Overview
The study is a prospective multi-cohort clinical study. Cohort A is evaluating the efficacy and safety of IBI318 in combined with lenvatinib in advanced NSCLC patients who had failed first-line PD-1/PD-L1 inhibitor therapy. Cohort B is the efficacy and safety of advanced NSCLC with EGFR-sensitive mutation /ALK fusion after EGFR-TKI /ALK-TKI treatment resistance. Cohort C is the efficacy and safety of first-line treatment of advanced NSCLC with negative PD-L1 expression and EGFR, ALK, and ROS1 wild-type. After being screened to meet the inclusion criteria, they will receive IBI318 combined with lenvatinib until the disease progresses, death, toxicity is intolerable, informed consent is withdrawn, new anti-tumor therapy is started, or the treatment is terminated for other reasons specified in the plan.
Description
The study is a prospective multi-cohort clinical study. Cohort A is evaluating the efficacy and safety of IBI318 in combined with lenvatinib in advanced NSCLC patients who had failed first-line PD-1/PD-L1 inhibitor therapy. Cohort B is the efficacy and safety of advanced NSCLC with EGFR-sensitive mutation /ALK fusion after EGFR-TKI /ALK-TKI treatment resistance. Cohort C is the efficacy and safety of first-line treatment of advanced NSCLC with negative PD-L1 expression and EGFR, ALK, and ROS1 wild-type.
After being screened to meet the inclusion criteria, they will receive IBI318 combined with lenvatinib until the disease progresses, death, toxicity is intolerable, informed consent is withdrawn, new anti-tumor therapy is started, or the treatment is terminated for other reasons specified in the plan. During the treatment, RECIST v1.1 was used for clinical tumor imaging evaluation, once every 6 weeks; after 24 weeks of medication, evaluation can be done every 8 weeks.
Subjects receiving IBI318 combined with lenvatinib have the first evidence of imaging PD according to RECIST v1.1. If the subject is clinically stable, there is no evidence of rapid imaging progress, and the investigator assesses that it can continue from the study If the patient is benefited from the drug, the subject can continue the current study treatment, and the imaging evaluation must be repeated at least 6 weeks (± 7 days) later for confirmation. If PD is confirmed by re-assessment, the subject should stop the study treatment; if PD is not confirmed, the study treatment will continue, and the assessment will be carried out at the time point of the imaging examination plan specified in the plan until the PD is confirmed by imaging.

- Cohort A: histological or cytological confirmed locally advanced (IIIB-IIIC) or metastatic (stage IV) NSCLC (International Association for the Study of Lung Cancer and Joint Committee on the American Classification of Cancer, TNM Lung cancer stage 8) without EGFR gene sensitive mutations, ALK gene fusion or ROS1 gene fusion confirmed by histological specimens, Relapse after failure of first-line anti-PD-1 /PD-L1 antibody therapy, as follows:
- Only one anti-PD-1/PD-L1 antibody monotherapy or combination therapy is accepted in the advanced stage of the disease, and other immunotherapy is not allowed;
- Previous anti-PD-1/L1 antibody monotherapy or combination therapy has the best curative effect (according to RECIST 1.1 criteria) as partial remission, complete remission, or stable disease for ≥6 months (defined as within 6 months from the first medication) No disease progression has occurred);
- Disease progression confirmed by imaging studies occurred during or after the most recent treatment.
Cohort B: histological or cytological confirmed locally advanced (IIIB-IIIC) or metastatic

histologically confirmed EGFR-sensitive mutations or ALK fusion, Relapse after failure of
anti-EGFR-TKI or ALK-TKI therapy, as follows:
In patients with EGFR-tKI sensitive mutations, the specific history of previous EGFR-TKI
treatment can be one of the following:
1. There is no T790M mutation in 20 exon after the failure of previous one or two
generations of EGFR-TKI (including gefitinib, erlotinib, icotinib and afatinib);
2. The 20 exon T790M mutation occurred after the treatment failure of the first or second
generation EGFR-TKI monotherapy (including gefitinib, erlotinib, icotinib, and
afatinib, etc.), and disease progression recurred after treatment with osimertinib or
other third generation EGFR-TKI;
3. Failure of prior osimertinib or other third-generation EGFR-TKI therapy as first-line
therapy (regardless of EGFR T790M mutation status);
4. Those who are allowed to receive neoadjuvant/adjuvant targeted therapy in the early
stage and develop drug resistance after subsequent adjuvant targeted therapy, and
their drug resistance status meets one of the three requirements of appeal.
For patients with ALK fusion NSCLC, disease progression should occur after adequate
ALK-TKI treatment, and there is no opportunity for subsequent targeted therapy.
Cohort C: Locally advanced NSCLC that is not suitable for radical surgery or
radiotherapy, or that has relapsed without systematic treatment, or that has

Patients who have previously received neoadjuvant or adjuvant therapy can also receive
neoadjuvant or adjuvant therapy (but neoadjuvant or adjuvant therapy is
chemotherapy/radiotherapy, not immunotherapy), and the end of neoadjuvant/adjuvant
therapy should be ≥6 months after tumor progression; If the pathological type is
adenocarcinoma, the absence of EGFR-sensitive mutations or ALK fusion or ROS1 fusion
should be confirmed. Negative expression of PD-L1 was defined as TPS <1% using 22C3
test.
