A Phase 2 interventional study of ALLN-346 and Placebo in Hyperuricemia, Gout and Chronic Kidney Diseases, sponsored by Allena Pharmaceuticals. Completed at 1 site in United States. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2023-06-22.
Sponsored by Allena Pharmaceuticals · Phase 2, Interventional, and Treatment
The purpose of this Phase IIa study is to evaluate the safety and tolerability of ALLN-346 in subjects with hyperuricemia in an inpatient, controlled setting.
This is a Phase II, 7-day, randomized, double-blind, placebo-controlled study of orally administered ALLN-346 in subjects with hyperuricemia, with subpopulations to include generally healthy hyperuricemic subjects with normal kidney function and those with mild to moderate chronic kidney disease (CKD). Study will take place at a clinical pharmacology unit (CPU). The study will have two Parts. Part 1 will include subjects with serum urate ≥ 6.8 mg/dL and eGFR ≥ 60 mL/minute/1.73 m2 (subjects with eGFR of stage 2 CKD and with normal kidney function). Part 2 will include subjects with serum urate ≥ 6.8 mg/dL and eGFR 45-100 mL/minute/1.73 m2 (eGFR of CKD Stages 2- 3a).
The study will evaluate safety, tolerability, pharmacokinetics (lack of absorption) and pharmacodynamics of ALLN-346.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
