Multicenter Randomized Controlled Trial

Background: Doxycycline was demonstrated in a retrospective study to be associated with greater survival in patients with light chain (AL) amyloidosis. Therefore, we prospectively compared the efficacy of bortezomib-cyclophosphamide-dexamethasone (CyBorD) and CyBorD combined with doxycycline for cardiac AL amyloidosis. Methods: This was a multicenter, open-label randomized controlled trial. Patients with Mayo 2004 stage II-III AL amyloidosis were included. Patients were randomized to doxycycline 100 mg twice daily along with 9 cycles of CyBorD (doxycycline group) or to 9 cycles of CyBorD alone (control group). The primary outcome was 2-year progression-free survival (PFS). PFS was defined as the time from randomization to death, hematologic progression or organ progression (heart, kidney or liver). Hematologic progression was defined based on substantial increase in free light chain. Increase in either N-terminal pro B-type natriuretic peptide or cardiac troponin was the main criterion for defining cardiac progression. Cardiac PFS, defined as the time from randomization to cardiac progression or death, was compared between groups in an exploratory analysis. The corresponding treatment hazard ratio was estimated using a Cox regression model. Results: 140 patients underwent randomization, with 70 in each group. The median age was 61 (range, 33-78) years with a male: female ratio of 1.75:1. Stage II disease was present in 34 (48.6%) and 33 (47.1%) patients in the doxycycline and control groups, respectively. After a median follow-up duration of 24.4 months, 32/70 (45.7%) of patients in the doxycycline group and 30/70 (42.9%) of patients in the control group experienced progression. PFS was not significantly different between groups (hazard ratio 0.97, 95% CI, 0.59-1.60, p =0.91). Cardiac progression occurred in 29/70 (41.4%) of patients in the doxycycline group and 26/70 (37.1%) of patients in the control group. The death rates for both groups by the end of follow-up was the same, 25/70 (35.7%). There were no significant differences observed for either cardiac PFS (hazard ratio 0.91, 95% CI, 0.54-1.55, p =0.74) or overall survival (hazard ratio 1.04, 95% CI, 0.60-1.81, p =0.89). Conclusions: Our trial demonstrated that doxycycline combined with CyBorD failed to prolong PFS or cardiac PFS compared with CyBorD alone in cardiac AL amyloidosis.
