Project description:The incidence and mortality of colorectal cancer in China’s cancer disease spectrum is on the rise, and it is a common malignant tumor that harms the health of Chinese residents.In patients with synchronous metastatic colorectal cancer, RAS status is highly consistent in primary focus and metastasis, so NCCN guidelines recommend RAS testing of primary or metastatic tissue is feasible .However, there are also some reports that the difference of RAS status between primary and metastatic lesions was up to 22%.In additiont,there are few studies on whether the gene profile of the metastatic lesion is the same as that of the primary lesion in patients with postoperative heterogeneous metastasis in patients with stage III colorectal cancer.

Project description:Background: Camrelizumab (SHR1210) is a high-affinity, humanized immunoglobulin programmed cell death 1 (PD-1) monoclonal antibody. It was developed by Jiangsu Hengrui Medicine Co. Ltd. and has been approved for relapsed or refractory classical Hodgkin lymphoma patients and hepatocellular carcinoma patients in China. Apatinib is an orally administered vascular endothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase inhibitor and has been approved for advanced gastric adenocarcinoma or gastroesophageal junction adenocarcinoma in China. Camrelizumab alone and its combination with apatinib have been used in the treatment of various solid cancers. Methods: We searched Embase, PubMed, and other databases with the keyword “camrelizumab” or “SHR1210,” and evaluated the safety and efficacy data of the involved studies. Adverse events (AEs) mentioned in at least two studies were summarized, including any grade and grade ≥3 treatment-related AEs. Meanwhile, efficacy data were collected, such as overall response rate (ORR), disease control rate (DCR), duration of response, 6-month progression-free survival (PFS) rate, median PFS time, 12-month overall survival rate, and median overall survival time. Results: The major AEs of camrelizumab alone were reactive cutaneous capillary endothelial proliferation, fatigue, aspartate aminotransferase increase, proteinuria, pruritus, and alanine transaminase increase. The ORR and DCR were 20.2% (95% CI: 15.1–26.6%, p = 0.000, I2 = 70.360) and 45.8% (95% CI: 39.0–52.7%, p = 0.256, I2 = 58.661), respectively. In the three studies of combination therapy, two studies were combined with apatinib and one combined with chemotherapy. For these studies, common AEs were hypertension, platelet count decrease, nausea, proteinuria, aspartate aminotransferase increase, and white blood cell count decrease. The pooled ORR, DCR, and 6-month PFS rate were 41.8% (95% CI: 29.7–54.9%, p = 0.220, I2 = 86.265), 82.4% (95% CI: 75.9–87.4%, p = 0.000, I2 = 55.207), and 56.2% (95% CI: 35.8–74.6%, p = 0.559, I2 = 79.739), respectively. Conclusion: Camrelizumab and its combination are tolerable and appear to be efficient in treating numerous solid cancers. The combination therapy appears to have better efficacy with durable toxicity. However, these remain to be shown in future studies. Besides, baseline lactate dehydrogenase, programmed cell death ligand 1 (PD-L1) expression, tumor mutation burden, and the incidence of reactive cutaneous capillary endothelial proliferation may be efficacy predictors and need to be clarified in further studies.

Project description:Gallbladder carcinoma (GBC) with proficient mismatch repair (pMMR)/microsatellite stable (MSS) is associated with limited response to programmed death-1 (PD-1) inhibitor monotherapy. Limited data of PD-1 blockade combined with anti-angiogenic therapy in GBC are reported. One recurrent GBC patient with pMMR/MSS was treated with camrelizumab plus apatinib. After 4 cycles of combination therapy, the patient achieved a durable complete response with manageable toxicity. The next-generation sequencing and immunohistochemistry analysis showed that tumor mutation burden (TMB) was 7.26 mutants/Mb and PD-L1 expression was 10% (tumor proportion score) and 20% (immune proportion score). This case suggests that camrelizumab in combination with apatinib may be an effective treatment option for GBC patients with pMMR/MSS status, who have moderate expression of TMB and PD-L1. Additionally, TMB and PD-L1 expression may serve as potential biomarkers for predicting PD-1 inhibitor response of GBC. Furthermore, this needs to be verified in future studies.

