Berlin, Germany, Cambridge, MA USA, August 28, 2023<\/strong> \u2013 Bayer AG and BlueRock Therapeutics LP, a clinical stage cell therapy company and wholly owned independently operated subsidiary of Bayer AG, announced today details of the positive data from the Phase I clinical trial for bemdaneprocel (BRT-DA01), a stem cell derived investigational therapy for treating Parkinson\u2019s disease. The data were presented at the International Congress of Parkinson’s Disease and Movement Disorders\u00ae<\/sup> in Copenhagen, Denmark.<\/p>\n The study met the primary objective of demonstrating safety and tolerability in all 12 participants in the study\u2019s low and high dose cohorts, with no serious adverse events (SAEs) reported related to bemdaneprocel through one year. There were two SAEs reported that were unrelated to bemdaneprocel, one seizure attributed to the surgical procedure and one COVID case. Both resolved without sequelae. In addition, 18F-DOPA PET imaging scans demonstrated evidence of cell survival and engraftment in both low and high dose cohorts. 18F-DOPA PET imaging is a neuroradiological technique used to visualize and assess dopaminergic activity in Parkinson\u2019s disease.<\/p>\n Secondary exploratory clinical endpoints improved in both cohorts, with participants in the high dose cohort showing greater improvement, as assessed by the MDS-Unified Parkinson\u2019s Disease Rating Scale Part III (MDS-UPDRS Part III) and the Hauser Diary, which are tools used to assess Parkinson\u2019s disease severity in motor symptoms.<\/p>\n \u201cThe data from this Phase I open label study are extremely encouraging\u201d said Claire Henchcliffe, MD, chair of the UCI School of Medicine Department of Neurology at the University of California, Irvine and one of the study\u2019s Principal Investigators.\u202f\u201cWhile this is a small open-label study,\u202fmeeting the study\u2019s primary objective for safety and tolerability along with initial\u202fimprovements seen in clinical outcomes represents a great step forward. The hope now is that these trends continue and translate into meaningful benefit for people with Parkinson\u2019s disease in controlled clinical trials.\u201d<\/p>\n Using the Hauser Diary, which categorizes patients as being in the \u201cON\u201d state when their symptoms are well controlled and in the \u201cOFF\u201d state when they experience a worsening of their symptoms, participants in the high dose cohort showed a median improvement of 2.16 hours in time spent in the \u201cON\u201d state without troubling dyskinesia compared with baseline after one year. Time spent in the \u201cOFF\u201d state showed a corresponding median decrease of 1.91 hours after one year. Participants in the low dose cohort showed a median improvement of 0.72 hours in the \u201cON\u201d state without troubling dyskinesia time compared with baseline and a corresponding median decrease of 1.62 hours in \u201cOFF\u201d state time.1<\/sup><\/p>\n In the high dose cohort, a one-year measurement of the effects of bemdaneprocel using MDS-UPDRS Part III measured in the \u201cOFF\u201d-medication state, showed a median reduction of 13.0 points compared with baseline. The low dose cohort showed a median increase of 1 point.2<\/sup><\/p>\n \u201cThe need for new therapies to help patients struggling with Parkinson\u2019s disease is clear,\u201d said Ahmed Enayetallah, Senior Vice President and Head of Development, BlueRock Therapeutics. \u201cWe are excited to be sharing the results of this Phase I and look forward to advancing bemdaneprocel to the next stage of clinical testing.\u201d<\/p>\n Based on these results, planning is underway for a Phase II study that is expected to begin enrolling patients in H1 (first half) 2024.<\/p>\n \u201cThe standard of care for millions of people living with Parkinson\u2019s disease has only marginally improved in the past decades, and the existing unmet medical need will only become higher due to the growing aging population\u201d, said Christian Rommel, Member of the Executive Committee of Bayer\u2019s Pharmaceuticals Division and Head of Research and Development. \u201cThe positive outcome of this Phase I clinical trial is a clear step forward, and it brings us closer to delivering new treatment options to patients\u201d.<\/p>\n About bemdaneprocel (BRT-DA01) and the Phase I Trial This phase I study is a multi-center, multi-site, open-label, non-randomized, non-controlled study. Twelve (12) subjects received surgical transplantation of 1 of 2 different dose levels of bemdaneprocel cells to the post-commissural putamen bilaterally, and administration of a 1-year immunosuppression regimen. Cohort A (5 subjects) received a dose of 0.9 million cells per putamen. Cohort B (7 subjects) received 2.7 million cells per putamen. Safety and tolerability were assessed at 1 year, along with evidence of cell survival and motor effects. The feasibility of transplantation was also assessed. All assessments will continue over 2 years.<\/p>\n The transplant surgeries were performed by Dr. Viviane Tabar, MD, Chair of the Department of Neurosurgery at Memorial Sloan Kettering (MSK) Cancer Center and Dr. Andres Lozano, M.D., Ph.D., F.R.C.S.C., F.R.S.C., F.C.A.H.S., Neurosurgeon and Senior Scientist, Krembil Brain Institute, University Health Network (UHN), Alan & Susan Hudson Cornerstone Chair in Neurosurgery, Toronto Western Hospital, University Health Network and Chairman of the Division of Neurosurgery at the University of Toronto (UoT). Participants were followed at clinical sites by Dr. Harini Sarva, M.D. at Weill Cornell Medicine, Dr. Claire Henchcliffe, M.D., D.Phil., F.A.A.N., F.A.N.A. at the University of California, Irvine, and Dr. Alfonso Fasano, M.D., PhD., Chair in Neuromodulation and Multi-Disciplinary Care at the University Health Network (UHN) and UoT.<\/p>\n Disclosure<\/strong>: University Health Network (UHN): UHN has institutional financial interests related to BlueRock.<\/p>\n More information about the Phase I trial is available at clinicaltrials.gov<\/a> (NCT04802733<\/a>).<\/p>\n About Parkinson\u2019s disease About BlueRock Therapeutics LP About Bayer Footnotes<\/strong> 2<\/sup>In the version of this press release distributed on August 28, 2023, this section read as follows: In the high dose cohort, a one-year measurement of the effects of bemdaneprocel using MDS-UPDRS Part III measured in the \u201cOFF\u201d-medication state, showed a reduction of 13.0 points compared with baseline.

\n<\/strong>Bemdaneprocel (BRT-DA01) is an investigational cell therapy designed to replace the dopamine producing neurons that are lost in Parkinson\u2019s disease. These dopaminergic neuron precursors are derived from pluripotent stem cells (PSC) that are human embryonic stem cells. In a surgical procedure, these neuron precursors are implanted into the brain of a person with Parkinson\u2019s disease. When transplanted, they have the potential to reform neural networks that have been severely affected by Parkinson\u2019s and restore motor and non-motor function to patients.<\/p>\n

\n<\/strong>Parkinson\u2019s disease is a progressive neurodegenerative disorder caused by the death of nerve cells in the brain, leading to decreased dopamine levels. At diagnosis, it is estimated that patients have already lost 50-80% of their dopaminergic neurons. The loss of these neurons leads to a progressive loss of motor function and symptoms such as tremors, muscle rigidity, and slowness of movement. Even with medication, the symptoms of Parkinson\u2019s disease can fluctuate during the course of the day. According to the Parkinson\u2019s Foundation, more than 10 million people worldwide suffer from Parkinson\u2019s disease, with approximately one million living in the United States. There is no cure and the effectiveness of current treatments decreases over time.<\/p>\n
