The Efficacy and Safety Study of TORIPALIMAB INJECTION Combined With Chemotherapy for Nasophapyngeal Cancer

Phase 3
Conditions
Recurrent or Metastatic NPC
Interventions
Drug: Placebos
Biological: TORIPALIMAB INJECTION(JS001 ) combine with chemotherapy
Registration Number
NCT03581786
Lead Sponsor
Shanghai Junshi Bioscience Co., Ltd.
Brief Summary

This is a randomized, placebo-controlled, multi-center, double blinded, Phase III study to determine the efficacy and safety of TORIPALIMAB INJECTIO(JS001) in combination with gemcitabine/cisplatin compared with placebo in combination with gemcitabine/cisplatin as first-line treatment in patients with histological/cytological confirmation of recurrent or metastatic NPC. The primary endpoint is PFS in all patients. Approximately 280 patients who fulfill all of the inclusion criteria and none of the exclusion criteria will be randomized in a 1:1 ratio to one of the two treatment arms. patients will be randomly assigned to the combination of JS001 (Arm A) or placebo (Arm B) with gemcitabine and cisplatin given every 3 weeks (Q3W) in 3-week cycles.

Detailed Description

Total 289 patients were enrolled and randomized in a 1:1 ratio to the group of JS001 (Arm A) with gemcitabine and cisplatin or placebo (Arm B) with gemcitabine and cisplatin every 3 weeks (Q3W) in the 'during chemotherapy' phase. During the 'post-chemotherapy' phase, patients randomized to Arm A or Arm B will continue treatment with JS001 or placebo as maintenance therapy Q3W until excessive toxicity or progressive disease, withdrawal of consent or Investigator's judgement or a maximum of 2 years. Tumor evaluation scans will be performed at screening (as baseline) then every 6weeks in the first 12 months then every 9 weeks thereafter until objective disease progression. The primary objective is to compare PFS as assessed by the IRC in ITT population (all randomized patients).

Primary Outcome Measures
NameTimeMethod
IRC-assessed Progression-Free Survival (PFS) According to RECIST v1.1up to 2 years

To evaluate the efficacy of JS001 plus chemotherapy compared with placebo plus chemotherapy,as measured by IRC-assessed progression free survival (PFS) according to RECIST v1.1 in all patients.

The definition of Progressive Disease: At least a 20% increasein the sum of diameters of target lesions, taking as reference the smallest sum on study (thisincludes the baseline sum if that is the smallest on study). In addition to the relative increase of20%, the sum must also demonstrate an absolute increase of at least 5 mm. or the appearance of one or more new lesions is also considered progression.
