1.Subject is an adult male or non-reproductive (post-menopausal or surgically sterile) female. Postmenopausal is generally defined as a period of twelve (12) consecutive months of amenorrhoea. In women under 55 years of age whose menopausal status is in question, a follicle-stimulating hormone (FSH) level of >40 mIU/mL or an oestrogen deficiency of < 30 pg/m or a negative oestrogen test can confirm they are postmenopausal.
2.Subject is = 18 and = 80 years of age at the time of day 1 study drug dosing
3.Subject has a body mass index (BMI) = 18 and = 38 kg/m2, and weighs at least 50 kg (110 lbs)
4.Subject meets one or more of the 1977 American Rheumatism Association (ARA) criteria for the diagnosis of acute arthritis of primary gout
5.Subject has moderate renal impairment with an estimated creatinine clearance as determined by the Modification of Diet in Renal Disease (MDRD) method at screening that is = 30 mL/min to < 60 mL/min. [Creatinine clearance determined MDRD method: CrCl (mL/min/1.73 m2) = 175 x (serum creatinine)-1.154 × (age)-0.203 x [1.212 if Black] x [0.742 if female]]. Subjects with age-related renal impairment may be included in addition to those with underlying renal disease.
6.Subject has a screening serum urate (sUA) level = 7 mg/dL for Cohort 1 and = 6 mg/dL for Cohort 2, unless a lower sUA is agreed to by the Sponsor’s Medical Monitor.
7.For Cohort 1, subject is not receiving urate lowering therapy for at least one month prior to the screening visit. For Cohort 2, subject is receiving a stable dose of allopurinol of 100 to 200 mg once daily for at least one month prior to the screening visit and dosage should remain unchanged for the duration of the study.
8.Subject has a clinically acceptable physical examination with respect to the subject’s degree of renal impairment.
9.Subject is free of any clinically significant disease that would interfere with study evaluations or procedures.
10.Subject is informed of the nature of the study and has agreed to and is able to read, review and sign the informed consent document prior to any study related activities.

1. Subject requires dialysis for treatment of renal disease.
2.Subject has a gout flare at screening that is resolved for less than one week prior to the first administration of study drug (exclusive of chronic synovitis/arthritis).
3.Subject has documented history of, or suspicion of kidney stones.
4.Subject has received any investigational drug within 2 months prior to study drug dosing.
5.Subject has received a strong or moderate inhibitor of CYP3A4 or a P-gp inhibitor within 1 month prior to study drug dosing due to potential interactions with colchicine.
6.Subject reports receiving any enzyme-inducing drug or product within 2 months prior to study drug dosing.
7.Subject has uncontrolled hypertension, a clinically relevant abnormality in blood pressure (BP), heart rate (HR), body temperature, or respiratory rate as per the Investigator’s judgment as follows:
a.Systolic BP < 90 mmHg and > 190 mmHg in supine position
b.Diastolic BP < 45 mmHg and > 110 mmHg in supine position
c.Heart rate < 40 bpm and > 100 bpm in supine position
d.Body temperature < 35.0°C and > 37.5°C
e.Respiratory rate < 8 bpm and > 20 bpm
8.Subject has used medications that prolong the QT/QTc interval within 14 days prior to Day 1 dosing
9.Subject has a history of clinically significant health problems or diseases unrelated to the patient’s renal insufficiency as determined by the clinical investigator(s). Patients with disorders related to renal insufficiency may be enrolled if in the investigator’s judgment the disorder will not compromise patient safety or study objectives
10.Subject has a serum ALT or AST that exceeds 2.5 times the upper limit of normal.
11.Subject has presence or history of cardiac abnormalities including abnormal and clinically relevant ECG changes such as bradycardia (sinus rate < 40 bpm), complete Left Bundle Branch Block (LBBB), second or third degree heart block, intraventricular conduction delay with QRS duration >140 milliseconds (msec), symptomatic arrhythmias, heart failure, hypokalemia, family history of Long QT Syndrome, family history of sudden death in otherwise healthy individual between the ages of 1 and 30 years
12.Subject has a QTcB interval (QT interval corrected for heart rate according to Bazett) > 470 msec for males and > 490 msec for females at Screening, on Day –1 or pre-dose on Day 1.
13.Subject has undergone major surgery within 3 months of Day 1.
14.Subject has a confirmed reactive screen for hepatitis B surface antigen, hepatitis C antibody, or HIV antibody. Positive hepatitis C antibody to be confirmed by PCR.
15.Subject has uncontrolled Diabetes Mellitus, metabolic syndrome, or chronic diarrhea.
16.Subject has a clinically significant illness during the 7 days prior to day 1 study drug dosing (as determined by the clinical investigator)
17.Subject demonstrates a positive drug screen (cocaine, cannabis, amphetamine, opiate) or alcohol screen at screening or check-in (Day -1), with the exception of prescription drugs
18.Subject has a known hypersensitivity or allergy to RDEA594, allopurinol, colchicine, or any components in their formulations
19.Subject has a history of clinically significant allergies including food or drug allergies
20.Subject reports a history (within the past 12 months) or presence of drug addiction or excessive use of alcohol (weekly intake in excess of 28 units of alcohol; one unit of alcohol equals ½ a pint of beer or lager, a glass of wine or a measure of spirits)
21.Subject has donat
