NEWTON, Mass. November 4, 2019 Karyopharm Therapeutics Inc. (Nasdaq:KPTI), an oncology-focused pharmaceutical company, today
reported financial results for the third quarter 2019. In addition, Karyopharm highlighted select corporate milestones, including an update regarding the initial U.S. commercial launch of
XPOVIO (selinexor), and provided an overview of its key clinical development programs.
This has been a landmark quarter for Karyopharm as we saw the accelerated approval and commercial launch of XPOVIO, the first and only oral nuclear
export inhibitor approved in the U.S., indicated for patients with heavily pretreated multiple myeloma, said Michael G. Kauffman, MD, PhD, Chief Executive Officer of Karyopharm. The XPOVIO launch is off to a very strong start and we are
extremely pleased with the early commercial uptake and feedback from prescribing physicians. As we look ahead to the next few months, we eagerly await the top-line results from the ongoing Phase 3 BOSTON
study, which, if positive, would represent another significant advancement in the treatment of patients with relapsed or refractory multiple myeloma. Finally, we remain on track to file, by the end of 2019, a New Drug Application in the U.S. for
selinexor requesting accelerated approval for patients with relapsed or refractory diffuse large B-cell lymphoma.
Third Quarter 2019 Highlights and Recent Progress
XPOVIO (selinexor) in Multiple Myeloma
Third quarter sales were driven by a combination of new patient
starts, prescription refills, and initial channel inventory to Karyopharm s distribution partners. Patient demand for XPOVIO continued to increase in each subsequent month of the quarter following its accelerated approval by the U.S. Food and
Drug Administration (FDA) in July. Rapid insurance coverage for XPOVIO has been a key contributor to its early commercial success with XPOVIO already being added to numerous national commercial and Medicare formularies and coverage
policies. Based on prescription fulfillment data through the specialty pharmacy channel, Karyopharm estimates that approximately 60% of XPOVIO prescriptions have been dispensed to patients with
Medicare coverage and 35% to patients with commercial insurance, with the remaining 5% of patients having either Medicaid or another form of prescription coverage.

Corporate and Financial Updates
Third Quarter 2019 Financial Results
Net product revenue for the quarter ended September 30, 2019 was $12.8 million, which reflects the first quarter of recorded sales for XPOVIO.
Karyopharm did not have any product revenue for the quarter ended September 30, 2018.
License and other revenue for the third quarter 2019 was
$0.3 million, compared to $0.2 million for the third quarter of 2018.
Cost of sales for the third quarter 2019, was $1.0 million, which
reflects the costs of XPOVIO units sold and third-party royalties on our net product revenue. Karyopharm did not have any cost of sales for the third quarter 2018.
Research and development expense for the third quarter 2019 was $26.3 million, compared to $36.4 million for the third quarter of 2018. Karyopharm
expects research and development expense to be relatively consistent for the final quarter of 2019 compared to the third quarter of 2019. For the third quarter 2019, selling, general and administrative expense was $25.3 million, compared to
$13.0 million for the third quarter 2018. The increase in selling, general and administrative expenses compared to the prior year period was due primarily to the hiring of the Karyopharm commercial team and related activities to support the
U.S. commercial launch of XPOVIO.
Karyopharm reported a net loss of $41.4 million, or $0.67 per share, for the third quarter 2019, compared to a net
loss of $48.1 million, or $0.79 per share, for the third quarter 2018. Net loss includes non-cash stock-based compensation expense of $3.7 million and $4.8 million for the 2019 and 2018
quarters, respectively.
Cash, cash equivalents, restricted cash and investments as of September 30, 2019 totaled $270.3 million, compared to
$330.9 million as of December 31, 2018.
2019 Financial Outlook
Based on its current operating plans, Karyopharm expects its non-GAAP operating expenses, which excludes stock-based
compensation expense, for the full year 2019 to be in the range of $200 million to $210 million. Karyopharm has not reconciled the full year 2019 outlook for non-GAAP operating expenses to full year
2019 outlook for GAAP operating 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 2019 outlook for non-GAAP operating expenses.
The Company expects that its existing cash, cash
equivalents and investments, and the revenue it expects to generate from XPOVIO product sales, will be sufficient to fund its planned operations into the middle of 2021.
Additional key activities expected in the remainder of 2019 include supporting the ongoing multiple myeloma regulatory filing for selinexor in Europe,
progressing the pivotal Phase 3 BOSTON study in multiple myeloma and submitting an NDA in the U.S. in DLBCL.
Non-GAAP Financial Information
Karyopharm uses a non-GAAP financial measure, non-GAAP operating expense, to
provide operating expense guidance. Karyopharm believes this non-GAAP financial measure is useful to investors because it provides greater transparency regarding Karyopharm s operating performance as it
excludes non-cash stock compensation expense. This non-GAAP financial measure should not be considered a substitute or an alternative to GAAP total
operating expense and should not be considered a measure of Karyopharm s liquidity. Instead, non-GAAP operating expense should only be used to
supplement an understanding of Karyopharm s operating results as reported under GAAP.

candidates that receive regulatory approval; 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 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 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; Karyopharm s
ability to obtain and maintain requisite regulatory approvals and to enroll patients in its clinical trials; unplanned cash requirements and expenditures; development of drug candidates by Karyopharm s competitors for diseases in which
