Figures & data

Table 1. Patient and tumor characteristics at baseline (ITT population)

Figure 1. CONSORT flow diagram of the LICC trial. * One patient in the tecemotide arm did not receive vaccination but received CP and was included in the ITT and safety population. In the tecemotide arm, one patient had one R2 resected metastasis besides R0 resected metastases and one patient had one RX metastasis besides R0 and R1 resected metastases. These patients were allocated to the “Non-R0” subgroup in the ITT population and were excluded from the PP population. A centralized radiologic review was conducted for 80 patients, which led to the exclusion of 11 patients (n = 7 tecemotide arm, n = 4 placebo arm) with residual disease at baseline from the per-protocol (PP) population. Abbreviations: ITT: intention-to-treat population, PP: per-protocol population
