Teva Announces Launch of a Generic Version of Letairis® (ambrisentan) Tablets in the United States

JERUSALEM–(BUSINESS WIRE)–Teva Pharmaceutical Industries Ltd., (NYSE and TASE: TEVA) today
announced the launch of a generic version of Letairis®1
(ambrisentan) Tablets, 5 mg and 10 mg, in the U.S.

Ambrisentan is an endothelin receptor antagonist indicated for the
treatment of pulmonary arterial hypertension (PAH) (WHO Group 1) to
improve exercise ability and delay clinical worsening. In combination
with tadalafil, ambrisentan is indicated to reduce the risks of disease
progression and hospitalization for worsening PAH, and to improve
exercise ability. For all female patients, ambrisentan tablets are only
available through a restricted program called the Ambrisentan Risk
Evaluation & Mitigation Strategy (REMS) due to the risk of fetal harm.

“The launch of ambrisentan tablets in the U.S. is an important addition
to Teva’s growing generic portfolio of nearly 60 cardiovascular
medicines,” said Brendan O’Grady, EVP and Head of North America
Commercial. “Our ability to help treat this disease is a testament to
our commitment to providing affordable, generic treatment options to
people living with chronic, life-long conditions.”

With nearly 500 generic medicines available, Teva has the largest
portfolio of FDA-approved generic products on the market and holds the
leading position in first-to-file opportunities, with over 100 pending
first-to-files in the U.S. Currently, one in eight generic prescriptions
dispensed in the U.S. is filled with a Teva generic product.

Letairis® has annual sales of nearly $247 million in the
U.S., according to IQVIA data as of February 2019.

About Ambrisentan Tablets

Ambrisentan tablets are indicated for the treatment of pulmonary
arterial hypertension (PAH) (WHO Group 1) to improve exercise ability
and delay clinical worsening. In combination with tadalafil, ambrisentan
tablets are indicated to reduce the risks of disease progression and
hospitalization for worsening PAH, and to improve exercise ability.
Studies establishing effectiveness included predominantly patients with
WHO Functional Class II–III symptoms and etiologies of idiopathic or
heritable PAH (60%) or PAH associated with connective tissue diseases


WARNING: Embryo-Fetal Toxicity. Do not administer ambrisentan
to a pregnant female because it may cause fetal harm. Ambrisentan is
very likely to produce serious birth defects if used by pregnant
females, as this effect has been seen consistently when it is
administered to animals.
Exclude pregnancy before the initiation
of treatment with ambrisentan. Females of reproductive potential must
use acceptable methods of contraception during treatment with
ambrisentan and for one month after treatment. Obtain monthly pregnancy
tests during treatment and 1 month after discontinuation of treatment.

Because of the risk of embryo-fetal toxicity, females can only
receive ambrisentan through a restricted program called the Ambrisentan
REMS program.

Ambrisentan is contraindicated in patients with Idiopathic Pulmonary
Fibrosis (IPF), including IPF patients with pulmonary hypertension (WHO
Group 3). Peripheral edema is a known class effect of endothelin
receptor antagonists, and is also a clinical consequence of PAH and
worsening PAH. In the placebo-controlled studies, there was an increased
incidence of peripheral edema in patients treated with doses of 5 or 10
mg ambrisentan compared to placebo. Peripheral edema/fluid retention is
more common with ambrisentan plus tadalafil than with ambrisentan or
tadalafil alone. Acute pulmonary edema during initiation of therapy with
vasodilating agents, such as ambrisentan, could be the possibility of
pulmonary veno-occlusive disease.

Decreased sperm counts have been observed in human and animal studies
with another endothelin receptor antagonist and in animal fertility
studies with ambrisentan. Ambrisentan may have an adverse effect on
spermatogenesis. Decreases in hemoglobin concentration and
hematocrit have followed administration of other endothelin receptor
antagonists and were observed in clinical studies with ambrisentan.

In clinical trials, the most common adverse reactions for ambrisentan
(>3% compared to placebo) were peripheral edema, nasal congestion,
sinusitis, and flushing. When used in combination with tadalafil, most
common adverse reactions (>5% compared with either monotherapy) were
peripheral edema, headache, nasal congestion, cough, anemia, dyspepsia,
and bronchitis.
