Participants are not considered to have a currently active malignancy, if they have completed therapy and are considered by their physician to be at least less than 30% risk of relapse over next 3 months.~* Active psychiatric illnesses/social situations that would limit compliance with protocol requirements.~* Active or uncontrolled autoimmune disease that may require corticosteroid therapy during study.~* Severely compromised immunological state, including known human immunodeficiency virus (HIV).~* Known acute or chronic hepatitis B or C.~* Chemotherapy and other investigational therapies (targeted or immunotherapy) will require a 3-week washout period before treatment initiation.~* Initiation of bisphosphonate therapy within 4 weeks prior to first dose of study treatment. Participants receiving ongoing bisphosphonate or denosumab therapy must have been on stable doses for at least 4 weeks prior to receiving first dose of study treatment. Participants on stable doses of bisphosphonates who show subsequent tumor progression may continue on this medication.~* Impaired cardiac function or clinically significant cardiac diseases, including any of the following:~  1. History or presence of serious uncontrolled ventricular arrhythmias or presence of uncontrolled atrial fibrillation.~ 2. Clinically significant resting bradycardia (\< 50 beats per minute).~ 3. Any of the following within 3 months prior to study entry: myocardial infarction severe/unstable angina, Coronary Artery Bypass Graft, Grade 3 or 4 Congestive Heart Failure, Cerebrovascular Accident, Transient Ischemic Attack, or Pulmonary Embolism.~ 4. Uncontrolled hypertension, as defined by a systolic blood pressure \> 160 mm Hg and/or a diastolic blood pressure \> 90 mm Hg with or without anti-hypertensive medication.~ 5. Previous pericarditis; clinically significant pleural effusion in the previous 12 months or current ascites requiring 2 or more interventions per month.~ 6. Angina at rest.~* Any acute toxicities due to prior chemotherapy and/or radiotherapy that have not resolved to a National Cancer Institute (NCI) common terminology criteria for adverse events (CTCAE), version 4.03 Grade of ≤ 1.

Two methods of contraception must be used by participants and their partners through the study and for 3 months after the end of study treatment.~* Body mass index (BMI) \< 1.2 m\^2, in order to prevent a participant from receiving a dose of selinexor \> 70 mg/m\^2.
