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).
