Background: Immune checkpoint inhibitors (ICIs) and tyrosine kinase inhibitors (TKIs) are widely adopted in contemporary advanced HCC (aHCC) treatment algorithms. Nevertheless, the optimal strategy for treatment after ICI exposure is unknown. We evaluated the pattern of use, response, survival and safety of TKIs in aHCC patients who previously received ICIs. Methods: We performed an international, multi-centre study of aHCC patients who received TKIs after prior treatment with ICIs. Objective response rate (ORR), disease control rate (DCR), time-to-progression (TTP), overall survival (OS) and adverse events (AE) were assessed. Results: Between January 2015 and December 2020, one-hundred and forty-eight patients were included. The median age was 63 (range 29-84) and 78.4% were of Child-Pugh Grade A. 75.7% had hepatitis-B related HCC. 64.9% received TKI as single agent and 35.1% received TKI in combination with other agents. 75% who received TKI combinations had concomitant ICIs. 48.6% had prior TKIs. The median follow-up was 23.3 months. For single agent TKI patients, the ORR was 14.6%, DCR was 38.5%, median TTP was 3.9 months (95% C.I. 3.3-4.5) and median OS was 8.6 months (95% C.I. 5.8-11.4). For patients receiving TKI combinations, the ORR was 25%, DCR was 38.5%, median TTP was 3.5 months (95% C.I. 1.7-5.2) and median OS was 15.1 months (95% C.I. 5.7-24.5). There were no significant differences in ORR, DCR and median OS between patients who had primary resistance to prior ICI compared to those with acquired ICI resistance and between those who were TKI-naive compared to those who were TKI-exposed. Notably, patients who received TKI-ICI combinations had significantly superior survival compared to single agent TKI patients (median OS 15.1 months (95% C.I. 6.7-23.5) vs. 8.6 months (95% C.I. 5.6-11.7), p = 0.011) but not significantly superior ORR, DCR or TTP. Amongst patients who received single agent TKI and were naive to both sorafenib and lenvatinib, those who received lenvatinib had significantly superior DCR, TTP and OS compared to those who received sorafenib (DCR 51.5% vs 25.8%, p = 0.035; median TTP 6.3 months (95% C.I. 3.0-9.7) vs. 1.8 months (95% C.I. 0-3.6), p = 0.003; median OS 12.0 months (95% C.I. 7.0-17.0) vs. 5.9 months (95% C.I. 1.9-10.0), p = 0.008). 70.3% and 15.5% of all patients, and 77.1% and 15.6% of patients who received single agent TKI experienced all grade and grade ≥3 AEs respectively. The most common AEs were hand foot syndrome, skin rash and diarrhea. Conclusions: TKIs can achieve encouraging anti-tumour response and survival outcomes with acceptable safety in prior ICI-treated aHCC patients. Moreover, TKI-ICI combinations were associated with better survival than single agent TKIs. Notably, among patients who received single agent TKIs, lenvatinib had significantly better responses and survival results than sorafenib.
