PARIS, FRANCE / ACCESSWIRE / September 23, 2021 / Abivax SA (Euronext Paris: FR0012333284 – ABVX), a clinical-stage biotechnology company developing novel therapies that modulate the immune system to treat chronic inflammatory diseases, viral infections, and cancer, today announces its 2021 half-year financial results, as of June 30, 2021, and provides an update on its clinical development progress. The financial statements for the first half of 2021, approved by the Company’s Board of Directors on September 21, 2021, have been audited and the certification report is being prepared by the Company’s external auditors.
“2021 has been a particularly positive and eventful year for Abivax. We announced excellent phase 2b clinical top-line and subsequent full results for the treatment of ulcerative colitis patients as well as very promising data of the phase 2a study in rheumatoid arthritis, both conducted with our lead compound ABX464. It is particularly encouraging to see, that our one-year and three-year long-term data of the ongoing phase 2a and phase 2b open-label maintenance studies confirm the sustained efficacy as well as the continued good safety profile of ABX464 in UC patients. We are also pleased that our late breaking abstract on the UC phase 2b data has been selected for an oral presentation at this year’s United European Gastroenterology conference. This is another external validation of the potential of ABX464 to become an efficient durable treatment for patients suffering from UC.”, said Prof. Hartmut J. Ehrlich, M.D., CEO of Abivax.
He continued: “Additional laboratory analyses now also reinforce the novelty and differentiation factors of the mechanism of action of ABX464 with a statistically significant upregulation of miR-124, a specific, physiologic, anti-inflammatory microRNA, observed in rectal tissues of patients across all dose groups. With these very positive clinical results and laboratory data, Abivax engaged in advanced interactions with the relevant regulatory authorities to launch its priority phase 3 clinical program with ABX464 in ulcerative colitis as quickly as possible. There is an urgent need for long-term efficacious and safe new drugs in the field of inflammatory bowel diseases. The entire Abivax team and its scientific advisory board are committed to take ABX464 to the finish line and provide the many patients suffering from these very debilitating chronic diseases with a new, potent and well-tolerated therapeutic management option.”
Didier Blondel, CFO of Abivax, added: “Abivax successfully secured EUR 85M major financing in July under attractive terms, with the pricing of an oversubscribed capital increase of EUR 60M and convertible bonds of EUR 25M. With our current and available cash resources, together with the planned outcome of the prioritization of our clinical development activities for ABX464, our operations are expected to be funded until the end of Q3 2022. We are now carefully evaluating the strategic possibilities for the Company. Our strategic priority remains a potential partnering with a large pharma or biotech company, under the premises that the full potential of ABX464 in inflammatory bowel diseases as well as in the entire chronic inflammatory field is taken into account. As an alternative strategic option, we are also looking into additional financing opportunities, notably in the US and in Europe, that would maximize shareholder value.”

OPERATING HIGHLIGHTS: PORTFOLIO UPDATE
ABX464 phase 2b clinical induction study in ulcerative colitis
In May and September 2021, Abivax announced the top-line and subsequent full results of its ABX464 randomized, placebo-controlled phase 2b trial in moderate to severe ulcerative colitis following 8 weeks and 16 weeks of induction treatment. The data confirm the potency of once daily oral ABX464 to maintain and to further improve clinical remission[1] rates over time, across all tested dose levels (25mg, 50mg and 100mg). The sustained and improved effects after 16 weeks of treatment could also be observed for the reduction of the modified Mayo Score[2], the endoscopic improvement[3], the presence of clinical response[4] as well as for the reduction in fecal calprotectin in patients treated with ABX464. This is true for both, the entire population as well as in the subset of patients who were previously refractory to biologic treatments and/or JAK inhibitors.
Consistent with the other clinical studies, ABX464 was found to be safe and well tolerated at all dose levels during the 8-week and 16-week induction period. Within the ABX464 phase 2b induction study, the most frequently reported adverse events were mild and transient (i.e. headache, nausea, gastrointestinal pain) and manageable with or without over-the-counter medication.
