Flexion Therapeutics Reports First-Quarter 2015 Financial Results

Key Highlights

• Announced a U.S. Department of Defense (DoD) grant worth approximately $2 million to conduct a Phase 2 clinical trial to study lead compound FX006 in active military and medically retired veterans with post-traumatic osteoarthritis (OA)
• Advanced FX006 by initiating Phase 3 clinical trial on schedule and completing enrollment in pivotal Phase 2b clinical trial
• Appointed Scott Canute, former President of Global Manufacturing at Eli Lilly and Company and subsequently at Genzyme Corporation, as new Board member

BURLINGTON, Mass., May 7, 2015 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today announced financial results for the first quarter ended March 31, 2015.

"The team at Flexion was clearly productive during the first quarter of 2015, as we initiated our international Phase 3 clinical trial for FX006 (an intra-articular, sustained release steroid for the treatment of patients with OA knee pain), and completed enrollment in our first pivotal trial (Phase 2b) for the compound. In addition, we also strengthened our Board of Directors during Q1 with the addition of seasoned pharmaceutical manufacturing executive Scott Canute," said Michael Clayman, M.D., Flexion Therapeutics President and Chief Executive Officer.

"As the year continues, we anticipate announcing data from the first pivotal trial and completing enrollment in our Phase 3 trial, both in Q4. We expect that positive data from these pivotal trials will enable us to submit a New Drug Application (NDA) to the U.S. Food & Drug Administration (FDA) for FX006 in 2016," added Dr. Clayman.

First-Quarter Financial Results

The company reported a net loss of $9.2 million for the first quarter of 2015, compared to a net loss of $6.5 million for the first quarter of 2014.

Research and development expenses increased to $6.3 million in the first quarter of 2015, compared to $4.2 million for the same period in 2014, due to an increase in FX006 program expenses related to the pivotal Phase 2b and Phase 3 clinical trials and higher expenses related to manufacturing.

General and administrative expenses increased to $2.8 million in the first quarter of 2015, as compared to $2.3 million for the same period in 2014, due primarily to increases in salary and related costs associated with increased headcount including stock based compensation expense.

As of March 31, 2015, the company had $137.4 million in cash, cash equivalents, and marketable securities compared to $151.6 million as of December 31, 2014.

First Quarter Highlights and Recent News:

• In April 2015, we announced that the DoD awarded the company a grant worth approximately $2 million and that we have initiated a Phase 2 clinical trial investigating FX006 as treatment for OA pain in active military and medically retired veterans with post-traumatic OA of the knee.
   
• In February 2015, we initiated a randomized, double-blind, Phase 3 clinical trial of FX006 that will take place at about 50 centers worldwide. Approximately 450 patients will be randomized to one of three treatment groups (1:1:1) and treated with a single IA injection of either saline (placebo) or 40 mg of FX006 or 40 mg of triamcinolone acetonide (TCA). The primary endpoint of this study is the magnitude of pain relief of FX006 at 12 weeks versus placebo and patients will be evaluated through week 24. Secondary objectives of this study include assessing the effect of FX006 on the magnitude and duration of pain relief relative to TCA. The current pivotal Phase 2b trial and the newly initiated Phase 3 trial are designed to provide the required data for FX006 to be submitted for regulatory approval by the FDA.
   
• Also in February 2015, we completed enrollment in a pivotal Phase 2b multi-center, randomized, double-blind, placebo-controlled study in 310 patients with OA of the knee. Results, which we expect to release later this year, will address the safety, tolerability and efficacy of FX006. Like the Phase 3 trial, the primary endpoint of the trial is the magnitude of pain relief of FX006 40 mg at 12 weeks versus placebo and patients will continue to be evaluated through week 24.
   
• We further strengthened our Board of Directors in March 2015 with the appointment of Scott Canute, the former President of Global Manufacturing Operations at Eli Lilly and Company and subsequently the President of Global Manufacturing and Corporate Operations at Genzyme Corporation.
