Sintilimab combined with apatinib plus capecitabine in the treatment of unresectable hepatocellular carcinoma: A prospective, open-label, single-arm, phase II clinical study.

ABSTRACT:

Objective

To evaluate the efficacy and safety of sintilimab combined with apatinib plus capecitabine in the treatment of unresectable hepatocellular carcinoma (HCC) to provide a more effective first-line treatment for patients with advanced HCC.

Methods

This open-label, prospective, phase II study included patients with unresectable HCC who did not receive systematic treatment. The patients were treated with sintilimab (200 mg, intravenous drip, once every 3 weeks) combined with apatinib (250 mg, oral administration, once a day) plus capecitabine (1000 mg/m², twice a day; after 2 weeks of oral administration, the drug was stopped for 1 week; course of treatment, 3 weeks). The primary endpoint was the objective response rate (ORR). The secondary endpoints included disease control rate (DCR), progression-free survival (PFS), duration of response (DoR), overall survival (OS), and safety.

Results

Forty-seven patients (1 lost to follow-up) were enrolled in the study. As of March 1, 2022, the ORR and DCR were 50.0% (95% CI: 34.9-65.1%) and 91.3% (95% CI: 79.2-97.6%), respectively, after blind, independent imaging evaluation. The median follow-up time was 18.7 months (95% CI: 17.2-20.2 months). The median PFS was 9.0 months (95% CI: 7.1-10.9 months). The median DoR was 10.8 months (95% CI: 4.8-16.8 months). The median OS was not reached, and the 1-year OS rate was 71.7% (95% CI: 56.5-84.0%). Only 28.3% (13/46) of patients had grade 3/4 treatment-related adverse events.

Conclusion

Sintilimab combined with apatinib plus capecitabine has good safety and anti-tumor activity as a first-line treatment for unresectable HCC. This is worthy of further multi-center, prospective, randomized, large-sample clinical studies.

Project description:BackgroundMicrosatellite stable (MSS) and RAS-mutant metastatic colorectal cancer (mCRC) patients are characterized by an immunosuppressive microenvironment and a low response rate to immunotherapy. Chemotherapy and anti-angiogenesis therapy have been reported to potentially promote immunotherapy response. This study aims to assess the preliminary anti-tumor activity and safety of sintilimab plus bevacizumab, oxaliplatin and capecitabine as a treatment option for patients with RAS-mutant MSS mCRC.MethodsThis study was an open-label, single-arm, phase II trial in China. Patients with unresectable, RAS-mutant and MSS metastatic colorectal adenocarcinoma received treatment by intravenous sintilimab (200 mg, day 1) plus bevacizumab (7.5 mg/kg, day 1), oxaliplatin (135 mg/m2, day 1) and oral capecitabine (1 g/m2, day 1-14) in each 21-day cycle. The primary endpoints included objective response rate (ORR) and adverse events. Biomarker analysis was performed to identify potential predictors of good response to treatment. This study is registered with ClinicalTrials.gov, number NCT04194359.FindingsBetween April 2021 and December 2021, 25 patients were enrolled. Two (8%) patients showed complete response (CR), 19 (76%) had partial response (PR) and 4 (16%) presented with stable disease. ORR reached 84% (95% CI, 63.9-95.5) and the disease control rate was 100% (95% CI, 86.3-100). The median progression-free survival (PFS) was 18.2 months for the full analysis set. The most common treatment-related adverse events (TRAEs) in all grades were anemia (21/25, 84%), neutropenia (20/25, 80%), and hand-foot syndrome (14/25, 56%). The most frequent grade 3 or 4 TRAEs were neutropenia (3/25, 12%) and increased alanine transaminase (2/25, 8%). No grade 5 adverse events occurred. In the exploration of biomarkers, 5 patients could be characterized as TTN/OBSCN "double-hit" after treatment, and the copy number variants burden was significantly decreased in tumor tissues after treatment compared with the baseline. Nanostring panel RNA sequencing analysis indicated a better tumor immune microenvironment cell infiltration in CR/PR patients compared with non-CR/PR patients as well as the PFS-long (≥12.5 months) group compared with the PFS-short group.InterpretationCombination treatment with sintilimab plus bevacizumab, oxaliplatin and capecitabine as first-line treatment demonstrated a promising antitumor activity and a manageable safety profile in RAS-mutant, MSS and unresectable mCRC. Exploratory biomarker assessment analysis showed that some RAS-mutant and MSS patients changed into "immune-hot" subtype after the treatment.FundingThis study was supported by the Key R&D Program of Zhejiang Province (2021C03125 to Ying Yuan), the National Natural Science Foundation of China (81872481 to Ying Yuan, 82072624 to Kefeng Ding), the Fundamental Research Funds for the Central Universities (No. 226-2022-00009 to Kefeng Ding), and the Zhejiang Provincial Natural Science Foundation of China (No. LY22H160024 to Hanguang Hu).

