Lurbinectedin, a novel anticancer drug, has been associated with certain side effects that can impact its dosing. According to the available information, the primary side effects that affect lurbinectedin dosing include myelosuppression, particularly neutropenia, and elevated liver enzymes [1].

Neutropenia, a condition characterized by a low count of neutrophils (a type of white blood cell), is a common side effect of lurbinectedin. This side effect can lead to a higher risk of infection, and as a result, the dosing of lurbinectedin may need to be adjusted based on the severity of neutropenia [1]. The drug's summary of product characteristics recommends monitoring neutrophil counts and adjusting the dosage or delaying treatment if necessary [1].

Additionally, lurbinectedin can cause elevations in liver enzymes, such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST). These elevations can indicate liver damage or inflammation. As a result, it is essential to monitor liver function tests regularly during lurbinectedin treatment. If significant elevations in liver enzymes occur, the dosage may need to be modified or treatment may need to be temporarily halted [1].

It is important to note that other factors, such as renal function and patient comorbidities, may also impact lurbinectedin dosing [1]. Healthcare professionals should consider these factors when determining the appropriate dosage for each patient.

In summary, lurbinectedin's side effects, particularly myelosuppression and elevated liver enzymes, can significantly impact its dosing. Regular monitoring of blood cell counts and liver function tests is crucial to ensure safe and effective treatment [1].
