Summary

This trial is studying the effectiveness of combining lurbinectedin with radiotherapy in patients with locally advanced, resectable, high-grade sarcomas. It is being conducted at multiple centers and will

Who is the study for?
This trial is for individuals with locally advanced, high-grade soft tissue sarcomas that can be surgically removed. Participants must meet certain health standards to ensure they can safely receive the treatments.
What is being tested?
The study is testing how well lurbinectedin works alongside radiotherapy before surgery in patients with soft tissue sarcoma. It's an open-label trial, meaning everyone knows which treatment they're getting.
What are the potential side effects?
Potential side effects may include reactions related to lurbinectedin such as fatigue, nausea, hair loss, and lowered blood cell counts leading to increased infection risk.

Trial Design

6Treatment groups
Experimental Treatment
Group I: Phase 2, Cohort 3: Retroperitoneal sarcomaExperimental Treatment3 Interventions
Participants will receive the maximum tolerated dose of neoadjuvant lurbinectedin IV once every cycle (a cycle is 21 days) in combination with 6 weeks of pre-operative conventional external beam radiation therapy given as 45-50.4 Gy delivered over 25-28 fractions starting on cycle 1 for participants with retroperitoneal sarcoma. Non-investigational surgery will take place 4-6 weeks after completion of radiation therapy. Participants with metastatic disease at the time of study enrollment may be able to continue study treatment for 2 years from the time of initiating treatment. Participants with localized disease at the time of study enrollment may continue study treatment for approximately 3 months AND then be followed on-study surveillance.
Group II: Phase 2, Cohort 2: Extremity myxoid liposarcomaExperimental Treatment3 Interventions
Participants will receive the maximum tolerated dose of neoadjuvant lurbinectedin IV once every cycle (a cycle is 21 days) in combination with 2 weeks of pre-operative radiation given as 35 Gy in 5 fractions (gross tumor volume (GTV)) with fractions administered at least every other day starting on cycle 2 for participants with extremity myxoid Liposarcoma. Non-investigational surgery will take place 4-6 weeks after completion of radiation therapy. Participants with metastatic disease at the time of study enrollment may be able to continue study treatment for 2 years from the time of initiating treatment. Participants with localized disease at the time of study enrollment may continue study treatment for approximately 3 months AND then be followed on-study surveillance.
Group III: Phase 2, Cohort 1: Extremity and trunk sarcomaExperimental Treatment3 Interventions
Participants will receive the maximum tolerated dose of neoadjuvant lurbinectedin IV once every cycle (a cycle is 21 days) in combination with 2 weeks of pre-operative radiation given as 35 Gy in 5 fractions (gross tumor volume (GTV)) with fractions administered at least every other day starting on cycle 2 for participants with extremity and trunk sarcoma. Non-investigational surgery will take place 4-6 weeks after completion of radiation therapy. Participants with metastatic disease at the time of study enrollment may be able to continue study treatment for 2 years from the time of initiating treatment. Participants with localized disease at the time of study enrollment may continue study treatment for approximately 3 months AND then be followed on-study surveillance.
Group IV: Phase 1b, Cohort 3: Retroperitoneal SarcomaExperimental Treatment3 Interventions
Participants will receive up to 3.2 mg/m\^2 of neoadjuvant lurbinectedin IV once every cycle (a cycle is 21 days) in combination with 6 weeks of pre-operative conventional external beam radiation therapy given as 45-50.4 Gy delivered over 25-28 fractions starting on cycle 1 for participants with retroperitoneal sarcoma. Non-investigational surgery will take place 4-6 weeks after completion of radiation therapy. Participants with metastatic disease at the time of study enrollment may be able to continue study treatment for 2 years from the time of initiating treatment. Participants with localized disease at the time of study enrollment may continue study treatment for approximately 3 months AND then be followed on-study surveillance.
Group V: Phase 1b, Cohort 2 (Extremity Myxoid Liposarcoma)Experimental Treatment3 Interventions
