Navelbine® (vinorelbine)


Navelbine® (vinorelbine) is a chemotherapy medication classified as a vinca alkaloid, derived originally from the periwinkle plant. It operates by targeting microtubules, essential components of the cell structure necessary for cellular growth and division. This action interferes with cancer cell growth and division, making it an option for cancer treatment, including mesothelioma.

In the context of mesothelioma, a rare and aggressive form of cancer primarily affecting the lining of the lungs (pleura), vinorelbine is not a frontline treatment but can be considered for certain patients. It may be especially relevant for those who have not responded well to first-line treatment options. Doctors may decide to use vinorelbine based on its potential to inhibit cell division by targeting specific proteins and its ability to interfere with DNA and RNA synthesis, thereby potentially causing cancer cell death and inhibiting growth.

Vinorelbine’s effectiveness increases when used in combination with other chemotherapy drugs, such as cisplatin, due to the different mechanisms these drugs use to target and kill fast-dividing cancer cells. This combination strategy aims to enhance the overall efficacy of the treatment, increasing the chances of eliminating cancer cells.

For pleural mesothelioma specifically, vinorelbine has been explored in various capacities, including as a first-line treatment (alone or in combination with other drugs) and as a second-line treatment for patients who may not be eligible for more conventional treatments or clinical trials. The outcomes from studies involving vinorelbine for pleural mesothelioma have shown median survival times ranging from approximately 6 to 17 months, indicating a potential benefit in certain cases, especially when combined with standard chemotherapy treatments.

Despite its exploration in mesothelioma treatment, vinorelbine is officially approved by the U.S. Food and Drug Administration (FDA) only for the treatment of non-small cell lung cancer (NSCLC). However, its usage extends into studies and treatments for other cancers, including breast cancer, cervical cancer, Hodgkin lymphoma, mesothelioma, and multiple myeloma, underlining its potential versatility as a cancer treatment option.

In summary, while not commonly used for mesothelioma, vinorelbine represents a potential treatment avenue for certain patients, particularly those who have not had success with other treatments. The decision to use vinorelbine is typically made by mesothelioma doctors based on the individual patient’s situation and the drug’s mechanism of action and potential benefits in combating cancer cell growth.
