• Mobilizing the Immune System

    A clinical-stage biopharmaceutical company leveraging from its multiple drug development platforms to treat patients with inflammatory diseases, viral infections, and cancer.
  • ABX464

    Fighting Inflammatory Diseases

    Abivax’s lead candidate ABX464, a potent anti-inflammatory agent, is being tested in a Phase 2b clinical trial for its potential to bring clinical benefit to patients with ulcerative colitis, and potentially other inflammatory indications.
  • ABX464

    Developing a Functional Cure for HIV

    ABX464 is a Phase 2 candidate designed to functionally cure HIV by reducing the viral reservoir and is the first ever drug candidate to demonstrate this reduction in patients.
  • ABX196

    Tackling Cancer

    A small molecule agonist of invariant Natural Killer T-Cells (iNKT) is currently being tested in a Phase 1/2 clinical trial for treatment of hepatocellular carcinoma (HCC).

About Us

Abivax is developing therapies that stimulate the body’s natural immune system machinery. A clinical-stage company, Abivax leverages its immune enhancing and antiviral platforms to develop drug candidates to treat inflammatory diseases, HIV, and liver cancer.

Its lead clinical candidate, ABX464, has demonstrated the potential to treat inflammatory diseases and to reduce the viral reservoir in HIV.

With five programs in clinical testing, a trial in Crohn’s disease to start and three projects in research and preclinical development, Abivax’s pipeline is strong and diversified, addressing many unmet needs.

Clinical Programs

  • ABX464 COVID-19

    ABX464 is an oral, first-in-class, small molecule that has been shown to inhibit the replication of the HIV virus and to have a sustainable anti-inflammatory effect in patients suffering from ulcerative colitis along with tissue repair properties. In addition, new in vitro data also have shown the ability of ABX464 to inhibit the replication of SARS-CoV-2 (COVID-19). With a potential triple effect that includes 1) inhibition of the SARS-CoV-2 virus replication, 2) prevention and treatment of the acute respiratory distress syndrome (ARDS) caused by hyperinflammation, as well as 3) limit longer-term pulmonary dysfunction due to resulting tissue damage in the lungs, ABX464 could be a promising candidate for the treatment of the COVID-19 disease, especially in its severe form. Therefore, a Phase 2b/3 study with ABX464 in 1,034 patients with COVID-19 is being conducted in Europe and Latin America to assess whether the drug candidate can prevent the cytokine storm and ARDS in these patients.

  • ABX464 UC

    ABX464 is an oral, first-in-class, small molecule that has demonstrated safety and profound anti-inflammatory activity in preclinical trials and in a Phase 2a clinical trial, ABX464-101, to treat ulcerative colitis (UC). Patients who completed the induction study had the option to roll over into a 12-month open-label extension study, ABX464-102, in which 22 out of 23 eligible patients were enrolled.

  • ABX464 Crohn’s Disease

    ABX464 is an oral, first-in-class, small molecule that has demonstrated safety and profound anti-inflammatory efficacy in a completed Phase 2a induction study as well as a 24-month maintenance study in patients with moderate-to-severe ulcerative colitis (UC).
    Due the clinical similarities of Crohn’s disease (CD) and UC, and the predictability of the DSS model for both UC and CD, several key opinion leaders (KOLs) are confident that ABX464 will also show beneficial effects in patients suffering from CD.

  • ABX464 Rheumatoid Arthritis

    ABX464 is an oral, first-in-class, small molecule that has demonstrated safety and profound anti-inflammatory activity in a completed Phase 2a induction study as well as a 12-month maintenance study in patients with moderate-to-severe ulcerative colitis (UC). In addition to the clinical observations in UC patients, Abivax generated promising pre-clinical data from collagen-induced arthritis animal models.

  • ABX464 HIV

    ABX464 is an oral, first-in-class, novel, small molecule inhibiting HIV replication through an entirely new mechanism of action. For the first time in the treatment of HIV, this molecule could reduce or eliminate the viral reservoirs, and thus potentially deliver a long-lasting virological suppression in HIV-patients.
