"We are pleased to be able to present and discuss our findings at the AACR annual meeting", commented Dr. Aiping Young, President and CEO of Lorus. "These studies show our continued commitment to high quality preclinical research that is in-line with our ongoing clinical programs and corporate strategy".
LOR-2040 is a DNA-based drug that specifically targets the R2 component of ribonucleotide reductase, which is required for DNA synthesis and cell proliferation. R2 has also been described as a malignant determinant that is elevated in a wide range of tumors, and through down regulation can cooperate with a variety of cellular cancer causing genes known as oncogenes to enhance tumor growth and metastatic potential. Currently, LOR-2040 is in seven clinical studies, including a Phase II trial in AML, Phase I in MDS and Acute Leukemias, and five Phase I/II trials in solid tumors.
LOR-253 is a small molecule compound that has shown selective and potent antitumor activity in a variety of human cancers, including colon cancer and non-small cell lung cancer, and has an excellent therapeutic window due to its low toxicity. The mode of action of LOR-253 involves the downregulation of cyclin D1, an important regulator of cell cycle progression and cell proliferation, and induction of the tumor suppressor Kruppel like factor 4 (KLF-4). Alterations in KLF-4 expression and the cyclin D1 regulatory pathway have been linked to the development of cancer.
