EWING, N.J., Nov. 03, 2015 (GLOBE NEWSWIRE) -- Antares Pharma, Inc. (NASDAQ:ATRS) today announced that enrollment has been completed in a dose-blinded, multiple-dose, concentration controlled 26-week safety and pharmacokinetic study of QuickShot ® Testosterone (QS T) administered subcutaneously once each week to adult males with hypogonadism.   The study, QST-15-005 includes a screening phase, a titration phase and a treatment phase for evaluation of safety and tolerability assessments, including laboratory assessments, adverse events and injection site assessments.  The study is being conducted to help ensure that we satisfy the U.S. Food and Drug Administration's recommendation that we have a safety database of approximately 350 subjects exposed to QS T in total with approximately 200 subjects exposed for six months and approximately 100 subjects exposed for a year. 

"We are very pleased with the high interest and rapid enrollment of this supplemental safety study," stated Eamonn P. Hobbs, President and Chief Executive Officer. "Given the previously disclosed positive efficacy results from the QST-13-003 study, we remain very excited about the potential for this product, and we will work closely with the Food and Drug Administration toward a potential approval."

In this study, patients meeting all eligibility criteria are assigned to receive 75 mg of QS T once weekly for six weeks.  According to the protocol, adjustments to dose may be made at week seven based upon the week six C trough value.  QS T will be provided to clinical sites at dosage strengths of 100 mg, 75 mg and 50 mg to be utilized in dose titration.  Currently, 119 patients in this study have received a dose of QS T.  Following completion of screening, we estimate the total number of dosed patients will be approximately 125.  We anticipate the last patient in the study will complete their final visit by the end of the second quarter 2016.
