STEPS IN SCALE UP 14 Feb. 2011 Alliance Institute, Hyderabad

Define product economics based on projected market size and
competitive selling and provide guidance for allowable manufacturing costs Conduct laboratory studies and scale-up planning at the same time Define key rate-controlling steps in the proposed process Conduct preliminary larger-than-laboratory studies with equipment to be used in rate-controlling step to aid in plant design 14 Feb. 2011 Alliance Institute, Hyderabad

environmental controls, cleaning and sanitizing systems, packaging and
Design and construct a pilot plant including provisions for process and environmental controls, cleaning and sanitizing systems, packaging and waste handling systems, and meeting regulatory agency requirements Evaluate pilot plant results (product and process) including process Economics to make any corrections and a decision on whether or not to proceed with a full scale plant development 14 Feb. 2011 Alliance Institute, Hyderabad

Why conduct Pilot Plant Studies?
A pilot plant allows investigation of a product and process on an intermediate scale before large amounts of money are committed to full-scale production. It is usually not possible to predict the effects of a many-fold increase in scale. It is not possible to design a large scale processing plant from laboratory data alone with any degree of success. 14 Feb. 2011 Alliance Institute, Hyderabad

A pilot plant can be used for
Evaluating the results of laboratory studies and making product and process corrections and improvements. Producing small quantities of product for sensory, chemical, microbiological evaluations, limited market testing or furnishing samples to potential customers, shelf-life and storage stability studies. Providing data that can be used in making a decision on whether or not to proceed to a full-scale production process; and in the case of a positive decision, designing and constructing a full-size plant or modifying an existing plant 14 Feb. 2011 Alliance Institute, Hyderabad

General considerations
Reporting Responsibility The formulator who developed the product can take into the production and can provide support even after transition into production has been completed R & D group with separate staffing 14 Feb. 2011 Alliance Institute, Hyderabad

2. Personnel Requirement
Scientists with experience in pilot plant operations as well as in actual production area are the most preferable. As they have to understand the intent of the formulator as well as understand the perspective of the production personnel. The group should have some personnel with engineering knowledge as well as scale up also involves engineering principles. 14 Feb. 2011 Alliance Institute, Hyderabad

3. Space Requirements Standard equipment floor space Storage area Administration and information processing Physical testing area 14 Feb. 2011 Alliance Institute, Hyderabad

Administration and information process: Adequate office and desk space should be provided for both scientist and technicians. The space should be adjacent to the working area. 14 Feb. 2011 Alliance Institute, Hyderabad

Physical testing area:- This area should provide permanent bench top space for routinely used physical- testing equipment. 14 Feb. 2011 Alliance Institute, Hyderabad

Standard pilot-plant equipment floor space:- Discreet pilot plant space, where the equipment needed for manufacturing all types of dosage form is located. Intermediate – sized and full scale production equipment is essential in evaluating the effects of scale-up of research formulations and processes. Equipments used should be made portable where ever possible. So that after use it can be stored in the small store room. Space for cleaning of the equipment should be also provided. 14 Feb. 2011 Alliance Institute, Hyderabad

Storage Area:- It should have two areas divided as approved and unapproved area for active ingredient as well as excipient. Different areas should provided for the storage of the in-process materials, finished bulk products from the pilot-plant & materials from the experimental scale-up batches made in the production. Storage area for the packing material should also be provided. 14 Feb. 2011 Alliance Institute, Hyderabad

4. Review of the formula: A thorough review of the each aspect of formulation is important. The purpose of each ingredient and it’s contribution to the final product manufactured on the small-scale laboratory equipment should be understood. Then the effect of scale-up using equipment that may subject the product to stresses of different types and degrees can more readily be predicted, or recognized. 14 Feb. 2011 Alliance Institute, Hyderabad

5. Raw materials:- One purpose/responsibility of the pilot-plant is the approval & validation of the active ingredient & excipients raw materials. Raw materials used in the small scale production cannot necessarily be the representative for the large scale production Why? 14 Feb. 2011 Alliance Institute, Hyderabad

6. Equipment:- The most economical and the simplest & efficient equipment which are capable of producing product within the proposed specifications are used. The size of the equipment should be such that the experimental trials run should be relevant to the production sized batches. If the equipment is too small the process developed will not scale up, Whereas if equipment is too big then the wastage of the expensive active ingredients. 14 Feb. 2011 Alliance Institute, Hyderabad

7. Production Rates:- The immediate as well as the future market trends/requirements are considered while determining the production rates. 14 Feb. 2011 Alliance Institute, Hyderabad

