Corporate Presentation June 2018 Targeting Disease at the Nuclear Pore Exhibit 99.1
Forward-looking Statements This presentation contains forward-looking statements within the meaning of the “safe harbor” provisions of The Private Securities Litigation Reform Act of 1995. Such forward-looking statements include those regarding the therapeutic potential of and potential clinical development plans and commercialization for Karyopharm’s drug candidates, including the timing of initiation of certain trials, of the reporting of data from such trials, of the submissions to regulatory authorities and of potential commercial launches, the potential availability of accelerated approval pathways, the potential size of the markets for multiple myeloma drugs and multiple myeloma drugs for treatment of patients with relapsed multiple myeloma and Karyopharm’s strategic and financial plans and expectations as well as financial projections for Karyopharm. Such statements are subject to numerous important factors, risks and uncertainties that may cause actual events or results to differ materially from Karyopharm’s current expectations. For example, there can be no guarantee that regulators will agree that selinexor qualifies for accelerated approval in the U.S. or conditional approval in the E.U. as a result of the data from the STORM study in patients with penta-refractory myeloma or SADAL study in patients with relapsed/refractory DLBCL or that any of Karyopharm’s drug candidates, including selinexor (KPT-330) and eltanexor (KPT-8602), Karyopharm’s second generation SINE compound, or KPT-9274, Karyopharm’s first-in-class oral dual inhibitor of PAK4 and NAMPT, or any other drug candidate Karyopharm is developing, will successfully complete necessary preclinical and 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 Karyopharm’s drug candidate portfolio will result in stock price appreciation. In addition, even if Karyopharm receives marketing approval for selinexor or another drug candidate, there can be no assurance that Karyopharm will be able to successfully commercialize that drug candidate. Management’s expectations and, therefore, any forward-looking statements in this presentation could also be affected by risks and uncertainties relating to a number of other factors, many of which are beyond Karyopharm’s control, including the following: Karyopharm’s results of clinical trials and preclinical studies, including subsequent analysis of existing data and new data received from ongoing and future studies; the content and timing of decisions made by the FDA and other regulatory authorities, investigational review boards at clinical trial sites and publication review bodies, including with respect to the need for additional clinical studies; 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; unplanned cash requirements and expenditures; development of drug candidates by Karyopharm’s competitors for diseases for which Karyopharm is currently developing its drug candidates; that the markets for multiple myeloma drugs will grow as predicted; and Karyopharm’s ability to obtain, maintain and enforce patent and other intellectual property protection for any drug candidates it is developing. These and other risks, including those which may impact management’s expectations, are described in greater detail under the heading "Risk Factors" in Karyopharm’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2018, which is on file with the SEC, and in subsequent filings filed by Karyopharm with the SEC. Any forward-looking statements contained in this presentation are for informational purposes only and speak only as of the date hereof. Other than as is 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.

Selinexor: A Growing Body of Safety Data 2,400 Total patients treated to date Favorable emerging tolerability profile; multiple ongoing Phase 3 studies Dosing regimens utilized in key Phase 2 and 3 trials (e.g., BOSTON, STORM, STOMP, SADAL and SEAL) have shown generally predictable and manageable tolerability, particularly when used once weekly in combination regimens Common side effects are generally predictable across multiple tumor types and generally reversible and/or manageable with standard supportive care Combination regimens have demonstrated a predictable and manageable tolerability profile, with observed additive or synergistic activity and potential to re-sensitize to prior therapies Phase 3 BOSTON selinexor regimen allows for use of 40% less Velcade® and 25% less dexamethasone than standard Velcade® and dexamethasone dosing In certain trials, side effects reported from treatment arms evaluating selinexor and dexamethasone in combination with other anti-myeloma agents are similar to, or reduced, compared to selinexor and dexamethasone alone ~48 Number of clinical trials ongoing and/or completed ©2018 Karyopharm Therapeutics Inc. 1 Per ClinicalTrials.gov (as of Apr 26, 2018); 5 of 46 are company-sponsored and currently enrolling >10 Number of cancers explored 1

STORM: A Phase 2b Study In Myeloma Safety: Predictable and manageable tolerability profile; results consistent with those reported previously from Part 1 of STORM and from other selinexor studies. As anticipated, the most common non-hematologic AEs were nausea, vomiting, fatigue and reduced appetite; primarily low grade and manageable with standard supportive care and/or dose modification. The most common hematologic AEs were Grade ≥3 cytopenias and were generally not associated with clinical sequelae. No new safety signals.
