An Intensive Program With Quadruplet Induction and Consolidation Plus Tandem Autologous Stem Cell Transplantation in Newly Diagnosed High Risk Multiple Myeloma Patients

Prior treatment

• Subjects must not have been treated previously with any systemic therapy for multiple myeloma. Prior treatment with corticosteroids or radiation therapy does not disqualify the subject (the maximum dose of corticosteroids should not exceed the equivalent of 160 mg of dexamethasone in a 2-week period). Two weeks must have elapsed since the date of the last radiotherapy treatment. Enrolment of subjects who require concurrent radiotherapy (which must be localized in its field size) should be deferred until the radiotherapy is completed and 2 weeks have elapsed since the last date of therapy
• Subject has received daratumumab or other anti-CD38 therapies previously
• Myocardial infarction within 6 months prior to enrolment according to NYHA Class III or IV heart failure, uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities
• Systemic treatment with strong inhibitors of CYP1A2 (fluvoxamine, enoxacin), strong inhibitors of CYP3A (as clarithromycin, telithromycin, itraconazole, voriconazole, ketoconazole, nefazodone, posaconazole) or strong CYP3A inducers (as rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, fosphenytoin phenobarbital), or use of Ginkgo biloba or St. John's wort within 14 days before the first dose of study treatment.
• Known intolerance to steroid therapy
• Subject has had major surgery within 2 weeks before the first dose of study treatment or will not have fully recovered from surgery, or has surgery planned during the time the subject is expected to participate in the study. Kyphoplasty or Vertebroplasty are not considered major surgery.

Other illness

• Subject has a diagnosis of Waldenström's macroglobulinemia, or other conditions in which IgM M-protein is present in the absence of a clonal plasma cell infiltration with lytic bone lesions.
• Uncontrolled hypertension
• Subjects with known chronic obstructive pulmonary disease (COPD) with a Forced Expiratory Volume (FEV1) in 1 second \< 50% of predicted normal. Note that FEV1 testing is required for patients suspected of having COPD and subjects must be excluded if FEV1 \< 50% of predicted normal.
• Subjects with a history of moderate or severe persistent asthma within the past 2 years, or with uncontrolled asthma of any classification at the time of screening (Note that subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed in the study).
• History of hypersensitivity to any of the study medications, their analogues, or excipients in the various formulations, or to study-required co medication
• Clinically relevant active infection or serious co-morbid medical conditions
• Prior malignancy except adequately treated basal cell or squamous cell skin cancer, in situ cervical, breast or prostate cancer free of disease since 5 years.
• Female subject who is pregnant or breast-feeding + male and female refusing birth control conditions
• Serious medical or psychiatric illness likely to interfere with participation in study
• Uncontrolled diabetes mellitus
• Known HIV infection; Known active hepatitis B or C viral infection; or other ongoing uncontrolled infection
• Incidence of gastrointestinal disease that may significantly after the absorption of oral drugs

Lab values

• Subject has plasma cell leukemia (according to WHO criterion: ≥ 20% of cells in the peripheral blood with an absolute plasma cell count of more than 2 × 10\^9/L) or polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes syndrome.

Other

• Subject has a diagnosis of primary amyloidosis, monoclonal gammopathy of undetermined significance, smoldering multiple myeloma, or solitary plasmacytoma.
• Subject has had plasmapheresis within 28 days of C1D1.
• Subject is exhibiting clinical signs of meningeal involvement of multiple myeloma.
• Subjects unable or unwilling to undergo antithrombotic prophylactic treatment
• Person under guardianship, trusteeship or deprived of freedom by a judicial or administrative decision

• Male or female subjects, 18 years of age or older, younger than 66 years (\< 66 years)
• Voluntary written informed consent must be given before performance of any study-related procedure not part of normal medical care, with the understanding that the subject may withdraw consent at any time without prejudice to future medical care.
• Subject must have documented multiple myeloma satisfying the Diagnostic criteria for symptomatic Myelome Multiple and measurable disease as defined by:
  • Monoclonal plasma cells in the bone marrow ≥ 10% or presence of a biopsy proven plasmacytoma AND any one or more of the following myeloma defining events:
  • Hypercalcemia: serum calcium \> 0.25 mmol/L higher than ULN or \> 2.75 mmol/L
  • Renal insufficiency: creatinine clearance \< 40mL/min or serum creatinine \> 177 μmol/L
  • Anemia: hemoglobin \> 2 g/dL below the lower limit of normal or hemoglobin \< 10 g/dL
  • Bone lesions: one or more osteolytic lesions on skeletal radiography, CT or PET-CT Or in a patient with indolent myeloma
  • Clonal bone marrow plasma cell percentage ≥ 60%
  • Involved: uninvolved serum free light chain ratio ≥ 100
  • Superior 1 focal lesion on MRI studies
  • Measurable disease as defined by the following:
  • M-component ≥ 5g/l, and/or urine M-component ≥ 200 mg/24h and/or serum Free Light Chain ≥ 100 mg/l.
• Newly diagnosed subjects eligible for high dose therapy and autologous stem cell transplantation
• Subject must have high risk disease according to FISH analysis: del(17p), or t(14;16) or t(4;14). The FISH-positivity cut-off value for defining the presence of del(17p) in this study is 50%
• Karnofsky performance status score ≥ 50%
• Women of childbearing potential must have a negative serum or urine pregnancy test within 10 to 14 days prior to therapy and repeated within 24 hours before starting study drug. They must commit to continued abstinence from heterosexual intercourse or begin 2 acceptable methods of birth control used at the same time, beginning at least 4 weeks before initiation of lenalidomide treatment and continuing for at least 30 days after the last dose of Lenalidomide. Women must also agree to notify pregnancy or doubt upon pregnancy during the study.
• Men must agree to not father a child and agree to use a latex condom during therapy and for 4 weeks after the last dose of study drug, even if they have had a successful vasectomy, if their partner is of childbearing potential.
• Subject must have pretreatment clinical laboratory values meeting the following criteria during the Screening Phase (Lab tests should be repeated if done more than 15 days before C1D1):
