Abstract Background Life expectancy longer than 12 weeks(w) is a common inclusion criteria for most Ph1. Despite the presence of several prognostic indeces in drug development, their value for patient selection in clinical trials is not well established. VIO is a immune-oncology score validated in patients treated in Ph1 with immunotherapy (Hierro C. ESMO 2018), which includes 5 variables: albumin upper limit normal, dNLR (derived neutrophil/(leukocytes minus neutrophils) ratio) >3, >2 sites of metastases, and presence of liver metastases. Methods VIO variables were retrospectively collected from 384 patients with advanced disease treated in Ph1 with immune checkpoint inhibitors (ICIs) or targeted agents (TAs) since 2011 to 2017 at Vall d´Hebron Hospital. The following VIO clusters were defined based on Kaplan Meier OS estimates: good prognosis (0‐1), intermediate (2‐3) and poor prognosis (4‐5). We aimed to improve patient selection for Ph1 (independent of treatment type) by developing a composite VIO score that is associated with overall survival (OS), progression free survival (PFS) and objectively estimated life expectancy at 12 w. Results From the 384 patients treated with ICIs (53.6%) or TAs (45.4%) in Ph1, 206 (53.6%) were female, 210 were treated with monotherapy (54.7%). Most frequent tumor types were: colorectal (17.4%), breast (14.1%) and lung (9.4%). The median follow-up was of 8.4 months (m) [IC95% 7.3-9.5]. Estimated median OS in good prognosis (33.3% of all pts), intermediate (54.2%) and poor prognosis (12.5%) was 16.2 m (13.3‐19.1), 7.8 m (6.9‐8.6) and 2.9 m (2.1-3.8), respectively (log rank test, p  Conclusions VIO score is a strong prognostic index independent of the treatment type and it could be useful as a tool to estimate objectively life expectancy Legal entity responsible for the study The authors.
