DETAILED DESCRIPTION OF FORMULATION, ASEPTIC FILLING, LABELING AND PACKAGING

Overview

Receipt of Bulk Drug Substance

Bulk material will be delivered to CBL at least [**] prior to formulation. Upon receipt, the bulk will be stored at [**]. A sample sent with the bulk will be tested as specified in testing requirements. All batch record steps are performed in accordance with Good Manufacturing Practices.

Preparation of Diluent

GA-GAL diluent is prepared within [**] of use by mixing appropriate quantities of [**]. The composition of GA-GAL diluent is listed in Table 4.4-1.

Table 4.4-1. Composition of GA-GAL Diluent (per Liter)

Component	TKT Part Number	Quantity
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]
[**]	[**]	[**]

The diluent is filtered [**] until required. All filters are subjected to post-filtration integrity testing.

Formulation of α-Galactosidase A for Injection, by CBL

The formulation of the Product will be performed in Class [**] conditions.

Only [**]% of the purified bulk will be initially used to ensure that material is available for adjustment in the event that the formulated bulk is too dilute.

Based on the volume and concentration of the bulk and the desired concentration of GA-GAL in the final formulation, the volume of GA-GAL diluent required for addition is determined. An appropriate amount of diluent is added to [**]% of the target final volume. Then [**] is added, the solution is pH adjusted and finally Q.C. tested for concentration and pH.

Sterile Filtration

The formulated bulk drug product is sterile filtered through [**] Filtration is conducted [**] and then the filter(s) is subjected [**]. All filter integrity testing must be completed with acceptable results before the material is released for further processing. CBL maintains a stringent accountability record on all steps of the filtration process.

Aseptic Filling and Sealing

Filling is conducted in a Class [**] room by trained technicians using validated processes for low volume fills. The filling process is performed using an [**]. The weight of fill per vial is set and checked at the beginning of the fill. Additional weight checks are usually conducted at an interval of [**] and on the last vial filled. Weight check vials are identified, isolated as weight checks and noted in the accountability records.

During the filling process each vial is purged [**]. Each vial is then [**]. Upon completion of the fill, a complete product accountability is performed for the filling process. The filled units in labeled trays are transferred to the appropriate storage conditions (2-8°C) awaiting further processing.

Inspection

The batch record includes a ▇▇▇▇ of Materials, Signature Log, and Final Product Accountability. A 100% visual inspection is conducted using a black and white background. Reject samples are classified by CBL. Other defects are also isolated, for example, improper crimps, container flaws, and stopper defects. Approved inspected units are then made available to the labeling group, who are responsible for label accountability, proper labeling, and packaging.

Storage

Upon completion of inspection, all passed units are quarantined and stored at 2-8°C, awaiting final release.

Unit Labeling

The drug product vials will be labeled as follows:

α-Galactosidase A 1 mg/mL Sterile

3.5 mL Lot No.: #####

Caution: New Drug - Limited by Federal Law to Investigational Use

Store at 2-8°C

Transkaryotic Therapies Inc.

▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇

▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ ▇▇▇

Any changes in labeling text as may occur from time to time, must be sent to the attention of CBL a minimum of 6 weeks prior to the anticipated date of manufacture.

Packaging

Upon commercialization, the labeling and packaging will be changed from bulk. All necessary text and specifications will be supplied by TKT prior to that time.

Retain Samples

CBL holds retain samples for commercial products. Retain samples will be invoiced as regular product, but held at CBL under label storage conditions. The number of retains will be determined by the amount of finished product testing required. Usual practice is to retain sufficient samples to perform all of the testing two times. The retained samples will be held for one year past the expiration date of the lot and CBL will properly dispose of such samples for TKT, or return to TKT upon request.

Stability Samples

Stability in its entirety will be the responsibility of TKT. Any samples held by CBL for stability will be subject to a separate agreement.

Manufacturing Batch Record Summary

All operations are governed by a CBL batch record developed exclusively for TKT’s GA-GAL product. The approved batch record is assigned a TKT project number and a unique CBL lot number. These documents detail the preparation of materials (vials, stoppers, closures,

processing materials, and equipment) used in the manufacturing process. The batch record has been approved by Quality Assurance and Manufacturing at TKT along with appropriate approvals from CBL. CBL staff has the responsibility to perform the aseptic processing and related processing to the instructions detailed in the approved Batch Records. CBL has provided TKT the opportunity to review validation data and reports that reflect the processing of components that have intimate contact with the product.

