Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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.

Official Title

A Phase 1/2, Open-label Study to Evaluate the Safety, Tolerability, Pharmacokinetics (PK), Recommended Phase 2 Dose (RP2D), and Efficacy of Lurbinectedin Monotherapy in Pediatric Participants With Previously Treated Solid Tumors Followed by Expansion to Assess Efficacy and Safety in Pediatric and Young Adult Participants With Relapsed/Refractory Ewing Sarcoma.

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.

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. * Received prior treatment with lurbinectedin or trabectedin. * Received prior treatment with any investigational product within 4 weeks of first infusion of study intervention. Observational studies are permitted. * Received live or live attenuated vaccines within 4 weeks of the first dose of study treatment or plans to receive live vaccines during study participation. Administration of inactive vaccines or messenger ribonucleic acid (mRNA) vaccines (for example, inactivated influenza vaccines or COVID-19 vaccines) are allowed. * Had major surgery ≤ 4 weeks or radiation therapy ≤ 2 weeks prior to enrollment unless fully recovered. Prior palliative radiotherapy is permitted, provided it was completed at least 2 weeks prior to participant enrollment. * Received prior allogeneic bone marrow transplantation or solid organ transplant. * Received chemotherapy ≤ 3 weeks prior to start of study intervention. * Hepatitis B virus (HBV) or Hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or Polymerase chain reaction (PCR) test for HCV RNA if HCV antibody test is positive). * Human immunodeficiency infection at screening (positive anti-HIV antibody). * Has a known or suspected hypersensitivity to any of the components of the study intervention. * The participant or parent(s)/guardian(s) is/are unable to comply with the study visit schedule and other protocol requirements, in the opinion of the investigator
