Insights

Karyopharm's Q2 2024 results show mixed performance. Total revenue increased to $42.8 million from $37.6 million in Q2 2023, driven by higher license and other revenue. However, U.S. XPOVIO net product revenue slightly decreased to $28.0 million from $28.5 million year-over-year.

The company's financial outlook has improved, with raised guidance for total revenue ($145.0-$160.0 million) and U.S. XPOVIO net product revenue ($105.0-$120.0 million). Notably, R&D and SG&A expense guidance was lowered to $250.0-$265.0 million, indicating better cost management.

The debt refinancing has strengthened Karyopharm's balance sheet, extending most debt maturities to 2028 and 2029. This provides financial stability beyond expected data readouts from three Phase 3 trials. However, investors should note the 23.6% decrease in cash position since December 31, 2023.

The clinical updates for Karyopharm's lead drug, selinexor, are encouraging. In endometrial cancer, the SIENDO study showed impressive median PFS of 28.4 months in TP53 wild-type patients and 39.5 months in the pMMR TP53 wild-type subgroup. These results suggest potential efficacy in specific patient populations.

In multiple myeloma, the SPd regimen demonstrated a median PFS of 18.4 months with a manageable safety profile. This data supports the ongoing Phase 3 trial, although enrollment challenges have led to study design amendments.

The preclinical data in myelofibrosis is intriguing, showing selinexor's potential to target multiple oncogenic pathways beyond JAK/STAT. This could provide a rationale for both monotherapy and combination approaches. However, it's important to note that these are early-stage findings and need validation in clinical trials.

Karyopharm faces a competitive landscape in multiple myeloma, evidenced by the >10% growth in the community setting but consistent demand in the academic setting. The company's strategy to position XPOVIO around T-cell therapies in later lines could be a differentiator.

The global expansion of XPOVIO is progressing well, with favorable reimbursement decisions in the UK and South Korea and additional approvals in China and other markets. This international growth could become a significant revenue driver in the future.

However, challenges in clinical trial enrollment for the XPORT-MM-031 study in multiple myeloma highlight the intensifying competition in this space. The company's decision to amend the trial design reflects the need for adaptability in a rapidly evolving market.

The Rare Pediatric Disease and Orphan Drug Designations for KPT-9274 in rare pediatric cancers open up new potential markets, but the company's decision to seek partnerships for this program suggests a focus on core assets.

NEWTON, Mass., Aug. 6, 2024 /PRNewswire/ -- Karyopharm Therapeutics Inc. (Nasdaq: KPTI), a commercial-stage pharmaceutical company pioneering novel cancer therapies, today reported financial results for the quarter ended June 30, 2024, and highlighted select corporate milestones and progress on its key clinical development programs.

"We are pleased with the strength of our commercial performance with consecutive quarter-over-quarter growth in the highly competitive multiple myeloma marketplace and look forward to leveraging the foundation that we have built in this indication to serve additional patients. Looking ahead with our improved capital structure following our debt refinancing and disciplined expense management, we are strongly positioned for our next stage of growth, to redefine the standard of care for patients with myelofibrosis and endometrial cancer, driven by selinexor's growing body of compelling clinical and preclinical data in these indications," said Richard Paulson, President and Chief Executive Officer of Karyopharm.

Second Quarter 2024 and Recent Highlights

XPOVIO Commercial Performance 

  • Achieved U.S. net product revenue of $28.0 million for the second quarter of 2024, compared to $26.0 million for the first quarter of 2024 and $28.5 million for the second quarter of 2023.

  • XPOVIO net product revenue was supported by quarter-over-quarter growth in both new patient starts and refills.

  • Continued quarter-over-quarter growth with > 10% growth in the community setting, which represents ~60% of overall net product revenues. In the academic setting, demand for XPOVIO was consistent quarter-over-quarter amidst ongoing competitive pressures, driven by the expanding use of XPOVIO immediately preceding and following T-cell therapies in later lines. The vast majority of XPOVIO new patient mix continues to be in the second to fourth lines of therapy.

