Summary

Basket trial concept to independently and simultaneously assess the effects of the association of atezolizumab + BDB001 + radiotherapy in multiple solid tumors.

Detailed description

6 independent, multicenter, prospective, single-arm phase II trials, based on 2-stage Simon's optimal design, will be conducted in parallel to assess the efficacy of atezolimab + BDB001+ radiotherapy, separately, in distinct populations of solid tumors: * Population 1: pancreatic cancer * Population 2: virus-associated tumors * Population 3: anti-PD-1/L1 refractory non-small lung cancer * Population 4: soft-tissue sarcoma * Population 5: anti-PD-1/L1 refractory bladder cancer * Population 6: triple negative breast cancer

Conditions

• Solid Tumor, Adult
• Pancreatic Cancer
• Virus-associated Tumors
• Non Small Cell Lung Cancer
• Melanoma
• Bladder Cancer
• Triple Negative Breast Cancer

Interventions

Type	Name	Description
DRUG	Association atezolizumab + BDB001 + RT	A treatment cycle consits of 3 weeks. Atezolizumab will be administered as a 1-hour infusion on day 1 every 3 weeks (1200 mg). BDB001 will be administered by a 30-minute intravenous infusion before atezolizumab, on Days 1, 8, and 15 of cycles 1, 2, and 3. Then from cycle 4 BDB001 will be administered on Day 1 every 3 weeks. Radiotherapy will start at least one week after the first administration of atezolizumab and at the latest before the 2nd administration. All participants will be treated by high dose irradiation in stereotactic conditions on non-injected metastasis: 3 to 5 fractions for a total dose between 27 Gy and 60 Gy.
