Pluristem Strengthens Its Manufacturing Competitive Advantage, Presents its First Proprietary Serum-Free Cell Therapy Product

This marketing grade serum-free media enables Pluristem large-scale, highly consistent production with operational independency from third party suppliers

HAIFA, Israel, June 17, 2019 - Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE:PSTI), a leading regenerative medicine company developing novel placenta-based cell therapy products, today announced the Company has developed a serum-free formulation to support the manufacturing of cell therapy products. This serum-free media formulation was developed using Pluristem's deep understanding in cell therapy industrial scale production standards, and the quality methods designed to support implementation in Phase III development and marketing. Achieving thissignificanttechnological challenge enables Pluristem large-scale, highly consistent production with operational independency from thirdparty suppliers for standard serum, an expensive and quantity limited product. PLX-R18 is the first product that Pluristem intends to manufacture using the serum-free media.

Cell therapy products, like Pluristem's PLX cells, are grown in cell culture media, whose particular composition and quality are essential to manufacture a desired cell product. Products manufactured using Pluristem's serum-free media demonstrated comparable potency, quality and cellular composition compared to production that relies on serum-containing media. Pluristem's serum free media formulation supports cell therapy production in both standard two-dimensional cell culture and the proprietary threedimensional bioreactor-based cell culture platform that is unique to Pluristem. In addition, unlike standard cell culture media, which often contain undefined blood derived materials, Pluristem believes that its serum-free media formulation will result in a reduced risk of contaminates.

"Pluristem is in the midst of its final pivotal studies, which we are targeting for marketing approval, and believes that quantity and quality are both vital in manufacturing cell therapies products, so that such products will be accessible to any patient who needs them," said Pluristem chairman and co-CEO Zami Aberman. "We are pleased that in adopting serum-free formulation to grow our cells, Pluristem will elevate the standard of cell therapy production and we believe we will be able to increase our supply volume while, in parallel, shift away from third-party serum manufacturers with limited supply. The evolving industry is attempting to move toward serum-free cell therapy production, and this achievement speaks to the strength of our proprietary R&D and manufacturing capabilities."
