Alpine Immune Sciences Announces First Subjects Dosed in Phase I Clinical Trial for Lead Autoimmune/Inflammatory Disease Program ALPN-101
SEATTLE--(BUSINESS WIRE)--Feb 11, 2019--Alpine Immune Sciences, Inc. (NASDAQ:ALPN), a leading clinical-stage immunotherapy company focused on developing innovative treatments for cancer, autoimmune/inflammatory, and other diseases, today announced successful initiation of dosing in its first-in-human Phase I study of ALPN-101, a first-in-class dual ICOS/CD28 antagonist.
This study will evaluate the safety and tolerability of single- and multiple-ascending intravenous and/or subcutaneous doses of ALPN-101. In addition, pharmacokinetics, pharmacodynamics, and exploratory biomarkers are being evaluated to help determine ALPN-101’s potential for the treatment of autoimmune and inflammatory diseases. The company expects data later in 2019.
“This first dosing in the initial clinical trial of ALPN-101 is an important milestone for Alpine as we have now transitioned to a clinical-stage development company,” stated Mitchell H. Gold, MD, Executive Chairman and Chief Executive Officer of Alpine. “We look forward to further exploring how our first-in-class dual ICOS/CD28 antagonist will potentially improve outcomes of patients suffering from debilitating autoimmune and inflammatory diseases such as GvHD and psoriatic arthritis.”
AIS-A01 is a randomized, placebo-controlled, blinded study in adult healthy volunteers to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics of single and multiple ascending doses of ALPN-101. The trial is being conducted in Australia. More information is available at www.clinicaltrials.gov (Identifier: NCT03748836).
ALPN-101 is a novel Fc fusion protein of a human inducible T cell costimulator ligand (ICOSL) variant immunoglobulin domain (vIgD™), and a first-in-class therapeutic simultaneously inhibiting the CD28 and ICOS inflammation pathways. CD28 and ICOS are closely related costimulatory molecules with partially overlapping roles in T cell activation likely connected to multiple autoimmune and inflammatory diseases. In preclinical models of graft versus host disease, inflammatory arthritis, and multiple sclerosis, ALPN-101 demonstrates efficacy superior to blockade of the CD28 or ICOS pathways alone.
ALPN-101 was engineered using Alpine’s vIgD platform, which uses directed evolution to transform native IgSF proteins into multifunctional protein therapeutics.
About Alpine Immune Sciences, Inc.
Alpine Immune Sciences, Inc. is committed to leading a new wave of functional immune therapeutics. Alpine is employing directed evolution to create potentially powerful multifunctional immunotherapies to improve patients’ lives. Alpine has two lead programs. The first, ALPN-101 for autoimmune/inflammatory diseases, is a dual ICOS/CD28 antagonist, engineered to reduce pathogenic immune responses. The second, ALPN-202 for cancer, is a dual PD-L1/CTLA-4 antagonist and PD-L1-dependent CD28 costimulator intended to combine checkpoint inhibition with T cell costimulation – an approach currently absent from approved checkpoint therapies. Alpine is backed by world-class research and development capabilities, a highly-productive scientific platform, and a proven management team. For more information, visit www.alpineimmunesciences.com.
