Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 10
Healthy volunteers: no

Brief summary:
The purpose of this study is to evaluate the effectiveness and safety of bortezomib in participants previously treated for multiple myeloma (cancer of plasma cells in bone marrow causing numerous tumors and characterized by the presence of abnormal proteins in the blood) with limited kidney function.

Detailed description:
This is an open label (all people know the identity of the intervention), multi-center (study conducted at multiple sites), non-comparative, single arm study of bortezomib. The study consists of 3 phases: Screening phase (21 days before Day 1 of cycle 1); Treatment phase (consist of 8 cycles each cycle of 21 days or until disease progression or unacceptable toxicity); and a Follow-up phase (for participants with positive treatment response or stable disease at the final visit). Follow-up for disease progression will be done in every 3 months up to 2 years. Participants who will experience disease progression after completing at least 2 cycles of bortezomib treatment or have no change from baseline in stable disease after completing at least 4 cycles or as per Investigator's discretion will receive dexamethasone. Efficacy will be primarily evaluated by percentage of participants with renal compromised Multiple Myeloma by International Myeloma Working Group (IMWG) uniform response criteria. Participants' safety will be monitored throughout the study.

Arms:
arm 1: Bortezomib 1.3 milligram (mg) per meter\^2 (m\^2) bolus (a large amount) intravenous (into the vein) injection will be administered once daily on Days 1, 4, 8 and 11 of each 21-day cycle with addition of Dexamethasone 20 mg per day administered orally, once daily on Days 1 and 2, Days 4 and 5, Days 8 and 9 and Days 11 and 12 of each 21-day cycle as per Investigator's discretion for those participants who experience disease progression after treatment completion up to Cycle 2 or have no change from Baseline after completion of at least 4 cycles. The treatment will be given up to 8 cycles (24 weeks).

Interventions: intervention 1: Dexamethasone intervention 2: Bortezomib
Intervention descriptions: intervention 1: Dexamethasone 20 mg per day will be administered orally on Days 1 and 2, Days 4 and 5, Days 8 and 9 and Days 11 and 12 of each 21-days cycle as per Investigator's discretion for those participants who experience disease progression after treatment completion up to Cycle 2 or have no change from Baseline after completion of at least 4 cycles. The treatment will be given up to 8 cycles (24 weeks). intervention 2: Bortezomib 1.3 milligram per meter\^2 (mg/m\^2), bolus intravenous injection will be administered on Days 1, 4, 8 and 11 of each 21-day cycle and up to 8 cycles.
