Abstract:
Hand-foot skin reaction (HFSR) is the most debilitating and prevalent side effect caused by multikinase inhibitors (MKIs) that share vascular endothelial growth factor receptor (VEGFR) as the common inhibition target, such as sorafenib, regorafenib, axitinib, etc. Though not life-threatening, HFSR can significantly deteriorate patients' quality of life and jeopardize the continuity of cancer therapy. Despite years of efforts, there are no FDA-approved treatments for HFSR and the understanding of the precise pathogenic mechanism is still limited. In this study, we hypothesized that nitric oxide has the potential therapeutic effect to reverse the toxicity caused by MKI through upregulation of several VEGF/VEGFR downstream signaling pathways. We found that glyceryl trinitrate (GTN), a nitric oxide donor, could stimulate cell proliferation, migration, and protect cells from apoptosis induced by MKIs in vitro. Local application of GTN mitigated tissue damage in a rat model, while not impacting the anti-tumor effect of the MKI in HepG2 tumor-bearing mice. Finally, GTN ointment alleviated cutaneous damages and improved quality of life in 6 HFSR patients. Our study proposed and validated the mechanism to counteract VEGFR inhibition, providing GTN as the potential treatment to MKI-induced HFSR, which may further improve the therapeutic window of various MKI based cancer therapies.
Insights
Glyceryl trinitrate (GTN), a nitric oxide donor, effectively treats hand-foot skin reaction (HFSR) caused by multikinase inhibitors (MKIs). This study shows GTN mitigates HFSR symptoms and improves patient quality of life without compromising anti-cancer effects.
Area of Science:
- Oncology
- Dermatology
- Pharmacology
Background:
- Hand-foot skin reaction (HFSR) is a common, debilitating side effect of multikinase inhibitors (MKIs) targeting vascular endothelial growth factor receptor (VEGFR).
- Current treatments for HFSR are lacking, and its precise pathogenic mechanisms remain unclear, impacting cancer therapy continuation and patient quality of life.
- Nitric oxide (NO) signaling pathways are implicated in cellular processes affected by VEGFR inhibition.
Purpose of the Study:
- To investigate the therapeutic potential of nitric oxide, specifically glyceryl trinitrate (GTN), in mitigating MKI-induced HFSR.
- To elucidate the underlying mechanisms by which NO may counteract VEGFR inhibition-related toxicities.
- To evaluate the efficacy and safety of topical GTN in preclinical models and human patients with HFSR.
Main Methods:
- In vitro studies using cell cultures to assess GTN's effects on proliferation, migration, and apoptosis induced by MKIs.
- Preclinical testing in a rat model to evaluate GTN's impact on tissue damage.
- In vivo efficacy study in HepG2 tumor-bearing mice to assess GTN's effect on MKI anti-tumor activity.
- Clinical trial involving HFSR patients treated with GTN ointment.
Main Results:
- In vitro, GTN demonstrated protective effects against MKI-induced cellular toxicity, promoting cell proliferation and migration while reducing apoptosis.
- Local GTN application in rats significantly mitigated tissue damage associated with MKI treatment.
- In mice, GTN did not interfere with the anti-tumor efficacy of MKIs.
- Topical GTN treatment in HFSR patients led to alleviation of cutaneous symptoms and improved quality of life.
Conclusions:
- Nitric oxide, delivered via glyceryl trinitrate, represents a promising therapeutic strategy for managing MKI-induced hand-foot skin reaction.
- GTN counteracts VEGFR inhibition toxicity by upregulating downstream signaling pathways, offering a novel mechanism for HFSR treatment.
- The findings support GTN as a potential adjunct therapy to improve the tolerability and therapeutic window of MKI-based cancer treatments.

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
