Missteps in GMP Facilities and Equipment Maintenance

Pharmaceutical Technology, 26 December 2025

Key Takeaways

  • Multiple departments, including engineering and quality assurance, are responsible for evaluating GMP equipment and facilities.
  • Regulatory inspectors require well-organized, preferably digital, maintenance documentation during GMP audits.
  • A computerized maintenance management system (CMMS) is crucial for tracking maintenance activities and ensuring high performance.
  • Common mistakes include neglecting criticality assessments, relying solely on time-based maintenance, and failing to consider maintainability during design.
  • Adequate commissioning time is crucial for equipment lifespan and maintenance reliability.

Construction and maintenance of manufacturing buildings and equipment fall under good manufacturing practices (GMPs) regulations (1–5). Pharmaceutical manufacturers can comply with these rules in the form of risk-based maintenance programs. Pharmaceutical Technology® spoke with David Basile, VP Technical Operations, Americas, Hovione, about how companies can meet these requirements for GMP facilities and equipment and some of the common mistakes made when working toward compliance.

PharmTech: Which department is responsible for evaluating GMP equipment and facilities?
Basile (Hovione): The primary groups that participate in the evaluation of GMP equipment and facilities are engineering, maintenance, while quality assurance (QA) oversees compliance and approval. The best companies keep a few dedicated roles focused on maintenance planning and equipment reliability to drive best practices and implement the concepts of reliability centered maintenance.

Do regulatory inspectors request proof of maintenance? If yes, how should this be compiled and presented to the agency?
Yes, it's fairly standard for regulators to request proof of maintenance during GMP audits to verify compliance and confirm that we document all our activities related to the manufacturer and release of our products. You didn't do it, if you didn't document it. We compile detailed electronic records, including preventive maintenance schedules and calibration certificates. These should be presented in a clear and organized manner. In our recent inspections, we've seen that inspectors appreciate being able to get these records in a digital format for portability, and in case they'd like to reference them at their convenience.

Another element here is using what we call our computerized maintenance management system, or CMMS. This is a central repository for all of our maintenance-related activities. This is a key system in the efficient execution of any strong, compliant maintenance program. It provides detailed work order history, preventative maintenance instructions, asset specifications, scheduling, data and spare parts inventory, so we can see trends and pick up drift, for example, to clearly demonstrate that our assets remain in a state of high performance and quality operation. We'd really be flying blind without a CMMS. It's a tool that you can't live without in today's world of pharmaceutical maintenance.

What are the most common mistakes that manufacturers make when it comes to maintaining GMP equipment and facilities?
Failing to do a comprehensive criticality assessment and a risk-based approach, [which can result] in over or under maintenance [is one mistake]. Solely relying on time-based preventative maintenance versus proactive maintenance approaches such as precision alignment or lubrication [is another]. Today's teams need to incorporate conditions-based maintenance using technologies such as vibration analysis. They can no longer just fix things that break. They need to diagnose equipment, looking for early signs of failure before they fully develop. Other examples of this are ultrasound or infrared scanning to ensure motors and electrical systems are wired and operating properly.

Another mistake might be failing to consider design for maintainability during upgrades and not during the design phase. Adequate space and access to equipment, standardized tools, having the right pickups on equipment for condition-based maintenance [are important considerations]. I can't tell you how many times I've seen a filter housing or an instrument placed in the interstitial space above a ceiling with no way to safely access it. Failing to consider design for maintainability and not bringing maintenance in during the design phase is one mistake that people often make.

Not carving out a role for a dedicated maintenance planner is also a misstep. At Hovione, we have a dedicated reliability engineer and maintenance planner that help in the evaluation. This is critical to shorten the mean time to repair and ensure that all tools and supplies needed for the job are available and kitted to support fast first-time-right work order execution. These roles are game changers to the operation and take you from walking to sprinting, especially when candidates bring hands on experience. In fact, the best planners are usually seasoned mechanics.

