Conditions
Brief summary
Study to assess the potential effects of lurbinectedin (PM01183) at a therapeutic dose on the duration of the QTc interval, measured by electrocardiograms (ECGs), to characterize the PM01183 plasma concentration/QTc relationship, and to explore related ECG parameters in patients with selected solid tumors.

On Day 1 (D1) of Cycle 1 (C1), LSM ΔQTcF should have low difference values, without any clear trend to change with time. Therefore, the upper bound (UB) of the (two-sided) 90%Confidence Interval (CI) at all time points had to be less than the protocol-specified cut-off of 20 ms at each time point. If so, non-inferiority of any ECG time point to baseline with respect of QTc prolongation could be concluded |

Recruitment details
This study was nested into a multicenter clinical trial with a competitive recruitment. From August 2015 to June 2016, a total of 39 evaluable patients at 12 sites in USA and Spain were included in this QT evaluation study with baseline and one or more postbaseline Electrocardiogram (ECG) assessments available.
Participants by arm
| Arm | Count |
|---|---|
| Group A - Lurbinectedin (PM01183) lurbinectedin (PM01183) is presented as a lyophilized powder for concentrate for solution for infusion with strength of 4 mg / vial.
Lurbinectedin was administered at a dose of 3.2 mg/m² given as a 1-hour i.v. every three weeks (q3wk) (three weeks = one treatment cycle). QTc interval duration was assessed when the patient was treated with lurbinectedin for the first time. | 39 |

Outcome results
Change in QTcF (QT Corrected According to Fridericia's Formula)
ΔQTCF (Change in QTcF); EOI (end of infusion); LSM (Least Square Means); PK (Pharmacokinetic(s)). On Day 1 (D1) of Cycle 1 (C1), LSM ΔQTcF should have low difference values, without any clear trend to change with time. Therefore, the upper bound (UB) of the (two-sided) 90%Confidence Interval (CI) at all time points had to be less than the protocol-specified cut-off of 20 ms at each time point. If so, non-inferiority of any ECG time point to baseline with respect of QTc prolongation could be concluded
