The GIDEON (Global Investigation of therapeutic DEcisions in hepatocellular carcinoma and Of its treatment with sorafeNib) study is a large prospective registry of patients with liver cancer who were treated with sorafenib. The aims were to evaluate the safety and tolerability of sorafenib among those in which the liver was not functioning properly. The study showed that the safety profile of sorafenib was consistent across patients with preserved liver function and those in which the liver was not functioning properly, and therefore, suggesting that sorafenib may be a valid treatment for some patients with liver impairment.
BackgroundGIDEON (Global Investigation of therapeutic DEcisions in hepatocellular carcinoma [HCC] and Of its treatment with sorafeNib) is a global, prospective, non-interventional study undertaken to evaluate the safety of sorafenib in patients with unresectable HCC in real-life practice, including Child-Pugh B patients who were excluded from clinical trials.MethodsPatients with unresectable HCC, for whom the decision to treat with sorafenib, based on the approved label and prescribing guidelines, had been taken by their physician, were eligible for inclusion. Demographic data and disease/medical history were recorded at entry. Sorafenib dosing and adverse events (AEs) were collected at follow-up visits. The second interim analysis was undertaken when ∼1500 treated patients were followed up for ≥ 4 months.ResultsOf the 1571 patients evaluable for safety, 61% had Child-Pugh A status and 23% Child-Pugh B. The majority of patients (74%) received the approved 800 mg initial sorafenib dose, regardless of Child-Pugh status; however, median duration of therapy was shorter in Child-Pugh B patients. The majority of drug-related AEs were grade 1 or 2, and the most commonly reported were consistent with previous reports. The incidence and nature of drug-related AEs were broadly similar across Child-Pugh, Barcelona Clinic Liver Cancer (BCLC) and initial dosing subgroups, and consistent with the overall population.ConclusionsConsistent with the first interim analysis, overall safety profile and dosing strategy are similar across Child-Pugh subgroups. Safety findings also appear comparable irrespective of initial sorafenib dose or BCLC stage. Final analyses in > 3000 patients are ongoing.
Global variation exists in TACE use in sorafenib-treated HCC patients. The combination of TACE with sorafenib appears to be a well-tolerated and viable therapeutic approach.
The GIDEON study is generating a large, robust database from a broad population of patients with uHCC. First interim analyses have shown global and regional differences in patient characteristics, disease aetiology and practice patterns. Subsequent planned analyses will allow further evaluation of early trends.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
