– New study follows completion of first-in-human Phase 1b trial in atopic dermatitis patients, in which selectION observed safety and tolerability of si-544 in the treatment of T cell autoimmunity
– Recruitment is underway, with topline results expected in 4Q24
SAN DIEGO, CA, USA, and MUNICH, Germany I May 28, 2024 I selectION, Inc. (“selectION” or the “Company”), a clinical-stage biopharmaceutical company developing novel treatments for T cell-mediated autoimmune diseases, today announced the initiation of a Phase 1b trial with its lead compound si-544 in adult patients with psoriasis vulgaris (Ps) or psoriatic arthritis (PsA). si-544 is a selectivity-optimized peptide blocking the Kv1.3 ion channel. Kv1.3 is a key target in autoimmunity, which the Company believes has the potential to set a new standard for safety and tolerability in the treatment of T cell autoimmunity. Enrollment is ongoing and topline data are expected in the fourth quarter of 2024.
This new clinical study is designed as a multicenter, Phase 1b, double-blind, placebo-controlled trial in adults with mild to severe Ps or PsA. The Company anticipates enrolling up to 40 patients with Ps, of which up to 16 patients may also have PsA.
This psoriasis study follows the recent completion of the Company’s first-in-human Phase 1b trial in atopic dermatitis patients, in which the Company observed safety and tolerability of si-544 in adult patients with mild to severe atopic dermatitis. The current Phase 1b trial design in patients with Ps or PsA should also allow for the evaluation of efficacy signals. Patients will undergo a 4-week treatment period and a subsequent 12-week follow-up period.
While the primary endpoints of the trial are safety and tolerability, secondary endpoints include the assessment of PD markers such as inflammatory cytokine levels.
Andreas Klostermann, PhD, Chief Scientific Officer and co-founder of the Company said, “We are focused on expanding clinical development of si-544 in autoimmune indications, and we are looking forward to the results of this second, larger trial in a
T cell-driven disorder.”
Antonius Schuh, PhD, Chairman and CEO of selectION, Inc. added, “The promising data from our successful clinical study in atopic dermatitis patients provide further evidence that direct targeting of disease-associated, chronically activated T cells via Kv1.3 inhibition may provide effective and safe treatments for patients living with a broad variety of autoimmune diseases.”

About si-544
si-544, the Company´s lead drug candidate, is blocking Kv1.3, a specific ion channel involved in the activation and proliferation of TEM cells, with what the Company believes to be class leading selectivity. TEM cells lie at the root of many autoimmune indications such as atopic dermatitis, psoriasis, rheumatoid arthritis, or multiple sclerosis, but also of certain rare cancers like lymphomas.
si-544 has demonstrated what the Company believes is an excellent safety and tolerability profile in a recently completed Phase 1b clinical trial in atopic dermatitis patients, with study results also indicating an initial efficacy signal. Previously, si-544 has demonstrated what the Company believes is excellent efficacy in animal and human T cell models.
The compound is a potent immuno-selective agent addressing a significant unmet medical need by functionally inhibiting and eliminating disease-specific, chronically activated TEM cells while maintaining full immunocompetence.
