Scientists have discovered a new anti-malarial compound that
could treat patients with a single US$1 dose, including those with strains of
the mosquito-borne disease that are resistant to current drugs.
Although it is still
years from reaching the market, results from tests conducted on human blood in
the laboratory and in live mice suggest it is highly potent, researchers
reported in the journal Nature on Wednesday.
Reuters reports in a vote
of confidence for the project, German drugmaker Merck KgAA has secured the
right to develop and commercialize the compound, assuming it succeeds in
further tests.
The plan is to advance
the experimental medicine into clinical trials within the next year to assess
its safety and see just how well it can fight malaria in the human body. Many
drugs fall down at this stage in development.
Finding new medicines for
malaria is particularly important because of rising resistance to even the best
existing treatments. Researchers recently reported that malaria with total
resistance to the drug artemisinin had taken hold in Myanmar and spread close
to the Indian border.
Encouragingly, the new
compound works in a different way from other drugs by targeting part of the
machinery that makes proteins within the parasite, which means it should be
effective against current drug-resistant disease.
Known as DDD107498, it
was developed by the University of Dundee's Drug Discovery Unit and the
non-profit Medicines for Malaria Venture.
The scientists behind the
project estimate it should cost about US$1 per treatment, putting it within reach
of the most affected patients, who live in poor countries.
While there have been
significant reductions in the numbers of people falling ill and dying from
malaria, it still kills around 600,000 a year - most of them children in the
poorest parts of sub-Saharan Africa.
Drug companies making
existing malaria drugs include Novartis and Sanofi, both of which have special
programmes in place to make their products more affordable.
