The disclosure provides methods of treating gout in patients comprising administering a PEGylated uricase. Also provided are methods of treating gout in patients comprising co-administering a PEGylated uricase and MMF. Also provided are methods of reducing intolerance to a PEGylated uricase and prolonging the urate lowering effect comprising co-administration of the PEGylated uricase and MMF.

Genetically modified proteins with uricolytic activity are described. Proteins comprising truncated urate oxidases and methods for producing them, including PEGylated proteins comprising truncated urate oxidase are described.

Methods and kits for predicting infusion reaction risk and antibody-mediated loss of response during intravenous PEGylated uricase therapy in gout patients is provided. Routine SUA monitoring can be used to identify patients receiving PEGylated uricase who may no longer benefit from treatment and who are at greater risk for infusion reactions.

The present disclosure relates to erythroid cells that have been engineered to comprise a uricase, a uric acid transporter, or both a uricase and a uric acid transporter. The engineered erythroid cells of the present disclosure are useful in degrading uric acid inside the engineered erythroid cell. The engineered erythroid cells of the present disclosure are useful in methods of treating hyperuricemia. The engineered erythroid cells of the present disclosure are also useful in methods of treating gout, and in particular chronic refractory gout.

The present disclosure is directed to the use of a uric acid lowering agent (UALA) to increase the effectiveness of interferon in a subject with a viral infection. The UALA may be administered in combination with interferon in a subject undergoing interferon therapy.

The present invention discloses methods to prevent gout flares using IL-1? inhibitors. A method of treating gout patients using methotrexate, canakinumab, and pegloticase is described.

Methods and kits for predicting infusion reaction risk and antibody-mediated loss of response during intravenous PEGylated uricase therapy in gout patients is provided. Routine SUA monitoring can be used to identify patients receiving PEGylated uricase who may no longer benefit from treatment and who are at greater risk for infusion reactions.

Provided herein are pharmaceutical compositions including a URAT1 inhibitor and methods of use thereof. The pharmaceutical compositions can include dotinurad, a xanthine oxidase inhibitor, such as allopurinol and/or a sodium-glucose cotransporter-2 inhibitor. The pharmaceutical compositions described herein can be used for the treatment of diseases and conditions related to uric acid, including chronic kidney disease.

A recombinant nucleic acid molecule for making a circular RNA and a preparation method for the circular RNA are provided. The recombinant nucleic acid molecule comprises elements operably linked to each other and arranged, in a 5 to 3 direction, in the following order: (a) an intron fragment which includes a full-length intron; (b) an E2 fragment which includes a downstream exon of the full-length intron; (c) an internal ribosome entry site (IRES) fragment; (d) a urate oxidase coding fragment; and (e) an E1 fragment which includes an upstream exon of the full-length intron; wherein the full-length intron, the downstream exon, and the upstream exon are from a same gene.