  • Continued global momentum in the second quarter of 2024 with favorable reimbursement decisions in the United Kingdom and South Korea, and additional regulatory approvals in relapsed/refractory (R/R) DLBCL in mainland China and R/R multiple myeloma in multiple international markets.

Research and Development (R&D) Highlights

Myelofibrosis

  • Pre-clinical data were presented on the mechanism of action for XPO1 inhibition in myelofibrosis targeting multiple oncogenic pathways beyond JAK/STAT, including inhibition of NF-κB-driven proinflammatory cytokines and p53-mediated cell cycle regulation, at the June 2024 European Hematology Association meeting. These data suggest that XPO1 may be fundamental in myelofibrosis, providing the mechanistic rationale for both monotherapy as well as additive, if not synergistic, activity in combination with ruxolitinib, which we believe further supports the promising clinical results, including durable spleen volume reduction and symptom improvement, observed to date from the Phase 1 trial.

  • Pivotal SENTRY Phase 3 trial of selinexor in combination with ruxolitinib in JAK-naive myelofibrosis continues to enroll with strong momentum, supported by high interest from investigators and minimal competition from other therapies in the JAK-naïve setting; expected top-line data readout on track for 2H 2025.

Endometrial Cancer

  • Long-term follow-up data from a pre-specified exploratory subgroup analysis of patients with advanced or recurrent TP53 wild-type endometrial cancer from the SIENDO study (NCT03555422) were presented at "ASCO Plenary Series: Rapid Abstract Updates" oral session at the ASCO Annual Meeting in June 2024.

  • In the exploratory subgroup analysis from the Phase 3 SIENDO Study, 113 patients with TP53 wild-type advanced/recurrent endometrial cancer were randomized to receive selinexor (n=77) vs placebo (n=36) as maintenance therapy after 1L platinum-based chemotherapy. As of the April 1, 2024 data cut-off date, and a median duration of follow-up of 36.8 months, selinexor-treated patients had a median PFS of 28.4 months compared to 5.2 months for patients receiving placebo. In selinexor-treated patients with TP53 wild-type/pMMR and TP53 wild-type/dMMR endometrial cancer, the median PFS was 39.5 months and 13.1 months compared to 4.9 months and 3.7 months in those treated with placebo, respectively. Although immature, overall survival (OS) in the TP53 wild-type subgroup was promising, with a hazard ratio of 0.65; median OS for selinexor has not been reached as of the data cut-off date. No new safety signals were identified as of the data cut-off date of April 1, 2024. The most common treatment-emergent adverse events in selinexor treated TP53 wild-type patients were nausea (90%), vomiting (60%) and diarrhea (45%), the majority of which were grades 1-2.

  • The updated SIENDO analysis also highlighted findings from an exploratory quality-adjusted time without symptoms or toxicity analysis (Q-TWiST) used to assess quality and toxicity-adjusted PFS. The findings showed the restricted mean Q-TWiST for selinexor to be 26 months compared to 15 months for placebo, resulting in a difference of nearly 11 months.

  • Pivotal XPORT-EC-042 Phase 3 trial in TP53 wild-type endometrial cancer is now expected to read-out top-line data in early 2026, primarily due to higher-than-expected screen failure rates.

Multiple Myeloma

  • Updated clinical data on SPd (selinexor in combination with pomalidomide and dexamethasone) regimen from STOMP and MM-028 trials were published in the Frontiers of Oncology Journal in May 2024. Both the Phase 1b/2 Selinexor and Backbone Treatments of Myeloma Patients (STOMP) trial (NCT02343042) and the Phase 2b XPORT-MM-028 (NCT04414475) trials are evaluating multiple selinexor combinations, including SPd, in patients with relapsed or refractory multiple myeloma (RRMM). The updated results for SPd 40 mg from these studies showed a median PFS of 18.4 months and a manageable safety profile with no new safety signals.

