Updated efficacy results from Allos Therapeutics' FOLOTYN study to be presented at the ASH meeting

Allos Therapeutics, Inc. (Nasdaq: ALTH) today announced that abstracts from studies of FOLOTYN^™ (pralatrexate injection) were accepted for presentation at the 51st Annual Meeting of the American Society of Hematology (ASH) to be held at the Ernest N. Morial Convention Center in New Orleans, La., from December 5-8, 2009.

Four poster presentations will summarize new analyses of data and updated efficacy results from the Company’s pivotal PROPEL study, which served as the basis for U.S. Food and Drug Administration’s accelerated approval of FOLOTYN™ on September 24, 2009, for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma (PTCL). In addition, there will be a poster summarizing results of a Phase 1 study of FOLOTYN in combination with gemcitabine in patients with relapsed or refractory lymphoproliferative malignancies, and an oral presentation highlighting results of a multicenter, dose-finding study of FOLOTYN in patients with cutaneous T-cell lymphoma (CTCL).
