What is this trial about?

A plain-language summary of the goals, design and what participants do

This study involves no specific disease; it is conducted in healthy volunteers to examine how the body handles a single oral dose of the investigational drug RO7268489, which is provided as a liquid solution taken by mouth. The aim of the study is to assess the drug’s pharmacokinetics—that is, how it is absorbed, distributed, broken down, and removed—and to determine whether eating a meal changes these processes.

Participants will receive one dose of the medication on two separate occasions. The first dose is taken after an overnight fast, and the second dose is taken after a standard meal. After each dose, blood samples are collected over several hours to measure the total drug exposure, described as the AUC, and the highest concentration reached in the blood, called the Cmax. Safety is monitored throughout the study by checking for any unwanted side effects, referred to as adverse events, as well as routine laboratory tests, vital signs, and a simple heart rhythm test (ECG).

The research process

The trial runs in 5 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial visit and screening

    You arrive at the clinic after you have agreed to take part in the study.

    Staff will check your health with a physical exam, basic laboratory tests, and a brief heart rhythm test called an ecg to make sure you are healthy enough for the study.

  2. Step 2

    First dosing period (fasted)

    You will fast, meaning no food or drink except water, for at least ten hours before the visit.

    On the morning of the visit you will receive a single 1 mg dose of ro7268489 taken as an oral solution.

    After taking the medicine a series of blood samples will be drawn at scheduled times to measure how the medicine moves through your body.

    You will stay at the clinic for several hours while the samples are collected and you will be monitored for any side effects.

  3. Step 3

    Washout period

    After the first dosing day you will have a break of several days with no further doses of the study medicine to allow your body to clear the drug.

    During this time you may continue normal activities but should avoid taking other investigational medicines.

  4. Step 4

    Second dosing period (fed)

    You will eat a standard meal provided by the clinic.

    Shortly after finishing the meal you will receive another single 1 mg dose of ro7268489 as an oral solution.

    blood samples will again be taken at the same scheduled times as in the first period to compare the effect of food on the medicine.

    You will remain at the clinic for observation and monitoring for side effects.

  5. Step 5

    Final assessments and study completion

    After the second dosing day the staff will perform a final check of vital signs, repeat laboratory tests, and an ecg to ensure everything is normal.

    You will receive information about the overall study timeline and any follow‑up that may be needed.

    The study will then be considered complete for you.

Who can join the trial?

  • You must be a man or a woman who is healthy (no known illnesses or medical problems).
  • Your body mass index (BMI) must be between 18 and 30 kg/m². BMI is a calculation that uses your height and weight to show if you are underweight, normal weight, or overweight.

  • Your laboratory test results (including a complete blood count, chemistry panel, or urine test) show significant problems.
  • You have a history of serious hypersensitivity (allergic) reactions.
  • You have an active or uncontrolled infection (bacterial, viral, fungal, or mycobacterial such as tuberculosis), or you have had COVID‑19 symptoms or any flu or COVID‑19 vaccination within the past 6 weeks.

Investigated drugs

RO7268489 is an experimental medicine being tested for the first time in people. In this study participants take a single dose as a liquid you swallow. The researchers are looking at how the drug moves into the blood after it is taken, and whether the timing of the dose or eating food changes how much of the medicine gets into the bloodstream. This helps them understand how the drug works and what conditions are needed for it to be safe and effective in the future.

What is already known about the treatment

RO7268489 - RO7268489 is taken as a 1 mg oral solution that participants swallow. It is an experimental small‑molecule drug that has not been approved and is only mentioned in early clinical trial reports. The trial is studying its safety and how it moves through the body, with no specific disease treatment assigned yet. It works by binding to a particular protein in the body to change its activity, placing it in the class of investigational oral targeted therapies.
