Pluristem Expands its Compassionate Use Program: Treated First COVID-19 Patient in U.S. Under FDA Single Patient Expanded Access Program

• Cleared by FDA to proceed with the treatment in U.S. under Coronavirus Treatment Acceleration Program (CTAP)
• Pluristem’s main focus: multinational clinical trial of PLX cells for treatment of complications associated with COVID-19

HAIFA, Israel, April 13, 2020 (GLOBE NEWSWIRE) -- Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE:PSTI), a leading regenerative medicine company developing a platform of novel biological therapeutic products, announced today that it has treated its first patient suffering from COVID-19 complications in the United States under the U.S. Food and Drug Administration’s (FDA) Single Patient Expanded Access Program, also called a compassionate use program, which is part of the U.S. Coronavirus Treatment Acceleration Program (CTAP), an emergency program for possible therapies that uses every available method to move new treatments to patients as quickly as possible.

The patient was treated with PLX cell therapy at Holy Name Medical Center in New Jersey, an acute care facility that is currently an active site for Pluristem’s Phase III critical limb ischemia (CLI) study. Prior to treatment with PLX, the patient was critically ill with respiratory failure due to acute respiratory distress syndrome (ARDS) and was under mechanical ventilation in an intensive care unit (ICU) for three weeks.

“We are receiving many inquiries and requests for treatment from healthcare providers and families worldwide. In parallel with our planned clinical trial, we expect to continue treating patients under compassionate use through the appropriate regulatory clearances in the United States and Israel, as well as expanding treatment under compassionate use in other countries. Our main focus remains however, the initiation of a multinational clinical study,” stated Pluristem CEO and President Yaky Yanay.

Pluristem’s main target is to initiate a multinational clinical trial as soon as possible for PLX cells in the treatment of patients suffering from complications associated with COVID-19. As the Company focus is the initiation of such clinical trial, it does not intend to provide further updates on the status of patients treated under compassionate use. Pluristem will update on the status and progress of its planned COVID-19 clinical trial program.

PLX Cells for COVID-19
PLX cells are available off-the-shelf and once commercialized, can be manufactured in large scale quantities, offering a key advantage in addressing a global pandemic. PLX cells are allogeneic mesenchymal-like cells that have immunomodulatory properties that induce the immune system’s natural regulatory T cells and M2 macrophages, and thus may prevent or reverse the dangerous overactivation of the immune system. Accordingly, PLX cells may potentially reduce the incidence and\or severity of COVID-19 pneumonia and pneumonitis leading hopefully to a better prognosis for the patients. Previous pre-clinical findings of PLX cells revealed therapeutic benefit in animal studies of pulmonary hypertension, lung fibrosis, acute kidney injury and gastrointestinal injury which are potential complications of the severe COVID-19 infection. Clinical data using PLX cells demonstrated the strong immunomodulatory potency of PLX cells in patients post major surgery. Taken together, PLX cells’ potential capabilities with the safety profile observed from clinical trials involving hundreds of patients worldwide potentially position them as a therapy for mitigating the tissue-damaging effects of COVID-19.
