Multiple Myeloma
Conditions
Brief summary
This study will evaluate the efficacy and safety of 3-drug all-oral combination, ixazomib plus lenalidomide plus dexamethasone (IRd) as induction treatment for autologous stem cell transplantation eligible patients followed by IRd consolidation and risk based maintenance treatment with IR or R alone.
Detailed description
This Nordic Myeloma Study Group study is phase 2 study for newly diagnosed transplant eligible myeloma patients between 18 - 70 years of age. Patients will have four IRd cycles of 28 day each as induction consisting of ixazomib 4 mg on days 1, 8 and 15 and lenalidomide 25 mg on days 1-21 and dexamethasone 40 mg on days 1, 8, 15 and 22. After autologous stem cell mobilisation and transplantation patients will receive 2 consolidation cycles with the same combination as during induction. This is followed by risk based maintenance so that high-risk patients will have ixazomib plus lenalidomide maintenance and standard-low risk patients lenalidomide alone. The treatment will continue until progression or excess toxicity. The primary endpoint is minimal residual disease \< 0.01% assessed by 8-color flow cytometry (EuroFlow) and secondary endpoint is achievement of minimal residual negativity status assessed by 8-color flow cytometry. Other secondary endpoints are safety, improvement of response during maintenance treatment, progression free survival, time to next treatment, quality of life and overall survival.

Inclusion criteria
1. Newly diagnosed transplant eligible male or female multiple myeloma patients, 18-70 years of age, who have not received prior treatment for multiple myeloma 2. Symptomatic and measurable disease diagnosed by standard criteria (International Myeloma Working Group, CRAB criteria) 3. Voluntary written informed consent must be given before performance of any study related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care. 4. Female patients who: * Are postmenopausal for at least 1 year before the screening visit, OR * Are surgically sterile, OR * If they are of childbearing potential, fertile, agree to practice 2 effective methods of contraception, at the same time, and agree to ongoing pregnancy testing and adhere to the guidelines of the lenalidomide pregnancy prevention program from the time of signing the informed consent form 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 \[eg, calendar, ovulation, symptothermal, post-ovulation methods\] and withdrawal are not acceptable methods of contraception.) Male patients, even if surgically sterilized (ie, status post-vasectomy), must agree to one of the following: • Agree to practice effective barrier contraception and adhere to the guidelines of the lenalidomide pregnancy prevention program 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 (eg, calendar, ovulation, symptothermal, post-ovulation methods\] and withdrawal are not acceptable methods of contraception. 4\. Patients must have a diagnosis of a symptomatic multiple myeloma without any previous therapies except dexamethasone 160 mg dose, or comparable dose of other steroids, and local radiotherapy for symptom control 5. Eastern Cooperative Oncology Group (ECOG) performance status and/or other performance status 0, 1, or 2. 6\. Patients must meet the following clinical laboratory criteria: * Absolute neutrophil count (ANC) ≥ 1,000/mm3 (≥ 1.0 x 109/L) and platelet count ≥ 75,000/mm3 (75 x 109/L). Platelet transfusions to help patients meet eligibility criteria are not allowed within 3 days before study enrollment. * Total bilirubin ≤ 1.5 × the upper limit of the normal range (ULN). * Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 × ULN. * Calculated creatinine clearance ≥ 30 mL/min (Cockcroft-Gault estimation of creatinine clearance (CRcl): CRcl (mL/min) = (140 - age) (weight \[kg\]) / 72 (serum creatinine \[mg/dL\]); for females, multiply by 0.85 (Cockcroft DW. 1976, Luke DR. 1990). 7\. Patient must be willing and able to adhere to the study protocol visit schedule and other protocol requirements. 8\. Negative pregnancy test at inclusion if applicable
Exclusion criteria
* 1\. Female patients who are lactating or have a positive serum pregnancy test during the screening period. 2\. Major surgery within 14 days before enrollment. 3. Radiotherapy within 14 days before enrollment 4. Central nervous system involvement with multiple myeloma. 5. Infection requiring systemic antibiotic therapy or other serious infection within 14 days before study enrollment. 6\. Inability, unwillingness or contraindication to use thrombosis prophylaxis or antithrombotic therapy or herpes zoster prophylaxis 7. Evidence of current uncontrolled cardiovascular conditions, including uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, or myocardial infarction within the past 6 months. 8\. Systemic treatment, within 14 days before the first dose of ixazomib, strong CYP3A inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of Ginkgo biloba or St. John's wort. 9\.
