Maximum Tolerated Dose (MTD) for KPT-9274Primary· From start of study drug administration up to 44 weeks
The MTD was defined as the highest dose at which less than or equal to (\<=) 1 participant experienced a dose limiting toxicity (DLT) in Cycle 1. A DLT was defined as an adverse event (AE) or abnormal laboratory value occurring within the first 28 days of treatment of KPT-9274, excluding those clearly caused by underlying disease, disease progression, or external factors.

Number of Participants With Adverse Event (AE) of Severity Grade >= 3 or 4, Serious AEs, and AEs Leading to Treatment DiscontinuationPrimary· From start of study drug administration up to 49 weeks
The AE severity was graded on a scale from 1 to 4 using the National Cancer Institute Common Terminology Criteria for Adverse Events, Version 4.03; any events not specifically listed in the scale were defined as: Grade 1 is mild; Grade 2 is moderate; Grade 3 is severe or medically significant; Grade 4 is life-threatening. An SAE was any untoward medical occurrence that at any dose met one, more of the following criteria: results in death, life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent, significant disability/incapacity, a
