Karyopharm Therapeutics Inc. (KPTI) - Canvas Business Model: Key Partnerships

You're looking at how Karyopharm Therapeutics Inc. spreads its commercial and clinical load through key alliances, which is crucial for a company with a focused product like XPOVIO® (selinexor).

Menarini Group handles commercialization for selinexor in Europe and other ex-U.S. territories, where it is branded as NEXPOVIO®. Karyopharm Therapeutics Inc. has received regulatory approvals in various indications across 50 ex-U.S. territories and countries, including Europe and the United Kingdom. This partnership directly translates into revenue growth; royalty revenue from international partners, primarily the Menarini Group, was $1.5 million in the third quarter of 2025, up from $0.9 million in the third quarter of 2024. For the second quarter of 2025, royalty revenue increased 28% year-over-year to $1.6 million.

Karyopharm Therapeutics Inc. also relies on other international partners for market access, including Antengene, Neopharm, and FORUS. Antengene's agreement covers the development and commercialization of XPOVIO® and other compounds in the Asia Pacific region, including mainland China, South Korea, and ASEAN markets. The growth in royalty revenue in Q2 2025 was attributed to Menarini, Antengene, and other international partners.

The collaboration with the European Myeloma Network (EMN) is central to Karyopharm Therapeutics Inc.'s clinical development in multiple myeloma. This partnership is executing the Phase 3 XPORT-MM-031 trial (EMN29; NCT05028348), which evaluates the all-oral combination of selinexor 40 mg, pomalidomide, and dexamethasone (SPd40). Enrollment for this trial was completed in the fourth quarter of 2024, involving approximately 117 to 120 patients. The study was initially expected to recruit about 280 patients. Karyopharm Therapeutics Inc. anticipates reporting top-line data from this event-driven trial in the first half of 2026.

Karyopharm Therapeutics Inc. uses Clinical Research Organizations (CROs) to manage the execution of its global trials. This outsourcing helps manage the complexity of studies like the Phase 3 SENTRY trial in myelofibrosis, which completed enrollment with 353 patients in early September 2025.

Here's a quick look at the key partnership metrics we have for late 2025:

You should note the following about the structure of these external relationships:

• The Menarini Group agreement is tied to regulatory approvals in territories like Europe and the UK.
• Antengene's rights cover four oral novel drugs and drug candidates in the Asia Pacific region.
• The XPORT-MM-031 trial uses selinexor 40 mg in combination with pomalidomide and dexamethasone.
• Karyopharm Therapeutics Inc. is actively managing its liquidity, expecting current revenue streams, including partner royalties, to fund operations into the second quarter of 2026.

Karyopharm Therapeutics Inc. (KPTI) - Canvas Business Model: Key Activities

You're looking at the core actions Karyopharm Therapeutics Inc. (KPTI) is driving right now to keep the business moving forward, especially as they manage commercial performance alongside late-stage clinical execution. Here's the quick math on what they are actively doing as of late 2025.

U.S. commercialization and sales of XPOVIO (selinexor)

The primary commercial engine is the ongoing sale of XPOVIO in the U.S. market. For the third quarter ending September 30, 2025, Karyopharm Therapeutics Inc. reported U.S. XPOVIO net product revenue hit $32.0 million. That's an 8.5% increase compared to the third quarter of 2024. Honestly, the community setting is still the backbone of this revenue stream, driving approximately 60% of the total net product revenue in Q3 2025. The company is sticking to its full-year 2025 forecast, expecting U.S. XPOVIO net product revenue to land between $110 million and $120 million, contributing to a total expected revenue range of $140 million to $155 million for the year.

Executing pivotal Phase 3 SENTRY trial in myelofibrosis

A major activity has been pushing the pivotal Phase 3 SENTRY trial over the finish line. Karyopharm Therapeutics Inc. announced that enrollment for the SENTRY trial, which evaluates selinexor in combination with ruxolitinib for JAKi-naïve myelofibrosis patients, was completed in early September 2025. This trial targeted 350 patients, and they successfully enrolled 353 patients. The next critical milestone for this activity is the reporting of top-line data, which Karyopharm Therapeutics Inc. has scheduled for March 2026. This trial uses two co-primary endpoints:

• Spleen volume response rate greater than or equal to 35% (SVR35) at week 24.
• The average change in absolute total symptom score (Abs-TSS) over 24 weeks relative to baseline.

