phase 2 study with minimal residual disease (mrd) driven adaptive strategy in treatment for newly diagnosed multiple myeloma (mm) with upfront daratumumab-based therapy

Conditions: Multiple Myeloma

Summary: this phase 2 trial will test whether the combination of darard (daratumumab + lenalidomide + dexamethasone) as induction therapy, followed by drvd (daratumumab + lenalidomide + bortezomib + dexamethasone) consolidation therapy, if needed, will result in more patients achieving minimal residual disease (mrd)-negative status, relative to the standard of care. consolidation therapy will be administered only to those patients with mrd-positive status after induction therapy. this is a study based on adaptive design for decision making of treatment options. duration of therapy (daratumumab cycles) will depend on individual approach, response, evidence of disease progression and tolerance.

that in the opinion of the investigator places the subject at unacceptable risk if subject were to participate in the study. 11. major surgery ≤ 2 weeks prior to starting study drug or who have not recovered from complications of the surgery. 12. clinically significant peripheral neuropathy not well controlled with treatment, defined as symptoms limiting activities of daily living (basic adls).

predicted normal. 15. clinically uncontrolled asthma of any classification or known moderate or severe persistent asthma within the past two years (see asthma guidelines. https://www.nhlbi.nih.gov/files/docs/guidelines/asthma_qrg.pdf). 16. serious intercurrent illness including but not limited to clinically relevant cerebrovascular disease, uncontrolled diabetes mellitus, cirrhosis, pulmonary disease. 17. active autoimmune process or other disease requiring systemic immunosuppressive, monoclonal antibody, small molecule, or radiation therapy. however local radiation for myeloma related symptomatic treatment is allowed 18. participant is: * seropositive for hiv * seropositive for hepatitis b (defined by a positive test for hepatitis b surface antigen \[hbsag\] * subjects with resolved infection (i.e., subjects who are hbsag negative but positive for antibodies to hepatitis b core antigen \[anti-hbc\] and/or antibodies to hepatitis b surface antigen \[anti-hbs\]) must be screened using real-time polymerase chain reaction (pcr) measurement of hepatitis b virus (hbv) dna levels. those who are pcr positive will be excluded. * participants with serologic findings suggestive of hbv vaccination (anti-hbs positivity as the only serologic marker) and a known history of prior hbv vaccination, do not need to be tested for hbv dna by pcr. *
