Schedule 4
Development Plan

Introduction

Scientific background

Fibrinogen is a natural blood protein that plays a pivotal role in blood clotting. It does so by forming a complex network of fibrin polymers made-up of aggregated fibrinogen molecules that stop the bleeding and provide a matrix for cells involved in primary haemostasis.

In addition to supporting in vivo haemostatic plug formation, fibrinogen is also involved in tissue repair and remodeling, tumor growth, infections, inflammation and the immune response,. Fibrinogen occurs in blood in many different forms and shapes. Each fibrinogen variant has unique properties with respect to fibrin polymer formation, interaction with cells and other functions of the fibrinogen molecules

Technology Platform

Profibrix is developing a fibrinogen technology platform that has the potential to create a large number of new customized products based on fibrinogen with healthcare potential.

Three pivotal element of the fibrinogen technology platform are:

•• Structure-function analysis of fibrinogen variants to determine new unique functional properties that creates product development opportunities.

•• Purification and characterization of fibrinogen variants form different sources (plasma, recombinant systems).

•• Formulation of fibrinogen variants and other components into end-products.

Product Development

Product development strategy

Using natural fibrinogen variants as building blocks has major advantages. Products are fully biodegradable and not likely to trigger any adverse response, furthermore, the unique functions of fibrinogen variants may be captured in new innovative products that arc tailor made for specific applications with better properties than present treatments.

Applications for these medical products or devices are found in the areas of haemostasis, tissue engineering, drug delivery and immune therapy.

32

ProFibrix’ product development strategy is based on:

•• Identification of medical needs that can be treated using fibrinogen based products.

•• Selection of the fibrinogen variants with optimal functional properties for the products

•• Establishing a commercially feasible manufacturing process for this fibrinogen

•• Development of a formulation that facilitates end-product use and storage.

Lead Product

Fibrocaps: A dry powder fibrin sealant formulation

ProFibrix is developing an improved formulation for human fibrin sealants that are used as topical haemostats for the treatment of acute, severe bleeding after trauma injury or during surgery. Fibrocaps is based on high quality fibrinogen and thrombin formulated as a dry powder which allows pre-mixing of the active components. The advantages of Fibrocaps are:

••    Ease of preparation and application (particularly on large areas)

••    Enhanced and reproducible efficacy due to improved mixing and homogeneity

••    Stable at ambient temperature stored as a ready-for-use fibrinogen /thrombin blend.

••    Increased viral safety profile

••    Utility in different presentation formats (e.g. bandages)

The product is currently in pre-clinical development and pre-clinical proof of concept in validated animal models will be established in HI 2005. A partner will be sought for the clinical development and market introduction which are expected to be competed in 2006 and 2007, respectively.
