Abstract 4562

Background

LEN is a multikinase inhibitor of VEGFR 1–3, FGFR 1–4, PDGFRα, RET, and KIT. In a phase 3 randomized, open-label, first-line study in pts with uHCC, LEN demonstrated a treatment effect on overall survival (OS) by statistical confirmation of noninferiority to SOR, with an improved objective response rate.(Kudo et al. Lancet 2018) Preliminary biomarker analyses (n = 114) have been presented.(Finn et al. ESMO 2017) We now present the final biomarker analyses and correlations with efficacy for all pts with serum samples (n = 407).

Methods

954 Pts with uHCC were randomized 1:1 to LEN (≥ 60 kg: 12 mg/day; < 60 kg: 8 mg/day) or SOR 400 mg BID. Serum samples were collected (LEN, n = 279; SOR, n = 128) at baseline and during the study; VEGF, ANG2, FGF19, FGF21, and FGF23 were assayed by ELISA. Correlations with tumor response (by independent imaging review per mRECIST: complete or partial responses [CR/PR] vs others) were analyzed using Wilcoxon rank-sum tests. Baseline biomarker levels were analyzed by quartiles: low (0–25%), middle (25–75%), or high (75–100%). Correlations with OS were examined by Cox regression, Kaplan-Meier plots, and log-rank tests. All P-values are nominal.

Results

Both treatments increased VEGF levels, but only LEN increased FGF19 and FGF23 levels. In the LEN arm, pts with CR/PR had a greater increase in FGF19 and FGF23 from baseline vs nonresponders (FGF19: 55.2% vs 18.3%, P = 0.0140; FGF23: 48.4% vs 16.4%; P = 0.0022). Higher VEGF, ANG2, and FGF21 baseline levels were associated with worse OS in both arms. However, for pts with high baseline FGF21 (LEN, n = 70; SOR, n = 27), OS was longer for LEN vs SOR (median, 10.9 vs 6.8 months; HR, 0.528; 95% CI, 0.328–0.849; P = 0.0075), and correlations with OS and treatments were observed between high and low–middle groups (Pinteraction=0.0397).

Conclusions

Differences in biomarker changes between treatments may reflect distinct target engagements for LEN and SOR. Increased baseline VEGF, ANG2, and FGF21 may be prognostic for shorter OS with both treatments, and increased FGF21 may be predictive for reduced OS with SOR. These results are hypothesis-generating and warrant further study.
