Antares Pharma Announces FDA Approval of TEV-TROPIN(R) 10 mg (Human Growth Hormone) Needle-Free Injector

FDA Approves Name Change to ZOMACTON(TM)


EWING, N.J., March 31, 2015 (GLOBE NEWSWIRE) -- Antares Pharma, Inc. (Nasdaq:ATRS) today announced that Ferring Pharmaceuticals Inc. (Ferring) has received U.S. Food and Drug Administration (FDA) approval of a name change enabling its newly acquired recombinant human growth hormone to be marketed in the U.S. as ZOMACTON(somatropin [rDNA origin]) for injection, and the needle-free delivery system to be marketed in the U.S. as ZOMA-Jet. Ferring also received approval from the FDA to market the 10 mg needle-free injector device which, along with certain consumables, is supplied by Antares to Ferring. Ferring purchased the U.S. rights to ZOMACTON, formerly TEV-TROPIN®, and to ZOMA-Jet, formerly Tjet®, in December 2014 from Teva Pharmaceutical Industries Ltd. Ferring developed and has marketed ZOMACTON outside of the U.S. since 1988 and in 47 countries globally.

In the U.S., ZOMACTON is indicated for the treatment of children who have growth failure due to an inadequate secretion of normal endogenous growth hormone. Growth hormone deficiency (GHD) in children can lead to short stature and delayed puberty.1 An estimated one in 4,000 to 10,000 children has GHD, and with early detection and treatment, many of these children can reach a normal height.2

Because somatropin increases growth rate, patients with a history of scoliosis who are treated with somatropin should be monitored for progression of scoliosis. Somatropin may alter the clearance of drugs metabolized by the CP450 enzyme system and careful monitoring is advisable. The following adverse reactions have been observed during appropriate use of somatropin: headaches (children and adults), gynecomastia (children), and pancreatitis (children and adults). In studies of growth hormone-deficient children, injection-site reactions (e.g. pain, bruise) occurred in eight of the 164 treated patients. Leukemia and new-onset Type 2 diabetes mellitus have been reported.

"We are excited that Ferring will be adding this new 10 mg dosage form to the previously approved 5 mg strength," said Eamonn P. Hobbs, President and Chief Executive Officer of Antares Pharma.   "We are also pleased that the FDA has approved the use of another Antares device, which we believe continues to validate our technology and our approach to designing novel, product-specific injector devices that keep patients' needs in mind."

ZOMACTON is expected to be available in the U.S. in the second quarter of 2015 as both a 5 and 10 mg option, with the 10 mg dose in a pre-filled diluent syringe. In addition, the ZOMA-Jet needle-free administration device supplied by Antares is expected to be available for the 5 mg dose and in a new 10 mg dose later this year.

About ZOMACTON

ZOMACTON is indicated for the treatment of children who have growth failure due to an inadequate secretion of normal endogenous growth hormone.

Important Safety Information

ZOMACTON™ stimulates linear growth in children lacking endogenous GH. Treatment of growth hormone-deficient (GHD) children with ZOMACTONproduces growth rate and IGF-1 levels similar to those seen after treatment with hGH of pituitary origin.

Unless patients with Prader-Willi Syndrome (PWS) also have a diagnosis of GHD, ZOMACTONis not indicated for treatment of pediatric patients who have growth failure due to genetically confirmed PWS. Because of reported fatalities, patients with PWS who are severely obese, have severe respiratory impairment, respiratory infections, or sleep apnea should interrupt use of GH.

Cases of pancreatitis have been reported rarely in children and adults receiving somatropin treatment. Pancreatitis should be considered in any somatropin-treated patient, especially a child, who develops persistent, severe abdominal pain.

Patients should be observed for evidence of Type 2 diabetes mellitus, glucose intolerance, hypopituitarism, malignant transformation of skin lesions, hypothyroidism, slipped capital femoral epiphysis and intracranial hypertension. Funduscopic examination of patients is recommended at the initiation and periodically during the course of GH treatment. ZOMACTONshould not be initiated in patients with acute critical illness as a complication of open heart surgery, abdominal surgery, multiple accidental trauma, or those with acute respiratory failure. ZOMACTONshould not be used in patients with evidence of an active malignancy, progressive or recurrent underlying intracranial tumor, active proliferative or severe nonproliferative diabetic retinopathy, or closed epiphysis. As with all therapeutic proteins, there is potential for immunogenicity.

When somatropin is administered subcutaneously at the same site over a long period of time, tissue atrophy may result. This can be avoided by rotating the injection site.

Because somatropin increases growth rate, patients with a history of scoliosis who are treated with somatropin should be monitored for progression of scoliosis.

Somatropin may alter the clearance of drugs metabolized by the CP450 enzyme system and careful monitoring is advisable.

ZOMACTONshould not be used by patients who have had an allergy to growth hormones (somatropin) or any of the other ingredients in ZOMACTON. Benzyl alcohol associated with toxicity in newborns is contained in the diluent supplied with 5mg ZOMACTON.

When administering ZOMACTON5 mg to newborns, it should be reconstituted with sterile normal saline. Practitioners should consider the combined daily metabolic load of benzyl alcohol from all sources. The ZOMACTON10 mg vial is reconstituted with bacteriostatic water for injection containing metacresol and should not be used by patients who are allergic to it. Treatment of patients with coexisting ACTH deficiency should have glucocorticoid replacement dose adjusted to avoid inhibition of growth.

The following adverse reactions have been observed during appropriate use of somatropin: headaches (children and adults), gynecomastia (children), and pancreatitis (children and adults). In studies of growth hormone-deficient children, injection-site reactions (e.g., pain, bruise) occurred in 8 of the 164 treated patients. Leukemia and new-onset Type 2 diabetes mellitus have been reported.
