E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to evaluate efficacy, as measured by overall survival (OS), of gemcitabine in combination with TH-302 compared to gemcitabine in
combination with placebo in subjects with previously untreated locally advanced unresectable or metastatic pancreatic adenocarcinoma. |
|
E.2.2 | Secondary objectives of the trial |
To assess efficacy with resepct to:
progression free survival (PFS), and
objective response (OR) and disease control.
To assess patient reported outcomes (PROs) with respect to quality of life (QoL) measured with EORTC QLQ-C30 (Version 3) and EQ-5D-5L, and pain measured by a Numerical Rating Scale (NRS).
To investigate levels of carbohydrate antigen 19-9 (CA19-9),
To assess the safety and tolerability of gemcitabine in combination with TH-302 compared with gemcitabine in combination with placebo. |
