- Number of patients with treatment related adverse events as assessed by NCI CTCAE v.5.0 [ Time Frame: From time of first dose to 3 months after surgery ]To evaluate the tolerability, incidence and severity of AEs and SAEs graded according to NCI CTCAE v5.0 of FL-101 as monotherapy and in combination with nivolumab.
- Number of patients with treatment efficacy as assessed by pathological response (percentage of residual tumor) by independent pathology review. [ Time Frame: At time of surgery (around 6-8 weeks) ]
Cohort 1: To evaluate the activity of FL-101 neoadjuvant monotherapy in patients with Stage IA3 or IB NSCLC
Cohort 2: To evaluate the effect of FL-101 in combination with nivolumab compared to nivolumab plus placebo in neoadjuvant therapy in patients with Stage II-IIIA NSCLC
- Major Pathologic Response [ Time Frame: At time of surgery (around 6-8 weeks after first dose) ]To determine major pathologic response (MPR), defined as ≤10 percent viable tumor
- Complete Pathologic Response [ Time Frame: At time of surgery (around 6-8 weeks after first dose) ]To estimate complete pathologic response (CPR), defined as the absence of residual invasive cancer in resected lung specimens and lymph nodes
- Objective Response Rate (ORR) [ Time Frame: At time of surgery (around 6-8 weeks after first dose) ]To estimate objective response rate (ORR) by RECIST 1.1
- MRD measurement by ctDNA [ Time Frame: From time of first dose to 3 months after surgery ]To describe the time course of minimal residual disease (MRD) response by ctDNA and recurrence in correlation with clinical response
- Plasma Concentration of FL-101 [ Time Frame: From time of first dose up to 3 months after surgery ]To evaluate the pharmacokinetics of FL-101 in patients with NSCLC
- Plasma IL-1β/IL-6 levels [ Time Frame: From time of first dose up to 3 months after surgery ]To evaluate the effect of FL-101 on pharmacodynamic biomarkers
- Serum hsCRP [ Time Frame: From enrollment up to 3 months after surgery ]To evaluate the effect of FL-101 on pharmacodynamic biomarkers
- Prevalence and incidence of Anti-FL-101 antibodies [ Time Frame: From time of first dose up to 3 months after surgery ]To evaluate possible immunogenicity of FL-101