Project description:PurposeCamrelizumab is an antibody against programmed death protein 1. We assessed the activity and safety of camrelizumab plus apatinib, a tyrosine kinase inhibitor of vascular endothelial growth factor receptor-2, in patients with advanced cervical cancer.MethodsThis multicenter, open-label, single-arm, phase II study enrolled patients with advanced cervical cancer who progressed after at least one line of systemic therapy. Patients received camrelizumab 200 mg every 2 weeks and apatinib 250 mg once per day. The primary end point was objective response rate (ORR) assessed by investigators per RECIST version 1.1. Key secondary end points were progression-free survival (PFS), overall survival (OS), duration of response, and safety.ResultsForty-five patients were enrolled and received treatment. Median age was 51.0 years (range, 33-67 years), and 57.8% of patients had previously received two or more lines of chemotherapy for recurrent or metastatic disease. Ten patients (22.2%) had received bevacizumab. Median follow-up was 11.3 months (range, 1.0-15.5 months). ORR was 55.6% (95% CI, 40.0% to 70.4%), with two complete and 23 partial responses. Median PFS was 8.8 months (95% CI, 5.6 months to not estimable). Median duration of response and median OS were not reached. Treatment-related grade 3 or 4 adverse events (AEs) occurred in 71.1% of patients, and the most common AEs were hypertension (24.4%), anemia (20.0%), and fatigue (15.6%). The most common potential immune-related AEs included grade 1-2 hypothyroidism (22.2%) and reactive cutaneous capillary endothelial proliferation (8.9%).ConclusionCamrelizumab plus apatinib had promising antitumor activity and manageable toxicities in patients with advanced cervical cancer. Larger randomized controlled trials are warranted to validate our findings.

Project description:BackgroundPD-1/L1 inhibitor-based immunotherapy is currently under investigation in biliary tract cancer (BTC). Apatinib combined with camrelizumab has achieved promising results in various tumor types. The aim of this study was to assess the safety and efficacy of apatinib plus camrelizumab for advanced biliary tract cancer patients who have received previously treatments.MethodsThis prospective, non-randomized, open-label trial was conducted at Peking Union Medical College Hospital (PUMCH). All included patients received apatinib orally at 250 mg per a day and camrelizumab intravenously at 200 mg every three weeks until disease progression or intolerable toxicity occurred. Efficacy was evaluated based on the Response Evaluation Criteria in Solid Tumors RECIST Version 1.1 (RECIST 1.1). Adverse events (AEs) were assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE version 4.0).ResultsA total of 22 patients were consecutively enrolled from 1st December, 2018 until 1st August, 2020. Among 21 patients for whom we could conduct efficacy evaluations, no patients achieved a complete response (CR), 4 patients (19%) achieved partial response (PR), and 11 patients had stable disease with a disease control rate of 71.4%. The median overall survival was 13.1 months (95% CI, 8.1-18.2), and the median progression-free survival was 4.4 months (95% CI, 2.4-6.3). All patients experienced treatment related AEs, and grade 3 or 4 AEs occurred in 14 (63.6%) of 22 patients. No treatment related deaths were observed.ConclusionsThis is the first report focusing on the efficacy and safety of camrelizumab plus apatinib in pretreated biliary tract cancer patients. The finding suggests this regimen has favorable therapeutic effects with relatively manageable toxicity. Further trials with a control arm are required to investigate.Clinical trial registrationidentifier NCT04642664.

Project description:In the REGONIVO study, regorafenib combined with nivolumab was effective in the treatment of microsatellite stable (MSS) metastatic colorectal cancer (mCRC), which indicated anti-angiogenic drugs may enhance the efficacy of immune checkpoint inhibitors. Therefore, we designed a single-arm, single-center, open-label, phase II trial to determine the toxicity and efficacy of SHR-1210 (an anti-PD-1 antibody) plus apatinib in MSS mCRC. The sample size was estimated using a Simon Optimum two-stage design. 10 patients were included at the first stage and if one effective patient observed, an additional 19 patients would be added. Patients with MSS mCRC who refractory to second-line treatment or intolerant to standard treatment were given SHR-1210 200 mg every 2 weeks and apatinib 250-375 mg once daily until unacceptable toxicity or disease progression occurred. In our study, the objective response rate was 0% and the disease control rate was 22.2%. The median progression-free survival was 1.83 months (95% confidence interval (CI) 1.80-1.86 months), and the median overall survival was 7.80 months (95% CI 0-17.07). Treatment-related adverse events (AEs) occurred in all patients (100%). The most common treatment-related AEs were hypertension and proteinuria (70% each). Grade 3 AEs were observed in nine patients (9/10, 90%), and the commonest was hypertension (30%). In conclusion, SHR-1210 combined with apatinib has failed to improve the efficacy of treatment of MSS mCRC, and the intolerable toxicity may be the leading cause.

