expenses in 2021 compared to 2020 was primarily attributable to $7.4 million related to the acquisition of certain assets from Neumedicines Inc., which closed in the third quarter of 2021, coupled with costs for key clinical trials in 2021, including costs incurred in preparation for a Phase 3 study evaluating selinexor in combination with pomalidomide in patients with relapsed or refractory multiple myeloma.
Selling, general and administrative (SG&A) expenses: SG&A expenses for the fourth quarter of 2021 were $34.6 million, compared to $33.9 million for the fourth quarter of 2020.

The increase in SG&A expenses compared to the prior year was due primarily to increased personnel costs.
Interest expense: Interest expense for the fourth quarter of 2021 was $7.9 million, compared to $7.1 million for the fourth quarter of 2020. Interest expense for the year ended December 31, 2021 was $26.0 million, compared to $27.1 million for the year ended December 31, 2020. The decrease in interest expense year over year was primarily attributable to a $7.3 million decrease in non-cash interest expense related to Karyopharm’s 3.00% senior convertible notes due 2025, as a result of the January 1, 2021 adoption of ASU No. 2020-06, Debt—Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity’s Own Equity, partially offset by a $6.2 million increase in interest expense related to the deferred royalty obligation following Karyopharm’s June 2021 amendment of its Revenue Interest Agreement with HealthCare Royalty Management, LLC.
Net income (loss): Karyopharm reported net income of $38.7 million, or $0.51 per basic share and $0.46 per diluted share, for the fourth quarter of 2021, compared to a net loss of $43.4 million, or $0.59 per basic and diluted share, for the fourth quarter of 2020. Net income (loss) includes non-cash stock-based compensation expense of $6.9 million and $6.3 million for the fourth quarters of 2021 and 2020, respectively. Karyopharm reported a net loss of $124.1 million, or $1.65 per basic and diluted share, for the year ended December 31, 2021, compared to a net loss of $196.3 million, or $2.72 per basic and diluted share, for the year ended December 31, 2020.

2022 Financial Outlook
Based on its current operating plans, Karyopharm expects the following for full year 2022:
| • | | XPOVIO net product revenue to be in the range of $135 million to $145 million. |
| • | | Non-GAAP R&D and SG&A expenses, excluding stock-based compensation expense, for the year ending December 31, 2022, to be in the range of $265 million to $280 million. Karyopharm has not reconciled the full year 2022 outlook for non-GAAP R&D and SG&A expenses to full year 2022 outlook for GAAP R&D and SG&A expenses because Karyopharm cannot reliably predict without unreasonable efforts the timing or amount of the factors that substantially contribute to the projection of stock compensation expense, which is excluded from the full year 2022 outlook for non-GAAP R&D and SG&A expenses. |
| • | | The Company expects that its existing cash, cash equivalents and investments, and the revenue it expects to generate from XPOVIO product sales, as well as revenue generated from its license agreements, will be sufficient to fund its planned operations into early 2024. |
