DEER PARK, Ill., Aug. 06, 2019 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc. (Nasdaq: ETON), a specialty pharmaceutical company focused on developing and commercializing innovative drug products, reported financial results for the second quarter ended June 30, 2019 and provided an update on business progress.

“We made significant progress in the second quarter expanding and advancing our portfolio of late-stage product candidates, including the acquisition of ET-105, which added an additional high-value, near-term product launch to our portfolio,” said Sean Brynjelsen, Chief Executive Officer of Eton Pharmaceuticals. “We are at an exciting inflection point as we anticipate becoming a commercial revenue generating company in the coming months. Our team is focused on preparing our commercial operations for the potential approvals of ET-202, our ready-to-use phenylephrine injection, in October of this year and ET-105, our patent-pending lamotrigine candidate, in March of 2020. We are also pleased to announce for the first time today that ET-203’s NDA has been submitted to the FDA, and if approved, could provide an additional mid-2020 product launch.”

Recent Business Milestones and Updates:

Initiated clinical study of ET-104. In April 2019, Eton initiated a bioequivalence study for ET-104, one of the company’s patent-pending oral liquid neurology products. Eton anticipates receiving study results in the third quarter of 2019. Pending the successful completion of the study, Eton expects to submit the product’s NDA before year end.
Acquired U.S. rights to ET-105. In June 2019, Eton acquired the U.S marketing rights to ET-105 from Aucta Pharmaceuticals. ET-105 is an innovative patent-pending formulation of lamotrigine to be delivered to patients as an oral liquid for the treatment of various forms of epilepsy. An NDA for ET-105 has been filed with the U.S Food and Drug Administration (FDA) and was assigned a PDUFA date of March 17, 2020. Lamotrigine is one of the most widely used anti-epilepsy medications with U.S sales exceeding $700 million annually but is currently only FDA-approved in tablet formulations.
EM-100 Received Complete Response Letter from the FDA. As previously announced in July 2019, Eton’s partner, Bausch Health, received a Complete Response Letter (CRL) for EM-100. Eton believes that all of the FDA’s questions are addressable and expects Bausch Health to respond to the CRL within the coming months.
ET-203 New Drug Application was submitted. In late July 2019, the NDA for ET-203 was submitted to the FDA. ET-203 is a ready-to-use formulation of a widely used and frequently compounded injectable product. ET-203 is expected to be complementary to Eton’s ET-202, which has been assigned a PDUFA date of October 21, 2019.

Pipeline Update:

Eton currently has four products submitted to the FDA and seven additional product candidates in late-stage development, three of which are expected to be submitted to the FDA before year end:

ET-104: Eton expects bioequivalence study results by September 2019. If the study is successful, Eton expects to submit an NDA for ET-104 in the fourth quarter of 2019.

DS-300: DS-300 was previously submitted to the FDA as an NDA under a Rolling Review. As previously disclosed, the FDA has requested that Eton re-file the DS-300 application as an ANDA due to the approval of a competing product with the same molecule. Eton remains in discussions with the FDA for clarity on the pathway. If the application is required to be re-filed as an ANDA, Eton expects to submit the application before year end.

ET-103: Eton expects bioequivalence study results by September 2019. If the study is successful, Eton expects to submit an NDA for ET-103 in the fourth quarter of 2019.

Second Quarter Financial Results

Revenue: Eton reported no revenue in the second quarter of 2019 and no revenue for the same period in 2018.

Research and Development (R&D) Expenses: R&D expenses were $1.4 million for the second quarter of 2019 versus $1.7 million for the same period in 2018. The decline was primarily driven by reduced product-specific development costs in the period, partially offset by increased costs associated with headcount and the operation of the company’s R&D laboratory facility that was set up in late 2018.

General and Administrative (G&A) Expenses: G&A expenses were $1.9 million for the second quarter of 2019 versus $1.0 million for the same period in 2018. The increase was primarily driven by higher employee-related costs from increased headcount, public company expenses, and marketing expenses associated with product launch preparation activities. Excluding non-cash expenses, G&A expenses for the quarter were $1.5 million versus $0.6 million in the prior year period.

Net Loss: Eton reported a net loss for the second quarter of 2019 of $3.2 million versus $3.1 million for the same period of 2018.

Cash Position: As of June 30, Eton reported cash and cash equivalents of $14.9 million compared to $26.7 million as of December 31, 2018 and $19.6 million as of March 31, 2019. Subsequent to the quarter-end, in early July, Eton received a $1.3 million refund from the FDA for an NDA filing fee which had been paid in March 2019.