Additional laboratory analyses also confirm the novel mechanism of action of ABX464, which fundamentally differentiates this first in-class small molecule from any other drug or drug-candidate in the inflammatory field. It is based on the upregulation of a single physiological microRNA (miR-124), a potent down-regulator of key pro-inflammatory cytokines and chemokines, thereby “putting a brake” on inflammation.[5] A highly statistically significant upregulation of miR-124 could be detected in rectal tissue in all patients treated for 8 weeks with ABX464, compared to baseline. This observation underpins the potential of ABX464 to become a safe short- and long-term efficient treatment option in UC and potentially additional inflammatory indications. In the phase 2b clinical study, 254 patients with moderate to severe active ulcerative colitis were enrolled into the trial and dosed with three once-daily oral ABX464 treatment groups (25mg, 50mg and 100mg) or placebo. 50% of these patients had inadequate response, loss of response, or intolerance to biologics and/or JAK inhibitors treatments while the other 50% were refractory to conventional treatments. Endoscopies were read centrally and blinded by independent reviewers. The baseline disease characteristics were well balanced across all ABX464 dose groups and the placebo group. Enrolled patients suffered from longstanding UC with an overall median duration of 5.45 years and 71.4% of the patients showed a severe disease profile (baseline modified Mayo Score of 7 to 9 points).
ABX464 phase 2b clinical maintenance study in ulcerative colitis
97.7% (217/222) of all patients who completed the phase 2b induction study, irrespective of treatments or treatment outcome during the induction phase, enrolled into the subsequent open-label maintenance study to evaluate the long-term safety and efficacy profile of ABX464 for up to two years. Preliminary results of the openmaintenance study in the first 51 patients after 48 weeks of once-daily treatment with 50mg ABX464 are in line with the previously observed outcomes in the phase 2a study , with 53% (ITT[6]) in clinical remission and 59% (ITT) with endoscopic improvement at 48 weeks (centrally read endoscopies).
In this maintenance study, ABX464 continues to show a good safety and tolerability profile.
Additional phase 2b maintenance results including the first 101 patients who completed 48 weeks of daily treatment with ABX464 will be made public in the late-breaking abstract presentation on October 4, given by Prof. Séverine Vermeire, principal investigator of the study, at the UEG Week Virtual 2021.
ABX464 phase 2a study in ulcerative colitis: Update on ongoing maintenance trial
Abivax recently reported the 3-year efficacy data from its ongoing phase 2a maintenance study in UC. 15 out of the 22 patients who were initially enrolled into the phase 2a maintenance study in 2018, now completed the third year of treatment with 50mg once daily oral ABX464.
Among the 13 patients who underwent centrally read endoscopies at the completion of year 3, 11 patients (85%) were still in clinical remission, among which 7 patients (54%) had an endoscopic remission (endoscopic subscore=0) and 11 patients had an endoscopic improvement (endoscopic subscore=0 or 1).
The long-term safety profile of chronic ABX464 administration continues to be very favorable.[7]
Launch of ABX464 global phase 3 clinical development program in ulcerative colitis
For the launch of its global phase 3 clinical program with ABX464 in UC, Abivax plans to engage in the mandatory consultations with the relevant regulatory authorities. The End-of-Phase-2 meeting with the US regulatory agency (FDA) is expected to occur in Q4 2021. Subject to a positive feedback from the FDA, expected for the end of the year, and the subsequent scientific advice from the European Medical Agency (EMA), planned for Q1 2022, Abivax is planning to start the recruitment and inclusion of the first patients without delay.
ABX464 phase 2a clinical study in rheumatoid arthritis (RA)
In June, Abivax communicated excellent top-line results of the induction phase of its phase 2a clinical study of ABX464 administered in combination with methotrexate (MTX) for the treatment of active moderate to severe RA. 60 patients who had either an inadequate response to methotrexate and/or TNFα inhibitors participated in the study.
The primary endpoint of this study, safety and tolerability, was met with 50mg ABX464 once daily, demonstrating a good safety and tolerability profile in the overall patient population during the 12-week induction phase.
Although the sample size of this study was not powered to show efficacy, the 50mg group already showed statistically significant differences for the key secondary endpoint ACR20[8] compared to placebo at week 12 in the per protocol population. The ACR20is the key primary efficacy endpoint required by the FDA for licensure of new drugs in rheumatoid arthritis.
