Artax Biopharma Announces First-in-Human Dosing in Phase 1 Clinical Trial for AX-158, Company’s First-in-Class Oral Immunomodulator to Treat T Cell-Mediated Diseases

The Phase 1 Trial, Expected to Conclude in 2022, Will Evaluate Safety, Exposure, and Pharmacokinetics of AX-158 in Healthy Volunteers

AX-158, a Novel, Oral Small Molecule Immunomodulating Agent for the Treatment of T Cell- Mediated Diseases, Selectively Modulates T Cell Responses without Suppression of Immune System Function

Excerpt from the Press Release:

CAMBRIDGE, Mass., Dec. 15, 2021 /PRNewswire/ — Artax Biopharma, Inc., a clinical-stage biotechnology company focused on transforming the treatment of T Cell-mediated diseases, today announces first-in-human dosing in a Phase 1 clinical trial for AX-158, the Company’s first-in-class oral small molecule immunomodulator. AX-158 is the Company’s first oral small molecule immunomodulating agent to enter clinical development for the treatment of T Cell-mediated diseases.

AX-158 employs a first-in-class mechanism of action that selectively modulates T cell responses that play a critical role in healthy immune system function. AX-158 has the potential to treat T Cell mediated diseases without the risk of immunosuppression.

he start of the Phase 1 clinical trial, which marks the beginning of Artax’s AX-158 clinical trial program, is expected to conclude in 2022. The Phase 1 clinical trial will assess the safety, exposure, and pharmacokinetics of AX-158 in healthy volunteers and will include ex-vivo stimulated measures of its pharmacodynamic activity. In preclinical studies, AX-158 demonstrated potential to treat T Cell mediated diseases by decreasing key cytokines including INFγ, TNFα and IL-2 in whole human blood samples.

“Artax has a unique opportunity to make a transformative difference for patients with T Cell-driven conditions, including autoimmune diseases, T Cell malignancies and induced T Cell pathologies – while not impacting the immune system’s ability to mount a strong response to foreign pathogens and infections,” commented Artax Biopharma Chief Executive Officer Joseph Lobacki. “We look forward to the results of this Phase 1 clinical study to inform our future clinical studies evaluating patients managing T Cell-mediated diseases.”

About Artax Science and Immunomodulation
A healthy immune system eliminates harmful foreign pathogens, while being tolerant of self-tissues and organs. The T Cell Receptor (TCR) is central to healthy T Cell function and a well-functioning immune system. When TCR signaling becomes dysregulated, T Cells behave abnormally. This behavior results in T Cell-driven conditions, including autoimmune diseases, T Cell malignancies (lymphomas), and induced T Cell pathologies in which medical treatments result in immune reactions (such as stem cell transplants resulting in acute graft-versus-host- disease or immuno-oncology treatments resulting in immune related-adverse events).

Artax believes immunomodulation – a mechanism through which our investigational agents assist in rebalancing the immune system and eliminating a cause of T Cell-mediated diseases while not impacting patients’ ability to properly fight foreign pathogens – holds great potential.
