DEER PARK, Ill., May 12, 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 first quarter ended March 31, 2022.

"We are proud to report our fifth straight quarter of sequential growth in product sales. We expect this growth to continue for the foreseeable future as our commercial products are still in the early stages of launch, and we expect many additional product launches later this year," said Sean Brynjelsen, CEO of Eton Pharmaceuticals, "In addition to the strong commercial results, we have recently made significant progress on the development side with the approval of cysteine injection and the FDA submission for our Biorphen vial product candidate," added Brynjelsen.

Major Business Highlights

Reported a fifth straight quarter of sequential growth in product sales and royalty revenue. For the first quarter of 2022, Eton reported revenue of $2.2 million from product sales and royalties, representing a 100% increase from the fourth quarter of 2021.
Received final approval for cysteine injection. In April, the U.S. Food and Drug Administration (FDA) approved Eton's abbreviated new drug application for cysteine injection. The product-related Paragraph IV trial occurred in March 2022, and a judge's decision is expected by August 2022. If the outcome is successful, Eton plans to launch the product shortly after the judge's decision.
Submitted Prior Approval Supplement for Biorphen® vial. The supplement to add the vial container system was submitted in April 2022. The FDA has assigned an August 2022 target action date for the submission.
Announcing development of Biorphen® (phenylephrine) premix bag. Eton announced the development of a Biorphen® premix bag. The product offering would address a significant unmet need in the market. Currently, many hospitals purchase premixed phenylephrine from compounding pharmacies. The product's New Drug Application (NDA) is expected to be submitted in the third quarter of 2022.

Commercial Update

Eton's carglumic acid product launched in late-December 2021 and has received a favorable reception from patients and physicians. Patients appreciate the product's room-temperature stability compared to the competing product's refrigeration requirement. Numerous patients initiated treatment with carglumic acid in the first quarter, and more have initiated since the quarter end. Eton continues to believe it can capture 25-35% market share before the end of the year. The current market is estimated to be more than $50 million annually.

ALKINDI SPRINKLE® continues to grow and reported record quarterly revenue. More new patients initiated ALKINDI SPRINKLE® in the first quarter than any other quarter since the launch of the product. Eton's co-promotion agreement with Tolmar Pharmaceuticals was fully implemented in January, which positively impacted product growth in the first quarter.

ALKINDI SPRINKLE® and carglumic acid continue to see strong growth and both posted record monthly revenue in April. The company expects 2022 revenue of at least $25 million, including $10 million of milestone payments and $15 million of product sales and royalties.

Portfolio Update

Eton now has seven FDA-approved products, six of which are being commercialized and are in launch phase. The company also has three additional products that have been submitted to the FDA, which are expected to be approved and launched in the coming quarters.

Biorphen® (phenylephrine) Premix for Injection. Eton announced the development of a premix Biorphen bag product candidate. The company believes this product would address a significant unmet need and large market opportunity. Currently, hospitals frequently purchase premixed bags from compounding pharmacies. Eton expects the NDA for the product candidate to be submitted by the third quarter of 2022.

Zonisamide Oral Suspension. In April, the product's contract manufacture received notice that the January 2022 FDA site inspection has been officially closed and the facility was deemed ready for commercial manufacturing. As a result, Eton expects the application to be approved on its newly assigned PDUFA date of July 18^th.

Lamotrigine for Suspension. Eton's partner submitted the product-related human factors study results to the FDA in the fourth quarter of 2021, and the application has been assigned a PDUFA date of May 30^th.

Biorphen® Vial. The Prior Approval Supplement for Biorphen® vials has been submitted to the FDA and the application has been assigned a target action date of August 4, 2022.

Rezipres® Vial. The Prior Approval Supplement for Rezipres® vials is expected to be submitted to the FDA later this month.

Dehydrated Alcohol Injection. Eton continues to work on addressing the FDA's requests regarding the dehydrated alcohol injection product application. Eton had additional communications with the agency earlier this month and remains confident that all requests received from the agency are addressable.

Zeneo® Hydrocortisone Autoinjector. Development activities are ongoing, and the product remains on pace for an expected New Drug Application submission in 2023.

Financial Results

Revenue: Eton reported product sales and royalty revenue of $2.2 million for the first quarter of 2022, compared with $0.4 million in the prior year period. The revenue increase was primarily due to growth in ALKINDI SPRINKLE® and the launch of carglumic acid and Rezipres®. Eton reported no licensing revenue in the first quarter of 2022, compared with $11.5 million in the prior year period.

Research and Development (R&D) Expenses: R&D expenses for the first quarter of 2022 were $1.6 million compared with $0.9 million in the prior year period. R&D expenses in the first quarter of 2022 included a $0.5 million milestone related to the Zeneo® hydrocortisone autoinjector.

Selling, General and Administrative (SG&A): SG&A expenses were $4.9 million in the first quarter of 2022, compared to $4.1 million in the prior year quarter. The increased expenses were driven by higher compensation expenses to support sales and quality assurance on commercial products as well as legal expenses associated with the cysteine Paragraph IV trial.

Net Income: Eton reported a net loss of $5.3 million for the first quarter of 2022, compared with a net income of $5.1 million in the prior year period. Eton reported diluted earnings per share (EPS) of ($0.21) in the first quarter of 2022, compared with $0.19 in the first quarter of 2021. The prior year period included the benefit of $11.5 million in licensing revenue.

Cash Position: Cash and cash equivalents were $15.2 million as of March 31, 2022.
