UKK-0018 as an Immunotherapeutic for Treatment of Peanut Allergies (UKK-0018)

June 22, 2026 updated by: Ukko Inc

A First-in-Human, Ascending Dose, Open-label, Multicenter Study to Evaluate the Safety, Tolerability and Preliminary Efficacy of UKK-0018 in Peanut Allergic Individuals

This study will test a new investigational treatment called UKK-0018. UKK-0018 as an immunotherapeutic for the treatment of peanut allergies. The treatment is given by injection and is designed to train the immune system to tolerate peanut exposure over time.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will assess how safe and well tolerated UKK-0018 is in people with known peanut allergy, and whether it can reduce the risk of allergic symptoms following exposure to peanut proteins.

This is a first-in-human, open-label, multicenter study that will be conducted in adult participants with peanut allergy evaluating dose levels and regimens. It is anticipated that UKK-0018 can help retrain the immune system over time to respond safely to peanut proteins in case of accidental exposures. The modifications which reduce binding to IgE antibodies are anticipated to reduce risk of serious allergic reactions compared to standard of care.

Based on emerging data an optional dose expansion cohort may be added. An optional dose expansion cohort may be added if supported by emerging data. The study is comprised of a screening period, intervention period, and follow-up period.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
