MoonLake Immunotherapeutics(NASDAQ) MLTX

MoonLake Immunotherapeutics makes new medicines for skin and joint diseases. These treatments help people with painful and long-term swelling. The company develops small, targeted proteins to fight inflammation.

What’s in the Pipeline?

• Sonelokimab: Investigational protein-based treatment targeting specific triggers to address chronic inflammatory conditions.
• Dermatology Candidates: Therapeutic focus on inflammatory skin diseases such as hidradenitis suppurativa, which causes painful lumps under the skin.
• Rheumatology Candidates: Investigational treatments for inflammatory joint conditions like psoriatic arthritis, a disease causing joint pain and swelling.

Moving From Lab to Market

• Licensed Sonelokimab from Merck Healthcare KGaA in April 2021 for exclusive clinical development.
• Announced final results from two Phase 3 trials for hidradenitis suppurativa in June 2026.

Why Small Proteins Matter

MoonLake utilizes proprietary Nanobody technology to develop medicines with a lower molecular weight than traditional treatments. This small size is intended to help the medicine penetrate deeper into skin and joint tissues.
