The DETERx drug delivery platform consists of a multi-particulate matrix formulation in a capsule. While developed primarily to provide tamper-resistant properties to protect against common methods of tampering such as chewing, crushing, insufflation and extraction for IV injection, the multi-particulate design is expected to enable patients with difficulty swallowing to open the capsule and administer the contents on food or via a gastronomy tube, while maintaining the extended-release properties of the product. DETERx technology can be used with drugs that are commonly abused such as opioids and amphetamines, as well as drugs that have narrow therapeutic windows that would benefit from protection against misuse such as breaking, crushing, grinding or dissolving the product. The formulation platform is covered by U.S. and international patents and patent applications. Oxycodone DETERx (COL-003) is the first of a number of product candidates using the DETERx platform.

Collegium Pharmaceutical, Inc. is a specialty pharmaceutical company focused on developing a portfolio of products that incorporate its patent-protected DETERx formulation platform for the treatment of chronic pain. The DETERx oral drug delivery technology provides extended-release delivery, unique tamper-resistant properties, and flexible dose administration options.
