What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the effectiveness and safety of a new treatment for adults with moderate to severe hidradenitis suppurativa, a painful skin condition. The treatment aims to reduce symptoms.

Do I need to stop my current medications to join the trial?

The trial information does not specify if you need to stop taking your current medications. However, it mentions that participants should have had an inadequate response to systemic antibiotics, suggesting that some medications might be continued. Please consult with the trial investigator for specific guidance.

Is Sonelokimab safe for humans?

Sonelokimab has been tested in phase I and II studies for psoriasis, showing promising safety results. These studies suggest it is generally safe for human use. ^{1 2 3 4 5}

What makes the drug Sonelokimab unique for treating psoriasis?

Sonelokimab is unique because it is a trivalent nanobody derived from camelid antibodies, targeting both IL-17A and IL-17F, which are involved in the inflammation process of psoriasis. This dual targeting approach may offer better disease control compared to treatments that only target IL-17A. ^{1 2 4 6 7}

What data supports the effectiveness of the drug Sonelokimab?

Research shows that Sonelokimab, a drug targeting IL-17A and IL-17F, has shown promising results in early studies for treating psoriasis, a skin condition. It works by blocking specific proteins involved in inflammation, and studies have shown it can help improve symptoms in patients with this condition. ^{1 2 4 5 7}

Are You a Good Fit for This Trial?

Inclusion Criteria

Participant must be, in the opinion of the investigator, at both the Screening Visit and study treatment initiation, a suitable candidate for treatment with adalimumab per approved local product information.

You have previously tried antibiotics to treat your hidradenitis suppurativa, but they did not work or caused side effects.

Participant has hidradenitis suppurativa lesions present in ≥2 distinct anatomical areas, at least one of which must contain single or multiple fistulas (i.e., be Hurley Stage II or III);

Exclusion Criteria

You are allergic to sonelokimab or any substances used to make it.

Participant has a draining fistula count of ≥20 at the Screening Visit;

You have another ongoing skin condition that might affect the evaluation of your hidradenitis suppurativa.

Long-term

What Are the Treatments Tested in This Trial?

Interventions

• Sonelokimab

How Is the Trial Designed?

Group I: sonelokimab dose 2 Experimental Treatment 1 Intervention

Subjects randomized to this arm will receive assigned sonelokimab dosage regimen and placebo to maintain the blinding with adalimumab and placebo arms during the Treatment Period.

Group II: sonelokimab dose 1 Experimental Treatment 1 Intervention

Subjects randomized to this arm will receive assigned sonelokimab dosage regimen and placebo to maintain the blinding with adalimumab and placebo arms during the Treatment Period.

Group III: adalimumab Active Control 1 Intervention

Subjects randomized to this arm will receive adalimumab during the Double-Blind Treatment Period and will be reallocated to receive sonelokimab dosage regimen during Part B.

Group IV: Placebo Placebo Group 1 Intervention

Subjects randomized to this arm will receive placebo during the Double-Blind Treatment Period and will be re-randomized to receive a sonelokimab dosage regimen during Part B.

Published Research Related to This Trial

Bimekizumab, a dual inhibitor targeting both IL-17A and IL-17F, has shown efficacy and safety in treating psoriasis and psoriatic arthritis across multiple phases of clinical trials (I, II, and III).

Sonelokimab, a trivalent nanobody also targeting IL-17A and IL-17F, has demonstrated promising results in early phase studies for psoriasis, indicating potential for effective treatment options in these chronic immune-mediated disorders.

Dual inhibition of IL-17A and IL-17F in psoriatic disease. Iznardo, H., Puig, L.[2021]

In a phase 2b trial involving 313 participants with moderate to severe plaque-type psoriasis, sonelokimab demonstrated significant efficacy, with 48.1% of patients in the 30 mg group and up to 88.2% in the 120 mg augmented load group achieving clear or almost clear skin (IGA score of 0 or 1) at week 12, compared to 0% in the placebo group.

Sonelokimab exhibited a safety profile comparable to secukinumab, with mostly mild to moderate adverse events, and a notable incidence of manageable Candida infections in the sonelokimab group, indicating it is a safe treatment option for psoriasis.

Ixekizumab, an anti-interleukin 17A monoclonal antibody, was well tolerated in patients with rheumatoid arthritis over a 64-week period, with 87% of biologic-naive and 62% of TNF-IR patients completing the study.

Clinical improvements in rheumatoid arthritis symptoms, measured by various scales, were maintained or improved from Week 16 to Week 64, indicating the long-term efficacy of ixekizumab.
