Lorus Therapeutics Presents Preclinical Data on LOR-253 at American Association for Cancer Research Annual Meeting 2014

TORONTO, ONTARIO -- (Marketwired) -- 04/08/14 -- Lorus Therapeutics Inc. (TSX: LOR) today announced the presentation of preclinical data for LOR-253, the company's lead anti-cancer agent, at the American Association for Cancer Research (AACR) Annual Meeting 2014 in San Diego, CA. Lorus researchers demonstrated the ability of LOR-253 to induce cell death, or apoptosis, in blood cancer cell lines, including Acute Myeloid Leukemia (AML) cells, in vitro and concluded that the studies support further evaluation of LOR-253 as a potential therapy for AML and other hematologic cancers.

LOR-253 is a clinical-stage, small molecule therapeutic that acts through induction of the innate tumor suppressor Kruppel-like factor 4 (KLF4). Lorus is currently pursuing the clinical development of LOR-253 in AML based on recent research that has implicated up-regulation of various transcription factors, including CDX2, as a causative gene in the development or progression of leukemic disease. The CDX2 protein has been shown to silence the KLF4 tumor suppressor gene, which is reported to be a critical oncogenic event in AML.

Today, Dr. Yoon Lee, Lorus' Senior Vice President of Research, presented data demonstrating that LOR-253 exerts anti-proliferative activity against various human leukemia and lymphoma cell lines in vitro with low nM IC50 potency. Further, LOR-253 induces KLF4 mRNA expression in AML cells, resulting in an increase in the expression of p21, a cyclin-dependent kinase inhibitor that is transcriptionally regulated by KLF4. Consistent with these results, LOR-253 was found to induce cell cycle arrest and apoptosis, demonstrating that LOR-253 acted through its intended mechanism of action to kill AML cell lines. LOR-253 also showed strong anti-cancer synergy when used in combination with conventional chemotherapeutics (e.g., daunorubicin, azacitidine, decitabine and cytarabine) used to treat patients with certain hematologic malignancies. With the potential to reactivate the silenced KLF4 gene and induce apoptosis in AML, LOR-253 may offer an important new approach for the treatment of AML and possibly other hematologic malignancies.

Studies are underway to further characterize the pathway that mediates KLF4 induction by LOR-253, to characterize the effects of LOR-253 in combination with approved chemotherapies for AML, and to assess the efficacy of LOR-253 in animal models of AML. In a prior single-agent Phase I clinical study, LOR-253 demonstrated antitumor activity and a robust safety profile in patients with solid tumors. A dose-escalating Phase 1b trial, evaluating safety and efficacy as a monotherapy in AML, MDS and other hematologic malignancies, is anticipated to begin during the summer of 2014.
