Multicohort Trial of Different Schemes of PM14 in Monotherapy and in Combination with Radiotherapy in Soft Tissue Sarcomas and Other Solid Tumor

Launched by GRUPO ESPANOL DE INVESTIGACION EN SARCOMAS · Nov 25, 2021

ClinConnect Summary

This clinical trial is studying a new treatment called PM14 for patients with advanced soft tissue sarcomas and other solid tumors. The goal is to test different ways of giving PM14, either on its own or alongside radiation therapy, to see if it can help improve outcomes for patients while keeping side effects manageable. The trial is set up in different groups, each focusing on specific types of tumors, and involves several hospitals across Spain.

To be eligible for the trial, participants generally need to be between 18 and 75 years old and have a confirmed diagnosis of advanced soft tissue sarcoma or other specified tumors that haven't responded well to previous treatments. Participants will receive PM14 through an intravenous (IV) infusion, which means it will be delivered directly into their bloodstream, and they will be monitored closely for how well the treatment works and any side effects. It's important to know that those interested in joining must also be willing to provide consent for any required tests and samples related to the study.

Eligibility criteria

• Inclusion Criteria:
• • Cohorts A, B, E, and F
• • 1. The patient must voluntarily sign the informed consent before any study test is conducted that is not part of routine patient care.
• • 2. Age: 18-75 years.
• • 3. Patients must have a diagnosis of soft tissue sarcoma with metastasis, and not suitable for metastasectomy or surgery resection or not oncologically recommended metastasectomy. A centralized diagnosis confirmation will be performed and the tumor sample must be available and sent prior to inclusion to this end.
• • 4. A centralized diagnosis of DD liposarcoma or mixoid/hypercellular liposarcoma or leiomyosarcoma must be confirmed for patients in cohort E.
• • 5. A centralized diagnosis of other sarcomas includes: undifferentiated pleomorphic sarcoma (UPS), myxofibrosarcoma, synovial sarcoma, malignant peripheral nerve sheath tumors, sarcoma NOS, fibrosarcoma, pleomorphic rhabdomyosarcoma, pleomorphic liposarcoma, epithelioid sarcoma, clear cell sarcoma, dedifferentiated or aggressive features in solitary fibrous tumor, extraskeletal myxoid chondrosarcoma, angiosarcoma, epithelioid hemangioendothelioma,
• • 6. Patients must have received a previous chemotherapy line in advanced disease unless contraindicated or not indicated.
• • 7. Radiological disease progression must be documented within 6 months prior to study entry.
• • 8. The patient must have been considered eligible for systemic chemotherapy. A maximum of two previous lines for advanced/metastatic disease are allowed.
• • 9. Measurable disease according to RECIST v1.1 criteria.
• • 10. Performance status ≤1 (ECOG).
• • 11. Adequate bone marrow function (hemoglobin \>10 g/dL, neutrophils ≥ 1,500/mm3, platelets ≥ 100,000/mm3). Patients with creatinine clearance ≥ 30 mL/min (Cockcroft and Gault's formula), transaminases ≤ 3.0 times the ULN, total bilirubin ≤ ULN, are acceptable.
• • 12. Men or women of childbearing potential must be using an effective method of contraception before entry into the study and throughout the same and for 3 months (men) and 6 months (women) after ending study treatment. Women of childbearing potential must have a negative serum or urine pregnancy test before study entry.
• • 13. Normal cardiac function with a LVEF ≥ 50% by echocardiogram or MUGA.
• • 14. HBV and HCV serologies must be performed prior to inclusion. If HbsAg is positive it is recommended to reject the existence of replicative phase (HbaAg+, DNA VHB+). If these were positives the inclusion is not recommended, remaining at investigators' discretion the preventive treatment with lamivudine. If a potential patient is positive for anti-HCV antibodies, presence of the virus should be ruled out with a qualitative PCR, or the patient should NOT be included in the study (if a qualitative PCR cannot be performed then patient will not be able to enter the study).
• • 15. Patient must have a central venous catheter for PM14 treatment.
• • Cohort C
• • 1. The patient must voluntarily sign the informed consent before any study test is conducted that is not part of routine patient care.
• • 2. Age: 18-75 years.
• • 3. Patients must have a diagnosis of advanced soft tissue sarcoma, or recurrent head \& neck suitable for reirradiation or other advanced or metastatic solid tumor not suitable for metastasectomy or surgery resection or not oncologically recommended metastasectomy. A centralized diagnosis will be performed and the tumor sample must be available and sent prior to inclusion to this end. For phase II part, onlysoft tissue sarcomas will be enrolled.
• • 4. Patients must have received a previous chemotherapy line in advanced disease.
• • 5. Disease distribution must allow meeting with normal tissue constrains of radiation therapy. Radiation oncologist must confirm this point at local sites.
• • 6. Metastatic spread could be present in several organs (i.e. lungs and pelvic fossa) however, not all the locations have to be irradiated.
• • 7. Those lesions considered for radiation therapy have to be related to symptoms (for phase II).
• • 8. It is allowed that not all the lesions will be under radiation fields. As a general rule, the priority is to select, as target-irradiating lesions, those with greater increase in size and those largest lesions if related with symptoms. Irradiating pulmonary lesions with infiltration of pleural serosa is discouraged.
• • 9. Radiological disease progression must be documented within 6 months prior to study entry.
