Trabectedin in Combination With Olaparib in Advanced Unresectable or Metastatic Sarcoma

August 12, 2025 updated by: University of Michigan Rogel Cancer Center

Phase II Multi-Center Trial of Trabectedin in Combination With Olaparib in Advanced Unresectable or Metastatic Sarcoma

This phase II trial studies how well trabectedin and olaparib work in treating patients with sarcoma that cannot be removed by surgery or has spread to other places in the body. Drugs used in chemotherapy, such as trabectedin, work in different ways to stop the growth of tumor cells, either by killing cells, stopping them from dividing or stopping them from spreading. Olaparib may stop the growth of tumor cells by blocking pathways responsible for repairing damaged cells. Giving trabectedin and olaparib may shrink or stop the tumor from growing.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Olaparib + Trabectedin

There are 2 cohorts. Both cohorts receive the same treatment:

  • Cohort 1: Leiomyosarcoma and liposarcoma
  • Cohort 2: Other bone or soft tissue sarcoma histologies

Treatment consists of 21-day cycles for a maximum of 18 months.
Drug: Olaparib
Olaparib taken by mouth twice daily
Drug: Trabectedin
Trabectedin administered intravenously (IV) every 21 days

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall Response Rate
Time Frame: Up to 2 years
Percentage of participants with complete or partial response as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, within each cohort.
Up to 2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Progression Free Survival
Time Frame: At 6 months
Defined as the duration of time from start of treatment to time of progression. Calculated by the Kaplan-Meier method with errors according to Peto, within each cohort. Median and 6-month PFS will be estimated along with their 95% confidence intervals.
At 6 months
Progression Free Survival
Time Frame: At 1 year after enrollment
Defined as the duration of time from start of treatment to time of progression. Calculated by the Kaplan-Meier method with errors according to Peto, within each cohort. reported as survival probability estimates
At 1 year after enrollment
Overall Survival
Time Frame: At 2 years after enrollment
Calculated by the Kaplan-Meier method with errors according to Peto, within each cohort. Median, 1- and 2-year OS probability estimates will be estimated along with their 95% confidence intervals.
At 2 years after enrollment
Incidence of Adverse Events
Time Frame: Up to 30 days after end of treatment, and average of 4.5 months
The frequency and rates of adverse events occurring in at least 5% of participants and rates of grade 3-5 adverse events will be tabulated by system organ class and preferred term using Common Terminology Criteria of Adverse Events (CTCAE), within each cohort.
