In this episode of The Open Loop, Chay Carter is joined by Dr Nandan Lad and Amaza Reitmeier, the executive leaders behind Pharaoh Neuro.
Nandan is a neurosurgeon at Duke and the inventor behind Neurapheresis, while Amaza brings nearly 25 years of leadership experience from Medtronic, including deep experience in brain therapies and DBS.
This is a practical conversation about Pharaoh Neuro’s mission to create a new category in brain care: CSF modulation, or what Nandan describes as “neurodialysis”.
We explore how Neurapheresis could change the treatment pathway for subarachnoid haemorrhage and hemorrhagic stroke by actively filtering cerebrospinal fluid, removing blood and inflammatory material, and helping reduce devastating downstream complications.
We also discuss the company’s clinical data, Series A raise, regulatory pathway, reimbursement strategy, and the broader platform potential across neuroinflammatory conditions.
Key takeaways:
🔹 Why hemorrhagic stroke remains a major unmet need in brain care
🔹 How Neurapheresis works as a closed-loop CSF filtration system
🔹 Why Pharaoh Neuro is building a new therapeutic category, not just a device
🔹 What early clinical studies showed in blood and protein clearance
🔹 How CSF modulation could expand into meningitis, ALS, MS, leptomeningeal disease, and other neuroinflammatory conditions
