One clinical trial (for refractory follicular lymphoma) was temporarily put on hold due to cardiac problems but resumed recruiting in 2009.[4]

In 2010 favourable results were announced from the phase II trial for Hodgkin's lymphoma.[5]

MGCD0103 has also been used as a research reagent where blockage of members of the HDAC-family of histone deacetylases is required.[6]

Mechanism of action

It works by inhibiting mainly histone deacetylase 1 (HDAC1), but also HDAC2, HDAC3, and HDAC11.[7]
