  • Patent number: 8147798
    Abstract: The present method for determining the efficacy of therapy in the treatment of amyloidosis involves administering to a patient in need thereof a compound of formula (I) or Formula (II) or structures 1-45 and imaging the patient. After said imaging, at least one anti-amyloid agent is administered to said patient. Then, an effective amount of a compound of formula (I) or Formula (II) or structures 1-45 is administered to the patient and the patient is imaged again. Finally, baseline levels of amyloid deposition in the patient before treatment with the anti-amyloid agent are compared with levels of amyloid deposition in the patient following treatment with the anti-amyloid agent.

  • Patent number: 8138360
    Abstract: Benzofuran compounds which contain at least one detectable label selected from the group consisting of 131I, 123I, 124I, 125I, 76Br, 75Br, 18F, 19F, 11C, 13C, 14C and 3H are provided as amyloid imaging agents for detecting brain amyloid deposits as well as other amyloidogenic peptides associated with systemic or localized amyloidosis. Additionally, the compounds are useful for determining if patients, presenting with clinically confusing cases of dementia or presenting with mild cognitive impairment, have Alzheimer's disease. The compounds are additionally useful as surrogate markers for monitoring the efficacy of anti-amyloidosis therapies.

  • Publication number: 20080286202
    Abstract: A method of identifying a patient as prodromal to a disease associated with amyloid deposition by imaging techniques is provided. In addition, a method of identifying amyloid deposition diseases in patients who present with a dementing disorder of questionable etiology by imaging techniques is provided. The methods discloses substances which are used for imaging and generating data which can be used to determine progress of an asymptomatic patient to a disease associated with amyloid deposition, or to identify amyloid deposition diseases in patients who present with a dementing disorder of questionable etiology.