  • Pivotal XPORT-MM-031 (EMN29) Phase 3 trial, an oral combination of selinexor 40 mg, pomalidomide and dexamethasone in patients with previously treated multiple myeloma, is enrolling patients at a lower rate than expected in an increasingly global competitive clinical trial environment targeting a similar patient population. Given this evolving environment and the positive SPd 40 mg PFS data published from the STOMP and MM-028 trials, Karyopharm intends to work with the trial's sponsor, the European Myeloma Network, to amend certain aspects of the design for this trial, including a reduction in the number of patients that are targeted for enrollment, and the statistical plan. With these updates, Karyopharm expects top-line data readout in 1H 2025; there remains a potential to seek regulatory approval pending the outcome of the study results.

KPT-9274 (Padnarsertib)

  • KPT-9274, a first-in-class, oral small molecule and a dual inhibitor of PAK4 and NAMPT that was discovered at Karyopharm, was granted two Rare Pediatric Disease Designations (RPDD) by the U.S. Food and Drug Administration (FDA) for the treatment of Rhabdomyosarcoma (RMS) and for the treatment of Ewing sarcoma (EWS) in June 2024. The FDA further granted KPT-9274 two Orphan Drug Designations in July 2024 for the treatment of soft tissue sarcoma, which includes RMS, and for the treatment of EWS. RMS and EWS are rare cancers of the bone or soft tissue, primarily diagnosed in pediatric patients, with poor survival outcomes and high unmet need for new therapies. KPT-9274 showed tumor regressions and decreased metastatic properties in pediatric RMS and EWS pre-clinical models. Karyopharm is evaluating out-licensing and/or partnership opportunities for further advancement of this program.

Financing Transactions and 2024 Financial Outlook

  • In May 2024, the Company completed certain financing transactions which extended the vast majority of its debt maturities into 2028 and 2029 and amended its royalty agreement with HealthCare Royalty, further strengthening its balance sheet.

Based on its current operating plans, Karyopharm has updated its guidance for full year 2024 as follows:

  • Total revenue to be in the range of $145.0 million to $160.0 million as compared to initial guidance of $140.0 million to $160.0 million. Total revenue consists of U.S. XPOVIO net product revenue and license, royalty and milestone revenue earned from partners.

  • U.S. XPOVIO net product revenue to be in the range of $105.0 million to $120.0 million as compared to initial guidance of $100.0 million to $120.0 million.

  • R&D and selling, general and administrative (SG&A) expenses to be in the range of $250.0 million to $265.0 million, which includes approximately $20.0 million estimated non-cash stock-based compensation expense, as compared to initial guidance of $260.0 million to $280.0 million including $20.0 million to $25.0 million of estimated non-cash stock-based compensation expense.

  • The Company expects that its existing cash, cash equivalents and investments, and the revenue it expects to generate from XPOVIO net product sales, as well as revenue generated from its license agreements, will be sufficient to fund its planned operations into the first quarter of 20261 aided by ongoing disciplined expense management and initiated cost saving measures.

Net product revenue: Net product revenue for the second quarter of 2024 was $28.0 million, compared to $28.5 million for the second quarter of 2023.

License and other revenue: License and other revenue for the second quarter of 2024 was $14.8 million, compared to $9.1 million for the second quarter of 2023. The increase was primarily due to $4.0 million of milestone-related revenue recognized from Menarini in 2024 and a $2.3 million increase in revenue for the reimbursement of development-related expenses from Menarini due to an increase in the corresponding expenses.

Cost of sales: Cost of sales for the second quarter of 2024 was $1.5 million, compared to $1.2 million for the second quarter of 2023. Cost of sales reflects the costs of XPOVIO units sold and the costs of products sold to our partners.

R&D expenses: R&D expenses for the second quarter of 2024 were $38.4 million, compared to $31.5 million for the second quarter of 2023. The increase was primarily due to an increase in clinical trial and related costs, related mainly to increased activity in our ongoing pivotal Phase 3 trials in myelofibrosis and multiple myeloma, including increased purchases of comparator drugs.

