Alpine Immune Sciences Announces Oral Presentation of ALPN-101 at the 61st American Society of Hematology Annual Meeting and Exposition

On November 6, 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, reported an abstract has been accepted for an oral presentation highlighting the company’s lead autoimmune/inflammatory program ALPN-101 at the 61stAmerican Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition to be held December 7-10, 2019 in Orlando, FL (Press release, Alpine Immune Sciences, NOV 6, 2019, View Source [SID1234550436]).

The Company will present on its upcoming Phase 1/2 BALANCE study of ALPN-101 in steroid-resistant or steroid-refractory acute Graft-versus-Host Disease (GvHD). ALPN-101 is a first-in-class, dual inhibitor of the CD28 and ICOS costimulatory pathways with strong preclinical and translational rationale in GvHD.

Last year, preclinical data on ALPN-101 was included in an oral presentation at the 60th ASH (Free ASH Whitepaper) Annual Meeting, highlighting the novel role ICOS ligand (ICOS-L) plays in acute GvHD and extending what is currently understood about the CD28/B7 protein family in disease pathogenesis. Since then, Alpine has been conducting a first-in-human, randomized, placebo-controlled single- and multiple-ascending dose Phase I study in adult healthy volunteers. "This year’s presentation will discuss the translational and therapeutic potential of ALPN-101 based on our learnings to date," indicated Stanford Peng, M.D. Ph.D., President and Head of Research and Development at Alpine.

61st ASH (Free ASH Whitepaper) Annual Meeting Oral Presentation

Title: An Open Label Study of ALPN-101, a First-in-Class Dual CD28/ICOS Antagonist, in Subjects with Steroid-Resistant or Steroid-Refractory Acute Graft Versus Host Disease (aGvHD)
Presenter: Dr. Jan Hillson, Senior Vice President, Clinical Development, Alpine
Session Name: 802. Chemical Biology and Experimental Therapeutics: Novel Compounds and Mechanisms of Action (9:30 – 11:15 AM ET)
Oral Presentation Date and Time: Sunday, December 8, 2019: 11:00 AM ET
Location: OCCC, W414AB
About Graft Versus Host Disease (GvHD)

Graft versus host disease (GvHD) is the most common life-threatening complication of a hematopoietic cell transplant. It occurs when donor cells see recipient cells as different and attack them. Acute GvHD typically occurs within the early weeks and months after transplant, usually involving the skin, liver and gastrointestinal tract. Despite extensive studies of many different therapies in GvHD, corticosteroids remain its primary treatment.

About ALPN-101

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 designed to inhibit simultaneously 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, connective tissue disease and multiple sclerosis, ALPN-101 demonstrates efficacy superior to blockade of the CD28 and/or ICOS pathways alone.

Alligator Bioscience: ATOR-1017 Induces Long-Lasting Immunity – New Preclinical Data to be presented at SITC 34th Annual Meeting

On November 6, 2019 Alligator Bioscience (Nasdaq Stockholm: ATORX), reported that the company will present new preclinical data showing that their drug candidate ATOR-1017 can induce a long-lasting immunological memory which is of great importance in a potential future patient setting (Press release, Alligator Bioscience, NOV 6, 2019, View Source [SID1234550435]). The results will be presented at the ongoing Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 34th Annual Meeting. The ATOR-1017 drug candidate is in development for the treatment of metastasized cancer.

Furthermore, the results show that treatment with ATOR-1017 activates the immune system in the tumor area but not systemically. These preclinical data support a tumor-directed activity of ATOR-1017. The aim is to focus the immune attack towards the tumor in order to increase efficacy and minimize side effects for the patient. ATOR-1017 is currently about to initiate Phase I clinical study and dosing of the first patient is expected shortly.

"These preclinical data support the potential of ATOR-1017 to generate a strong and long-lasting immune response or even to induce immunity to cancer. This is our fourth asset to enter the clinic and with its unique tumor-directed profile, we continue to build a clinical pipeline of the next generation cancer immunotherapies", said Per Norlén, CEO of Alligator Bioscience.

The upcoming Phase I study will be a first-in-human, dose escalation study in patients with advanced cancer. It will be conducted at three sites in Sweden and will enroll up to 50 patients. The primary objective of the study is to assess the safety and tolerability of ATOR-1017 and to determine the recommended dose for the subsequent Phase II studies.

Karin Enell Smith, Senior Scientist at Alligator Bioscience will present a poster with the title "ATOR-1017, a 4-1BB antibody developed for tumor-directed immunotherapy of cancer" on Saturday November 9 at the SITC (Free SITC Whitepaper) 34th Annual Meeting held in National Harbor, Maryland, US. The poster presentation will be available on the Alligator web site View Source on the day of the presentation.

About ATOR-1017
ATOR-1017 is an immunostimulatory IgG4 antibody that activates tumor-specific T cells and NK cells through the costimulatory receptor 4-1BB. T cells and NK cells have the capacity to detect and kill tumor cells, making 4-1BB a particularly attractive target for cancer immunotherapy. ATOR-1017 has a unique profile related to the fact that its immunostimulatory function is stronger in areas where immune cells are abundant, notably in tumors. This creates an opportunity for a strong immune activation, while minimizing side effects for the patient.
