- Incidence of adverse events (AEs) [ Time Frame: 12 months ]Measured by the number of patients with AEs in Phase 1b portion of the study.
- Anti-tumor activity of AVB-S6-500 in combination with nab-paclitaxel and gemcitabine in Phase 1b portion of the study [ Time Frame: 12 months ]Measured by Objective Response Rate (ORR): Proportion of subjects who have a partial or complete response to therapy relative to baseline in Phase 1b portion of the study.
- Anti-tumor activity of AVB-S6-500 in combination with nab-paclitaxel and gemcitabine in Phase 2 portion of the study [ Time Frame: 30 months ]Measured by progression free survival (PFS) in patients receiving AVB-S6-500, nab-paclitaxel, and gemcitabine versus patients receiving nab-paclitaxel, and gemcitabine alone in Phase 2.
- Pharmacokinetics: AUC [ Time Frame: 30 months ]Area under the AVB-S6-500 concentration-time curve.
- Pharmacokinetics: Cmax [ Time Frame: 30 months ]Maximum observed AVB-S6-500 concentration.
- Pharmacokinetics: Tmax [ Time Frame: 30 months ]Time of maximum observed AVB-S6-500 concentration.
- Pharmacokinetics: t1/2 [ Time Frame: 30 months ]Apparent terminal half-life of AVB-S6-500.
- Pharmacodynamic marker assessment [ Time Frame: 30 months ]Change from the baseline in GAS6 serum levels.
- Anti-drug antibody (ADA) titers [ Time Frame: 30 months ]Change from baseline in ADA titer.
- Disease control rate [ Time Frame: 30 months ]Proportion of subjects who have a complete or partial response to therapy or maintain stable disease.
- Duration of response (DOR) [ Time Frame: 30 months ]Measured from the date of partial or complete response to therapy until the cancer progresses.
- Overall survival [ Time Frame: 60 months ]Time following the treatment until death.
