Abstract 1758
Background
REACH (NCT01140347) and REACH-2 (NCT02435433) were two global, randomized, double-blind, placebo (PL)-controlled multicenter, phase 3 studies of RAM vs PL in patients with HCC after prior sorafenib. REACH-2 confirmed overall survival (OS) benefit of RAM for patients with baseline AFP ≥400 ng/mL, consistent with results in a prespecified subgroup of patients in REACH with AFP ≥400 ng/mL.
Methods
Post-hoc pooled analyses were performed to examine efficacy and safety in three age subgroups (<65, ≥65-<75, ≥75 years). In pooled population of patients from REACH (AFP ≥400 ng/mL) and REACH-2, Kaplan-Meier method and Cox proportional hazards regression were performed for OS, progression-free survival (PFS), and deterioration of FHSI-8 total score by three points or more. The incidence of adverse events (AEs) is also reported by age subgroups.
Results
Both intention-to-treat populations were pooled (542 patients in total). Within each age subgroup, baseline characteristics between treatment arms were similar. Patients of < 65 years showed a higher incidence of hepatitis B, extrahepatic spread, and a higher AFP level when compared with patients in older age subgroups across treatment arms. Efficacy outcomes are summarized in the table. Safety profiles of RAM were comparable between <65 and ≥65-<75 age subgroups. The incidence of ≥Grade 3 treatment-emergent AEs was higher in RAM arm than PL arm in ≥ 75 age subgroup (e.g. hypertension and fatigue). A trend toward a delay in the deterioration of symptoms in FHSI-8 for RAM arm was observed in all age subgroups.Table:

Age (years) | Treatment | Number of patients (ITT population) | Median OS (months) | OS hazard ratio (95% CI) | Median PFS (months) | PFS hazard ratio (95% CI) | Number of patients (Safety population) | Median relative dose intensity % | |
---|---|---|---|---|---|---|---|---|---|
REACH (AFP ≥400ng/mL) + REACH-2 | <65 | RAM + BSC | 171 | 8.18 | 0.716 (0.556, 0.922) | 2.73 | 0.616 (0.483, 0.786) | 171 | 98.56 |
PL + BSC | 131 | 4.76 | 1.45 | 128 | 99.80 | ||||
≥65-<75 | RAM + BSC | 93 | 7.62 | 0.593 (0.413, 0.851) | 2.78 | 0.552 (0.390, 0.782) | 93 | 98.03 | |

≥75 | RAM + BSC | 52 | 8.87 | 0.641 (0.390, 1.054) | 4.17 | 0.477 (0.291, 0.781) | 52 | 97.75 | |
PL + BSC | 28 | 6.31 | 1.64 | 28 | 98.57 |
Conclusions
Efficacy and safety profiles of RAM observed in each age subgroup were consistent with those in the entire population. This exploratory subgroup analysis supports the use of RAM for the treatment of HCC with elevated AFP, irrespective of age.