Research and development of novel Selective Inhibitor of Nuclear Export (SINE) compounds

Research and development (R&D) spending reflects the ongoing pipeline work, though Karyopharm Therapeutics Inc. has been actively managing costs. For the third quarter of 2025, R&D expenses were $30.5 million. This is down from $38.4 million in Q3 2024, reflecting lower clinical trial costs for the multiple myeloma Phase 3 trial and reduced personnel expenses. Looking at the full year 2025, the company has lowered its combined guidance for R&D and selling, general and administrative (SG&A) expenses to a range of $235 million to $245 million. This disciplined approach is intended to extend liquidity.

Managing global regulatory submissions and approvals for new indications

Karyopharm Therapeutics Inc. is managing the expansion of selinexor globally through its partners. XPOVIO has already received regulatory approvals in various indications across 50 ex-U.S. territories and countries, including Europe and China (as NEXPOVIO). This global reach directly translates into revenue-generating activities. For instance, royalty revenue increased to $1.5 million in the third quarter of 2025, up from $0.9 million in the third quarter of 2024, showing that expanded patient access overseas is a key operational focus.

Here is a snapshot of the key financial and operational metrics tied to these activities as of the third quarter of 2025:

Karyopharm Therapeutics Inc. (KPTI) - Canvas Business Model: Key Resources

You're looking at the core assets Karyopharm Therapeutics Inc. is relying on as it pushes toward key clinical readouts in early 2026. These aren't just line items; they represent the product, the protection, the people, and the purse that fund operations.

XPOVIO (selinexor), a first-in-class oral XPO1 inhibitor

The commercial engine is XPOVIO, Karyopharm Therapeutics Inc.'s lead asset. Its performance dictates the near-term financial health. The community setting remains the primary driver of sales volume, which is a key operational insight for resource allocation.

Here's the quick math on the product's recent performance based on the third quarter of 2025 results:

Core intellectual property and patents covering SINE technology

The foundation of Karyopharm Therapeutics Inc.'s value rests on its Selective Inhibitor of Nuclear Export (SINE) technology. The protection around selinexor is critical for maintaining market exclusivity and justifying future investment in the pipeline.

• Composition-of-matter patent (US8999996) for selinexor is set to expire in 2032 absent term extensions.
• Patents covering polymorphs of selinexor are noted to expire in August 2035.
• Newly issued patents related to the core technology are also set to expire in August 2035.

Specialized U.S. commercial and medical affairs organization

Karyopharm Therapeutics Inc. maintains a commercial footprint focused on maximizing the value of XPOVIO, particularly in the multiple myeloma space where it has built its initial foundation. This organization is the direct interface for driving the $110 million to $120 million in expected U.S. XPOVIO revenue for the full year 2025.

The organization's structure is being managed under tighter spending controls, with full-year 2025 R&D and SG&A expenses guided between $235 million and $245 million.

Cash and equivalents, with runway into the second quarter of 2026

Liquidity management has been a major focus, especially following the October 2025 financing transactions. The company secured additional capital to bridge operations through a critical clinical data readout. What this estimate hides is the burn rate needed to achieve that runway.

Karyopharm Therapeutics Inc. (KPTI) - Canvas Business Model: Value Propositions

You're looking at the core reasons why prescribers and patients choose Karyopharm Therapeutics Inc.'s XPOVIO (selinexor) over other options, especially as the company pushes into new indications. The value proposition centers on its unique mechanism and its oral convenience.

Oral, First-in-Class Treatment for Multiple Myeloma Patients with Limited Options

XPOVIO is Karyopharm Therapeutics Inc.'s first-in-class, oral exportin 1 (XPO1) inhibitor. For multiple myeloma (MM) patients, this represents a crucial option when standard therapies fail. The drug has shown activity in what's called 'penta-refractory' MM, meaning patients who are refractory to the 5 most active anti-MM agents currently in use. This positions XPOVIO as a vital late-line therapy.

The commercial success reflects this value, with U.S. XPOVIO net product revenue reaching $32.0 Million in the third quarter of 2025. This is up from $29.5 Million in the third quarter of 2024, showing continued adoption. The community setting is a major driver, accounting for approximately 60% of overall net product revenue as of Q3 2025.

Here's a quick look at the financial context supporting this value:

Potential to Redefine Standard-of-Care in Frontline Myelofibrosis

Karyopharm Therapeutics Inc. is actively pursuing the myelofibrosis (MF) market, where selinexor, in combination with ruxolitinib, is being tested to potentially establish a new standard-of-care. The Phase 3 SENTRY trial, which completed enrollment as of late 2025, is evaluating this all-oral combination in JAK inhibitor-naïve MF patients. Top-line data from this pivotal trial is anticipated in March 2026. The strategy here isn't to compete directly with ruxolitinib, the current go-to, but to serve as an addition, creating an all-oral regimen.

