Dose Finding Study to Evaluate Safety and Efficacy of 3 Dosages of SAP 001.
United States, Puerto Rico87 participantsStarted 2022-12-12
Plain-language summary
The aim of this study is to confirm the safety and pharmacological characteristics of SAP-001, evaluate its efficacy in lowering sUA and tophus burden, and identify the appropriate dose regimen for future studies in adult subjects with gout, with or without tophi, and hyperuricemia refractory to SoC XOI therapy.

Inclusion criteria
. Male or female, ≥18 and ≤75 years of age, willing and able to provide informed consent and to adhere to the requirements and guidelines of the protocol.
. Body mass index ≥19 and ≤40 kg/m2 at the Screening Visit (Visit 1).
. Already have been diagnosed with gout according to the current American College of Rheumatology (ACR) scoring criteria for the classification of primary gout; or has symptoms of gout with at least 1 of the following: i. 3 gout flares in the previous 18 months prior to screening; or ii. Presence of at least 1 gout tophus; or iii. Current diagnosis of gouty arthritis; Subject must be refractory to SoC XOI therapy, or in whom XOI is contraindicated. Refractory to SOC XOI is defined by a medical history of failure to normalize sUA to \<6 mg/dL (the ACR target for gout) with at least 3 months of SoC XOI treatment at the maximum medically appropriate dose. XOI contraindication can be self-reported medical contraindication to SoC XOI therapy or in whom SoC XOI therapy is not considered medically appropriate treatment for symptomatic gout. Subject can still participate in the clinical trial if SOC XOI therapy is considered medically not appropriate or contraindicated.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

. Subject must have been on SoC XOI therapy for gout and hyperuricemia for at least 4 weeks immediately before the Randomization Visit (Day 1, Visit 4) unless SoC XOI therapy is contraindicated or not medically appropriate. Subjects who stopped SoC XOI therapy within 4 weeks of the Screening Visit are eligible for the study but must be restarted on SoC XOI therapy and confirmed resistant to XOI therapy (sUA levels ≥7.0 mg/dL) after at least 4 weeks of treatment.
. Subject must have sUA levels ≥7.0 mg/dL by central laboratory results at the Screening Visit (Visit 1) and prior to randomization at the Randomization Visit (Day 1, Visit 4).
Exclusion criteria
. Subjects not previously diagnosed as having gout before the Screening Visit.
. Female subject is pregnant, planning to get pregnant, lactating/breastfeeding, or has a positive urine pregnancy test at the Screening Visit or prior to randomization at the Randomization Visit (Day 1, Visit 4).
. Subject has used any prescription drugs (eg, losartan, pegloticase, URAT1 inhibitors), OTC medications, herbal medications or products, vitamins, or minerals that are known to lower sUA levels (except SoC XOI therapies) within 14 days prior to the Randomization Visit (Day 1, Visit 4). Exceptions may be made on a case-by-case basis (such as chronic use of low dose aspirin) following discussion and agreement between the investigator and sponsor. Subjects who are already taking losartan for blood-pressure control are allowed to enroll in the study and continue taking losartan if they have been on a stable dose for at least 6 months.
. Subject was not compliant with taking placebo during the Run-in Period (defined as taking \<80% or \>120% of planned placebo doses) or the investigator determines that the subject was not compliant with SoC XOI gout medications (unless SoC XOI therapy is contraindicated or not medically appropriate) during the Run-in Period as assessed prior to randomization at the Randomization Visit (Day 1, Visit 4).
. Subject had an acute gout flare (exclusive of symptomology associated with chronic synovitis/arthritis) that did not resolve at least 14 days prior to the Randomization Visit (Day 1, Visit 4). If an acute gout flare occurs during the Screening or Run-in Periods, the subject may be rescreened after a period of at least 14 days has passed following resolution of the flare.
. Serum creatinine level \>1.5 mg/dL and/or eGFR ≤60 mL/min/1.73 m2 calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation23 by central laboratory results at the Screening Visit (Visit 1) or prior to randomization at the Randomization Visit (Day 1, Visit 4).
