Study Endpoints
Primary Endpoints
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

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.

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.

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
Post-baseline (Day 1) up to approximately 31 months.
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.
Secondary Endpoints
Duration of response (DOR)
Initiation of study treatment up to study completion, up to 2 years
Clinical benefit
Initiation of study treatment up to study completion, up to 2 years
Measure amount of CA19-9, CEA, or CA125
Initiation of study treatment up to 12 cycles (each cycle is 21 days ± 48 hours)

ArmTypeDescription
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.
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.
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 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.
