The Company is executing a fully integrated, multi-channel commercial strategy for VAZALORE, including a three-pronged approach focused on healthcare professionals, retailers, and consumers. The combined efforts of its cardiovascular care specialists, medical communications, product display support, and national media campaign are yielding favorable results across several measures including:
- Retail consumption: VAZALORE continues to gain momentum, with strong unit and dollar growth over the last several consecutive four-week periods¹.
- Number three brand: VAZALORE has gone from having zero brand awareness among consumers less than six months ago, to becoming the number three brand in the Aspirin Heart Health Segment, on a dollar-share basis².
- Advertising effectiveness: Through mid-January 2022, the Company's national media campaign for VAZALORE had delivered more than 500 million impressions, reaching more than 90% of its target audience, or nearly 15 million consumers, with high frequency.³
- Field force effectiveness: The Company's cardiovascular care specialists, coupled with medical communications support, are effectively targeting healthcare professionals ("HCPs"), affiliated with the top 100 heart/stroke hospitals in the U.S., and reaching 98% of their top group practices.⁴ The field force is also expanding its coverage within existing territories to include surrounding practices.
The Company has been engaging and building advocacy with more than 100 regional and national cardiovascular thought leaders across the U.S. through various medical communications programs. Important scientific data supporting VAZALORE's pharmacokinetic and pharmacodynamic profile has also been presented.
The Company has been supporting Heart Health Awareness and the benefits of aspirin therapy in secondary prevention of heart attack or clot-related stroke.
The Company has implemented the National Advertising Division's ("NAD") recommendations associated with the VAZALORE television commercial and online advertising to health care professionals and consumers.
- The NAD closed its compliance proceeding for PLx on January 27, 2022, and the Federal Trade Commission subsequently determined not to take additional action.

Fourth Quarter 2021 Financial Highlights

Total revenues for the fourth quarter of 2021 were $1.6 million, compared to no revenue in the fourth quarter of 2020, reflecting the timing of trade re-orders following the strong initial sales distribution of VAZALORE into U.S. retail channels in the third quarter of 2021. Net sales of the 81 mg dose (consisting of a 12 count and 30 count SKU), represented approximately 86% of total net sales in the fourth quarter of 2021.

Gross margin of 44% reflected a slight sequential improvement from the third quarter of 2021, due to favorable product mix consisting of higher sales of VAZALORE 81mg. Cost of goods in the fourth quarter of 2021 primarily reflected outsourced manufacturing and packaging costs, combined with costs related to shipping, quality assurance and royalty payments.

Total operating expenses were $21.6 million during the fourth quarter of 2021, compared to operating expenses of $3.7 million for the prior year period, reflecting increased promotional activities and expenses associated with the commercial launch of VAZALORE during the third quarter of 2021.

Research and development expenses declined approximately 43% to $0.7 million in the fourth quarter of 2021, and included costs associated with the VAZALORE 81 mg clinical study and scale-up of manufacturing activities. In the prior year period, research and development expenses were $1.2 million, and included costs associated with manufacturing and validation work to support the sNDA filings for VAZALORE.

Selling, marketing and administrative expenses totaled $20.9 million in the fourth quarter of 2021, compared to $2.5 million in the prior year period, primarily due to higher sales and marketing expenses associated with the commercial launch of VAZALORE and increased non-cash stock-based compensation. The higher year-over-year expense also included a new cardiovascular specialty field force and national media television campaign, which were launched during the third quarter of 2021.

Other income (expense), net totaled $24.4 million of other income during the fourth quarter of 2021, compared to other expense of $4.2 million in the fourth quarter of 2020. The variance 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 income attributable to common stockholders for the fourth quarter of 2021 was $3.6 million, or a loss of ($0.73) per diluted share, compared to a net loss of $8.5 million, or ($0.87) per diluted share in the prior year period.

Adjusted non-GAAP net loss per diluted share was ($0.73) in the fourth quarter of 2021, compared to an adjusted net loss of ($0.38) per diluted share in the fourth quarter of 2020.

Full Year 2021 Financial Highlights

For the full year ended December 31, 2021, total revenue was $8.2 million, compared with total revenue of $30,000 in 2020, reflecting initial sales of VAZALORE following the strong initial sales distribution of VAZALORE into U.S. retail channels in the third quarter of 2021. Net sales of the 81 mg dose represented approximately 68% of total net sales for the full year 2021. Revenue in the prior year period was attributable to work performed under an award of a federal grant from the National Institutes of Health, which came to an end in the second quarter of 2020.

Gross margin of 41% for the full year 2021 includes outsourced manufacturing and packaging costs combined with costs related to shipping, quality assurance and royalty payments. Gross profit from the VAZALORE 325 mg dose is lower due to proportionally higher raw materials and smaller batch sizes although with a list price equal to the 81 mg 30 count bottle.

Total operating expenses were $44.2 million for full year 2021, compared to operating expenses of $13.5 million for the prior year period, reflecting increased promotional activities and expenses associated with the commercial launch of VAZALORE during the third quarter of 2021.

Net loss attributable to common stockholders for the year ended December 31, 2021 was $48.6 million or ($2.06) per diluted share compared to a net loss of $16.9 million, or ($1.74) per diluted share for 2020.

Adjusted non-GAAP net loss per diluted share was ($1.72) for full year 2021, compared to an adjusted net loss of ($1.42) per diluted share in the prior year period.

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.
