MEDISARC-SBRT: Study Evaluating the Safety and Efficacy of MEDI5752 in Combination With Stereotactic Radiotherapy in Patients With Metastatic Sarcoma
Study Details
Study Description
Brief Summary
This is a phase I, multicenter, open-label study starting with a dose exploration phase and followed by an expansion phase to evaluate the safety profile and the preliminary activity of the bispecific antibody anti PD-1/CTLA-4 MEDI5752 in combination with SBRT delivered on one lung metastatic lesion, in patients with metastatic soft tissue sarcoma.
Dose exploration phase:
The primary objective of this dose exploration phase I trial is to determine the Maximum Tolerated Dose and the toxicity profile of MEDI5752 when administrated with stereotactic radiotherapy in patients with metastatic sarcoma with lung metastases.
Expansion phase:
The primary objective of the expansion phase is to investigate preliminary activity of MEDI5752 when administrated with stereotactic radiotherapy in patients with metastatic sarcoma with lung metastases.
A maximum of 20 evaluable patients will be included in this trial.

| Experimental: Patients with metastatic soft tissue sarcoma with lung metastases

Combination Product: SBRT + MEDI5752
SBRT (5 fractions of 10 Gy every two or three days) will be delivered to one lung metastasis (12 days maximum) in combination with MEDI5752* administered intravenously.
The first dose of MEDI5752 will be administered on the day of the last SBRT fraction, then every 3 weeks for up to a maximum of 12 months.
* Dosing 500 mg or 750 mg, according to the recommended dose determined during the dose exploration phase

Outcome Measures
Primary Outcome Measures
- Dose exploration Phase: The incidence of the Dose-limiting toxicity (DLT) [6 weeks after the last dose of radiotherapy for each patient]
For each patient, DLT incidence will be evaluated during the first cycle.
- Expansion phase: the rate of patients alive and without progression at 3 months. [3 months post treatment for each patient]
Secondary Outcome Measures
- Dose exploration and Expansion Phases: Safety will be evaluated using the NCI-CTCAE Version 5.0. [15 months for each patient]
- Dose exploration and Expansion Phases: Objective Response Rate (ORR) defined as the rate of patients with an objective response (i.e. CR or PR according to RECIST v1.1 criteria). [15 months for each patient]
- Dose exploration and Expansion Phases: Progression-Free Survival (PFS) defined (per RECIST v1.1 criteria) as the time from treatment initiation until progression or death from any cause, whichever occurs first. [15 months for each patient]
- Dose exploration and Expansion Phases: Time to progression of irradiated lesions defined as the time from treatment initiation until progression of irradiated lesions or death from any cause. [15 months for each patient]
- Dose exploration and Expansion Phases: Time to progression outside the irradiation field defined as the time from treatment initiation until progression outside the irradiation field or death from any cause. [15 months for each patient]
- Dose exploration and Expansion Phases: Overall Survival (OS) defined as the time from treatment initiation to death from any cause. [15 months for each patient]
