WHO preferred product characteristics: endectocide for malaria transmission control (here)
This document defines the key questions that an endectocide (using ivermectin as a prototype) research agenda should address to generate the appropriate evidence required to define a WHO policy position on the role of an endectocide in the reduction of malaria transmission.

Malaria Policy Advisory Committee meeting report (September 2016) (here)
On 14–16 September 2016, the WHO Malaria Policy Advisory Committee (MPAC) convened to review updates and progress, and provide guidance with respect to specific thematic areas of work carried out by the Global Malaria Programme.
The meeting focused on: (1) an update on the RTS,S vaccine pilot implementation programme; (2) an update on the malaria elimination in the Greater Mekong subregion; (3) a review of Malaria elimination: an operational manual; (4) the results from a multi-country evaluation of the impact of insecticide resistance on malaria vector control; (5) an update on the Strategic Advisory Group on malaria eradication; (6) an update on the development of guidelines for malaria vector control; (7) the development of the Global Vector Control Response; (8) a proposed evidence review group to consider the cardiotoxicity of antimalarial medicines; (9) a report on the WHO technical consultation on detection and surveillance of HRP2/HRP3 deletions; (10) recommendations for the surveillance, monitoring and evaluation taskforce; (11) a proposed evidence review group to review Plasmodium knowlesi; (12) the proposed target product profile for ivermectin; and (13) proposed plans for the World Malaria Report.

Malaria Journal Collection: Ivermectin to reduce malaria transmission
Hundreds of millions of people have received ivermectin every year in campaigns against onchocerciasis and lymphatic filariasis with excellent safety profile. It is also an endectocide, a drug capable of killing mosquitoes feeding on treated subjects.
In the face of the challenges posed by insecticide resistance and residual transmission, mass drug administration of endectocides holds potential as a complementary strategy for malaria elimination.
Mounting evidence suggests that mass-treatment of humans (or their livestock) with ivermectin can reduce vector survival and help reduce malaria transmission. There are however numerous knowledge gaps regarding the appropriate dosing, trial design and regulatory pathway for such a novel approach.
This ‘Ivermectin to reduce malaria transmission’ thematic series in the Malaria Journal aims at providing a comprehensive assessment and factors to consider in adapting this tool for a potential new indication.
