BURLINGTON, Mass., Aug. 08, 2017 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today reported financial results for the quarter ended June 30, 2017. The company reported a net loss of $28.9 million for the second quarter of 2017, compared to a net loss of $14.2 million for the same period of 2016.

Research and development costs increased to $11.8 million in the second quarter of 2017, as compared to $8.9 million in the second quarter of 2016, due primarily to an increase of $3.0 million in personnel and other employee-related costs for additional headcount and stock compensation expense. General and administrative expenses increased to $15.1 million in the first quarter of 2017, as compared to $5.2 million for the same period in 2016, due primarily to costs associated with increased headcount and expenses related to the potential launch and commercialization of Zilretta (FX006), Flexion’s lead investigational program for pain associated with osteoarthritis (OA) of the knee.

As of June 30, 2017, the company had approximately $359.9 million in cash, cash equivalents and marketable securities compared with $210.3 million as of December 31, 2016.

Recent News and Highlights:

• On May 2, 2017, Flexion completed an offering of convertible senior notes due in 2024, providing a capital infusion of approximately $201 million (gross proceeds) and extending the company’s cash runway well into 2019.
   
• The company has fully staffed its sales leadership team and is actively recruiting approximately 100 field sales representatives who will be hired on a contingent basis conditional upon Zilretta’s approval by the U.S. Food and Drug Administration (FDA). Pending regulatory approval, the company expects to launch Zilretta in the fourth quarter of 2017.
   
• A Phase 3 clinical trial to evaluate the safety of repeat administration of Zilretta has been fully enrolled.  Study participants will be followed for 52 weeks, and the final data readout is expected in the second half of 2018.
  
  
• The full data set from a Phase 2 clinical trial of Zilretta in patients with Type 2 diabetes and OA of the knee was presented at the American Diabetes Association's 77th Scientific Sessions. The data demonstrated that Zilretta was not associated with the significant rise in blood glucose seen with an immediate-release steroid in patients with Type 2 diabetes and OA of the knee.
   
• A health economics analysis of Zilretta was presented at the International Society for Pharmacoeconomics and Outcomes Research 22^nd International Meeting. The study, which utilized established health economic metrics, demonstrated that Zilretta has the potential to be a cost-effective therapy in OA of the knee.
   
• Company executives provided updates on commercialization plans and two clinicians shared their medical perspectives on Zilretta during an Investor and Analyst Day held on July 10, 2017. Management announced plans to initiate clinical trials of Zilretta in OA of the hip and shoulder by year-end.
   
• During the Investor and Analyst Day presentation, the company unveiled a new pre-clinical pipeline candidate, FX101 (fluticasone extended-release), for the potential treatment of OA pain in large joints. The program is expected to follow the 505(b)(2) pathway. Based on robust pre-clinical pharmacokinetic data, the company believes FX101 has the potential to provide pain relief for up to six months.
   
• Flexion’s executive team was strengthened by the recent appointment of Mark Levine as General Counsel and Corporate Secretary. Additionally, the company has named Anna Diaz Triola as Vice President, Marketing. Ms. Triola brings nearly 20 years of marketing experience in biotechnology companies and deep commercial expertise in new product launches, new product planning, and patient advocacy and engagement across a variety of disease areas.

“Flexion’s strong momentum continued to build throughout the second quarter,” said Michael Clayman, M.D., President and Chief Executive Officer.  “Our commercial organization made impressive strides preparing for the potential launch of Zilretta, and we are eagerly anticipating our Prescription Drug User Fee Act (PDUFA) action date of October 6, 2017.”

Dr. Clayman added, “The full enrollment of the repeat administration study of Zilretta represents a major milestone, and we look forward to our planned initiation of new clinical trials in OA of the hip and shoulder by year-end. We are also very pleased to introduce FX101, an important addition to our pipeline, which we believe has the potential to make a meaningful difference for patients confronting OA pain.”

About Osteoarthritis (OA) of the Knee
OA is the most common joint disease, affecting more than 30 million Americans and accounting for more than $185 billion in annual expenditures. In 2015, more than 14 million Americans were diagnosed with OA of the knee and the average age of physician-diagnosed knee OA has fallen by 16 years, from 72 in the 1990s to 56 in the 2010s. OA prevalence is expected to continue to increase as a result of aging, obesity and sports injuries. Each year, more than five million OA patients in the U.S. receive either an immediate-release corticosteroid or hyaluronic acid intra-articular injection for knee pain.

About Zilretta
Zilretta is being investigated as the first intra-articular, extended-release treatment for patients with OA related knee pain. Zilretta employs proprietary microsphere technology combining triamcinolone acetonide — a commonly administered, short-acting corticosteroid — with a poly lactic-co-glycolic acid matrix. In February 2017, the FDA accepted the company's New Drug Application for Zilretta in OA of the knee. Under the Prescription Drug User Fee Act, the agency has established a user fee goal date of October 6, 2017.
