Novelos Therapeutics, Inc.
(OTCQX: NVLT), a pharmaceutical company developing novel drugs for the treatment and diagnosis of cancer, today announced that an oral presentation on research conducted by Novelos and its collaborators is being made by Dr.
at the EMIT: Targeted Radiotherapy international conference taking place
January 29 to 31
, D.C. This presentation by invitation from EMIT describes the mechanistic foundation for Novelos' diapeutic (diagnostic + therapeutic) technology platform together with animal data and initial findings in advanced cancer patients that demonstrate selective and prolonged accumulation of Novelos' PET imaging I-124-CLR1404 (LIGHT), therapeutic I-131-CLR1404 (HOT) and optical imaging CLR1502 (GLOW2) compounds in a range of tumor types. Dr. Pazoles is the Senior Vice President of Research and Development for Novelos.
"LIGHT, HOT and GLOW2 were designed to exploit a feature shared by most, if not all, cancer cells including cancer stem cells, which results in the selective uptake and prolonged accumulation of our proprietary, small-molecule delivery vehicle in a wide range of malignant tumors compared with normal tissues," said Dr. Pazoles. "By incorporating a unique functional property in each – PET imaging, radiotherapy or optical imaging – we have generated an array of potential therapeutic and diagnostic products that could, alone or in combinations, significantly improve the detection and treatment of cancer in multiple ways."

In his presentation, titled
Cancer-Targeted Diapeutics: Radioiodinated Phospholipid Ether Analogs for Broad-Spectrum Imaging and Therapy
, Dr. Pazoles presents data showing that LIGHT, HOT and GLOW2 all share a common cancer-targeted core chemical structure. Each attaches a unique moiety to this delivery vehicle – LIGHT, a PET imaging agent (iodine-124), HOT, a radiotherapeutic agent (iodine-131) and GLOW2, an optical imaging agent (near-infrared tracer). Results described with LIGHT demonstrate broad-spectrum tumor PET imaging in dozens of animal tumor models, and recent human findings from ongoing Phase 1-2 clinical trials show selective uptake and retention by primary tumors and metastases in advanced non-small cell lung and brain cancer patients. HOT results shown include single-dose efficacy in a wide range of animal tumor models, and clinical trials to date demonstrate selective accumulation in cancerous tumors, including metastases. Dr. Pazoles' presentation highlights the potential diapeutic application of LIGHT and HOT, based on their chemical identity, to provide individualized treatment to cancer patients. For example, LIGHT serves as an ideal biomarker to potentially identify patients most likely to benefit from therapy with HOT. Dr. Pazoles' talk also describes how selective uptake of GLOW2 could provide better definition of tumor margins in real time during cancer surgery, enabling more complete and selective removal of malignant tissue and potentially improving patients' prognosis. Data illustrating the potential use of GLOW2 for non-invasive detection of tumors is also featured.
"We are pleased to share the science behind Novelos' cancer-targeted diapeutic platform with the scientific community attending this international conference," said Harry Palmin, President and CEO of Novelos. "We continue to make good clinical progress with LIGHT and HOT across multiple human trials while advancing GLOW2 towards human trials."
