Design for validation
Developing new technologies for medical applications requires extensive validation efforts. If not considered in the early design phase, validation becomes complex and not properly interlinked with practical operation. Chempilots applies “design for validation” on a daily basis:
- We resolve yield issues and validation deficiencies by redesigning existing process technologies.
- In order to obtain reliable solutions, we prioritize simplicity and safety in process design.
- New processes are challenged to identify robust operating windows and control objectives.
We can contribute to planning, executing and reporting of process validations through all steps (acceptance tests, IQ, OQ, PQ, PV).
Project example: Line automation
For Contura we studied and challenged a manual process technology for making injectable hydrogels. The immediate outcome was used to set production specifications and inline controls, and to support process validation.
Driven by new growth opportunities, the process technology now must be upgraded. Chempilots proposed a new automated line for production of the hydrogel, and prototype equipment was built. Processing studies were conducted in our lab demonstrating technical feasibility. A regulatory compliance pre-evaluation was also provided. Together with machine constructors, a full-size automated line was being fabricated and met validation requirements, in particular those of FDA 21 CFR part 820 (G).
Project example: Catheter assembling
Following a FDA inspection, a world-class supplier of catheters decided to have their manual assembly operations rescheduled to better meet validation requirements. We prepared scenarios of line automation/robotic sub-assembling versus change in sub-assembly stacking facilitated by redesigned key equipment.
As an outcome, we redesigned and prototyped new curing ovens for parts potting and bonding. In our lab we conducted oven pre-qualification and robustness bench tests. Our customer conducted production studies that showed better operating flexibility and better yields, and based on our bench tests the process was validated in a test site.
Other project examples
Many of our assigned projects are originated from process yield issues or validation deficiencies in our customer’s present GMP setup. Most of our customers are within the medical device or pharmaceutical industry, thus we are familiar with validation requirements. Combined with our extensive R&D expertise and experience it is very likely that we also can assist you in designing and pre-qualifying processes that can be appropriately and practically validated in your production site.
