LEIDEN, The Netherlands and SEATTLE, March 8, 2011 - ProFibrix B.V., a leader in the development of innovative
products for hemostasis, today announced that it has initiated a prospective,
multi-center Phase II study with its lead product Fibrocaps at up to 20
sites, including major U.S. and Dutch academic medical centers.

Jaap Koopman, CEO of ProFibrix said: "The start of this large
Phase II study in multiple surgical indications is a major milestone in the
rapid development of our lead product Fibrocaps. If, as we expect, this study
confirms the positive results of our first Phase II trial, we anticipate
initiating a pivotal Phase III trial in early 2012, which puts us on track
for a BLA filing early 2013."

About Fibrocaps

Fibrocaps is based on a mixture of two essential blood
clotting proteins, fibrinogen and thrombin, and is a unique dry powder
topical fibrin sealant being developed to stop bleeding during or after
surgery. Fibrocaps is clearly differentiated from existing liquid tissue
sealants and hemostats: it is ready for immediate use, and is stable at room

About the Study

The second Phase II clinical trial of Fibrocaps (FC002) in the
U.S. and Europe builds on the success of ProFibrix's first Phase II study at
a number of European centers, which demonstrated a compelling safety and
efficacy profile for Fibrocaps. The current Phase II trial is a prospective,
randomized, single-blind, controlled study. The study sites include up to 20
major academic and leading private medical centers in the U.S. and Europe.
Apart from measuring overall safety , the primary efficacy endpoint of the
study is the mean time to hemostasis (TTH) of Fibrocaps versus control.
Approximately 130 patients will be randomized across four different surgical
indications: peripheral vascular surgery, spinal surgery, liver resection
surgery and soft tissue dissection. Completion of the study is expected in
the third quarter of 2011.

To allow ProFibrix to conduct the Fibrocaps Phase II clinical
trial in the U.S., the company filed an Investigational New Drug (IND)
application with the U.S. Food and Drug Administration. Following review by
the Agency in December 2010, the IND is now open and ProFibrix has started
enrolling patients at the participating centers in the U.S. and EU. For more
