Brief summary: This is a prospective, single-arm, multi-center, phase Ⅱ trial to evaluate the efficacy and safety of Polymeric Micelles paclitaxel(pm-Pac), platinum (cisplatin/carboplatin) in combination with Ivonescimab as first-line treatment in metastatic squamous NSCLC patients.


Eligibility criteria: Inclusion Criteria:

1. Written informed consent must be signed before implementing any trial-related procedures;
2. Age ≥18 years old;
3. Patients with histologically or cytologically confirmed metastatic or recurrent (stage IV) squamous NSCLC (International Association for the Study of Lung Cancer and American Joint Committee on Classification of Cancer, 8th Edition TNM staging), inoperable or inappropriate for radical concurrent chemoradiotherapy, and without previous systemic treatment；. Patients with mixed histology (example adenosquamous) are allowed if there is squamous component in the specimen. PD-L1 immunohistochemical results is required before enrollment.

5.According to the Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1), there is at least one measurable lesion.

6.Have not received any previous systemic antitumor therapy for advanced/metastatic diseases. Participants who have previously received platinum-based adjuvant/neoadjuvant chemotherapy, or radical chemoradiotherapy for advanced disease are allowed to enroll if the interval between disease progression or recurrence and the end of the last chemotherapy treatment is at least 6 months.

7.ECOG score: 0-1 8.Expected survival time \> 3 months 9.Normal organ function, patients should meet the following laboratory indicators:

1. Blood routine test should meet the following criteria (no blood transfusion, no use of blood products, granulocyte colony-stimulating factor, or other hematopoietic growth factors within 7 days before blood routine test); White blood cell count ≥3.0x10\^9/L, absolute neutrophil count (ANC) ≥1.5x10\^9/L，Platelet count ≥100×10\^9/L Hemoglobin \>9g/dL. If patients receive blood component transfusion (red blood cells, platelets, etc.) during the screening period, blood routine test should be performed again at an interval of 1 week to meet the above criteria before continuing screening.
2. Blood biochemical examination must meet the following criteria: Total bilirubin ≤1.5 times the upper limit of normal (ULN), and aspartate aminotransferase (AST), alanine aminotransferase (ALT), or alkaline phosphatase (ALP) ≤2.5 times ULN (ALT, AST, or ALP≤ 5×ULN for patients with liver metastases, and ALP≤10×ULN for patients with bone metastases); Serum creatinine ≤1.5 times ULN and creatinine clearance (calculated using Cockcroft-Gault formula) ≥60 ml/min；
3. Normal coagulation function, defined as international normalized ratio (INR) or prothrombin time (PT) ≤1.5 times ULN;
4. Normal thyroid function, defined as thyroid stimulating hormone (TSH) within the normal range. Subjects with baseline TSH beyond the normal range, but total T3 (or FT3) and FT4 are within the normal range can also be enrolled;
5. Myocardial zymogram within the normal range (if the investor judges that the simple laboratory result is not of clinical significance, the patient is allowed to be included); 10.For female patients of childbearing age, a negative urine or serum pregnancy test should be performed within 3 days before the first study drug administration (day 1 of cycle 1). If the urine pregnancy test result cannot be confirmed as negative, a blood pregnancy test is requested. Female patients who are not of childbearing age are defined as those who have been postmenopausal for at least 1 year or have undergone surgical sterilization or hysterectomy; 11.If there is a risk of conception, all patients (male or female) are required to use contraception throughout the treatment period until 180 days after the last study drug administration.

Exclusion Criteria:

1. Currently participating in interventional clinical research treatment;
2. Has non-squamous histology NSCLC. Mixed tumors will be categorized by the predominant cell type; if small cell elements are present, the subject is ineligible; for non-small cell histology if there is any squamous element is present (example adenosquamous), the subject is eligible; the squamous element does not have to be predominant.
3. Previously received immunotherapy, including immune checkpoint inhibitors (such as anti-PD-1 /L1 antibodies, anti-CTLA-4 antibodies, anti-LAG-3 antibodies, etc.), immune checkpoint agonists (such as: Subjects of ICOS, CD40, CD137, GITR, OX40 antibody, etc.), immune cell therapy, etc., any treatment targeting the immune mechanism of tumor action;

Central, squamous non-small cell lung cancer with cavities and a higher risk of bleeding as determined by the investigators; Received continuous antiplatelet or anticoagulant therapy within 10 days prior to initial administration;
6. Tumor invasion of surrounding important organs and blood vessels (such as aorta, heart and pericardium, superior vena cava, trachea, esophagus, etc.) or esophagotracheal fistula or esophagopleural fistula risk;
7. Subjects with uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage (subjects who do not require drainage effusion or whose frequency of drainage is less than once per month can be enrolled);

A history of deep vein thrombosis, pulmonary embolism, or any other severe thromboembolism within the 3 months prior to enrollment (implantable intravenous port or catheter-derived thrombosis, or superficial venous thrombosis was not considered "severe" thromboembolism);

Active systemic infections, including tuberculosis (clinical diagnosis including clinical history, physical examination and imaging findings, and TB testing based on local medical practice), hepatitis B (known to be positive for HBV surface antigen (HBsAg), HBV DNA ≥1000cps/ml or the lower limit of its reference value), hepatitis C or human immunodeficiency virus (HIV antibody positive);
13. A known mental illness or substance abuse condition that may affect compliance with the test requirements;
14. There is a medical history, disease, treatment, or abnormal laboratory result that could interfere with the test results or prevent the subject from fully participating in the study, or the investigator believes that participation in the study is not in the subject's best interest.
