Human ADME Study of [14C]-AZD1390

A Phase I, Open-label Study to Assess the Absorption, Distribution, Metabolism, and Excretion (ADME) of AZD1390 After a Single Oral Dose of [14C]-AZD1390 in Participants With Advanced Solid Malignancies

This is a Phase I, multicentre, single-dose, open-label study to assess the absorption, distribution, metabolism, and excretion of [14C]-AZD1390.

On Day 1, participants will receive one dose of [14C]-AZD1390 . Participants will be confined to the study site until Day 8.

Approximately 8 enrolled male and female participants will receive study intervention in order to achieve a minimum of 4 evaluable participants.

Participants in this study will contribute to essential knowledge that will support the development of AZD1390 as a potential treatment for GBM, a malignancy of high unmet need, while being exposed to a low level of immediate risk.
