Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs) Primary · From start of study drug administration to 30 days after last dose of study treatment (maximum duration of 45 months)

An Adverse Event (AE) was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. TEAE was defined as an adverse event with an onset that occurs after receiving study drug. A serious adverse event (SAE) was defined as an AE that meets one or more of the mentioned criteria; is fatal, life threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, congenital anomaly/birth def

Number of Participants With Treatment-related Treatment-emergent Adverse Events Primary · From start of study drug administration to 30 days after last dose of study treatment (maximum duration of 45 months)

An AE was defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. TEAE was defined as an adverse event with an onset that occurs after receiving study drug. A treatment-related AE was any untoward medical occurrence in a clinical investigation participant administered a medicinal product; the event had a causal relationship with the treatment or usage.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. As per NCI-CTCAE version 4.03, Grade 1: asymptomatic or mild symptoms, clinical or diagnostic observations only, intervention not indicated; Grade 2: moderate, minimal, local or noninvasive intervention indicated, limiting age-appropriate instrumental activities of daily life (ADL); Grade 3: severe or medically significant but not immediately life-threatening, hospitalization or prolongation of existing hospitalization indicated, disabling, limiting self-care

Number of Participants Who Experienced Dose Limiting Toxicity (DLT) Primary · Cycle 1 only (28-day cycle)

Evaluation of DLTs was only conducted in participants who participated in the Dose-escalation Phase. A DLT was defined as any of the following, considered possibly related to drug administration, occurring in the first 28 days (or 21 days for participants on Schedule 8) at the target dose (ie, for Schedule 2 this meant the first 4 weeks after the 12 mg/m2 run-in week): Missed selinexor doses due to drug-related toxicities, discontinuation of a participant due to a toxicity that was at least possibly related to study drug before completing Cycle 1.

Recommended Phase 2 Dose (RP2D) Primary · From start of study drug administration to 30 days after last dose of study treatment (maximum duration of 45 months)

The RP2D was the maximum tolerated dose (MTD) or less. MTD was defined as the next lower dose level below the one in which \>1 of 3 participants or ≥2 of 6 participants experienced DLT, provided that dose level was ≤25 percent (%) lower than the highest (intolerable) dose tested. If the projected MTD was \>25% lower than the highest dose tested, then an additional cohort of ≥3 participants was added at a dose that was intermediate between the intolerable dose and the next lower dose.
