AC Immune SA (NASDAQ: ACIU), a clinical-stage biopharmaceutical company pioneering precision medicine for neurodegenerative diseases, today announced that it is acquiring Affiris’ portfolio of therapeutics targeting alpha-synuclein (a-syn), notably Affiris PD01, a clinically-validated active vaccine candidate for the treatment of Parkinson’s disease, as well as cash. The all-stock asset acquisition is valued at USD 58.7 million. AC Immune’s cash position, as well as the Company’s investor base, is also being strengthened by a total of USD 30 million in gross proceeds stemming from the asset acquisition and a parallel financing that are adding Athos Service GmbH (Strüngmann family office), First Capital Partner GmbH (Egger Family Office)1 and MIG Fonds2, the lead investors in Covid-19 vaccine innovator BioNTech SE, as new AC Immune shareholders.

Under the terms of the agreement, AC Immune is acquiring all of Affiris’ assets and underlying intellectual property related to active vaccine candidates targeting a-syn and USD 5 million in cash for 7.1 million shares based on a price of USD 8.26 per common share. This share price represents a 10.7% premium compared to the closing price of AC Immune shares as of July 23, 2021.

Concurrent with the asset acquisition, AC Immune announced a private placement transaction with a select group of investors led by Athos Service GmbH with additional participation from First Capital Partner GmbH. Gross proceeds from the private placement will be USD 25 million, based on the same financial terms as for the acquisition of the therapeutic anti-a-syn portfolio. Another lead BioNTech and Affiris investor, MIGoFonds, is also becoming a new AC Immune shareholder via its prior ownership of the anti-a-syn assets acquired. In total, AC Immune is issuing 10.1 million shares in conjunction with the asset acquisition and related financing, in exchange for the aforementioned anti-a-syn assets valued at USD 53.7 million and USDo30 million in cash.

With the support of their new premier investors, who are highly experienced in active vaccination, AC Immune will leverage its own extensive expertise in vaccine development and neurodegenerative diseases to immediately launch clinical development of ACI-7104, the optimized formulation of PD01, into an adaptive, biomarker-based Phase 2 study. This trial will evaluate an initial dose-response of the optimized formulation focusing on immunogenicity against a-syn and pathological a-syn species. Additionally, progression of motor and non-motor symptoms of Parkinson’s disease will be monitored, together with digital, imaging and fluid biomarkers.

Michael Motschmann, General Partner of MIG Fonds, added: "AC Immune is uniquely positioned to successfully advance the industry-leading anti-a-syn vaccine program developed by Affiris and its investors. The program will benefit from AC Immune’s deep expertise in precision medicine and active vaccination approaches for neurodegenerative diseases. We are thrilled to be joining their high-quality investor base and believe this transaction will be of great benefit to our shareholders and the millions of patients suffering from neurodegenerative diseases around the world."

Thomas Strüngmann, Co-Founder of Athos Service GmbH, commented: “We have learned from Covid-19 that collaboration can accelerate the development of safe and efficacious vaccines that can be deployed broadly to deliver highly effective protection for very large populations. This is why we strongly endorse this transaction with AC Immune, a global leader in vaccine development in neurodegeneration with an impressive precision medicine pipeline and record of execution. We look forward to working with the Company to potentially translate what has been done for infectious diseases to neurodegenerative diseases like Parkinson’s and Alzheimer’s.”

Prof. Andrea Pfeifer, CEO of AC Immune SA, commented: “We believe very strongly that active vaccination will play an important role in the long-term management and possible prevention of neurodegenerative diseases. By acquiring a clinically validated vaccine program against a-syn, we are advancing AC Immune to the forefront of Parkinson’s disease drug development, with a wholly-owned a-syn portfolio that now covers a full spectrum of treatment modalities addressing this well-characterized target.”

“We are also proud to welcome three of the foremost investors in vaccine development, the Strüngmann Family’s Athos Service, First Capital Partner GmbH and MIG Fonds, to AC Immune. As the lead investors in BioNTech, they have a globally recognized track record of identifying and supporting successful vaccine technologies. Their support of Affiris and now AC Immune serves as an endorsement of an active immunization approach for Parkinson’s disease, and provides key external validation for AC Immune’s unmatched expertise in the development of vaccines for neurodegenerative diseases.”

Parkinson’s disease is causally linked to pathological aggregation and deposition of a-syn, a drug target that has been validated in clinical studies using monoclonal antibodies. Affiris PD01 is a vaccine designed to generate a target-specific antibody response against pathological oligomeric a-syn. Randomized Phase 1 results published in The Lancet Neurology showed that PD01 generated substantial, long-lasting and boostable antibody responses against pathological forms of a-syn that were accompanied by target engagement and signals of clinical efficacy. These data also showed that PD01 had a favorable safety and tolerability profile. This anti-a-syn vaccine complements AC Immune’s existing portfolio of clinical and preclinical candidates addressing a-syn, which includes an anti-a-syn antibody, a small molecule aggregation inhibitor, and a first-in-class diagnostic imaging agent, which together may enable a precision medicine approach to treating Parkinson’s disease and other alpha-synucleinopathies. With this acquisition, AC Immune becomes a leader in the development of therapeutics and diagnostics for Parkinson’s disease.

AC Immune’s expertise in active vaccine development is based on its SupraAntigen®-V vaccine platform, which has been shown to generate powerful, target-specific, polyclonal antibody responses that are in the range of therapeutic monoclonal antibodies. Earlier this year, the Company reported highly encouraging readouts from its ongoing Alzheimer’s disease vaccine programs targeting phospho-Tau and pathological amyloid beta (Abeta) including the most toxic oligomeric and pyroglutamate Abeta species. With the recent accelerated approval of the passive immunotherapy Aduhelm™ based on Abeta biomarker data and encouraging clinical results for the anti-Abeta antibody donanemab that demonstrate the potential benefit of targeting pyroglutamate Abeta species, AC Immune is positioned to greatly accelerate the potential time-to-market for its optimized Abeta vaccine. AC Immune is leveraging its extensive vaccine expertise to enrich and accelerate the development of ACI-7104 for Parkinson’s disease and other a-synucleinopathies.

The acquisition is subject to customary regulatory approval in Austria and expected to complete at the beginning of Q4 2021.
