PARIS, France, April 2, 2024, 8:30 a.m. CEST – Abivax SA (Euronext Paris & Nasdaq: ABVX) (“Abivax” or the “Company”), a clinical-stage biotechnology company focused on developing therapeutics that harness the body’s natural regulatory mechanisms to stabilize the immune response in patients with chronic inflammatory diseases, today announced its 2023 annual financial results, as of December 31, 2023, and provided an update on the progress of its development programs. The financial statements for 2023 have been audited and approved by the Company’s Board of Directors on March 28, 2024, and the financial reports are planned to be filed with the French and U.S. securities regulatory authorities, respectively, on April 5, 2024. The audit procedures on the consolidated financial statements have been performed and the certification report is being prepared by the Company’s external auditors.

The Company will organize a webcast on the 2023 financial results on Monday, April 8, 2024, at 2:30 p.m. CEST (8:30 a.m. EST).

Marc de Garidel, Chief Executive Officer of Abivax, said: “In 2023, Abivax accomplished several major milestones and made significant progress on its ongoing clinical and preclinical projects. Beyond executing one of the top worldwide financing raises in the biotech sector last year, the company implemented a strategy designed to take advantage of obefazimod’s unique and differentiated profile for the treatment of IBD. We believe we built the necessary U.S and European operational infrastructure to conduct the Phase 3 ABTECT program in UC and the planned Phase 2b Crohn’s Disease trial, potentially expanding the long-term use of obefazimod for a large patient population in a field with high unmet medical needs. In 2024, the execution of this strategy is underway by advancing our UC and CD clinical programs and, in parallel, strengthening our pipeline by evaluating a potential combination therapy with obefazimod in UC as well as advancing research on a follow-on candidate. Abivax’s scientific excellence has further been highlighted by several abstracts presented by leading U.S. and European KOLs at major scientific congresses. In addition, we continue to reinforce our Board of Directors after notable changes in 2023 and I am glad to welcome Camilla Soenderby as a new member of the Abivax Board. We are very much looking forward to working with Camilla and to benefiting from her expertise.”

Didier Blondel, Chief Financial Officer of Abivax, added: “The past year was also very successful looking at the trust that our existing and new U.S. and European investors placed in us, reflected in the significant capital raises in 2023. With the successful Nasdaq IPO last year, the largest Nasdaq IPO of a French-listed biotech company, we continue to implement our multi-pronged financial strategy to fund our projects in 2024 and beyond. Abivax has secured more than EUR 500M financing in 2023 and we expect to have sufficient funds to finance our operations into Q4 2025, including through the anticipated release of top-line Phase 3 induction data from the ABTECT program.”

2023 financial highlights (IFRS figures)

• Operating loss increased by EUR 62.6M to EUR -127.4M compared to EUR -64.8M as of December 31, 2022. Operating income, consisting predominantly of Research Tax Credit, was comparable between both financial periods. The increase in operating loss was driven by operating expenses as described further below.
  • Research and development (R&D) expenses increased by EUR 54.9M to EUR -103.2M in 2023 compared to EUR -48.3M in 2022. This increase was predominantly driven by a EUR 45.2M, or 117%, increase in expenses related to:
    • Our UC clinical program, driven by the progression of Phase 3 clinical trials for obefazimod in UC (where Phase 3 clinical trial costs were significantly higher than in Phase 2);
    • A EUR 2.7M increase in expenses related to our Crohn’s disease (CD) clinical program, driven by planning costs incurred for the Phase 2b CD trial; and
    • A EUR 4.5M, or 71%, increase related to the overall expansion of the research and development headcount to support our organizational growth and the issuance of new equity awards to officers and employees in research and development.
  • Sales and marketing (S&M) expenses were EUR -6.4M for 2023. We did not incur any sales and marketing expenses in 2022. These expenses consist primarily of consulting costs associated with market research, re-branding of our company in preparation of our U.S. initial public offering and listing on Nasdaq, as well as an early team build out in preparation for our future sales and commercialization efforts in the U.S.
  • General and administrative (G&A) expenses increased to EUR -22.4M compared to EUR -7.5M for 2022 (excluding the one-time goodwill impairment charge taken in 2022 of EUR -13.6M to ABX196 for the treatment of hepatocellular cancer). This increase was primarily due to:
    • An increase in personnel costs of EUR 11.7M, resulting from the issuance of new equity awards to our officers and employees;
    • Management changes that occurred during the period and an increased G&A headcount to support the expansion of the company; and
    • Increased legal and professional fees and other costs associated with operating as a dual-listed public company.
  • Total number of employees at the end of December 2023 was 61 and significantly increased compared to 2022, due to the implementation of the U.S. and European operational infrastructure.
  • For the year ended December 31, 2023, our EUR -20.4M net financial loss was driven primarily by the following items:
    • Interest expenses of EUR -4.7M relation to borrowings and loans;
    • Non-cash expense of EUR -8.9M in relation to the fair value of our royalty certificates;
    • Non-cash expense of EUR -3.4M related to the derecognition of certain financial liabilities;
    • Non-cash expense of EUR -3.0M in relation to an increase in the fair value of warrant derivatives issued in relation to the Kreos/Claret financing; and
    • Foreign exchange losses of EUR -5.6M (including the EUR -3.2M non-cash impact of the year-end revaluation of USD-denominated cash and cash equivalents);
    • Partially offset by interest income of EUR 2.4M in relation to the invested proceeds from our U.S. initial public offering and listing on Nasdaq and decrease in the fair value of the Heights convertible notes by EUR 3.2M.
  • Cash position (including other financial assets of EUR 9.0M) at the end of 2023 was EUR 261.0M, compared to EUR 27.0M at the end of 2022. The increase was due to a EUR 130M gross equity financing (EUR 123M net proceeds) concluded in February 2023, and two additional structured debt agreements (EUR 27M net proceeds from the first tranches) signed in August 2023. In addition, in October 2023 the Company completed its Nasdaq IPO with gross proceeds of EUR 223.3M.
  • As part of the structured debt financing transaction for a total amount of up to EUR 75M with Kreos Capital and Claret European Growth Capital entered into on August 21, 2023 (the “Kreos/Claret financing”), Abivax proceeded with the drawdown of the second tranche of the Kreos/Claret financing for EUR 25M.
    • This second tranche consists of 25,000,000 senior secured non-convertible bonds with a par value of EUR 1.00 each, which will not be listed on any market;
    • The issuance of the Kreos/Claret non-convertible bonds occurred on March 28, 2024;
    • A variable interest rate of 7.5% European Central Bank Base Rate (MRO) (with a floor at 2.5% and a cap at 4%) applies to such tranche. These non-convertible bonds will be repaid monthly through March 31, 2027, after a deferred repayment of the principal until February 1, 2025.
      

