Introduction: In a multicenter, open-label, parallel-group, randomized, phase 2 study for pretreated advanced hepatocellular carcinoma (HCC), camrelizumab showed potent antitumor activity and acceptable safety profile. The aim of this report was to provide long-term data and evaluate potential benefit of treatment with camrelizumab beyond progression. Methods: From November 15, 2016, to November 16, 2017, 217 patients received camrelizumab 3 mg/kg intravenously every 2 or 3 weeks. Treatment beyond first Response Evaluation Criteria in Solid Tumors (RECIST)-defined progression (TBP) with camrelizumab was allowed. Results: At data cutoff of December 16, 2019 (>2 years after the last patient enrollment; median duration of follow-up, 13.2 months [IQR 5.7-25.8]), 14 (43.8%) of the 32 responses per blinded independent central review were ongoing. The median duration of response was not reached (range 2.5-30.5 + months). The ongoing response rates at 12, 18, and 24 months were 68.3% (95% confidence interval [CI] 47.7-82.2), 59.8% (95% CI 38.8-75.6), and 53.1% (95% CI 31.0-71.0), respectively. The median overall survival (OS) was 14.2 months (95% CI 11.5-16.3). The 18- and 24-month OS rates were 41.3% (95% CI 34.6-47.9) and 33.7% (95% CI 27.3-40.2), respectively. Of the 172 patients who experienced RECIST-defined progression per investigator, 102 received TBP, while 70 did not (non-TBP). The median OS was 16.9 months (95% CI 13.3-22.6) in the TBP group versus 9.4 months (95% CI 5.8-14.8) in the non-TBP group, and the 18- and 24-month OS rates were 47.5% (95% CI 37.3-56.9) versus 33.1% (95% CI 22.3-44.3) and 38.8% (95% CI 29.2-48.4) versus 23.2% (95% CI 13.8-34.1), respectively. No new safety signals of camrelizumab were observed. Conclusions: With prolonged follow-up, camrelizumab continues to demonstrate the durable response and long survival in pretreated advanced HCC patients with manageable toxicities, especially in those who continued the treatment beyond first RECIST-defined progression.