Project description:BackgroundHepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT) has poor prognosis. Sorafenib/lenvatinib is recommended as the first-line therapy in these patients currently, with unsatisfactory response and survival benefit reported. Radiotherapy (RT) is increasingly utilized in advanced HCC and is considered an alternative option for HCC patients with PVTT. Combined treatment of RT and locoregional treatments such as transarterial chemoembolization shows promising results. However, the efficacy and safety for combined treatment of RT and systemic therapy have not been reported and thus warrant further studies. This prospective clinic trial aims at evaluating the efficacy and safety of stereotactic body RT (SBRT) combined with camrelizumab and apatinib in HCC patients with PVTT.MethodsThis multicenter, open-label, randomized controlled trial will enroll 264 HCC patients with PVTT who have not received systemic therapy previously. Stratification of patients will be based on the presence or absence of extrahepatic metastasis and level of AFP (AFP ≥ 400 or <400 ng/mL) and randomly assigned 1:1 to study and control groups. Patients in study group will receive SBRT (95% PTV 36-40 Gy/6-8 Gy), camrelizumab (200 mg every 3 weeks), and apatinib (250 mg every day), and patients in control group will receive camrelizumab (200 mg every 2 weeks) and apatinib (250 mg every day). Patients will be followed up for 1.5 to 3.5 years since the start of therapy. We will use overall survival as the primary endpoint and progression-free survival, objective response rate, disease control rate, adverse events, and quality of life as the secondary endpoints.DiscussionThis study will be the first randomized controlled trial to assess the efficacy and safety of SBRT combined with camrelizumab and apatinib for HCC patients with PVTT. The results may help establish a new standard first-line therapy for these patients.Trial registrationChinese Clinical Trial Registration No. ChiCTR1900027102.Date of registrationOctober 31, 2019.

Project description:BackgroundEffective therapeutic options are limited for patients with advanced esophageal squamous cell carcinoma (ESCC). The incorporation of an immune checkpoint inhibitor and a molecular anti-angiogenic agent into the commonly adopted chemotherapy may produce synergistic effects. Therefore, we aimed to investigate the efficacy and safety of camrelizumab plus apatinib combined with chemotherapy as the first-line treatment of advanced ESCC.MethodsIn this single-arm prospective phase II trial, patients with unresectable locally advanced or recurrent/metastatic ESCC received camrelizumab 200 mg, liposomal paclitaxel 150 mg/m2 , and nedaplatin 50 mg/m2 on day 1, and apatinib 250 mg on days 1-14. The treatments were repeated every 14 days for up to 9 cycles, followed by maintenance therapy with camrelizumab and apatinib. The primary endpoint was objective response rate (ORR) according to the Response Evaluation Criteria in Solid Tumors (version 1.1). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety.ResultsWe enrolled 30 patients between August 7, 2018 and February 23, 2019. The median follow-up was 24.98 months (95% confidence interval [CI]: 23.05-26.16 months). The centrally assessed ORR was 80.0% (95% CI: 61.4%-92.3%), with a median duration of response of 9.77 months (range: 1.54 to 24.82+ months). The DCR reached 96.7% (95% CI: 82.8%-99.9%). The median PFS was 6.85 months (95% CI: 4.46-14.20 months), and the median OS was 19.43 months (95% CI: 9.93 months - not reached). The most common grade 3-4 treatment-related adverse events (AEs) were leukopenia (83.3%), neutropenia (60.0%), and increased aspartate aminotransferase level (26.7%). Treatment-related serious AEs included febrile neutropenia, leukopenia, and anorexia in one patient (3.3%), and single cases of increased blood bilirubin level (3.3%) and toxic epidermal necrolysis (3.3%). No treatment-related deaths occurred.ConclusionsCamrelizumab plus apatinib combined with liposomal paclitaxel and nedaplatin as first-line treatment demonstrated feasible anti-tumor activity and manageable safety in patients with advanced ESCC. Randomized trials to evaluate this new combination strategy are warranted.Trial registrationThis trial was registered on July 27, 2018, at ClinicalTrials.gov (identifier: NCT03603756).

