About

To evaluate the safety, efficacy and immunogenicity of SCT510 combined with paclitaxel and carboplatin compared with bevacizumab combined with paclitaxel and carboplatin in the first-line treatment of locally advanced metastatic or recurrent squamous cell non-small cell lung cancer.

Full description

A randomized, double-blind, parallel-controlled, multicenter phase 3 clinical trial.

560 patients with non-resectable locally advanced, metastatic or recurrent non-squamous cell non-small cell lung cancer (NSCLC) were randomly divided into two groups (SCT510 group and bevacizumab group) at a 1:1 ratio, and the treatment included combination chemotherapy and maintenance treatment, followed by follow-up.

Enrollment: 560 estimated patients

Sex: All

Ages: 18 to 80 years old

Volunteers: No Healthy Volunteers

4. It is able to provide relevant documents about EGFR mutation and ALK fusion gene status, and there is no EGFR sensitive mutation (including exon mutation no. 18 (G719X), exon deletion no. 19 and exon mutation no. 21 (L858R, L861Q)) and ALK fusion.Subjects who have not previously undergone EGFR and ALK gene testing will need to undergo genetic testing during the screening period.Among them, subjects whose EGFR or ALK gene status cannot be determined for various reasons can be enrolled;Subjects who are known to have EGFR sensitive mutations and/or ALK fusion may also be enrolled if they are currently unable to obtain the corresponding targeted drugs (including the rejection of the subjects) and chemotherapy is standard treatment at the research center;

5. According to RECIST v1.1 criteria, at least one measurable lesion was ensured;The lesions that had received radiotherapy before could only be selected as target lesions if there was clear disease progression 3 months after the end of radiotherapy.

6. Systemic antitumor therapy for locally advanced metastatic or recurrent non-squamous non-small cell lung cancer has not been accepted.If the subjects in the complete early non-small cell lung cancer after radical treatment received adjuvant therapy, and disease relapse, participants need to ensure that adjuvant therapy over time from this study first dosing interval more than 6 months, and auxiliary treatment led to a variety of toxic effects have been restored (according to the CTCAE v4.03 standard judgment level 1 or less, except for hair loss).

   • liver function: total bilirubin (TBil) < 1.5 times the normal upper limit; Aspartate aminotransferase(AST/SGOT),Alanine aminotransferase (ALT/SGPT),andalkaline phosphatase(ALP) < 2.5 times the normal upper limit;In the case of liver metastasis, AST and ALT were less than or equal to 5.0 times the upper limit of normal values.In the case of liver metastasis and/or bone metastasis, ALP is less than or equal to 5.0 times the normal upper limit.
   • renal function: upper limit of normal serum creatinine (Scr) less than 1.5 times;
   • urine protein < 2 (+) detected by routine urine test;If the urine protein at baseline is greater than or equal to 2 (+), the 24-hour urine protein quantification must be less than or equal to 1.0 g.
   • coagulation function: the international standardized ratio (INR) is no more than 1.5, and the activation time of partial thrombin (APTT) is no more than 1.5 times the upper limit of normal value;

10. Heart function: left ventricular ejection fraction (LVEF) 50% or higher;

11. able to communicate well with researchers and follow the visit, treatment, laboratory examination and other relevant regulations stipulated in the study.
