Alnylam Supports Bleeding Disorders Month and World Hemophilia Day

Alnylam Supports Bleeding Disorders Month and World Hemophilia Day

“Bleeding Disorders Awareness Month,” was recently approved by the U.S. Department of Health and Human Services (HHS) as a National Health Observance in March. In previous years, March was dedicated to Hemophilia Awareness but through this new initiative, it has been expanded to unite the community and raise awareness of all inherited bleeding disorders and their potential health problems.

Behind the Mystery: Rare + Genetic Series - TTR Amyloid

Behind the Mystery: Rare & Genetic Series - TTR Amyloid

Battling a rare medical condition, that's often misdiagnosed.
Imagine having a rare, debilitating disease that's passed down through families. Dr. John Berk, Associate Professor of Medicine at Boston University and Clinical Director of its Amyloidosis Center, joins us to discuss the medical condition called Transthyretin-Mediated Amyloidosis. It's symptoms are similar to other conditions and ATTR patients are very often misdiagnosed. We discuss symptoms, family connections and treatment options, in this Behind the Mystery: Rare & Genetic segment. And meet Dylan Duncan, who's battling the disease. You don't want to miss this.

Initial Data in Paroxysmal Nocturnal Hemoglobinuria Patients from Ongoing Phase 1/2 Clinical Study with ALN-CC5 Support Potential for Eculizumab Sparing and Improved Disease Control for Eculizumab Inadequate Responders

Initial Data in Paroxysmal Nocturnal Hemoglobinuria Patients from Ongoing Phase 1/2 Clinical Study with ALN-CC5 Support Potential for Eculizumab Sparing and Improved Disease Control for Eculizumab Inadequate Responders

We reported data from 6 patients with Paroxysmal Nocturnal Hemoglobinuria (PNH) enrolled in Part C of our ongoing Phase 1/2 clinical study with ALN-CC5, an investigational RNAi therapeutic targeting complement component 5 (C5) for the treatment of complement-mediated diseases. These data were presented at the 21st Congress of the European Hematology Association (EHA) Meeting in Copenhagen, Denmark, held June 9-12, 2016.  In this part of the study, ALN-CC5 was evaluated as a monotherapy or as an adjunct to eculizumab, an approved anti-C5 monoclonal antibody indicated for the treatment of PNH.

Updated Healthy Volunteer Data from Phase 1/2 Clinical Study with ALN-CC5 for the Treatment of Complement-Mediated Diseases

Updated Healthy Volunteer Data from Phase 1/2 Clinical Study with ALN-CC5 for the Treatment of Complement-Mediated Diseases

We reported updated data from our ongoing Phase 1/2 clinical study with ALN-CC5, an investigational RNAi therapeutic targeting complement component C5 for the treatment of complement-mediated diseases. Data were presented at the 53rd Congress of the European Renal Association – European Dialysis and Transplant Association (ERA-EDTA) in Vienna, Austria, held May 21-24, 2016.  Results showed that administration of ALN-CC5 in healthy volunteers (N=44) achieved up to 99% knockdown of serum C5 and a mean maximum of 86% serum hemolysis inhibition in the highest dose group, with mean levels consistently greater than 80% inhibition through the 13 weeks of treatment. Results also showed a mean maximum CH50 inhibition of 99.6% and maximum inhibition up to 100% relative to baseline.

The effects of ALN-CC5 were found to be highly durable, with C5 knockdown clamped at over 90% for more than six months following a single dose. C5 knockdown and complement inhibition results support the potential for a once-quarterly dosing regimen when used in combination with the monoclonal antibody, eculizumab. Importantly, ALN-CC5 was shown to be generally well tolerated, with no serious adverse events and no drug-related discontinuations to date. All adverse events were mild or moderate in severity.

Complete 18-Month Data from Ongoing Phase 2 OLE Study with Patisiran in Development for the Treatment of Hereditary TTR-Mediated Amyloidosis with Polyneuropathy (hATTR-PN)

Complete 18-Month Data from Ongoing Phase 2 OLE Study with Patisiran in Development for the Treatment of Hereditary TTR-Mediated Amyloidosis with Polyneuropathy (hATTR-PN)

We reported results from our ongoing Phase 2 open-label extension (OLE) study with patisiran at the 68th Annual Meeting of the American Academy of Neurology (AAN), held April 15 – 21, 2016 in Vancouver, British Columbia, Canada.  Complete 18-month data (N=27) from the study provided continued evidence that patisiran has the potential to halt neuropathy progression in patients with hATTR-PN (also known as familial amyloidotic polyneuropathy, or FAP), showing a mean 0.8-point decrease in mNIS+7, which compares favorably to an estimated increase in mNIS+7 of 22 to 26 points at 18 months based upon analysis of historical data sets in untreated hATTR-PN patients with similar baseline neurologic impairment. Patisiran administration was also associated with a statistically significant, approximately 77% median improvement in nerve fiber density as read histologically in a blinded manner from distal thigh sweat gland biopsy samples.

Further, in the first reported exploratory analysis of its kind, the degree of TTR knockdown observed in patients was shown to correlate with improvement in mNIS+7 scores, supporting the therapeutic hypothesis that reduction of mutant and wild-type TTR may be associated with potential halting of neuropathy progression in patients with hATTR-PN.

Importantly, patisiran was found to be generally well tolerated out to 25 months of treatment.  There were no drug-related severe adverse events (SAEs), and the majority of reported adverse events (AEs) were mild to moderate.  The most common drug-related or possibly drug-related AEs were flushing (22.2%) and infusion-related reactions, or “IRRs” (18.5%). All IRRs and drug-related flushing AEs were mild in severity and did not result in any discontinuations.  In addition, there were no clinically significant changes in liver function tests, renal function tests, or other laboratory or hematologic parameters, including platelets.

New Program Added to Genetic Medicines Pipeline: ALN-F12

New Program Added to Genetic Medicines Pipeline: ALN-F12

We’re announcing the addition of a new program to our genetic medicines pipeline, ALN-F12, an investigational RNAi therapeutic targeting F12 for the treatment of Hereditary Angioedema (HAE). Pre-clinical data for ALN-F12 were presented at the American Academy of Allergy, Asthma & Immunology (AAAAI) Annual meeting, held March 4-7, 2016.

HAE is a genetic disorder characterized by episodes of severe swelling in various parts of the body, including the face, hands, feet, gastrointestinal tract, and airways. It is caused by a defect in the C1-inhibitor gene that results in poor control of contact pathway activation and excessive bradykinin generation. Elevated levels of bradykinin increase vascular permeability, ultimately causing the episodic swelling attacks that are characteristic of HAE. The F12 gene encodes Factor XII (FXII), which is at the top of the contact pathway cascade. Pre-clinical data showed that administration of ALN-F12 resulted in dose-dependent reduction of vascular permeability in two different mouse models of bradykinin-driven vascular leakage, demonstrating that suppression of F12 mRNA has the potential to mitigate excess bradykinin stimulation. Further, in non-human primates, a single subcutaneous dose of ALN-F12 at 3 mg/kg resulted in potent and durable knockdown of serum FXII of greater than 85 percent, with knockdown of over 50 percent sustained out to three months following administration.
