SPARTA, N.J., Nov. 10, 2022 (GLOBE NEWSWIRE) -- PLx Pharma Inc. (NASDAQ:PLXP) ("PLx" or the "Company"), is a commercial-stage drug delivery platform technology company focused on its clinically-validated and patent-protected PLxGuard™ that has the potential to improve the absorption of many drugs currently on the market and to reduce the risk of stomach injury associated with certain drugs. The Company, with its lead products VAZALORE 81 mg and VAZALORE 325 mg liquid-filled aspirin capsules (referred to together as "VAZALORE^®"), announced today certain financial and operational results for the three months ended September 30, 2022, and provided other business updates.

"During the first year of VAZALORE launch, we have invested in building a base of awareness among consumers and healthcare professionals," said PLx's President & CEO Natasha Giordano. "Since market acceptance and sales have taken longer than anticipated to develop, we have streamlined our investments, with the goal of maintaining our base consumption levels. We also recently initiated a formal process to evaluate strategic alternatives, to ensure that VAZALORE can remain available for the millions of patients who need it."

Highlights of Third Quarter and Other Recent Events

Partnered with two large healthcare systems to incorporate VAZALORE into their "Meds to Beds" cardiovascular discharge programs. The goal is to replicate these programs in other healthcare systems nationwide.
Expanded reach efficiently to both heart health and pain relief consumer audiences with introduction of VAZALORE ads on Facebook; ads featuring professional baseball legend John Smoltz's personal experience with VAZALORE 325 mg for fast, effective pain relief were well received and delivered high engagement levels, beating industry benchmarks by four-times.
Expanded non-personal promotional efforts to over 3,000 cardiologists and neurologists nationwide who opted-in to receive VAZALORE educational materials; materials included clinical study results for healthcare professionals and samples, education brochures and coupons for patients; program slated to run through 1Q 2023.
Executed targeted digital campaign to over 500,000 healthcare professionals (HCPs), to include cardiologists, pharmacists, and advanced practice providers; message focused on VAZALORE benefits compared with other formulations as key reason to recommend; open rates across all target audiences performed above industry benchmarks.
Distributed VAZALORE samples and patient education materials to more than 1,000 HCPs who have adopted and are actively recommending VAZALORE in their practices.
Completed final stage of broad reach consumer email campaign; communication focused on how VAZALORE is different from other aspirin formulations; engagement level exceeded benchmark.

Third Quarter 2022 Financial Highlights

Total revenues for the third quarter of 2022 were $0.4 million and included $0.3 million of unfavorable adjustments for additional trade allowances and incremental sales returns reserves. The increased trade allowances are used to promote sell through of existing retail inventory. The increased sales returns reserve reflected excess inventory at certain retailers. Sales in the prior year period of $6.6 million benefitted from the commercial launch and initial distribution of VAZALORE to US retail channels. The VAZALORE 81 mg dose (consisting of two SKUs) represented 58% of the current period net sales versus 67% of net sales in the prior year period.

Cost of sales for the third quarter of 2022 were $1.5 million and reflected costs related to outsourced manufacturing and packaging, shipping, quality assurance and royalties. Cost of sales also included $1.0 million of incremental costs related to expired packaging materials, higher shipping costs, and inventory obsolescence for product not expected to be sold prior to its shelf-life date, which is 12 months prior to expiry.

Total operating expenses were $9.8 million for the third quarter of 2022, a decline of approximately 22%, compared to $12.6 million in the prior year period. The significant cost savings reflected the non-recurrence of prior year costs associated with the commercial launch of VAZALORE, coupled with the Company's disciplined spending approach, including reductions in sales and marketing expenses.

Research and development (R&D) expenses declined approximately 60% to $0.6 million in the third quarter of 2022, compared to approximately $1.6 million in the third quarter of 2021. The decrease primarily reflected the non-recurrence of prior year costs for pre-commercial manufacturing-related activities, such as validation and optimization work for VAZALORE. R&D expense in the current period included scale up manufacturing activities to increase capacity and lower cost of inventory.

Selling, marketing and administrative (SM&A) expenses of $9.1 million declined approximately 17% in the third quarter of 2022, compared to $11.0 million in the third quarter of 2021. The prior year period included higher costs associated with extensive VAZALORE launch activities, including deployment of a cardiovascular specialty field force and a national media television campaign. Sequentially, SM&A expenses declined approximately 33%, compared to the second quarter of 2022, due to lower media spending, the significant reduction in the Company's Cardiovascular Care Specialist team and a shift to more cost efficient nonpersonal promotional activities, such as virtual and digital communications. Non-cash stock-based compensation was $1.1 million, compared to $0.7 million in the third quarter of 2021.

Other income (expense), net totaled $2.3 million of other income during the third quarter of 2022, compared to other expense of $11.8 million in the third quarter of 2021. The increase is largely attributable to the non-cash change in fair value of warrant liability, primarily due to the fluctuation of the price of the Company's common stock.

Net loss attributable to common stockholders for the third quarter of 2022 was $8.5 million, or a loss of ($0.30) per diluted share, compared to a net loss of $21.6 million, or ($0.80) per diluted share in the prior year period.

Adjusted non-GAAP net loss per diluted share was ($0.37) in the third quarter of 2022, compared to an adjusted net loss of ($0.37) per diluted share in the third quarter of 2021.

Non-GAAP Measures

PLx's management considers adjusted non-GAAP net loss and adjusted non-GAAP net loss per basic and diluted earnings per share to be important financial indicators of operating performance, providing investors and analysts with useful measures of operating results unaffected by the impact on the financial statements of the volatility of the change in the fair value of the warrant liability and non-cash and non-recurring dividends and beneficial conversion features on our preferred stock. Management uses adjusted non-GAAP net loss and adjusted non-GAAP net loss per share when analyzing performance. Adjusted non-GAAP net loss and adjusted non-GAAP net loss per share should be considered in addition to, but not in lieu of net loss or net loss per share reported under GAAP.
