Abstract
PURPOSE
Pegylated liposomal doxorubicin (PLD) is highly effective for treating multiple myeloma (MM). Hand-foot syndrome (HFS) is a dose-limiting adverse event of PLD that may reduce a patient's quality of life or prevent certain patients from receiving PLD. Several researchers have discovered that pyridoxine, an activated form of vitamin B6, may prevent PLD-associated HFS. We designed a prospective randomized trial to examine whether prophylactic pyridoxine might prevent the incidence or delay the occurrence of PLD-induced HFS in patients with MM.
METHODS
Patients who met the trial's eligibility requirements were randomized and then administered either pyridoxine 100 mg twice daily or no pyridoxine, in both cases accompanied by their PLD-containing chemotherapeutic agent. Follow-up of patients was performed until the completion of induction therapy, the development of HFS or disease progression.
RESULTS
Between January 1, 2017, and January 1, 2019, 105 patients were randomly assigned to the pyridoxine group (n = 52) or the no pyridoxine group (n = 53). In the pyridoxine and no pyridoxine groups, HFS developed after a median of 4 (range, 1-8 cycles) and 3 (range, 1-7 cycles) chemotherapeutic cycles, respectively. There were no grade 3 incidents recorded. Overall, 13.3% of patients experienced HFS. A 11 of 53 (20.8%) patients in the no pyridoxine group experienced HFS, compared to 3 of 52 (5.8%) patients in the pyridoxine group (P = .042); there was no difference in HFS grades (P = .725).
CONCLUSIONS
The findings of benefit from prophylactic pyridoxine in this open-label trial have suggested its promise as a treatment for reducing HFS in MM patients. Further research with a placebo-controlled design is recommended.
