BlueRock Therapeutics Announces First Patient Dosed with DA01 in Phase 1 Study in Patients with Advanced Parkinson's Disease

CAMBRIDGE, Mass., June 8, 2021 /PRNewswire/ -- BlueRock Therapeutics, a clinical stage biopharmaceutical company and wholly-owned subsidiary of Bayer AG, announced today the dose administration for the first patient in a Phase 1 (Ph1), open-label study of pluripotent stem cell-derived dopaminergic neurons in patients with advanced Parkinson's disease (PD). The purpose of the Ph1 clinical trial is to evaluate the safety, tolerability, and preliminary efficacy of DA01 in patients with PD.

"It's both exciting and humbling to be a part of delivering this first-of-its-kind medicine to Parkinson's patients, with the hope of re-innervating the human brain to make profound and lasting improvements to the quality of life for PD patients," said Emile Nuwaysir, Ph.D., President and Chief Executive Officer of BlueRock. "Our objective is to use authentic cells, to have them integrate entirely into the brain and restore lost physiologic function. If successful, this new therapeutic modality could have implications for the Parkinson's community and beyond."

About the DA01 Phase 1 Trial
The initial study site is Memorial Sloan Kettering Cancer Center and Weill Cornell Medical Center, under the guidance of Dr. Sarva, M.D., Principal Investigator (PI). The trial will enroll ten patients at sites in the US and Canada. In this study, subjects undergo surgical transplantation of the dopamine-producing cells into the putamen. The first surgery was performed by Dr. Viviane Tabar, Chair of the Department of Neurosurgery and Theresa Feng Chair in Neurosurgical Oncology at Memorial Sloan Kettering Cancer Center. The primary objective of the Ph1 study 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 the feasibility of transplantation.

Additional sites will be activated at the University of California, Irvine (PI: Dr. Henchcliffe, M.D., D.Phil.), and the University of Toronto (UHN) (PI: Dr. Lozano, O.C., M.D., Ph.D., F.R.C.S.C., F.R.S.C., F.C.A.H.S.).

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. The worsening of motor and non-motor symptoms is caused by the loss of dopamine-producing neurons. At diagnosis, it is estimated that patients have already lost 60-80% of their dopaminergic neurons. Parkinson's disease often starts with a tremor in one hand. Other symptoms are rigidity, cramping and slowness of movement (bradykinesia). Parkinson's disease is the second most common neurodegenerative disorder, impacting more than 7.5 million people, including 1.3 million people in North America.

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 our revolutionary new medicines to the patients who desperately need them.