The company is preparing for a potential launch, leveraging its existing commercialization capabilities from the MM market. This potential indication represents a significant expansion of the value proposition beyond established uses.

Addressing Nuclear Export Dysregulation, a Fundamental Mechanism of Cancer

The core scientific value of XPOVIO lies in its mechanism. Karyopharm Therapeutics Inc. has been an industry leader in compounds targeting nuclear export dysregulation, which is a fundamental mechanism of oncogenesis. XPOVIO, as a Selective Inhibitor of Nuclear Export (SINE) compound, selectively binds to and inhibits the nuclear export protein XPO1.

This inhibition forces the nuclear retention and functional activation of critical tumor suppressor proteins, while simultaneously limiting the translation of oncoproteins. This action leads to growth arrest and apoptosis in malignant cells. The overexpression of XPO1 is noted in various malignancies, correlating with poor prognosis, so blocking it offers a distinct therapeutic strategy.

• Inhibition of XPO1 causes nuclear retention of tumor suppressor proteins.
• This mechanism leads to selective apoptosis of cancer cells.
• Normal cells, in contrast, typically undergo only transient cell cycle arrest.
• XPO1 overexpression is identified in multiple malignancies.

Convenience of an All-Oral Combination Therapy (e.g., in Multiple Myeloma)

The oral formulation of XPOVIO provides significant convenience for patients, especially when used in combination regimens. In multiple myeloma, for instance, XPOVIO is used in combination with dexamethasone in heavily pre-treated patients. Furthermore, an ongoing trial is evaluating the all-oral combination of selinexor 40 mg, pomalidomide, and dexamethasone (SPd40) in previously treated MM patients who received prior anti-CD38 therapy. This focus on all-oral regimens simplifies patient management outside of infusion centers.

The myelofibrosis strategy also hinges on this convenience, aiming for an all-oral combination with ruxolitinib. The company expects its current liquidity, supported by XPOVIO sales and license agreements, to fund operations into the second quarter of 2026, which covers the period leading up to the SENTRY trial readout.

Patient access and affordability are managed through the KaryForward Patient Support Program. This program is critical for specialty drug access, targeting those who are uninsured or underinsured to ensure they can start and stay on therapy. Here's a quick look at what KaryForward offers:

Nurse Case Managers are available through KaryForward to help patients and caregivers. They explain prescription instructions, provide psychosocial and nonclinical education regarding XPOVIO, and help determine if additional third-party support, like transportation assistance, is available. This high-touch, non-clinical support is key to managing the patient journey.

The company's global reach also factors into customer relationships through international partners. Expanded global patient access for selinexor is translating into growth in royalty revenue, with regulatory approvals in various indications across over 50 ex-U.S. territories and countries as of mid-2025.

Karyopharm Therapeutics Inc. (KPTI) - Canvas Business Model: Channels

You're looking at how Karyopharm Therapeutics Inc. gets its product, XPOVIO, into the hands of doctors and patients, plus how they manage their pipeline awareness through clinical sites. It's a mix of direct selling for the U.S. market and relying on partners overseas.

The completion of enrollment in major trials signals a shift in focus for these sites toward data readout and potential future commercial readiness.

• Enrollment completed for the Phase 3 SENTRY trial in myelofibrosis, which evaluated selinexor in approximately 350 JAKi naïve patients.
• Enrollment of approximately 120 patients was completed in the Phase 3 XPORT-MM-031 trial in multiple myeloma in the fourth quarter of 2024.
• Top-line data from the SENTRY trial is anticipated in March 2026.

Karyopharm Therapeutics Inc. (KPTI) - Canvas Business Model: Customer Segments

Adult patients with relapsed/refractory multiple myeloma

XPOVIO (selinexor) is approved for adult patients with multiple myeloma after at least one prior therapy, in combination with VELCADE (bortezomib) and dexamethasone (XVd), or in combination with dexamethasone for heavily pre-treated multiple myeloma patients. Karyopharm Therapeutics Inc. is focused on maintaining the commercial foundation in this competitive marketplace.

The U.S. XPOVIO net product revenue guidance for the full year 2025 is in the range of $110 Million to $120 Million. For the third quarter of 2025, U.S. net product revenue was $32.0 Million, an increase of 8.5% compared to the third quarter of 2024. The first quarter of 2025 U.S. net product revenue was $21.1 Million, and the second quarter of 2025 U.S. net product revenue was $29.7 Million.