Project description:Immunotherapy by immune checkpoint inhibitors (ICIs) has showed outstanding efficacy in the treatment of advanced non-small cell lung cancer (NSCLC). The combination of immunotherapy with anti-angiogenic therapy exhibited enhanced efficacy in multiline treatment. However, the potential biomarkers for predicting and monitoring the therapeutic response of the combined therapy remain undefined. In this study, we performed a pilot study by prospectively recruiting 22 advanced NSCLC patients who failed to previous lines of chemotherapy, chemoradiotherapy, TKI therapy, surgery, or any combination of the therapies, and investigated the prognostic factors for patients who received anti-PD-1 (Camrelizumab) and anti-angiogenic (Apatinib) combined therapy. The objective response rate (ORR) assessed by an independent radiology review was 22.7%, and the median progression-free survival (PFS) was 5.25 months. We found that high concentration of circulating-free DNA (cfDNA) (HR = 27.75, P = 0.003), MIKI67 mutation (HR = 114.11, P = 0.009) and gene variations related to hyper-progressive disease (HPD) (HR = 36.85, P = 0.004) were independent risk factors and exhibited significant correlation with PFS. Circulating tumor DNA (ctDNA) mutational status was also a predicting indicator for PFS. In contrast, the blood tumor mutational burden (bTMB) could not stratify the clinical benefit in this combined therapy (HR = 0.81, P = 0.137). Furthermore, we found that the variant allele fraction (VAF) of mutations in ctDNA was sensitive indicators of therapeutic response and therefore can be used to monitor the tumor relief or progression. In conclusion, cfDNA concentration, MIKI67 mutations and HPD-related mutations were independent risk factors and PFS predictors for multiline combined anti-angiogenic/ICI combined therapy. ctDNA may be a novel monitoring biomarker for therapeutic response and predicting biomarker for prognosis in future combined therapy involving PD-1 blockade.

Project description:BackgroundA small proportion of patients with advanced esophageal squamous cell carcinoma (ESCC) could benefit from immune checkpoint inhibitors; however, reliable peripheral blood biomarkers for outcomes of anti-PD-1 immunotherapy in ESCC have not been identified.MethodsThe data of 43 patients in the ESCC cohort of a phase I trial at our center were retrospectively reviewed. All patients were administered intravenous camrelizumab (SHR-1210), a novel anti-PD-1 antibody, at doses of 60 mg, 200 mg, or 400 mg (4-week interval after first dose followed by a 2-week schedule) until disease progression or intolerable toxicity. Associations between lactate dehydrogenase (LDH) and other peripheral blood biomarkers at baseline and the efficacy of camrelizumab were also investigated.ResultsAfter median follow-up of 19.6 months, the overall response rate was 25.6% (11/43), including one complete response. Median progression-free and overall survival rates were 2.0 and 8.0 months, respectively. Patients with an elevated baseline LDH had lower tumor response rates (P = 0.02) and shorter progression-free (P = 0.002) and overall (P < 0.0001) survival than patients with normal LDH levels. An increase in LDH levels during treatment was significantly associated with disease progression. Multivariate Cox analysis identified LDH (hazard ratio [HR] 0.18), CRP (HR 0.27), the number of organs involved (HR 0.31), absolute monocyte count (HR 0.33), and Eastern Cooperative Oncology Group performance status (HR 0.36) as independent prognostic factors.ConclusionsSerum LDH, which is readily available in routine clinical practice, is a potential marker for response and a powerful independent factor for survival in advanced ESCC patients treated with anti-PD-1 therapy.
