ACUTE CHRONIC
** PF614 used for post-surgical pain is anticipated to have four key advantages over traditional opioids: (a) pre-dosing at the start of surgery to reduce pain generation from the beginning vs. chasing pain that is already moderate to severe at the end of surgery,
(b) having a longer duration of action to allow patients to stop or transition off opioids before leaving the hospital or clinic and continue using only non-opioid drugs at home, (c) reducing overall opioid use, and (d) potentially reducing overall healthcare costs.

Expanded Opportunities
Investor Presentation | Apr 2026
Improving Drug Delivery and Lifecycle Management
TAAP MODIFICATION ATTRIBUTES
OPPORTUNITY
Reaches the gastrointestinal tract/epithelial cells intact
Chemistry controlled GI delivery for 'Immediate' or 'Extended-Release'
Improves aqueous solubility
Enhances the drug's permeation through the epithelial lining
Our TAAP platform enables new chemical entity (NCE) solutions that allow us to obtain new patents and extend market positions, revitalize approved medications and repurpose approved medications for the benefit of patients and care givers. Specifically, Ensysce has used to develop a highly novel product for OUD.
Possible oral delivery of injectable drugs
Enhance activity of drugs on GI tract
Extend half-life to improve dosing
