Abstract:
Gastric cancer (GC) is the fifth most common malignancy and the third cause of cancer-related deaths worldwide. Currently, surgery and chemotherapy remain the main therapeutic options and the prognosis of the disease is still poor in the metastatic setting. Avelumab is a human IgG1 antibody directed against PD-L1 approved for Merkel cell carcinoma and urothelial carcinoma that could be useful also for the treatment of GC. This review describes the chemical structure, the pharmacologic properties and the current knowledge of the efficacy of avelumab in the treatment of GC from the data available on the first and later phase clinical trials. The ongoing studies testing this drug either alone or in combination with other drugs are also described.
Insights
Avelumab, an anti-PD-L1 antibody, shows potential for treating gastric cancer (GC). This review covers its properties, efficacy in clinical trials, and ongoing research for GC treatment.
Area of Science:
- Oncology
- Immunotherapy
- Gastroenterology
Background:
- Gastric cancer (GC) is a leading cause of cancer death globally, with poor prognosis in metastatic stages.
- Current treatments like surgery and chemotherapy have limitations for advanced GC.
- Avelumab, an anti-PD-L1 antibody, is approved for other cancers and is being investigated for GC.
Purpose of the Study:
- To review the chemical structure and pharmacologic properties of avelumab.
- To summarize the current efficacy data of avelumab in gastric cancer treatment from clinical trials.
- To describe ongoing studies evaluating avelumab in GC, alone or in combination therapies.
Main Methods:
- Literature review of published data on avelumab.
- Analysis of clinical trial results (Phase I, II, and ongoing) for gastric cancer treatment.
- Examination of avelumab's mechanism of action and pharmacological profile.
Main Results:
- Avelumab's structure and properties relevant to cancer therapy are detailed.
- Clinical trial data on avelumab's efficacy in gastric cancer is presented.
- Ongoing trials exploring avelumab's use in various GC settings are highlighted.
Conclusions:
- Avelumab demonstrates potential as a therapeutic option for gastric cancer.
- Further clinical investigation is warranted to establish its role in GC treatment.
- Combination strategies involving avelumab may offer improved outcomes for GC patients.