Oncologists and hematologists in community and academic settings

This segment of prescribers drives the commercial success of XPOVIO. The community setting continues to drive approximately 60% of overall net product revenue for Karyopharm Therapeutics Inc. The company's commercial focus for 2025 includes driving increased XPOVIO revenues across both the community setting and the academic setting.

Patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL)

XPOVIO holds accelerated approval in the U.S. for adult patients with diffuse large B-cell lymphoma (DLBCL), including DLBCL arising from follicular lymphoma, after at least two lines of systemic therapy. Karyopharm Therapeutics Inc. continues to expand global patient access for selinexor, which has received regulatory approvals in various indications in more than 45 countries as of early 2025.

Future: JAKi-naïve myelofibrosis patients (pending SENTRY data)

This represents a significant future customer segment, targeting JAKi-naïve myelofibrosis patients. Myelofibrosis is a rare blood cancer affecting approximately 20,000 people in the US and 17,000 people in the European Union. Karyopharm Therapeutics Inc. completed enrollment in its Phase 3 SENTRY trial for this indication with 353 patients in early September 2025. Top-line data from the SENTRY trial is on track for March 2026.

The SENTRY trial randomizes patients 2-to-1 to the selinexor arm. Historical data suggests less than half of patients achieve spleen volume response rate greater than or equal to 35% (SVR35) with approved JAK inhibitors as monotherapy. Phase 1 data for the selinexor combination showed an approximate doubling of SVR35 to nearly 80% compared to historical JAKi monotherapy data.

The commercial revenue streams are supported by the existing indications, as detailed below:

• Adult patients with relapsed/refractory multiple myeloma (after at least one prior therapy).
• Adult patients with heavily pre-treated multiple myeloma.
• Adult patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) after at least two lines of systemic therapy.

Karyopharm Therapeutics Inc. (KPTI) - Canvas Business Model: Cost Structure

You're looking at the major expenses Karyopharm Therapeutics Inc. has to cover to keep its commercial and clinical engine running. For a company like Karyopharm, the cost structure is heavily weighted toward the science and getting the drug to market.

The dominant cost is Research & Development (R&D) for clinical trials. This is where the capital goes to prove out the potential of selinexor in new indications, like the Phase 3 SENTRY trial in myelofibrosis. To be fair, even with enrollment completion in Q3 2025, there are still costs associated with trial completion and data readout, which was anticipated in the second half of 2025. Also, R&D expenses for the third quarter of 2025 were $30.5 million, which is down from $36.1 million in the third quarter of 2024, reflecting a reduced scope for one of their Phase 3 trials and cost-reduction initiatives.

Next up is Selling, General, and Administrative (SG&A) expenses for the commercial team. This covers the sales force, marketing, and general corporate overhead needed to sell XPOVIO. For the third quarter of 2025, SG&A expenses were $26.6 million, a slight decrease from $27.6 million in the third quarter of 2024.

Karyopharm Therapeutics Inc. has guided its combined operational spending for the year, lowering the range of full-year 2025 R&D and SG&A expenses to $235 million to $245 million. This signals a disciplined approach to managing the burn rate while pursuing key milestones. Honestly, keeping this combined figure in check is crucial for their cash runway, which they expect to last into the second quarter of 2026.

The third major component involves manufacturing and inventory costs for XPOVIO production, which shows up as Cost of Sales. This covers the cost of goods sold for the commercial product. For the third quarter of 2025, the Cost of Sales was $2.1 million.

Finally, you have the cost of servicing the company's debt obligations, which is the interest expense. Following refinancing transactions in the second quarter of 2024, the interest burden increased. For the third quarter of 2025, the interest expense was $11.0 million. This expense is based on the outstanding debt principal as of June 30, 2025, which included approximately $24.5 million in convertible senior notes due 2025, $116 million in 2029 Notes, and a $100 million Senior secured Term Loan.

Here's a quick look at the Q3 2025 operational costs:

You can see the combined R&D and SG&A for the quarter was $57.1 million ($30.5M + $26.6M). This quarterly run rate, if sustained, would put them near the high end of their full-year guidance range, which is why the guidance revision to $235 million to $245 million is important.

The key cost drivers Karyopharm Therapeutics Inc. manages are:

• Lowering clinical trial costs post-enrollment completion.
• Maintaining disciplined personnel and stock-based compensation expenses.
• Managing the cost of goods sold for XPOVIO.
• Servicing debt from 2024 refinancing activities.