One final failure we see often is not building in enough time for commissioning. The lifespan of equipment can be greatly influenced during the commissioning phase. This is where maintenance reliability starts. Too often, commissioning is rushed through, and equipment and preventive maintenance plans and required spare parts are not thoroughly assessed. In many cases, due to limited time, the CMMS system is not fully populated with key information to perform comprehensive root cause analysis.

The investment includes both continuous and batch tableting capabilities, as well as connect spray drying with tablet production at its East Windsor campus. Hovione, a Portugal-based contract development and manufacturing organization (CDMO), plans to install a continuous tableting line at its East Windsor, New Jersey campus, adding drug product manufacturing capacity and an integrated pathway from amorphous solid dispersion production through commercial tablet manufacturing. The $35 million investment will bring the first ConsiGma CDC Flex system to Hovione’s recently opened 89 Twin Rivers facility. The line is expected to be commissioned in late 2027 and will support both continuous and batch operation at throughputs ranging from 1 to 200 kilograms per hour, according to the announcement. The system will allow customers to use the same equipment for development, clinical, and commercial production, with formulation development possible using as little as 1.5 kilograms of material. Hovione said the line will also be equipped for containment to 1 microgram per cubic meter to support the handling of highly potent compounds. The new capability will also connect Hovione’s spray-drying operations with tablet manufacturing at the East Windsor campus. The company recently opened a 31,000-square-foot facility at the campus with two commercial-scale spray dryers for manufacturing amorphous solid dispersions (ASDs), completing a $100 million investment in its New Jersey operations. Hovione said the integrated setup will allow customers to move from formulation and particle engineering through tablet production under one quality system, reducing technology transfer requirements and eliminating traditional scale-up between development and commercial production. The ConsiGma CDC Flex platform was jointly developed with GEA as part of a collaboration that began in 2022, the company said. The system incorporates automated process controls and process analytical technology for real-time monitoring during production. Hovione already operates continuous tableting technology at its Loures, Portugal site. In August, the company completed a more than €40 million expansion of its tablet development and manufacturing center there, adding a second commercial-scale tableting line and increasing the center's manufacturing area by 25%. The East Windsor installation will extend Hovione’s continuous tableting capabilities to the U.S. and expand its integrated drug development and manufacturing services for oral solid dosage products.

Hovione to add $35M continuous tableting line at New Jersey site

Oct 06, 2026

Hovione, a globally integrated pharmaceutical contract development and manufacturing organisation (CDMO), will commission the world’s first ConsiGma CDC flex – a next generation continuous tableting line – at its East Windsor, New Jersey (USA) campus in late 2027. The line will be installed at 89 Twin Rivers, Hovione’s recently opened facility, expanding the company’s drug product capabilities and strengthening its integrated pharmaceutical development and manufacturing hub in the US. CDC ConsiGma flex system The project represents an investment of $35 million. Once installed it will create an integrated pathway from amorphous solid dispersion manufacturing via spray drying through commercial tablet production. The new flex will operate in continuous or batch modes across a very broad throughput range (from one to 200 kg/h). Customers will be able to develop a formulation using small quantities of material, down to 1.5 kg, and then run from very small clinical batches to large commercial batches using the same equipment. This is enabled by specialised design within the flex to effectively switch between continuous blenders of various sizes. Additionally, the line will be installed for containment to 1 µg/m³, supporting highly potent compounds. Continuous tableting is reshaping manufacturing of oral solid dosage medicines and is well suited to programmes in which speed, supply resilience and efficient use of high-value active pharmaceutical ingredients (APIs) are priorities. Inline process analytical technology (PAT) and automated controls also provide real-time quality monitoring. In parallel, the 2022 adoption of ICH Q13 regulatory framework, guidance specifically for continuous manufacturing of drug substances and drug products, provides harmonisation across the US, Europe and Japan. As of 2024, 17 products manufactured under the international guidance have been approved by the US Food and Drug Administration (FDA) alone.  Developed jointly with GEA, the ConsiGma CDC flex platform also incorporates SimpleCT, a suite of automation and control tools with smart interfaces that supports a single process from development to commercial supply. Designed for versatility and ease of use, these innovative developments simplify operation, improve efficiency and containment, and enhance operator safety. Read the full article at Pharma Press UK