Reference to the environmental monitoring and personnel monitoring is noted along with the actual data. Before proceeding with manufacturing operations, the operation room conditions are verified for temperature and pressure. CBL performs a [**] prior to filtration and [**] prior to filling.

The batch record is designed to include all quality control testing performed at CBL. The batch record references an SOP to the central sample receiving, in-processing testing (pre and post filtration) and final product testing. The documentation references an SOP to a detailed sampling plan for [**]. The final product testing section relates to tests conducted at CBL and other contracted testing facilities approved by TKT. Final [**] testing at CBL includes [**]. A final Certificate of Analysis is presented along with final review and signature by CBL Quality Assurance.

Batch Record Availability

At the completion of all work for each lot, CBL will provide Client with a copy of the completed Batch Production Record including a Certificate of Analysis. The “batch record” is normally complete within [**] after a fill date unless otherwise agreed upon previously. CBL will work in good faith to reduce the time needed for completion of the batch record.

Disposal or Disposition of Product

Remaining bulk product will be refrozen and all inspection rejects will be stored refrigerated. All will be returned to the client.

VALIDATION PROCESSES

CONFIDENTIAL

VALIDATION PROCESS

USP Testing of Raw Materials (Europe, Japan and USP)

Chemicals purchased with the “USP” or “NF” grade are suitable for use in Pharmaceutical products. Under cGMP they need to undergo only identity testing in addition to establishing the reliability of the suppliers analyses at appropriate intervals in order to be released for use in a regulated product. It is sometimes misunderstood by clients that other chemical grades, such as ACS or ▇▇▇▇▇▇▇ gold, which are perceived as superior products by the criteria of purity and strength, are not approved for use as parenterals in humans. For CBL to use non USP/NF raw materials, it is necessary to perform full USP testing on the chemical, thereby certifying that it meets the requirements of USP/NF.

For those chemicals that are not compendial (US Pharmacopoeia), appropriate tests must be identified to assess identity; purity, quality, and strength. At an appropriate time, that testing must be validated according to guidelines from “Validation of Compendial Assays” USP XXIII <1225>. For concentration (strength) the assay validations are needed for CBL to guarantee formulation results. For other assays, the validation can wait until phase III production, or until it is needed for a guarantee of conformance to specifications.

Assay Tech Transfer [Qualification/Validation]

Evaluation of any Compendial or client supplied assay must be made prior to CBL accepting responsibility for its quantitative use. Compendial assays are assumed to be fully validated and require only a demonstration of their applicability to the analyte as formulated. Client-supplied assays, for which full validation exists, may also be used upon demonstration of congruency, usually involving the comparison of data on a single set of samples which have been assayed in both the client’s and CBL’s laboratories. Non-validated assays for use in early stage (up to early Phase II) testing will also require a transfer of technology with direct comparison of samples between laboratories. Technology transfers as described above will require demonstration of accuracy, precision, ruggedness and linearity. Later stages of the drug approval process require validated assays. If called upon to validate an assay, CBL will follow the guidelines of USP XXIII <1225>. Assays for use in stability programs must be validated regardless of stage of drug development and must be shown to be stability indicating.

Assay tech transfers will be required for [**]

Bacteriostasis / Fungistasis (for Product)

B/F is required in order to establish the potential of the formulation to interfere with sterility assays. B/F testing can be performed on developmental batches as long as they are prepared with GNP material which meets specifications for incoming raw material and have the same formulation as will the GNP batches.

Enhancement / Inhibition (for Product)

E/I evaluates the potential for interference by the formulation with the assay used to measure endotoxin. A preliminary E/I determination will be required to allow quantitation of endotoxin in developmental batches. Full validation of E/I is required once preparation of GNP batches begins. Validation involves performing E/I on three consecutive batches.

Filter Function/Compatibility Study

All materials have some affinity for filter media. In some instances, that affinity is sufficient to cause concern about the ability to filter product and maintain concentration through the process. A successful study is one in which no significant differences are observed when comparing the drug product pre and post filtration. These results help to assure the concentration of product after filtration. This is particularly a problem with biological products and products with very low concentrations.

