Single- and multiple-dose testing of AKB-9090 in healthy adults

A Randomized, Double-Blind, Placebo-Controlled, Single (SAD) and Multiple Ascending-Dose (MAD) Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AKB-9090 Administered Intravenously to Healthy Adult Participants

Phase 1 Interventional Akebia Therapeutics · NCT07429006

This will test whether single and multiple doses of AKB-9090 are safe and how the body processes the drug in healthy adults.

What this trial studies

This first-in-human, phase 1 single-centre study will enroll about 40 participants in a single ascending dose (SAD) phase across five cohorts and about 30 participants in a multiple ascending dose (MAD) phase across three cohorts. Participants will receive AKB-9090 or placebo with safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) measurements collected during confinement and subsequent outpatient visits. Dosing begins at a low level and is escalated between cohorts with safety reviews guiding dose increases. The study aims to define dose-related effects and PK/PD profiles in healthy adults to inform later patient-focused trials.

Who should consider this trial

Good fit: Healthy adults with BMI 18.5–32.0 kg/m2, no clinically significant medical findings on screening tests, and willing to comply with confinement and study visit requirements are ideal candidates.

Not a fit: People with significant medical conditions, abnormal screening tests, or who cannot comply with study confinement and visit schedules are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, the study could identify safe dose ranges and PK/PD characteristics to support further clinical development of AKB-9090.

How similar studies have performed: This is the first-in-human trial for AKB-9090, though SAD and MAD designs are standard and have successfully guided dose selection for many other investigational drugs.

Eligibility criteria

Show full inclusion / exclusion criteria
Key Inclusion Criteria:

* Healthy adult participants with no clinically significant findings, as judged by the investigator, based on physical examination, 12-lead ECG, alcohol breath test, and clinical laboratory tests (including serum chemistry, hematology, coagulation, urine drug screen, and urinalysis).
* Body mass index (BMI) greater than 18.5 and less than 32.0 kg/m\^2 at screening.
* In the Investigator's opinion, willing and able to provide written informed consent and comply with the all protocol requirements, including required confinement, outpatient visits, and protocol-specified restrictions (including refraining from major lifestyle changes) from signature of the informed consent form (ICF) through the last study visit.

Key Exclusion Criteria:

* Clinically significant metabolic, hepatic, renal, hematologic, pulmonary, cardiovascular, gastrointestinal, musculoskeletal, dermatologic, urogenital, ophthalmologic, ear/nose/throat, psychiatric, or neurologic disorder.
* History of active or recurrent malignancy within 2 years before screening or during the screening period, or currently receiving treatment or suppressive therapy for cancer, except for:

  1. Treated basal cell carcinoma of the skin
  2. Curatively resected squamous cell carcinoma of the skin
  3. Treated colonic or cervical carcinoma in situ
* Abnormal ECG findings at screening, including:

  1. Severe bradycardia (heart rate \<40 beats per minute) on any measurement
  2. Mean QT Interval Using Fridericia's Formula (QTcF) \>450 msec for males or \>470 msec for females
* Elevated laboratory values (\>1.25 × upper limit of normal \[ULN\]) for alanine aminotransferase (ALT), aspartate aminotransferase (AST), or creatinine at the screening visit or at check-in.
* Evidence of acute or chronic hepatitis B (positive hepatitis B surface antigen) or hepatitis C infection (positive hepatitis C antibody and positive hepatitis C ribonucleic acid \[RNA\] test).
* Use of nicotine-containing products (including cigarettes, cigars, tobacco, gum, patches, vaping, and e-cigarettes), caffeine-containing foods or beverages, and alcohol-containing foods or beverages during study.
