Safety/Efficacy Study to Evaluate of MBX-102 in Combination With Allopurinol in Gout Patients

Completed · Phase 2 · Has a placebo group

Conditions studied: Gout

In brief

The purpose of this study is to evaluate the efficacy, safety and tolerability of MBX-102 in combination with allopurinol compared to allopurinol alone when administered orally once a day for four weeks to gout patients with an inadequate hypouricemic response to allopurinol alone.

• OR -
• Patients who are not on ULT or are taking allopurinol < 200 mg/day must have a sUA ≥ 8.0 mg/dL and ≤ 12 mg/dL at screening and ≥ 6.0 mg/dL and ≤ 12 mg/dL at Week -1 (Visit 2) randomization visit.
• Male or female, 18-75 years of age at screening
• All female patients must be surgically sterile or post-menopausal (at least 45 years of age with no history of menses for at least 2 years; or any age with no history of menses for at least six months and serum FSH ≥ 40 mIU/mL) or have a partner who has undergone vasectomy or must agree to use two medically accepted methods of contraception including a barrier method (see the list in Appendix 4) for the entire duration of the study unless she reports complete sexual abstinence.
• Female patients must not be pregnant or lactating.

• Estimated creatinine clearance (CrCl) by Cockcroft-Gault method ≥ 60 mL/min at screening
• Serum creatinine value ≤ 1.1 mg/dL in females and ≤ 1.3 mg/dL in males
• Liver function tests ≤ 1.5X ULN for AST, ALT and T-bilirubin, ≤ 2X ULN for ALP, ≤ 3X ULN for GGT; and ≤ 3X ULN for CK
• All other clinical laboratory parameters must be within normal limits or considered not clinically significant for participation in this study.
• Electrocardiogram (ECG) must be normal, or if abnormal, considered not clinically significant for participation in this study.
• Systolic blood pressure ≤ 160 mm Hg and diastolic blood pressure ≤ 90 mm Hg; known hypertensive patients controlled with medications other than thiazide diuretics (blood pressure [BP] reading as above) may be included

You may not qualify if…

• Chronic treatment with NSAIDs (use to treat acute flares are permitted).
• Current or expected treatment with systemic corticosteroids (except topical, ophthalmic, intra-articular, or inhaled at a dose < 1600 μg/day) other than to treat acute flare
• Known hypersensitivity to allopurinol, colchicine, or aspirin
• Treatment with any other investigational therapy within the 30 days prior to screening, or patients who received at least one dose of study drug while enrolled in any previous or concomitant MBX-102 trial
• Any other condition that compromises the ability of the patient to provide informed consent or to comply with the objectives and procedures of this protocol, as judged by the investigator and/or medical monitor.
