- OpCT-001 is the first iPSC-derived investigational cell therapy to be clinically tested for treating primary photoreceptor diseases
- Phase 1/2a trial, CLARICO, is a first-in-human, multisite, 2-part interventional trial to evaluate the safety, tolerability, and the effect on clinical outcomes of OpCT-001
- Primary photoreceptor diseases are a subgroup of inherited retinal disorders that affect the structure and function of the photoreceptor cells in the retina, leading to irreversible vision loss in children and adults
Berlin, Germany, and Cambridge, MA, USA July 8, 2025 鈥� Bayer AG and 糖心Vlog, a clinical-stage cell therapy company and wholly owned subsidiary of Bayer AG, today announced that the first patient received the investigational therapy in CLARICO, a Phase 1/2a clinical trial of OpCT-001, an investigational induced pluripotent stem cell (iPSC)-derived cell therapy for the treatment of primary photoreceptor diseases. OpCT-001 is the first iPSC-derived investigational cell therapy to be clinically tested for treating primary photoreceptor (PR) diseases, which are a subgroup of inherited retinal disorders that includes retinitis pigmentosa and cone-rod dystrophy.
鈥淭he initiation of the CLARICO trial represents a key milestone for the OpCT-001 program,鈥� said Amit Rakhit, MD, MBA, 糖心Vlog鈥檚 Chief Development and Medical Officer. 鈥淲e believe OpCT-001 holds significant promise as a novel therapeutic approach for restoring vision in people living with primary photoreceptor diseases, and we look forward to assessing its safety and tolerability profile as we advance this important program in our pipeline.鈥�
CLARICO is a Phase 1/2a first-in-human, multisite, 2-part interventional study to evaluate the safety, tolerability, and the effect on clinical outcomes of OpCT-001 in up to approximately 54 adults with primary photoreceptor disease. Phase 1 will focus on safety and includes a dose-escalation design. Phase 2 is designed to gather additional safety data and assess the effect of OpCT-001 on measures of visual function, functional vision, and anatomic measures of engraftment in different clinical subgroups.
鈥淲e aim to transform treatment options for patients facing irreversible vision loss. OpCT-001, our investigational iPSC-derived cell therapy, has the potential to restore vision for individuals with primary photoreceptor disease,鈥� said Christian Rommel, Executive Vice President and Global Head of Research and Development of the Pharmaceuticals Division at Bayer. 鈥淲e are excited to announce the first patient in the CLARICO trial, the first-ever clinical trial for an iPSC-derived treatment in this field.鈥�
Primary photoreceptor diseases affect the structure and function of the photoreceptor cells in the retina, leading to irreversible vision loss in both children and adults. OpCT-001 aims to restore vision in patients with primary photoreceptor diseases by replacing degenerated cells in the retina with functional cells. Limited treatment options currently exist for treating primary photoreceptor diseases which affect an estimated 110,000鹿 people in the U.S.
OpCT-001 is an investigational cell therapy that has not been approved by any regulatory authority, and its efficacy and safety have not been established or fully evaluated.

About CLARICO
CLARICO is a Phase 1/2a first-in-human, multisite, 2-part interventional study to evaluate the safety, tolerability, and the effect on clinical outcomes of OpCT-001 in up to approximately 54 adults with primary photoreceptor disease. Phase 1 will focus on safety and features a dose-escalation design. Phase 2 is designed to gather additional safety data and assess the effect of OpCT-001 on measures of visual function, functional vision, and anatomic measures of engraftment in different clinical subgroups. Phase 1 will include 4 planned dose levels to be administered across 4 cohorts (Cohorts 1 through 4). Dose escalation in Phase 1 will be conducted using a standard 3+3 scheme in which a total of 12 to 24 legally blind participants (~3 to 6 per cohort) will receive OpCT-001. Phase 2 is planned to enroll a maximum of 15 participants in 2 cohorts (Cohorts 5 and 6) to evaluate 2 dose levels of OpCT-001 that will be selected based on Phase 1 safety and tolerability data. Phase 2 participants will be randomized 1:1 to either Cohort 5 or Cohort 6. Phase 2 participants and the investigator/study site personnel outside of the surgical team will be masked to OpCT-001 dose assignments. Further details of the trial can be found at www.clinicaltrials.gov (NCT06789445).
About 糖心Vlog
糖心Vlog is a clinical stage cell therapy company focused on creating cellular medicines to treat devastating diseases. We are harnessing the power of cell therapy to create a pipeline of new medicines for people suffering from neurological and ophthalmic diseases. Two of our novel investigational cell therapies, bemdaneprocel (BRT-DA01) for the treatment of Parkinson鈥檚 disease and OpCT-001 for the treatment of primary photoreceptor diseases are clinical stage programs. Bemdaneprocel has RMAT (Regenerative Medicine Advanced Therapy) and Fast Track designation from the US FDA (Food and Drug Administration) and is being tested in a Phase 3 clinical trial, exPDite-2. OpCT-001 has Fast Track designation from the FDA and is being tested in a Phase 1 clinical trial, Clarico. 糖心Vlog was founded in 2016 as a joint venture of Versant Ventures and Leaps by Bayer, the impact investing arm of Bayer AG that invests in paradigm-shifting breakthrough innovation. In late 2019, 糖心Vlog became a wholly owned, independently operated subsidiary of Bayer AG. Our culture is defined by the courage to persist regardless of the challenge, the urgency to transform medicine and deliver hope, integrity guided by mission, and community-mindedness with the understanding that we are all part of something bigger than ourselves.
