* Vertex Pharmaceuticals Inc., of Cambridge, Mass., launched a Phase I trial of VX-497, an oral inosine monophosphate dehydrogenase (IMPDH) inhibitor for the treatment of autoimmune diseases. The 50-patient U.K. study will test pharmacokinetics and tolerability in escalating doses. IMPDH is an enzyme involved in the immune response that enables lymphocyte proliferation and recruitment by catalyzing a key step in one of two DNA nucleotide biosynthesis pathways. According to Vertex, IMPDH inhibition appears to selectively suppress immune system cells while leaving other cells unaffected and may play a role in downregulating inappropriate immune responses.
