Первичные конечные точки

• Safety- Part 1A & Part 2A (dose escalation) and Part 2B (dose expansion) [Срок оценки: Measured from the informed consent until Day 90 post-last dose.]
• Efficacy- Part 2B only (dose expansion) [Срок оценки: Measured every 6 weeks for 48 weeks and every 12 weeks thereafter from first dose until disease progression or death in the absence of disease progression(approximately 2 years)]

• PK Time to maximum plasma concentration (tmax)- Part 1A and Part 2A (dose escalation) and Part 2B (dose expansion) [Срок оценки: Measured from pre-infusion on Cycle 1 up to Day 28 post last dose on predefined intervals]
• PK Clearance- Part 1A and Part 2A (dose escalation) and Part 2B (dose expansion) [Срок оценки: Measured from pre-infusion on Cycle 1 up to Day 28 post last dose on predefined intervals]
• PK Half-life- Part 1A and Part 2A (dose escalation) and Part 2B (dose expansion) [Срок оценки: Measured from pre-infusion on Cycle 1 up to Day 28 post last dose on predefined intervals]
• PK Minimum observed concentration (Cmin)- Part 1A and Part 2A (dose escalation) and Part 2B (dose expansion) [Срок оценки: Measured from pre-infusion on Cycle 1 up to Day 28 post last dose on predefined intervals]
