APPENDIX B
Project Plan
UK Bovine Vaccine Project Plan for Phase I Formulation Development

PROJECT OBJECTIVES AND SCOPE

The goal of this project is to develop a rotavirus formulation using GRAS (Generally Regarded as Safe) ingredients that is superior to the current dosage formulation currently being used which is a single dose lyophilized formulation stored at 2-8°C reconstituted with liquid antacid (citrate and bicarbonate). The criteria for success are defined as follows:

· Stability: A vaccine formulation that is stable when stored at 2-8°C for at least one year with 0.5 log FFU/dose per serotype is desirable and should be the goal of project. However if the new formulation has superior attributes to the current lyophilized formulation that enhanced commercial acceptability (e.g. stable at higher temperatures, supports a less expense delivery device, etc.) then virus loss> 0.5 log FFU/dose per serotype may be acceptable.

· Buffer: A successful formulation will contain sufficient amount of antacids to buffer against stomach acids and transit through to the gut.

· Cost effective: The manufacturing process for a successful formulation must be implementable at commercial scale in a developing world manufacturing setting.

· Intellectual property: A successful formulation will not infringe any other patents (prior art for rotavirus vaccines).

· Vaccine serotypes studied: A successful formulation must work with UK x Human reassortants for Serotype G1, G2, G4 and G9.

Project execution

Phase I is anticipated to be approximately 18 months in duration. At the completion of Phase I, Aridis will present to PVS and the UK bovine rotavirus vaccine (BRV) manufacturing partners the liquid and powder blend formulations Aridis believes meets the goals of the project. If sufficient data are available that demonstrates one or more formulation options to be superior to the existing formulation, PVS will decide whether to authorize Aridis to continue formulation development (Phase II) in cooperation with the BRV manufacturing partners and a delivery device/packaging company. This phase will evaluate delivery devices for the new formulations.

A superior formulation will include one or more of the following:

· Buffer and vaccine together in one formulation

· Any formulation that is liquid stored at 2-8°C

· A formulation that lends itself to a more convenient delivery device

· A formulation that leads to a cheaper delivery device

· A formulation process that is determined to be less expense than lyophilization in terms of capital expense or unit cost

· Increased stability resulting in less virus needed at the time of formulation

· Increased stability at temperatures above 25°C

Project milestones and work plan

(All time periods originate from the date Aridis receives materials from PVS to initiate formulation activities)

Liquid Formulation

Month 0- 4		Develop a multidimensional phase diagram using high throughput appropriate analytical tests (possible methods include high resolution 2nd derivative UV spectroscopy, intrinsic and extrinsic fluorescence spectroscopy, circular dichroism, and dynamic light scattering) to map the pH, ionic strength, and temperature regimes where the vaccine is most physically stable. These analytical tests will define solution conditions that avoid viral aggregation, protein structural changes, membrane changes, disassembly, etc. that are potential pathways leading to poor storage stability. Data provided to PVS at the completion of this milestone. If the data from these studies demonstrate that virus serotypes other than G1, G2, G4 and G9 be evaluated in subsequent studies or additional data is obtained from other sources, Aridis and PVS will work together to make the necessary adjustments in the virus serotypes evaluated.

Month 4 and 5		Select excipients, formulations, and additives to develop a refrigerator stable liquid formulation. Stabilizer classes that have been successfully used previously include non- reducing polysaccharides (sucrose, trehalose, etc.), synthetic polymers and biopolymers (hydrolyzed gelatin, polyvinyl pyrrolidone, etc.), small charged amino acids (arginine, lysine, etc.) and surfactants (pluronics, Tweens). Candidate antacids (citrate, sodium bicarbonate, etc.) will also be screened together with stabilizers. The stabilizers selected and formulations to be studies provided to PVS.

Month 6 to 11		A minimum of 15 formulations combinations will be tested using monovalent vaccine preparations of G9 and G1 serotype viruses for stability under 2-8°C, and 25°C (accelerated) storage conditions.

Month 12 to 17		Up to 5 lead formulation candidates will be tested as a tetravalent vaccine consisting of G1, G2, G4 and G9 for stability under real-time at 2-8°C storage condition.

Month 18		Present final results to PVS on lead candidate.

