Total Q2 2022 revenue of $7.4 million, up 139% from prior year
Recently launched ALKINDI SPRINKLE^® and Carglumic Acid continue to show robust growth
Divestiture of hospital products division to focus on rare disease strategy
U.S. Food and Drug Administration (FDA) Approval of Zonisade™ (zonisamide oral suspension)

DEER PARK, Ill., Aug. 11, 2022 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc (NASDAQ:ETON), an innovative pharmaceutical company focused on developing and commercializing treatments for rare diseases, today reported financial results for the second quarter ended June 30, 2022.

"The second quarter of 2022 was a critical inflection point for the company. With the completion of the hospital products divestiture, we are now 100% focused on our rare disease strategy and are well capitalized to execute on our mission to be a leading rare disease company. Sales of our recently launched ALKINDI SPRINKLE^® remain strong, with 293% year-over-year revenue growth, and feedback from the patient and physician communities continues to be overwhelmingly positive. Carglumic Acid also delivered another impressive quarter, with sales growing 100% sequentially. Physicians and patients appreciate the convenience of the room-temperature-stable product as well as the significant financial savings to the healthcare system compared to the competing product. We believe both products have long runways ahead of them and we are excited about the opportunities to add additional rare disease products to our portfolio this year," said Sean Brynjelsen, CEO of Eton Pharmaceuticals.

Second Quarter and Recent Business Highlights

Sold hospital products for up to $50 million, finalizing Eton's transition to a dedicated rare disease company. In June, Eton sold Biorphen^®, Rezipres^®, and Cysteine Hydrochloride to Dr. Reddy's Laboratories, allowing Eton to focus solely on its rare disease product portfolio.
Reported sixth straight quarter of sequential growth in product sales and royalty revenue. For the second quarter of 2022, Eton reported total revenue of $7.4 million, an increase of 139% over the prior year period. Product sales and royalty revenue were $2.4 million during the quarter, an increase of 316% over the prior year period.
Continued growth in ALKINDI SPRINKLE^®. ALKINDI SPRINKLE sales grew 293% over the second quarter of 2021 and 34% over the first quarter of 2022, demonstrating a strong desire for the low-dose treatment options that ALKINDI SPRINKLE offers.
Strong adoption of Carglumic Acid tablets. Carglumic Acid sales in the second quarter of 2022 grew 100% over the first quarter of 2022. Physicians and patients continue to appreciate the convenience of Eton's room-temperature-stable product and the significant financial savings that the product delivers to the U.S. healthcare system relative to the competing product.
FDA Approval of Zonisade™ (zonisamide oral suspension). In July, Zonisade was approved by the FDA. Azurity Pharmaceuticals will be solely responsible for commercializing the product and Eton will receive a $5 million milestone payment upon launch and an ongoing royalty on commercial sales.
Progressed R&D pipeline to support additional new product launches in coming years. During the quarter, the company made progress addressing the FDA's requests on dehydrated alcohol injection and expects to resubmit the application for the product later this year, which could allow for approval and launch of the product in 2023. The company continues to progress development of ZENEO^® hydrocortisone autoinjector, which could be filed with the FDA in 2023. In addition, the company has initiated development of two additional high-value rare disease products.

Second Quarter Financial Results

Net Sales: Net sales for the second quarter of 2022 were $7.4 million compared with $3.1 million in the prior year period. Net sales included $5.0 million of licensing payments related to the sale of the hospital products division to Dr Reddy's Laboratories during the quarter, and $2.5 million of licensing payments related to the Azurity Pharmaceuticals transaction in the second quarter of 2021.

Product sales and royalty revenue were $2.4 million for the second quarter of 2022 compared with $0.6 for the second quarter of 2021. Product sales and royalty revenue in the second quarter of 2022 were negatively impacted by a $0.2 million inventory allowance adjustment resulting from the divestiture of Rezipres^®. Excluding the impact of this adjustment, product sales and royalty revenue would have increased 351% over the prior year period and 18% over the first quarter of 2022. The increase in product sales and royalty revenue was primarily driven by growth in ALKINDI SPRINKLE and the launch of Carglumic Acid tablets.

Gross Profit: Gross profit for the second quarter of 2022 was $4.6 million compared with $2.9 million in the prior year period. Gross profit for the second quarter of 2022 included $1.8 million of non-cash expenses related to the divestment of the hospital products. The growth was primarily due to increased licensing income, growth in ALKINDI SPRINKLE, and the launch of Carglumic Acid tablets.

General, and Administrative (G&A) Expenses: G&A expenses for the second quarter of 2022 were $5.3 million compared to $3.2 million in the prior year period. Cash G&A expenses for the second quarter of 2022 were $3.9 million, compared to $2.9 million in the prior year period. The increase in cash SG&A expenses was primarily driven by increased employee expenses and increased sales and marketing expenses to support the growth of the company's commercial products.

Research & Development (R&D) Expenses: R&D expenses for the second quarter of 2022 were $0.7 million compared to $2.0 million in the prior year period. The prior year period included a $0.5 million milestone payment related to the company's ZENEO hydrocortisone autoinjector.

Net Income/Loss: Net income for the second quarter of 2022 was a loss of $1.6 million or $0.06 per basic and diluted share compared to a loss of $2.0 million or $0.08 per basic and diluted share in the prior year period.

Cash Position: As of June 30, 2022, the company had cash of $17.0 million. The company is entitled to receive an additional $5.0 million milestone payment upon the launch of the recently approved Zonisade™ product.
