Diroximel Fumarate Demonstrated Significantly Improved
Gastrointestinal Tolerability Profile Compared to Dimethyl Fumarate
in Patients with Multiple Sclerosis
Alkermes plc (Nasdaq: ALKS) and Biogen Inc. (Nasdaq: BIIB) today
announced positive topline results from EVOLVE-MS-2, a large,
randomized, double-blind, five-week, Phase 3 study of diroximel
fumarate, an investigational, novel oral fumarate with a distinct
chemical structure, for relapsing-remitting multiple sclerosis
(RRMS), compared to TECFIDERA® (dimethyl fumarate). Diroximel
fumarate was statistically superior to dimethyl fumarate on the
study’s pre-specified primary endpoint, with patients treated with
diroximel fumarate self-reporting significantly fewer days of key
gastrointestinal (GI) symptoms with intensity scores ≥2 on the
Individual Gastrointestinal Symptom and Impact Scale (IGISIS), as
compared to dimethyl fumarate (p=0.0003).
The most common adverse events (AEs) reported in the study for
both treatment groups were flushing, diarrhea and nausea (32.8%,
15.4% and 14.6% for diroximel fumarate; 40.6%, 22.3% and 20.7% for
dimethyl fumarate). The overall proportion of patients with AEs
leading to study discontinuation were 1.6% for diroximel fumarate
and 6.0% for dimethyl fumarate. Of those, the proportion of
patients who discontinued due to GI adverse events during the
five-week treatment period were 0.8% for diroximel fumarate and
4.8% for dimethyl fumarate. Further analysis of the data from the
EVOLVE-MS-2 study is ongoing and will be presented at a future
scientific forum.
“As part of our leadership in multiple sclerosis, Biogen has
long understood that the disease differs from person to person, as
well as throughout the course of the disease. We are committed to
offering a range of options to patients to meet their needs,” said
Michael Ehlers, executive vice president, research &
development at Biogen. “These data build on the foundation we have
created with TECFIDERA, the most prescribed oral MS therapy
worldwide, and further demonstrate the potential of diroximel
fumarate as a novel oral fumarate within our MS portfolio.”
“Diroximel fumarate demonstrated statistically superior GI
tolerability compared to dimethyl fumarate on the EVOLVE-MS-2
study’s primary endpoint, as well as a low discontinuation rate of
less than 1% due to GI adverse events. These results reinforce the
safety and tolerability profile diroximel fumarate has consistently
demonstrated across the EVOLVE-MS development program, underscoring
the potential importance of diroximel fumarate for the treatment of
people living with relapsing-remitting MS. We look forward to the
FDA’s completion of its review of the diroximel fumarate NDA in the
fourth quarter,” said Craig Hopkinson, M.D., chief medical officer
and senior vice president of medicines development and medical
affairs at Alkermes.
EVOLVE-MS-2 was a Phase 3, multicenter, double-blind,
active-controlled, five-week study designed to evaluate the GI
tolerability, including duration and severity, of diroximel
fumarate 462 mg twice daily compared to dimethyl fumarate 240 mg
twice daily in 506 patients with RRMS. The study’s primary endpoint
assessed the number of days patients reported GI symptoms with a
symptom intensity score ≥2 on the IGISIS rating scale spanning 0
(not at all) through 10 (extreme). The IGISIS was completed twice
daily and evaluated the intensity of key GI symptoms, including
nausea, vomiting, upper and lower abdominal pain, and diarrhea.
“With a chronic disease like MS, interrupting or stopping
treatment due to GI side effects can often provoke the return of
disease activity. Physicians and patients should work together to
choose a medication that provides the right balance of efficacy,
safety and tolerability to help manage patients’ MS and meet their
treatment goals,” said Robert Naismith, M.D., professor of
neurology, Washington University School of Medicine in St. Louis.
“These topline results suggest that diroximel fumarate offers a
differentiated GI tolerability profile and may represent an
important new option for people living with relapsing MS.”
The EVOLVE-MS-2 study is part of the EVOLVE-MS diroximel
fumarate clinical development program, which is being conducted as
part of a worldwide development and commercialization agreement
between Alkermes and Biogen. Diroximel fumarate is currently under
review with the U.S. Food and Drug Administration (FDA) with a
PDUFA (Prescription Drug User Fee Act) target action date in the
fourth quarter of 2019. Biogen intends to market diroximel fumarate
under the conditionally approved brand name VUMERITY™.
About Diroximel Fumarate Diroximel fumarate is
an investigational, novel oral fumarate candidate with a distinct
chemical structure in development for the treatment of relapsing
forms of MS. Diroximel fumarate is designed to rapidly convert to
monomethyl fumarate in the body and, based on bioequivalence data,
is referencing TECFIDERA® (dimethyl fumarate) as part of the
505(b)(2) regulatory pathway. Diroximel fumarate is currently under
review with the U.S. Food and Drug Administration (FDA) with a
PDUFA (Prescription Drug User Fee Act) target action date in the
fourth quarter of 2019. If approved by the FDA, Biogen intends to
market diroximel fumarate under the conditionally approved brand
name VUMERITY™.
About the Diroximel Fumarate EVOLVE-MS Clinical
Development ProgramThe key components of the EVOLVE-MS
(Endeavoring to Advance Treatment
for Patients Living with
Multiple Sclerosis) clinical development program
of diroximel fumarate include the EVOLVE-MS-1 study, a Phase 3,
open-label, two-year safety study in relapsing-remitting MS
patients, along with pharmacokinetic bridging studies comparing
diroximel fumarate and dimethyl fumarate to demonstrate
bioequivalence. The EVOLVE-MS clinical development program also
includes EVOLVE-MS-2, a Phase 3, five-week randomized, prospective,
double-blind, multi-center study assessing the GI tolerability of
diroximel fumarate and dimethyl fumarate.
About TECFIDERA® (dimethyl fumarate) TECFIDERA
is the most prescribed oral medication for relapsing multiple
sclerosis (MS) in the world and has been shown to reduce the rate
of MS relapses, slow the progression of disability and impact the
number of MS brain lesions, while demonstrating a
well-characterized safety profile in people with relapsing forms of
MS. TECFIDERA is approved in 69 countries and more than
398,000 patients have been treated with it, representing more than
740,000 patient-years of exposure across clinical trial use and
patients prescribed TECFIDERA. Of these, 6,335 patients (12,985
patient-years) were from clinical trials.[i] TECFIDERA is
indicated in the U.S. for the treatment of patients with relapsing
forms of MS, to include clinically isolated syndrome,
relapsing-remitting disease, and active secondary progressive
disease, in adults. TECFIDERA is approved in the European Union for
relapsing-remitting MS.
TECFIDERA is contraindicated in patients with a known
hypersensitivity to dimethyl fumarate or any of the excipients of
TECFIDERA. Rare cases of progressive multifocal
leukoencephalopathy, a rare opportunistic viral infection of the
brain which has been associated with death or severe disability,
have been seen with TECFIDERA patients in the setting of prolonged
lymphopenia although the role of lymphopenia in these cases is
uncertain. Other serious side effects include a decrease in mean
lymphocyte counts during the first year of treatment, which then
plateaued, and liver function abnormalities, which resolved upon
treatment discontinuation. In clinical trials, the most common
adverse events associated with TECFIDERA were flushing and
gastrointestinal (GI) events.
