In plain words

In this study, patients with multiple myeloma received either the RVD drugs alone or the same drugs together with a transplant of their own stem cells. Patients who had a transplant stayed free of disease progression for longer, but overall survival after 4 years was about the same in the two groups. The transplant came with side effects such as a deeper fall in white blood cells, bowel and stomach problems and infections. The decision about a transplant should be made with the treating doctor, taking each patient's circumstances into account.

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

1RVD-alone group

Induction: three 21-day cycles of RVD comprising lenalidomide 25 mg orally on days 1 to 14, bortezomib 1.3 mg/m² IV on days 1, 4, 8 and 11 and dexamethasone 20 mg orally on days 1, 2, 4, 5, 8, 9, 11 and 12; then stem cell collection with cyclophosphamide and G-CSF. Consolidation: five more cycles of RVD with the daily dexamethasone dose reduced to 10 mg (8 cycles in total; 350 patients). Maintenance: lenalidomide 10 mg daily for the first 3 months and 15 mg if tolerated, starting within 3 weeks after consolidation, for 1 year.

2RVD plus transplantation group

Induction: three cycles of RVD at the same doses and stem cell collection with cyclophosphamide and G-CSF; then melphalan 200 mg/m² and autologous stem cell transplantation; then two cycles of RVD with dexamethasone 10 mg (350 patients). Maintenance: lenalidomide 10 mg daily for the first 3 months and 15 mg if tolerated, for 1 year.

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 aged 65 years or younger with symptomatic, measurable, newly diagnosed multiple myeloma.

Endpoints

Primary endpoint: progression-free survival (PFS). The abstract also reports complete response, absence of minimal residual disease (MRD) and overall survival.

Safety and side effects

Grade 3 or 4 neutropenia: 92% in the transplant group versus 47% in the RVD-alone group. Grade 3 or 4 gastrointestinal disorders: 28% versus 7%. Infections: 20% versus 9%. There was no significant difference between the two groups in treatment-related deaths, second primary cancers, thromboembolic events or peripheral neuropathy.

Clinical significance and place in guidelines

This study showed that adding transplantation to RVD prolongs progression-free survival, but in this report overall survival did not differ and grade 3 or 4 adverse events were more frequent. The abstract gives no information on the impact on guidelines or approvals; the current status of guideline recommendations should be checked separately.

Limitations

Based on the abstract, the difference in overall survival at 4 years was not significant, and longer follow-up may be needed. Other limitations should be checked in the full text of the paper.
