Abstract

Disclosed herein is method for conjugating a metal chelating agent to a functionalized dextran by reacting a chelator with an aminated dextran backbone, where the chelator comprises a one, and only one, derivatized carboxylic acid group to form a chelator-dextran complex. In certain aspects, the dextran-chelator complex is substantially free of intra- or intermolecular crosslinking. In certain aspects, the functionalized dextran is an amine dextran, an alkynyl dextran, or a thiol dextran. In exemplary implementations, the functionalized dextran is an amine dextran. In further embodiments, one and only one carboxylic acid group on the chelating agent is derivatized as a N-hydroxysuccinimide (NHS) ester.

Abstract

Disclosed herein are methods of treating a subject with rheumatoid arthritis (RA) and methods of predicting the subject's likelihood of responding to a new RA therapy. The methods include administering to the subject a composition comprising a macrophage targeting construct and an imaging moiety conjugated thereto to acquiring planar images of a plurality of joints of the subject, and determining at least one TUVGlobal value for the subject from the planar images. Covariates comprising the quantification of serological RA markers and/or clinical assessments may be further obtained to apply statistical modeling to the combination of the at least one TUVGlobal and the one or more covariates. The statistical modeling is used to determine a likelihood of response to an RA therapy, and a treatment is administered to the subject based on the likelihood of response to the RA therapy.

Abstract

Disclosed herein are methods of treating a subject with rheumatoid arthritis (RA) and methods of predicting the subject's likelihood of responding to a new RA therapy. The methods include administering to the subject a composition comprising a macrophage targeting construct and an imaging moiety conjugated thereto to acquiring planar images of a plurality of joints of the subject, and determining at least one TUV Global value for the subject from the planar images. Covariates comprising the quantification of serological RA markers and/or clinical assessments may be further obtained to apply statistical modeling to the combination of the at least one TUV Global and the one or more covariates. The statistical modeling is used to determine a likelihood of response to an RA therapy, and a treatment is administered to the subject based on the likelihood of response to the RA therapy.

Abstract

Disclosed herein is method for conjugating a metal chelating agent to a functionalized dextran by reacting a chelator with an aminated dextran backbone, where the chelator comprises a one, and only one, derivatized carboxylic acid group to form a chelator-dextran complex. In certain aspects, the dextran-chelator complex is substantially free of intra- or intermolecular crosslinking. In certain aspects, the functionalized dextran is an amine dextran, an alkynyl dextran, or a thiol dextran. In exemplary implementations, the functionalized dextran is an amine dextran. In further embodiments, one and only one carboxylic acid group on the chelating agent is derivatized as a N-hydroxysuccinimide (NHS) ester.

Abstract

Disclosed herein are methods of treating a subject with rheumatoid arthritis (RA) and methods of predicting the subject's likelihood of responding to a new RA therapy. The methods include administering to the subject a composition comprising a macrophage targeting construct and an imaging moiety conjugated thereto to acquiring planar images of a plurality of joints of the subject, and determining at least one TUV Global value for the subject from the planar images. Covariates comprising the quantification of serological RA markers and/or clinical assessments may be further obtained to apply statistical modeling to the combination of the at least one TUV Global and the one or more covariates. The statistical modeling is used to determine a likelihood of response to an RA therapy, and a treatment is administered to the subject based on the likelihood of response to the RA therapy.

Abstract

Disclosed herein is method for conjugating a metal chelating agent to a functionalized dextran by reacting a chelator with an aminated dextran backbone, where the chelator comprises a one, and only one, derivatized carboxylic acid group to form a chelator-dextran complex. In certain aspects, the dextran-chelator complex is substantially free of intra- or intermolecular crosslinking. In certain aspects, the functionalized dextran is an amine dextran, an alkynyl dextran, or a thiol dextran. In exemplary implementations, the functionalized dextran is an amine dextran. In further embodiments, one and only one carboxylic acid group on the chelating agent is derivatized as a N-hydroxysuccinimide (NHS) ester.
