History of Nycomed Amersham Imaging:
2001 The transfer of the imaging products onto those ones new set up Amersham Health AG.
2000 The sale of the diagnostic fields at Axis-Shield. The NycoCard marketed products through Nycomed AG in the Switzerland still.
1999 The solution of the fusion and incorporation of imaging as an own department.
1998 The fusion with Amersham, change of the name in Nycomed Amersham AG.
1996 The Name Hafslund is omitted, the company occurs only under the name Nycomed.
1990 The company Hafslund Nycomed is starting with imaging products.

Short name: Code 7228, generic name: Ferumoxytol, central moiety: Fe
Code 7228 is the code name for a substance in the development pipeline (AMAG Pharmaceuticals, Inc.) for use as a contrast agent in magnetic resonance angiography (MRA). Ferumoxytol, as a true blood pool agent, resides in the vascular space for an extended period of time and does not leak out into adjacent tissues like currently used gadolinium-based contrast agents. The product is being evaluated in MRA applications for the detection of blood flow in the heart muscle, in exploratory studies for the diagnosis of vulnerable plaque and as a next generation lymph node agent.
Code 7228 is currently in approval phase for use as an iron replacement therapeutic in chronic kidney disease patients receiving erythropoetin.
It is presently contemplated that Ferumoxytol will compete with the contrast agents Vasovist™ from EPIX Pharmaceuticals, Inc. and NC100150 Injection from Nycomed Amersham.

MS-325 is the formerly code name of gadofosveset trisodium (new trade name Vasovist). MS-325 belongs to a new class of blood pool agents for magnetic resonance angiography (MRA) to diagnose vascular disease. Gadofosveset trisodium has ten times the signal-enhancing power of existing contrast agents as well as prolonged retention in the blood. This enables the rapid acquisition of high resolution MRA's using standard MRI machines.
Gadofosveset trisodium, which is gadolinium-based, stays in the blood stream as a result of transient binding to albumin. Albumin binding offers an additional benefit beyond localization in the blood pool. The contrast agent begins to spin much more slowly, at the rate albumin spins, causing a relaxivity gain that produces a substantially brighter signal than would be possible with freely circulating gadolinium. MS-325 is an intravascular contrast agent intended for use in MRI as an aid in diagnosing aortoiliac occlusive disease in patients with known or suspected peripheral vascular disease (PVD) or abdominal aortic aneurysm (AAA).
Currently clinical trials completed for peripheral vascular disease and coronary artery disease. Additional trials are also being conducted to evaluate MS-325 as an aid in diagnosing breast cancer and suggested that it might be feasible to combine the use of MS-325, injected during peak stress, with delayed high-resolution imaging to identify myocardial perfusion defects.
Vasovist (MS-325) would compete with the contrast agents Ferumoxytol (Code 7228) from AMAG Pharmaceuticals, Inc. and NC100150 Injection from Nycomed Amersham, but their further development is uncertain.
Partners in development: EPIX Pharmaceuticals, Inc., Mallinckrodt Inc., and Bayer Schering Pharma AG. Bayer Schering Pharma has the worldwide marketing rights for the product.
Formerly known under the Mallinckrodt trademark name, AngioMARK®.

Short name: Mn-DPDP
This MRI contrast agent is a chelate complex of the paramagnetic metal ion manganese (Mn) and fodipir. Mn-DPDP (Teslascan) shortens the longitudinal relaxation time and is used for the T1 weighted enhancement of MR images. Mangafodipir trisodium accumulates after intravenous injection in the healthy tissue of the liver and improves the detection, localization, characterization, and evaluation of lesions of the liver, pancreas, but can also be used in cardiac MRI.

The United States Food and Drug Administration (FDA) has granted marketing clearance 1997, to Nycomed Amersham's MRI contrast medium. Nycomed/Amersham, now GE Healthcare markets the product under the trade name Teslascan®.

Short name: NC100150, PEG-feron, generic name: Feruglose, preliminary trade name: Clariscanâ„¢
NC100150 injection is the code name for an USPIO (ultrasmall superparamagnetic iron oxide) MRI contrast agent under development. Microvessel permeability depends on functional and morphologic characteristics of cancer vessels and on physicochemical properties of the injected contrast medium molecule.
USPIO particles have a favorable pharmacological and tolerance profile and are being tested clinically of the potential for the quantitative characterization of tumor microvasculature and specifically for measures of the microvessel permeability. Iron-based products take advantage of their large molecular size, which prevents diffusion into body tissues. These agents are disposed of by the liver and spleen as particulate matter.
NC100150 Injection (Nycomed Amersham, Amersham Health ) consists of USPIO particles that are composed of single crystals (4- to 7-nm diameter) and stabilized with a carbohydrate polyethylene glycol (PEG) coat. The iron oxide particles have to be suspended in an isotonic glucose solution. The final diameter of an USPIO particle is approximately 20 nm. Blood pool half-life is more than two hours in humans; the particles are taken up by the mononuclear phagocyte system and distributed mainly to the liver and spleen.
NC100150 would compete with the contrast agents Ferumoxytol from AMAG Pharmaceuticals, Inc. and Vasovistâ„¢ from EPIX Pharmaceuticals, Inc., but at this time the development of NC100150 Injection/Clariscan™ is discontinued.
