In addition, during the second quarter of 2022, the company incurred a $10.0 million in-process R&D (IPR&D) charge associated with an upfront payment related to the execution of a licensing arrangement with iVeena Delivery Systems, Inc., compared to a $5.0 million IPR&D charge incurred in the second quarter of 2021 associated with an upfront payment related to the execution of an amended licensing arrangement with Intratus, Inc. These charges were included in both GAAP and non-GAAP operating expenses, which is a change versus the company’s previous methodology where similar IPR&D transactions were excluded for non-GAAP disclosure and reporting purposes. This change is the result of the U.S. Securities and Exchange Commission’s most recent industry correspondence on this matter.
Loss from operations in the second quarter of 2022 was $36.8 million, compared to operating loss of $14.2 million in the second quarter of 2021. Non-GAAP loss from operations in the second quarter of 2022 was $30.4 million, compared to non-GAAP operating loss of $6.8 million in the second quarter of 2021. Included in the non-GAAP loss from operations figures are IPR&D charges of $10.0 million and $5.0 million in the second quarter of 2022 and 2021, respectively.
Net loss in the second quarter of 2022 was $45.5 million, or ($0.96) per diluted share, compared to a net loss of $17.5 million, or ($0.38) per diluted share, in the second quarter of 2021. Non-GAAP net loss in the second quarter of 2022 was $39.1 million, or ($0.83) per diluted share, compared to non-GAAP net loss of $10.1 million, or ($0.22) per diluted share, in the second quarter of 2021. Included in the non-GAAP net loss figures are IPR&D charges of $10.0 million and $5.0 million in the second quarter of 2022 and 2021, respectively, which caused the non-GAAP loss per diluted share to have an additional loss of ($0.21) and ($0.11) in each of these respective periods.
The company ended the second quarter of 2022 with approximately $400 million in cash and cash equivalents, short-term investments and restricted cash.
