A Study to Evaluate the Efficacy and Safety of Toripalimab Injection in the Treatment of Recurrent or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma Who Have Failed at Least Two Prior Lines of Therapy and Are Positive Specific Markers

Phase 2
Conditions
Recurrent or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma Who Have Failed at Least Two Prior Lines of Therapy
Interventions
Registration Number
NCT04603040
Lead Sponsor
Shanghai Junshi Bioscience Co., Ltd.
Brief Summary

This is a single-arm, multicenter, phase 2 study to assess the efficacy and safety of Toripalimab Injection (JS001) in patients with advanced recurrent or metastatic gastric or gastroesophageal junction adenocarcinoma who have failed at least 2 prior lines of therapy and are positive for specific markers.

Patients who meet the requirements will be treated with Toripalimab injection 240 mg once every 3 weeks (q3w) until disease progression based on imaging according to RECIST 1.1 criteria judged by the investigator, or intolerable toxicity, or withdrawal of informed consent, or withdrawal of treatment judged by the investigator, or voluntarydiscontinuation of treatment by the patient with CR of more than 6 months, or up to 2 years of treatment for JS001, whichever occurs first.

For the case that the patient shows disease progression on imaging according to RECIST 1.1, as long as the investigator judges that the patient can still benefit from continued medication, the treatment with Toripalimab Injection can be continued until the progression on imaging assessed by the investigator for the second time. The clinical benefit is based on the results of comprehensive assessment by the investigator in combination with imaging findings and clinical condition when the patient has no intolerable toxicity or the symptoms worsen due to disease progression.

Tumor assessments are performed at screening (as the baseline), every 6 weeks from the first dose in the first year, and every 9 weeks from the second year until radiologically documented progressive disease (PD), or second disease progression judged by the investigator (for patients with disease progression shown by first imaging, but who can continue treatment judged by the investigator), or withdrawal of informed consent by the patient, or loss to follow-up, or start of a new anti-tumor therapy, or the termination of the study. If a patient withdraws from the study for reasons other than disease progression (including due to the AE or because the treatment interval is beyond the window) and no disease progression occurs at the time of withdrawal, radiographic assessments should be continued until disease progression, death, or start of a new anti-tumor therapy. Patient medication management is based on the investigator's tumor assessment.

Secondary Outcome Measures
NameTimeMethod
IPFSUp to 12 months

IPFS is defined as the time from enrollment to the first documentation of disease progression or death from any cause, whichever occurs first;

DCRUp to 12 months

DCR is defined as the proportion of patients with best response of CR or PR or stable disease (SD);

iORRUp to 12 months

iORR is defined as the proportion of subjects with best response of CR or PR;

iDCRUp to 12 months

iDCR is the proportion of patients with best response of CR or PR or SD;

DoRUp to 12 months

DoR is defined as the time from the first documented response until the first documented evidence of disease progression or death from any cause, whichever occurs first;

PFSUp to 12 months

PFS is defined as the time from enrollment to the first documentation of disease progression or death from any cause, whichever occurs first;

iDoRUp to 12 months

iDoR is the time from the first documented response until the first documented evidence of disease progression or death from any cause, whichever occurs first;

Overall survival (OS)Up to 12 months

Overall survival (OS), defined as the time from enrollment to death of the patient from any cause.

Objective response rate (ORR)Up to 12 months

ORR assessed by the investigator according to RECIST v1.1 assessment criteria. ORR is defined as the proportion of subjects with best response of CR or PR.

PFS rates at 6 and 12 monthsUp to 12 months

It is defined as the proportion of patients alive without documented disease progression at 6 and 12 months after enrollment assessed by RECIST v1.1 criteria

OS rates at 9 months and 12 monthsUp to 12 months

defined as the proportion of patients alive at 9 months and 12 months after enrollment.
