About this study

Official title: Single Ascending Dose Study to Assess the Safety, Tolerability, Pharmacokinetic, and Pharmacodynamic Effects of SR-878 in Healthy Volunteers

SR-878 is a newly developed medicine that aims to treat autoimmune disorders. It inhibits a protein (iRhom2), that regulates enzymes that are involved in the production of cytokines (small proteins that are crucial in controlling the activity of immune system cells). This is the first study in humans, and SR-878 will be administered once to each participant in 6 different doses to establish a safe dosage and investigate, what are potential side effects.

This clinical trial includes six study groups, called cohorts, and each cohort includes 8 participants. In each cohort, 6 participants will receive SR-878 and 2 participants will receive a placebo, a dummy drug with no active ingredients that looks identical. The comparison with placebo will be used to better assess the side effects of SR-878. The dose of SR-878 will be gradually increased between cohorts. Participants in the first cohort will receive the lowest dose, and if this is considered safe 10 days after dosing, the next cohort will be initiated at a higher dose. Participants visit the hospital regularly over the next 12 weeks after receiving SR-878 or placebo. During these visits, medical condition will be checked and blood will be taken.

Participants in the third to sixth cohort will be injected with a product called LPS 24 hours after the infusion of the investigational product, which may stimulate the immune system and cause a temporary inflammatory response in the body. During this time, participants may have mild "flu-like" symptoms. 12 weeks after dose of investigational product, the LPS injection and saline infusion will be repeated.

Read the detailed description

Rationale: SR-878 is a newly developed medicine that aims to treat autoimmune disorders. It works by blocking a protein called iRhom2, which controls the production of small proteins called cytokines. Cytokines are the drivers that keep the inflammatory process ongoing in autoimmune diseases important for regulating the activity of cells in the immune system. This is the first study in humans, and SR-878 will be administered once to each participant in 6 different doses to investigate potential side effects.

Objectives:

  • To assess the safety and tolerability of a single dose of SR-878;
  • To select the optimal dose that is safe and tolerable;
  • To explore any effects of a single dose of SR-878 in the human body;
  • To investigate the connection between the concentration of SR-878 and potential side effects;
  • To assess the amount of immune response against SR-878. Trial design: This clinical study will have six treatment groups, so called cohorts, and each cohort will include 8 participants. In each cohort 6 participants will receive SR-878, and 2 participants will receive a placebo, that is a dummy treatment without active ingredients. The comparison with the placebo is used to better assess the side effects of SR-878. The dose of SR-878 will be gradually increased between cohorts.

After the screening period, participants will be randomly assigned to receive SR-878 or placebo. This is a double-blind study, which means neither the participant nor the study staff, including the study doctor, will know which study medication was used.

The study medication will be administered in a 1-hour long infusion. The participants will be requested to stay 24 hours in the hospital after the infusion, and their medical condition will be monitored, and they will undergo several blood draws.

24 hours after the study medication infusion, participants in the 3rd-6th cohorts, will be injected with a product, called lipopolysaccharide (LPS). It has the ability to boost the body's immune response, even without causing an actual infection. LPS might trigger slight flu-like symptoms (i.e. uneasiness, little fever). Participants will be requested to stay an additional 8 hours in the hospital, and they will undergo several blood samplings and their body's reaction will be monitored. In the first 6 hours, they will receive a saline infusion to keep them hydrated, and in case they find the potential symptoms of the provoked inflammation unbearable, the study doctor will provide a medication (paracetamol) to relieve them.

In the following 12 weeks, participants will be requested to return regularly to the hospital, 10 times in total. During these visits, their medical status will be examined, and blood will be collected. For participants in the 3rd-6th cohorts, 12 weeks after their study medication dose, the LPS injection and the saline infusion will be repeated, and they will stay 8 hours again on the site. They will undergo several blood draws, and their medical condition will be monitored. They will also be requested to return to the site on the next day to repeat these assessments.

Interventions:

  • Participants will receive SR-878 in a 1-hour long infusion once. The dose will depend on the cohort;
  • Participants in the 3rd-6th cohorts will receive LPS injections twice, in a dose of 2 ng/kg body weight.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing SR-878 in people with Healthy Volunteers, run by SciRhom GmbH at 1 site in Austria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 3 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Sponsor decision). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of treatment-emergent adverse event (TEAE) (time frame: Day 1 to Day 85 in Cohorts 1-2 and Day 1 to 86 in Cohorts 3-6). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jun 2025.
