Actual date on which the first participant was enrolled.

This study is a parallel 3-arm escalation trial with 3 doses of HLX07 (400 mg, 600 mg, or 800 mg per single dose) combined with 3 different fixed-dose chemotherapy regimens. Three chemotherapy regimens are： ① Gemcitabine (1000 mg/m2) and Cisplatin (75 mg/m2) , every three weeks. Gemcitabine was administered on the first day and on the 8th day, and cisplatin 75 mg/m2 was administered on the first day , a total of 4-6 cycles。 ② Paclitaxel (80 mg/m2) and carboplatin (AUC=2), every 3 weeks. Paclitaxel and carboplatin were administered on days 1, 8 and 15 for a total of 4-6 cycles. ③ mFOLFOX6 protocol: oxaliplatin (85 mg/m2), leucovorin (400 mg/m2), and 5-fluouracil (5-FU) (400 mg/m2, followed by 2400 mg/m2), every 2 weeks. Oxaliplatin, leucovorin and 5-FU were administered on the first day. After 4 to 6 cycles of (gemcitabine and cisplatin regimens) and (the paclitaxel and carboplatin regimens) or after 6 to 12 cycles of the mFOLFOX6 regimen, well-controlled patients will be continue to receive a weekly HLX07 infusion as maintenance therapy for maximum 2 years or until disease progression or emergence of intolerable toxicity or permanent withdrawal or death (whichever comes first). The study used the Bayes optimal interval design (BOIN) to determine the MTD of HLX07 in combination with chemotherapy.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

56 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Treatment Study

These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

Any sex

Biological sex of participants that are eligible to enroll.

From 18 to 75 Years

Range of ages for which participants are eligible to join.

Healthy volunteers not allowed

If individuals who are healthy and do not have the condition being studied can participate.

Criteria

11 inclusion criteria required to participate

At least 28 days from prior major surgery, prior cytotoxic chemotherapy, or prior therapy with investigational agents or local radiotherapy and at least 42 days from the last infusion of immune check point inhibitors (The antibodies or drugs include but not limited to IDO, PD-1, PD-L1, IL-2R, CTLA-4, CD137, and GITR) before the first infusion of investigational product.

Eastern Cooperative Oncology Group (ECOG) score ≤ 1.

Expected survival time ≥ 3 months.

Has sufficient hematological function, defined as: neutrophil absolute value ≥ 1.5 × 109 / L; hemoglobin level ≥ 9.0 g / dL ; Platelet count ≥100×109 /L.

Show More Criteria

12 exclusion criteria prevent from participating

Unstable central nervous system (CNS) metastasis. Patients who have previously undergone surgery or radiotherapy for brain metastases may participate in this study if they are clinically stable for at least 4 weeks and has stopped steroids for at least 2 weeks prior to the first infusion of the test drug and there is no new evidence of progression.

Primary central nervous system malignancy.

Known patients have drug allergies to specific drug regimens (eg anti-EGFR monoclonal antibodies, gemcitabine, platinum, paclitaxel, fluorouracil allergy).

Known active hepatitis B or C infection (active hepatitis B is defined as hepatitis B surface antigen HBsAg positive and Hepatitis B virus (HBV) DNA> 500 copies / ml; active hepatitis C is defined as hepatitis C antibody-positive and / or quantitative Hepatitis C virus (HCV) RNA results positive).

Treatment Groups

Study Objectives

3 intervention groups are designated in this study

This study does not include a placebo group

Treatment Groups

Group I

Experimental

HLX07 is given on D1,D8,D15 combine with Gemcitabine (1000 mg/m2) and Cisplatin (75 mg/m2) in 3 weeks- cycles for 4-6 cycles .Gemcitabine was administered on the D1 and D8 and cisplatin 75 mg/m2 was administered on the D1. After 4-6 cycles of combination therapy, once weekly HLX07 infusion will be continue for a maximum duration of 2 years or until disease progression or emergence of intolerable toxicity or permanent withdrawal or death (whichever comes first). In each cohort, HLX07 will use BOIN design to assign the subject's dose level and determine the MTD.

Group II

Experimental

HLX07 is given on D1,D8,D15 combine with Paclitaxel (80 mg/m2) and carboplatin (AUC=2) in 3 weeks-cycle for 4-6 cycles .Paclitaxel and carboplatin were administered on D1, D8 and D15. After 4-6 cycles of combination therapy, once weekly HLX07 infusion will be continue for a maximum duration of 2 years or until disease progression or emergence of intolerable toxicity or permanent withdrawal or death (whichever comes first). In each cohort, HLX07 will use BOIN design to assign the subject's dose level and determine the MTD.

Group III

Experimental

HLX07 is given on D1,D8 combine with mFOLFOX6 ( oxaliplatin (85 mg/m2), leucovorin (400 mg/m2), and 5-FU (400 mg/m2, followed by 2400 mg/m2) in 2 weeks-cycles for 6-12 cycles . Oxaliplatin, leucovorin and 5-FU were administered on D1. After 6-12 cycles of combination therapy,once weekly HLX07 infusion will be continue for a maximum duration of 2 years or until disease progression or emergence of intolerable toxicity or permanent withdrawal or death (whichever comes first). In each cohort, HLX07 will use BOIN design to assign the subject's dose level and determine the MTD.
