In plain words

This report gives the results of more than five years of follow-up of the MAIA study, in which people with newly diagnosed myeloma who could not have a transplant because of their age or physical condition received either three drugs (daratumumab, lenalidomide and dexamethasone) or two drugs (lenalidomide and dexamethasone). Adding daratumumab almost doubled the time the disease stayed under control (about 62 months versus 34 months), and after five years about two thirds of patients in this group were alive, compared with about half in the other group. This benefit was also seen in older people, even those over 80, and no new side effects were reported.

Doses follow the trial protocol, guideline or official drug label (source given in the notes of each regimen). Before prescribing, check blood counts, renal and hepatic function, drug interactions and the patient’s condition, and adjust the dose according to the drug label.

Treatment arms and regimens

1Daratumumab + lenalidomide + dexamethasone (D-Rd)

28-day cycles until disease progression or unacceptable toxicity: daratumumab 16 mg/kg IV weekly in cycles 1 and 2, every 2 weeks in cycles 3 to 6 and then every 4 weeks; lenalidomide 25 mg orally on days 1 to 21; dexamethasone 40 mg weekly (20 mg in patients over 75 years or with BMI below 18.5). After a protocol amendment, switching to subcutaneous daratumumab was allowed.

2Lenalidomide + dexamethasone (Rd)

Lenalidomide 25 mg orally on days 1 to 21 and dexamethasone 40 mg weekly in 28-day cycles until disease progression or unacceptable toxicity.

Source of the regimen details: ClinicalTrials.gov NCT02252172 and the FDA label for DARZALEX (Clinical Studies section, MAIA)

Doses are given for the information of specialists, as in this study’s protocol, and are not a prescription. Every drug must be prescribed by the treating physician for the individual patient.

Study population

Patients with newly diagnosed multiple myeloma (NDMM) who were ineligible for stem-cell transplantation. This report includes subgroup analyses by age (under 70, 70 to under 75, 75 and older, and 80 years and older).

Endpoints

Primary endpoint: progression-free survival (PFS).

Other endpoints: overall survival, complete response or better, minimal residual disease (MRD) negativity and sustained MRD negativity, and safety; plus age-subgroup analyses.

Safety and side effects

According to the abstract, no new safety concerns were observed with this longer follow-up. Adverse event figures are given in the full text of the paper.

Clinical significance and place in guidelines

This long-term analysis confirms the benefit of D-Rd in progression-free and overall survival in transplant-ineligible patients and shows its benefit across all age groups, including 80 years and older. According to the authors, these results continue to support D-Rd as first-line therapy in this group.

Limitations

This report is an updated analysis of the trial, and the age-subgroup analyses are descriptive. The abstract does not give details of adverse events or doses. The comparator was the two-drug Rd regimen, not newer three-‎ or four-drug regimens.
