Onyx have a tremendous reputation as a premier CDMO, and the results they achieve consistently exceed our highest expectations. If you’re scaling drug substance to take into GMP manufacture, look no further than Onyx.

–Peter Rands, Managing Director at Small Pharma Ltd

Onyx Scientific is one of the top development companies within the life sciences industry. They have a clear niche in how they integrate their process development, solid state and analytical services. I find their no nonsense, straight forward approach helpful and efficient and it makes my role as a consultant much easier. Their technical expertise is very strong, and I'd have no hesitation when it comes to recommending them for similar projects.

–David Lathbury, Consultant

We appreciated the realistic assessment we received from Onyx. Their attention to detail during the synthesis campaign was excellent - they are very good technically and their honest approach to projects encouraged us to work with them again this year!

–Christopher Luckhurst, Principal Chemist at Mission Therapeutics

I’ve worked with the Onyx team for 7 years. They have a great team of skilled chemists, analysts and solid-state scientists. Onyx have a great range of capabilities and have provided superb support for me across a number of projects. Their flexible approach and competitive pricing makes them an attractive, reliable CDMO to work with.

–Christopher Wallis, Industry Consultant

I have no hesitation in recommending working with Onyx Scientific. Flexible and knowledgeable, Onyx has the capabilities needed to complete API chemical development and kilogram-scale GMP manufacturing projects to very high standards and in a cost-effective manner. What’s more, the team is made up of high-quality scientists and the direct interaction approach to project management that they take makes it feel as though I have my very own chemistry team there.

–Peter Spargo, Senior Vice President Chemistry Manufacturing at Verona Pharma

We were recommended to Onyx Scientific by an industry contact, who had been very impressed with how the team had operated. 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

We have found Onyx Scientific 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 Scientific to be cost competitive even when compared against certain Indian CMOs. In addition to this, Onyx Scientific offers 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 the supply of drug substances. This is clearly an area of expertise for Onyx Scientific and we continue to be impressed by their excellent technical capability, combined with their strong customer focus and collaborative approach. These qualities mean that Onyx Scientific routinely meet or exceed 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. We found the whole process to be quick, efficient and cost-effective.

–Sam Hubbard, Analytical Laboratory Manager at Oxford Analytical Ltd

Importantly, when working with Onyx Scientific, our 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 the team's 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 programme with respect to salt selection. Vitally for us, their team has supported our application process through fast turnaround.

–Harshad Patel, Project Leader at Pulmagen Therapeutics

Onyx Scientific has proven to be technically very capable when it comes to carrying out analytical projects. The team took their time to understand our specific requirements and came up with solutions to overcome any challenges. Communication with the team has been particularly excellent.
