CAMBRIDGE, Mass.--(BUSINESS WIRE)--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, announced today a successful Type A meeting with the U.S. Food and Drug Administration (FDA) where alignment was achieved on safety measures and a risk mitigation strategy to enable resumption of dosing in clinical studies with fitusiran, including the Phase 2 open-label extension (OLE) study and the ATLAS Phase 3 program. With the completion of the Type A meeting, the FDA will now consider removal of the clinical hold upon final review of the amended protocols and other trial materials. Fitusiran is an investigational RNAi therapeutic targeting antithrombin (AT) for the treatment of patients with hemophilia A and B, that is designed to lower levels of AT with the goal of promoting sufficient thrombin generation to restore hemostasis and prevent bleeding.
“We are pleased with the outcome of our meeting with the FDA regarding next steps for the fitusiran clinical program and remain committed to reinitiating the Phase 2 OLE and the Phase 3 ATLAS program around year-end,” said Akin Akinc, Ph.D., Vice President and General Manager, Fitusiran. “Further, we look forward to continuing our partnership with physicians and nurses to support education efforts on fitusiran safety, which we believe are a critical step when introducing a new therapeutic modality with the potential to address important unmet needs in hemophilia.”
The Company and the FDA reached alignment on new clinical risk mitigation measures, including protocol-specified guidelines and additional investigator and patient education concerning reduced doses of replacement factor or bypassing agent to treat any breakthrough bleeds in fitusiran studies.
About Fitusiran
Fitusiran is an investigational,
once-monthly, subcutaneously administered RNAi therapeutic targeting
antithrombin (AT) in development for the treatment of hemophilia A and
B, with and without inhibitors. Fitusiran also has the potential to be
used for rare bleeding disorders. Fitusiran is designed to lower levels
of AT with the goal of promoting sufficient thrombin generation to
restore hemostasis and prevent bleeding. Fitusiran utilizes Alnylam's
ESC-GalNAc conjugate technology, which enables subcutaneous dosing with
increased potency and durability. The clinical significance of this
technology is under investigation. In September 2017, Alnylam
temporarily suspended dosing in all ongoing studies of fitusiran
following the observation of a fatal thrombotic serious adverse event
that occurred in a patient with hemophilia A without inhibitors who was
receiving fitusiran in the Phase 2 OLE study. All ongoing studies were
placed on clinical hold. Alnylam and fitusiran study investigators and
the FDA have now aligned on safety measures and a risk management
strategy for further advancement of fitusiran. Following regulatory and
institutional review and approval of amended study protocols and other
clinical materials implementing these measures, Alnylam intends to
resume fitusiran studies as soon as possible.
Fitusiran has not been approved by the FDA, EMA or any other regulatory authority for any indication and no conclusions can or should be drawn regarding the safety or effectiveness of this investigational therapeutic.
About Hemophilia
Hemophilia is a hereditary bleeding
disorder characterized by an underlying defect in the ability to
generate adequate levels of thrombin needed for effective clotting,
thereby resulting in recurrent bleeds into joints, muscles, and major
internal organs. There are approximately 400,000 people living with
hemophilia A and hemophilia B worldwide.
Standard treatment for people with hemophilia currently involves replacement of the deficient clotting factor either as prophylaxis or "on-demand" therapy, which can lead to a temporary restoration of thrombin generation capacity. However, with current factor replacement treatments people with hemophilia are at risk of developing neutralizing antibodies or ‘inhibitors’ to their replacement factor, a very serious complication affecting as many as one third of people with hemophilia A and a smaller fraction of people with hemophilia B. People who develop inhibitors become refractory to replacement factor therapy and are twice as likely to be hospitalized for a bleeding episode.
Alnylam - Sanofi Genzyme Alliance
In January 2014,
Alnylam and Sanofi Genzyme, the specialty care global business unit
of Sanofi, formed an alliance to accelerate the advancement of RNAi
therapeutics as a potential new class of innovative medicines for
patients around the world with rare genetic diseases. The alliance
enables Sanofi Genzyme to expand its rare disease pipeline with
Alnylam's novel RNAi technology and provides access to Alnylam's R&D
engine, while Alnylam benefits from Sanofi Genzyme's proven global
capabilities to advance late-stage development and, upon
commercialization, accelerate market access for these promising genetic
medicine products.
In November 2016, Sanofi Genzyme elected to co-develop (through Sanofi R&D) and co-commercialize fitusiran in the United States, Canada and Western Europe, in addition to commercializing fitusiran in its rest of world territories.
About RNAi
RNAi (RNA interference) is a natural cellular
process of gene silencing that represents one of the most promising and
rapidly advancing frontiers in biology and drug development today. Its
discovery has been heralded as “a major scientific breakthrough that
happens once every decade or so,” and was recognized with the award of
the 2006 Nobel Prize for Physiology or Medicine. By harnessing the
natural biological process of RNAi occurring in our cells, a major new
class of medicines, known as RNAi therapeutics, is on the horizon. Small
interfering RNA (siRNA), the molecules that mediate RNAi and comprise
Alnylam's RNAi therapeutic platform, function upstream of today’s
medicines by potently silencing messenger RNA (mRNA) – the genetic
precursors – that encode for disease-causing proteins, thus preventing
them from being made. This is a revolutionary approach with the
potential to transform the care of patients with genetic and other
diseases.
About Alnylam Pharmaceuticals
Alnylam (Nasdaq: ALNY) is
leading the translation of RNA interference (RNAi) into a whole new
class of innovative medicines with the potential to transform the lives
of people afflicted with rare genetic, cardio-metabolic, and hepatic
infectious diseases. Based on Nobel Prize-winning science, RNAi
therapeutics represent a powerful, clinically validated approach for the
treatment of a wide range of severe and debilitating diseases. Founded
in 2002, Alnylam is delivering on a bold vision to turn scientific
possibility into reality, with a robust discovery platform and deep
