Lurbinectedin is a novel anticancer drug that has shown promising results in the treatment of certain types of cancer, such as small cell lung cancer (SCLC) [1]. However, as with any medication, there are potential risks and side effects associated with its use.

According to the drug's manufacturer, the most common adverse reactions (incidence ≥20%) reported in clinical trials include neutropenia, leukopenia, anemia, thrombocytopenia, increased creatinine, increased alanine aminotransferase (ALT), increased aspartate aminotransferase (AST), fatigue, nausea, vomiting, decreased appetite, and constipation [2].

Moreover, lurbinectedin can cause serious side effects such as severe neutropenia, which can lead to infections that may be life-threatening [2]. Therefore, it is essential to monitor complete blood counts (CBC) regularly during treatment with lurbinectedin.

Additionally, lurbinectedin can cause fetal harm when administered to a pregnant woman. Therefore, it is contraindicated during pregnancy, and women of reproductive potential should use effective contraception during treatment and for at least 6 months after the last dose [2].

It is worth noting that, as of the time of writing, lurbinectedin does not have an approved patent in the United States [3]. However, it is under development by several pharmaceutical companies worldwide, and its patent status may change in the future.

In summary, while lurbinectedin has shown promising results in the treatment of certain types of cancer, it is associated with potential risks and side effects, including severe neutropenia, infections, and fetal harm. Therefore, it is crucial to monitor patients closely during treatment and follow the manufacturer's guidelines carefully.
