Brief summary: This is an open-label, single-arm, multi-center, phase II exploratory study that evaluates the efficacy and safety of Toripalimab injection (JS001) combined with Pemetrexed and Anlotinib as a second-line treatment for patients with T790M positive Non-Small Cell Lung Cancer (IIIb / IV ) after Osimertinib resistance.

3. At least one measurable lesion (according to RECIST 1.1); Note: Lesions that have previously received radiotherapy cannot be regarded as target lesions, unless the lesions clearly progress after radiotherapy;
4. Agree to provide formalin-fixed tumor specimens or biopsy specimens after the subject is diagnosed with metastatic cancer, at least 15 sections; if the recent biopsy is not feasible, allow to receive biopsy specimens before adjuvant/neo-adjuvant chemotherapy (archived specimens);
5. ECOG PS 0-2

7. The laboratory examination results within 7 days before enrollment must meet the following standards:

   1. Neutrophils ≥1.5 × 109 / L;
   2. Platelets ≥100 × 109 / L;

   6. AST and ALT ≤ 2.5 × ULN; in patients with liver metastases, ALT and AST ≤ 5 × ULN;
   7. International Normalized Ratio (INR) or Prothrombin Time (PT) ≤ 1.5 × ULN unless the subject is receiving anticoagulant therapy; Activated partial thrombin time (aPTT) or partial thrombin time (PTT) ≤ 1.5 × ULN unless the subject is receiving anticoagulant therapy.
8. Women of childbearing age must confirm that the serum pregnancy test is negative and agree to use effective contraception during drug use and within 60 days after the last dose. Women of childbearing age are defined as sexually mature women in this program: 1) not undergoing hysterectomy or bilateral ovariectomy, 2) natural menopause has not continued for 12 months (amenorrhea after cancer treatment does not exclude fertility).

Exclusion Criteria:

2. Received systemic chemotherapy for advanced NSCLC within 4 weeks before enrollment;
3. Have received EGFR-TKI treatment within 2 weeks before enrollment;
4. Received radiotherapy within 4 weeks or radiopharmaceutical treatment within 8 weeks before enrollment, except for local palliative radiotherapy for bone metastases;
5. Uncontrollable or symptomatic hypercalcemia (\> 1.5mmol / L ionized calcium or calcium\> 12 mg / dL or corrected serum calcium\> ULN);
6. Have undergone major surgery or have not completely recovered from the previous operation within 4 weeks before enrollment ;
7. The toxicity of previous antitumor treatment has not recovered to CTCAE 0-1, except for hair loss；
8. Active or untreated CNS metastases detected by CT or MRI before screening and imaging evaluation: If a new asymptomatic CNS metastases is detected during the screening period , it must undergo radiation therapy and / or surgery . After treatment, if met all other criteria, no additional brain scan is required . Patients who have previously received brain or meningeal metastasis treatment and maintained clinical stability for at least 2 weeks, stopped systemic hormonal therapy (\> 10 mg / day of prednisone or other equivalent hormones) for more than 2 weeks can be included;
9. Spinal cord compression that has not undergone radical surgery and / or radiation therapy, or previously diagnosed spinal cord compression with no clinical evidence showing that the disease is stable for ≥ 4 weeks before enrollment
