Structure of TMC207/R207910

Ji et al. suggested in their publication in 2006 that TMC207/R207910 may play a role in the treatment of leprosy.

Now Gelber et al. have shown that indeed TMC207/R207910 has a bactericidal effect for Mycobacterium leprae-infected mice. In their dose frequency study they examined three different treatments (five times weekly, once weekly, and once monthly) and demonstrated that all dosage schedules were bactericidal for M. leprae. They furthermore gathered evidence that TMC207/R207910 prevented multiplication of the bacteria for a prolonged period of time after the treatment had ended.

Having shown the bactericidal effects of TMC207/R207910 for M. leprae during logarithmic multiplication, the authors conclude that these findings should merit a clinical trial with leprosy patients once long-term safety data for TMC207/R207910 are available. Especially since Mycobacterium leprae has a longer generation time in comparison with Mycobacterium tuberculosis, a successful addition of TMC207/R207910 to a potentially monthly regimen with shorter duration than the current standard therapy might become possible.
