Management to hold conference call today at 4:30pm ET

DEER PARK, Ill., March 16, 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 December 31, 2022.

"The fourth quarter was another impressive quarter for Eton, fueled by the continued momentum of ALKINDI SPRINKLE and Carglumic Acid. It was our eighth straight quarter of sequential revenue growth in product and royalty revenue, and we expect that strong growth to continue throughout 2023 and beyond," said Sean Brynjelsen, CEO of Eton Pharmaceuticals.

"Our excitement level for 2023 could not be higher and we believe we can at least double our product sales and royalty revenue this year. ALKINDI SPRINKLE and Carglumic Acid were already poised to deliver major growth in 2023, and we have now completed our sales force expansion, which is expected to accelerate their growth, plus we have the planned launch of Betaine in the coming weeks and the anticipated launch of dehydrated alcohol injection later in the year," concluded Brynjelsen.

Fourth Quarter and Recent Business Highlights

Eighth straight quarter of sequential growth in product sales and royalty revenue. Eton reported fourth quarter 2022 product sales and royalty revenue of $3.5 million, representing 220% growth over the prior year and 9% growth over the third quarter of 2022. Fourth quarter 2022 product sales were negatively impacted by a slowdown in new patient adds during the holiday season and the timing of ALKINDI SPRINKLE® product orders from the Company's specialty pharmacy customer. The Company expects the sequential growth rate to increase in the first quarter of 2023 compared to the fourth quarter of 2022.

Launch of Eton's expanded rare disease sales force. In January 2023, Eton exercised its right to exit its ALKINDI SPRINKLE co-promotion agreement. Given the significant growth of ALKINDI SPRINKLE in 2022 and the expected growth in 2023, the sales commission to Eton's co-promotion partner was expected to be approximately the same cost as internally expanding to a full-sized sales force. Eton's sales force is now fully staffed with twelve rare disease specialists that have been deployed into the field. The new sales force will be solely focused on Eton's products and will allow Eton to exercise significantly greater control over sales force strategies, incentive plans, and personnel decisions. In addition to providing greater attention to ALKINDI SPRINKLE, the sales force will increase the promotional presence of Carglumic Acid and support the upcoming launch of Betaine.

Continued strong growth of Carglumic Acid. The Company's Carglumic Acid product, which was FDA-approved in October 2021 for the treatment of hyperammonemia due to N-acetylglutamate synthase deficiency, continued to see increased adoption in the fourth quarter of 2022, and the product is off to a strong start in 2023, with notable new patient adds. The launch of Betaine is expected to help drive additional interactions with key metabolic geneticists and may provide benefits to Carglumic Acid prescriptions.

Increasing adoption of ALKINDI SPRINKLE. ALKINDI SPRINKLE, which is FDA-approved for the treatment of pediatric patients with adrenocortical insufficiency, saw strong growth of active patients in the fourth quarter of 2022. The Company expects the product's future growth rate to benefit from the new dedicated sales force. The Company also launched a new direct-to-consumer marketing campaign in the first quarter of 2023.

Actively preparing for Betaine Anhydrous launch. The product, which Eton acquired in late 2022 and is FDA-approved for the treatment of homocystinuria, is expected to be commercially available in the coming weeks. The product's launch inventory has been manufactured is and now undergoing final packaging and release testing. The Company has already received strong interest in the product from patients, prescribers, and advocacy groups.

Acquired rare disease product candidate ET-600. Earlier this week, Eton announced the acquisition of an innovative product candidate targeting a rare pediatric endocrinology condition. Eton expects to file a New Drug Application (NDA) for the product in the second quarter of 2024.

Completed Dehydrated Alcohol Injection Submission. In the fourth quarter, the Company submitted a response to the U.S. Food and Drug Administration (FDA) for its dehydrated alcohol injection NDA for the Orphan Drug Designated condition of methanol poisoning. The submission was accepted for review and assigned a target action date of June 27, 2023. Eton is actively working with its commercialization partner on launch preparation activities. Based on IQVIA data, the market for dehydrated alcohol injection is more than $70 million annually.

Continued progress on ET-400. ET-400 is an innovative, patent pending product candidate. If approved, the Company would promote the product alongside ALKINDI SPRINKLE, and it would be expected to help the Company more rapidly penetrate the $100 million market opportunity in pediatric adrenal insufficiency. Eton expects to submit an NDA for the product by the end of 2023, which could allow for an approval and launch of the product in 2024.

Fourth Quarter Financial Results

Net Revenue: Net revenues for the fourth quarter of 2022 were $8.5 million compared with $6.1 million in the prior year period, driven by growth in ALKINDI SPRINKLE and the launch of Carglumic Acid in December 2021. Both periods included $5.0 million in licensing revenue as a result of milestone payments received from Azurity Pharmaceuticals.

Gross Profit: Gross profit for the fourth quarter of 2022 was $6.4 million compared with $5.7 million in the prior year period.
