Detailed Description

This is an open label, dose-seeking phase 1/2 study using escalating doses of LURBINECTEDIN administered intravenously with fixed doses of IPILIMUMAB and NIVOLUMAB administered intravenously. I. Dose Escalation Phase 1 of Study: The study will employ the standard "cohort of three" design (Storer, 1989). Three participants are treated at each of the 2 ascending dose levels. An additional 3 participants will be enrolled if a DLT is observed in one of the three initially-enrolled participants at each dose level. If no DLT occurs after the third participant in a dose level is on study for 6 weeks, enrollment will be opened for escalation to the next highest planned dose level. The DLT window is a total of 6 weeks. The MTD is defined as the highest safely tolerated dose of lurbinectedin, where not more than one participant experienced a DLT, with the next higher dose level having at least two participants who experienced DLT. Participants in the dose escalation study may continue treatment at their designated dose levels until disease progression or unacceptable toxicity occurs or up to a maximum of one year of therapy (up to a maximum of 18 doses of LURBINECTEDIN, 26 doses of NIVOLUMAB, and 5 doses of IPILIMUMAB). No intra-participant dose escalation will take place. Dose of IPILIMUMAB: 1 mg/kg IV over 30 min. q 12 weeks, beginning 2 weeks after the first dose of LURBINECTEDIN, until disease progression or unacceptable toxicity, up to a maximum of 5 doses Dose of NIVOLUMAB: 3 mg/kg over 30 min. q 2 weeks, beginning 2 weeks after first dose of LURBINECTEDIN, until disease progression or unacceptable toxicity, up to a maximum of 26 doses Dose of LURBINECTEDIN: Escalating doses of LURBINECTEDIN IV over 60 minutes q 3 weeks up to a maximum of 18 doses: LURBINECTEDIN # Pts. Dose Level Dose,mg/m2 Max.Volume/24 hrs Every 3 weeks 3-6 I 2.6 1000 ml Every 3 weeks 3-6 II 3.2 1000 ml No dose-escalation will be performed until all the subjects have completed the DLT period of 6 weeks and evaluation of all clinical and laboratory data has been conducted. The phase 2 part of the study will not proceed until either the maximum tolerated dose (MTD) or maximum administered dose (MAD) has been determined. Participants who do not complete the DLT period for reasons other than study drug-related toxicity will be replaced in the same dose cohort. At the discretion of the principal investigator/sponsor, dose escalation may be stopped before an MTD is reached. In this case, the MAD may be chosen based on the standard dose of LURBINECTEDIN of 3.2 mg/m2.

Interventions

Arms, Groups and Cohorts

  • Experimental: Phase 1/2 study using lurbinectedin, ipilimumab and nivolumab for advanced soft tissue sarcoma
    • This is an open label, dose-seeking phase 1/2 study using escalating doses of LURBINECTEDIN administered intravenously with fixed doses of IPILIMUMAB and NIVOLUMAB administered intravenously. I. Dose Escalation Phase 1 of Study: The study will employ the standard “cohort of three” design (Storer, 1989). II.Phase 2 of Study: Following completion of dose escalation, an additional 28-34 previously untreated participants will receive LURBINECTEDIN at the MTD and fixed doses of IPILIMUMAB and NIVOLUMAB to assess overall safety and potential efficacy in a larger number of participants.

Clinical Trial Outcome Measures

Primary Measures

  • Maximum tolerated dose
    • Time Frame: 6 months
    • The maximum tolerated dose (MTD) is defined as the highest safely tolerated dose of lurbinectedin, where not more than one participant experienced a dose limiting toxicity (DLT), with the next higher dose level having at least two participants who experienced DLT.

Secondary Measures

  • Objective response rate
    • Time Frame: 24 months
    • The number of patients achieving a complete response and partial response divided by the number of patients who completed at least one treatment cycle and had a follow up computerized tomography (CT) scan
  • Progression free survival at 6 months
    • Time Frame: 12 months
    • The length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse.
  • Overall survival
    • Time Frame: 36 months
    • The length of time from either the date of diagnosis or the start of treatment for a disease, such as cancer, that patients diagnosed with the disease are still alive. I
  • Correlation of response with circulating tumor DNA
    • Time Frame: 36 months
    • Correlation of response with circulating tumor DNA
