DATSCAN (Ioflupane I 123 Injection) indication expanded to include use in patients with suspected Dementia with Lewy Bodies (DLB)

GE Healthcare’s DaTscan has been approved by the U.S. Food and Drug Administration (FDA) for use in patients with suspected Dementia with Lewy Bodies (DLB). This new indication is in addition to its use with single photon emission computed tomography (SPECT) imaging to visualize dopamine transporters (DaT) in the brains of adult patients with suspected Parkinsonian syndromes. With the expanded indication, DaTscan is now available to more patients, including those with suspected DLB, in the United States.

The clinical signs and symptoms of DLB can be atypical and overlap with other forms of dementia, leading to up to 70% of patients with DLB being misdiagnosed, often as having Alzheimer’s Diseaseⁱⁱ. This new indication enables clinicians to use DaTscan to help differentiate DLB from other forms of dementia. Early and accurate diagnosis of DLB can help ensure specific appropriate treatment and specialized care for patients, while enabling them and their caregivers to more effectively manage the disease and plan for the futureⁱⁱⁱ.

Approximately one in five patients with dementia suffers from DLB, making it the second most common form of degenerative dementia after Alzheimer’s Diseaseⁱ.

Professor James E. Galvin, MD, MPH, Consultant, University of Miami Miller School of Medicine, U.S., said: “Misdiagnosis is a significant issue for those patients with suspected Dementia with Lewy Bodies, causing untold anxiety for the patient and family as well as potentially placing the patient at higher risk of adverse events due to delayed diagnosis. The label expansion for DaTscan moves patients a step closer to an earlier, more accurate, diagnosis which is beneficial for them and their families, setting them on the right treatment path sooner and helping to avoid medications and treatments that could be potentially harmful.”

Mark Hibberd, Chief Medical Officer for GE Healthcare Pharmaceutical Diagnostics, said: “More than one million doses of DaTscan have already been used around the world in the clinical evaluation of Parkinsonian syndromes. We have built on our scientific and medical leadership with DaTscan to pave the path for this new indication, that supports our customers and their patients with more accurate diagnoses of DLB.”

The approval of the use of DaTscan in DLB is the culmination of significant work, including clinical trials, compilation and analysis of data and collating evidence for submission to the U.S. FDA, all demonstrating GE Healthcare’s continued commitment and investment in this space.
