This clinical trial will evaluate DS-6000a in participants with advanced renal cell carcinoma (RCC) and ovarian cancer (OVC). The main goals of this study will be to investigate the recommended dose of DS-6000a that can be given safely to participants, assess the side effects of DS-6000a, and evaluate the effectiveness of DS-6000a.

Detailed Description

DS-6000a is an antibody drug conjugate that specifically binds to CDH6 on the cell surface of target cells, which leads to the internalization of DS-6000a into the cells. MAAA-1181a that is released from DS-6000a in the target cells inhibits cell replication and induces cell apoptosis. This study will evaluate DS-6000a given as a single agent once every 21 days. The dose escalation phase will enroll participants with OVC and RCC, and is designed to assess the safety and tolerability of DS-6000a and to determine the maximum tolerated dose (MTD)/recommended dose for expansion (RDE). Following the selection of the RDE, the dose expansion phase will be initiated to evaluate clinical activity of DS-6000a.


Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
