AskBio Announces First Patient Dosed in Phase 1 / Phase 2 Trial of AB-1003 Gene Therapy for Limb-Girdle Muscular Dystrophy Type 2I/R9 (LGMD2I/R9)

Gene therapy developed to restore FKRP enzyme activity, primarily inside muscle cells, for the treatment of LGMD2I/R9. Research Triangle Park, N.C.– August 3, 2023 – Asklepios BioPharmaceutical, Inc. (AskBio), a gene therapy company wholly owned and independently operated as a subsidiary of Bayer AG, today announced that the first patient has been dosed in the Phase 1 / Phase 2 LION-CS101 clinical trial of patients with limb-girdle muscular dystrophy type 2I/R9 (LGMD2I/R9).[1] AB-1003 (also known as LION-101) is a novel investigational FKRP gene replacement therapy. “Hearing that the first patient has been dosed in this study evaluating AB-1003 is an exciting moment for the limb-girdle muscular dystrophy community and individuals living with this debilitating disease,” said Kelly Brazzo, Co-Founder & CEO, CureLGMD2i. “Given the current lack of disease modifying treatments for LGMD, many in the community know of the potential of gene therapy. The initiation of this trial offers hope that patients with this condition may, in the future, have a significantly improved quality of life.” LGMD2I/R9 is a form of LGMD caused by changes in the FKRP gene and is associated with weakness and wasting of arm and leg muscles.[2]Those with LGMD2I/R9 notice symptoms in late childhood, around 11 years of age, which may include loss of mobility and impaired heart and lung function.2,[3] As symptoms worsen, individuals generally require wheelchairs.2 LGMD2I/R9 is a rare disease, estimated to affect more than 5,000 people in the US and EU.[4] “While the inherited nature of limb-girdle muscular dystrophy means those with the FKRP gene mutation can’t produce a normal FKRP protein for physiological muscle function, AB-1003 is designed to introduce the normal FKRP gene into the muscle and express a normal protein, and it has shown promise in restoring normal FKRP protein function in muscle in preclinical studies performed in mouse models of LGMD,” said Nicholas Johnson, MD, Principal Investigator and Vice Chair of Research at the Department of Neurology, Virginia Commonwealth University School of Medicine. “This trial is the first step toward evaluating the safety of AB-1003 and assessing the potential that AB-1003 has to improve the lives of patients with this serious, inherited ultra rare condition.” “The first limb-girdle muscular dystrophy 2I/R9 patient dosed in the LION-CS101 clinical trial is another example of AskBio’s success in taking gene therapy candidates, such as AB-1003, from the bench into clinical development,” said Jude Samulski, PhD, Co-Founder and Chief Scientific Officer of AskBio. “With our knowledge and expertise, we are working to harness the power of gene therapies as potential treatments for many of the world’s most devastating diseases. Our investigational therapy for limb-girdle muscular dystrophy is one of these and an important part of our portfolio, which also includes clinical stage investigational therapies for congestive heart failure, Huntington’s disease, multiple system atrophy, Parkinson’s disease, and Pompe disease.” AB-1003, which is manufactured by AskBio’s wholly owned and independently operated subsidiary Viralgen, was granted fast track designation by the FDA and orphan drug designation by the European Commission.[5],[6] Recruitment for the LION-CS101 clinical

AskBio to Present Phase 1b Results Investigating AB-1005 (formerly AAV2-GDNF) as Treatment for Parkinson’s Disease at AD/PDTM 2023 International Conference on Alzheimer’s and Parkinson’s Diseases

