Exposure–response relationship of ramucirumab in East Asian patients from RAINBOW: a randomized clinical trial in second-line treatment of gastric cancer

Background Ramucirumab is a recombinant human IgG1 neutralizing monoclonal antibody specific for vascular endothelial growth factor receptor-2. Second-line ramucirumab, in conjunction with paclitaxel (ramucirumab 8 mg/kg or placebo in combination with 80 mg/m 2 paclitaxel), has been shown to be effe...

description Background Ramucirumab is a recombinant human IgG1 neutralizing monoclonal antibody specific for vascular endothelial growth factor receptor-2. Second-line ramucirumab, in conjunction with paclitaxel (ramucirumab 8 mg/kg or placebo in combination with 80 mg/m 2 paclitaxel), has been shown to be effective and safe in patients with advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma in RAINBOW, a global phase III randomized clinical trial. We conducted an exploratory exposure–response analysis of efficacy and safety of ramucirumab in East Asian patients from the RAINBOW trial. Methods Using sparse pharmacokinetic samples collected in the RAINBOW trial, a population pharmacokinetic analysis was conducted to predict ramucirumab minimum trough concentration at steady state ( C min,ss ) using a nonlinear mixed-effect modeling approach. Kaplan–Meier and Cox proportional hazards analyses were conducted to evaluate ramucirumab exposure ( C min,ss ) and efficacy relationship by overall survival and progression-free survival. Exposure-safety relationships were assessed descriptively. Results Two hundred and twenty-two East Asian patients were included in this exposure–response analysis. Higher ramucirumab C min,ss was associated with longer overall survival ( p  = 0.0115) and progression-free survival ( p  = 0.0179) in this patient cohort. Patients with higher ramucirumab C min,ss (≥56.87 ng/ml median) had higher incidences of grade ≥3 leukopenia and neutropenia, but not febrile neutropenia or hypertension. Conclusions This exploratory analysis suggests a positive relationship between efficacy and ramucirumab exposure with manageable toxicities in East Asian patients from RAINBOW, consistent with the overall exposure–response analysis from this trial. A regimen with a higher dosage of ramucirumab warrants further consideration for East Asian patients with gastric/GEJ cancer.
