API Development
and Manufacturing

At Sterling we provide comprehensive services throughout the lifecycle of your molecule, from route scouting and design to process optimisation and clinical supply to commercial cGMP manufacturing.

ADC Development
and Manufacturing

Drawing upon years of experience working with ADCs from their earliest inception, our dedicated bioconjugation team is committed to supporting your project from discovery and development to preclinical and clinical cGMP manufacture.

Peptides

Sterling’s 25+ years of experience in peptide manufacturing and its state of the art facilities, enable us to deliver the analysis, purification, and manufacturing of novel, long chain peptides.

The Molecule
Lifecycle

We accelerate your product’s path to market by delivering unrivalled support at every stage of the pharmaceutical lifecycle.

A full view of the lifecycle

Discovery

Sterling’s comprehensive analytical and medicinal chemistry expertise, and strong focus on scientific collaboration, enables success in the discovery phase with an eye on containing costs, adhering to deadlines and impact on future phases in the lifecycle.

Preclinical

We pair process development services, including proof of concept, quality by design, and design of experiments, with CMC support for the IND process to establish an efficient, cost-effective, and scalable pathway to market.

Phase One

As our customers prepare for phase I clinical trials, we help them select an appropriate regulatory starting material (RSM), manufacture an appropriate amount of product for clinical trials and generate the necessary regulatory data to enhance their chance of success.

Phase Two

After a product moves through phase I, we continue to accelerate the development of materials for clinical trials and generate critical regulatory data, with process optimisation being a key focus for our scientific and engineering teams.

Phase Three

In this critical phase, we finalise data and process validation, and prepare for commercial manufacture. Scale, efficiency, quality control, integrity, and compliance are all top priorities as we navigate the last phase prior to commercial launch.

Launch

At this stage process optimisation is key to enhance efficiency and save costs, whilst ensuring the quality of the product and adherence to regulatory controls in terms of process change.

Our integrated network of facilities across the UK, USA and Europe have a wide range of capabilities and capacities to suit all our customers needs. Our global teams work together to develop projects across facilities and borders, where required, to make best use of the expertise at each of our locations. Wherever your project is based you will experience the same values and culture Sterling is known for.
