Intervention type: BIOLOGICAL
Group type: EXPERIMENTAL
Intervention: ChAdOx1-MAGEA3-NYESO
Description: Patients commence their Standard of Care (SoC) chemotherapy in combination with an immune checkpoint inhibitor in 3 weekly cycles. Patients are screened during the first 2 cycles of SoC treatment to confirm eligibility for the trial.~Patients who receive trial vaccines (safety run in stage, Arm A of the NSCLC randomisation cohort and Squamous Oesophageal Cancer Cohort) continue to receive their SoC treatment plus:~* First prime ChAdOx1-MAGEA3-NYESO vaccine on Cycle 3 Day 1 of SoC treatment.~* First boost MVA-MAGEA3 vaccine, and if applicable a first boost MVA-NYESO vaccine, 21 days later.~* For patients who have not progressed: second prime ChAdOx1-MAGAEA3-NYESO vaccine 15 weeks following first prime vaccine~* Second boost MVA-MAGAE3 vaccine, and if applicable a second boost MVA-NYESO vaccine, 21 days following second prime vaccine~Patients in Arm B of the NSCLC randomisation cohort will continue to receive their SoC treatment only throughout the trial (i.e. no trial vaccines)
