PARIS, France, May 14, 2020 – 06:00 a.m. (CET) – Abivax SA (Euronext Paris: FR0012333284 – ABVX), a clinical-stage biotechnology company harnessing the immune system to develop novel treatments for inflammatory diseases, viral diseases and cancer, announces today it has received clearance from France’s National Agency for the Safety of Medicines (ANSM) and French Ethics Committee (CPP) to initiate a randomized, double-blind, placebo-controlled Phase 2b/3 trial of ABX464 to prevent severe inflammation that leads to acute respiratory distress syndrome (ARDS) in 1,034 COVID-19 elderly or high-risk patients (miR-AGE trial).
Oral, once-daily ABX464 has demonstrated impressive efficacy in a Phase 2a trial in another severe inflammatory disease, ulcerative colitis, and its unique molecular mechanism of action supports the rationale to treat the cytokine storm and hyper-inflammation syndrome observed in COVID-19 patients. The hyper-inflammation in the lung is the primary cause of the respiratory distress and potential death of patients. ABX464 has been shown to upregulate miR-124,, a “physiological brake” of inflammation, and miR-124, a micro-RNA, down-regulates the multiple chemo- and cytokines involved in the COVID-19 cytokine storm, including TNF alpha, IL-1 beta, G-CSF, IL-6, MCP-1 and IL-17. In addition, unlike other potent anti-inflammatories that specifically target a single cytokine, ABX464 has not been associated with increased vulnerability to opportunistic infections.
Furthermore, new breakthrough data (see Abivax second press release) show that ABX464 inhibits replication of SARS-CoV-2 (COVID-19 virus) in an in vitro stringent human pulmonary epithelium model, making ABX464 the only drug candidate with the desirable triple action to treat COVID-19 patients: anti-inflammatory, antiviral and tissue repair, thanks to its overexpression of miR-124. In addition, convenient oral dosing (one capsule per day) allows for early treatment of hospitalized as well as non-hospitalized patients.
This rigorous Phase 2b/3 trial will be performed according to high international clinical standards at 50 hospitals in France and other European countries, following the past six weeks of already completed intense preparation. The study will include robust procedures for patient selection, randomization against placebo and study monitoring as well as data collection, management, and statistical analysis.
Key elements of the trial:
- ABX464 oral dosing (50 mg once-daily) vs placebo and standard of care, 2 to 1 randomization
- 1,034 high-risk COVID-19 patients (older than 65 years or adults with risk factors)
- Enrolling hospitalized and non-hospitalized patients with confirmed SARS-CoV-2 infection, recruitment is expected to be completed within a few months
- Main evaluation criterion: absence of high-flow oxygen use or assisted ventilation or death within 28 days
- Multiple clinical and biological secondary endpoints
- Treatment (ABX464 or placebo and standard of care) duration: 28 days
- 50 French and European hospitals
This study will also address a number of crucial questions, notably ABX464’s ability to prevent the acute respiratory distress syndrome (ARDS) in elderly patients with or without risk factors, in younger patients with risk factors, and secondary impacts of a SARS-CoV-2 infection on pulmonary function. In times of crisis, treatment decisions are often based on small and sometimes not correctly controlled clinical trials. This rigorously conducted study is designed in a way to provide comprehensive clinical data on the safety and efficacy of ABX464 in COVID-19 patients.
“The miR-AGE trial with ABX464 has been endorsed by renowned experts in France, Europe, and the U.S.,” said Philippe Pouletty, M.D.,Chairman of the Board of Abivax and CEO of Truffle Capital. “Our mission is to develop drugs that improve and save patients’ lives. I am proud that we can utilize Abivax’s research and expertise to join the fight against the COVID-19 pandemic that affects our world. The COVID-19 physiopathology is complex and we must remain cautious about the potential success of the miR-AGE trial. We hope that ABX464, with its unique antiviral, anti-inflammatory and tissue repair properties and convenient oral administration, can prove to be a promising therapy for COVID-19 patients.I wish to thank our tremendous team who has been working relentlessly to launch this project, the Abivax Board of Directors and scientific advisory board, as well as the investigators, Bpifrance, ANSM and CPP for this unprecedented and collaborative effort. In parallel to the miR-AGE trial, Abivax will continue to work on its ongoing and planned clinical programs, especially the progress of the ABX464 international Phase 2b trial in ulcerative colitis.”
Prof. Hartmut Ehrlich, M.D., CEOof Abivax, said: “In the current situation, where there is no vaccine and no herd immunity against COVID-19, we rapidly require a treatment that will reduce the severity of this disease. Unfortunately, no prophylactic or therapeutic treatment has shown much efficacy in any rigorous trial to treat the severe form of COVID-19; helping clinicians prevent respiratory distress and death in COVID-19 patients and limit longer-term pulmonary damage is of paramount necessity. In addition, relieving hospital intensive care units of the tremendous burden that is being placed upon them is a top priority. ABX464 is an orally available small molecule that may have the potential to achieve some of these goals because of its unique mechanism and its ease of use. The robust, rigorous design of the miR-AGE ABX464 trial ensures we will draw valid scientific and medical conclusions. If the miR-AGE trial is successful, we will work with regulatory authorities to make ABX464 available as rapidly as possible. ABX464 already has demonstrated that it was safe in clinical trials to treat other inflammatory diseases. We already have ABX464 capsules in stock to treat app. 50,000 patients and could scale-up ABX464 manufacturing for over one million patients within months.”
Eric Cua, M.D., Infectiologist at the University Hospital Center (CHU) of Nice, Principal Investigator and Prof. Jean-Luc Diehl, M.D., Head of Medical ICU at Georges Pompidou European Hospital (HEGP) and Chairman of the Steering Committee for the miR-AGE trial, said: “We fully endorse Abivax’s clinical trial to assess whether early anti-inflammatory treatment with ABX464 will improve patients’ outcomes. ABX464 is a late-stage development compound with a new mechanism of action, specifically, by miR-124 overexpression induced antiviral activity and down-regulation of important pro-inflammatory chemo- and cytokines like TNF alpha, IL-6, MCP-1 and IL-17, for the treatment of patients with inflammatory diseases. The molecule has already demonstrated transformational efficacy data in patients with moderate-to-severe ulcerative colitis by achieving clinical remissions in patients who did not improve on biologics like Adalimumab, Vedolizumab and Ustekinumab. In addition, ABX464 has shown a favorable safety profile in more than 300 volunteers and patients with HIV or ulcerative colitis. Based on these data, we believe that ABX464 should be urgently tested against placebo plus standard of care in this robust, double-blinded and sufficiently powered miR-AGE clinical trial in COVID-19 patients before they develop an acute respiratory distress syndrome.”
The CHU of Nice and its DCRI will assist in the international coordination of the Abivax sponsored trial, and the HEGP central laboratory will conduct immune- and hemato-monitoring of patients.
Update on Abivax’s global clinical development program: The ongoing Phase 2b clinical trial with ABX464 in ulcerative colitis remains an Abivax top priority. Given the COVID-19 crisis and related emergency situations in many hospitals, patient recruitment is now expected to be completed by the end of 2020 and first high-level results are expected in Q2 2021. The Phase 2a clinical study with ABX464 in rheumatoid arthritis should complete recruitment in 2020 with first high-level results expected in early Q1 2021. For Abivax’s ongoing clinical trial with ABX196 to treat patients with hepatocellular carcinoma, the first data of the escalation phase of the study will probably be available during H1 2021.
