Phase I clinical development

Transitioning to First-in-Human

We bridge the gap between discovery and first-in-human, ensuring your process, material, and data are ready for GMP execution.

Phase I Clinical Development
Quick filter:

Transitioning from discovery to first-in-human requires the integration of chemistry, engineering, analytical, and solid-state expertise into a manufacturable reality.

Many programs stall at this point. Routes that worked in the lab fail at scale, impurities emerge unexpectedly, or material supply cannot meet GMP standards.

We help you cross that boundary. We develop safe, efficient, and sustainable processes, ensuring your compound is ready for GMP manufacture, analytical qualification, and regulatory submission. We bridge the gap between discovery and clinical readiness, helping you choose the right GMP partner and building the scientific and technical foundation to support every subsequent phase.

How We Support You
Defining a Scalable Route
We identify and optimise synthetic routes through rapid feasibility studies, route scouting, and design of experiments (DoE).
Developing and Optimising the Process
Establish robust, sustainable, and safe operating conditions through process development, thermal hazard assessment, and model-led design.
Preparing for First GMP Manufacture
Deliver non-GMP material and GMP analytical development to ensure full technology and knowledge transfer to your manufacturing site.
Characterising and Controling Your Product
Develop analytical methods, perform impurity profiling, and design control strategies aligned with ICH guidance.
Mitigating Risk and Accelerating Readiness
Provide documentation, risk assessments, and technical justification to support regulatory submissions and early-stage manufacturing reviews.
