Your Early Phase Trial. Our Expertise. Built for US Sponsors.

CHDR is an independent Phase 1 CRO with 40 years of first-in-human expertise, offering US pharma and biotech sponsors a streamlined path to first-in-human studies in Europe, with no IND filing required. We deliver the pharmacodynamic evidence that drives confident go/no-go decisions, with regulatory-ready data packages aligned to both FDA and EMA standards.

  • Proven Phase 1 science, available to US programs: full-service execution from study design through final CSR

  • In-house developed biomarker platforms: NeuroCart®, PainCart®, and DermaToolbox enable sensitive, translational proof-of-pharmacology not available at generalist CROs

  • FDA and EMA-aligned data packages: built to support your US regulatory submissions from day one

  • One integrated team, no handoffs: clinical scientists, PK/PD, bioanalysis, and data management under one roof
