About this trial
The purpose of this study is to find out if a drug called lurbinectedin (the "study drug") is safe and effective at treating people with recurrent or relapsed solid tumors, including Ewing sarcoma.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age ≥ 10 years.
Phase 1: Histological confirmed diagnosis of recurrent or relapsed solid tumor failing primary therapy. Patients must have a known FET fusion (fusion that contains EWSR1, FUS, or TAF15) as documented by next generation sequencing, polymerase chain reaction (PCR) or Fluorescence in situ hybridization (FISH). Patients with a histological diagnosis of Ewing sarcoma with EWS-FLI1 are eligible for dose escalation but not for the exploratory cohort. Please note patients with Ewing sarcoma and alternative FET-ETS fusions (including but not limited to EWS-ERG, EWS-ETV1, EWS-ETV4, EWS-FEV, FUS-ERG, FUS-FEV) are eligible for the exploratory cohort.
Phase 2: Histologically confirmed diagnosis of recurrent or relapsed Ewing sarcoma failing primary therapy with confirmation of EWS-FLI1 fusion and breakpoint by Next generation sequencing or PCR or EWSR1 rearrangement confirmed by FISH and available tissue for central confirmation of EWS-FLI1 fusion and breakpoint.
Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1 (age >16 years) or Lansky of at least 70 (age <16 years).
Disqualifiers
Prior therapy with trabectedin or lurbinectedin.
Subjects with known brain metastases.
Subjects with a known bleeding diathesis.
Subjects who are pregnant or breastfeeding.

Treatment groups
Trial outcomes
Primary outcomes
Phase 1: Dose Limiting Toxicities (DLTs)
First cycle (approximately 21 days) Dose Limiting Toxicities (DLTs) will be evaluated.
Phase 1: Frequency of adverse events
Adverse events to be reported during treatment and for at least 28 days after last dose.
Phase 1: Complete Response or Partial Response
Percentage of participants with complete response or partial response will be assessed approximately every 2 to 4 cycles through the end of treatment and up to at least 28 days after the last dose.
Phase 2: Event-Free Survival (EFS)
Event-free survival (EFS) is based on investigator assessment from baseline until Month 24.
Secondary outcomes
Phase 1: Maximum observed Plasma Concentration (Cmax)
Maximum observed plasma concentration (Cmax) will be used to assess Lurbinectedin Pharmacokinetics
Phase 1: Area under the concentration-time curve (AUC)
Area under the concentration-time curve (AUC) will be used to assess Lurbinectedin Pharmacokinetics
Phase 2: 6-month Progression Free Survival (PFS)
Progression Free Survival (PFS) assessed from the first dose of study drug to earliest date of death or progressive disease.
Phase 1: Duration of Response (DoR)
Duration of Response (DoR) defined as time from date of first response (Complete Response or Partial Response) in responders to date of progression or death
