Title: Labelled adrenomedullin derivatives and their use for imaging and therapy
Inventor: DUPUIS JOCELYN
IPC: A61K51/08
Filed: 2008-05-12
Abstract: The present invention relates to an adrenomedullin derivative including a n adrenomedullin peptide, or a fragment thereof chelated or otherwise bound to at least one active agent. Examples of active agents include a paramagnet ic element, a radioactive element and a fibrinolytic agent, among others. Pa ramagnetic agents have a distribution that is relatively easily shown throug h Magnetic Resonance Imaging (MRI). Radioactive agents have applications in imaging and delivery of radiations, depending on the specific element includ ed in the active agent. Delivery of fibrinolytic agents mainly to a specific organ, such as for example to the lungs, allows to substantially improve th e specificity and efficacy of thrombolytic therapy by allowing local deliver y of the fibrinolytic agent, thereby reducing the risks of major bleeding in the therapy of the organ. If the organ is the lungs, a non-limiting example of pathology treatable with the fibrinolytic agent is pulmonary embolus.
