We also on the burden of malaria on the recognise that even where relevant lives of people living in developing commercial R&D occurs, for example countries and on MMV’s vision: for the modestly sized travellers’ a world in which affordable drugs market, little from its output will help eliminate this scourge and eventually goes to the poor in protect children, pregnant women, endemic countries.

We are also well aware of the history of over-promise and under-delivery These caveats notwithstanding, what associated with some malaria control can be said even after only a short programmes in the past. Bearing period of MMV’s existence, is that this history in mind, we are neither the central partnership concept that tempted to promise more than is sustains MMV’s operations does work the spider against malaria. possible nor to overstate our better than most expected.

Thus, the malaria R& D per DALY is around one-twentieth of the global average. It is notable and disturbing that the premier public-private partnership for developing new malaria drugs, the Medicines for Malaria Venture ( MMV ), currently disburses less than $ 10 million per year in funding, and is so limited in funding that it currently aims for only $30 million per year by 2004.” ( p.79, “ The Macroeconomic Report on Health” , WHO, 2002 ). 2 THE MATURATION OF MEDICINES FOR MALARIA WITHIN THE GLOBAL CONTEXT Malaria : The Ignored Killer The year 2001 ended with global community to support health inter- attention becoming increasingly ventions, including R&D that targets receptive to the problem of neglected the very poor.

A balance has to be struck by malaria control programmes in locations where health infrastructure is weak and a great amount of self-purchase and treatment of malaria occurs. On the one hand there is a desire to encourage wide distribution of drugs for ease of access. On the other there is a desire to ensure drugs are used only when needed and that they are used appropriately to avoid the generation of drug resistance. The more options there are for malaria treatment, the less acute this dilemma becomes and one can promote For many of the sub-indications Nevertheless, progress to date has mentioned above, it is very difficult been far better than we could have to define how appropriate projects predicted.
