, a bispecific C3 and VEGF inhibitor for treating complement-mediated disorders; APL-1030, a C3 inhibitor for the treatment of multiple neurodegenerative diseases; and the combination of EMPAVELI and a small interfering RNA, or siRNA for reducing the production of C3 proteins by the liver. It has a collaboration and license agreement with Swedish Orphan Biovitrum AB (publ) to co-develop pegcetacoplan; and a research collaboration with Beam Therapeutics Inc. focused on the use of Beam's base editing technology to discover new treatments for complement-driven diseases.