8. Process Evaluation:- Order of mixing of components Drying temp. And drying time Mixing speed Screen size (solids) PARAMETERS Mixing time Rate of addition of granulating agents, solvents, solutions of drug etc. Filters size (liquids) Heating and cooling Rates 14 Feb. 2011 Alliance Institute, Hyderabad

Why to carry out process evaluation???? The knowledge of the effects of various process parameters as few mentioned above form the basis for process optimization and validation. 14 Feb. 2011 Alliance Institute, Hyderabad

9. Master Manufacturing Procedures:- The three important aspects Processing directions Manufacturing procedure Weight sheet 14 Feb. 2011 Alliance Institute, Hyderabad

Master Manufacturing Procedures
The weight sheet should clearly identify the chemicals required In a batch. To prevent confusion the names and identifying nos. for the ingredients should be used on batch records. The process directions should be precise and explicit. A manufacturing procedure should be written by the actual operator. Various specifications like addition rates, mixing time, mixing speed, heating, and cooling rates, temperature, storing of the finished product samples should be mentioned in the batch record directions. 14 Feb. 2011 Alliance Institute, Hyderabad

10. Product stability and uniformity:- The primary objective of the pilot plant is the physical as well as chemical stability of the products. Hence each pilot batch representing the final formulation and manufacturing procedure should be studied for stability. Stability studies should be carried out in finished packages as well. 14 Feb. 2011 Alliance Institute, Hyderabad

GMP CONSIDERATION Equipment qualification Process validation Regularly schedule preventative maintenance Regularly process review & revalidation Relevant written standard operating procedures The use of competent technically qualified personnel Adequate provision for training of personnel A well-defined technology transfer system Validated cleaning procedures. An orderly arrangement of equipment so as to ease material flow & prevent cross- contamination 14 Feb. 2011 Alliance Institute, Hyderabad

Advantages Members of the production and quality control divisions can readily observe scale up runs. Supplies of excipients & drugs, cleared by the quality control division, can be drawn from the more spacious areas provided to the production division. Access to engineering department personnel is provided for equipment installation, maintenance and repair. 14 Feb. 2011 Alliance Institute, Hyderabad

Disadvantages The frequency of direct interaction of the formulator with the production personnel in the manufacturing area will be reduced. Any problem in manufacturing will be directed towards it’s own pilot-plant personnel's. 14 Feb. 2011 Alliance Institute, Hyderabad

Scale up of liquid orals

Liquid orals The physical form of a drug product that is pourable displays Newtonian or pseudo plastic flow behavior and conforms to it’s container at room temperature. Liquid dosage forms may be dispersed systems or solutions. In dispersed systems there are two or more phases, where one phase is distributed in another. A solution refers two or more substances mixed homogeneously. 14 Feb. 2011 Alliance Institute, Hyderabad

Steps of liquid manufacturing process
Planning of material requirements: Liquid preparation: Filling and Packing: Quality assurance: 14 Feb. 2011 Alliance Institute, Hyderabad

Critical aspects of liquid manufacturing
Physical Plant: Heating, ventilation and air controlling system: The effect of long processing times at suboptimal temperatures should be considered in terms of consequences on the physical or chemical stability of ingredients as well as product. 14 Feb. 2011 Alliance Institute, Hyderabad

Formulation aspects of oral liquids

Scale-up of semisolid dosage forms

Semisolid dosage forms
In general, semisolid dosage forms are complex formulations having complex structural elements. Often they are composed of two phases (oil and water), one of which is a continuous (external) phase, and the other of which is a dispersed (internal) phase. The active ingredient is often dissolved in one phase, although occasionally the drug is not fully soluble in the system and is dispersed in one or both phases, thus creating a three-phase system. 14 Feb. 2011 Alliance Institute, Hyderabad

Semisolid dosage forms
The physical properties of the dosage form depend upon various factors, including the size of the dispersed particles, the interfacial tension between the phases, the partition coefficient of the active ingredient between the phases, and the product rheology. These factors combine to determine the release characteristics of the drug, as well as other characteristics, such as viscosity. 14 Feb. 2011 Alliance Institute, Hyderabad

Critical manufacturing parameters
For a true solution, the order in which solutes are added to the solvent is usually unimportant. The same cannot be said for dispersed formulations, however, because dispersed matter can distribute differently depending on to which phase a particulate substance is added. In a typical manufacturing process, the critical points are generally the initial separation of a one-phase system into two phases and the point at which the active ingredient is added. 14 Feb. 2011 Alliance Institute, Hyderabad

