  • Acquired ultra-rare disease product Nitisinone Capsules
  • Management to hold conference call today at 4:30pm ET

DEER PARK, Ill., Nov. 09, 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 September 30, 2023.

“The momentum continues for Eton, and we’re proud to report our eleventh straight quarter of product sales and royalty revenue growth, which has allowed us to reach cash flow break-even ahead of schedule. Sales of ALKINDI SPRINKLE® and Carglumic Acid remain strong, and we recently added a fourth commercial rare disease product to our portfolio, Nitisinone Capsules, which we expect to launch in early 2024,” said Sean Brynjelsen, CEO of Eton Pharmaceuticals.

“Reaching cash flow break-even is an important milestone on our journey to becoming a highly profitable and industry leading rare disease company. I am proud of the hard work and dedication from our employees that made it possible. With strong organic growth prospects for our existing commercial products, the potential near-term launches of Nitisinone and ET-400, plus a strong balance sheet and favorable M&A environment, I couldn’t be more excited about Eton’s outlook for 2024 and beyond,” concluded Brynjelsen.

Third Quarter and Recent Business Highlights

Eleventh straight quarter of sequential growth in product sales and royalty revenue. Eton reported third quarter 2023 product sales and royalty revenue of $7.0 million, representing 118% growth over the prior year period and 8% growth over the second quarter of 2023.

Recorded positive cash flow from operations solely from product sales and royalty revenue. During the quarter, cash on hand increased from $21.6 million to $22.1 million.

Strong growth in product sales driven by ALKINDI SPRINKLE and Carglumic Acid. Both products posted strong year-over-year and quarter-over-quarter sales growth. The Company expects to launch an ALKINDI SPRINKLE physician sampling program in the coming weeks, which is expected to further accelerate the product’s growth.

Acquired FDA-approved ultra-rare disease product Nitisinone. In October, Eton acquired Nitisinone capsules which will be Eton’s fourth commercial product, moving the company closer to its goal of reaching ten commercial products by the end of 2025. Eton expects to launch the product during the first quarter of 2024.

First full quarter of commercial availability for Betaine Anhydrous. The launch of Betaine resulted in a significant increase in the company’s interactions with metabolic geneticists, which is expected to help drive Betaine revenue as well as potentially benefit Carglumic Acid and the company’s soon-to-be-launched Nitisinone product.

Held pre-NDA meeting with FDA regarding product candidate ET-400. Last week, Eton held a pre-NDA meeting with the FDA regarding ET-400. Based on feedback from the meeting, the company plans to run an additional bioequivalence study and submit the NDA in the middle of 2024. ET-400 is a proprietary liquid formulation of hydrocortisone that, if approved, would complement ALKINDI SPRINKLE by providing patients with an additional treatment option. The Company believes that the combined peak sales of ET-400 and ALKINDI SPRINKLE could exceed $50 million annually.

Third Quarter Financial Results

Net Revenue: Net sales for the third quarter of 2023 were $7.0 million compared with $3.2 million in the prior year period, an increase of 118%. Net sales were comprised entirely of product sales and royalties in both periods. The year-over-year increase was primarily driven by growth in ALKINDI SPRINKLE and Carglumic Acid tablets. Product sales and royalty revenue for the third quarter of 2023 were up 8% over the second quarter of 2023.

Gross Profit: Gross profit for the third quarter of 2023 was $4.4 million compared with $2.0 million in the prior year period.

Research and Development (R&D) Expenses: R&D expenses for the third quarter of 2023 were $0.6 million compared to $0.7 million in the prior year period. The decrease was primarily due to decreased expenses associated with products sold to Dr. Reddy's in 2022.

General and Administrative (G&A) Expenses: G&A expenses for the third quarter of 2023 were $4.3 million compared to $4.2 million in the prior year period. The slight increase in G&A expenses was mainly due to increased employee-related expenses related to sales force expansion offset by decreased sales and marketing expenses associated with third party sales commissions.

Net Loss: Net loss for the third quarter of 2023 was $0.6 million or $0.02 per basic and diluted share compared to a net loss of $3.0 million, or $0.12 per basic and diluted share, in the prior year period.

Cash Position: As of September 30, 2023, the Company had cash and cash equivalents of $22.1 million.
