EWING, N.J., Dec. 21, 2016 (GLOBE NEWSWIRE) -- Antares Pharma, Inc. (NASDAQ:ATRS) today announced that it had submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for QuickShot® Testosterone (QST), a drug-device combination product for the delivery of testosterone enanthate using a subcutaneous auto injector.  QST is intended to treat adult men with low testosterone associated with a condition known as hypogonadism. 

“The submission of the QST New Drug Application represents yet another significant accomplishment for the Company in 2016.  It is the first product designed for subcutaneous delivery of testosterone through a fine gauge needle in patients diagnosed with hypogonadism,” said Robert F. Apple, President and Chief Executive Officer.  “We believe QST could be an excellent treatment option for men with hypogonadism.  In addition to virtually eliminating the risk of transference that exists with topical gel products and the uncomfortable deep intramuscular administration associated with current injectable therapies, the study data demonstrated that the QuickShot auto injector can provide patients with physiologically normal and steady levels of testosterone over the course of therapy. A potential added benefit to patients is a virtually painless treatment experience as demonstrated by the pain data collected in our phase 3 program. We will work closely with the FDA during the regulatory review process towards a potential approval with the goal of bringing this new treatment option to men diagnosed with hypogonadism.”

Two hundred and eighty-three men participated in the QST phase 3 program.  The phase 3 program consisted of a one year pivotal safety and efficacy study and a second 6-month safety study.  In the phase 3 program, patients received 75 mg of testosterone enanthate (TE) administered via the QuickShot® device once-weekly for 6 weeks. At week 7, blinded dose adjustments were made if necessary based on week 6 pre-dose blood levels.  The patients continued to receive subcutaneous doses of 50 mg, 75 mg or 100 mg of testosterone weekly for up to 52 weeks.  The QuickShot® testosterone auto injector has not been approved by the United States Food and Drug Administration.

About QuickShot® Testosterone

The investigational subcutaneous testosterone enanthate auto injector is a proprietary, self-administered testosterone replacement option for men diagnosed with hypogonadism that is designed to be injected at home, on a weekly basis. Results from the previously reported Phase 3 pharmacokinetic study showed that testosterone delivered subcutaneously using the QuickShot® testosterone auto injector provided rapid, steady, and reliable efficacy by restoring testosterone to pre-defined physiologic levels.

About QuickShot® Auto Injector

The proprietary QuickShot® auto injector is designed to allow rapid subcutaneous self-administration of highly viscous drugs such as testosterone and biologics using high spring pressure through a fine gauge needle.  Conventional auto injectors, or even a vial, needle and syringe could not inject these drugs efficiently or as fast and easy as the QuickShot® device.  The QuickShot® auto injector can also provide the patient with the ease and speed of self-administration, comfort and discretion.

About Hypogonadism

Hypogonadism, also known as testosterone deficiency or Low T, is a condition in which the body does not produce enough testosterone – the hormone that plays a key role in masculine growth and development during puberty, and maintenance of musculoskeletal, metabolic, and mental health in maturity.  Symptoms of male hypogonadism can be treated with testosterone replacement therapy.
