A Phase 1 interventional study of ALLN-346 and Placebo in Hyperuricemia, sponsored by Allena Pharmaceuticals. Completed at 1 site in United States. Open to participants aged 18 Years to 55 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-07-23.
Sponsored by Allena Pharmaceuticals · Phase 1, Interventional, and Treatment
The purpose of this study is to evaluate the safety of ALLN-346 in healthy volunteers, in this first in human, single ascending dose study. ALLN-346 is an enzyme that degrades urate in the gastrointestinal tract.
This is a Phase I, randomized, double-blind, placebo-controlled single ascending dose study of orally administered ALLN-346. The study will evaluate the safety and tolerability, inflammation and immunogenicity, pharmacokinetics and pharmacodynamics of ALLN-346 in healthy volunteers. The study consists of a Screening Period, a Treatment Period of 3 days, which includes 1 single day of dosing and 3 days of in-house observation, and a safety Follow-up Period through Day 28 following dosing.
240 studies on the registry are indexed under Hyperuricemia; 44 are open to participants now.
This study's enrollment of 24 is below the median of 68 across 193 interventional studies indexed under Hyperuricemia.

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.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
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.
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.
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.
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.
