Comparator Sourcing and Blinding

Provision of a secure comparator supply has been a core service for many years – we have been able to obtain many difficult products required for clinical trials on a global scale. We also offer a range of solutions for blinding of comparator products. Over-encapsulation requires the flexibility to produce batches ranging from hundreds to millions of capsules in a cost effective and secure fashion.

Sponsor companies involved in the respiratory therapeutics area may require inhaler devices to act as the comparator product within their clinical trials. We have developed innovative methods to produce both blinded and placebo devices for use in double dummy trials.

Clients often approach us with blinding requirements that need an innovative approach and do not fit into the standard methods for blinding trial materials for example obscuring text on blister packs or blinding of vials / syringes.
