Flexion Therapeutics Reports Second-Quarter 2020 Financial Results and Recent Business Highlights

• Company reported ZILRETTA® (triamcinolone acetonide extended-release injectable suspension) net sales of $15.5 million in second quarter 2020
  
• Flexion resumed enrollment in Phase 1 dose-escalation trial for FX201; FX301 on track to enter clinic in 2021

BURLINGTON, Mass., Aug. 05, 2020 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today reported financial results and recent business highlights for the quarter ended June 30, 2020.

“In light of the significant challenges presented by COVID-19, we made excellent progress across all areas of the business in the second quarter,” said Michael Clayman, M.D., President and Chief Executive Officer of Flexion Therapeutics. “We saw demand for ZILRETTA build month-over-month throughout the quarter, and we continued to add new accounts, bolstering our confidence that ZILRETTA can become the leading intra-articular therapy for OA knee pain. Furthermore, in May, following the voluntary suspension of clinical trials, we resumed the Phase 1, dose-escalation trial evaluating the safety and tolerability of FX201, our novel, intra-articular, IL-1RA gene therapy product candidate in development for the treatment of OA. In addition, we continued to advance the preclinical program for FX301, a locally administered peripheral nerve block product candidate for control of post-operative pain, and we remain on track to enter the clinic in 2021. While the impacts of the pandemic on the second half of the year are impossible to predict, our confidence in ZILRETTA and our ability to advance our pipeline of compelling product candidates, remains as strong as ever.”

Second-Quarter Results & Financial Highlights

The Company reported a net loss of $32.6 million for the second quarter of 2020, compared to a net loss of $36.5 million for the same period of 2019. Net sales of ZILRETTA were $15.5 million and $17.0 million for the three months ended June 30, 2020 and 2019, respectively.

Flexion recognizes revenue primarily on sales of ZILRETTA to specialty distributors and a specialty pharmacy versus the purchases of ZILRETTA by healthcare providers. Due to the impacts of COVID-19, the level of product inventory held at specialty distributors at the end of the first quarter was higher than prior quarters. As purchases of ZILRETTA by healthcare providers increased throughout the second quarter, the specialty distributors worked through their elevated inventory levels. As a result, the aggregate number of ZILRETTA units that specialty distributors purchased and that the Company recognized as revenue in the second quarter was less than the aggregate amount purchased by healthcare providers from specialty distributors during this period.

Cost of sales was $5.5 million and $1.4 million for the three months ended June 30, 2020 and 2019, respectively. For the three months ended June 30, 2020, cost of sales included $1.6 million for the actual cost of units sold, $3.4 million of unabsorbed overhead associated with the voluntary, temporary suspension of manufacturing activities at Patheon due to COVID-19 impacts on sales of ZILRETTA, and $0.5 million of period costs and other adjustments.

Research and development expenses were $12.5 million and $16.1 million for the three months ended June 30, 2020 and 2019, respectively. The decrease in research and development expenses of $3.6 million was primarily due to a decrease of $2.7 million in development expenses for ZILRETTA due to lower ZILRETTA clinical trial activity during the period, as well as a decrease of $1.0 million in salary and other employee-related costs and stock-based compensation expense related to lower headcount.

Selling, general and administrative expenses were $24.7 million and $33.1 million for the three months ended June 30, 2020 and 2019, respectively. Selling expenses were $16.8 million and $24.8 million for the three months ended June 30, 2020 and 2019, respectively. The year-over-year decrease of $8.0 million was primarily due to the expense reduction measures taken in response to COVID-19. General and administrative expenses were $7.9 million and $8.3 million for the three months ended June 30, 2020 and 2019, respectively, which represents a decrease of $0.4 million.

As a result of the Company’s musculoskeletal business managers (MBMs) returning to the field and the resumption of the clinical trial for FX201, Flexion expects full-year 2020 total operating expenses (including cost of sales, research and development, and selling, general and administrative) will be in the range of $172 million to $182 million versus previous guidance of $167 million to $177 million.

Interest income was $0.1 million and $0.8 million for the three months ended June 30, 2020 and 2019, respectively. Interest expense was $5.0 and $3.9 million for the three months ended June 30, 2020 and 2019, respectively.

As of June 30, 2020, the Company had approximately $200.6 million in cash, cash equivalents and marketable securities compared with $136.7 million as of December 31, 2019. Based on the Company’s current operating plan and assuming purchasing activity at physician practices, clinics and certain medical centers or hospitals that administer ZILRETTA begin to return to pre-COVID-19 levels by early 2021, Flexion believes that its current cash, cash equivalent and marketable securities, will be sufficient to fund operations into 2022.

About ZILRETTA
On October 6, 2017, ZILRETTA was approved by the U.S. FDA as the first and only extended-release intra-articular therapy for patients confronting osteoarthritis-related knee pain. ZILRETTA employs proprietary microsphere technology combining triamcinolone acetonide — a commonly administered, short-acting corticosteroid — with a poly lactic-co-glycolic acid (PLGA) matrix to provide extended pain relief. The pivotal Phase 3 trial on which the approval of ZILRETTA was based showed that ZILRETTA significantly reduced OA knee pain for 12 weeks, with some people experiencing pain relief through Week 16.

About FX201
FX201 (humantakinogene hadenovec) is a novel, intra-articular gene therapy product candidate which utilizes a helper-dependent adenovirus [HDAd] vector based on human serotype 5 (Ad5) that is designed to transfer a gene to cells in the joint to produce an anti-inflammatory protein, interleukin-1 receptor antagonist (IL-1Ra), under the control of an inflammation-sensitive promoter. Inflammation is a known cause of pain, and chronic inflammation is thought to play a major role in the progression of OA. By persistently suppressing inflammation, Flexion believes FX201 holds the potential to provide long-term pain relief and functional improvement, and to modify the disease.

About FX301
FX301 is a locally administered NaV1.7 inhibitor product candidate, known as funapide formulated for extended release in a thermosensitive hydrogel. The initial development of FX301 is intended to support administration as a peripheral nerve block for control of post-operative pain. Flexion believes FX301 has the potential to provide effective and durable pain relief while preserving motor function and anticipates initiating clinical trials in 2021.

About Osteoarthritis (OA) of the Knee
OA, also known as degenerative joint disease, affects more than 30 million Americans and accounts for more than $185 billion in annual expenditures. In 2017, approximately 15 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. The prevalence of OA is expected to continue to increase as a result of aging, obesity and sports injuries. Each year, approximately five million OA patients receive either a corticosteroid (immediate-release or extended-release) or hyaluronic acid intra-articular injection to manage their knee pain.
