April 24, 2026 updated by: AbbVie

A Phase 1 Pharmacokinetic Study in Healthy Adult Volunteers to Evaluate the Bioavailability of ABBV-8736 Following Subcutaneous Administration Relative to Intravenous Administration

The purpose of this study is to assess the pharmacokinetics (PK), bioavailability, immunogenicity, safety, and tolerability of ABBV-8736 following subcutaneous (SC) administration relative to intravenous (IV) administration.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Body mass index (BMI) is >= 18.0 to <= 32.0 kg/m2 after rounding to the tenths decimal. BMI is calculated as weight in kg divided by the square of height measured in meters.
  • Body weight >= 35 kg.
  • A condition of general good health, based upon the results of a medical history, physical examination, vital signs, laboratory profile and a 12-lead electrocardiogram (ECG).

Exclusion Criteria:

  • Participant requires any over-the-counter and/or prescription medication, vitamins, and/or herbal supplements, on a regular basis.
  • Participant uses any medications, vitamins and/or herbal supplements within the 14-day period prior to study treatment administration.
  • Participant has received any treatment by injection within 30 days or within a period defined by 5 half-lives, whichever is longer, prior to study treatment administration.
  • Participant has prior exposure to a Triggering Receptor Expressed on Myeloid Cells 1 (TREM1) agent.
