10. Ongoing or active systemic infection, active hepatitis B or C virus infection, or known human immunodeficiency virus (HIV) positive.
11. Any serious medical or psychiatric illness that could, in the investigator’s opinion, potentially interfere with the completion of treatment according to this protocol.
12. Known allergy/intolerance to any of the study medications, their analogues, or excipients in the various formulations of any agent.
13. Known GI disease or GI procedure that could interfere with the oral absorption or tolerance of ixazomib, thalidomide and/or dexamethasone including difficulty swallowing.
14. Diagnosed or treated for another malignancy within 2 years before study enrollment or previously diagnosed with another malignancy and have any evidence of residual disease. Patients with nonmelanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection.
15. Patient has greater than or equal to Grade 2 peripheral neuropathy, or Grade 1 with pain on clinical examination during the screening period.
16. Participation in other clinical trials, including those with other investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial.
17. Patients that have previously been treated with ixazomib, or participated in a study with ixazomib whether treated with ixazomib or not.
18. Patients who are either contraindicated or unwilling to receive anticoagulation therapy.
19. Patients who are either contraindicated or unwilling to receive anti-viral prophylaxis for prevention of Varicella reactivation.
20. Patients that do not agree to be registered in, and abide by the requirements of the i-access Risk Management Program

Summary
Brief summary
The primary purpose of this trial is to evaluate the safety and efficacy of a combination of ixazomib, thalidomide and dexamethasone (ITD) for the treatment of multiple myeloma which has progressed despite one to three lines of previous therapy.
Who is it for?
You may be eligible to enroll in this trial if you are aged 18 or over, and have been diagnosed with relapsed/refractory multiple myeloma for which 1-3 prior therapies have been administered.
Study details
All participants enrolled in this trial will receive ITD therapy, which involves taking a specific regime of oral tablets across four 28-day cycles. Participants will be assessed for adverse events and progression and survival outcomes until all patients remaining on study have been followed up for at least 12 months. .
It is hoped that the findings of this study will provide information on whether the addition of ixazomib to thalidomide and dexamethason (TD) therapy is safe and effective for the treatment of relapsed/refractory multiple myeloma.
Individual patients will remain on study until disease progression, unacceptable toxicity or consent withdrawal, whichever occurs first.
