About
Primary objective：
·To assess the antitumor activity of tusamitamab ravtansine in combination with sintilimab and tusamitamab ravtansine in combination with sintilimab, platinum-based chemotherapy and pemetrexed in the NSQ NSCLC population.
Secondary objectives： To assess the safety and tolerability of tusamitamab ravtansine in combination with sintilimab and tusamitamab ravtansine in combination with sintilimab, platinum-based chemotherapy and pemetrexed in the NSQ NSCLC population.
To assess the pharmacokinetic (PK) characteristic of tusamitamab ravtansine in combination with sintilimab and tusamitamab ravtansine in combination with sintilimab, platinum-based chemotherapy and pemetrexed in the NSQ NSCLC population.
Full description
The expected duration of the study intervention for participants may vary based on progression date; median expected duration of study per participant is estimated 10 months (up to 1 month for screening, a median of 6 months for treatment, and a median of 3 months for end-of-treatment assessments and safety follow-up visit).

Inclusion and exclusion criteria
Inclusion criteria apply:
I1. Age ≥ 18 years and < 75 years males of females.
I2. Histologically- or cytologically-confirmed diagnosis of advanced or metastatic NSQ NSCLC with no EGFR sensitizing mutation, BRAF mutation or ALK/ROS alterations.
I3. No prior systemic therapy for the treatment of advanced or metastatic disease.
I4. Expression of CEACAM5 as demonstrated prospectively by a centrally assessed IHC assay with ≥ 2+ in intensity involving at least 1% of the tumor cell population in archival tumor sample (or if not, available fresh biopsy sample will be collected if considered an acceptable risk by the treating physician).
I5. Adequate hematologic/liver/renal/coagulation function.
I6. Life expectancy exceeds 3 months.
I7. Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.
Exclusion criteria:
E1. Hstologically or cytologically confirmed mixed NSCLC with small-cell or prodominant squamous carcinoma components.
E2. Unstable brain metastases and history of leptomeningeal disease.
E3. Significant concomitant illness, including any severe medical conditions that, in the opinion of the investigator or sponsor, would impair the subject's participation in the study or interpretation of the results.
E4. History within the last 3 years of an invasive malignancy other than the one treated in this study, with the exception of resected/ablated basal or squamous-cell carcinoma of the skin or carcinoma in situ of the cervix, or other local tumors considered cured by local treatment.
E5. History of known acquired immunodeficiency syndrome (AIDS) related illnesses or known HIV disease requiring antiretroviral treatment, or active hepatitis A, B (defined as either positive HBsAg or positive hepatitis B viral DNA test above the lower limit of detection of the assay), or C (defined as a known positive hepatitis C antibody result and known quantitative HCV RNA results greater than the lower limits of detection of the assay) infection.
E6. History of active autoimmune disease that has required systemic treatment in the past 2 years.
E7. Non-resolution of any prior treatment-related toxicity to < Grade 2 according to NCI CTCAE V5.0, with the exception of alopecia, vitiligo, or active thyroiditis controlled with hormone-replacement therapy.
E8. Unresolved corneal disorder or any previous corneal disorder considered by an ophthalmologist to predict higher risk of drug-induced keratopathy. The use of contact lenses is not permitted. Patients using contact lenses who are not willing to stop wearing them for the duration of the study intervention are excluded.
E9. Received traditional Chinese medicine with anti-tumor indications within 2 weeks prior the first administration, or received immunomodulatory drugs (including thymosin, interferon, interleukin, except for local use for pleural effusion control) within 2 weeks prior administration.
E10. Have received prior systemic therapy for advanced/metastatic NSCLC.
