Allergan And Paratek Pharma Announce Positive Results From Two Phase III Trials Of Sarecycline For The Treatment Of Moderate To Severe Acne

DUBLIN and BOSTON, March 27, 2017 /PRNewswire/ -- Allergan plc, (NYSE: AGN), a leading global pharmaceutical company and Paratek Pharmaceuticals, Inc. (Nasdaq: PRTK), a biopharmaceutical company focused on the development and commercialization of innovative therapies based upon tetracycline chemistry, announced that two (2) Phase 3 trials of sarecycline for the treatment of moderate to severe acne met their 12 week primary efficacy endpoints. Sarecycline is a once-daily, oral, narrow spectrum tetracycline-derived antibiotic with anti-inflammatory properties for the potential treatment of moderate to severe acne in the community setting. Based on these data, Allergan plans to file a New Drug Application (NDA) to the U.S. Food & Drug Administration (FDA) in the second half of this year.

“The positive efficacy results observed in the pivotal phase 3 clinical trials indicate that sarecycline can be an effective treatment option for patients with moderate to severe acne.” said David Nicholson, Chief Global Research & Development Officer at Allergan. “We look forward to submitting a new drug application for sarecycline and bringing to market a potential new option for physicians treating patients with acne.”

“We are pleased with the results of the sarecycline Phase 3 program and Allergan’s intention to move ahead with an NDA submission for approval in the U.S. by the end of 2017,” said Evan Loh, M.D., President, Chief Operating Officer and Chief Medical Officer, Paratek. “Sarecycline is a narrow spectrum antibiotic, which we believe can offer meaningful clinical benefits for patients afflicted with acne.”

About SC1401 and SC1402
Both SC1401 & SC1402 were designed to be replicative phase 3 randomized, multicenter, double-blind, placebo-controlled studies to evaluate the efficacy and safety of 1.5 mg/kg per day of sarecycline compared to placebo in the treatment of moderate to severe acne.

The primary objective was to evaluate the efficacy and safety of oral sarecycline 1.5 mg/kg per day compared to placebo in treating inflammatory acne lesions in subjects with moderate to severe acne based on Investigators Global Assessment (IGA) scale score and inflammatory lesion counts. Patients were randomized (1:1) into two treatment groups to receive either sarecycline tablets (60 mg, 100 mg and 150 mg, providing a dose of 1.5 mg/kg/day) or placebo once a day for 12 weeks.

Sarecycline was statistically significantly (p < 0.004) superior to placebo with respect to primary efficacy endpoints. The most common adverse events (>2%) reported in the sarecycline group were nausea (3.2%), nasopharyngitis (2.8%), and headache (2.8%). The rate of discontinuation due to adverse events among sarecycline-treated patients in the two studies combined was 1.4%.

About Paratek Pharmaceuticals, Inc.
Paratek Pharmaceuticals, Inc. is a biopharmaceutical company focused on the development and commercialization of innovative therapies based upon its expertise in novel tetracycline chemistry. Paratek’s lead product candidate, omadacycline, is the first in a new class of tetracyclines known as aminomethylcyclines, with broad-spectrum activity against Gram-positive, Gram-negative and atypical bacteria. In June 2016, Paratek announced positive efficacy data in a Phase 3 registration study in acute bacterial skin and skin structure infections (ABSSSI) demonstrating the efficacy and safety of intravenous (IV) to once-daily oral omadacycline compared to linezolid. A Phase 3 registration study for community-acquired bacterial pneumonia (CABP) comparing IV-to-once-daily oral omadacycline to IV-to-oral moxifloxacin was initiated in November 2015 and completed enrollment in January 2017. Paratek will report top-line data from this study early in the second quarter of 2017. A Phase 3 registration study in ABSSSI comparing once-daily oral-only dosing of omadacycline to twice-daily oral-only dosing of linezolid was initiated in August 2016. Top-line data from this study are expected as early as the second quarter of 2017. A Phase 1B study in uncomplicated urinary tract infections (UTI) was initiated in May 2016 and positive top-line PK proof-of-principle data were reported in November 2016. The company plans to begin enrolling patients in a proof-of-concept Phase 2 study in complicated UTI as early as the fourth quarter of 2017. Omadacycline has been granted Qualified Infectious Disease Product designation and Fast Track status by the U.S. Food and Drug Administration for several indications.

In October 2016, Paratek announced a new cooperative research effort with the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) to study omadacycline against pathogenic agents causing infectious diseases of public health and biodefense importance. These studies are designed to confirm dosing regimens and assess efficacy of omadacycline against biodefense pathogens, including Yersinia pestis (plague) and Bacillus anthracis (anthrax).

Omadacycline is a new once-daily oral and IV, well-tolerated broad spectrum antibiotic being developed for use as empiric monotherapy for patients suffering from serious community-acquired bacterial infections, such as acute bacterial skin and skin structure infections, community-acquired bacterial pneumonia, urinary tract infections and other community-acquired bacterial infections, particularly when antibiotic resistance is of concern to prescribing physicians.

Paratek’s second Phase 3 product candidate, sarecycline, is a well-tolerated, once-daily, oral, narrow spectrum tetracycline-derived antibiotic with potent anti-inflammatory properties for the potential treatment of acne and rosacea in the community setting. Allergan owns the U.S. rights for the development and commercialization of sarecycline. Paratek retains all ex-U.S. rights. For more information, visit www.paratekpharma.com.
