Are there weight based dosages for lurbinectedin?

Lurbinectedin dosing starts at 3.2 mg/m² given as a 60-minute infusion every three weeks. This calculation already incorporates body surface area, which itself draws from a patient’s height and weight.

Lurbinectedin has no fixed-weight or mg/kg schedule. All clinical studies and the prescribing information use surface-area dosing.

What happens if a patient gains or loses weight?
Patients keep the same 3.2 mg/m² dose even if their body surface area changes modestly.
