A Phase 2 Study to Investigate the Efficacy, Safety and Tolerability of Remibrutinib (LOU064) in Adult Patients With Papulopustular Rosacea (PPR)

Study details
This is a multicenter, randomized, participant and Investigator-blinded, placebo-controlled, parallel-group Phase 2 study designed to evaluate the efficacy, safety, and tolerability of remibrutinib in adults with moderate-to-severe PPR. Following a screening period of up to 30 days, which can be extended by a further 2 weeks only to allow washout from rosacea treatments and other systemic therapies as specified in the prohibited medication section, eligible participants will be randomized at baseline to receive either remibrutinib or matching placebo for a 16-week double-blind treatment phase. A safety follow up visit will occur approximately 30 days after the final dose.

Who can take part?
Inclusion Criteria
- Signed informed consent must be obtained prior to participation in the study.
- Adult ≥18 years with a clinical diagnosis of PPR.
- Moderate-to-severe disease defined by a modified Investigator's Global Assessment (IGA) score of 3 or 4
- The presence of 15 - 60 inflammatory (papular/pustular, max. 2 nodular) facial lesions at screening, with at least 15 lesions present at Day 1 (Baseline).
- Completed requisite washout of systemic antibiotics (30 days) and other prohibited systemic therapies before randomization.
- Willingness to refrain from initiating treatments or undergoing procedures that target or impact PPR during the double-blind period, and to use only protocol-allowed products.
Exclusion Criteria
- Presence of more than 2 nodular inflammatory lesions
- Any active facial dermatoses or skin disease or condition that may interfere with assessment of PPR (e.g., seborrheic dermatitis, perioral dermatitis, acne, acneiform eruptions from biologic medications, steroid-induced dermatitis resembling rosacea or acne).
- History of hypersensitivity to any of the study treatments or its excipients or to drugs of similar chemical classes
- Use of biologics within five half-lives prior to screening or until the expected pharmacodynamic (PD) effect has returned to baseline, whichever is longer; or longer if required by local regulations
- Use of small molecules and/or immunosuppressants that are not corticosteroids within 5 half-lives or within 30 days prior to screening, whichever is longer; or longer if required by local regulations
- Any use of systemic corticosteroids, systemic antibiotics, or topical treatments (including corticosteroids, antibiotics, ivermectin, azelaic acid, or metronidazole) within 30 days prior to randomization, or any planned use of these agents during the study treatment period.
- History of live attenuated vaccine within 6 weeks prior to randomization or requirement to receive these vaccinations at any time while on study treatment.
- Use, planned use, or failure to meet the protocol-defined washout periods for prohibited therapies. In particular, patients with pretreatment with remibrutinib or another BTK-inhibitor within 4 months prior to randomization.
Other protocol-defined inclusion/exclusion criteria may apply.

The purpose of this research study is to learn whether an investigational treatment can reduce the number of inflamed bumps and pus-filled spots (inflammatory lesions) in adults with moderate-to-severe papulopustular rosacea. The study will also look at safety and tolerability (how well people can handle the treatment).
Participants will receive either the investigational treatment or a placebo. A placebo looks like the investigational treatment but does not contain active medication. Participants will take the assigned study treatment for 16 weeks. Some people may need to stop certain rosacea or other treatments before starting the study treatment. Participants will have a safety follow-up visit about 30 days after the last dose.
This study may be an option for
Adults with moderate-to-severe papulopustular rosacea may be able to participate if they:
- Are age 18 or older and have papulopustular rosacea
- Have moderate-to-severe symptoms
- Have a certain number of inflamed facial lesions at screening and at the start of the study
- Have completed required “washout” time (time off) from certain antibiotics and other treatments before starting the study
- Are willing not to start new treatments or procedures that target or affect papulopustular rosacea during the main study treatment period, and to use only products allowed by the study
Study timeline and visits:
Screening lasts up to 30 days and may be extended by up to 2 weeks to allow time off certain treatments. Study treatment lasts 16 weeks. There is a safety follow-up visit about 30 days after the final dose.
