FDA Gives Green Light to Phase 2 Trial of NurOwn Stem Cell Therapy in Progressive MS Patients

The U.S. Food and Drug Administration (FDA) has approved BrainStorm Cell Therapeutics‘ request to open a Phase 2 clinical trial testing the safety and effectiveness of its proprietary NurOwn mesenchymal stem cell (MSC) treatment in progressive multiple sclerosis (MS) patients.

The request was in the form of Investigational New Drug (IND) application, and BrainStorm plans to launch the study in early 2019.

“We are excited about the launch of early testing of this cell-based approach to treating progressive MS, for which there are few treatment options,” Bruce Bebo, executive vice president of research at the National MS Society, said in a press release. “We look forward to better understanding the potential benefits and safety of this and other cell-based therapies for MS.”

Stem cells have the ability to develop into different cell types, and to replace damaged or dying cells in the body. There are different types of stem cells, and therapies based on these cells are being investigated for several diseases, including MS.

NurOwn cells are MSCs obtained from a patient’s bone marrow — the spongy tissue inside bones — and grown in the lab under patented conditions in order to induce the cells to secrete high levels of neurotrophic factors (NTF), molecules that support the growth, survival, and differentiation of neurons. These MSC-NTF cells are then injected back into the patient intravenously or into the spinal canal.

Experiments with mice suggest that injected NurOwn stem cells do not themselves replace damaged cells. Instead, the lab treatment customizes MSCs, converting them into biological factories that secrete high levels of NTFs, which in turn encourage neural stem cells to replace damaged cells.
