    Case Studies

    Examples of implemented improvements for Contracted projects

    Addressing our clients’ challenges and pursuing better manufacturing methods

    Contract manufacturing gives rise to a wide range of challenges, such as “The manufacturing conditions have not been established,” “It works in the lab, but scaling up is difficult,” and “We want to further improve yield and quality.”

    To address these challenges, we verify manufacturing conditions and processes one by one and consider improvements from the standpoints of both quality and productivity.

    Drawing on the experience and technologies we have cultivated through our manufacturing operations, we share challenges with our clients and work toward more stable manufacturing methods and higher productivity. We believe that this is our role in contract manufacturing.

    Here we introduce examples of improvements that we have actually worked on together with our clients.

    Example 1

    Enabling commercial-scale production in a short period based on laboratory data, in response to a sudden increase in end-user demand.

    Challenge

    Company A (a chemical materials manufacturer) had synthesized samples on a scale of several tens of grams, which were being evaluated by the end user, when adoption was suddenly decided. Evaluation of product manufactured using actual production facilities was urgently required, making it necessary to quickly produce batches of several tens of kilograms. In addition, production on a commercial scale in batches of several hundred kilograms had to be anticipated within six months.

    Solution and results

    After receiving the project, we conducted small-scale experiments and, following about one month of study, carried out small-scale production using actual production facilities. Through multiple small lots and repeated improvements and refinements, we established the manufacturing method. As a result, we manufactured 100 kg of the product according to the schedule requested by the client, with no issues in either yield or quality.

    Laboratory glassware lined up
    Example 2

    We identified the causes of impurity formation and proposed reaction conditions and handling conditions for each step. We also optimized the process and established reaction conditions suitable for industrial production.

    Challenge

    Company B (a pharmaceutical company) requested the manufacture of a new API candidate prior to clinical trials. With the synthesis method disclosed to us, many impurities formed in each reaction, and the handling of intermediates and the purification yield were not stable. In addition, the manufacturing process was based on laboratory study and had not been designed with future industrial-scale production in mind, making it difficult to manufacture production using actual production facilities.

    Solution and results

    By identifying the causes of impurity formation in each reaction, optimizing reaction conditions and catalyst amounts to suppress impurities, and establishing appropriate storage conditions, we stabilized product quality and achieved excellent product quality. At the same time, we reviewed the operations of each process step, achieving significant cost reductions. Furthermore, by addressing scale-up challenges through laboratory studies, we established reaction conditions and process operations suitable for production using actual production facilities, thereby developing a reliable manufacturing process.

    Laboratory glassware and analysis
    Example 3

    We proposed changing the catalyst used in a coupling reaction. Stable reactions and suppression of impurities improved yield and significantly reduced costs.

    Challenge

    In the manufacturing flow developed by Company C (a chemical materials manufacturer), heat generation during the reaction was difficult to control, and sudden exotherms posed a safety problem. In addition, large amounts of insoluble impurities formed during the reaction, requiring a filtration step after the reaction to remove them, which was a challenge for scale-up.

    Solution and results

    Changing the reaction catalyst made stable reaction control possible and dramatically improved safety. By-product impurities were also suppressed, and the simplified filtration step enabled a substantial increase in lot scale, greatly contributing to cost reduction.

    Results in figures

    • Insoluble matter15w%→0%
    • Yield50%→70%
    • Maximum lot size90kg/lot→300kg/lot

    Quality Assurance

    Quality assurance

    The critical mission that we must fulfill is to reliably provide client-trusted products through the manufacture and contract manufacturing of active pharmaceutical ingredients, intermediates, and investigational drugs; advanced chemicals; functional cosmetic ingredients; and other products. In order to ensure the quality of our manufactured products, we have established a quality-assurance system based on cGMP concepts and appropriately manage all steps in the process, from the acceptance of raw materials to manufacturing, quality testing, storage, and delivery. We also work to achieve continuous improvements by having each and every employee feel a sense of responsibility for the quality of what we provide.

