DS-8201a | Part 1 Dose escalation |
This is an open-label, two-part, multiple study to evaluate the safety and tolerability of DS-8201a in patients with advanced solid malignant tumors.
This study is one single group of participants in two periods. It is therefore not randomized. The dosage strength will change during the study but all participants will receive the same study drug DS-8201a. So the study is not a true 2 arm study, it is a 2 part study.
Name | Type | Description | Interventions |
---|---|---|---|
Part 1 Dose escalation | Experimental | Part 1 is a dose escalation to identify the Maximum Tolerated dose (MTD) or the recommended phase 2 dose of DS-8201a guided by the modified continuous reassessment method using a Baysian logistic regression model following escalation with overdose control principal. |
|
Part 2 Dose expansion | Experimental | Part 2 is a dose expansion to examine the safety and efficacy of DS-8201a and it is consist of multiple cohorts: in subjects with trastuzumab emtansine (T-DM1)-treated HER2 overexpressing breast cancer (Part 2a); trastuzumab-treated HER2 overexpressing gastric or gastroesophageal junction adenocarcinoma (Part 2b); HER2 low expressing breast cancer (Part 2c), and HER2 expressing other solid malignant tumor (Part 2d) |
