SAN DIEGO, Jan. 30, 2013

SAN DIEGO, Jan. 30, 2013 /PRNewswire/ --MEI Pharma, Inc. (Nasdaq: MEIP), an
oncology company focused on the clinical development of novel therapies for
cancer, announced today that Professor Bryan R.G. Williams, Ph.D., will not
stand for re-election to MEI Pharma's Board of Directors upon the expiration
of his term at the Company's next Annual Meeting of Stockholders. Professor
Williams has been a member of the Board since March 2006 and has served as
Chairman since November 2006.


"It has been a tremendous experience working with the Board and management
team of MEI Pharma," said Professor Williams. "My decision to retire from the
Board is driven in part by my increasing responsibilities as Director of the
Monash Institute of Medical Research in Melbourne. I also believe that this is
the right time to hand over the leadership of the Board to a successor with
extensive drug development experience as the Company advances its drug
candidates into later stage clinical testing. I wish the Company and its
shareholders continued success in the future."

"It has been a pleasure and a great honor to have served with Bryan," said
Daniel P. Gold, Ph.D., President and Chief Executive Officer of MEI Pharma.
"Bryan's leadership on the board was critical during the Company's transition
from R&D to clinical development and he has been a source of strength for our
Board over the course of the past seven years. On behalf of all of us, I would
like to thank him for the significant contributions he has made to the
Company. I am confident that we will find a qualified and proven successor as
Chairman to help us continue in the strategic direction that Bryan helped to
put in place."

Effective upon Professor Williams' retirement, Christine A. White, M.D., will
serve as Lead Director until a new Chairman has been appointed. The Board's
Nomination Committee has commenced a process to select a successor, reviewing
both internal and external candidates, including consideration of candidates
proposed by new investors Vivo Ventures and New Leaf Ventures.

"Christine is a highly experienced director and well suited for this role. Her
guidance will help to ensure a smooth transition and provide the Board time to
identify an ideal candidate for the next stage of our Company's growth," Dr.
Gold added. "In addition, her knowledge of oncology drug development and
regulatory affairs coupled with her experience as a clinical oncologist
continue to pay dividends as we diligently prepare for the initiation of
several Phase II clinical trials in the months ahead."

Dr. White was appointed as a director in August 2010. She was with Biogen Idec
from 1996 to 2005, most recently as Senior Vice President, Global Medical
Affairs, where she played an integral role in the clinical development,
regulatory affairs and commercialization of oncology drugs Rituxan^® and
Zevalin^®. Dr. White also serves as a member of the board of directors of
Arena Pharmaceuticals. Dr. White earned her B.A. in Biology and her M.D. from
the University of Chicago and is Board certified in both Internal Medicine and
Medical Oncology.
