A prespecified interim analysis revealed that Astrazeneca plc’s oral factor D inhibitor danicopan met the primary endpoint of a phase III trial as an add-on therapy for patients with paroxysmal nocturnal hemoglobinuria (PNH) who were also taking a C5 inhibitor, but who still experienced extravascular hemolysis.
The phase III miss disclosed Aug. 11 by Kubota Pharmaceutical Holdings Co. Ltd. subsidiary Kubota Vision Inc. in Stargardt disease put more eyes on the rare, inherited, juvenile-onset form of macular degeneration, for which nothing is approved.
LONDON – The EMA recommended approval of Apellis Pharmaceuticals Inc.’s C3 complement inhibitor, Aspaveli (pegcetacoplan), to treat paroxysmal nocturnal hemoglobinuria, but has diverged from the FDA, excluding treatment-naïve patients adding its use should be restricted to those who have failed to respond to C5 inhibitor drugs.
Apellis Pharmaceuticals Inc.’s win with one phase III trial and narrow miss with an identical one testing pegcetacoplan in geographic atrophy secondary to age-related macular degeneration caused Wall Street to punish the company while rewarding competitor Iveric Bio Inc.
Now that Apellis Pharmaceuticals Inc.’s Empaveli pegcetacoplan has won FDA approval as the first targeted C3 therapy for treating paroxysmal nocturnal hemoglobinuria (PNH), the cost of treating the rare blood disorder is hefty.
Apellis Pharmaceuticals Inc. could receive up to $1.25 billion from Swedish Orphan Biovitrum (Sobi) AB in their collaboration to develop systemic pegcetacoplan, a C3 therapy for treating several rare diseases in hematology, nephrology and neurology.
Apellis Pharmaceuticals Inc.’s CEO, Cedric Francois, said his firm’s phase III study called Pegasus testing pegcetacoplan, or APL-2, in paroxysmal nocturnal hemoglobinuria (PNH) “finally established that there is an important unmet medical need in this disease.”
