PRINCETON, N.J., Feb. 11, 2019 (GLOBE NEWSWIRE) -- Agile Therapeutics, Inc., (Nasdaq: AGRX), a women’s healthcare company, today announced topline results from a comparative wear study testing the adhesion of Twirla® compared to that of Xulane® (the “comparative wear study”), the generic version of the previously marketed Ortho Evra® contraceptive patch, a product the U.S. Food and Drug Administration (“FDA”) considers to have acceptable adhesion.  In the study, Twirla met its primary endpoint and demonstrated non-inferior adhesion to Xulane.

The Company conducted the comparative wear study as part of its plan to implement the recommendations of the FDA’s Office of New Drugs (“OND”) that were delivered to the Company in OND’s formal dispute resolution decision letter.  OND recommended that the Company complete a comparative wear study as part of a potential path forward for seeking regulatory approval of the Twirla NDA.

The comparative wear study design follows the 2018 ANDA Guidance for Assessment of Adhesion entitled Assessing Adhesion With Transdermal and Topical Delivery Systems for ANDAs. The study was a randomized, open-label, crossover adhesion study in healthy women aged 18 to 35 years with a Body Mass Index of less than 35 kg/m2. Subjects were randomized to wear either Twirla or Xulane for the first week and then switched to the patch not initially worn for the second week.  Eighty-three subjects were randomized; 79 subjects completed the study, and 77 subjects were included in the Per Protocol population used in the primary analysis.  Investigators assessed patch adhesion for each day of wear and assigned the patch a daily score ranging from 0 (essentially no patch lift off skin) to 4 (complete patch detachment).

The primary endpoint for the study was the mean difference in adhesion scores between Twirla and Xulane.  As agreed upon at the December 2018 Type A meeting with the FDA’s Division of Bone, Reproductive, and Urologic Products (“DBRUP”), Twirla was to be considered statistically non-inferior to Xulane if the upper 95% confidence limit of the mean difference was less than +0.15.  The study met this non-inferiority criterion by demonstrating a mean difference of -0.25 and upper 95% confidence limit of -0.16.  (See Table 1).

Table 1 shows the results for the primary endpoint: the mean difference in adhesion scores between Twirla and Xulane. The mean difference in Twirla minus Xulane is -0.25. The mean adhesion score for Xulane is higher than the mean score for Twirla, producing a negative mean difference. The upper bound of the 95% confidence limit for the mean difference is -0.16, thus Twirla met the non-inferiority criterion of +0.15. (See Figure 1).

No complete detachments of Twirla or Xulane occurred during the trial.  The final study report, when complete, will contain additional analyses pertaining to secondary endpoints and safety data.

“We believe that the topline data from our comparative wear study provide important insights into the adhesion performance of Twirla that we can share with the FDA to support that Twirla demonstrates adequate in vivo adhesion.  While the results from the study will need to be reviewed by the FDA as part of our planned NDA resubmission, we are very pleased with the results,” said Dr. Elizabeth Garner, Senior Vice-President and Chief Medical Officer of Agile.  “We greatly appreciate the hard work and dedication from our clinical team and wish to thank the research professionals and staff at TKL Research, and most importantly, the women who participated in the trial.”

The Company plans to include the results of the comparative wear study along with additional information relating to the manufacture of Twirla in its response to the Complete Response Letter (“CRL”) it received in December 2017.  The FDA has previously informed the Company that in connection with its review of the Twirla NDA, the FDA plans to bring the safety and efficacy of Twirla to an Advisory Committee.  The Company also expects that the FDA will conduct a pre-approval inspection of the Company’s third-party manufacturer’s facility, which must be successfully completed prior to approval.

“We believe that the topline results from the comparative wear study enable us to respond to the in vivo adhesion questions raised by the FDA in the December 2017 CRL and in subsequent communications,” said Al Altomari, Chairman and Chief Executive Office of Agile.  Mr. Altomari continued, “We are now focused on completing our plan to resubmit our Twirla NDA in the first half of 2019, which we believe will position us to receive a PDUFA date before the end of the year.”

About Twirla® (AG200-15)
Twirla (levonorgestrel/ethinyl estradiol transdermal system) or AG200-15 is an investigational low-dose, once-weekly contraceptive patch. AG200-15 is a combined hormonal contraceptive (“CHC”) patch that contains the active ingredients ethinyl estradiol (EE), a type of estrogen and levonorgestrel (“LNG”), a type of progestin. Twirla is designed to be applied once weekly for three weeks, followed by a week without a patch.  The Company has completed its Phase 3 clinical trials of Twirla and is pursuing regulatory approval in the U.S.  Agile received a complete response letter (“CRL”) from the FDA in December 2017 relating to the New Drug Application (“NDA”) for Twirla.  In the CRL, the FDA informed the Company that the product could not be approved in its present form due to deficiencies related to, among other things, the in vivo adhesion properties of Twirla and their potential relationship to the Company’s Phase 3 clinical trial results.  With the successful completion of the comparative wear study, the Company plans to resubmit the Twirla NDA in the first half of 2019.
