We were recommended to Onyx Scientific by an industry contact who had been very impressed with how they operated and delivered compounds. The team were able to take our project on at short notice and support us right away without any fuss. We have found the team to be responsive, competent and straightforward to deal with, which has been invaluable to our project.

–Tony Clarke, Director at Ricanto

Onyx Scientific has a niche in the market. As a contract manufacturing organisation that doesn’t have to bear the high costs of running a pilot plant, it can deliver high quality materials for IND-enabling toxicology studies and early phase development in a cost-effective manner. We would definitely recommend Onyx for anyone considering their options for scale-up and GMP synthesis.

–Matthew Fyfe, Head of Chemistry at Topivert

Onyx Scientific is a truly outstanding partner in early API development and manufacture, combining high levels of technical ability, experience and commitment with a very collaborative approach and a focus on delivery. I have no hesitation in recommending them.

–Peter Spargo, Independent Consultant

We have found Onyx to be a cost-effective CMO for API scale-up as well as related analytical and solid-state development related to ESN364, Euroscreen’s clinical candidate currently in clinical trials. In fact, we found Onyx to be cost competitive even when compared against certain Indian CMOs whilst offering the added advantage of proximity in terms of location (and time zone), ease of communication as well as their experience and know-how.

–Hamid Hoveyda, Director of Chemistry at Euroscreen SA

AstraZeneca has worked with Onyx Scientific for many years for early-phase process development and supply of drug substance. This is clearly an area of expertise for Onyx and we continue to be impressed by their excellent technical capability, combined with their strong customer focus and collaborative approach. These qualities result in Onyx routinely meeting or exceeding our project requirements.

–Bill Moss, Process Chemistry Director at AstraZeneca

As we have moved towards advancing our clinical trial schedule, we have been very pleased with the continued commitment, expertise and support that Onyx Scientific has provided. The team’s flexibility and attention to detail throughout the process, including the adherence to stringent cleaning validation procedures, has assisted us in keeping our project on-track.

–Michael Roe, Chemistry & CMC Technical Manager at KalVista Pharmaceuticals

We were delighted with the service provided by Onyx Scientific in conjunction with Reach Separations in carrying out full characterisation and identification. The joint effort allowed us to undertake impurity synthesis to get a positive identification of impurity followed by the purification of a sample by prep LC. The whole process we found to be quick, efficient and cost effective.

–Sam Hubbard, Analytical Laboratory Manager at Oxford Analytical Ltd

The important thing for us when working with Onyx Scientific was the project was delivered on time and within budget. The team at Onyx communicated well and we were pleased with the quality of the final product.

–Dave Hamre, Pharmaceutical Project Manager at Special Products

We have worked with Onyx Scientific for a number of years and have been very impressed by their excellent flexibility and responsiveness throughout. They have demonstrated strong technical capability in carrying out PR&D scale up and GMP manufacture on multiple Phase I projects. By utilising their solid state offering alongside the PR&D work, this ensured a very efficient program with respect to salt selection. Vitally for us, their team has supported our application process through fast turnaround on any requests.

–Harshad Patel, Project Leader at Pulmagen Therapeutics

Onyx Scientific have shown themselves to be technically very capable when it comes to carrying out analytical projects. They took the time to understand our specific requirements and have come up solutions to overcome any challenges. Communication with the team has been particularly excellent given our contacts are easily accessible and contactable at any time. Importantly for us, speed of delivery was exceptional.

–David Childs, Director CMC at Shield Therapeutics

We were very impressed with the speed at which the team at Onyx Scientific initially responded to our enquiry. We required our compound within six weeks and were delighted to take delivery of our material well within this very tight timescale. Onyx’s team were friendly and knowledgeable, its facilities, equipment and reports were first class and the project on the whole ran incredibly smoothly.

–Dr Gavin Donoghue, Pharmaceutical Chemist at Syntopix Group PLC

Onyx Scientific provided an excellent service, responding very quickly to our needs with the flexibility that the nature of our work requires. They have coped easily with the higher volume of work and the data we are getting is as good as we could ask for. Its team continues to go beyond the call of duty and will enable us to make great progress going forwards. An outstanding experience all around.

–Dan Gooding, CEO at Nuformix Ltd

Cyclacel has worked closely with Onyx for a number of years. They have provided synthetic chemistry and analytical expertise for our late stage research programs and early development projects such that we could rapidly progress lead candidates through pre-clinical testing and into first in man studies. I have always found Onyx to be very customer focussed, flexible and responsive.

–Dr Ben Skead, Head of CMC at Cyclacel

The team at Onyx Scientific definitely provide value for money. They are reliable, meet deadlines making them a safe pair of hands and more cost effective in the long run than potentially cheaper competitors.

–Dr Nigel Westwood, Drug Supply Manager at Cancer Research UK

Over the ten years we have worked with Onyx Scientific, they have continuously expanded their services and kept up to date with the demands of the industry. As such, Onyx now provide an end to end chemistry solution and continue to deliver an outstanding service.
