Study Endpoints

Primary Endpoints

Randomized Phase: Independent Review Facility (IRF) - Assessed Progression Free Survival (PFS)
Up to 26 months

PFS was defined as the time from randomization to the date of first documented PD as determined by the IRF according to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1) or death, whichever occurs first. PD was defined as appearance of a new lesion(s), unequivocal progression in non-target lesion(s) or at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest sum on the study including baseline (nadir). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimetres (mm).

Randomized Phase: Overall Survival (OS)
Up to 26 months

OS was defined as the time from randomization to the date of death from any cause.

Evaluate the antitumor activity
Initiation of study treatment up to 10 cycles (each cycle is 21 days ± 48 hours)

To evaluate the antitumor activity of Lurbinectedin in terms of overall response rate (ORR), according to RECIST v.1.1, in patients with advanced pancreatic cancer with DNA repair mutations.

Investigator assessed PFS rate
6 months

Progression Free Survival (PFS) rate is the proportion of participants who have not experienced disease progression (as determined by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1) or death from any cause

Incidence of adverse events of palliative radio therapy (RT) with lurbinectedin
Up to 1 year

Will be defined as having one or none of the following: * Grade 4 or 5 serious adverse events possibly, probably, or definitely related to protocol treatment from 30 days from the start of RT. * Any adverse events possibly, probably, or definitely related to protocol treatment that leads to prolonged dose delays (defined as with-holding of two consecutive doses of lurbinectedin). * Any adverse event possibly, probably, or definitely related to treatment resulting in the permanent discontinuation of lurbinectedin. Will be analyzed separately for safety cohorts 1 and 2 and will be summarized descriptively using frequencies and percentages. These will be compared to rates reported by Trigo et al. from lurbinectedin monotherapy.

Grade 3 or dose-limiting toxicities
Within 30 days after your last dose of study treatment.

The number of incidences of grade 3 or dose-limiting toxicities of the combination of lurbinectedin with osimertinib assessed using NCI CTCAE v5.0 criteria.

Phase 1: Number of Participants Experiencing Dose-limiting Toxicities (DLTs)
From the first dose through end of Cycle 1 (21 days).
Phase 1: Number of Participants Experiencing Serious Adverse Events (SAEs) and Treatment Emergent Adverse Events (TEAEs)
Post-baseline (Day 1) up to approximately 31 months.
Phase 1: Number of Participants With Dose Modifications

Phase 1: Number of Participants Who Discontinued Study Intervention Due to TEAEs
Post-baseline (Day 1) up to approximately 31 months.
Phase 2: Objective Response Rate (ORR) Based on Investigator Assessment (IA)
Day -28 up to a total of 13 months postdose.

Treatment Arms

ArmTypeDescription
Arm A: Atezolizumab+LurbinectedinEXPERIMENTALInduction phase: participants will receive standard of care atezolizumab on Day 1 of each 21-day cycle in combination with carboplatin on Day 1 and etoposide on Days 1, 2, and 3 of each 21-day cycle for 4 cycles. Maintenance phase: participants will receive atezolizumab on Day 1 of each 21-day cycle in combination with lurbinectedin on Day 1 of each 21-day cycle.
Arm B: AtezolizumabACTIVE_COMPARATORInduction phase: participants will receive standard of care atezolizumab on Day 1 of each 21-day cycle in combination with carboplatin on Day 1 and etoposide on Days 1, 2, and 3 of each 21-day cycle for 4 cycles. Maintenance phase: participants will receive atezolizumab on Day 1 of each 21-day cycle.
LurbinectedinEXPERIMENTALLurbinectedin will be administered intravenously (IV) as a 1-hour (±10 min) infusion on Day 1 of each cycle (one cycle = 3 weeks ± 48 hours).
Durvalumab and lurbinectedin treatment armEXPERIMENTALDurvalumab taken in combination with lurbinectedin in participants with ES-SCLC after first line induction therapy with durvalumab and platinum plus etoposide containing regimen.
Treatment (lurbinectedin and palliative radiation therapy)EXPERIMENTALPatients undergo palliative RT over 5 or 10 treatment fractions at the discretion of the treating physician daily for 21 days. Patients also receive lurbinectedin IV over 1 hour on day 1 of each cycle. Cycles of lurbinectedin repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Phase I Does De-EscalationEXPERIMENTAL3.2 mg/m2 or 2.6 mg/m2 dose of lurbinectedin with 80 mg or 40 mg daily dose of osimertinib. This will occur day 1 of each 21 day cycle.
Phase II Dose ExpansionEXPERIMENTAL3.2 mg/m2 or 2.6 mg/m2 dose of lurbinectedin with 80 mg or 40 mg daily dose of osimertinib. This will occur day 1 of each 21 day cycle.
Phase 1 Part 1: Dose SelectionEXPERIMENTALPediatric participants ≥ 2 to \< 18 years of age with previously treated solid tumors of any histology at 5 dose levels to determine the RP2D, followed by a safety expansion cohort. Participants aged ≥ 6 to \< 18 years will be enrolled at the starting dose of 3.2 mg/m\^2 lurbinectedin. If, after review, the starting dose of 3.2 mg/m\^2 lurbinectedin Q3W is deemed safe in participants aged ≥ 6 to \< 18 years, participants aged ≥ 2 to \< 6 years may enroll and start at the dose as determined by the DMC. After this, the study opens to all participants (aged ≥ 2 to \< 18 years) for all dose levels. Upon completion of the cohort at all dose levels, participants may be eligible to enroll in a safety expansion cohort.
Phase 1 Part 2: RP2DEXPERIMENTALParticipants aged ≥ 2 to ≤ 30 years with recurrent/refractory Ewing sarcoma at the RP2D to assess safety and efficacy signals.
Phase 2EXPERIMENTALIf a signal of efficacy is observed in Phase 1 Part 2, additional participants aged ≥ 2 to ≤ 30 years with recurrent/refractory Ewing sarcoma will be enrolled. Phase 2 will further assess the safety and efficacy of lurbinectedin monotherapy.
