BURLINGTON, Mass., Aug. 04, 2021 (GLOBE NEWSWIRE) -- Flexion Therapeutics, Inc. (Nasdaq:FLXN) today reported financial results and recent business highlights for the quarter ended June30, 2021.

We are encouraged by the growth of ZILRETTA sales in the second quarter of 2021, and today we are reiterating our full-year net sales guidance in the range of $120million to $130million, said Michael Clayman, M.D., President and Chief Executive Officer of Flexion Therapeutics. While the successful commercialization of ZILRETTA is and will remain our highest priority, we continue to make excellent progress with our innovative pipeline programs. We have fully enrolled the single ascending dose (SAD) portion of our Phase1b study investigating FX301 in post-operative pain following bunionectomy, and we have also fully enrolled the initial part of the FX201 Phase1 SAD trial. We remain on track to share data updates on FX301 and FX201 by the end of the year.

Dr. Clayman added, The refinanced term loan is an important source of non-dilutive capital that, combined with our ongoing cost-containment efforts and anticipated ZILRETTA sales growth, strengthens our balance sheet and extends our estimated cash runway into 2023.

Second-Quarter Results & Financial Highlights

The Company reported a net loss of $22.2million for the second quarter of 2021, compared to a net loss of $32.6million for the same period of 2020. Net sales of ZILRETTA were $28.2million and $15.5million for the three months ended June30, 2021 and 2020, respectively. Cost of sales was $5.0million and $5.5million for the three months ended June30, 2021 and 2020, respectively. Loss per share for the second quarter of 2021 was $0.44, compared to $0.76 for the same period of 2020.

Research and development expenses were $12.7million and $12.5million for the three months ended June30, 2021 and 2020, respectively. The net result reflects a decrease of $0.9million in development expenses due to a reduction in ZILRETTA life cycle management activities and a decrease of $0.5million in salary and other employee-related costs and stock-based compensation expense related to lower headcount. The decreases were partially offset by increases of $0.6million and $0.4million related to the FX201 and FX301 pipeline programs, respectively, due to increased clinical trial activity.

Selling, general and administrative expenses were $27.4million and $24.7million for the three months ended June30, 2021 and 2020, respectively. Selling expenses were $18.9million and $16.8million for the three months ended June30, 2021 and 2020, respectively. The year-over-year increase of $2.1million was primarily due to the partial resumption of industry conferences and physician speaker programs and increases in business travel during the quarter. General and administrative expenses were $8.5million and $7.9million for the three months ended June30, 2021 and 2020, respectively, which represents an increase of $0.6million.

Interest income was $0.2million and $0.1million for the three months ended June30, 2021 and 2020, respectively. Interest expense was $5.2 and $5.0million for the three months ended June30, 2021 and 2020, respectively.

As of June30, 2021, the Company had approximately $131.2million in cash, cash equivalents, and marketable securities compared with $175.3million as of December31, 2020.

Recent News & Business Updates

-- On July30, 2021, the Company entered into a second amendment to its Amended and Restated Credit and Security Agreement with Silicon Valley Bank, MidCap Financial Trust, MidCap Funding XIII Trust, and other lenders, providing for a term loan of up to $55.0million available at closing and a revolving credit facility of up to $25.0million. The Company concurrently borrowed the $55.0million term loan and drew down $20.0million from the revolver, bringing the total balance to $25.0million, and used $48.1million of the proceeds to repay the outstanding 2019 term loan and revolving loans under the existing credit agreement.The applicable interest rate for the term loan under the amended credit facility is the greater of the prime rate plus 2.75% or 6.00%, and the interest rate for the revolving loan is the greater of the prime rate plus 1.75% or 5.00%. Under the credit facility, following an interest-only period ending on August1, 2023, principal is due in equal monthly installments through February1, 2024, which may be extended to July1, 2026, upon satisfaction of certain conditions. The Company estimates that the amended credit facility will result in an approximately $59.0million improvement to cash flow through 2023, net of the term loan proceeds, payment of the outstanding 2019 term loan balance, and deferring principal payments.

-- In July 2021, the Company fully enrolled the SAD portion of the Phase1b proof-of-concept trial evaluating the safety and tolerability of FX301 administered as a single-dose, popliteal fossa block (a commonly used nerve block in foot and ankle-related surgeries) in patients undergoing bunionectomy. Based on the data, a decision will be made whether to expand a selected dose and volume cohort by another 36 patients. Results from this trial are expected by late 2021. -- In June 2021, the SAD part of the open-label, Phase1 trial investigating FX201, an intra-articular gene therapy product candidate for OA knee pain, was fully enrolled. As of August1, 40 patients had been treated across all cohorts, including the expansion groups of the low and mid doses. The most commonly observed treatment-related adverse events (AEs) in the trial have been pain, swelling, and effusion in the injected knee. In the second quarter, the Company made the strategic decision to investigate pretreatment with an intra-articular immediate release steroid prior to FX201 administration in up to 38 patients in expansion groups, as a means to mitigate potential AEs. Enrollment under the amended protocol has commenced, and additional data readouts are anticipated by the end of 2021. -- On July12, 2021, Flexion announced the appointment of Utpal Koppikar to its Board of Directors. -- On June9, 2021, the Company announced the appointment of William T. Andrews, M.D., as Chief Medical Officer. -- On May12, 2021, Flexion announced that Fred Driscoll would rejoin the Company as Chief Financial Officer effective June1, 2021.

About ZILRETTA

On October6, 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 acetonidea commonly administered, short-acting corticosteroidwith a poly lactic-co-glycolic acid (PLGA) matrix to provide extended pain relief. The pivotal Phase3 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 is an investigational gene therapy that utilizes a helper-dependent adenovirus (HDAd) vector devoid of all viral genes that carries a coding sequence for an anti-inflammatory protein called interleukin-1 receptor antagonist (IL-1Ra) under the control of an inflammation-responsive promoter. FX201 is injected directly into the joint space (also termed the intra-articular space) and is intended to deliver as-needed anti-inflammatory activity to joint tissues, with the goal of providing at least 6 to 12 months of meaningful pain relief and functional improvement following a single injection with the possibility of slowing disease progression.

About FX301

FX301 is an investigational locally administered NaV1.7 inhibitor known as funapide, formulated for extended release in a thermosensitive hydrogel. The initial development of FX301 is intended to support administration as a peripheral analgesic nerve block for control of post-operative pain. Flexion believes FX301 has the potential to provide effective pain relief for at least three to five days while preserving motor function.

About Osteoarthritis (OA) of the Knee

OA, also known as degenerative joint disease, is the most common form of arthritis, affecting more than 32.5million adults living in the United States. In 2017, approximately 15million 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.

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.
