Current report

We expect net product revenue to remain relatively consistent in the fourth quarter of 2024 as compared to the third quarter of 2024.

Current report

License and other revenue for the nine months ended September 30, 2024 increased by $5.8 million as compared to the nine months ended September 30, 2023 primarily due to $10.0 million of milestone revenue recognized from Menarini during the nine months ended September 30, 2024, partially offset by a decrease of $3.5 million of license-related revenue from Menarini.

Current report

We expect license and other revenue to decrease in the fourth quarter of 2024 as compared to the third quarter of 2024 due to the maximum reimbursement revenue from Menarini already having been recognized, coupled with lower milestone revenue expected in the fourth quarter of 2024 compared to the third quarter of 2024.

Current report

We expect our research and development expenses to slightly decrease in the fourth quarter of 2024 as compared to the third quarter of 2024 primarily due to the reduced scope of our Phase 3 trial in multiple myeloma, as well as reduced headcount due to our ongoing cost reduction initiatives, partially offset by an expected increase in expenses related to our Phase 3 trial in myelofibrosis.

Current report

Selling, general and administrative expenses for the three months ended September 30, 2024 decreased by $3.2 million as compared to the three months ended September 30, 2023. The decrease in personnel costs of $2.4 million was primarily due to a reduction in headcount and contractors.

Current report

We anticipate that we will continue to incur significant operating losses in the foreseeable future. Based on our current business plan and current capital resources, combined with the uncertainty regarding the availability of additional funding, we have concluded that there is substantial doubt regarding our ability to continue as a going concern within one year after the date the accompanying condensed consolidated financial statements are issued. We expect that our cash, cash equivalents and investments as of September 30, 2024 will be sufficient to fund our current operating plans and debt obligation requirements into the fourth quarter of 2025. See “Liquidity and Capital Resources – Funding Requirements” below and Note 1 “Nature of Business” to the condensed consolidated financial statements included under Part I, Item I of this Quarterly Report on Form 10-Q for a further discussion of our liquidity and the conditions that raise substantial doubt regarding our ability to continue as a going concern.

To date, our only source of product revenue has been from the U.S. sales of XPOVIO. Net product revenue for the three and six months ended June 30, 2024 decreased as compared to the three and six months ended June 30, 2023, primarily due to decreased demand as a result of increasing competition and higher gross-to-net driven by increased Medicare/Medicaid rebates and 340B discounts.

Research and development expenses for the three months ended June 30, 2024 increased by $6.9 million as compared to the three months ended June 30, 2023. The $7.4 million increase in clinical trial and related costs was primarily due to increased activity in our ongoing pivotal Phase 3 trials in myelofibrosis and multiple myeloma, including increased purchases of comparator drugs. These increases were partially offset by decreases of clinical trial and related costs in other programs, primarily KPT-1200, our IL-12 compound that we sold to Libo Pharma Corp. in December 2023.

Current wording

Research and development expenses for the three months ended September 30, 2024 increased by $0.6 million as compared to the three months ended September 30, 2023 primarily due to increased activity in our ongoing pivotal Phase 3 trial in myelofibrosis, partially offset by decreases in clinical trial and related costs in other programs.

The $12.7 million increase in clinical trial and related costs was primarily due to increased activity in each of our three ongoing pivotal Phase 3 trials, including increased purchases of comparator drugs. These increases were partially offset by decreases of clinical trial and related costs in other programs, primarily KPT-1200, our IL-12 compound, and eltanexor. The decrease in personnel costs of $3.6 million was primarily due to a reduction in headcount and contractors for the six months ended June 30, 2024 as compared to the six months ended June 30, 2023.

Current wording

We expect our selling, general and administrative expenses to remain relatively consistent in the fourth quarter of 2024 as compared to the third quarter of 2024.

Previous wording

The increases for the three and six month periods were primarily due to a $44.7 million gain on extinguishment of debt from the Refinancing Transactions and a $14.3 million gain from the remeasurement of embedded derivatives and liability classified common stock warrants, both of which are non-cash items. These gains were partially offset by an increase in interest expense due to the new term loan and new secured convertible senior notes.

Current wording

Other income (expense), net for the nine months ended September 30, 2024 increased by $52.0 million as compared to the nine months ended September 30, 2023, primarily due to a $44.7 million gain on extinguishment of debt from the Refinancing Transactions and a $18.3 million gain from the remeasurement of embedded derivatives and liability classified common stock warrants, both of which are non-cash items. These gains were partially offset by an increase in interest expense related to the new term loan and new secured convertible senior notes.

Previous wording

We expect Other income (expense), net to decrease in the second half of 2024 as compared to the first half of 2024, as the $44.7 million gain on extinguishment of debt is a non-recurring gain. This will be partially offset by an increase in interest expense on the new term loan and new secured convertible senior notes. The future impact from remeasurements of the embedded derivatives and liability classified common stock warrants will depend on a variety of factors, including movements in our stock price.

Current wording

We expect Other income (expense), net to remain relatively consistent in the fourth quarter of 2024 as compared to the third quarter of 2024, however the future impact from remeasurements of the embedded derivatives and liability classified common stock warrants will depend on a variety of factors, including movements in our stock price.

We currently expect that cash, cash equivalents and investments at June 30, 2024 will be sufficient to fund our current operating plans and capital expenditure requirements for at least twelve months from the date of issuance of the financial statements contained in this Quarterly Report on Form 10-Q while we continue to commercialize XPOVIO in the U.S. and continue the clinical trials of our product candidates. Our future long-term capital requirements will depend on many factors, as described more fully in the risk factor entitled “We will need additional funding to achieve our business objectives. If we are unable to raise capital when needed or on acceptable terms, we would be forced to delay, reduce or eliminate our research and development programs and/or commercialization efforts,” under the heading“Risk Factors” in this Quarterly Report on Form 10-Q.

Current wording

Based on our current business plan and current capital resources, combined with the uncertainty regarding the availability of additional funding, we have concluded that there is substantial doubt regarding our ability to continue as a going concern within one year after the date the condensed consolidated financial statements are issued. See Note 1 “Nature of Business” to the condensed consolidated financial statements included under Part I, Item I of this Quarterly Report on Form 10-Q for a further discussion of the conditions that raise substantial doubt regarding our ability to continue as a going concern. We currently expect that cash, cash equivalents and investments as of September 30, 2024 will be sufficient to fund our current operating plans and debt obligation requirements into the fourth quarter of 2025 while we continue to commercialize XPOVIO in the U.S. and continue the clinical trials of our product candidates. Our future long-term capital requirements will depend on many factors, as described more fully in the risk factor entitled “We will need additional funding to achieve our business objectives. If we are unable to raise capital when needed or on acceptable terms, we would be forced to delay, reduce or eliminate our research and development programs and/or commercialization efforts,” under the heading“Risk Factors” in this Quarterly Report on Form 10-Q.

Current report — wording carried from elsewhere

Net product revenue for the nine months ended September 30, 2024 decreased as compared to the nine months ended September 30, 2023, primarily due to decreased demand as a result of increasing competition and higher gross-to-net discounts driven by increased Medicare rebates and 340B discounts.

Current report — wording carried from elsewhere

Other income (expense), net for the three months ended September 30, 2024 decreased by $2.5 million, as compared to the three months ended September 30, 2023, primarily due to a $5.3 million increase in interest expense related to the new term loan and new secured convertible senior notes, partially offset by a gain of $4.0 million recognized during the three months ended September 30, 2024 from the remeasurement of embedded derivatives and liability classified common stock warrants, both of which are non-cash items.