Cleaning Recovery Study

Contract manufacturers must be able to assure themselves, their clients, and the FDA that no significant chance exists for cross contamination to occur among products sharing equipment which may conceivably contact product. While the interior of the lyophilizer (for example) is certainly not designed to be a product contact surface, the possibility that product may reach the lyophilizes shelves and be dried down on them does present a potential for contamination from a dislodged fragment of some previous client’s product. CBL requires demonstration that products are easily removed from glass or stainless steel surfaces (as appropriate) by the routine cleaning methods called for in CBL cleaning procedures. The cleaning study involves spotting product onto a stainless steel coupon or tray and simulating the method for cleaning the inside of the lyophilizer. Recovery of the product from a stainless steel surface and evaluation of cleaning are monitored by TOC (Total Organic Carbon) analysis which, while lacking the specificity of methods such as BPLC, compensates by virtue of its sensitivity. The cleaning study is expected to demonstrate removal of product from the steel surface. While a negative result is not expected, such a result would require additional evaluation of the data obtained and close consultation with the Client regarding the ability of CBL to proceed.

Equipment Cleaning Validation

Three successive successful demonstrations.

To validate the ability of CBL to prevent cross contamination from Client product, three successive successful demonstrations of effective cleaning of product contact equipment will be required. Collection of each data set will occur after an actual manufacturing event with GMP product. Technicians will sample predetermined sites within the equipment for TOC. The most common equipment for Cleaning Validation are tanks and Pump contact parts. CBL attempts to use as much virgin equipment as possible in order to reduce the need for rigorous and extensive cleaning validation.

Product Hold Time Studies:

The most efficient way to schedule formulation and fill is to do the formulation on the day prior to the fill. A holding study allows CBL to demonstrate that the product will not be adversely affected by holding it for 12-48 hours at cold room conditions with or without an initial filtration to lower bioburden. Bench scale batches will be formulated, treated and stored according to a standard protocol. Potency and other properties which might be, affected by storage will then be analyzed.

Filling Machine Fill Volume Qualification

CBL will perform a fill volume study with the actual product (or placebo) to assure machine process capability. This study will set the target volume for the fill using volume specifications or label data for the product. Typically, a minimum alert level is set at +3 sigma from the target weight for the fill volume. The specification is then set slightly outside of those alert levels.

Filter Extractables Study

This is an FDA requirement for phase III. Product is filtered and the effluent is assayed for known extractable substances. For a purely aqueous product, it is normally not of any consequence. It is typically performed by the filter manufacturer.

Microbial Retention Study

Subcontracted to Millipore. Laboratory testing is conducted with specific pharmaceutical biopharmaceutical product using a standard protocol using B. diminuta grown in saline lactose broth. These experiments are run at room temperature for less than 24 hours on 47 mm disk membranes with less than 20 liters of solution. Microbial Retention Validation is performed to validate microbial retention of sterilizing-grade membrane filters with specific pharmaceutical preparation. Microbial retention testing was recommended by the US Food and Drug Administration’s 1987 “Guideline on Sterile Drug Products Produced by Aseptic Processing” to validate sterilizing-grade membrane filter performance. Under worst case process conditions, the testing determines the ability of a sterilizing-grade filter using scaled-down processing conditions to retain a minimum challenge of 10 cells of B. diminuta per cm2 of filter area. A sample of one drug product lot is evaluated using filters from three manufacturing lots. Initial testing determines whether the sample drug product inhibits the microbial challenge prior to conducting the microbial retention studies. This initial testing will determine the mode of the final testing, ie., whether it is performed in the presence or absence of the product.

Validation Package for BLA

In support of product approval applications, CBL maintains Master Files at FDA for both its Seton and Camden facilities. Clients may request letters authorizing FDA to review CBL’s file in support of their regulatory application (e.g., NDA, ANDA, BLA).

The file contains pertinent information on building and facilities, overall manufacturing operation flow patterns, equipment locations, component sterilization validations (e.g. oven and autoclave loads), action concerning product when media fills fail, details of the environmental monitoring program (viables and non-viables), initial vial and stopper washing validations and utility system validations such as production of water for injection and distribution, clean steam production and distribution, and HVAC systems validations.

Aseptic processing validations are supplied as a summary sheet outlining CBL media fill history.

Finally, the process validation package supplied for the BLA will contain the prospective protocol and the results of the enhanced testing program from the (recommended) three at scale conformance lots. This enhanced testing will be used to demonstrate control of critical manufacturing operations such as mixing uniformity during formulation as well as conformance to production specifications throughout the filling process.
