Brief summary: This phase II trial studies how well cadonilimab combined with Bevacizumab and docetaxel work in treating patients with non-squamous and stage IV non-small cell lung cancer. Cadonilimab, a PD-1/CTLA-4 bispecific antibody, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab can regulate tumor microenvironment. Docetaxel was used in standard of care chemotherapy for non-small cell lung cancer, work to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving cadonilimab, bevacizumab and docetaxel together may work better in treating patients with non-squamous non-small lung cancer compared to standard of care.


Eligibility criteria: Inclusion Criteria:

1. Age≥18 years old

14. Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) ≤ 2.5 x ULN (≤ 5 x ULN for participants with liver metastases) (collected within 10 days prior to the start of study treatment
15. Serum albumin(ALB)≥28 g/L
16. International standardized ratio (INR) and activated partial thrombin time (APTT) ≤ 1.5 × ULN
17. Left ventricular ejection fraction (LVEF) ≥ 50%
18. A male participant must agree to use a contraception during the treatment period plus an additional 120 days after the last dose of study treatment and refrain from donating sperm during this period
19. A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:

    1. Not a woman of childbearing potential (WOCBP) OR
    2. A WOCBP who agrees to follow the contraceptive guidance during the treatment period and for at least 120 days plus 30 days (a menstruation cycle) after the last dose of study treatment

Exclusion Criteria:

1. Previously received treatment for tumor immune mechanism other than any anti-PD-1/L1 inhibitor for advanced NSCLC stage, such as CTLA-4（CD152）、TIGIT、OX-40、CD137、ICOS、CD40、CD47、CD73、GITR、TOX、LAG-3、TIM3、SIRPα、BTLA（CD272）、VISTA（B7-H5）、LIGHT（CD258）、B7-H3（CD276）、 B7-H4（VTCN1）、HVEM、CD80/CD86、MHC Ⅱ、GAL9、IDO、PVR（CD155）、Nectin-2（CD112）.
2. Patients have prior exposure to docetaxel, bevacizumab
3. The last systemic anti-tumor treatment (chemotherapy, immunotherapy, biological agents, anti-angiogenic drugs, etc.) was received within 3 weeks before the first administration.
4. The following treatments were received within 2 weeks before the first administration: TKI treatment, hormone anti-tumor treatment, palliative local treatment for non-target lesions Non-specific immunomodulatory therapy (such as interleukin, interferon, thymosin, tumor necrosis factor, etc., excluding IL-11 for thrombocytopenia).
5. Patients with explosive progress.
6. Patients with other active malignant tumors except for NSCLC within 3 years before enrollment. Patients with other malignant tumors that have been cured by local treatment, such as basal or cutaneous squamous cell carcinoma, superficial bladder cancer cancer, cervical or breast cancer in situ, are not excluded.
7. Patients with active autoimmune diseases that require systemic treatment in the past two years (such as the use of disease improvement drugs, corticosteroids, immunosuppressants) (excluding irAE caused by the use of PD-1/L1 inhibitors). Replacement therapy (such as thyroid hormone, insulin, or physiological corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered as a systemic treatment.
8. Patients can not swallow pills, with malabsorption syndrome, or any condition that affects gastrointestinal absorption;
9. Patients with active or previous history of inflammatory bowel disease (such as Crohn's disease, ulcerative colitis or chronic diarrhea).
10. Patients have a history of immune deficiency, with HIV antibody test positive or use systemic corticosteroids or other immunosuppressants for a long time.
