What was measured
QALYs were estimated with a model beginning at initiation of first-line therapy by arm. A lifetime horizon, as well as subsequent lines of therapy, was examined using open-source Amua 0.3.0 software. Base case analysis was performed using 10,000 first-order Monte Carlo simulations. Conditional probabilities were extracted from Kaplan-Meier curves from pivotal clinical trials using WebPlotDigitizer. Costs were estimated from RED BOOK and DFCI charge reporting in US Dollars ($) after inflation adjustment to 2022 and 3% discounting, and QALYs effects were measured using EQ-5D data from Hatswell et al.
Groups in this outcome
RVD Alone
All participants received one cycle of Lenalidomide (R), bortezomib (V) and dexamethasone (D) and then were randomized. All participants then received two additional RVD cycles, followed by stem-cell collection. RVD Alone participants received five additional RVD cycles. Maintenance in both arms comprised daily lenalidomide 10 mg, escalated to 15 mg if tolerated, until disease progression, unacceptable toxicity, or withdrawal from treatment or study. After finishing protocol-specified treatment, off-study salvage transplantation was recommended but not mandated for RVD Alone participants at relapse. RVD cycle duration=21 days R: 25 mg oral on days 1-14 V: 1.3 mg per square meter of body surface area IV or subcutaneous on days 1, 4, 8, and 11 D: 20 mg oral (cycles 1-3) or 10 mg (cycles 4-8) on days 1, 2, 4, 5, 8, 9, 11, and 12
RVD Plus ASCT
All participants received one cycle of Lenalidomide (R), bortezomib (V) and dexamethasone (d) and then were randomized. All participants then received two additional RVD cycles, followed by stem-cell collection. RVD plus autologous stem cell transplant (ASCT) participants received high-dose melphalan (200 mg/m2, adjusted for ideal body weight) ASCT and, upon recovery (\~day 60), two additional RVD cycles. Maintenance in both arms comprised daily lenalidomide 10 mg, escalated to 15 mg if tolerated, until disease progression, unacceptable toxicity, or withdrawal from treatment or study. After finishing protocol-specified treatment, RVD plus ASCT participants could undergo a second transplant. RVD cycle duration=21 days R: 25 mg oral on days 1-14 V: 1.3 mg per square meter of body surface area IV or subcutaneous on days 1, 4, 8, and 11 D: 20 mg oral (cycles 1-3) or 10 mg (cycles 4-8) on days 1, 2, 4, 5, 8, 9, 11, and 12
