Vinblastine sulphate (Velbe)

Vinblastine sulphate (Velbe) is an intravenous anti-cancer drug derived from the periwinkle plant. It is being studied for the treatment of Kaposi’s sarcoma and lymphoma, alone or in combination with other anti-cancer drugs.1 Studies have also assessed the impact of injecting vinblastine directly into Kaposi’s sarcoma lesions in the mouth and throat, with positive results.2 3

Side-effects include low white blood cell counts and occasional hair loss. A single case report has also suggested that combining vinblastine with protease inhibitors may increase the risk of blood disorders and digestive system problems.4

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
