Brief Summary

Overview of Study Design:

This is an open phase II, single-arm, multi-center study to evaluate progression free survival in patients receiving ixazomib in combination with thalidomide and dexamethasone (ITD) followed by an ixazomib maintenance phase of a maximum period of 12 months.

The patient population will consist of adult male and female patients with multiple myeloma (MM) with relapsed and/or refractory disease after at least one prior treatment line.

In case of enrollment patients will receive ixazomib 4.0mg at days 1, 8, 15, thalidomide 100mg at days 1 to 28 (50mg in patients aged ≥75 years), and dexamethasone 40mg (20mg in patients aged ≥75 years) at days 1, 8, 15 of a 28-day treatment cycle. The proposed number of cycles is 8. Treatment will be discontinued in case of progressive disease or in case of no response after 4 cycles (≤ SD after 4 cycles). After discontinuation of therapy an end of treatment visit (EOT) will be performed within 14 days after the last dose of the last combination treatment cycle.

After 8 cycles of ITD therapy, maintenance treatment with 4.0mg ixazomib (3.0mg in patients aged ≥ 75 years at first day of maintenance phase) on days 1, 8, 15 of 28-day cycles will be administered to patients with ≥ MR for a maximum period of 12 months. Patients who completed less than 8 cycles of ITD treatment do not qualify for maintenance phase.

Follow-up visits will be performed in 3-monthly intervals until the last patient on ixazomib maintenance therapy has concluded or discontinued the maintenance phase.

A safety analysis will be conducted after enrollment of the first 6 patients and completion of at least two cycles in every patient.

Eligibility Criteria

Inclusion Criteria

1. Male or female patients 18 yrs or older.

2. Voluntary written consent

3. Patients in need of therapy with a diagnosis of relapsed or refractory multiple myeloma who had at least one prior treatment line

4. Patients must have measurable disease defined by at least 1 of the following criteria:

• Serum M-protein ≥ 10g/l
• Urine M-protein ≥ 200mg/24h
• Serum free light chain assay: involved serum light chain ≥ 10mg/dl provided that free light chain ration is abnormal

5. Life expectancy > 3 months

6. ECOG (Eastern Cooperative Oncology Group) ≤ 2

7. • ANC ≥ 1.000/mm3 and platelet count ≥ 50.000/mm3

• Total bilirubin ≤ 2 x ULN
• ALT and AST ≤ 3 x ULN
• GFR ≥ 15ml/min as calculated by cockroft-Gault equation

8. Female patients who:

• Are older than 50 years and postmenopausal for at least 1 year before the screening visit, OR
• Are surgically sterile, OR
• If they are of childbearing potential, agree to practice 2 effective methods of contraception at the same time, from 4 weeks before starting study therapy through 90 days after the last dose of study drug, OR
• Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)
• Are informed and understand the possible consequences of the teratogenic potential of thalidomide
• Male patients, even if surgically sterilized (i.e., status post-vasectomy), must agree to one of the following:
• Agree to practice effective barrier contraception during the entire study treatment period and through 90 days after the last dose of study drug, OR
• Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)
• Are informed and understand the possible consequences of the teratogenic potential of thalidomide

9. Disease free of prior malignancies for ≥ 2 years with exception of curatively treated basal cell, squamous cell carcinoma of the skin, or carcinoma "in situ" of the cervix or breast if they have undergone complete resection.

Exclusion Criteria

1. lactating females or have a positive serum pregnancy test

2. Failure to have fully recovered (i.e., ≤ Grade 1 toxicity) from the reversible effects of prior chemotherapy

3. Previous treatment with ixazomib

4. Previous treatment with bortezomib or thalidomide within the last 3 months prior to baseline visit

5. Primary refractory to, or relapsing during, or within ≤ 6 weeks after end of treatment with a proteasome inhibitor and/or thalidomide

6. Previous anti-cancer treatment within the last 21 days prior to baseline visit (cycle 1 / day 1), except corticosteroid therapy (40 - 160mg dexamethasone or corticosteroid dose equivalent per month)

7. Major surgery within 14 days before enrollment

8. Radiotherapy within 14 days before enrollment. If the involved field is small, 7 days will be considered a sufficient interval between treatment and administration of the ixazomib.

9. Central nervous system involvement

10. Infection requiring systemic antibiotic therapy or other serious infection within 14 days before study enrollment

11. Evidence of current uncontrolled cardiovascular conditions

12. Systemic treatment, within 14 days before the first dose of ixazomib, with strong inhibitors of CYP1A2 (fluvoxamine, enoxacin, ciprofloxacin), strong inhibitors of CYP3A (clarithromycin, telithromycin, itraconazole, voriconazole, ketoconazole, nefazodone, posaconazole) or strong CYP3A inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of Ginkgo biloba or St. John's wort

13. Ongoing or active systemic infection, active hepatitis B or C virus infection, or known human immunodeficiency virus (HIV) positive

14. Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of treatment according to this protocol

15. Known allergy to any of the study medications, their analogues, or excipients in the various formulations of any agent

16. Known GI disease or GI procedure that could interfere with the oral absorption or tolerance of ixazomib including difficulty swallowing

17. 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 basal cell, squamous cell carcinoma of the skin, or carcinoma "in situ" of the cervix or breast with are not excluded if they have undergone complete resection

18. Patient has ≥ Grade 3 peripheral neuropathy or Grade 2 with pain on clinical examination during the screening period