Following the positive results of the phase 2a trial, entering into the next stage of clinical testing in RA will depend on the outcome of Abivax’s clinical development prioritization.
ABX464 in Crohn’s disease (CD)
Due to the pathophysiological and clinical similarities of CD and UC, Abivax is planning to initiate a pivotal phase 2b study in CD with the objective to demonstrate a similar strong efficacy and favorable safety as already reported in the phase 2a and phase 2b studies in UC.
However, the initiation of the clinical trial in CD will depend on the outcome of Abivax’s clinical development prioritization.
ABX464 phase 1 clinical studies
Abivax is currently conducting four phase 1 studies with ABX464 in healthy volunteers, as part of the usual practice during late-stage clinical drug development. All studies are progressing according to plan. With respect to the phase 1 study conducted in healthy Japanese volunteers, for which Abivax announced the authorization of the Japanese regulatory authorities in August, dosing of the first subject is scheduled for September 28.
The four studies will provide additional data required to support Abivax in seeking approval from the regulatory authorities for its late-stage clinical development program of ABX464, starting with UC.
ABX464 potential market in inflammatory diseases
The inflammatory disease space represents an area of high unmet medical need, and a corresponding substantial market opportunity. In 2020, there were an estimated 3.5M diagnosed cases of ulcerative colitis in G7 countries (US, France, Germany, Italy, Spain, UK and Japan). The total market opportunity for ABX464 is USD 6.0B annually, based on 2020 pharmaceutical sales estimates for ulcerative colitis in these countries. For inflammatory bowel diseases (ulcerative colitis and Crohn’s disease), sales were USD 17.9B in 2020 and are estimated to grow to USD 25.0B by 2025, i.e. the year ABX464 is expected to reach the market for ulcerative colitis.
For rheumatoid arthritis, there were an estimated 3.8M diagnosed cases in G7 countries in 2020. The total market size in RA is USD 20.4B annually, based on 2020 pharmaceutical sales estimates for rheumatoid arthritis in these countries, estimated to grow to USD 22.9B by 2025.[9]
The currently accessible market for ABX464 in IBD and RA is estimated to grow to USD 48B by 2025. The overall chronic inflammation market is estimated to exceed USD 110B at that time.
Prioritization of clinical study programs
Abivax today will further reinforce its focus regarding the launch and conduct of its future clinical trial programs. In order to efficiently allocate and manage the Company’s financial and human resources, the Abivax management and board of directors decided to evaluate the clinical development prioritization for ABX464. The decision, expected in Q4 2021, will be based on market opportunities, market access, product differentiation, clinical development costs, timelines, the probability of success in the US, Europe and Asia and maximizing shareholder value.
ABX196 in hepatocellular carcinoma (HCC)
The phase 1/2 clinical trial in HCC is ongoing at the Scripps MD Anderson Cancer Center in San Diego and the MD Anderson Cancer Center in Houston. In this proof-of-concept study, patients who are failing on checkpoint inhibitors are treated with ABX196 in combination with nivolumab (Opdivo(R), Bristol Myers Squibb). The clinical study consists of two phases, a dose escalation phase, and a subsequent expansion phase.
Currently, the data consolidation of dose escalation phase for which the last patient has been enrolled in June this year, is underway.
Given a positive outcome of the analysis, the Company will decide on next steps, depending on the availability of the required financing or the opportunity of a licensing agreement.
Stopping of ABX464 clinical study in Covid-19 and Bpifrance financing
In March 2021, Abivax announced it would be stopping the phase 2b/3 Covid-19 study (miR-AGE trial – ABX464-401) due to lack of efficacy. This decision followed the recommendation of the Data Safety and Monitoring Board (DSMB), based on an interim analysis evaluating data of 305 high-risk Covid-19 patients after they completed the 28-days study period.
Exit conditions of the Bpifrance agreement relating to the funding of this program are being finalized. In total, Abivax and its academic partner CHU Nice are expecting to benefit from a total funding of EUR 22M (EUR 11M in grants for each partner), which would properly cover the dedicated expenses relating to this program.
