简要总结
This study is conducted in two phases. The phase 1 portion of the study evaluates the safety, tolerability, pharmacokinetics (PK), recommended phase 2 dose (RP2D), and effectiveness of lurbinectedin monotherapy in pediatric participants with previously treated solid tumors. This is followed by the phase 2 portion, to further assess the effectiveness and safety in pediatric and young adult participants with recurrent/refractory Ewing sarcoma.

- •Male participants are eligible to participate if they agree to the following during the study intervention period and for at least 4 months after the last dose of study intervention:
- •Refrain from donating sperm.
- •PLUS, either:
- •Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent.
- •Must agree to use contraception/barrier as detailed below:
- •Agree to use a male condom with female partner and use of an additional highly effective contraceptive method with a failure rate of < 1% per year when having sexual intercourse with a Woman of childbearing potential (WOCBP) who is not currently pregnant.
- •Note: male participants who are azoospermic (vasectomized or due to a medical cause) are still required to follow the protocol-specified contraception/barrier criteria.
- •Female participants:
- •A female participant is eligible to participate if she is not pregnant or breastfeeding, and one of the following conditions applies:
- •Is a Woman of nonchildbearing potential (WONCBP). OR
- •Is a WOCBP and using an acceptable contraceptive method during the study intervention period (at least 7 months after the last dose of study intervention). The investigator should evaluate the potential for contraceptive method failure (eg, noncompliance, recently initiated) in relationship to the first dose of study intervention.
- •A WOCBP must have a negative highly sensitive pregnancy test (urine or serum as required by local regulations) within 7 days before the first dose of study intervention.
- •If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive.

Participants with previously diagnosed CNS metastases are eligible if they have completed their treatment and have recovered from the acute effects of radiation therapy or surgery prior to enrollment, have discontinued high dose steroid treatment for these metastases for at least 2 weeks, and are neurologically stable (physiologic doses of steroids and short courses of steroids for other indications are acceptable).
- •Persisting toxicity related to prior therapy; however, alopecia, sensory neuropathy, hypothyroidism, and rash Grade ≤ 2 are acceptable, and other Grade ≤ 2 adverse events (AEs) not constituting a safety risk based on the investigator's judgement are acceptable.
- •An uncontrolled intercurrent illness including but not limited to ongoing or active infection requiring antibiotic, antifungal, or antiviral therapy, symptomatic heart failure, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
- •Any other major illness that, in the investigator's judgment, could substantially increase the risk associated with participation in this study.
- •Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or that may affect the interpretation of the results or render the participant at high-risk for treatment complications.

研究组 & 干预措施
Phase 1 Part 1: Dose Selection
Experimental
Pediatric 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.
干预措施: Lurbinectedin (Drug)
Phase 1 Part 2: RP2D
Experimental
Participants aged ≥ 2 to ≤ 30 years with recurrent/refractory Ewing sarcoma at the RP2D to assess safety and efficacy signals.
干预措施: Lurbinectedin (Drug)
Phase 2
Experimental
If 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.
干预措施: Lurbinectedin (Drug)
