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 volunteers

Qualifiers

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.

within 28 days of the first dose
2

Phase 1: Frequency of adverse events

Adverse events to be reported during treatment and for at least 28 days after last dose.

Time frame
28 days after last dose
3

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.

Time frame
through the end of treatment, an average of 1 year
4

Phase 2: Event-Free Survival (EFS)

Event-free survival (EFS) is based on investigator assessment from baseline until Month 24.

Time frame

Time frame
6 months
4

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

Time frame
