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 (34%).
IMPORTANT SAFETY INFORMATION
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.
