Brief summary: The purpose of this study is to compare the effectiveness of bortezomib versus thalidomide in reducing free light chains in the blood of myeloma patients. In addition participants will receive bendamustine (chemotherapy) and dexamethasone (steroids), which increase the effectiveness of both bortezomib and thalidomide. The trial will also study whether an earlier reduction of free light chains increases the chances of the kidneys recovering.

Detailed description: Renal impairment is a life threatening condition of myeloma. 20-25% of patients will present at diagnosis with renal dysfunction. Outcome is poor due to high early mortality, with 28% of newly diagnosed myeloma patients in myeloma trials with renal failure not surviving beyond 100 days, compared with 10% overall.

This study aims to establish:

1. Whether proteosomal inhibition (bortezomib) or immunomodulatory (thalidomide) based therapy achieves threshold reduction of serum free light chains (sFLCs) in a significant majority of patients.
2. Whether sFLC response to the first 2 cycles (early responder) predicts haematological and renal response to the next 2 cycles of therapy.
3. An early time point for assessment of sFLC reduction as a biomarker for response.

Participants will be stratified by age and chronic kidney disease (CKD) stage to receive either bortezomib, bendamustine and dexamethasone (BBD) or thalidomide, bendamustine and dexamethasone (BTD).

Eligibility criteria: Inclusion Criteria:

* Participant is willing and able to give informed consent for participation in the trial.
* Patients attending NHS (National Health Service) Haemato-oncology centres.
* Patients with newly diagnosed symptomatic myeloma.
* Glomerular Filtration Rate (GFR) \<30 mls/min.
* Chronic kidney disease (CKD) staging is based on estimated or measured GFR. CKD stage 4 (15-29 ml/min) and CKD stage 5 (\<15 ml/min) are eligible to enter the study. It is expected centres will consider use of fluid resuscitation and pulsed dose of steroid therapy in this group of patients to salvage renal function prior to trial screening.
* A number of patients with newly diagnosed myeloma and renal failure will have a pre-existing medical condition (hypertension, diabetes etc.) causing renal damage. Where there is a medical condition (e.g. hypertension, diabetes) which may cause renal damage, there must have been a further decline (≥15 mls/min GFR) between previous steady state and the study screening.
* Female participants of childbearing potential and male patients whose partner is a woman of childbearing potential must be prepared to use contraception in accordance with (and consent to) the Celgene-approved process for thalidomide and lenalidomide Risk Management and Pregnancy Prevention Programme.
* Women of childbearing potential must have a negative pregnancy test performed by a healthcare professional in accordance with the Celgene-approved process for thalidomide and lenalidomide Risk Management and Pregnancy Prevention.
* Free of prior malignancies for ≥ 2 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, localised prostate cancer or carcinoma "in-situ" of the cervix or breast.
* In the Investigator's opinion, is able and willing to comply with all trial requirements.
* Willing to allow his or her General Practitioner and consultant, if appropriate, to be notified of participation in the trial.

Exclusion Criteria:

* Female participant who is pregnant, lactating or planning pregnancy during the course of the trial or the female partner of a male participant planning a pregnancy during the course of the trial.
* Known allergy to investigational drugs.
* Any other significant disease or disorder which, in the opinion of the Investigator, may either put the participants at risk because of participation in the trial, or may influence the result of the trial, or the participant's ability to participate in the trial.
* Any of the following laboratory abnormalities:
* Absolute neutrophil count (ANC) \< 1.0 x10\^9/L
* Platelet count \<75 x 10\^9/L
* Serum SGOT/AST or SGPT/ALT (serum glutamic oxaloacetic transaminase/aspartate aminotransferase or serum glutamic pyruvic transaminase/alanine aminotransferase) \>3 x upper limit of normal.
* Use of any standard/experimental anti-myeloma drug therapy excluding dexamethasone 14 days prior to trial entry.
* CKD stages \< 4.
* Intention to use a physical method of serum free light chain removal such as plasma exchange or high cut off dialysis.
* Grade 2 neuropathy or more (National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v 4.0) will preclude use of thalidomide and bortezomib.
* Participants who have participated in another research trial involving an investigational product in the past 12 weeks.
* Contraindicated to receive either one of the study drugs, thalidomide, bortezomib, bendamustine based on the respective summary of product characteristics.
