Plain English Summary

Background and study aims
Inflammatory bowel disease (IBD) is a health condition that makes parts of the digestive system, like the stomach and intestines, become swollen. This can cause problems like tummy pain, loose stools, and, sometimes, bleeding. This study is testing a medicine called RO7504109. It is being developed as a possible treatment for IBD. RO7504109 is an experimental medicine. This means health authorities (like the U.S. Food and Drug Administration, European Medicines Agency, or Medsafe) have not approved RO7504109 for the treatment of any disease. This study aims to test the safety of RO7504109 after both single and multiple doses, what happens to RO7504109 once it is in the body, and what RO7504109 does to the body.

Who can participate?
Healthy people (males and females) of 18-65 years of age with a body weight of at least 50 kilograms (kg) can take part in the study.

People who are pregnant, or currently breastfeeding cannot take part in the study.

What does the study involve?
People will be screened to check if they can participate in the study. The screening period will take place 28 days to 1 day before the start of the treatment.

Everyone who joins this study will receive RO7504109 given either as an injection under the skin or an infusion into the vein. Participants in Group 1 will receive a single dose of RO7504109 or placebo on Day 1, whereas participants in Group 2 will receive a total of 5 doses of RO7504109 or placebo with dosing every 2 weeks (Q2W). Placebo is a substance that contains no active ingredients but looks the same as the study drug. This means that it does not have any direct effects on the body. Participants will have regular blood tests and will be checked for unwanted effects throughout the study.
This is a double-blind study. A double-blind study is a study where nobody knows which treatment is being given – neither the people in the study nor the team running it. This is done to make sure that the results of the treatment are not affected by what people expect from the received treatment. However, the study doctor can find out which group the participant is in, if the participant’s safety is at risk. During the study, the doctor will see participants during the overnight stays at the clinic for up to 2 nights after the treatment is given. Participants will have multiple follow-up visits after completing the study treatment, and a phone call on Day 10, during which the study doctor will check on the participant’s well-being. The total time of participation in the study will be about 26 weeks for Group 1 and about 34 weeks for Group 2. Participants have the right to stop study treatment and leave the study at any time if they wish to do so.

What are the possible benefits and risks of participating?
RO7504109 is an experimental drug and is being given purely for research purposes, it is not intended that participants will receive any benefit from this study. However, the information collected in the study can help people with diseases in the future.

RO7504109 RO7504109 is currently being tested in humans, and few side effects of this drug are not known at this time. The study involves some risks to the participants. People interested in taking part will be informed about the risks, as well as any additional procedures or tests they may need to undergo. All details of the study will be described in an informed consent document. This includes information about possible risks from the treatment.

Risks associated with the study drug

Participants may have unwanted effects of the drug used in this study. These unwanted effects can be mild to severe, or life-threatening and can vary from person to person. However, adequate safety measures will be in place to reduce the risk of severe unwanted effects happening. During this study, participants will have regular check-ups to see if there are any unwanted effects.

RO7504109:
RO7504109 is currently being tested in humans. Not all the unwanted effects of this medicine are known at this time. Participants will be told about the possible unwanted effects based on laboratory studies or knowledge of similar medicines. Known unwanted effects include low blood pressure, headache, and/or vomiting. Study medicine will be given as an injection or as an infusion, and the known unwanted effects are injection site pain and/or rash. The study medicine(s) may be harmful to an unborn baby. Women and men must take precautions to avoid exposing an unborn baby to the study treatment.
