Pluristem CEO Issues Shareholder Update on Clinical Programs

CEO Issues Shareholder Update on Clinical Programs

Israel, July 21, 2020 - Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE:PSTI), a leading regenerative medicine company developing

a platform of novel biological products, today issued an update to its shareholders from its Chief Executive Officer and President,

Fellow Shareholders,

this challenging period marked by the ongoing global COVID-19 pandemic, we are continuing to advance our regenerative medicine

product candidates with the aim of improving the lives and health of people around the world. In addition to our clinical programs,

we are also taking an active role in finding an effective treatment solution to COVID-19 complications. We hope and believe that

PLX-PAD may play an instrumental role in overcoming the devastating impact of the coronavirus.

I would like to provide an update on the key clinical milestones and corporate developments for the year to come. We are heading

towards a pivotal year with four clinical readouts, on multiple opportunities for success in advancing PLX product candidates

towards registration with applicable regulatory agencies. The entire Pluristem team is dedicated to success, and I would like

to make sure all of you are aware of important milestones ahead of us.

III Critical Limb Ischemia (CLI) Study

the last few months, we held discussions with the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA)

to reaffirm understandings related to the interim readout of our global pivotal Phase III study of PLX-PAD in CLI. We expect to

announce top line interim data analysis results during the fourth quarter of calendar 2020.

interim process and possible outcomes:

analysis of the interim data will have three possible outcomes: a) an earlier than planned end-of-study may be achieved if the

top line interim data analysis achieves overwhelming efficacy (p 0.01), b) the study may be declared futile if there is no

probability of successfully achieving the primary endpoint on the full data set after enrolling all patients, or c) the study

is in line with the protocol assumptions and considered to be in a promising zone for success. If the third possible outcome results,

Pluristem will continue to enroll patients, and will analyze the data again on the full data set.

the FDA's and EMA's advice and recommendations, the following are the main items implemented in the study design and

the interim readout:

a slowdown in enrollment due to COVID-19, we currently expect the pace of enrollment to accelerate and forecast to complete enrollment

of the study population in the U.S., Europe and Israel by the fourth quarter of calendar 2020. This expectation takes into consideration

the impact of COVID-19 on the access to treatment and follow up sites while maintaining the safety of the patients, as we continue

to follow FDA and EMA guidelines for conducting clinical studies during COVID-19.

III Muscle Regeneration Study following Hip Fracture

our Phase III trial of PLX-PAD in muscle regeneration following hip fracture in the U.S., Europe and Israel, we have enrolled

more than 60% of the 240 patients planned for the study and we expect to complete enrollment by the end of calendar 2020. Top

line results are expected in the third quarter of calendar 2021.

Phase II U.S. study evaluating PLX-PAD in patients suffering from severe COVID-19 complicated by Acute Respiratory Distress Syndrome

(ARDS) is planned to enroll 140 subjects. We continue to open sites in accordance with the changing dynamics of the spread of

COVID-19 in the U.S. In addition, we are finalizing our discussions with Germany's health regulatory agency, the Paul Ehrlich

Institute, in order to launch a study in Europe. Our target is to complete enrollment and to provide top line 28-days follow-up

data on our U.S. study during the fourth quarter of calendar 2020.

I Hematopoietic Cell Transplantation (HCT) Study

Phase I study of PLX-R18 in hematology, specifically for incomplete hematopoietic recovery following HCT, is enrolling patients

in the U.S. and in Israel. Following discussions with our advisory board, we intend to complete enrollment with 20 patients. We

expect to meet this milestone by the end of the third quarter of calendar 2020, and subsequently provide top line results in the

first quarter of calendar 2021.

had approximately $59 million in cash and cash equivalents as of June 30, 2020. We expect that our current resources, together

with the funds expected from the European Investment Bank (EIB), assuming all agreed milestones are achieved, will support our

operations for over three years. We believe this will enable us to complete the development of our current pipeline, with the

goal to bring multiple product registrations both in the U.S. and Europe.

these times of global challenges, we continue advancing our ongoing clinical trials, while keeping our commitment to the health

and wellbeing of all of our stakeholders. We wish all our shareholders, clinical and business partners, employees and patients

good health and resilience at this time.

line interim data analysis results relating to its Phase III CLI study, the belief that the changes in the primary endpoint for

the interim analysis from the Phase III CLI study will enable its study to meet the required endpoints for both the FDA and EMA

and to start discussions regarding filing of a BLA, that it expects to receive the funds from the EIB and, such funds together
