Lab values

• Subjects with grade II or above myocardial ischemia or myocardial infarction and poorly controlled arrhythmias (QTc interval \> 450 ms for males and QTc interval \> 470 ms for females). Subjects with grade III-IV cardiac insufficiency or with left ventricular ejection fraction (LVEF) less than 50% according to NYHA criteria;
• Has known allergy to Camrelizumab, or pemetrexed, or paclitaxel, or albumin paclitaxel, or carboplatin, or cisplatin or any of accessories;

Other

• Women who are pregnant or lactating；

• Histological or cytological diagnosis of non-small cell lung cancer（NSCLC）;
• MRI confirmed brain parenchyma metastasis, ≥ 3 brain lesions, or 1-2 brain lesions but not suitable for local treatment or refused local treatment. At least one brain measurable lesion ≥ 5mm . Included with or without neurological symptoms;
• Has not received prior systemic treatment for metastatic NSCLC. Subjects who have received prior neo-adjuvant, adjuvant chemotherapy, or chemoradiotherapy with curative intent must have experienced interval of at least 12 months from diagnosed of advanced or metastatic disease since the end of surgery;
• Has confirmation that epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK)-directed therapy is not indicated;
• Has a performance status of 0 or 1 on the Eastern Cooperative Oncology Group (ECOG) Performance Status;
• Has adequate organ function;
• Women of childbearing age must undergo a serological pregnancy test within 7 days before the first dose with negative results. Subjects willing to use an effective contraceptive method during the study and within 90 days after the last dose of study medication;
