                Protalix BioTherapeutics, Inc. Receives Approval
          from the FDA to Initiate a Phase III Clinical Trial of prGCD

                  Phase III clinical trial may commence shortly

Carmiel, Israel - April 18, 2007 - Protalix BioTherapeutics, Inc. (AMEX: PLX)
today announced that it has received written notice from the United States Food
and Drug Administration (FDA) that it may initiate a Phase III clinical trial in
the United States of its lead product candidate, prGCD, a proprietary plant cell
expressed recombinant form of human Glucocerebrosidase (GCD), for the treatment
of Gaucher Disease, a lysosomal storage disorder in humans.

The FDA has allowed the Company to directly initiate Phase III based upon the
results of the Company's pre clinical and Phase I clinical trials of prGCD. The
Company presented the completed data from its Phase I clinical trial at the
European Working Group of Gaucher Disease (WEGGD) in Cambridge, United Kingdom
in July 2006.

The Company hopes to commence the Phase III clinical trial shortly. The trial
will take place in centers in the United States, Israel, where approval from the
Israeli Ministry of Health has been received, and other locations worldwide. The
study will initially consist of male and female adult patients with Gaucher
Disease.

David Aviezer, Ph.D., President and Chief Executive Officer of Protalix
BioTherapeutics, commented, "The receipt of the FDA's approval to initiate a
Phase III clinical trial of prGCD represents an important milestone in the
development of this product, and we are excited about the progress we have made
thus far. Following the success of our Phase I trial and our promising pre
clinical and biochemical data, we believe that we will continue to see positive
results from our patients in Phase III."

Dr. Aviezer continued, "We remain deeply committed to the development of a
treatment for Gaucher Disease and are excited by the opportunity to commence the
Phase III trial and working with the medical experts and patient community."
