About this study
Official title: Phase II Study of Lurbinectedin and Irinotecan in Adult and Young Adult Patients With Advanced Desmoplastic Small Round Cell Tumor (DSRCT)
Patients participating in this study have DSRCT that has spread locally or to other parts of the body and can no longer be surgically removed without causing significant harm.
Treatment will continue until the tumor progresses further, severe side effects occur, or either patient or investigator decision.
In addition, patients may participate in an optional biological study. The study will analyze the tumor's genes and the molecules related to them. By studying genes and their products, the investigators can better understand the behavior of the tumor and how the body responds to therapies.
Read the detailed description
This is an Italian and Spanish multicentric, prospective, phase II single-arm, open-label, investigator-initiated clinical study that will be conducted within the Italian Sarcoma Group (ISG) and the Spanish Sarcoma Groups (GEIS), aiming at exploring the activity of lurbinectedinin combination with irinotecan, until progression or unacceptable toxicity, in a population of =/>15 years old patients with histologically and molecularly confirmed (EWSR1-WT1 translocation positive), advanced (locally advanced or metastatic) DSRCT, from 2nd to 4th line, following progression to anthracycline-based chemotherapy.
The primary end-point of the study will be the overall response rate (ORR) by RECIST v1.1 in the study population. Secondary end-points will be PFS, DoR, OS, safety and changes in QoL.
Patients will be evaluated for the primary end-point if have completed at least one cycle of lurbinectedin and irinotecan and have at least one post-baseline radiologic disease assessment. Patients with documented early progression disease (PD) or who die due to PD before the first scheduled tumor assessment will also be included in the analysis.
Patients will be followed for follow up visits every 6 months for 2 years.

Adverse events and Serious adverse event (according to CTC-AE v.5)
Measured: After initiation of study treatments(s), all adverse events will be reported until 30 days after the final dose of study treatment or until initiation of new systemic anti-cancer therapy, whichever occurs first.
European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30)
The EORTC QLQ-C30 is a validated 30-item questionnaire assessing health-related quality of life in cancer patients. Scores are linearly transformed to a 0 to 100 scale.
For the Global Health Status/Quality of Life and functional scales (physical, role, emotional, cognitive, and social functioning), higher scores indicate better quality of life or functioning.
For the symptom scales and single-item symptom measures, higher scores indicate greater symptom severity (worse outcome).
Measured: Screening, cycle1 day1 (each cycle is 21 days), cycle2 day1, End Of Treatment visit (performed 30 days after the last study drug administration), at follow-up visits performed at months 6, 12, 18 and 24 after the last study drug administration

Patients participating in this study have DSRCT that has spread locally or to other parts of the body and can no longer be surgically removed without causing significant harm.
Treatment will continue until the tumor progresses further, severe side effects occur, or either patient or investigator decision.
In addition, patients may participate in an optional biological study. The study will analyze the tumor's genes and the molecules related to them. By studying genes and their products, the investigators can better understand the behavior of the tumor and how the body responds to therapies.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Lurbinectedin and Irinotecan in people with Desmoplastic Small Round Cell Tumor, run by Italian Sarcoma Group at 11 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 22 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in Spain, Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Gianluca Ignazzi (+393335359192, gianluca.ignazzi@italiansarcomagroup.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall tumour Response Rate (ORR), according to RECIST v 1.1 (time frame: Week 6, week 12, week 18, week 30, week 42, week 54, week 66, week 78, week 90, week 102 and until progression). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07328425, which also lists 41 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2026.
