Frequently asked questions about Sonelokimab

What is Sonelokimab used for?

Sonelokimab is an investigational antibody being developed for hidradenitis suppurativa and psoriatic arthritis. It is currently in Phase 3 clinical trials for moderate to severe hidradenitis suppurativa. The drug is also being studied in adolescents with this condition.

Who is developing Sonelokimab?

Sonelokimab is being developed by MoonLake Immunotherapeutics, a biopharmaceutical company traded under the ticker MLTX. The company is conducting multiple clinical trials to evaluate the drug's efficacy and safety in inflammatory skin conditions.

What phase is Sonelokimab in?

Sonelokimab is in Phase 3 clinical development for hidradenitis suppurativa. Several Phase 3 trials have been completed, and one additional Phase 3 study is active but not recruiting participants. The drug has received Fast Track designation from the FDA.

What clinical trials is Sonelokimab in?

Sonelokimab has been studied in several clinical trials, including NCT05322473, a Phase 2 trial in hidradenitis suppurativa, and NCT06411379 and NCT06411899, both Phase 3 trials in moderate to severe hidradenitis suppurativa. An ongoing Phase 3 trial, NCT06768671, is evaluating the drug in adolescents.

How is Sonelokimab administered in clinical trials?

Sonelokimab is administered via subcutaneous injection in clinical trials. The Phase 3 studies evaluate subcutaneous sonelokimab compared with placebo in adult participants with moderate to severe hidradenitis suppurativa. The adolescent study also uses subcutaneous administration.

Is Sonelokimab being studied in adolescents?

Yes, Sonelokimab is being studied in adolescents aged 12 years and older with moderate to severe hidradenitis suppurativa. The Phase 3 trial NCT06768671, known as VELA-TEEN, is an open-label, single-arm study evaluating the pharmacokinetics and safety of subcutaneous sonelokimab in this population.
