Learning objective: After reading this article, learners will be able to cite a new clinical development in acute lymphoblastic leukemia.


 

Vincristine, a vinca alkaloid used in the treatment of ALL, is known to cause peripheral neuropathy.1 Evidence shows curcumin can effectively prevent the development of several neurological conditions.1

Results from a single center phase III clinical trial (IRCT20201107049296N3) evaluating the effectiveness of oral curcumin in preventing the development of vincristine-induced peripheral neuropathy (VIPN) in pediatric patients with ALL were published by Eghbali et al.1 in BMC Cancer Eligible patients were randomized to receive curcumin (n = 74) or placebo (n = 74). The primary endpoint was the occurrence of VIPN.1

 

Key learnings

Among 141 evaluable patients, VIPN occurred in 42.6% vs 66.4% of patients based on TNS-PV, 62.1% vs 82.5% of patients based on NCS, and 17.0% vs 54.0% of patients based on EMG in the curcumin vs placebo group, respectively.
Overall, patients in the curcumin group experienced a lower incidence of VIPN vs those in the placebo group (39.4% vs 70.0%; p < 0.001).
The frequency of motor nerve (p = 0.012) and sensory nerve (p = 0.440) abnormalities were lower in the curcumin vs placebo group.
These findings show that curcumin improved VIPN, reduced motor nerve abnormalities, and was effective in preventing the development of VIPN in pediatric patients with ALL. Curcumin may therefore represent a promising adjunct therapy for mitigating chemotherapy induced neuropathy.
