Eton Pharmaceuticals Announces Third Quarter Financial Results and Highlights Business Progress

  • Biorphen® Expected to Launch by End of November
  • Company to Host Conference Call and Webcast Today at 4:30 p.m. ET (3:30 p.m. CT)

DEER PARK, Ill., Nov. 14, 2019 (GLOBE NEWSWIRE) -- Eton Pharmaceuticals, Inc (Nasdaq: ETON), a specialty pharmaceutical company focused on developing and commercializing innovative drug products, today reported financial results for the third quarter ended September 30, 2019 and provided an update on business progress.

“Our first product approval was a major milestone for Eton and a great accomplishment by our team,” said Sean Brynjelsen, Chief Executive Officer of Eton Pharmaceuticals. “Initial interest in Biorphen from hospitals has been strong, and we expect to have the product available for customers before the end of this month. We also continued to make progress advancing our pipeline this quarter, as we work towards additional product launches in 2020.”

Recent Business Milestones and Updates:

  • FDA approval of Biorphen. On October 21st, the FDA approved Biorphen, the first and only FDA-approved ready-to-use formulation of phenylephrine for the treatment of clinically important hypotension resulting primarily from vasodilation in the setting of anesthesia.
  • Executed debt transaction with SWK Holdings. This week, Eton announced it has secured a $10 million debt facility from SWK Holdings. The facility will give the company additional flexibility to pursue accretive business development activities while it invests in the commercial launch of Biorphen and the planned launch of ET-105 in early 2020.
  • Licensed U.S marketing rights to ET-105. During the quarter, Eton closed the acquisition of U.S marketing rights to ET-105, which was executed upon the product’s NDA being accepted for review by the FDA. ET-105 is an innovative formulation of lamotrigine that will be administered to patients as an oral liquid, and its NDA has been assigned a PDUFA date of March 17, 2020.

Biorphen Commercial Launch

Eton currently has a team of five hospital-focused sales representatives actively promoting Biorphen and expects to expand the team to more than ten representatives by the first quarter of 2020. Since approval, Eton’s team has promoted Biorphen and met with key opinion leaders at conferences including the American College of Emergency Physicians (ACEP) and the American Society of Anesthesia (ASA), and has already engaged in discussions with pharmacy directors or physicians from more than 200 different institutions.

Eton estimates that the current phenylephrine injectable market is greater than 20 million Biorphen equivalent units per year. Over time, Eton expects to convert a significant share of the market to ready-to-use Biorphen, and in addition, expects to grow the market for phenylephrine as Biorphen’s three-year shelf life allows it to be stocked in additional locations throughout emergency rooms, crash carts, and in surgical centers where it previously was not feasible to stock ready-to-use phenylephrine due to the short expiry dating of compounded products.

Currently, ready-to-use phenylephrine injection is only available from 503B compounding pharmacies. Eton believes there is no longer a clinical need for 503B facilities to compound phenylephrine into ready-to-use formulations, and based on FDA guidelines, also believes 503B facilities would be in breach of FDA policy if they continue to sell ready-to-use phenylephrine injection after the availability of Biorphen.

Eton currently has eight product candidates in its late-stage pipeline, which the company defines as products that are expected to be submitted to the FDA within twelve months.

EM-100. Eton’s partner is finalizing an amendment to respond to the items addressed in the FDA’s Complete Response Letter, and the amendment is scheduled to be submitted before the end of November. Eton expects the amendment to be classified as a minor amendment, which would be assigned a three-month target action goal date by the FDA, allowing for a potential approval as early as the first quarter of 2020.

ET-105. The FDA review of ET-105 is ongoing and has been assigned a PDUFA date of March 17, 2020. Eton has proactively initiated a human factors study to support the filing and mitigate the potential for a delay in the approval timing. The human factors study is expected to be completed in January and will be added to the submission under review.

DS-300. Eton expects to submit the ANDA for DS-300 before the end of this year.

ET-203. Eton’s partner has an FDA meeting scheduled to discuss options to address the concerns raised by the FDA regarding the original NDA submission. Eton believes the NDA will be resubmitted in the coming months.

ET-103. Eton has submitted the ET-103 clinical protocol to the FDA for review prior to the submission of its NDA. The company expects to receive FDA feedback in December 2019. If the protocol is acceptable, Eton would expect to file the NDA in the first quarter of 2020.

ET-104. Eton is in active discussions with the FDA regarding the product’s pediatric requirements and expects to submit the NDA in the first half of 2020.

DS-100. Eton held a meeting with the FDA in August 2019. Based on the positive meeting outcome, the company expects the product’s NDA to be submitted in 2020.

ET-101. Eton anticipates initiating ET-101’s bioequivalence study in the first quarter of 2020. If successful, Eton would anticipate submitting the product’s NDA in 2020.

Third Quarter Financial Results

Research and Development (R&D) Expenses: R&D expenses were $3.4 million for the third quarter of 2019 versus $1.5 million for the same period in 2018. The increase was primarily due to a $2.0 million licensing payment to acquire marketing rights to ET-105 and increased costs associated with headcount and the operation of the company’s R&D laboratory facility that was established in late 2018, partially offset by reduced product-specific development costs in the period.

General and Administrative (G&A) Expenses: G&A expenses were $1.6 million for the third quarter of 2019 versus $0.8 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.

Net Loss: Eton reported a net loss for the third quarter of 2019 of $5.0 million versus $2.9 million for the same period of 2018.

Cash Position: As of September 30, Eton reported cash and cash equivalents of $11.8 million compared to $26.7 million as of December 31, 2018.
