NEW HAVEN, Conn., Oct. 24, 2017 (GLOBE NEWSWIRE) -- Achillion Pharmaceuticals, Inc.
(Nasdaq:ACHN) today announced that the U.S. Patent and Trademark Office (USPTO) has issued a U.S. Patent to Achillion for ACH-4471.
U.S. Patent No. 9,796,741, entitled “Aryl, Heteroaryl, and Heterocyclic Compounds for Treatment of Complement Mediated Disorders,”
has been granted with claims to compositions of matter for ACH-4471 and additional compounds that inhibit complement factor D
activity, a key mediator in the complement alternative pathway (AP). This issued patent will be the eighth patent that the USPTO
has granted to Achillion this year on its complement factor D portfolio. Achillion currently has over one hundred global patent
applications and patents covering its complement-related research program.
“We are very pleased with the granting of this composition of matter patent for our first-in-class, oral
complement factor D inhibitor, ACH-4471,” commented Milind Deshpande, Ph.D., President and Chief Executive Officer of Achillion.
“As a leader in complement alternative pathway biology, we are building upon the recently reported efficacy data from our ongoing
phase 2 trial with ACH-4471 for untreated PNH, and look forward to reporting the ongoing phase 2 14-day trial of ACH-4471 for
patients with C3G / IC-MPGN.”
About the Achillion Alternative Pathway Complement Factor D Platform
Achillion has leveraged its internal discovery capabilities and a novel complement-related drug development platform to develop
small molecule factor D inhibitor compounds that target the complement AP. Factor D is an essential serine protease involved in the
AP, a part of the innate immune system. Achillion's complement platform is focused on seeking to advance small molecule compounds
that inhibit factor D and can potentially be used in the treatment of immune-related diseases in which the AP plays a critical
role. Potential indications currently being evaluated for these compounds include paroxysmal nocturnal hemoglobinuria (PNH), C3
glomerulopathy (C3G), immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN), and geographic atrophy (GA), an
advanced form of dry age-related macular degeneration (dry AMD).
