|---|---|---|---|---|
| Primary | Assessment of the antitumor activity of berzosertib combined with gemcitabine | Antitumor activity will be assessed in terms of 6-month progression-free rate and is defined as the rate of complete or partial response (CR, PR) or stable disease (SD), as per RECIST v1.1. | 6 months | |
| Primary | Assessment of the antitumor activity of gemcitabine | Antitumor activity will be assessed in terms of 6-month progression-free rate and is defined as the rate of complete or partial response (CR, PR) or stable disease (SD), as per RECIST v1.1. | 6 months | |
| Secondary | 6-month objective response rate (ORR) for patients treated by berzosertib in association with gemcitabine | Objective response is defined as complete response (CR) or partial response (PR) as per adapted RECIST v1.1. | 6 months | |
| Secondary | 6-month objective response rate (ORR) for patients treated by gemcitabine alone | Objective response is defined as complete response (CR) or partial response (PR) as per adapted RECIST v1.1. | 6 months | |
| Secondary | Best overall response for patients treated by berzosertib in association with gemcitabine | Best overall response is defined as the best reponse across all time points (RECIST v1.1). The best overall response rate is determined once all the data for the patient is known | throughout the treatment period, an expected average of 6 months | |

The best overall response rate is determined once all the data for the patient is known | throughout the treatment period, an expected average of 6 months | |
