THOUSAND OAKS, Calif.,
March 13, 2017 /PRNewswire/
-- Amgen (NASDAQ: AMGN) today announced positive top-line
results from a Phase 3 study evaluating Repatha®
(evolocumab) in patients who were receiving apheresis to reduce
low-density lipoprotein cholesterol (LDL-C). The study met its
primary endpoint, demonstrating that treatment with Repatha
significantly reduced the need for LDL-C apheresis in adult
patients, as measured at the end of the randomized period. The
study also met its secondary endpoints of percent change from
baseline to week 4 in LDL-C, non-high-density lipoprotein
cholesterol (non-HDL-C) and total cholesterol:HDL-C ratio.
"Patients who require apheresis to help control their LDL-C have
limited treatment options and face the daunting challenge of
frequent, invasive and costly procedures," said Sean E. Harper, M.D., executive vice president
of Research and Development at Amgen. "These positive data suggest
patients may have an alternative option to help them manage their
cholesterol."
The overall incidence of treatment-emergent adverse events was
comparable among both groups. No new safety concerns were
identified in this study.
Detailed results will be submitted to a future medical
conference and for publication.
Apheresis is an invasive procedure similar to dialysis, in which
a special machine removes LDL-C from a patient's
plasma.1 The process can be time consuming and
burdensome for patients, as the weekly or bi-weekly treatments can
take between one to three hours. Many patients also travel long
distances for treatment as there are only approximately 60
apheresis centers in the United
States (U.S.).2
In the U.S., there are approximately 11 million people with
atherosclerotic cardiovascular disease (ASCVD) and/or familial
hypercholesterolemia (FH) who have uncontrolled levels of LDL-C
over 70 mg/dL, despite treatment with statins or other
cholesterol-lowering therapies.3,4
Study Design
Thirty-nine adult patients with LDL-C
levels between ≥100 mg/dL and ≤190 mg/dL despite regular weekly or
biweekly apheresis plus statin therapy (if tolerated) were
randomized to receive either Repatha subcutaneously every two weeks
or continue LDL-C apheresis (every one or two weeks, according to
their schedule before entering the study) for the first six weeks.
Beginning at week six, all patients were given Repatha. The primary
endpoint evaluated the efficacy of subcutaneous Repatha, compared
to regularly scheduled LDL-C apheresis, on reducing the need for
continued apheresis at the end of the randomized period. Secondary
endpoints measured the effects of Repatha compared with apheresis
at week four on levels of LDL-C, non-HDL-C and total
cholesterol:HDL-C ratio.
About
Repatha® (evolocumab)
Repatha® (evolocumab)
is a human monoclonal antibody that inhibits proprotein convertase
subtilisin/kexin type 9 (PCSK9). Repatha binds to PCSK9 and
inhibits circulating PCSK9 from binding to the low-density
lipoprotein (LDL) receptor (LDLR), preventing PCSK9-mediated LDLR
degradation and permitting LDLR to recycle back to the liver cell
surface. By inhibiting the binding of PCSK9 to LDLR, Repatha
increases the number of LDLRs available to clear LDL from the
blood, thereby lowering LDL-C levels.5
Repatha is approved in more than 40 countries, including the
U.S., Japan, Canada and in all 28 countries that are
members of the European Union. Applications in other countries
are pending.
Important U.S. Product
Information
Repatha® is indicated as an
adjunct to diet and:
- Maximally tolerated statin therapy for treatment of adults with
heterozygous familial hypercholesterolemia (HeFH) or clinical
atherosclerotic cardiovascular disease (ASCVD), who require
additional lowering of low-density lipoprotein cholesterol
(LDL-C)
- Other LDL-lowering therapies (e.g., statins, ezetimibe, LDL
apheresis) in patients with homozygous familial
hypercholesterolemia (HoFH) who require additional lowering of
LDL-C
The effect of Repatha® on cardiovascular
morbidity and mortality has not been determined.
The safety and effectiveness of Repatha® have
not been established in pediatric patients with HoFH who are
younger than 13 years old.
The safety and effectiveness of Repatha® have
not been established in pediatric patients with primary
hyperlipidemia or HeFH.
Important U.S. Safety Information
Contraindication: Repatha® is
contraindicated in patients with a history of a serious
hypersensitivity reaction to Repatha®.
Allergic reactions: Hypersensitivity reactions (e.g.
rash, urticaria) have been reported in patients treated with
Repatha®, including some that led to discontinuation of
therapy. If signs or symptoms of serious allergic reactions occur,
discontinue treatment with Repatha®, treat according to
the standard of care, and monitor until signs and symptoms
resolve.
Adverse reactions: The most common adverse reactions
(>5% of Repatha®-treated patients and more common
than placebo) were: nasopharyngitis, upper respiratory tract
infection, influenza, back pain, and injection site reactions.
In a 52-week trial, adverse reactions led to discontinuation of
treatment in 2.2% of Repatha®-treated patients and 1% of
placebo-treated patients. The most common adverse reaction that led
to Repatha® treatment discontinuation and occurred
at a rate greater than placebo was myalgia (0.3% versus 0% for
Repatha® and placebo, respectively).
Adverse reactions from a pool of the 52-week trial and seven
12-week trials: Local injection site reactions occurred in 3.2% and
3.0% of Repatha®-treated and placebo-treated patients,
respectively. The most common injection site reactions were
erythema, pain, and bruising. The proportions of patients who
discontinued treatment due to local injection site reactions in
Repatha®-treated patients and placebo-treated patients
were 0.1% and 0%, respectively.
Allergic reactions occurred in 5.1% and 4.7% of
Repatha®-treated and placebo-treated patients,
respectively. The most common allergic reactions were rash (1.0%
versus 0.5% for Repatha® and placebo,
respectively), eczema (0.4% versus 0.2%), erythema (0.4% versus
0.2%), and urticaria (0.4% versus 0.1%).
Neurocognitive events were reported in less than or equal to
0.2% in Repatha®-treated and placebo-treated
patients.
In a pool of placebo- and active-controlled trials, as well as
open-label extension studies that followed them, a total of 1,988
patients treated with Repatha® had at least one
LDL-C value <25 mg/dL. Changes to background lipid-altering
therapy were not made in response to low LDL-C values, and
Repatha® dosing was not modified or interrupted on
this basis. Although adverse consequences of very low LDL-C were
not identified in these trials, the long-term effects of very low
levels of LDL-C induced by Repatha® are
unknown.
Musculoskeletal adverse reactions were reported in 14.3% of
Repatha®-treated patients and 12.8% of placebo-treated
patients. The most common adverse reactions that occurred at a rate
greater than placebo were back pain (3.2% versus 2.9% for
Repatha® and placebo, respectively), arthralgia
(2.3% versus 2.2%), and myalgia (2.0% versus 1.8%).
Homozygous Familial Hypercholesterolemia (HoFH): In
49 patients with homozygous familial hypercholesterolemia studied
in a 12-week, double-blind, randomized, placebo-controlled trial,
33 patients received 420 mg of
Repatha® subcutaneously once monthly. The adverse
reactions that occurred in at least 2 (6.1%)
Repatha®-treated patients and more frequently than in
placebo-treated patients, included upper respiratory tract
infection (9.1% versus 6.3%), influenza (9.1% versus 0%),
gastroenteritis (6.1% versus 0%), and nasopharyngitis (6.1% versus
0%).
Immunogenicity: Repatha® is a human
monoclonal antibody. As with all therapeutic proteins, there is a
potential for immunogenicity with Repatha®.
