Alnylam Initiates ILLUMINATE-B Phase 3 Pediatric Study of Lumasiran for the Treatment of Primary Hyperoxaluria Type 1 and Presents New Positive Results from Phase 2 Open-Label Extension Study
Apr 15, 2019
− All Patients in Phase 1/2 Study Have Now Transitioned into Phase 2 OLE –
− Lumasiran Treatment Resulted in 72 Percent Mean Maximal Reduction in Urinary Oxalate Relative to Phase 1/2 Baseline –
The Company also announced new positive efficacy results from the
ongoing Phase 2 open-label extension (OLE) study of lumasiran. The
results were presented at the
“We are pleased to start the ILLUMINATE-B pediatric trial, an important
step forward in our goal to assess the safety and efficacy of lumasiran
across the PH1 age and disease severity continuum, including patients in
early infancy. This study adds to our overall clinical development plan
for lumasiran, led by our ILLUMINATE-A pivotal study with results
expected by year-end 2019,” said
All patients (N=20) from the Phase 1/2 study of lumasiran have now
transitioned to the Phase 2 OLE study designed to evaluate long-term
safety and efficacy of lumasiran. The new Phase 2 OLE results were
reported with 18 patients dosed in the OLE as of the data cut-off date
of
There were no discontinuations from study treatment. A single patient (1/18; 5.6 percent) reported two serious adverse events (SAEs) of traumatic brain injury and bone contusion sustained in a car accident; neither was assessed as related to study drug. Adverse events (AEs) were reported in 12/18 (66.7 percent) patients. Injection site reactions were reported in 3/18 (16.7 percent) patients; all were mild and assessed as related to study drug. There were no clinically significant laboratory changes.
Lumasiran demonstrated a 72 percent mean maximal reduction (range: 41-90 percent) in urinary oxalate excretion relative to Phase 1/2 baseline values across all dose cohorts (N=9). The mean reduction relative to baseline at Day 85 was 69 percent (N=7). Lumasiran also demonstrated a mean maximal reduction in urinary 24-hour oxalate:creatinine ratio of 77 percent (range: 57-91 percent) relative to Phase 1/2 baseline values across all dose cohorts (N=10). The mean reduction relative to baseline at Day 85 was 70 percent (N=9).

About ILLUMINATE-B Phase 3 Study
The ILLUMINATE-B Phase 3
trial is an open-label, global, multicenter study to evaluate the
efficacy and safety of lumasiran in approximately eight patients less
than six years of age with a documented diagnosis of PH1. Dosing regimen
will be based on patient weight. The primary endpoint is the reduction
of urinary oxalate at six months relative to baseline. Key secondary and
exploratory endpoints will evaluate additional measures of urinary
oxalate, estimated glomerular filtration rate (eGFR), safety and
tolerability, and quality of life. For more information on ILLUMINATE-B

About Lumasiran
Lumasiran (formerly known as ALN-GO1) is an
investigational RNAi therapeutic targeting glycolate oxidase (GO) in
development for the treatment of Primary Hyperoxaluria Type 1 (PH1).
Lumasiran is designed to reduce hepatic levels of the GO enzyme, thereby
depleting the substrate necessary for the production of oxalate – the
metabolite that directly contributes to the pathophysiology of PH1.
Lumasiran utilizes Alnylam's Enhanced Stabilization Chemistry
(ESC)-GalNAc-conjugate technology, which enables subcutaneous dosing
with increased potency and durability and a wide therapeutic index.
Lumasiran has received both U.S. and EU Orphan Drug Designations, a
Breakthrough Therapy Designation from the U.S. Food and Drug
Administration (
About Primary Hyperoxaluria Type 1 (PH1)
PH1 is an
ultra-orphan disease in which excessive oxalate production results in
the deposition of calcium oxalate crystals in the kidneys and urinary
tract and can lead to the formation of painful and recurrent kidney
stones and nephrocalcinosis. Renal damage is caused by a combination of
tubular toxicity from oxalate, calcium oxalate deposition in the
kidneys, and urinary obstruction by calcium oxalate stones. Compromised
kidney function exacerbates the disease as the excess oxalate can no
longer be effectively excreted, resulting in subsequent accumulation and
crystallization in bones, eyes, skin, and heart, leading to severe
illness and death. Current treatment options are very limited and
include frequent renal dialysis or combined organ transplantation of
liver and kidney, a procedure with high morbidity that is limited due to
organ availability. Although a small minority of patients respond to
Vitamin B6 therapy, there are no approved pharmaceutical therapies for
PH1.
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 new class
of medicines, known as RNAi therapeutics, is now a reality. 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 (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, hepatic
infectious, and central nervous system (CNS)/ocular 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. Alnylam’s first U.S.
