Paris, France and Cambridge, MA - November 2, 2017 - Sanofi Genzyme, the
specialty care global business unit of Sanofi, and Alnylam Pharmaceuticals, Inc.
(Nasdaq:ALNY), the leading RNAi therapeutics company, announced today positive
complete results from the APOLLO Phase 3 study of patisiran, an investigational
RNAi therapeutic being developed for patients with hereditary ATTR (hATTR)
amyloidosis with polyneuropathy.
These clinical data were presented today in an oral presentation at the 1st
European ATTR Amyloidosis Meeting for Patients and Doctors being held November
2-3, 2017 in Paris, France. Based on these results, Alnylam intends to file a
new drug application (NDA) in the United States for patisiran by end-2017 and a
marketing authorization application (MAA) in the European Union shortly
thereafter.
The full APOLLO results showed improvement with patisiran relative to placebo in
the primary endpoint of modified Neuropathy Impairment Score +7 (mNIS+7) and
additional secondary endpoints encompassing sensory, motor, and autonomic
neuropathy symptoms, as well as in exploratory cardiac endpoints, at 18 months.
Patients exhibited improved quality of life, activities of daily living,
nutritional status, motor strength, and ambulatory ability, with reduced disease
symptoms and disability. Favorable effects of patisiran relative to placebo were
observed across subgroups defined by demographic and baseline hATTR amyloidosis
disease characteristics. In a pre-specified cardiac subpopulation, significant
positive effects were observed for patisiran on certain exploratory cardiac
biomarker and echocardiographic endpoints.
The most commonly reported adverse events (AEs) that occurred more frequently in
patisiran-treated patients were generally mild to moderate and included
peripheral edema and infusion-related reactions (IRRs). The frequency of deaths
and serious adverse events (SAEs) was similar in the patisiran and placebo
groups. These data support the potential of patisiran to stabilize and even
improve the cardinal, multi-system disease manifestations of hATTR amyloidosis,
including improvement in patients' quality of life.
"We are very pleased for patients and families living with hATTR amyloidosis as
we believe these results from APOLLO offer new hope for the treatment of this
devastating disease. Indeed, patisiran holds the potential to halt or improve
neurological impairment and broader disease features in patients with hATTR
amyloidosis. We also view these results as a landmark achievement for the field
of RNAi therapeutics, as we believe they demonstrate the transformational
potential of this novel class of innovative medicines," said Akshay Vaishnaw,
M.D., Ph.D., Executive Vice President of R&D at Alnylam. "Alnylam is indebted to
all the patients, investigators, and study staff who took part in the APOLLO
study, making this important and notable milestone possible. We're also grateful
to the caregivers and family members whose support of APOLLO patients was such
an important contribution. With these promising APOLLO data in hand, we intend
to start filing our results with regulatory authorities in late 2017 with the
goal of achieving approval in mid-2018."
Overall Efficacy Results
Patisiran met the primary endpoint of mNIS+7 change from baseline at 18 months
relative to placebo, and all secondary study endpoints. Specifically:
* Patisiran treatment (N=148) resulted in a negative 6.0 point mean change
(improvement) in mNIS+7 score from baseline at 18 months as compared to a
28.0 point mean increase (worsening) reported for the placebo group (N=77),
resulting in a 34.0 point mean difference relative to placebo (p=9.26 x
10(-24)).
* The results were found to be consistent across all sub-components of the
mNIS+7 scale.
* Improvement in mNIS+7 from patisiran treatment was also consistently
observed across all defined patient subgroups, including age, sex, race,
geographic region, baseline neuropathy impairment, genotype, prior TTR
stabilizer use, baseline familial amyloid polyneuropathy (FAP) stage,
and inclusion in the pre-specified cardiac subpopulation.
* Patisiran treatment resulted in a negative 6.7 point mean change
(improvement) in Norfolk-Quality of Life-Diabetic Neuropathy (Norfolk QOL-
DN) score from baseline at 18 months as compared to a 14.4 point mean
increase (worsening) reported for the placebo group, resulting in a mean
21.1 point difference relative to placebo (p=1.10 x 10(-10)).
* Improvements in mNIS+7 and Norfolk QOL-DN with patisiran were also seen at
nine months, the earliest time point for these measurements in the study
with a mean 16.0 and a mean 15.0 point difference observed, respectively,
relative to placebo.
* In a pre-specified binary analysis of neurological improvement, 56 percent
(95 percent CI: 48.1, 64.1) of patisiran patients had an improvement in
mNIS+7 (less than 0 point change compared to baseline at 18 months), while
4 percent (95 percent CI: 0.0, 8.2) of placebo patients had an improvement
(p=1.82 x 10(-15)).
* Similarly, 51 percent (95 percent CI: 43.3, 59.4) of patisiran patients had
an improvement in Norfolk QOL-DN (less than 0 point change compared to
baseline at 18 months), versus 10 percent (95 percent CI: 3.6, 17.2) for
placebo (p=1.95 x 10(-10)).
* Patisiran also demonstrated statistically significant and clinically
meaningful improvements over placebo in all other secondary endpoints at 18
months, including: NIS-W (p=1.40 x 10(-13)), the subdomain of mNIS+7
assessing muscle strength; Rasch-built Overall Disability Scale (R-ODS)
(p=4.07 x 10(-16)), a patient reported outcome measure of daily living and
disability; timed ten-meter walk test (10-MWT) (p=1.88 x 10(-12)), assessing
ambulatory ability and gait speed; modified body mass index (mBMI) (p=8.83 x
10(-11)), assessing nutritional status; and, COMPASS-31 (p=0.0008), a
patient questionnaire assessing autonomic disease symptoms.
