EWING, N.J., April 03, 2017 (GLOBE NEWSWIRE) -- Antares Pharma, Inc. (NASDAQ: ATRS ) today announced that data from the 52-week pharmacokinetics and safety phase 3 study of subcutaneous testosterone enanthate delivered through the QuickShot ® auto injector was selected for a moderated poster presentation at the Endocrine Society Annual Meeting (ENDO 2017). The poster will be presented today, April 3, 2017.
The poster, entitled “Safety, Efficacy, and Metabolic Parameters in the STEADY ™ Trial of a Novel, Pre-Filled Subcutaneous Testosterone Enanthate Auto-Injector (SCTE-AI),” was authored by Christina Wang, MD, co-principle investigator for the study at Los Angeles Biomedical Research Institute and Harbor-UCLA Medical Center, Los Angeles, CA, et al. The submission was among a select group of key abstracts awarded the distinction of a moderated poster presentation.
The dose-blind, multicenter Subcutaneous Testosterone Efficacy and Safety in Adult Men Diagnosed with Hypogonadism (STEADY™) trial of a proprietary, pre-filled auto injector enrolled 150 hypogonadal adult men with baseline testosterone (T) levels of <300 ng/dL. Patients received 75 mg of testosterone enanthate administered via auto injector once-weekly for six weeks. At week seven blinded dose adjustments were based upon the week six blood concentration levels at end of the dosing interval (C trough ) in the patients. The primary endpoint was the percentage of patients achieving a C avg of 300 to 1,100 ng/dL and a key secondary endpoint was percentage of patients with week 12 C max testosterone values of <1500 ng/dL. Markers of glucose metabolism (M) and insulin resistance risk (IR) were assessed via the Quantose™ insulin resistance (IR) panel. Quantose™ IR and M scores and cholesterol panel assessments were performed from blood samples at weeks 1, 13, 26, 38 and 52.
Of the 150 patients enrolled, 139 patients met the primary endpoint at week 12. Overall, the study found that QuickShot ® testosterone (QST) administered to hypogonadal men achieved serum testosterone levels within a clinically desirable and physiologically normal range. Quantose™ IR and M scores suggested a large portion of the patient population exhibited a prediabetic/diabetic phenotype at baseline, and insulin resistance scores were decreased from baseline throughout the treatment period. Total cholesterol, triglycerides, LDL and HDL levels decreased with treatment. According to the investigators, QST was found to be safe, well tolerated and virtually pain free.
“We are pleased that data from our phase 3 QuickShot testosterone study has been accepted for presentation at the annual ENDO 2017 meeting,” said Robert F. Apple, CEO of Antares Pharma. Mr. Apple continued, “We believe data compiled to date from our QST clinical program have shown that adult men diagnosed with hypogonadism can achieve a steady pharmacokinetic profile for testosterone well within the physiologically normal range over the course of therapy. We also believe QST has been shown to be well tolerated and virtually painless. We will continue to work closely with the FDA during the regulatory review process toward a potential approval.”

About The Endocrine Society The 100-year-old Endocrine Society is the largest global membership organization representing professionals from the intriguing field of endocrinology. Medical doctors, scientists, researchers, and educators comprise the majority of the Society’s membership. Endocrinologists conduct research on – and treat patients with – a host of conditions and diseases related to the human body’s complex system of glands and hormones. Hormonal disruptions cause conditions that affect millions of people, including diabetes, thyroid disorders, obesity, infertility, growth disorders, sleep disorders, and endocrine cancers. Endocrine Society members come from 122 countries, with 40 percent of them located outside the United States.
About QuickShot ® Testosterone The investigational subcutaneous testosterone enanthate auto injector is a proprietary self-administered testosterone replacement option for men 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 restoration of testosterone to pre-defined physiologic levels.
The most common adverse reactions (incidence ≥5%) in the phase 3 study referenced in these presentations were increased hematocrit, hypertension, increased PsA, Upper Respiratory Tract Infection, sinusitis, injection site bruising and headache. Serious adverse events reported included one case each of worsening depression, vertigo and suicide. All of the SAE’s were not considered to be related to study drug by the investigators, however the Company determined that the case of suicide could not be ruled out as potentially being related to study drug. There have been no reported adverse events consistent with urticaria (hives), POME, anaphylaxis or major adverse cardiovascular events in this study. The safety data collected included an assessment of pain. When pain was reported its intensity was recorded using a 10-point pain scale, with a score of 1 described as barely noticeable and 10 as the worst pain experienced. Of 1519 injections assessed, pain was reported 9 times. In these 9 instances, the pain intensity was reported as either a 1 or a 2, with an average score of 1.3. The QuickShot ® testosterone auto injector has not been approved by the United States Food and Drug Administration.
