Summary

Assessment of the efficacy and safety of JX-594 and metronomic cyclophosphamide in patients with advanced soft-tissue sarcoma and advanced breast cancer, once the Maximum Tolerated Dose have been determined (phase I trial). Phase I study: this is a prospective open-labeled phase I trial based on a dose escalating study design assessing two dose levels of JX594 when prescribed in combination with metronomic cyclophosphamide. Phase II trials with two treatments strategies: Metronomic CP + JX-594: phase II study sarcoma: this is a monocentric, randomized two-arm non comparative phase 2 study assessing efficacy and safety of JX-594 in association with metronomic cyclophosphamide in patients with advanced soft-tissue sarcoma. Metronomic CP + JX-594: phase II study breast cancer: this is a monocentric, single-arm phase II study, assessing efficacy and safety of JX-594 in association with metronomic cyclophosphamide in patients with advanced breast cancer. Metronomic CP + JX-594 + Avelumab: phase II study sarcoma: this is a monocentric, single arm phase II study assessing efficacy and safety of avelumab in combination with IT JX-594 and metronomic cyclophosphamide in patients with advanced soft-tissue sarcoma. Metronomic CP + JX-594 + Avelumab:: phase II study breast cancer: this is a monocentric, single-arm phase II study, assessing efficacy and safety of avelumab in combination with IT JX-594 and metronomic cyclophosphamide in patients with advanced breast cancer.

Detailed description

For the phase I study, this is a prospective open-label phase I trial based on a dose escalating study design assessing two dose level of JX-594 when associated to metronomic cyclophosphamide. For the phase II study, two distincts treatment strategies will be evaluated. First, treatment by JX-594 and metronomic cyclophosphamide: * stratum soft-tissue sarcoma, this is a monocenter, randomized non comparative phase II clinical trial. This phase II trial was based on an optimal 2-stage Simon's design. Randomization 2:1 with 2 patients randomized in experimental arm n°1 (association of metronomic cyclophosphamide and JX-594) and 1 patient randomized in control arm n°2 (treatment by metronomic cyclophosphamide alone). * stratum breast cancer, this is a monocenter, one-arm phase II clinical trial, based on two-stage optimal Simon's design (association of metronomic cyclophosphamide and JX-594). Second, treatment by Avelumab, intratumoral JX-594 and metronomic cyclophosphamide: * stratum soft-tissue sarcoma, this is a monocenter, single arm phase II clinical trial based on an optimal 2-stage Simon's design. * stratum breast cancer, this is a monocenter, one-arm phase II clinical trial, based on two-stage optimal Simon's design).

Interventions

Type	Name	Description
DRUG	Cyclophosphamide and JX-594 dose escalation	Metronomic cyclophosphamide will be administered orally, 50 mg twice daily, one week on/one week off. JX-594 will be administered, as designated by assigned dose-level, intraveinously, on Days 8 and 22 of cycle 1, and on days 8 of each subsequent cycles. One cycle consits of 28 days.
DRUG	Cyclophosphamide and JX-594	Metronomic cyclophosphamide will be administered orally, 50 mg twice daily, one week on/one week off. JX-594 will be administered, as the dose recommended in the experimental phase I dose escalating study, intraveinously, on Days 8 and 22 of cycle 1, and on days 8 of each subsequent cycles. One cycle consits of 28 days.
DRUG	Cyclophosphamide	Metronomic cyclophosphamide will be administered orally, 50 mg twice daily, one week on/one week off.
DRUG	Avelumab and JX-594 and Cyclophosphamide	Avelumab will be administered by intravenous infusion (10 mg/kg) every 2 weeks, starting at Day 15 of cycle 1. Cyclophosphamide wil be administered bi-daily (50 mg x 2), starting 7 days prior to cycle 1 day 1 ("impregnation phase") and given on a week on/week off schedule. JX-594 will be administered by intratumoral injection (1 x109 p.f.u) on day 1 of cycle 1, every 2 weeks, for a maximum of 4 injections .