Because the solubility of each added ingredient is important for determining whether a mixture is visually a single homogeneous phase, such data, possibly supported by optical microscopy, should usually be available for review. This is particularly important for solutes added to the formulation at a concentration near or exceeding that of their solubility at any temperature to which the product may be exposed. 14 Feb. 2011 Alliance Institute, Hyderabad

Variations in the manufacturing procedure that occur after either of these events are likely to be critical to the characteristics of the finished product. This is especially true of any process intended to increase the degree of dispersion through reducing droplet or particle size (e.g., homogenization). Aging of the finished bulk formulation prior to packaging is critical and should be specifically addressed in process validation studies. 14 Feb. 2011 Alliance Institute, Hyderabad

General stability consideration
The effect that SUPAC changes may have on the stability of the drug product should be evaluated. For general guidance on conducting stability studies, see the FDA Guideline for Submitting Documentation for the Stability of Human Drugs and Biologics. 14 Feb. 2011 Alliance Institute, Hyderabad

For SUPAC submissions, the following points should also be considered: In most cases, except those involving scale-up, stability data from pilot scale batches will be acceptable to support the proposed change. 2. Where stability data show a trend towards potency loss or degradant increase under accelerated conditions, it is recommended that historical accelerated stability data from a representative prechange batch be submitted for comparison. 14 Feb. 2011 Alliance Institute, Hyderabad

It is also recommended that under these circumstances, all available long-term data on test batches from ongoing studies be provided in the supplement. Submission of historical accelerated and available long-term data would facilitate review and approval of the supplement. 14 Feb. 2011 Alliance Institute, Hyderabad

3. A commitment should be included to conduct long-term stability studies through the expiration dating period, according to the approved protocol, on either the first or first three (see section III-VI for details) production batches, and to report the results in subsequent annual reports. 14 Feb. 2011 Alliance Institute, Hyderabad

The Role of In Vitro Release Testing
The key parameter for any drug product is its efficacy as demonstrated in controlled clinical trials. The time and expense associated with such trials make them unsuitable as routine quality control methods. Therefore, in vitro surrogate tests are often used to assure that product quality and performance are maintained over time and in the presence of change. 14 Feb. 2011 Alliance Institute, Hyderabad

A variety of physical and chemical tests commonly performed on semisolid products and their components (e.g., solubility, particle size and crystalline form of the active component, viscosity, and homogeneity of the product) have historically provided reasonable evidence of consistent performance. More recently, in vitro release testing has shown promise as a means to comprehensively assure consistent delivery of the active component(s) from semisolid products. 14 Feb. 2011 Alliance Institute, Hyderabad

An in vitro release rate can reflect the combined effect of several physical and chemical parameters, including solubility and particle size of the active ingredient and rheological properties of the dosage form. In most cases, in vitro release rate is a useful test to assess product sameness between prechange and postchange products. 14 Feb. 2011 Alliance Institute, Hyderabad

However, there may be instances where it is not suitable for this purpose. In such cases, other physical and chemical tests to be used as measures of sameness should be proposed and discussed with the Agency. With any test, the metrics and statistical approaches to documentation of “sameness” in quality attributes should be considered 14 Feb. 2011 Alliance Institute, Hyderabad

The evidence available at this time for the in vitro-in vivo correlation of release tests for semisolid dosage forms is not as convincing as that for in vitro dissolution as a surrogate for in vivo bioavailability of solid oral dosage forms. Therefore, the Center’s current position concerning in vitro release testing is as follows: 14 Feb. 2011 Alliance Institute, Hyderabad

In vitro release testing is a useful test to assess product “sameness” under certain scale-up and postapproval changes for semisolid products. 2. The development and validation of an in vitro release test are not required for approval of an NDA, ANDA or AADA nor is the in vitro release test required as a routine batch-to-batch quality control test. 14 Feb. 2011 Alliance Institute, Hyderabad

3. In vitro release testing, alone, is not a surrogate test for in vivo bioavailability or bioequivalence. 4. The in vitro release rate should not be used for comparing different formulations across manufacturers. 14 Feb. 2011 Alliance Institute, Hyderabad

Contract manufacturing

Definition of contract manufacturing
Production of goods by one firm, under the label or brand of another firm. Contract manufacturers provide such service to several (even competing) firms based on their own or the customers' designs, formulas, and/or specifications. Also called private label manufacturing. 14 Feb. 2011 Alliance Institute, Hyderabad

