Yes, collaborating with big money pharma again. In the meantime Cytodyn (CYDY) has done a trial on the mild to mid group and have just completed a blinded study on severe to critical patients (390) with results to be posted mid-January. No collaboration there even though it has possibly the best results of any therapeutic thus far -- but having to wait for numbers.
They have also now started a trial for what is termed the "long-haulers".

And when they realize that CCR5 is over expressed in the brains of stroke victims, maybe they'll get still another trial opportunity with leronlimab, which is a CCR5 agonist.
I think it's the mother-in-law of one of the execs of CYDY is a stroke victim so they are very aware of it and it in their sights some place.
Leronlimab Shows Early, but Promising Clinical Responses in First Two Patients Recovering from Stroke
VANCOUVER, Washington, Oct. 26, 2020 (GLOBE NEWSWIRE) -- CytoDyn Inc. (OTC.QB: CYDY), (“CytoDyn” or the “Company"), a late-stage biotechnology company developing leronlimab (PRO 140), a CCR5 antagonist with the potential for multiple therapeutic indications, announced today two patients have demonstrated noticeable signs of improvement following treatment with leronlimab (PRO 140) in helping their recovery from stroke.
The most recent stroke patient, a physician in Mississippi, requested leronlimab, which was administered to him under Mississippi’s recently expanded “Right to Try” statute. The physician’s son, commenting on his father, stated, “He is doing good. Yesterday, he received his second treatment. He said he has been feeling better, and he thinks it is working. He said parts of his body and face that have been numb are starting to change/wake up.”
Scott A. Kelly, M.D., CytoDyn Chairman of the Board, Chief Medical Officer and Head of Business Development, commented, “We are encouraged by leronlimab’s potential to help patients recover from stroke and traumatic brain injury. Independent research has concluded CCR5 is upregulated in neurons after stroke, blocking CCR5 induces motor recovery after stroke, and CCR5 antagonism may enhance learning, memory, and plasticity. CCR5 is rapidly becoming an important target for neural repair in stroke and traumatic brain injury. Our recent data that leronlimab crosses the blood-brain barrier with 70-75% receptor occupancy of the CCR5 receptors in the brain (Macaque model) is encouraging for the potential to enhance recovery in stroke and traumatic brain injury and explore a variety of central nervous system pathology.”
A second stroke patient was receiving treatment with leronlimab as part of her therapy for breast cancer. The treating physician noted her partial paralysis was mitigated relatively quickly, which may have been causally related to the posited role of CCR5 in stroke.
Nader Pourhassan, Ph.D., President and Chief Executive Officer of CytoDyn, stated, “Leronlimab’s ability to cross the blood-brain barrier potentially presents numerous opportunities for the treatment of patients suffering from diseases related to the central nervous system. Therefore, we are accelerating the filing of a Phase 2 protocol to evaluate leronlimab’s potential as a therapeutic for stroke recovery. We continue to focus our energies on our most important task of enrolling more patients in our severe-to-critical COVID-19 Phase 3 trial as quickly as possible. In addition to moving forward rapidly to complete our Biologics License Application for HIV, in multiple countries, our extensive plan includes filing a protocol and IND for Phase 2 clinical trials for both stroke and Long Haulers COVID-19 indications. We continue to strongly believe leronlimab has the potential to provide therapeutic benefit to patients suffering from a variety of diseases, and this incredible prospect drives our management team every day. CytoDyn is committed to fulfilling this obligation to patients of the world.”
About Leronlimab’s Ability to Cross Blood-Brain Barrier
The blood-brain barrier (BBB) mediates the communication between the periphery and the central nervous system (CNS). The BBB separates the circulation from the brain. It is a highly selective permeable border of endothelial cells and acts as a metabolic barrier, transport interface, and secretory body. The BBB prevents solutes in the circulating blood from non-selectively crossing into the central nervous system's extracellular fluid where neurons reside. The blood vessels that vascularize the central nervous system (CNS) possess unique functions. The BBB allows precise control of CNS homeostasis. It serves to allow for proper neuronal function and also protects the neural tissue from toxins and pathogens. Alterations of these barrier properties are an important component of central nervous system diseases.
An important recent discovery of leronlimab is the ability to cross the blood-brain barrier to treat diseases where CCR5 antagonism may benefit the central nervous system. In a study of HIV in macaques, it was determined that the administration of leronlimab resulted in approximately 70-75% CCR5 receptor occupancy in the frontal lobes, parietal lobes, and cerebellum. Independent research on CCR5 antagonism in central nervous system pathology has shown promise in various disease processes, including multiple sclerosis, Parkinson's disease, CNS tumors, traumatic brain injury, and stroke recovery.