—Preliminary data suggest that gene therapy via neurosurgical administration is generally safe, well tolerated and associated with enhanced mean putaminal coverage and clinical improvements— —Study uses one-time MRI-monitored surgery for delivery in patients with mild to moderate Parkinson’s disease— Research Triangle Park, N.C.– MARCH 29, 2023 – Asklepios BioPharmaceutical, Inc. (AskBio), a gene therapy company wholly owned and independently operated as a subsidiary of Bayer AG, will present the preliminary results of a clinical Phase 1b study investigating the safety and efficacy of AB-1005, an adeno-associated virus 2 (AAV2) glial cell line-derived neurotrophic factor (GDNF) gene therapy for the treatment of mild to moderate Parkinson’s disease at the AD/PD™ 2023 Advances in Science & Therapy Conference taking place March 28–April 1, 2023, in Gothenburg, Sweden. Initial results from the open-label study investigating AB-1005, administered to the putamen via one-time bilateral convection-enhanced delivery, will be presented during an onsite oral session on April 1 at 5:25 p.m. Central European Time, as part of the “Drug Development in AD, PD, LBD” symposium being held in Hall G3. Preliminary data to be presented suggest that both the gene therapy and the neurosurgical administration are generally safe, well tolerated and associated with enhanced mean putaminal coverage and clinical improvements. The study included 11 participants who had completed 9–18 months of clinical follow-up post treatment, of which 10 had completed more than 12 months. More than 10 million people worldwide are currently living with Parkinson’s disease, which is debilitating and the most common neurodegenerative movement disorder in the world.1,2 Globally, disability and death related to Parkinson’s disease are increasing faster than for any other neurological disorder.3  While GDNF administration has been investigated for Parkinson’s disease for years, results have been mixed. It has been rationalized that by improving GDNF delivery of AAV2 gene therapy with MRI-monitored convection enhanced delivery it may be possible to overcome the limitation of insufficient putaminal coverage to achieve clinical improvements in motor function.4-6 Moreover, clinical trials in Parkinson’s disease over the last decade have shown that AAV is a well-tolerated and suitable vector for gene therapy.7 As leaders in the field of gene therapy, AskBio is committed to investigating the potential that GDNF gene therapy holds for patients with mild to moderate Parkinson’s disease. Although ongoing trials are needed to confirm these findings, the company believes they represent a step forward in advancing therapeutic solutions for those with this debilitating disease. AskBio is also exploring GDNF therapy beyond Parkinson’s and is currently enrolling patients in the US with the parkinsonian subtype of multiple system atrophy (MSA-P) in a Phase 1 trial to assess the preliminary safety, tolerability and efficacy of GDNF therapy for this rapidly progressing condition. ### Media Contact: Phil McNamara Vice President, Corporate Communications, AskBioE: pmcnamara@askbio.com T: +1 984.520-7211  About Parkinson’s Disease  Parkinson’s disease is a progressive neurodegenerative disorder caused by nerve cell damage in the brain, leading to decreased dopamine levels.

Recombinant Adeno-Associated Virus (rAAV) Technology 
Pioneered by AskBio’s Dr. Jude Samulski is Key Component
 of All FDA Approved AAV Gene Therapeutics

Research Triangle Park, N.C. (December X, 2022) – Asklepios BioPharmaceutical, Inc. (AskBio), a wholly-owned and independently-operated subsidiary of Bayer AG, today announced that the FDA’s approval of a new adeno-associated virus (AAV) gene therapy to treat adults with hemophilia B marks another milestone for the advancement of AAV therapeutics and highlights the important research contributions made by AskBio Co-Founder, President and Chief Scientific Officer, R. Jude Samulski, PhD. The significance of Dr. Samulski’s groundbreaking AAV work is validated by the role his pioneering research and discoveries have played in the development of all currently approved AAV gene therapies and most that are in the clinic. Dr. Samulski’s early discovery of how to clone AAV led to its widespread use as a mechanism to deliver healthy genes to cells, and we believe this is the foundation for AAV genetic medicine as it stands today. “The progress made in gene therapy to date is remarkable,” said Jude Samulski, AskBio Co-Founder, President and Chief Scientific Officer. “It is humbling to see the impact of the research I completed over 40 years ago and how this is accelerating AAV therapeutic development. My ultimate vision, shared by all of us at AskBio, is to make gene therapy more accessible for everyone in need around the world. I believe we will be there soon.” Dr. Samulski led the UNC Gene Therapy Center from 1993 to 2016 and, in 2001, co-founded AskBio, where many advances in recombinant AAV (rAAV) and underlying AAV vector technology were, and are being, made. Since 2017, three AAV gene therapies have been approved for use by the FDA. Research performed at the UNC Gene Therapy Center, and advanced at AskBio, helped pave the way for the development of these therapeutics. Hemgenix®1(etranacogene dezaparvovec-drlb), for hemophilia B, uses the AAV vector with Padua variant R338L; Zolgensma®2(onasemnogene abeparvovec-xioi), for spinal muscular atrophy, uses self-complementary AAV vectors; and Luxturna®3(voretigene neparvovec-rzyl), for inherited retinal disease, uses the original AAV2 capsid. All are based on Dr. Samulski’s pioneering research or on technology that he developed in collaboration with others in the field, as are Duchenne muscular dystrophy AAV therapeutics in clinical development.  “We are incredibly fortunate for Jude’s scientific leadership at AskBio and for his continued contributions to genetic medicine,” added AskBio’s CEO, Sheila Mikhail.  “Every day, we see the faces of the people who are running out of time and can’t wait for answers. It is our responsibility to find solutions. I believe that Jude, our AskBio colleagues and others throughout the industry are providing hope for people with devastating diseases.” AskBio, co-founded by Dr. Jude Samulski and Sheila Mikhail, is a global leader in molecular medicine and serves as a key driver of Bayer’s gene therapy research, manufacturing and clinical advancements. _____________________________________________________ 1Hemgenix is a registered trademark of CSL Behring LLC. 2Zolgensma® is a registered trademark of Novartis AG. 3Luxturna® is a registered trademark of Spark Therapeutics, Inc.
