Abstract:
The AXL receptor tyrosine kinase is a transmembrane protein commonly overexpressed in both solid and hematologic malignancies. AXL plays a role in malignant cell growth, survival, proliferation, and adaptive immunity. As such, AXL overexpression is correlated with a worse prognosis. Drugs impairing the function of AXL are currently in development as monotherapies and in combination with other agents and have displayed antitumor efficacy in preclinical models, including tumors with AXL overexpression. AXL inhibitors have demonstrated preliminary antitumor activity in clinical trials and have generally been well tolerated, with the most common side effects including neutropenia, diarrhea, fatigue, nausea, and anemia. This clinical review aims to provide a comprehensive summary of published information from clinical trials investigating AXL inhibitors as monotherapies or in combination regimens.
Insights
AXL receptor tyrosine kinase inhibitors show promise in treating cancers with AXL overexpression. These AXL inhibitors are well-tolerated and demonstrate antitumor activity in clinical trials.
Area of Science:
- Oncology
- Molecular Biology
- Drug Development
Background:
- AXL receptor tyrosine kinase is overexpressed in various cancers, correlating with poor prognosis.
- AXL signaling drives malignant cell growth, survival, proliferation, and impacts adaptive immunity.
Purpose of the Study:
- To comprehensively review clinical trials on AXL inhibitors.
- To summarize their efficacy as monotherapies and in combination regimens.
Main Methods:
- Systematic review of published clinical trial data.
- Analysis of efficacy and safety profiles of AXL inhibitors.
Main Results:
- AXL inhibitors show preliminary antitumor activity in clinical trials.
- These agents are generally well-tolerated, with common side effects like neutropenia, diarrhea, fatigue, nausea, and anemia.
Conclusions:
- AXL inhibitors represent a promising therapeutic strategy for cancers with AXL overexpression.
- Further investigation in monotherapy and combination settings is warranted.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