SG&A expenses: SG&A expenses for the second quarter of 2024 were $31.1 million, compared to $34.5 million for the second quarter of 2023. The decrease was primarily due to our ongoing cost reduction initiatives and lower headcount.

Interest income: Interest income for the second quarter of 2024 was $1.9 million, compared to $2.8 million for the second quarter of 2023.

Interest expense: Interest expense for the second quarter of 2024 was $8.9 million, compared to $5.8 million for the second quarter of 2023. The increase in interest expense was due to the Company's new term loan and new secured convertible senior notes.

Gain on extinguishment of debt and other income: The Company recognized a non-cash gain on extinguishment of debt of $44.7 million and other income of $14.3 million during the second quarter of 2024, which related to the refinancing transactions that were completed during the second quarter of 2024. 

Net income (loss): Karyopharm reported net income of $23.8 million, or $0.15 income per basic share and $0.20 loss per diluted share, for the second quarter of 2024, compared to a net loss of $32.6 million, or $0.29 loss per basic and diluted share, for the second quarter of 2023.

This press release contains forward-looking statements within the meaning of The Private Securities Litigation Reform Act of 1995. Such forward-looking statements include those regarding Karyopharm's guidance on its 2024 total revenue, 2024 U.S. net product revenue and 2024 R&D and SG&A expenses; Karyopharm's expected cash runway; expectations with respect to commercialization efforts; the ability of selinexor to treat patients with multiple myeloma, endometrial cancer, myelofibrosis, diffuse large B-cell lymphoma, and other diseases; and expectations with respect to the clinical development plans and potential regulatory submissions of selinexor. Such statements are subject to numerous important factors, risks and uncertainties, many of which are beyond Karyopharm's control, that may cause actual events or results to differ materially from Karyopharm's current expectations. For example, there can be no guarantee that Karyopharm will successfully commercialize XPOVIO or that any of Karyopharm's drug candidates, including selinexor, will successfully complete necessary clinical development phases or that development of any of Karyopharm's drug candidates will continue. Further, there can be no guarantee that any positive developments in the development or commercialization of Karyopharm's drug candidate portfolio will result in stock price appreciation. Management's expectations and, therefore, any forward-looking statements in this press release could also be affected by risks and uncertainties relating to a number of other factors, including the following: the adoption of XPOVIO in the commercial marketplace, the timing and costs involved in commercializing XPOVIO or any of Karyopharm's drug candidates that receive regulatory approval; the ability to obtain and retain regulatory approval of XPOVIO or any of Karyopharm's drug candidates that receive regulatory approval; Karyopharm's results of clinical trials and preclinical trials, including subsequent analysis of existing data and new data received from ongoing and future trials; the content and timing of decisions made by the U.S. Food and Drug Administration and other regulatory authorities, investigational review boards at clinical trial sites and publication review bodies, including with respect to the need for additional clinical trials; the ability of Karyopharm or its third party collaborators or successors in interest to fully perform their respective obligations under the applicable agreement and the potential future financial implications of such agreement; Karyopharm's ability to enroll patients in its clinical trials; unplanned cash requirements and expenditures; development or regulatory approval of drug candidates by Karyopharm's competitors for products or product candidates in which Karyopharm is currently commercializing or developing; the direct or indirect impact of the COVID-19 pandemic or any future pandemic on Karyopharm's business, results of operations and financial condition; and Karyopharm's ability to obtain, maintain and enforce patent and other intellectual property protection for any of its products or product candidates. These and other risks are described under the caption "Risk Factors" in Karyopharm's Quarterly Report on Form 10-Q for the quarter ended March 31, 2024, which was filed with the Securities and Exchange Commission (SEC) on May 8, 2024, and in other filings that Karyopharm may make with the SEC in the future. Any forward-looking statements contained in this press release speak only as of the date hereof, and, except as required by law, Karyopharm expressly disclaims any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.