    GMP Process

    cGMP-based quality-assurance system

    Based on cGMP concepts, the Manufacturing Department and Quality Department have clarified their respective responsibilities and roles and work to ensure product quality while collaborating with one another. We carry out a wide range of quality-assurance activities encompassing not just the appropriate management of everything from the acceptance of ingredients to product testing and delivery approval but also measures designed to ensure data integrity.

    Data Integrity

    Initiative for Data integrity

    Inspecting equipment while checking records

    Reliable data as the foundation underpinning the assurance of quality

    We regard data integrity (DI) as a critical element of quality assurance. Data generated and recorded in manufacturing, testing, quality assurance, and other operations constitute information that is important for guaranteeing product quality. For this reason, we stress the importance of ensuring the authenticity, legibility, and integrity of data; we have developed the required equipment and procedures; and we have been working to put in place an environment to allow data to be appropriately generated, recorded, and saved. We have also been striving to cultivate a corporate culture to deepen understanding of data integrity and ensure the appropriate handling of data through the provision of education and training to employees. Making a commitment to data integrity a core pillar of our quality-assurance activities facilitates the provision of highly reliable products.

    Continuous Improvement

    Initiative for continuous quality assurance

    Reviewing records to consider corrective and preventive actions

    Rather than feel that our job is done once a quality-assurance system is put in place, we believe that it is vital to have such a system be continuously reviewed and improved. We engage in the following quality-assurance activities by using information obtained from our day-to-day manufacturing and quality-control activities.

    1. Monitoring the operational performance of processes and product quality
    2. Implementing a corrective and preventive action (CAPA) system
    3. Implementing a change-control system
    4. Conducting management reviews of the operational performance of manufacturing processes and product quality

    Through these activities, we appropriately ascertain and manage quality-related risks and endeavor to continuously improve our quality-assurance system.

    Customer Trust

    Quality assurance that measures up to the trust placed in us by our clients

    Business partners shaking hands firmly

    The products we handle, including active pharmaceutical ingredients, intermediates, and investigational drugs; advanced chemicals; and functional cosmetic ingredients, need to be maintained in a high-quality state and supplied on a consistent basis. When it comes to contract manufacturing in particular, it is important that we accurately understand the client’s requirements and link them to product quality. We regard quality as an important basis of corporate activities and are striving to develop a manufacturing environment in which our clients can confidently place their trust through our cGMP-based quality-assurance system, an appropriate approach to data management, instruction and training, and ongoing improvements. We will continue to pursue quality assurance that lives up to the trust of our clients and aim to become a company selected by clients as a long-term partner.

    Hands reviewing documents and a tablet during a meeting

    Made up of Sogo Pharmaceutical Co., Ltd., SOGO Trading Co., Ltd., and SPC (Shanghai) Co., Ltd., the Sogo Pharmaceutical Group regards compliance as complying with laws and regulations as well as acting in accordance with higher ethical standards as required by society as reflected in social norms and morality. In the constantly changing business segments corresponding to pharmaceuticals and chemicals, having foresight, being willing to take on the challenge of developing new products, and speed are valued highly. We believe, however, that taking on this challenge must be done at all times in a manner that is consistent with social ethics, in other words, compliance. Since avoiding incidents and disasters is deemed to be the starting point for ensuring our corporate continuity, we are committed to safe operations and the prevention of disasters. The Sogo Pharmaceutical Group sees taking on challenges, safe operations, and compliance as the cornerstones of our corporate activities. Accordingly, we engage in management with an emphasis placed on compliance. Proper awareness and actions on the part of each and every person working for the Sogo Pharmaceutical Group are important for realizing compliance. We feel that asking yourself each time whether an action—even if it technically comes within the bounds of the law—is correct and right is essential for conducting business in a fair manner. The Sogo Pharmaceutical Group aims to grow alongside society by earning the trust and meeting the expectations of clients, shareholders, business partners, employees, local communities, and all other stakeholders and by providing innovative products and services through actions undertaken by each and every officer and employee according to high ethical standards and an elevated sense of responsibility in the course of the performance of day-to-day duties.
