About Novelos Therapeutics, Inc. We are a pharmaceutical company developing novel drugs for the treatment and diagnosis of cancer. We currently have three cancer-targeted compounds, which are selectively taken up and retained in cancer cells (including cancer stem cells) versus normal cells. Thus, our therapeutic compounds directly kill cancer cells while minimizing harm to normal cells. This offers the potential for a paradigm shift in cancer therapy – efficacy versus all three major drivers of mortality in cancer: primary tumors, metastases and stem cell-based relapse. LIGHT is a small-molecule cancer imaging agent. We believe LIGHT has first-in-class potential and expect it to enter Phase 1/2 clinical trials middle of this year. HOT is a small-molecule, broad-spectrum, cancer-targeted radiopharmaceutical that delivers radiation directly and selectively to cancer cells and cancer stem cells. We believe HOT also has first-in-class potential, and we expect it to enter a Phase 1b dose escalation trial in the third quarter of this year and Phase 2 trials in mid-2012 as a monotherapy for solid tumors with significant unmet medical need. COLD, a cancer-targeted chemotherapy that we expect to enter clinical trials late in 2012, works primarily through Akt inhibition. Together, we believe our compounds are able to “find, treat and follow” cancer anywhere in the body in a novel, highly selective way. For additional information please visit www.novelos.com.