Cardiac Subpopulation Results
Favorable and significant changes in several exploratory cardiac measures,
including N-terminal pro b-type natriuretic peptide (NT-proBNP), certain
echocardiographic parameters, and 10-MWT were reported in patisiran-treated
patients in the pre-specified cardiac subpopulation*. Specifically:
* Patisiran treatment resulted in a median decrease (improvement) of 49.9
pg/ml in NT-proBNP levels as compared to a median increase (worsening) of
320 pg/ml reported for the placebo arm at 18 months (nominal p=7.74 x
10(-8), based on analysis of log-transformed values).
* Regarding echocardiographic measures, patisiran treatment resulted in a mean
0.93 mm reduction (improvement) in left ventricular (LV) wall thickness
(nominal p=0.0173) and a mean absolute 1.37 percent improvement in
longitudinal strain (nominal p=0.0154) relative to placebo.
* Regarding functional measures in the cardiac subpopulation, patisiran
treatment resulted in a 0.35 m/sec increase (improvement) in 10-MWT (nominal
p=7.42 x 10(-9)) relative to placebo at 18 months.
* Changes relative to baseline were also measured for troponin-I, LV mass, and
LV ejection fraction but were not statistically significant.
"Patients with hATTR amyloidosis are afflicted with an aggressive, rapidly
progressing, debilitating and fatal disease, and have a profound need for
effective and safe treatment options," said David Adams, M.D., Ph.D., Department
of Neurology, Bicetre hospital, Greater Paris University Hospitals, AP-HP and
Principal Investigator for the APOLLO trial. "The exciting APOLLO data that were
released today demonstrate the potential of patisiran to alleviate the multiple
neurological, cardiac, and autonomic manifestations of the disease. If approved,
I believe that patisiran could have a tremendous impact for patients and
physicians in the amyloidosis community. As a clinician, it has been deeply
rewarding to see the potential impact patisiran may have on the lives of hATTR
patients."
Safety and Tolerability
Patisiran showed an encouraging safety and tolerability profile relative to
placebo with up to 18 months of dosing. Specifically:
* The most commonly reported AEs that occurred more frequently in patisiran
patients were peripheral edema (29.7 percent versus 22.1 percent in placebo)
and IRRs (18.9 percent versus 9.1 percent in placebo). These were generally
mild to moderate in severity and only one patient discontinued due to an IRR
(0.7 percent).
* Compared to placebo, patisiran treatment was associated with fewer treatment
discontinuations (4.7 versus 14.3 percent) and fewer study withdrawals (4.7
versus 11.7 percent) due to AEs.
* The incidence of SAEs across the patisiran (36.5 percent) and placebo (40.3
percent) groups was similar.
* SAEs reported in 2 or more patients in the patisiran group included:
diarrhea (5.4 percent), cardiac failure, congestive cardiac failure,
orthostatic hypotension, pneumonia, and atrioventricular block complete
(2 percent each). These were all considered unrelated to patisiran,
except for one SAE of diarrhea. SAEs occurred with similar frequency in
the placebo group, except for diarrhea (1.3 percent in placebo group).
* Deaths were recorded with a similar incidence across the patisiran (4.7
percent) and placebo (7.8 percent) treatment groups.
* No deaths were considered related to study drug.
* There were no safety signals with regard to hepatic or renal function, or
evidence of thrombocytopenia, due to patisiran.
* Patisiran also showed an encouraging tolerability profile in the pre-
specified cardiac subpopulation, with a similar frequency of AEs in the
patisiran and placebo arms and a numerically lower incidence of SAEs (34.4
percent for patisiran versus 50.0 percent for placebo). The frequency of
deaths was 5.6 percent for patisiran versus 11.1 percent for placebo.
"The APOLLO data presented in Paris provide robust evidence supporting the
potential of RNAi as a novel therapeutic approach for patients with hATTR
amyloidosis," said Elias Zerhouni, M.D., President, Global R&D, Sanofi. "In this
study, patisiran's effect in helping to alleviate neurological impairment and
improve the quality of life for people living with this debilitating rare
disease is a remarkable accomplishment. Sanofi looks forward to coordinating
global regulatory submissions with Alnylam on an expedited basis."
Phase 2 Open-Label Extension (OLE) Study Results Over 36 Months
Sanofi Genzyme and Alnylam also announced today 36 month results from patients
originally in the patisiran Phase 2 OLE study. Specifically:
* Nearly all patients who were originally treated in the Phase 2 OLE study
have continued to receive patisiran in the Global OLE study.
* 25 patients who received 24 months of treatment in the Phase 2 OLE were
followed for an additional mean 16.2 months in the Global OLE study.
* There were no new safety concerns with additional dosing.
* The majority of AEs were mild or moderate in severity.
* Related AEs in two or more patients were IRRs (8.0 percent).
* For the 24 patients who have completed 36 months of treatment, the clinical
activity of patisiran was maintained, with a negative 4.1 point mean change
(improvement) in the mNIS+7 score relative to baseline.