Hovione to commission world’s first ConsiGma CDC flex, bringing next-generation continuous tableting to the US

Oct 06, 2026

Key Takeaways Commissioning a US-based ConsiGma CDC Flex line enables end-to-end spray drying-to-tablet manufacture within a single site and quality system, reducing comparability and technology-transfer burdens. Elimination of conventional scale-up is enabled by using the same equipment from early development through commercial supply, minimizing engineering runs and conserving scarce API. Operational flexibility spans batch or continuous modes and 1–200 kg/h throughput, with scale adjustment achieved by switching continuous blenders rather than replatforming processes. High-containment design to 1 µg/m³ expands suitability for highly potent oral solid-dose programs while maintaining integrated development-to-commercial workflows. Regulatory momentum for continuous manufacturing is supported by ICH Q13 harmonization, increasing FDA approvals, and platforms leveraging inline PAT and automated control suites for real-time quality assurance. Hovione announced on Oct. 5, 2026, that it will commission the ConsiGma CDC Flex, a next-generation continuous direct compression tableting platform jointly developed with GEA. The investment is designed to link amorphous solid dispersion manufacturing via spray drying with commercial tablet production at a single US site operating under one quality system. The line will run in either continuous or batch mode at throughputs from 1 to 200 kg/h. Formulation development can begin with as little as 1.5 kg of material, and the same equipment can then support everything from very small clinical batches to large commercial runs, enabled by a design that allows the system to switch between continuous blenders of different sizes. The installation will also be contained to 1 µg/m³ to accommodate highly potent compounds. "Hovione will be the first company in the world to offer the ConsiGma® CDC Flex, bringing this next-generation technology with unprecedented flexibility, simplicity and cost-efficiency in continuous tableting," said Marco Gil and António Almeida, co-CEOs, Hovione, said in a press release. "This investment also advances our strategy of building integrated capabilities close to customers in key markets. By adding this new line at East Windsor, we are broadening access to this technology in the U.S. and giving customers a more direct and accelerated path for developing and commercializing complex oral medicines." What Does a Single Development-To-Commercial Line Change? For formulators and process engineers, the most consequential claim is the removal of traditional scale-up. Moving a process from development equipment to commercial equipment typically requires engineering runs, bridging work, and consumption of scarce API, all of which weigh heavily on early programs with limited material. "Installing the CDC Flex at 89 Twin Rivers makes continuous tableting part of an integrated US development and manufacturing workflow," said David Basile, Vice President of Technical Operations, Hovione, in the press release. "Customers can move from formulation and particle engineering to commercial tablets with one Hovione team and one quality system, eliminating traditional scale-up while gaining greater production flexibility, process control and supply continuity." Co-locating spray drying and tableting is also significant because amorphous solid dispersions remain a primary solubility-enhancement route for poorly soluble molecules, and transferring intermediates between sites or vendors adds technology transfer and comparability burdens. The new line builds on the company's earlier US expansion; Hovione recently completed a $100 million investment to bolster US capacity in particle design, amorphous solid dispersions via spray drying, and batch and continuous tableting. How Is the Regulatory Environment Shaping Continuous Tableting Adoption? The company points to the 2022 adoption of ICH Q13, which provides harmonized guidance for continuous manufacturing of drug substances and drug products across the US, Europe, and Japan. Hovione reports that, as of 2024, FDA alone had approved 17 products manufactured under the guidance. Speaking on ICH Q13, FDA's Kelley Burridge, PhD, "Perceived barriers to continuous manufacturing have been falling one by one," and noted an FDA publication showing faster approval times for products with continuous manufacturing elements than for comparable batch products. The platform incorporates inline process analytical technology and automated controls for real-time quality monitoring, along with SimpleCT, an automation and control suite intended to support a single process from development through commercial supply. For sponsors weighing supply resilience and regional sourcing, the East Windsor installation extends a capability that Hovione says only it currently offers as a contract development and manufacturing organization.   Read the full article at PharmTech.com