Project description:BackgroundAdding anti-angiogenics to neoadjuvant chemotherapy for localized gastric cancer is recognized as a promising strategy, but its clinical value remains to be defined.MethodsThis single-center, single-arm, phase 2 trial included patients with locally advanced (cT3/4aN+M0) adenocarcinoma of the stomach or gastroesophageal junction (GEJ) who received three cycles of intravenous oxaliplatin (135 mg/m2 on day 1), oral capecitabine (1000 mg/m2 twice daily on days 1 to 14), and oral apatinib for 21 days (250 mg once daily in the first two cycles, and further increased to 500 mg daily in the third cycle based on whether any adverse event of grade 3 or worse occurred), and an additional cycle of oxaliplatin plus capecitabine, followed by gastrectomy with D2 lymphadenectomy. The primary endpoint was the proportion of patients who achieved an objective response according to RECIST version 1.1.ResultsBetween April 28, 2017, and October 23, 2019, 37 patients were screened and 35 participants were included. Of the 32 patients assessable for efficacy and safety, objective responses were achieved in 25 (78.1%; 95% confidence interval [CI], 60.0% to 90.7%) patients. Thirty-one (96.9%) patients received R0 resection, two (6.3%) patients achieved pathological complete response, and 11 (34.4%) patients achieved pathological response. At the data cutoff date (September 30, 2021), the median event-free survival was 42.6 (95% CI, 16.2 to not reached) months, and the median overall survival was not reached. The most common grade 3 or 4 treatment-emergent adverse events were hypertension (9/32, 28.1%), thrombocytopenia (7/32, 21.9%), and neutropenia (5/32, 15.6%). Seven (21.9%) patients developed surgical complications, and the most common one was intra-abdominal abscess (4/32, 12.5%).ConclusionsThe concomitant use of apatinib, oxaliplatin, and capecitabine as neoadjuvant therapy showed promising efficacy and manageable safety profile in patients with locally advanced adenocarcinoma of the stomach or GEJ, and further phase 3 study is warranted.Trial registrationThis study was registered with ClinicalTrial.gov ( NCT03229096 ).

Project description:Lessons learnedPatient compliance with the oral dosage treatment was good, with no need for hospitalization. Patients with tracheal and esophageal fistulas can take crushed apatinib by nutrient tube, with the same bioavailability and efficacy. Apatinib may be an effective and safe second- or further-line treatment for advanced esophageal cancer.BackgroundApatinib is an inhibitor of vascular endothelial growth factor receptor-2 (VEGFR2), which is thought to play a role in esophageal cancer progression. Our goal was to evaluate the efficacy and safety of apatinib in patients with unresectable esophageal cancer and to examine whether VEGFR2 expression influenced the clinical response.MethodsThis single-arm, open-label, investigator-initiated phase II study enrolled patients with advanced squamous cell carcinoma (SCC) or adenocarcinoma of the esophagus or esophagogastric junction who were admitted to Tianjin Medical University Cancer Institute and Hospital between August 2017 and January 2019. Apatinib monotherapy (500 mg/day) was given orally or via an enteral tube until disease progression, unacceptable toxicity, withdrawal, or death. Patients were followed until treatment was discontinued or death. The main endpoints were tumor response, progression-free survival (PFS), overall survival (OS), and adverse events (AEs).ResultsAmong 32 patients screened for inclusion, 30 were included in the safety and survival analyses (i.e., received apatinib), and 26 were included in the efficacy analysis (at least one imaging follow-up). Median follow-up time and exposure to apatinib were 5.34 months and 72 days, respectively. Among 26 patients included in the efficacy analysis, 2 had a partial response (PR; 7.7%) and 14 had stable disease (SD; 53.8%). The overall response rate (ORR) was 7.7%, and the disease control rate (DCR) was 61.5%. Median PFS and OS were 4.63 months (95% confidence interval, 2.11-7.16 months) and 6.57 months (4.90 months to not estimable), respectively. Fifteen patients (50.0%) experienced treatment-related AEs, most commonly hypertension (26.7%), diarrhea (20.0%), and hand-foot-skin reaction (10.0%). No patients had grade ≥4 treatment-related AEs.ConclusionApatinib was effective as second- or further-line treatment for advanced esophageal cancer.

