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


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

Metastatic disease
Age 18 years
At least two lesions: one lesion that can be treated by radiotherapy and one site of disease that must be uni-dimensionally 10 mm considered as measurable according to RECIST v1.1.

Note that the largest size of the metastases to be irradiated will be 3cm
