2. SCOPE OF PROPOSAL

2.1 Overview of Deliverables

This stage of the L-DOS47 project will be used to optimize certain process conditions, meet current and future regulatory requirements and provide for 3 × 50 grams of L-DOS47 Conjugate for toxicological studies and phase I clinical trials.

3. CELL BANK STRATEGY

3.1 Deliverables

The research cell bank (“RCB”) that has been used for the project to date at BioVectra will be used for the first and/or second 50 gram lot in this next stage of the project. BioVectra needs to establish the baseline traceability and lineage of the current RCB. The current RCB can be used for this stage based on the availability of pertinent technical details surrounding the origin of the cell bank. In order to meet the current and future regulatory requirements for this process BioVectra will require the documentation listed in Appendix A from Helix to support this strategy (this information can be provided as copies of original records). BioVectra is preparing the process to be future compliant with ICHQ5B.

Once the documentation of the RCB has been reviewed and evaluated BioVectra will use a single vial of the RCB as the working cell bank (“WCB”) for this portion of the L-DOS47 development activities. These activities are summarized below

I.	Determination of the Limit for Cell Age for Production

II.	Microbiological purity trial of the cell bank

III.	Reproducibility trial of the cell bank

IV.	Limited Characterization of the cell bank for use in the production runs

For the remaining 50 gram lots of L-DOS47 a Master Cell Bank (“MCB”) will be prepared and characterized. The work to produce the MCB will need to occur concurrent to the preliminary work outlined in this proposal. BioVectra will utilize their partner CRO to prepare and test the cGMP MCB. This proposal includes the cost to prepare 100 vials of the MCB and perform the characterization tests itemized below. The vial stock will be stored at BioVectra as well as an alternate controlled site. The cost for this storage is included in the proposal.

Master Cell Bank Characterization tests:

·	Purity via differential agars

·	Microbial ID by comparative sequence

·	Analysis of genomic DNA

·	Viability of Bacterial suspensions

·	Mytomycin C

·	Retention of selectable markers

·	Retention of recombinant construct

·	DNA sequencing

·	Analysis of gene copy number by PCR

·	Restriction endonuclease analysis – confirmatory assay

3.1.1 Determination of the Limit for Cell Age for Production

This is a requirement by ICH5B as well as a pertinent study performed to ensure that the cell line will carry the plasmid through to the age required for the production fermentor. The limit for in vitro cell age for production will be derived from production cells expanded under pilot-scale conditions to mimic the production in vitro cell age or beyond. This will be accomplished by expanding the cell line from vial to shake flask to 30L fermentor and again to the 30L fermentor (using equivalent inoculum) to mimic the future production age in the 500 L fermentor. This study has also been referred to as a plasmid stability test.

At this point the production cells will be examined using different dilutions on both selective and non-selective agars to determine the purity and plasmid retention of the production cells at this stage. Viability can also be determined at this point. It is recommended to expand the cell age past the planned production age to justify expansion of cell line to a later age (i.e. larger scale) that might be required in the future of the L-DOS47 development. The expression construct of the production cells at this cell age will also be analyzed at this point. The protein coding sequence of the expression construct in the production cells will be verified by nucleic acid testing or analysis of the final protein product. This will provide assurance that at the next planned production scale (500L) the cell line has the ability to produce comparable results as those established at the 20L scale (or age). Through this study, BioVectra will be able to establish an acceptable level of plasmid loss or protein titer that can be applied as an acceptance specification for later development batches.

3.1.2 Microbiological and Reproducibility Trial

To assure the microbiologic purity of the cell bank that will be used for the production of the clinical material, a trial must be performed to check for external contamination. Using the culture in production for determination of the limit for cell age (3.1.1) a sample will be taken for a microbiological trial (“MT”) prior to the addition of the inducer. External contamination will be checked using different agar medium plates (with and without antibiotics). Colony characteristics will be verified to determine purity at this cell age, which will indicate purity of the originating cell bank.

Using the same fermentation culture the reproducibility of the cell bank will be determined. The end point is similar to the limit for cell age except that the titer of the AFAIK2 is of specific interest. A sample will be taken at the end of the fermentation in the 30 L fermentor and taken to a certain point in the downstream process to determine titer. A target titer specification can then be applied to the cell bank, based on the titer obtained in the reproducibility trial. We have previously used a target titer that is approximately 50% of the typical production titer.

3.1.3 Limited Characterization of the RCB

Depending on the detail of the documentation provided by Helix in Appendix A, a limited amount of testing will be performed to provide additional data for the RCB that will be used for the production scale work. This work will be performed as pre-bank confirmatory testing prior to the creation of the MCB and not as a release test for the RCB. These tests will include,

I.	Induction of Bacterial virus from E.coli using Mytomycin C. This will determine if the cell bank is lysogenic in nature or contaminated with phage.

II.	Determination of purity in differential agars

III.	Microbial ID by comparative sequence analysis

This testing will be performed by BioVectra’s partner CRO and the cost is included in this proposal. Helix will be provided with a summary and copies of the primary data for review.

4. PRE-PILOT SCALE DEVELOPMENT

4.1 Option A

The use of a different protein source is an option at this point in the development of the AFAIK2 fermentation. If investigation of an alternate protein is desired, prior to scaling the fermentation to the next stage a certain number of activities will need to be undertaken to assure the process for the production of AFAIK2 at the 500L scale will support the current stage of the project. These activities are summarized below,

I.	Replacement of the LB media with another protein source at shake flask

II.	Testing of a new agar medium

III.	New media test fermentation at 30L fermentor scale

4.1.1 LB Media Replacement

Previous investigations using a chemically defined media did not meet yield expectations, a study will be undertaken to test new animal free media protein sources at the shake flask scale. The determining factor for choosing a new media component will be relative growth rate as compared to the control LB media. At the present time HySoy, Yeast extract, HiVeg, HiPep, HiYeast, Amisoy and Celton are being looked at as replacement media.

4.1.3 Pilot Fermentation(s) Utilizing New Protein Source

To confirm the results obtained at the shake flask stage, a pilot scale fermentation of the AFAIK2 will be performed at a 30L fermentor scale. These runs will also serve as technical transfer runs to qualify a disk stack centrifuge to be used in the process for cell separation as well as further optimize and scale up the use of the microfluidizer for cell lysis. The downstream processing will be taken to such a point where BioVectra can confirm comparable AFAIK2 purity to the batches prepared using LB media. Additional improvements for the DSP portion of the process can be studied using these runs to supply product (i.e. addition of protease inhibitors). The fermentation parameters confirmed in this batch will be used to prepare the protocols and batch records for the 500 L scale.

4.2 Option B

The use of the chemically defined R media requires additional development and optimization of the titer and purification yield for the AFAIK2. This is based upon the results of the two 20L fermentation trials performed to date. Prior to scaling the fermentation to the next stage there are a certain number of activities that must be undertaken to assure the process for the production of AFAIK2 at the 500L scale will support the current stage of the project. These activities are summarized below,

I.	Repeat the R media shake flask experiments

II.	R media test fermentation at 20-30L fermentor scale

III.	Purification of AFAIK2 to confirm yield from 20-30L scale.