Project description:BackgroundThe integration of transarterial chemoembolization (TACE) with systemic therapy has demonstrated improved survival outcomes in patients with unresectable hepatocellular carcinoma (HCC). However, there is limited evidence evaluating the combination of TACE with the systemic regimen of anti-PD-1/L1 inhibitor plus lenvatinib. This study aims to assess the efficacy and safety of TACE combined with lenvatinib and sintilimab in unresectable HCC patients.MethodsUnresectable HCC patients who received TACE in combination with sintilimab plus Lenvatinib as first-line treatment from 1 January 2020 to 31 March 2023 were included for the analysis. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and disease control rate (DCR) were evaluated by modified Response Evaluation Criteria in Solid Tumors criteria. Exploratory biomarker analysis was conducted.ResultsThe study included 70 patients with unresectable HCC, predominantly male and infected with Hepatitis B. The median follow-up duration for the whole cohort was 13.8 months (95% CI 11.08-16.7). The ORR was 61.4% (95% CI, 49.0%-72.8%) and the DCR was 68.6% (95%CI, 56.4%-79.2%). The median PFS was 13.2 months (95% CI 11.0-NA), with a corresponding 1-year PFS rate of 50.3% (95% CI 39.7%-65.5%). The median OS was not reached, and the 1-year OS rate was 89.3% (95% CI 81.4%-97.9%). The most common treatment-related adverse events (TRAEs) were fatigue 38.6% (27/70), hypertension 32.9% (23/70), and hand-foot syndrome 31.4% (22/70). Most TRAEs were mild-to-moderate and manageable. In addition, significant predictive value was found in alpha-fetoprotein levels (AFP), with patients showing a level of decrease post-treatment having better PFS.ConclusionThe combination regimen demonstrated promising efficacy in treating unresectable HCC, accompanied by manageable safety profiles. Furthermore, the results of this investigation suggest that AFP holds promise as predictive biomarkers for this treatment strategy.

Project description:PurposeImmune checkpoint inhibitors combined with antiangiogenic therapy reportedly have potential synergistic antitumor activity. We investigated the activity and safety of this regimen for recurrent/metastatic nasopharyngeal carcinoma (NPC).MethodsThis single-arm, Simon two-stage study enrolled patients with recurrent/metastatic NPC who were refractory to at least first-line systemic therapy and treatment-naive to immune checkpoint inhibitors. The patients received camrelizumab 200 mg once every 3 weeks and apatinib 250 mg once per day. The primary end point was the objective response rate. Key secondary end points included disease control rate, progression-free survival, duration of response, overall survival, and safety.ResultsBetween October 14, 2020, and December 23, 2021, 58 patients were enrolled, and all were included in the efficacy and safety analysis set. The objective response rate was 65.5% (95% CI, 51.9 to 77.5), and the disease control rate was 86.2% (95% CI, 74.6 to 93.9). The median duration of response was not reached, and the median progression-free survival was 10.4 months (95% CI, 7.2 to 13.6), with a median follow-up duration of 12.4 months (range, 2.1-19.9 months). Treatment-related adverse events (TRAEs) of grade 3 or higher were reported in 34 (58.6%) patients, with the most common being hypertension (19.0%), nasopharyngeal necrosis (15.5%), headache (12.1%), AST elevation (10.3%), and creatine phosphokinase elevation (10.3%). Sixteen (27.6%) patients discontinued apatinib treatment before progression because of unbearable TRAEs, and the most common complication was nasopharyngeal necrosis (9/16; 56.3%). Recurrent nasopharyngeal lesions (odds ratio, 5.94 [95% CI, 1.45 to 24.24]) and reirradiation (odds ratio, 5.33 [95% CI, 1.15 to 24.79]) were significantly positively correlated with nasopharyngeal necrosis.ConclusionCamrelizumab plus apatinib had promising antitumor activity in patients with refractory recurrent/metastatic NPC who failed first-line therapy. Moderate to severe TRAEs were experienced by 58.6%, including nasopharyngeal necrosis associated with local recurrence and a history of reirradiation.
