THERAPEUTIC APPROACH
Transforming Cancer Immunotherapy to Treat More Patients, Better
IO therapies have revolutionized cancer care, however the benefits are only realized in a subset of patients and indications, due to hurdles such as:
Our Approach
The Ƶ Solution
Ƶ has developed a singular approach reaching new levels of immune system engagement to overcome cancer immunotherapy hurdles by:
Systemic and durable tumor inflammation
Increased tumor antigen presentation
Massive T cell activation and infiltration
Tumor suppression counteracted by constant immune cell influx
Concerted innate and adaptive immune response
Immunostimulation to fight tumor cells from within
Our Unique AdaptInnate Approach
Ƶ is leveraging its unique AdaptInnate approach in a new class of product candidates harnessing the immunostimulatory and anti-tumoral properties of arenaviruses to trigger a highly precise and comprehensive immune response against primary tumors and their metastases.
By specifically infecting, persisting and replicating inside of cancerous and antigen-presenting cells without destroying them, the systemically administrable candidates aim to trigger a tailored immune reaction from inside the tumor. This novel, non-oncolytic approach results in the induction of targeted, effective, and durable anti-tumor activity involving both the innate and adaptive arms of the immune system.

The AdaptInnate Approach

Sytemic application of arenavirus-based product candidate
Body-wide infection of antigen-presenting cells in key lymphatic organs and of tumor cells without destroying host cells
A Unique Drug Candidate Poised to Become a Novel Class in Immuno-Oncology
Our Lead Candidate ABX-001
Ƶ is currently advancing ABX-001, the first candidate from its proprietary AdaptInnate platform, towards clinical evaluation.
In preclinical studies, systemic administration of ABX-001 has shown marked tumor regression in multiple tumor models, induction of tumor-specific T cells, as well as an excellent pre-clinical safety profile in non-human primates. In addition, a robust and scalable cGMP manufacturing process, which allows for manufacturing at high yield, has been established.
Based on these promising results, Ƶ is currently preparing the initiation of a first-in-human clinical trial with ABX-001 in patients with solid tumors, which is expected to start in 2025.
Ƶ
Our Scientific Foundation
Ƶ was founded to translate the innovative research of immunology and virology experts Karl Lang and Philipp Lang into novel anti-cancer therapies. They identified a specific set of mammarenaviruses that preferentially infect and proliferate in cancer cells, which results in a very strong and targeted immune response against the cancer. These findings provided a novel strategy to enable a precise immune response and activate all relevant immune cell types against primary tumors and metastases.
