A Case of Advanced Hepatocellular Carcinoma with Partial Response after Continuous Ramucirumab Treatment beyond Radiological Progression.

ABSTRACT: A 73-year-old male was initially treated with sorafenib for advanced stage HCC. However, the disease progressed 2 months after starting sorafenib. Progressive disease (PD) was confirmed by radiological examination, which revealed mediastinal and abdominal lymph node metastasis, pulmonary metastasis, and intrahepatic recurrence. The patient was enrolled in the REACH-2 (NCT02435433) trial and randomized to receive ramucirumab (8 mg/kg div. every 2 weeks). The patient had a Child-Pugh score of 6A and his AFP level was found to be 1,256.8 ng/mL at initiation. Radiological examination revealed PD, 5 months after starting ramucirumab. Ramucirumab treatment was continued after the confirmation of radiological PD, not but clinical progression, as allowed by the study protocol. His AFP level increased after continuous ramucirumab treatment, however, it suddenly decreased from 7,653 ng/mL to within normal limits 10 months after initiation of ramucirumab treatment. Radiological evaluation revealed a significant decrease in the size of the tumors, which constituted a partial response (PR). We reported a rare case of advanced HCC with PR to a continuous ramucirumab treatment after radiological PD.

Project description:BackgroundPreclinical data suggest that vascular endothelial growth factor (VEGF) and transforming growth factor (TGF)-β signaling interact to stimulate angiogenesis and suppress antitumor immune responses. Thus, combined inhibition of both pathways may offer greater antitumor activity compared with VEGF-targeted antiangiogenic monotherapy against hepatocellular carcinoma (HCC).MethodsThis is a multicenter, open-label, phase 1b study of galunisertib, an inhibitor of TGF-β receptor 1, and ramucirumab, an anti-VEGF receptor 2 antibody, in patients with advanced HCC aiming to define the maximum tolerated dose (MTD). Secondary objectives included safety, pharmacokinetics (PK), antitumor efficacy, and plasma alpha-fetoprotein and TGF-β kinetics. Dose escalation employed a 3 + 3 design. Patients received galunisertib at 80 mg (cohort 1) or 150 mg (cohort 2) orally twice a day on days 1-14 of a 28-day cycle combined with ramucirumab 8 mg/kg intravenously every 2 weeks.ResultsEight patients were enrolled: three in cohort 1 and five in cohort 2 (two patients were unevaluable due to rapid disease progression and replaced). No dose-limiting toxicities were observed. Treatment-related adverse events (AEs) of any grade in ≥2 patients included nausea (25%) and vomiting (25%). There was one Grade 3 treatment-related AE, a cerebrovascular accident possibly related to ramucirumab. Galunisertib exposure was dose-proportional and not affected by ramucirumab. The RECIST version 1.1 objective response rate and disease control rate were 0% and 12.5%, respectively.ConclusionCombination therapy was safe and tolerable and displayed favorable PK. The MTD was established at galunisertib at 150 mg orally twice a day and ramucirumab 8 mg/kg intravenously every 2 weeks. The results do not support the preclinical hypothesis that blocking TGFβ signaling enhances efficacy of VEGF-targeted therapy; thus further clinical development was halted for the combination of galunisertib and ramucirumab.

Project description: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.
