A Phase 0 Multicenter Study of the Pharmacodynamic Effects of Intratumoral Microdose Administration of Rilvegostomig, Volrustomig, Sabestomig, and AZD9592
Presage Biosciences
Summary
This is a multi-center, open-label, Phase 0 substudy designed to evaluate the localized pharmacodynamics (PD) of rilvegostomig, volrustomig, sabestomig, and AZD9592 within the tumor microenvironment (TME) when administered intratumorally in microdose quantities via the CIVO device in patients presenting with Head and Neck Squamous Cell Carcinoma (HNSCC) with a surface accessible lesion, who are scheduled for tumor and/or regional node dissection as part of their standard treatment. PD effects due to injected investigational agents, either as single agents or as AZD9592 drug combinations with the evaluated biologics, will be compared to those elicited by pembrolizumab alone, which will also be injected in microdose quantities via the CIVO device.
Description
The CIVO Microdose Injection Device (MID) simultaneously delivers multiple drugs and drug combinations (Up to 8), each in microdose amounts, into a single patient tumor and enables comparisons of the resulting biomarker responses that occurred while that tumor was still in the native microenvironment. AstraZeneca is developing three novel assets: rilvegostomig, volrustomig, and sabestomig, all of which are bispecific monoclonal antibodies designed to stimulate antitumor immunity. In this Phase 0 clinical trial, the PD effects of these investigational assets in the TME of patients presenting wi…
