Trabectedin Plus Radiotherapy in Soft Tissue Sarcoma Patients (TRASTS)

Phase I-II Prospective Trial, Multicenter, Open Label, Exploring the Combination of Trabectedin Plus Radiotherapy in Soft Tissue Sarcoma Patients

Phase I-II trial that combines trabectedin plus radiotherapy for tumor reduction response measure in four cohorts of patients:

Cohort A: Patients with diagnosis of non-operable or unresectable or not oncologically recommended metastasectomy of limited to lung metastases soft tissue sarcoma.

Cohort B: Patients with locally advanced resectable Myxoid Liposarcoma. Cohort C: Patients with retroperitoneal and resectable soft tissue sarcoma (liposarcoma and leiomyosarcoma).

Cohort D (Phase II only): Patients with well differentiated liposarcoma and G2 dedifferentiated liposarcoma (with less than 30% dedifferentiated component).

Phase I: escalating dose of 1.3 or 1.5 mg/m2. Phase I for cohort C: de-escalating dose of 1.5 or 1.3mg/m2 Radiotherapy for cohort A: 30Gy in 10 fractions (3Gy/fraction). Radiotherapy for cohort B: 45Gy in 25 fractions (1.8Gy/fraction). Radiotherapy for cohort C: 45Gy in 25 fractions (1.8Gy/fraction).

Radiotherapy for cohort D: 45Gy in 25 fractions (1.8Gy/fraction). A translational substudy is developed to analyse different biomarkers predictive value.

Cohorts A and B are closed to recruitment in 2023.

Study Overview

• Status: Recruiting
• Conditions: Sarcoma, Soft Tissue; Leiomyosarcoma; Liposarcoma; Liposarcoma, Myxoid; Pleomorphic Liposarcoma
• Intervention / Treatment: Drug: Trabectedin; Radiation: Radiotherapy

Detailed Description

In this study investigators plan to measure tumor response (RECIST and Choi criteria) when administering trabectedin standard dose or inferior with simultaneous radiotherapy treatment. The hypothesis states that administering trabectedin at 1.3mg/m2 or ≤1.5mg/m2 plus Radiotherapy 30-45Gy shows synergic activity that turns into tumor shrinkage.

A phase I trial (dose escalation -or de-escalation for cohort C- level of 1.3 or 1.5 mg/m2) will provide the proper dose level to perform a phase II trial to measure RECIST and Choi response, progression free survival, overall survival and register safety and quality of life details.

Four cohorts are indicated for this trial:

Cohort A: Patients with diagnosis of non-operable or unresectable or not oncologically recommended metastasectomy of limited to lung metastases soft tissue sarcoma.

Cohort B: Patients with locally advanced resectable Myxoid Liposarcoma, Cohort C:Patients with retroperitoneal and resectable soft tissue sarcoma (liposarcoma and leiomyosarcoma).

Cohort D: Patients with well differentiated liposarcoma and G2 dedifferentiated liposarcoma (with less than 30% dedifferentiated component) Unlimited cycles of chemotherapy are considered to be beneficial for cohort A patients, whereas cohort B and C only 3 cycles are indicated. About radiotherapy treatment, 30Gy will be given to cohort A patients, whereas cohort B and C will receive 45Gy. TCs and MRI are selected for imaging purposes.

Phase I:

For cohorts A and B:Trabectedin at two dose escalation levels:

0 1.3 mg/m2 as a 24h I.V. infusion

1 1.5 mg/m2 as a 24h I.V. infusion

For cohort C:Trabectedin at two dose de-escalation levels:

0 1.5 mg/m2 as a 24h I.V. infusion

-1 1.3 mg/m2 as a 24h I.V. infusion

Administration of trabectedin with a portable pump, i.v infusion of 24h, in cycles of 3 weeks.

Premedication:

• 4 mg oral dexamethasone 24h and 12h before chemotherapy administration.
• 20 mg I.V. dexamethasone 30minutes before treatment.
• Ondansetron or analogue will also be given prior to trabectedin.

Pathology review, radiology review and radiotherapy review are performed to each patient.

Several biomarkers are selected to perform FFPE tumor assays in relation to prediction

2. Aged equal or over 18.
3. Patients must have a diagnostic of Soft Tissue Sarcoma with metastasis limited to lung, and not suitable for metastasectomy or surgery resection or not oncologically recommended metastasectomy.A centralized diagnostic will be performed, the tumor sample must be available and sent prior to inclusion.

5. Metastatic spread could be present in two organs at maximum (i.e. lungs and pelvic fosa).
6. Those lesions considered for radiation therapy have to be considered as target lesions as well. (i.e. in a patient with nodules in lungs, those lesions selected for radiation therapy have to include at least the target lesions)
7. It is allowed that not all the lesions will be under radiation fields. As a general rule, it will be prioritized to select, as target-irradiating lesions, those with greater increase in size and those largest lesions. It should be discouraged to irradiate pulmonary lesions with infiltration of pleural serosa.
8. Patients must have documentation of disease progression within 6 months prior to study entry.
