(NASDAQ: MEIP), a pharmaceutical company focused on leveraging its extensive development and oncology expertise to identify and advance new therapies for cancer, today announced the publication of two data abstracts related to MEI Pharma's clinical stage drug development programs to be presented at the 2018 ASCO Annual Meeting to be held June 1-5, 2018 in Chicago. Study investigators will present updated results from the Phase 1b study evaluating ME-401 in relapsed/refractory indolent B-cell malignancies and from an investigator-initiated study of ME-344 in patients with HER2-negative breast cancer.

"The ASCO Annual Meeting is an important event for MEI Pharma this year and we are excited to present promising updated data from both our ME-401 and ME-344 programs at the meeting next month," said Daniel P. Gold, Ph.D., president and chief executive officer of MEI Pharma.
