Based on the information available, there is a potential risk of toxicity when using lurbinectedin in combination with other drugs. Lurbinectedin is a selective inhibitor of oncogenic transcription, and it has been approved for the treatment of metastatic small cell lung cancer (sCLC) in adults [1]. However, like many other cancer treatments, lurbinectedin can cause side effects, some of which can be severe or life-threatening [1].

When using lurbinectedin in combination with other drugs, the risk of toxicity may increase due to the potential additive or synergistic effects of the medications [2]. The severity of the toxicity will depend on several factors, including the dosage of the drugs, the duration of treatment, the patient's overall health, and the presence of other medical conditions [2].

It is important to note that the risk of toxicity associated with lurbinectedin combinations may vary depending on the specific drugs being used. For example, a study published in the Journal of Clinical Oncology found that the combination of lurbinectedin and doxorubicin was associated with a high rate of severe adverse events, including neutropenia, febrile neutropenia, and thrombocytopenia [3]. However, the study also noted that the combination showed promising antitumor activity in patients with relapsed small cell lung cancer [3].

To minimize the risk of toxicity, healthcare providers should closely monitor patients receiving lurbinectedin combinations for signs of adverse events [2]. This may include regular blood tests to assess blood cell counts, liver function, and other markers of toxicity [2]. Patients should also be advised to report any symptoms or side effects promptly to their healthcare provider [2].

In summary, while lurbinectedin can be an effective treatment for metastatic small cell lung cancer, there is a potential risk of toxicity when using lurbinectedin combinations. Healthcare providers should carefully monitor patients receiving these treatments to minimize the risk of adverse events.
