Clinical Trial Summary

Lurbinectedin is mainly eliminated by the liver. Thus, Hepatic Impairment (HI) may alter the plasma concentrations of lurbinectedin. This study is designed to examine the PK and safety of an adjusted dose of lurbinectedin when administered to patients with HI. The results of this study may be used to support future clinical studies in patients and prescribing information in future labeling.

Description:

This is a prospective, open-label, parallel, phase Ib, hepatic impairment study in patients with advanced solid tumors who either have Hepatic Impairment (HI) at varying degrees (mild, moderate or severe) or qualify for the control group (normal hepatic function) according to the National Cancer Institute Organ Dysfunction Working Group (NCI-ODWG) classification criteria of HI.

Intervention

Drug:
• Lurbinectedin
Patients will receive lurbinectedin as a 1-hour (-5/+20 min) i.v. infusion on Day 1 every three weeks (q3wk), over a minimum of 100 mL dilution on 5% glucose or 0.9% sodium chloride via a central line (or a minimum of 250 mL dilution if a peripheral line is used). Of note, Cycle 2 or subsequent will be administered every q3wk (+ 48 hours). Patients will receive a maximum of two cycles: a first mandatory cycle with all study assessments followed by a second optional cycle with lurbinectedin (this last optional for patients with clinical benefit as per Investigator's criteria). After completing Cycle 2, those patients waiting for the compassionate use approval will continue on the study receiving lurbinectedin herein after until disease progression, unacceptable toxicity, consent withdrawal or while it is considered to be in their best interest, or until starting treatment with lurbinectedin under a Compassionate Use Agreement outside this study. Lurbinectedin at a 3.2 mg/m² dose.
