Alpine Immune Sciences Presents Clinical and Preclinical Oncology Program Updates at AACR Virtual Annual Meeting I
Alpine Immune Sciences (NASDAQ:ALPN) presented two significant oncology posters at the AACR Virtual Annual Meeting I, April 10-15, 2021. The first highlights the NEON-1 Phase I trial of ALPN-202, focusing on advanced malignancies, with no dose-limiting toxicities reported. The second showcases engineered fusion proteins that enhance tumor immune responses. President Stanford Peng expressed optimism about advancing clinical data for ALPN-202 in future meetings, reflecting the company's commitment to innovative immunotherapy solutions.
- Ongoing NEON-1 Phase I trial of ALPN-202 shows no dose-limiting toxicities.
- Successful demonstration of engineered fusion proteins providing potent anti-tumor immunity.
- None.
Alpine Immune Sciences, Inc. (NASDAQ:ALPN), a leading clinical-stage immunotherapy company focused on developing innovative treatments for cancer and autoimmune/inflammatory diseases, today announced the presentation of two posters on the company’s clinical and preclinical oncology programs at the American Association for Cancer Research (AACR) Virtual Annual Meeting I, taking place April 10-15, 2021.
CT213: NEON-1: A First-in-Human Phase I Open-Label Study of ALPN-202, a Conditional CD28 Costimulator and Dual Checkpoint Inhibitor, in Advanced Malignancies
- Dr. Mark Voskoboynik from Nucleus Network and The Alfred Hospital in Melbourne, Australia, presented a Trials in Progress poster describing the ongoing first-in-human, phase 1 clinical trial involving monotherapy with ALPN-202, the company’s lead oncology program.
- The trial, NEON-1, includes separate parts for dose escalation and expansion cohorts, and is enrolling patients with advanced solid tumors or lymphoma. Dose escalation continues to progress, with no dose-limiting toxicities to date.
P1740: Engineered Variant Domain Fusion Proteins Provide Checkpoint Inhibition and Tumor Antigen Dependent CD28 Costimulation Resulting in Potent Anti-Tumor Immunity
- Alpine researchers demonstrated the use of directed evolution to engineer novel variant immunoglobulin domain (vIgD) Fc fusion proteins that enable tumor antigen-dependent CD28 costimulation.
- The fusion proteins targeted the PD-L1 or HHLA2 tumor antigens, and demonstrated potent efficacy in antigen-positive tumor models in vitro and in vivo.
“Together, these presentations summarize the potential for an exciting, emerging CD28 costimulation portfolio,” said Stanford Peng, MD, PhD, Alpine’s President and Head of Research and Development. “We look forward to the opportunity to present initial clinical data from NEON-1 at an upcoming scientific meeting and are optimistic about the potential to advance one or more of our preclinical programs toward the clinic in the near future.”
Full abstracts are available on the AACR Virtual Annual Meeting website and posters for both presentations are available on the Scientific Publications page of Alpine’s website.
About Alpine’s Directed Evolution Platform
Alpine’s directed evolution platform engineers native immune proteins, primarily of the immunoglobulin or tumor necrosis factor (receptor) superfamilies, into novel functional domains: variant immunoglobulin domains (vIgDs) and/or variant TNF domains (vTDs), respectively. These domains have acquired unique functional properties designed to benefit patients with cancer or inflammatory diseases.
About ALPN-202
ALPN-202 is a first-in-class, conditional CD28 costimulator and dual checkpoint inhibitor with the potential to improve upon the efficacy of combined checkpoint inhibition while limiting significant toxicities. Preclinical studies of ALPN-202 have successfully demonstrated superior efficacy in tumor models compared to checkpoint inhibition alone. NEON-1 (NCT04186637), a Phase 1 study of ALPN-202 in patients with advanced malignancies, is currently enrolling. Alpine is also targeting the initiation of NEON-2, a Phase 1 combination study of ALPN-202 and a PD-1 inhibitor, later this year.
