Shares of Biodexa Pharmaceuticals skyrocketed nearly 50% on Monday, hitting their highest level since early December. 

The Cardiff, UK-based company's stock surge followed the U.S. FDA granting its treatment eRapa a Fast Track designation. 

The drug, a proprietary encapsulated form of rapamycin, is being developed for familial adenomatous polyposis (FAP), a condition that, if left untreated, universally leads to colorectal cancer. 

FAP currently has no effective medical treatment, with the only option being surgical resection of the colon or rectum.

The Fast Track designation aims to expedite the development and review of drugs targeting serious conditions with significant unmet medical needs. 

Biodexa's Phase 2 study of eRapa showed promising results, with a median 17% reduction in total polyp burden and a 75% non-progression rate at 12 months. 

In cohort 2, patients showed an even better response, with a 29% median reduction in polyp burden and an 89% non-progression rate.
