Study of First-line Camrelizumab With or Without Chemotherapy for Advanced Esophageal Squamous Cell Cancer
- Registration Number
- NCT04654403
- Lead Sponsor
- The First Affiliated Hospital of Zhengzhou University
- Brief Summary
The purpose of this study is to evaluate the efficacy and safety of Camrelizumab or Camrelizumab plus chemotherapy in patients with untreated, advanced ESCC with PD-L1 CPS≥10 ,who have been achieved PR and CR after treated with Camrelizumab.
- Detailed Description
Standard 1L chemotherapy for advanced or metastatic esophageal squamous cell cancer(ESCC) results in poor OS(median\<1year).Camrelizumab provided superior OS versus chemotherapy in heavily pretreated advanced/rucurrent ESCC.PD-1 antibody +chemo showed promisng antitumor activity in 1L advanced or metastatic ESCC.PD-L1 expression by CPS at cutoff≥10 has shown better enrichment for efficacy fo checkpoint inhibitors in ESCC.Recently, two clinical trials on Pembrolizumb have attracted our attention,KEYNOTE-181 and KEYNOTE-590.The median duration of response was 9.3 months in pembrolizumab monotherapy (KEYNOTE-181) ,and 8.3 months in Pembrolizumb plus chemotherapy (KEYNOTE-590). We hypothesis that administration of the PD-1 inhibitor will significantly prolong survival compared to PD-1 inhibitor combined with chemotherapy, when used as maintenance therapy in patients sensitive to PD-1 inhibitors.

Group Intervention Description Camrelizumab Camrelizumab Camrelizumab (200 mg every 2 weeks),Treatment will continue until confirmed radiographic progression,unacceptable toxicity, investigator or patient decision to withdraw, nonadherence to treatment or trial procedures or completion of 16 cycles of Camrelizumab (approximately 1 years) Camrelizumab plus chemotherapy Camrelizumab Camrelizumab plus chemotherapy(Camrelizumab 200 mg every 3 weeks,docetaxel 75mg/m2/d plus cisplatin 75 mg/m2/d on day 1 every 3 weeks),)Treatment will continue until confirmed radiographic progression,unacceptable toxicity, investigator or patient decision to withdraw, nonadherence to treatment or trial procedures or completion of 16 cycles of Camrelizumab (approximately 1 years).
- Primary Outcome Measures
Name Time Method DOR Up to 12 months DOR was defined as the time from the first documented a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) to progressive disease (PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of ≥5 mm. The appearance of ≥1 new lesions was also considered PD) as assessed using RECIST v1.1.Median DOR as assessed by blinded independent central review per RECIST 1.1 is presented for participants who receive Camrelizumab with or without chemotherapy for advanced esophageal squamous cell cancer with a PD-L1 CPS ≥10.
- Secondary Outcome Measures
Name Time Method OS Up to 24 months OS was defined as the time from randomization to death due to any cause. Median OS in participants who receive Camrelizumab with or without chemotherapy for advanced esophageal squamous cell cancer with a PD-L1 CPS ≥10.
PFS Up to 12 months PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also have demonstrated an absolute increase of ≥5 mm. The appearance of ≥1 new lesions was also considered PD. Median PFS as assessed by blinded independent central review per RECIST 1.1 is presented for participants who receive Camrelizumab with or without chemotherapy for advanced esophageal squamous cell cancer with a PD-L1 CPS ≥10.
ORR Up to 12 months ORR was defined as the percentage of participants who had a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) as assessed using RECIST 1.1. The percentage of participants with SCC of the esophagus who experienced a CR or PR is presented.
