Twenty years into the global HIV/AIDS pandemic, researchers are hopeful about new classes of medicine that block the HI virus before it can enter human cells.
Joep Lange, president of the International AIDS Society, said such drugs may keep patients healthy for longer with fewer side effects.
"The inhibition of HIV entry is the field with the most promise at the moment. One of the main problems with current drugs is their long-term toxicity and particularly their metabolic side effects. It is very unlikely that the entry inhibitors will give those sort of side effects," Reuters quoted Lange as saying.
The drug manufacturers are expected to showcase their latest advances at the 15th International AIDS Conference in Bangkok from 11 to 16 July.
