Extentus Pharma

Extentus Pharma, previously known as Tandem Nano, is a private University of Liverpool spin-out focused on reformulating existing active ingredients using proprietary solid drug nanoparticle and long-acting nanoformulation technologies. The company aims to improve oral and injectable delivery of poorly soluble compounds, reduce dosing frequency, improve exposure, and lower treatment cost. Its platform has applications across pharmaceuticals and, historically, agrochemicals, but its healthcare work includes long-acting medicines for malaria, tuberculosis, and hepatitis C. Extentus Pharma appears to operate primarily as a platform and partnering company rather than a late-stage clinical developer, with commercial activity centered on technology licensing, reformulation, and collaborative development.
