Second Quarter 2022 Financial Results

Total revenue was $4.1 million in second quarter 2022 compared to $2.1 million for the same period in 2021. The increase was primarily driven by $1.2 million in higher Zokinvy net product sales and $0.8 million from an upfront payment the Company received related to its exclusive partnership with AnGes, Inc. to seek regulatory approval and commercialization of Zokinvy in Japan.

Cost of sales was $0.2 million for second quarter 2022 as compared to $0.3 million for the same period in 2021. The decrease was primarily driven by product manufacturing related costs, including product testing.

Research and Development expenses were $17.0 million for second quarter 2022, as compared to $14.3 million for the same period in 2021. The increase is primarily driven by personnel related costs, including stock-based compensation, from additional headcount, and outside services, including consulting and advisory services.

Selling, General and Administrative expenses were $7.0 million for second quarter 2022, as compared to $5.9 million for the same period in 2021. The increase was primarily due to outside services, including consulting and advisory services, and an increase in headcount related expenses and other operating related expenses.

Total operating expenses include non-cash expenses of $4.1 million for second quarter 2022, as compared to $2.7 million for the same period in 2021.
