Brief summary

Detailed description
This is a randomized, placebo controlled, double-blind, 2-way crossover study to assess the effect of intensive UA lowering therapy with verinurad (RDEA3170), febuxostat, and dapagliflozin on urinary excretion of UA, in asymptomatic hyperuricemic patients. Thirty-six asymptomatic hyperuricemic patients aged 18 to 65 years (inclusive) will be enrolled into this study at 2 study centers. Twenty-four patients have been enrolled and completed the study to date. Due to inadequate urine sampling, 12 additional patients were included to ensure an adequate sample size (at least 20 evaluable patients) to evaluate the effects of intensive UA lowering with verinurad, febuxostat and dapagliflozin on urinary excretion of UA. With 24 completers available during the interim analysis, this will provide for a total sample size of 36 evaluable patients. Before any study specific assessments are performed, potential patients must provide informed consent. Each patient will undergo the below mentioned visits: * A Screening period of maximum 28 days; * Two treatment periods during which patients will be resident in the Clinical Unit from Day -2 to Day 1 and from Day 6 to Day 8; and * A Follow-up Visit within 14 to 28 days after the first administration of Investigational Medicinal Product (IMP) in Treatment Period 2. On Day -2 of Treatment period 1, patient will be randomized (1:1) to 1 of 2 treatment sequences (AB or BA). Each randomized patient will receive orally once daily fixed dose of the below mentioned 2 treatments for 7 consecutive days (1 treatment per treatment period). * Treatment A: Verinurad + febuxostat + dapagliflozin * Treatment B: Verinurad + febuxostat + placebo For each treatment period, baseline measurements will be performed. On Day 1, after all dosing and all assessments have been performed, patients will receive instruction to administer the IMP at home once daily in the morning from Day 2 to Day 6 and the IMP will be dispensed for home dosing. Patients will return to the Clinical Unit on Day 6 and will be residential in the Clinical Unit from Day 6 to Day 8. Treatment Period 1 and Treatment Period 2 will be separated by a washout period of 7 to 21 days. Patients will return to the Clinical Unit for a Follow-up Visit, 14 to 28 days after Day 1 of Treatment Period 2.

Study design
Masking description
The pharmacokineticist will remain blinded during the study conduct, unless otherwise required based on study findings. The pharmacokineticist will be unblinded to perform the final PK analyses after all patients have completed the study, final bioanalytical results are available and all required study data are considered clean. This may occur before database lock.
