Moonlake Immunotherapeutics Plans BLA Submission
Moonlake Immunotherapeutics says it plans to submit a BLA to FDA in the second half of 2026 for sonelokimab to treat hidradenitis suppurativa. A company statement says the decision to move forward followed a successful Type B meeting with FDA that confirmed that the company may establish substantial evidence of effectiveness, without additional clinical trials, using data from the existing VELA-1, VELA-2, and MIRA trials.
Sonelokimab is described as an investigational -40 kDa humanized Nanobody consisting of three VHHs covalently linked by flexible glycine-serine spacers. Nanobodies are said to represent a new generation of antibody-derived targeted therapies that consist of one or more domains based on the small antigen-binding variable regions of heavy-chain-only antibodies (VHH).
