Absolute Values in Ataxia-Telangiectasia Mutated (ATM) Pathway Readouts Assessed by Flow Cytometry and Immunohistochemistry: Gamma-H2AX Secondary · Baseline up to Day 23

gamma-H2AX is measured by flow cytometry and immunohistochemistry. Absolute values were reported for each participant as descriptive data for this outcome measure was not calculated. P= Part, D=Day, H=Hour in the below mentioned categories. Mean Fluorescent Intensity (MFI) is a number generated by the flow cytometer; an instrument that measures the fluorescent signal emitted by a sample. The stronger the fluorescent signal, the higher the MFI value detected by the instrument's acquisition software. The values displayed in the system represent each MFI measurement at different time points, with

Sponsor's own description

The purpose of this study was to determine the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), maximum tolerated dose (MTD) (if reached) and early signs of efficacy of M4076 monotherapy in participants with solid tumors in dose escalation (Part 1A). Once the recommended dose for expansion (RDE) was declared in Part 1A, a preliminary food effect cohort, Part 1B, will follow at the RDE determined from Part 1A.
