Molecular Insight Reports Positive Data From Tumor Drug Clinical Program

Molecular Insight Pharmaceuticals has reported positive results from two preclinical studies that demonstrated the potential of indium-111-edotreotide as an imaging tool to predict Onalta absorption in body tissues and to aid in determining appropriate patient dose.
The studies evaluated the tissue distribution and pharmacokinetics of indium-111-edotreotide in two animal models. One study included in vitro studies and evaluated another potential imaging surrogate, indium-111-pentetreotide (Octreotide).
Tissue distribution comparisons of the compounds in all organs were virtually identical except in the kidneys, where indium-111-edotreotide predictably and consistently overestimated the Onalta absorbed radiation dose.
Onalta is in development as a targeted radiotherapeutic for the treatment of carcinoid and pancreatic neuroendocrine tumors. The in vitro and in vivo studies are part of Molecular Insight's clinical program to support a planned US dosimetry trial later in 2008.
John Babich, president and chief scientific officer of Molecular Insight, said: "These studies compared the tissue distribution and pharmacokinetic profiles of induim-111- and yttruim-90- labeled edotreotide in order to determine whether indium-111-edotreotide is a suitable imaging predictor for the organ distribution of yttrium-90-edotreotide, the radiotherapeutic peptide."