Based on the currently available funds, including the drawdown of the second tranche Kreos/Claret financing described above, Abivax expects to be able to finance its operating cash flow requirements into Q4 2025.

Operating highlights - Ongoing clinical trials

Obefazimod Phase 3 program in UC (ABTECT)

The obefazimod Phase 3 ABTECT program investigating efficacy and safety in adults with moderately to severely active UC is progressing. Recruitment into both induction trials, ABTECT-1 and ABTECT-2, is ongoing in all designated regions.

The ABTECT program is designed for 1,200 UC patients across 36 countries with more than 600 trial sites taking part in the pivotal Phase 3 program that covers North America, Europe, Latin America, and Asia Pacific. Clinical remission is the primary endpoint for the 8-week induction trials as well as for the 52-week maintenance trial (which is week 44 of the maintenance trial).

Anticipated milestones:

• Q4 2024: ABTECT planned enrollment of last patient into induction trials
• Q1 2025: ABTECT planned top-line induction data read-out after eight weeks of treatment
• Q1 2026: ABTECT planned top-line maintenance results after one year of treatment
  

Objectives:

• Obtain robust Phase 3 data for obefazimod in moderately to severely active UC as a potentially differentiated oral treatment option
• Establish obefazimod as a potential first-line advanced therapy for the treatment of UC

Obefazimod 25 mg long-term extension trial in UC

UC patients initially treated with 50 mg of oral, once-daily obefazimod and who completed the Phase 2a or Phase 2b maintenance trials could roll over into a follow-on, open-label long-term extension trial with a reduced dose of 25 mg.

In an interim analysis as of July 31, 2023, of the 71 eligible patients, 63 completed their 48-week visit, with a demonstrated disease control rate (stable or improved Modified Mayo Score) of 84% (53 of 63 patients) with the 25 mg once-daily dose of obefazimod. No new safety signals were detected in UC patients treated up to five years with oral, once daily obefazimod.

Anticipated milestones:

• Q3 2024: New obefazimod UC extension trial read-out after one and two years of continued treatment with reduced dose of 25 mg
  

Objectives:

• Confirm safety and efficacy data of Phase 2 maintenance trials and long-term extension trial interim analysis
• Confirm safety and efficacy results for reduced dose of 25 mg obefazimod for chronic long-term use

Operating highlights - Planned clinical trials

Obefazimod Phase 2b trial in Crohn’s disease (ENHANCE-CD)

The obefazimod Phase 2b clinical trial in moderately to severely active CD is a double-blind placebo-controlled trial, evaluating three obefazimod doses. The CD investigational new drug (IND) application was filed with the FDA and cleared to proceed in Q4 2023. The trial design consists of a 12-week induction period and a subsequent 40-week maintenance period.

In alignment with FDA feedback on the Company’s initial Phase 2a IND application submission, the CD trial design was adapted to be a dose ranging Phase 2b clinical trial. These adjustments to the obefazimod CD clinical program are not expected to have an impact on the overall program budget and projected supplemental New Drug Application (sNDA) submission timeline.

Anticipated milestones:

• Q3 2024: ENHANCE-CD planned start of patient enrollment

• 2H 2026: ENHANCE-CD planned 12-week induction data read-out

Objectives:

• Reproduce obefazimod UC Phase 2 safety and efficacy data for the treatment of CD
  

Operating highlights - Ongoing R&D work

• Obefazimod in combination therapy: Based on its early clinical profile, the formal process evaluating combination therapy of oral and injectable candidates with obefazimod in UC is ongoing in preclinical models. Preclinical data to support decision-making on a combination agent is expected in 2H 2024.
• Obefazimod follow-on candidate selection from miR-124 library: R&D work on potential follow-on drug candidates from Abivax’s compound library is ongoing. Selection of the first follow-on drug candidate to further strengthen the Abivax pipeline is expected in Q3 2024.

Anticipated milestones:

• 2H 2024: Disclosure of preclinical data of obefazimod combination therapy for the treatment of moderately to severely active UC
• Q3 2024: Selection of first obefazimod follow-on drug candidate from Abivax’s miR-124 library

Objectives:

• Strengthen Abivax product pipeline with 1) additional opportunities to use obefazimod in a combination therapy; and 2) additional compounds in the field of chronic inflammatory diseases
  

Congress participation

Abivax participated at all major IBD conferences in 2023 and Q1 2024. The submitted abstracts were accepted by the conference hosts and presented by leading U.S. and European KOLs. The potential of obefazimod to become a safe and long-term effective treatment option in IBD, as well as its novel mechanism of action, gains increasing interest among the scientific community and the industry.

Abivax plans to participate and present at all major upcoming congresses in 2024:
