DEER PARK, Ill., Aug. 10, 2023 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc (“Eton” or “the Company”) (Nasdaq: ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, today reported financial results for the quarter ended June 30, 2023.

“With record product sales, the launch of Betaine Anhydrous, and positive cash flow and earnings, Eton’s second quarter was exceptional. It was the company’s tenth straight quarter of sequential product revenue growth, driven by robust demand and record results for ALKINDI SPRINKLE® and Carglumic Acid. Given our strong performance through the first half of the year, we have increased our revenue expectation and now anticipate reaching approximately $30 million in total revenue this year,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals.

“With attractive growth prospects for our existing commercial products, the targeted 2024 launch of ET-400, and the financial resources to continue adding new products, Eton is very well positioned to deliver long-term growth and achieve our goal of having 10 commercial rare disease products on the market by the end of 2025,” concluded Brynjelsen.

Second Quarter and Recent Business Highlights

Tenth straight quarter of sequential growth in product sales and royalty revenue. Eton reported second quarter 2023 product sales and royalty revenue of $6.5 million, representing 175% growth over the prior year period and 22% growth over the first quarter of 2023.

Record sales of ALKINDI SPRINKLE. ALKINDI SPRINKLE saw another record revenue quarter. The Company’s goal is to reach 400 active patients by the end of the year.

Record sales of Carglumic Acid. Carglumic Acid also posted another quarter of record revenue. The product is benefiting from the Company’s recently expanded sales force as well as the launch of Betaine Anhydrous, which shares the same prescriber base and has resulted in increased interactions with metabolic geneticists.

Strong launch of Betaine Anhydrous. Betaine Anhydrous was launched in May and has already seen strong adoption by patients. The Company’s Eton Cares patient support program has received favorable reviews from both patients and prescribers.

Product candidate ET-400 on track for an NDA submission in Q4 2023. The Company is preparing for an NDA submission in the fourth quarter, which could result in an approval and commercial launch in 2024. ET-400 is a proprietary liquid formulation of hydrocortisone that, if approved, would be sold alongside ALKINDI SPRINKLE, and would provide patients with an additional treatment option. The Company believes ET-400 will accelerate patient adoption, with total combined peak sales of ALKINDI SPRINKLE and ET-400 expected to exceed $50 million annually.   

Monetized royalty interests and strengthened financial position. During the quarter, Eton sold its remaining milestone and royalty interests in ZONISADE®, EPRONTIA®, and the lamotrigine product candidate. In exchange for its interests, Eton received a payment of $5.5 million, which it intends to reinvest in the acquisition of rare disease products. In the second quarter, the company also received a $0.8 million break-up fee associated with its participation as the stalking horse bidder in an auction process. The Company finished the quarter with $21.6 million of cash and cash equivalents.

Second Quarter Financial Results

Net Revenue: Net sales for the second quarter of 2023 were $12.0 million compared with $7.4 million in the prior year period. Net sales included $5.5 million of licensing payments received during the quarter related to the sale of Eton’s neurology product royalties and milestones to Azurity Pharmaceuticals, compared to $5.0 million of licensing revenue in the prior year period related to the sale of multiple hospital products to Dr. Reddy’s.

Product sales and royalty revenue were $6.5 million for the second quarter of 2023 compared with $2.4 million in the prior year period, an increase of 175% over the prior year period and 22% over the first quarter of 2023. The year-over-year increase in product sales and royalty revenue was primarily driven by growth in ALKINDI SPRINKLE and Carglumic Acid tablets.

Gross Profit: Gross profit for the second quarter of 2023 was $9.7 million compared with $4.6 million in the prior year period. The growth was driven by the sale of the Company’s neurology product royalties as well as growth in ALKINDI SPRINKLE and Carglumic Acid. Gross profit for the prior year period included $1.8 million of non-cash expenses related to the hospital products divestment.

Research and Development (R&D) Expenses: R&D expenses for the second quarter of 2023 were $1.1 million compared to $0.7 million in the prior year period. The increase was primarily due to a $0.5 million milestone payment resulting from the successful manufacturing of registration batches of product candidate ET-600.

General and Administrative (G&A) Expenses: G&A expenses for the second quarter of 2023 were $4.7 million compared to $5.3 million in the prior year period. The decrease in G&A expenses was mainly due to decreased FDA fees and legal fees associated with products sold to Dr. Reddy's in June 2022.

Net Income: Net income for the second quarter of 2023 was $4.6 million or $0.18 per basic and diluted share compared to a net loss of $1.6 million, or $0.06 per basic and diluted share in the prior year period.

Cash Position: As of June 30, 2023, the Company had cash and cash equivalents of $21.6 million.
