| Experimental: 89Zr-atezolizumab PET scan All patients will undergo two 89Zr-atezolizumab PET scans, one at baseline and one after two doses carboplatin induction treatment. The 89Zr-atezolizumab PET scan will be performed 4 days after tracer injection. Procedures within the ImaGelato study will be completed after the two 89Zr-atezolizumab PET scans, but patients will continue treatment with carboplatin combined with atezolizumab in the GELATO trial. | Other: 89Zr-atezolizumab PET scan Patients receive a total amount of 10 mg unlabeled atezolizumab, this will be added to the tracer to prevent rapid clearance during imaging. A labeled dose of 37 Megabequerell (MBq) 89Zr-atezolizumab (±10%; 1 Millicurie) will then be administered. The tracer will be administered intravenously (i.v.). All patients will undergo two 89Zr-atezolizumab PET scans, one at baseline and one after two doses carboplatin induction treatment. After each tracer injection, 89Zr-atezolizumab PET scans will be performed on day 4 (96 ± 6h after tracer administration). |
