## TL;DR

Imaging core lab and RTSM provider (formerly Parexel Informatics), a leading vendor of blinded central review in oncology trials.

## Summary

Calyx, based in Nottingham and formerly Parexel Informatics, is an imaging core laboratory and randomisation and trial supply provider, and a leading vendor of blinded independent central review in oncology trials. It performs independent review under RECIST and other response criteria and runs randomisation and trial supply systems. OnCo links it to imaging core labs and central review. Whether blinded central review remains the regulatory expectation as AI-assisted response assessment develops is the open question for its core business. The imaging core lab technology page carries the wider picture.
