Trial Summary

What is the purpose of this trial?

This trial is testing a new drug, lurbinectedin, combined with an existing chemotherapy drug, doxorubicin, in patients with advanced leiomyosarcoma. The goal is to see if this combination is safe and more effective than doxorubicin alone. Both drugs work by damaging the DNA in cancer cells, leading to their death. Lurbinectedin is a synthetic marine-derived anticancer agent that has shown promise in treating certain types of cancer.

• Lurbinectedin (Other)

Trial Overview The trial is testing the combination of lurbinectedin and doxorubicin versus lurbinectedin alone for treating leiomyosarcoma. It has two parts: one for tolerability assessment and another randomized part to compare effectiveness.

Participant Groups

Group I: Lurbinectedin + Doxorubicin at RP2D Experimental Treatment 2 Interventions

The randomized two arm phase 2 trial will begin following the determination of the RP2D for lurbinectedin and doxorubicin. * Participants will be randomized 1:1 to enroll to either Arm 1 or Arm 2 * Participants enrolled to Arm 1 will receive Lurbinectedin with Doxorubicin at the RP2D defined during the phase 1b portion of the trial.

Group II: Lurbinectedin + Doxorubicin Phase I Experimental Treatment 2 Interventions

The phase 1b trial will follow a standard 3+3 design. Upon determination of the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of lurbinectedin plus doxorubicin. A treatment cycle will be defined as 21 consecutive days. Treatment will be administered on an outpatient basis * Lurbinectedin * Doxorubicin

Group III: Doxorubicin Monotherapy Active Control 1 Intervention

The randomized two arm phase 2 trial will begin following the determination of the RP2D for lurbinectedin and doxorubicin. * Participants will be randomized 1:1 to enroll to either Arm 1 or Arm 2 * Participants enrolled to Arm 2 will receive Doxorubicin at the standard dose of 75 mg/m2
