Official title
Phase 1/2A Study of OTP-01, a Dual Paratopic PD-1/VEGFR2 Antibody, in Patients With Advanced Solid Tumors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The main goals of this clinical trial are to find out what the best dose of the study drug, OTP-01, is for patients with solid tumors through understanding how it is tolerated and any side effects that it may cause. The trial will also see if OTP-01 causes tumors to shrink and how the body processes OTP-01 by measuring drug levels in the blood. The main questions this study aims to answer are: * What is the recommended dose of OTP-01 for adults with solid tumors? * Is OTP-01 safe and tolerable? * Does OTP-01 reduce tumor growth? Participants will: * Receive OTP-01 through an infusion into a vein. Doses will be spaced out and never more than once a week. * Have blood tests to evaluate safety and drug levels of OTP-01. These will be done often at first and then less frequently as treatment continues. * Have radiographic scans of their tumor at baseline and during the study at regular intervals. * Have the choice to have an optional tumor biopsy before and after treatment to help researchers understand how OTP-01 affects cancer and the immune system. These biopsies are voluntary and will not affect participation in the study.
