Treatment groups
Trial outcomes
Primary outcomes
Objective Response Rate (ORR)
The sum of the number of cases with Complete Response (CR) and Partial Response (PR) in all treated tumor patients (CR + PR) divided by the total number of cases.
Secondary outcomes
Duration of Response (DOR)
Time from the start of the first assessment of CR or PR in tumor patients to PD or death due to any reason.
Progression Free Survival (PFS)
Time from start of treatment to progression of disease (PD) or death, whichever occurs first, in patients with tumors.
Overall Survival (OS)
Time from start of treatment to death due to any reason.
Safety and tolerability assessed by adverse events (AEs)
An AE is any untoward medical occurrence in a subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
