PLX Placental cell products -
Mechanism of Action

PLacental eXpanded (PLX) cells are placenta-derived, mesenchymal-like adherent stromal cells that are expanded ex vivo
and are designed to be administered to patients without the need for tissue or genetic matching. This is possible because
of the cells’ low immunogenicity and immune-modulatory properties. Accumulated data from multiple in vitro and in vivo
experiments indicate that these cells have the capacity to release soluble biomolecules, such as cytokines, chemokines
and growth factors, which act in a paracrine and endocrine manner to facilitate healing of damaged tissue. The secreted
therapeutic factors reach the target tissue through the bloodstream and initiate the healing process, while the cells
remain in the muscle into which they were injected.

PLX-PAD

PLX-PAD cells exhibit regenerative potential due
to their capacity to release factors in response
to chemical distress signals from tissues that
have been damaged by muscle trauma or
inflammation. These therapeutic factors trigger
the body’s repair mechanisms and stimulate
tissue renewal, differentiation and modulation
of immune-mediated inflammation. PLX-PAD
cells also rebalance the immune system, which
plays a central role in the body’s exacerbated and
uncontrolled attack on its own cells and organs
 in autoimmune diseases.

Pluri completed a global Phase III study of
PLX-PAD to treat muscle recovery following
surgery for hip fracture. Pluri is part of an
international consortium led by Charité Berlin,
which plans to begin an investigator-initiated
Phase I/II trial to study PLX-PAD for the treatment of Osteoarthritis (OA) during 2023, funded by the
EU Horizon Europe
program. In addition, an
investigator-initiated Phase I/II trial is being
conducted with PLX-PAD by Tel Aviv Sourasky
Medical Center (Ichilov Hospital) for the
treatment of steroid-refractory chronic graft
versus host disease (cGvHD).

PLX-R18

PLX-R18 cells release a combination of therapeutic proteins in response to a damaged or poorly functioning hematopoietic system, which plays a key role in protection from infection, uncontrolled bleeding and anemia.

PLX-R18 cells release a combination of therapeutic proteins in response to a
damaged or poorly functioning hematopoietic system, which plays a key role in
protection from infection, uncontrolled bleeding and anemia.
PLX-R18 is the first product candidate to successfully use technology to
induce PLX cells with different cytokines to alter their secretion profile prior to
administration. A first in human study to evaluate the safety and exploratory
efficacy of intramuscular injections of PLX-R18 in subjects with incomplete
hematopoietic recovery following HCT received positive results.

PLX-R18 cell therapy was granted an orphan drug designation by the FDA for the treatment of graft failure, incomplete hematopoietic recovery following Hematopoietic Cell Transplantation (HCT) and Acute Radiation Syndrome (ARS). The Orphan Drug Act provides for granting special status to a drug or biological product, to treat a rare disease or condition. The benefits of achieving Orphan Drug Designation include close guidance by the FDA, which may accelerate the path to potential marketing approval, orphan drug grants, tax credits, and 7-year market exclusivity upon marketing approval.

Several studies were conducted via the FDA animal rule pathway in order
to evaluate PLX-R18 as a medical countermeasure for the treatment of the
hematopoietic Acute Radiation Syndrome (ARS), and as a potential prophylactic countermeasure against ARS. The FDA has cleared Pluri’s Investigational New
Drug (IND) application for PLX-R18 in the treatment of ARS. The IND allows Pluri to treat victims who may have been acutely exposed to high dose radiation due to nuclear attack or accident.

Induced and
Engineered
PLX CELLS

PLX-R18 is the first product candidate to
successfully use technology to induce PLX
cells with different cytokines to alter their gene
expression and protein secretion profiles. Positive
data from hematology (HCT) study using PLX-R18
demonstrate feasibility of the cell induction
approach and support indication-specific
enhancement of cell activity. Pluri has a pipeline
of additional induced products in development.
Pluri collaborates with the CRISPR-IL consortium
developing genetically engineered PLX cells tailored
for treatment of indications with unmet needs.
