Regeneron and Teva Provide Update on Fasinumab Clinical Development Programs

- October 18th, 2016

Regeneron Pharmaceuticals and Teva Pharmaceutical Industries today provided an update on fasinumab, triggered by a recent development in a Phase 2b fasinumab study in patients with chronic low back pain.

Regeneron Pharmaceuticals, Inc. (NASDAQ:REGN) and Teva Pharmaceutical Industries Ltd. (NYSE and TASE:TEVA) today provided an update on fasinumab, triggered by a recent development in a Phase 2b fasinumab study in patients with chronic low back pain. Fasinumab is an investigational Nerve Growth Factor (NGF) antibody in clinical development for osteoarthritis pain and chronic low back pain.
Chronic Low Back Pain Program Update
The U.S. Food and Drug
Administration (FDA) has placed the Phase 2b study in chronic low back
pain on clinical hold and requested an amendment of the study protocol
after observing a case of adjudicated arthropathy in a patient receiving
high dose fasinumab who had advanced osteoarthritis at study entry. As a
result of the FDA decision, Regeneron completed an unplanned interim
review of results and has stopped dosing in the study. The unplanned
analysis showed clear evidence of efficacy with improvement in pain
scores in all fasinumab groups compared to placebo at the 8- and 12-week
time points (nominal p-value less than 0.01). Preliminary safety results
are generally consistent with what has been previously reported with the
class. The Phase 2b chronic low back pain study enrolled approximately
70 percent of the targeted 800 patients in four dose groups: placebo,
6mg subcutaneously monthly, 9mg subcutaneously monthly and 9mg
intravenously every two months. Regeneron has notified health
authorities and study investigators about the decision. Patients will
continue to be followed for up to 36 weeks.
Based on these results, Regeneron and Teva plan to design a pivotal
Phase 3 study in chronic low back pain that excludes patients with
advanced osteoarthritis. The companies plan to submit a pivotal program
plan for review with the FDA and other health authorities.
Osteoarthritis Pain Program Update
Sixteen week positive
results from the fasinumab Phase 2/3 osteoarthritis pain study in 421
patients were previously
reported
. Patients received their last dose at 12 weeks and a
follow-up analysis occurred at 36 weeks. The study incorporated
extensive imaging and analyses at baseline and during the study of index
and non-index joints, with particular focus on arthropathies including
subchondral insufficiency fractures (SIF), osteonecrosis (ON) and
rapidly progressive osteoarthritis (RPOA). At the 36-week analysis, the
incidence of adjudicated arthropathies was found to be potentially
dose-dependent, with a higher rate of patients experiencing
arthropathies in the higher dose groups [12 percent (9mg), 7 percent
(6mg), 5 percent (3mg), 2 percent (1mg) and 1 percent (placebo)]. Based
on these data, the companies are planning to advance only lower doses in
the ongoing fasinumab osteoarthritis pivotal Phase 3 program, subject to
discussion with the FDA and other health authorities.
Updated data from the osteoarthritis pain Phase 2/3 study and the
chronic low back pain Phase 2b study will be presented at upcoming
medical congresses.
“We are making data-driven decisions on Phase 3 fasinumab dosing that we
believe will maximize potential benefit for patients in need, while
minimizing the likelihood of side effects,” said George D. Yancopoulos,
M.D., Ph.D., Chief Scientific Officer, Regeneron and President,
Regeneron Laboratories. “We look forward to working with global health
authorities to advance this important investigational therapy for
patients with often difficult-to-treat osteoarthritis pain and chronic
low back pain.”
“We believe fasinumab represents an important potential innovation for
patients with osteoarthritis pain and chronic low back pain who
currently have clear unmet need and limited treatment options,” said
Michael Hayden, M.D., Ph.D., President of Global R&D and Chief
Scientific Officer at Teva. “We look forward to advancing clinical
development for this promising novel therapy.”
Regeneron and Teva are collaborating on the global development and
commercialization of fasinumab. Under a separate agreement with
Regeneron, Mitsubishi Tanabe Pharma has exclusive development and
commercial rights to fasinumab in Japan, Korea and nine other Asian
countries.

This release contains
forward-looking statements, which are based on management’s current
beliefs and expectations and involve a number of known and unknown risks
and uncertainties that could cause our future results, performance or
achievements to differ significantly from the results, performance or
achievements expressed or implied by such forward-looking statements.
Important factors that could cause or contribute to such differences
include risks relating to: our ability to develop and commercialize
additional pharmaceutical products; competition for our specialty
products, especially Copaxone
® (which faces
competition from orally-administered alternatives and a generic
version); our ability to integrate Allergan plc’s worldwide generic
pharmaceuticals business (“Actavis Generics”) and to realize the
anticipated benefits of the acquisition (and the timing of realizing
such benefits); the fact that following the consummation of the Actavis
Generics acquisition, we are dependent to a much larger extent than
previously on our generic pharmaceutical business; potential
restrictions on our ability to engage in additional transactions or
incur additional indebtedness as a result of the substantial amount of
debt incurred to finance the Actavis Generics acquisition; the fact that
for a period of time following the Actavis Generics acquisition, we will
have significantly less cash on hand than previously, which could
adversely affect our ability to grow; the possibility of material fines,
penalties and other sanctions and other adverse consequences arising out
of our ongoing FCPA investigations and related matters; our ability to
achieve expected results from investments in our pipeline of specialty
and other products; our ability to identify and successfully bid for
suitable acquisition targets or licensing opportunities, or to
consummate and integrate acquisitions; the extent to which any
manufacturing or quality control problems damage our reputation for
quality production and require costly remediation; increased government
scrutiny in both the U.S. and Europe of our patent settlement
agreements; our exposure to currency fluctuations and restrictions as

or breaches of our data security; competition for our specialty
pharmaceutical businesses from companies with greater resources and
capabilities; the impact of continuing consolidation of our distributors
and customers; decreased opportunities to obtain U.S. market exclusivity
for significant new generic products; potential liability in the U.S.,
Europe and other markets for sales of generic products prior to a final
resolution of outstanding patent litigation; our potential exposure to
product liability claims that are not covered by insurance; any failure
to recruit or retain key personnel, or to attract additional executive
and managerial talent; any failures to comply with complex Medicare and
Medicaid reporting and payment obligations; significant impairment
charges relating to intangible assets, goodwill and property, plant and
equipment; the effects of increased leverage and our resulting reliance
on access to the capital markets; potentially significant increases in
tax liabilities; the effect on our overall effective tax rate of the
termination or expiration of governmental programs or tax benefits, or
of a change in our business; variations in patent laws that may
adversely affect our ability to manufacture our products in the most
efficient manner; environmental risks; and other factors that are
discussed in our Annual Report on Form 20-F for the year ended December
31, 2015 and in our other filings with the U.S. Securities and Exchange
