Pegloticase and Methotrexate Cotherapy in Patients With Uncontrolled Gout With Prior Pegloticase Monotherapy Failure: Findings of an Open-Label Trial.

Objective: Patients with uncontrolled gout have few treatment options. Pegloticase lowers serum urate (SU) levels, but antidrug antibodies limit SU-lowering response and increase infusion reaction (IR) risk. Methotrexate (MTX) cotherapy increases pegloticase response rates and lowers IR risk in pegloticase-naïve patients.

Pharmacokinetics of Fipaxalparant, a Small-Molecule Selective Negative Allosteric Modulator of Lysophosphatidic Acid Receptor 1, and the Effect of Food in Healthy Volunteers.

Dysregulated lysophosphatidic acid receptor 1 (LPAR1) signaling is implicated in fibrotic diseases, including systemic sclerosis (SSc) and idiopathic pulmonary fibrosis (IPF). Fipaxalparant (HZN-825) is a small molecule acting as a negative allosteric modulator of LPAR1 and is in phase 2 clinical evaluations for treating diffuse cutaneous SSc and IPF. This open-label, phase 1 study examined the pharmacokinetics (PKs), food effect, and safety of fipaxalparant in healthy volunteers.
