Successful results of a University of Liverpool-led trial that utilised nanotechnology to improve drug therapies for HIV patients could revolutionise HIV treatment.
Currently, the treatment of HIV requires daily oral dosing of HIV drugs, and chronic oral dosing has significant complications that arise from the high pill burden experienced by many patients across populations with varying conditions leading to non-adherence to therapies.
Manipulation of matter
Nanotechnology is the manipulation of matter on an atomic, molecular, and supramolecular scale. Nanomedicine is the application of nanotechnology to the prevention and treatment of disease in the human body. By developing smaller pills that are better for patients and less expensive to manufacture, this evolving discipline has the potential to dramatically change medical science and is already having an impact in a number of clinically used therapies and diagnostics worldwide.
Developing new therapies
Research efforts by the Liverpool team have focused on the development of new oral therapies, using Solid Drug Nanoparticle (SDN) technology which can improve drug absorption into the body, reducing both the dose and the cost per dose and enabling existing healthcare budgets to treat more patients.
The trial results confirmed the potential for a 50 percent dose reduction while maintaining therapeutic exposure, using a novel approach to formulation of two drugs: efavirenz (EFV) and, lopinavir (LPV). EFV is the current WHO-recommended preferred regimen, with 70% of adult patients on first-line taking an EFV-based HIV treatment regimen in low- and middle-income countries.
The trial is connected to the University’s ongoing work as part of the multinational consortium OPTIMIZE, a global partnership working to accelerate access to simpler, safer and more affordable HIV treatment.
