About

This study is a prospective, exploratory Phase II clinical study aimed at evaluating the safety and efficacy of Envafolimab and recombinant human endostatin and Recombinant Human Adenovirus Type 5 Intratumor local injection combined with systemic therapy in patients with locally advanced or advanced non-small cell lung cancer(NSCLC).

Full description

This study is a prospective, exploratory Phase II clinical study aimed at evaluating the safety and efficacy of Envafolimab and recombinant human endostatin and Recombinant Human Adenovirus Type 5 Intratumor local injection combined with systemic therapy in patients with locally advanced or advanced non-small cell lung cancer(NSCLC).

Patients with pathologically confirmed unresectable locally advanced/advanced NSCLC with atelectasis were screened and eligible subjects were randomized to receive local intratumoral injection of envolumab/Endostar/recombinant human adenovirus type 5 H101 combined with systemic therapy after signing informed consent.

Enrollment: 84 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

3. Histologically or cytologically confirmed advanced or metastatic locally advanced, advanced (Stage IIIB, IIIC, or IV) NSCLC without mutations in driver gene testing;
4. Patients with recurrent or metastatic NSCLC who have previously failed first-line standard therapy;
5. According to Response Evaluation Criteria in Solid Tumors (RECIST1.1), there should be at least one measurable lesion as a target lesion, and the measurable lesion should not have received local therapy such as radiotherapy;
6. Atelectasis Radiographically assessed atelectasis with at least one lobe;
7. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1;
8. Expected survival ≥3 months;
9. Major organ functions within 7 days prior to treatment meeting the following criteria:(1) Blood routine examination criteria (without blood transfusion within 14 days) : ① Hemoglobin (HB) ≥90g/L; ② absolute neutrophil count (ANC) ≥1.5×10^9/L; ③ Platelet (PLT) ≥80×10^9/L. (2) Biochemical examination should meet the following criteria: ① Total bilirubin (TBIL) ≤1.5 times the upper limit of normal (ULN); ② Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)≤2.5×ULN, if accompanied by liver metastasis, ALT and AST≤5×ULN; ③ Serum creatinine (Cr) ≤1.5×ULN or creatinine clearance (CCr)≥60ml/min; ④ Serum albumin ≥35g/L. (3) Doppler ultrasound assessment: Left ventricular ejection fraction (LVEF)≥lower limit of normal (50%).
10. For female subjects of childbearing potential, a negative urine or serum pregnancy test should be obtained 3 days prior to receiving the first dose of study drug;
11. Subject and subject sexual partner need to use contraceptive measures (eg intrauterine device, contraceptive pill , or condom) during the study treatment period and for 6 months after the end of the study treatment period;

Exclusion criteria

1. Severe metamorphosis/allergic reaction to humanized antibodies or fusion proteins;
2. Known hypersensitivity to Endostar or any component of the antibody formulation;
3. Diagnosis of immunodeficiency or ongoing systemic glucocorticoid therapy or any other form of immunosuppressive therapy within 14 days prior to the first dose of study, physiological doses of glucocorticoids (≤ 10 mg/day prednisone or equivalent) are permitted;
4. Exclude subjects with active, known, or suspected autoimmune diseases (such as interstitial pneumonia, colitis, hepatitis, pituitaritis, vasculitis, nephritis, hypothyroidism, including but not limited to these diseases or syndromes). Subjects who have type 1 diabetes, hypothyroidism requiring hormone replacement therapy, skin conditions that do not require systemic treatment (e.g., vitiligo, psoriasis, or hair loss), or conditions that are not expected to recur in the absence of external triggers may be enrolled;
5. Patients with severe heart disease, including congestive heart failure, uncontrolled high-risk arrhythmia, unstable angina pectoris, myocardial infarction, severe heart valve disease;

7. Systemic anti-tumor therapy, including cytotoxic therapy, signal transduction inhibitors, immunotherapy (or mitomycin C within 6 weeks prior to receiving trial drug) planned within 4 weeks prior to group assignment or during this study. Expansion field radiotherapy (EF-RT) within 4 weeks before grouping or limited field radiotherapy to assess tumor lesions within 2 weeks before grouping;
8. Active hepatitis B (HBV DNA ≥ 2000IU/ml or 104copies/ml), hepatitis C (hepatitis C antibody positive and HCV-RNA higher than the lower limit of assay);
9. Active pulmonary tuberculosis (TB) infection was judged based on chest X-ray, sputum examination, and clinical examination. Patients with a history of active pulmonary tuberculosis infection within the previous year, even if treated, were excluded; patients with a history of active pulmonary tuberculosis infection more than 1 year ago, unless the course and type of anti-tuberculosis treatment previously used were proven to be appropriate.

14. Hyperarterial/venous thrombotic events within 6 months, such as cerebrovascular accident (including transient ischemic attack), deep venous thrombosis and pulmonary embolism;
15. According to the investigator 's judgment, there are concomitant diseases that seriously endanger the safety of patients or affect the completion of the study.
