The only piperonyl butoxide (PBO) LLIN on the market with a controlled release design

Early in our journey to end malaria, we recognised the threat insecticide resistance would pose to any progress toward eradication or elimination of the disease. In 2007, we introduced the first PBO LLIN to market. Compared to a pyrethroid-only net, a PBO LLIN has an increased killing effect on malaria vectors that have become resistant to pyrethroid insecticides and more effectively reduces malaria incidence and prevalence.

PermaNet® 3.0 demonstrated efficacy in lab studies, experimental hut studies and long term field trials across malaria-endemic countries and with a range of mosquito species and insecticide resistance levels. PermaNet 3.0 was part of a large-scale randomised control trial in Uganda in areas with moderate to high insecticide resistance.

Backed by 10 years of research, PermaNet® 3.0 is effective during its intended lifetime of 3 years thanks to our controlled release design that ensures continuous bioavailability of PBO and delthamethrin on the fabric surface. PermaNet 3.0 is prequalified by WHO (Reference 005-002).

PermaNet 3.0 scientific publications

A substantial body of scientific evidence demonstrates the increased efficacy of the PBO LLIN, PermaNet® 3.0 against pyrethroid resistant malaria mosquitoes (compared with pyrethroid only LLINs). Scientific publications include lab, semi-field, and community studies.

Three long-term field studies

WHOPES Phase III are prospective three-year studies. The studies conducted on PermaNet® 3.0 in Ghana, India, and Kenya confirm the long lasting efficacy, fabric integrity, and community acceptability of PermaNet® 3.0.
