Design outcomes

Primary

MeasureTime frame
Main Objective: Phase I - To define the maximum tolerated doses of multiple doses of L-DOS47 administered intravenously to patients with non-squamous non-small cell lung cancer when given as monotherapy. Phase II - To make a preliminary assessment of the efficacy of L-DOS47 in patients with non-squamous non-small cell lung cancer.;Secondary Objective: Phase I and Phase II - To evaluate the pharmacokinetics of L-DOS47 in patients with non-squamous non-small cell lung cancer. - To evaluate the immunogenicity of L-DOS47 in patients with non-squamous non-small cell lung cancer - To evaluate the safety and tolerability of multiple doses of L-DOS47 in patients with non-squamous non-small cell lung cancer;Primary end point(s): Phase I - The incidence and severity of drug-related adverse events as per dose-limiting toxicity definition. Phase II - The overall response rate defined as the proportion of patients with a best (confirmed) objective response (RECIST v1.1) of complete response and partial response.;Timepoint(s) of evaluation of this end point: Phase I: = 3 weeks after start of treatment Phase II: End of treatment visit, or previous radiologic exam date if radiologic exam was performed < 6 weeks before the end of treatment visit

Secondary

MeasureTime frame
Secondary end point(s): a. L-DOS47-related toxicity during the first 2 hours after infusion, assessed by: i.Incidence and severity of AEs and SAEs ii.changes in vital signs b. Incidence and severity of AEs and SAEs c. Changes from Baseline in the following additional safety parameters: clinical laboratory assessments, vital signs, weight, oxygen requirement and 12-lead ECG d. Changes in physical examination e. The evaluation of anti-L-DOS47 antibody over time ;Timepoint(s) of evaluation of this end point: a. 2 hours after start of infusion b. 30 days post last dose of study treatment c. D8, Day 15 of Cycle 4 (end of Cycle 4) 7 days after last dose. Early Termination, Cycle 5 and beyond Days 1 & 8 predose d. D8 Day 15 of Cycle 4 (end of Cycle 4) 7 days after last dose. Early Termination, Cycle 5 and beyond Days 1 & 8 predose, 30 days post last dose of study treatment e. 30 days post last dose of study treatment
