Group Intervention Description IXAZOMIB IXAZOMIB Part A: Participants will receive a single dose of 4.1-milligram (mg) \[14C\]-IXAZOMIB oral solution containing approximately 500-nCurie (nCi) of total radioactivity on Day 1 and remain at the clinic for 8 days. On Days 14 and 21, participants may be administered a single 4.0-mg capsule of IXAZOMIB. Participants will return to the clinic in the evening before Days 14, 21, 28, and 35 for a 24-hour overnight clinic visit. Part B: Eligible participants from Part A may continue into Part B once they have completed their Day 35 assessments in Part A. Participants may receive IXAZOMIB capsules administered orally at a dose of 4.0-mg once weekly on Days 1, 8, and 15 of 28-day cycles. Participants will continue in this study until disease progression or unacceptable toxicity.
- Primary Outcome Measures
Name Time Method Part A: Cmax: Maximum Observed Plasma Concentration for Ixazomib Day 1 of Part A pre-dose and at multiple timepoints (up to Day 14) post-dose Maximum observed plasma concentration (Cmax) is the peak plasma concentration of ixazomib, obtained directly from the plasma concentration-time curve.
Part A: Tmax: Time to Reach the Cmax for TRA Day 1 of Part A pre-dose and at multiple timepoints (up to Day 35) post-dose Time to reach the maximum observed plasma concentration (Cmax) for TRA, equal to time (hours) to Cmax for TRA after administration, obtained directly from the plasma TRA concentration-time curve.
Part A: Cumulative Percentage of the Total Radioactivity Dose Excreted in Feces Day 1 of Part A pre-dose and at multiple timepoints (up to Day 35) post-dose Percentage of the TRA dose excreted in feces from Day 1 to Day 35 of Part A
Part A: Tmax: Time to Reach the Maximum Observed Plasma Concentration (Cmax) for Ixazomib Day 1 of Part A pre-dose and at multiple timepoints (up to Day 14) post-dose Time to reach the maximum observed plasma concentration (Cmax), equal to time (hours) to Cmax of ixazomib after administration, obtained directly from the plasma concentration-time curve.
Part A: Renal Clearance of Ixazomib Day 1 pre-dose and at multiple timepoints (up to Day 14) post-dose Renal clearance is the volume of plasma from which ixazomib is completely removed by the kidney in a given amount of time, calculated as the amount of ixazomib excreted in the urine divided by the area under the plasma ixazomib concentration-time curve.
Part A: AUC(0-312): Area Under the Plasma Concentration-time Curve From Time 0 to 312 Hrs Post-dose for Ixazomib Day 1 of Part A pre-dose and at multiple timepoints (up to 312 hrs) post-dose AUC(0-312) is a measure of the area under the plasma concentration time-curve from time zero to 312 hrs post-dose for ixazomib.
Part A: AUC(0-816): Area Under the Plasma Concentration-time Curve From Time 0 to 816 Hrs Post-dose for TRA Day 1 of Part A pre-dose and at multiple timepoints (up to 816 hrs) post-dose AUC(0-816) is a measure of the area under the plasma concentration time-curve from time zero to 816 hrs post-dose for TRA.
Part A: Cmax: Maximum Observed Whole Blood Concentration of TRA Day 1 of Part A pre-dose and at multiple timepoints (up to Day 35) post-dose Maximum observed whole blood concentration (Cmax) of a TRA is the peak whole blood concentration of TRA, obtained directly from the whole blood TRA concentration-time curve.

- Secondary Outcome Measures
Name Time Method Number of Participants With TEAEs Related to Investigations System Organ Class for Laboratory Values Baseline up to Cycle 5 Day 45 Number of Participants With TEAEs Related to Vital Signs Baseline up to Cycle 5 Day 25 Vital signs included oral body temperature, heart rate, and blood pressure.
Ixazomib and Metabolites as Percent of Total Radioactivity in Plasma Day 1 pre-dose and at multiple time points (up to 816 hrs) post-dose The plasma samples were pooled for participants over 816 hrs post-dose, and data was analysed using the Hamilton method time-proportional pooling, and therefore the data is reported as "percent of total radioactivity in plasma" with measure type as "number" and measure dispersion as "Not applicable, NA".
Ixazomib and Metabolites as Percent of Total Dose Administered in Urine Day 1 pre-dose and at multiple time points (up to Day 35) post-dose The 35-day post-dose data is extrapolated from the average of four participant data from 0-168-hr pooled urine. The data is therefore reported as "percentage of dose" with measure type as "number" and measure dispersion as "NA".
Ixazomib and Metabolites as Percent of Total Dose Administered in Feces Day 1 pre-dose and at multiple time points (up to Day 35) post-dose The 35-day post-dose data is extrapolated from the average of four participant data from 0-168-hr pooled feces. The data is therefore reported as "percentage of dose" with measure type as "number" and measure dispersion as "NA".
Number of Participants Reporting One or More Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) Baseline up to Cycle 5 Day 45