Powder Formulation

Month 0-1		Review data from PVS on the Wyeth powder blend formulation process.

Month 2 to 4		Prepare spray dried and bulk lyophilized preparations of two rotavirus serotypes, G1 and G9 serotypes. Prepare antacid buffer salts.

Month 5 to 6		Prepare powder blends of bivalent virus with and without antacid buffer salts for stability evaluation under l 5°C, and 25°C (accelerated) storage conditions.

Month 7 to 10		Evaluate the stability of all 4 powder formulations: Gl/G9 bulk lyophilized; Gl/G9 spray dried; Gl/G9 with buffer salts; Gl/G9 without buffer salts.

Month 11 to 13		Prepare a tetravalent powder blend (G1, G2, G4 and G9) using one manufacturing process (spray dried or bulk lyophilized) and evaluate stability at 2-8°C.

Month 18		Present the manufacturing process and stability data to PVS.

Materials to be provided by PVS (or through its designee):

1. 5 liters of post filtered monovalent bulk of serotypes G1, G2, G4 and G9 and 50 ml of G3 and GS stored at -70°C from Shantha, Biotech. If more vaccine bulks is needed, Shantha Biotech will supply to Aridis upon request.

2. 1ml of 1:100 dilution of monoclonal antibodies to G2, G3 and 20 vials of 1 ml each of G1, G4. Reagent supplies for GS and G9 will be determined later by PVS. If more reagent is needed, PVS or its affiliates will supply to Aridis upon request.

Deliverable at the end of Phase I

Aridis will provide PVS with an abbreviated technology transfer package of sufficient detail to allow a third party to implement the final liquid and powder formulation which has demonstrated to be an improvement over the existing formulation. Aridis will also provide in this abbreviated technology transfer package all stability data used to support the formulation selected for Phase II as well as data from formulations that were not selected. The written package will include the raw materials and solutions that were used in the final formulations studies, a brief description of the manufacturing process, any special equipment used in the formulation; unique facility requirements; process flow diagrams, process operating ranges such as mixing times, temperature conditions, etc. needed to prepare the formulation. All of the above information will

be provided on the formulation or formulations that Aridis and PVS agree warrant further development.

For clarification, the Phase 1 program comprises formulation development and stability testing but not process optimization or scale-up, and the abbreviated data package is not expected to be a manufacturing grade technology transfer package sufficient to allow third party manufacture without further development. Such manufacturing process, process flow and process operating ranges as are developed per this Project Plan - in addition to formulation and stability data - shall be shared.

Formulation, stability and other related data regarding formulations other than the Primary Formulation and Optional Formulation may be provided in summary form.

Scope of Work for Phase II Formulation Development

Prior to commencement of Phase II of the Project Plan, the Parties will develop a mutually agreeable Phase II Project Plan in accordance with the following objectives:

There are two objectives of the Phase II formulation development proposal: First, to continue the development at Aridis of a single formulation selected from the Phase I development program (either liquid or powder blend formulation) in sufficient detail to allow for a smooth transfer of the formulation technology to the developing country rotavirus vaccine manufacturer. Second, to work closely with PVS in selecting a contractor to develop a delivery device that is compatible with the formulation selected for Phase II and meets the needs of the developing world manufacturer.

Activities that will be included in the first objective include scale up of the formulation process in sufficient scale to permit the selection of appropriate equipment and identification of raw material suppliers to carry out the formulation process at commercial manufacturing scale. This objective will also include conducting real time stability studies at the recommended storage conditions and one higher temperature for a shorter duration on 3 pentavalent vaccine formulations containing the GI, G2, G3, G4 and G9 serotypes that were produced at a larger scale of production.

The second objective will involve providing samples of the formulation selected to the delivery device contractor. These samples will match as closely as possible to the final vaccine formulation selected for Phase II development except no live virus will be present. The chemical properties, ingredients and concentrations will be provided to the contractor to assist in the development of the delivery device. Aridis will work closely with the delivery device contractor to evaluate minor changes in the formulation that may be necessary to allow the formulation to adapt to the delivery device. Arid is will be expected to conduct stability studies in the delivery device selected, the extent to which will be dependent on the ability of Aridis or a contract manufacturing organization to fill the live virus vaccine formulation into the delivery device selected for development.
