About MEI Pharma

MEI Pharma, Inc. (Nasdaq: MEIP) is a San Diego-based oncology company focused
on the clinical development of novel therapies for cancer. The Company's lead
drug candidate is Pracinostat, a potential best-in-class, oral HDAC inhibitor
being developed for advanced hematologic diseases, such as myelodysplastic
syndrome (MDS) and acute myeloid leukemia (AML). The Company initiated a
randomized, placebo-controlled Phase II trial of Pracinostat in combination
with Vidaza (azacitidine) in patients with previously untreated MDS in June
2013. An open-label Phase II trial of Pracinostat in combination with Vidaza
in elderly patients with AML who are unsuitable for intensive chemotherapy is
open for enrollment. MEI Pharma is also developing ME-344, a mitochondrial
inhibitor derived from its isoflavone-based technology platform. Results from
a first-in-human, single-agent clinical study of ME-344 in patients with
refractory solid tumors were presented in October 2013. In September 2013, the
Company further expanded its pipeline of drug candidates with the acquisition
of PWT143, a highly selective PI3-kinase delta inhibitor. For more
