Study Arms (2)
IBI363
EXPERIMENTALIBI363 is a first-in-class bispecific monoclonal antibody (mAb) comprised of an interleukin-2 (IL-2) mutein fused with a recombinant anti-programmed cell death protein 1 (anti-PD-1) mAb. IBI363 was precisely designed and constructed to afford targeted binding of tumor-specific CD8+ T cells (TSTs) that co-express PD-1 and CD25 (IL2Ra) receptors. The mechanism of action of IBI363 is blocking the PD-(L)1 and activating the IL-2 pathways simultaneously to reverse T cell exhaustion and promote activation of T cells and natural killer (NK) cells, and consequently eliminate tumor cells.

Eligibility Criteria
You may qualify if:
- Willing to sign the written informed consent form and be able to comply with the visit schedule and related procedures specified in the protocol.
- Male or female participants must be at least 18 years old or the legal age of majority in their country, whichever is greater.
- Have locally unresectable advanced or metastatic histologically or cytologically confirmed squamous NSCLC Note: Mixed small cell carcinoma, or other pathological components are excluded.
- Resistant or refractory to systemic anti-tumor therapy, including platinum-based doublet chemotherapy and primary or secondary resistance to anti-PD-1/PD-L1 monoclonal antibody given in combination or sequentially; or given as neoadjuvant and/or adjuvant therapy, which will be considered first-line treatment if the disease has recurred or progressed during such treatment or within 6 months after discontinuation.
- Radiographic progression per RECIST v1.1 during or within 6 months after discontinuation of anti-PD-1/PD-L1 monoclonal antibody treatment.
- Agree to provide archival (collected within 2 years before signing the informed consent form if biopsy cannot be performed or participant refuses fresh biopsy) tumor tissue specimens for PD-L1 expression level testing and exploratory analysis of other biomarkers.
- Have at least one measurable lesion (target lesion) by computed tomography (CT) or magnetic resonance imaging (MRI) according to RECIST v1.1. Lesions that have previously received radiotherapy or intratumoral injection can be used as measurable lesions if they show progression after treatment (either tissue confirmed or more than 3 months after treatment) as per RECIST v1.1.
- ECOG PS score of 0 or 1.
- Expected survival time ≥ 3 months.
- Women of childbearing potential (WOCBP) or men with female partners of childbearing potential must agree to take effective contraceptive measures during the entire course of treatment and for 6 months after the last dose of study treatment.
- Lactating women must agree to strictly abstain from breastfeeding during the entire Treatment Period and for 6 months after the treatment.
You may not qualify if:
- Women who are pregnant or lactating, or intending to become pregnant before, during, or within 6 months after the last dose of any study drug. WOCBP or fertile men with WOCBP partner(s), not using and/or not willing to use a highly effective method of contraception.
- Known actionable genomic alteration, including any of the following driver gene mutations:
- Epidermal growth factor receptor (EGFR): including exon 19 deletion, exon 21 L858R, exon 20 T790M, exon 20 S768I, exon 21 L861Q, exon 18 G719X, and exon 20 insertion mutations.
- Kirsten rate sarcoma virus (KRAS) G12C mutation.
- Anaplastic lymphoma kinase (ALK) rearrangement.
- ROS proto-oncogene 1, receptor tyrosine kinase (ROS1) rearrangement.
- B-Raf proto-oncogene, serine/threonine kinase (BRAF) V600E mutation.
- Neurotrophic tyrosine receptor kinase (NTRK) 1/2/3 fusion.
- MET proto-oncogene, receptor tyrosine kinase (MET) exon 14 skipping mutation.
- RET proto-oncogene (RET) rearrangement.
- V-erb-b2 avian erythroblastic leukemia viral oncogene homolog 2 (ERBB2, also known as HER2) mutation.
- Other gene mutation types where a targeted therapy has been completely approved for marketing by a local regulatory authority.
- Note: It is not mandatory to have undergone driver gene testing.
- Active or symptomatic brain metastases. Participants who are clinically and radiologically stable at least 4 weeks after treatment and participants with small, asymptomatic, incidental, untreated brain metastases that remain stable ≥ 4 weeks may participate in this study as long as they meet all of the following criteria:
- No metastases to meninges, midbrain, pons, medulla oblongata, spinal cord or cerebellar metastases.
