With a track record of leading hundreds of RTSMs to successful go-live, Poxy Clinical is the industry’s leader in RTSM consulting, specializing in UAT services.

Poxy Clinical is a RTSM consultancy founded in CA. In 2019, the company relocated their headquarters to renowned biotech hub Kendall Square, located in Cambridge, MA to better support the needs of a global client base.

The company’s mission began when sponsors began to reach out after experiencing major RTSM (aka ‘IRT’) issues during their clinical trials. The issues ranged from accidental unblinding, randomization errors, and mis-dosed patients – ultimately compromising patient safety. Over time, it became clear the issues were not RTSM-related, but a lack of resources and validation expertise that contributed to the oversight.
