Phase I

We prioritise participant safety while delivering on your objectives for the study. We conduct a full range of early phase trials including First-in-Human (FIH), food effect, drug-drug interaction and pharmacokinetic studies. Our services also include full study design, IMP management, ethics and CTA submissions in order to provide you with a fully project managed phase I service.

We have a broad range of experience with many therapeutic areas in phase I trials, including CNS, respiratory, dermatology, vaccines and anti-infectives as well as our specialty areas of oncology, rare oncology and rare disease.

Our proven track record in adaptive trial design has benefitted many of of clients. You can learn more about how this approach took one of our biotech clients from Healthy Volunteer to Patient cohort results in 24 months for a rare respiratory condition here.

Our phase I experience

As a leading clinical pharmacology facility, we have worked on a wide range of early phase clinical trials, including oncology phase I trials such as a multi-centre, non-randomised dose-escalation study for non-hodgkin’s lymphoma and chronic lymphocytic leukaemia (read the case study).

We also have experience in clinical pharmacology for rare diseases including this study investigated the pharmacokinetic properties of a study drug, followed by an expansion cohort treating subjects with idiopathic pulmonary fibrosis (IPF) (read the case study).

As experts in their fields, our clinical researchers and project managers also run webinars and publish research papers on the process of clinical development and stage I studies, driving the industry forward. To learn more, this on-demand webinar discusses how to operationalize your early phase oncology study in a clinical setting to meet business objectives.

A critical early phase

We appreciate and understand that for small to medium-sized organisations, early phase trials can be critical in securing investment for the future development of their product.  Our lean management structure means we are a highly flexible team who will adapt to remove bottlenecks and shorten timelines so you can meet your investors’ expectations.

Once you are ready to move on to your next stage of clinical development, we also offer other non-early phase clinical pharmacology services including, drug-drug interaction, food effect and pharmacokinetics studies. Clinical data management, trial design and more, also form part of our fully integrated portfolio.

As a full-service CRO, we are very well equipped to take your study beyond phase I. Our phase II and phase III services mean that, with us, you can take your product from preclinical research to launch.

Phase I &
Clinical Pharmacology

We have a purpose-built clinical pharmacology unit (CPU) equipped for early-phase clinical trials. Our unit is designed to seamlessly move between trial services – from volunteer and patient recruitment to screening, clinical conduct, and on-site laboratories. We also work with hospitals throughout the UK, EU, and beyond.

Decentralised phase I trials

In addition to our purpose-built Clinical Pharmacology Unit, we can also coordinate decentralised phase I trials, where appropriate for the protocol and patient group. This form of clinical trial can remove roadblocks in participation, such as travel times, cost and inconvenience, making patient recruitment smoother.
