Bayer to Advance Two First-Of-Its-Kind Investigational Cell and Gene Therapies for Parkinson's Disease

  • Parkinson's disease is the most common neurodegenerative movement disorder.
  • It impacts more than 10 million people worldwide
  • Bayer is pursuing a two-pronged approach to deliver transformative therapies with one cell and one gene therapy candidate in clinical trials

    BERLIN--(BUSINESS WIRE)--Bayer AG announced today that BlueRock Therapeutics (BlueRock), a clinical stage biopharmaceutical company and wholly-owned subsidiary of Bayer AG, successfully administered the first dose of its investigational pluripotent stem cell-derived dopaminergic neurons, named DA01, to a Parkinson's disease patient in their open-label Phase 1 clinical safety and tolerability study. In parallel a gene therapy investigational program also targeted at providing advanced therapies for Parkinson's disease is driven forward by Bayer's wholly-owned clinical-stage adeno-associated virus (AAV) gene therapy company Asklepios BioPharmaceutical Inc. (AskBio). This program is currently recruiting and evaluating patients in an ongoing Phase 1b clinical study to assess safety and preliminary efficacy.

    The potential of BlueRock and AskBio's clinical candidates to treat Parkinson's disease and truly help patients with their high unmet medical need could be immense,” said Wolfram Carius, Head of Cell and Gene Therapy at Bayer. “We are still in early phases of clinical trials, but passionately committed to advancing breakthrough science to improve the lives of patients who have been waiting for way too long for innovative treatments.”

    Parkinson's disease is the most common neurodegenerative movement disorder, impacting more than 10 million people worldwide. It is caused by nerve cell (neuron) damage in the brain, leading to decreased levels of dopamine (a neurotransmitter involved in processes such as memory or movement). The disease often starts with a tremor in one hand. Other symptoms include rigidity, cramping and dyskinesias (involuntary, erratic, writhing movements of the face, arms, legs or trunk). Dopamine substitutes, such as levodopa, are commonly used to mitigate the symptoms of the disease, but their effect diminishes as the disease progresses and there is currently no disease-modifying treatment available. By targeting the disease at its root cause, cell and gene therapies aim to go beyond symptomatic treatments.

    Using authentic dopaminergic neurons, BlueRock aims to re-innervate the affected regions of the human brain and reverse the degenerative process, potentially restoring motor function. BlueRock's clinical trial will enroll ten patients at sites in the United States of America (US) and Canada. In this study, patients undergo surgical transplantation of the dopamine-producing cells into the putamen, a deep brain structure affected by Parkinson's disease. The primary objective of the Phase 1 study (NCT04802733) is to assess the safety and tolerability of DA01 cell transplantation at one-year post-transplant. The secondary objectives of the study are to assess the evidence of transplanted cell survival and motor effects at one- and two-years post-transplant, to evaluate continued safety and tolerability at two years, and to assess feasibility of transplantation.

    AskBio's approach consists of an AAV that delivers human glial cell line-derived neurotrophic factor (GDNF) gene to the neurons within the putamen, resulting in expression and secretion of GDNF protein in brain regions impacted by Parkinson's disease. Long-term experiments using AAV-GDNF showed that sustained expression of GDNF can promote regeneration of midbrain neurons and significant motor recovery in rodents and non-human primate models. AskBio's clinical study is currently recruiting and evaluating patients in Phase 1b in the US to assess safety and preliminary efficacy. A total of 10 patients have been enrolled since the start of the Phase 1b study (NCT04167540) in August 2020.

    About BlueRock Therapeutics

    BlueRock Therapeutics is an engineered cell therapy company with a mission to develop regenerative medicines for intractable diseases. The company's cell gene platform enables the creation, manufacture, and delivery of authentic cell therapies with engineered functionality by simultaneously harnessing pluripotent cell biology and genome editing. This enables an approach where, in theory, any cell in the body can be manufactured and any gene in the genome can be engineered for therapeutic purposes. The platform is broadly applicable, but the company is focused today in neurology, cardiology, and immunology. In August 2019, the company was acquired by Bayer AG, for an enterprise value of $1B in upfront and milestone payments. For BlueRock this marks the next step in the journey to prove degenerative disease is reversible, and to bring its revolutionary new medicines to the patients who desperately need them.