Contract manufacturing is a process that established a working agreement between two companies. As part of the agreement, one company will custom produce parts or other materials on behalf of their client. In most cases, the manufacturer will also handle the ordering and shipment processes for the client. As a result, the client does not have to maintain manufacturing facilities, purchase raw materials, or hire labour in order to produce the finished goods. 14 Feb. 2011 Alliance Institute, Hyderabad

Contract manufacturing.
The basic working model used by contract manufacturers translates well into many different industries. Since the process is essentially outsourcing production to a partner who will privately brand the end product, there are a number of different business ventures that can make use of a contract manufacturing arrangement. There are a number of examples of pharmaceutical contract manufacturing currently functioning today, as well as similar arrangements in food manufacturing, the creation of computer components and other forms of electronic contract manufacturing. 14 Feb. 2011 Alliance Institute, Hyderabad

Even industries like personal care and hygiene products, automotive parts, and medical supplies are often created under the terms of a contract manufacture agreement. In order to secure contract manufacturing jobs, the contract manufacturer usually initiates discussions with the potential client. The task is to convince the prospective customer that the manufacturer can use their facilities to produce quality goods that will meet or exceed the expectations of the customer. 14 Feb. 2011 Alliance Institute, Hyderabad

At the same time, the manufacturer will demonstrate how the overall unit cost of production to the customer will be less than any current production strategies in use, thus increasing the amount of profit that will be earned from each unit sold There are several advantages to a contract manufacturing arrangement. For the manufacturer, there is the guarantee of steady work. Having contracts in place that commit to certain levels of production for one, two and even five year periods makes it much easier to forecast the future financial stability of the company. 14 Feb. 2011 Alliance Institute, Hyderabad

For the client, there is no need to purchase or rent production facilities, buy equipment, purchase raw materials, or hire and train employees to produce the goods. There are also no headaches from dealing with employees who fail to report to work, equipment that breaks down, or any of the other minor details that any manufacturing company must face daily. 14 Feb. 2011 Alliance Institute, Hyderabad

All the client has to do is generate sales, forward orders to the manufacturer, and keep accurate records of all income and expenses associated with the business venture. The general concept of contract manufacturing is not limited to the production of goods. Services such as telecommunications, Internet access, and cellular services can also be supplied by a central vendor and private branded for other customers who wish to sell those services. Doing so allows the customer to establish a buy rate from the vendor, then resell the services at a profit to their own client base 14 Feb. 2011 Alliance Institute, Hyderabad

Scopes of contract manufacturing
The scope of the Contract Manufacturing Procurement business scenario outlined in this documentation only concerns the customer side (OED -The Office of Enterprise Development ). This business scenario does not cover how an ERP (Enterprise Relationship Management) system on the supplier's side (that is, the contract manufacturer's side) receives messages sent by the customer, and how it deals with the additional information (for example, components) submitted with these messages. 14 Feb. 2011 Alliance Institute, Hyderabad

Scopes of contract manufacturing
Mappings are only provided for A2A communication (between the OED's ERP system and SAP* SNC*) from IDoc to XML and vice versa. This business scenario does not cover the tracking of the manufacturing process (production phases) that takes place at the contract manufacturer's site - it does not take into account the current production phase at the contract manufacturer' site. Consequently, the OED planner cannot predict the supply situation of finished goods. * SAP- Supply Network Planning * SNC- Supply Network Collaboration 14 Feb. 2011 Alliance Institute, Hyderabad

Limits of contract manufacturing
The Contract Manufacturing Procurement business scenario has the following limitations: Once a schedule line in the ERP purchase order is changed, the date and quantity data originally requested are lost. Even if the information is stored in SAP SNC, it is not possible to send this information to the CM. The Contract Manufacturing Procurement business scenario is based on functions introduced in SAP ERP 6.0. For lower releases, you need to develop a customer modification. 14 Feb. 2011 Alliance Institute, Hyderabad

No data import control functions are provided for messages sent from the CM to SAP SNC. The bill of material (BOM) is not available in SAP SNC. New purchase order items cannot be created in SAP SNC. Product substitution is not supported. Scheduling agreements for the subcontracted material are not allowed. 14 Feb. 2011 Alliance Institute, Hyderabad

A supplier should be able to update the component consumption in SAP SNC until a good receipt has been posted in the customer ERP back-end system. The subcontracting scenario of the Rosetta Network Order Management Program as described in the PIPs* 7B5 (Notify of Manufacturing Work Order), 7B6 (Notify of Manufacturing Work Order Reply), and 7B1 (Work In Process Notification) is not included in the scope of SAP SCM*. * PIP- Partner Interface Process * SCM- Supply Chain Management 14 Feb. 2011 Alliance Institute, Hyderabad
