Selinexor will be given orally at a dose of 60mg once weekly on the first day of the week (day 1, 8, 15, and 22) for Cycle 1 and up to Cycle 12.
Dexamethasone will be given orally at a dose of 20mg, if tolerated, or at a reduced dose if required, 30 to 60 minutes prior to selinexor for first 2 days of each week only (days 1, 2, 8, 9, 15, 16, 22, and 23 of each cycle).

Compare number of dose limiting toxicity (DLT) occurence to measure safety and toxicity
Safety and toxicity will be determined by how many occurrence of dose limiting toxicity (DLT) occured during 12 months of treatment for each subject
Time frame: approximately 12 months
Compare Hematologic Overall Response Rate (ORR)
Comparing proportion of subjects with Complete Response (CR), Very Good Partial Response (VGPR), Partial Response (PR), No Response (NR) and Progressive Disease (PD)
Time frame: approximately 12 months
Hematologic Very Good Partial Response (VGPR) or better rate
Percentage of subjects that achieved Very Good Partial Response (VGPR) or better response
Time frame: approximately 12 months
Hematologic Complete Response (CR) rate
Percentage of subjects that achieved Complete Response (CR)
Time frame: approximately 12 months
Stringent dFLC response rate
Percentage of subjects that has stringent dFLC (dFLC is defined as the difference in involved amyloidogenic and uninvolved serum-free light chains).
Time frame: approximately 12 months
Number of patients with peripheral blood mass spectrometry for monoclonal protein detection (MALDI-TOF)
For each subject, detection of monoclonal protein will be analyzed at screening, day 1 of each cycle (only when in ≥VGPR), at each end of treatment (EOT) visits, and day 1 of each post-treatment follow, up until PD or 24 months, whichever occurs first.

minimal residual disease (MRD) negative CR/VGPR rate
Percentage of subjects that is MRD negative when in complete response (CR) and Very Good Partial Response (VGPR)
Time frame: approximately 12 months
Percentage of participants with organ response
Organ response for kidney and cardiac is defined as the proportion of baseline organ involved participants who achieve organ response in each corresponding organ. Organ response defined for cardiac: N-terminal brain pronatriuretic peptide (NT-proBNP) response (\> 30% and \> 300 nanogram per liter \[ng/L\] decrease in participants with baseline NT-proBNP \>= 650 ng/L) or New York Heart Association (NYHA) class response (\>= 2 class decrease in participants with baseline NYHA class 3 or 4); for kidney: decrease in proteinuria by \>=30% or below 0.5 grams /24 hours without renal progression.
Time frame: End of Study (approximately 3 years)
Median hematologic Progression Free Survival (PFS)
Median estimate of months that participants have progression free survival and median estimate is calculated using the Kaplan-Meier methodology
Time frame: End of Study (approximately 3 years)
Time to first hematologic response
Measured in months between the date of enrollment and the first efficacy evaluation at which the participant has met the criteria for hematologic complete response.
Time frame: approximately 12 months
Time to best hematologic response
Measured in months between the date of enrollment and the best hematologic response the subject achieved while on treatment
Time frame: approximately 12 months
Time to hematologic progression
Measured in months between the date of enrollment and the first efficacy evaluation at which the participant has met the criteria for hematologic progression
Time frame: End of Study (approximately 3 years)
Duration of hematologic response
Duration of hematologic response is defined as the time between the date of initial documentation of hematologic response (i.e. Complete Response, Very Good Partial Response, Partial Response, No Response and Progressive Disease) to the date of the next hematologic response
Time frame: End of Study (approximately 3 years)
Time to next therapy
Measured in months from the date of enrollment to the start date of subsequent treatment for AL amyloidosis
Time frame: End of Study (approximately 3 years)
Median organ Progression Free Survival (PFS)
Measured in months between the date of enrollment and the first efficacy evaluation at which the participant has met the criteria for hematologic complete response.
Time frame: End of Study (approximately 3 years)
Time to organ response
Measured in months between the date of enrollment and the organ response
Time frame: approximately 12 months
Time to organ progression
Measured in months between the date of organ response to organ progression
Time frame: End of Study (approximately 3 years)
Duration of organ response
Measured in months between the date of initial documentation of organ response to organ progression
Time frame: End of Study (approximately 3 years)
