Heidelberg, Germany – July 26, 2023 – AaviGen GmbH, a preclinical stage biotechnology company focused on the development of curative gene therapies for cardiovascular and cardiopulmonary diseases, today announced the completion of its 17M € Series B financing round. Building on AaviGen’s proprietary portfolio of engineered cardiac-specific adeno-associated viral (AAV) capsids, the funding will enable the expansion of its preclinical programs and accelerate its lead gene therapy medicinal product (GTMP) for chronic heart failure towards the clinic. DH-LT Investments GmbH, an investment company led by Dietmar Hopp, commits the financing for the Series B to expand its existing shareholding in AaviGen.

Although current AAV-based gene therapy approaches have shown efficacy in several rare diseases, previous gene medicine developments directed against heart failure were hindered by imprecise targeting and the inability to transduce the heart effectively. AaviGen’s advanced AAV engineering platform is designed to develop differentiated AAV capsids optimized to target the diseased cardiovascular and cardiopulmonary system and to limit transduction of tissues and cell types that are not relevant to the target disease. In executing its lead GTMP program, AaviGen builds on the expertise and track record of its founders and leadership team as well as the experience and commitment of its investor: “Despite the steadily growing prevalence of heart failure, which affects more than 26 million people worldwide, there are essentially no curative therapies available targeting the underlying molecular causes. AaviGen’s therapeutic pipeline aspires to address this critical unmet need. Our highly innovative cardiac-targeted vector generation delivers therapeutic genes against the molecular and genetic foundation of acquired and hereditary heart failure with unprecedented safety and efficacy via a single intravenous injection”, commented Prof. Patrick Most, co-founder, CEO and Managing Director of AaviGen. “We are convinced that AaviGen’s innovative approach to delivering gene medicines to diseased tissues can become a game changer for the gene therapy field. Therefore, we are excited to continue supporting AaviGen in developing its therapeutic candidate for heart failure towards the clinic”, said Dietmar Hopp.

Heidelberg, Germany April 8, 2023 – AaviGen, a preclinical stage biotechnology company focused on the development of curative gene therapies for cardiovascular and cardiopulmonary diseases, announced the completion of its comprehensive cardiac-specific AAV vector development phase. Employing its next-generation Cardiac AAV Platform (next- CAP) that utilizes various human-relevant species, including non-human primates, AaviGen successfully engineered more than 70 proprietary capsids with the desired cardiac tropism and optimally ablated transduction propensity towards non-cardiac organs or tissues (e.g., liver, or dorsal root ganglions).

“We are extremely excited to see the achievements of our versatile cross-species next-CAP platform” said Dr. Martin Busch, COO and head of the R&D team. “Our scientific team has done an exceptional job designing a high-performance experimental/bioinformatic pipeline and successfully executing an elaborate developmental plan that addressed the challenges associated with such a complex endeavor. Our novel capsids have been engineered to target the heart specifically, which is crucial for AAV-based gene therapies that are applied systemically. This targeted approach can be further enhanced with suitable transcriptional control elements, such as cardiomyocyte-specific promoters, to optimize the expression specificity and strength of the therapeutic gene cassette, thereby countering the diverse molecular causes of either acquired or hereditary heart diseases.” Dr. Busch concluded.

Heidelberg, Germany – December 22, 2020 – AaviGen GmbH, a preclinical stage biotechnology company focused on the development of curative gene therapies for cardiovascular and cardiopulmonary diseases, today announced the completion of its initiating 5 million € first financing round. The fundraising adds DH-LT Investments GmbH, an investment company owned and led by SAP co-founder Dietmar Hopp, to AaviGen’s shareholders. The proceeds of the financing will enable the development of precision gene therapies for heart failure, a highly prevalent disease affecting 26 million people worldwide. AaviGen was advised by Mayer Brown LLP, under the lead of Dr. Jan Streer, on the legal aspects of the fundraising.

AaviGen’s lead program employs heart-specific recombinant adeno-associated viruses to bring therapeutic genes with unprecedented ease, safety, precision, and personalization to the diseased heart via a single intravenous injection. In executing its program, AaviGen builds on the expertise and track record of its founders and leadership team as well as the experience and commitment of its investor: “Despite the steadily growing prevalence of heart failure, there are essentially no curative therapies available targeting the molecular causes of the disease. AaviGen aspires to address this critical unmet need with a highly innovative vector engineering technology and gene therapy platform. AaviGen’s new program builds on our experience gained in our late-stage preclinical biotechnology company InoCard”, commented Prof. Patrick Most, co-founder, CEO and Managing Director of AaviGen. “The AaviGen team has proven expertise in advancing scientific innovations in healthcare. I am excited to support AaviGen in launching its development program”, said Dietmar Hopp.
