BURLINGTON, Mass., May 07, 2020 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today reported financial results and recent business highlights for the quarter ended March 31, 2020.

“We were very pleased with ZILRETTA’s trajectory earlier in the first quarter of 2020; however, in March we began to experience impacts from the COVID-19 pandemic,” said Michael Clayman, M.D., President and Chief Executive Officer of Flexion Therapeutics. “The pandemic negatively affected our customers’ ability to treat patients as well as our first-quarter sales, and we believe that COVID-19 will adversely impact revenue for the remainder of the year. That said, our field teams have been utilizing various technologies to engage in conversations with prescribing physicians, and our confidence in ZILRETTA’s long-term potential is undiminished. In fact, given the cancellations and postponements of total knee replacement surgeries, we believe ZILRETTA has the potential to play an increasingly prominent role in a post-pandemic environment. However, since that time horizon is uncertain, we have taken meaningful actions to reduce our operating expenses.”

Dr. Clayman added, “We recently made the strategic decision to discontinue our Phase 2 trial investigating ZILRETTA in shoulder OA and adhesive capsulitis. Given the small number of patients enrolled in that trial, the uncertainty around when we will be able to restart it, as well as the costs required to maintain the study in an inactive status, we believe terminating the trial is the most responsible action at this time. Moving forward, we will look to leverage our learnings from the study and potentially incorporate them into a new trial design to advance ZILRETTA in these indications. We continue to plan to reinitiate the FX201 single ascending dose trial as soon as feasible. Ultimately, we are committed to ensuring Flexion emerges from the crisis in a position of strength and that we are ready to quickly reaccelerate our commercial and R&D activities.”

First-Quarter Results & Financial Highlights
The Company reported a net loss of $36.8 million for the first quarter of 2020, compared to a net loss of $41.5 million for the same period of 2019. Net sales of ZILRETTA were $20.1 million and $10.6 million for the three months ended March 31, 2020 and 2019, respectively. Cost of sales was $2.3 million and $1.8 million for the three months ended March 31, 2020 and 2019, respectively.

Research and development expenses were $21.1 million and $15.4 million for the three months ended March 31, 2020 and 2019, respectively. The increase in research and development expenses of $5.7 million was primarily due to an increase of $2.2 million in salary and other employee-related costs for additional headcount and stock compensation expense, an increase in expenses related to FX201, including the payment of $2.5 million to GeneQuine for dosing the first human patient in the Phase I clinical trial, and an increase in other portfolio expenses, primarily related to the $0.5 million milestone to Xenon Pharmaceuticals, offset by a decrease of $0.5 million in development expenses for ZILRETTA due to lower clinical trial expenses during the period.

Selling, general and administrative expenses were $29.3 million and $32.2 million for the three months ended March 31, 2020 and 2019, respectively. Selling expenses were $20.5 million and $23.8 million for the three months ended March 31, 2020 and 2019, respectively. The year-over-year decrease in selling expenses of $3.3 million was primarily due to a reduction in physician and patient marketing activities. General and administrative expenses were $8.8 million and $8.4 million for the three months ended March 31, 2020 and 2019, respectively, which represents an increase of $0.4 million.

Interest income was $0.4 million and $1.0 million for the three months ended March 31, 2020 and 2019, respectively. Interest expense was $4.7 and $3.9 million for the three months ended March 31, 2020 and 2019, respectively.

As of March 31, 2020, the Company had approximately $125.2 million in cash, cash equivalents and marketable securities compared with $136.7 million as of December 31, 2019.

ZILRETTA Commercial Metrics
Since the launch of ZILRETTA in November 2017 through March 31, 2020:

• 3,672 of our approximately 5,000 target accounts had purchased ZILRETTA. This reflects growth of 184 accounts over the period from launch through December 31, 2019 when 3,488 accounts had purchased product.
• 77% of purchasing accounts (2,832) had placed at least one reorder.
• 916 accounts had made ZILRETTA purchases of more than 50 units; 1,077 accounts had purchased 11 to 50 units; and 1,679 accounts had purchased between 1 and 10 units.
• Accounts that had purchased more than 50 ZILRETTA units accounted for 177,664 of the total 212,327 ZILRETTA units purchased.

Reductions in Operating Expenses
In response to the economic and business disruption caused by COVID-19, Flexion undertook prudent and disciplined steps to reduce expenses across the organization. The Company believes these steps will enhance financial flexibility and liquidity and estimates they will deliver between $43 million and $53 million in savings this year. As a result, Flexion expects full-year 2020 operating expenses (including cost of sales, research and development, and selling, general and administrative) will be in the range of $167 million to $177 million. The Company expects to achieve these cost savings through:

• Hiring and travel freezes;
• Suspension and/or termination of active clinical trials;
• Elimination of live presence at medical and industry conferences, reductions in in-person physician speaker programs and reductions in market research and select marketing programs and materials; and
• Elimination of non-essential operating expenses.

ZILRETTA Supply Chain
The Company remains confident in its ability to maintain adequate commercial supply of ZILRETTA and expects its current finished goods inventory will be sufficient to meet demand for at least the remainder of 2020. To avoid excess levels of inventory, Flexion is temporarily suspending manufacturing activities for ZILRETTA. Since Flexion employs a “condominium model” at Patheon’s manufacturing site, the Company has the ability to reinitiate manufacturing following three months’ notice to Patheon once additional supply is needed.

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 knee pain for 12 weeks, with some people experiencing pain relief through Week 16.

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 2018, more than 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.

About FX201
FX201 is a locally administered gene therapy product candidate which utilizes a helper-dependent adenovirus (HDAd) vector, designed to stimulate the production of an anti-inflammatory protein, interleukin-1 receptor antagonist (IL-1Ra), whenever inflammation is present within the joint. Inflammation is a known cause of pain, and chronic inflammation is thought to play a major role in the progression of osteoarthritis (OA). By persistently suppressing inflammation, Flexion believes FX201 holds the potential to both reduce OA pain and modify disease progression.

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.
