GMP Development Process
One of the challenges of GMP nanoparticle production is defining the appropriate level of controls and processes to appropriately manage risk. For each customer, we collaboratively work through a multi-stage process to define a GMP transition plan that is appropriate for the target application. At the end of each stage we conduct a design review to evaluate the work completed and to plan the next stage.
An example of a typical development process is provided below:
Concept: Determining product’s feasibility & identify the scope of the project
Research & Development: Defining user needs and identify corresponding design inputs
Early GMP: Initiate Design Controls
Design Development: Identifying the stages, activities, responsibilities, resources, & verification methods for design & development
Product Development: Establishing a product design with detailed associated specifications
Verification & Validation
- Verification: Examining objective evidence to confirm specified requirements are met
- Validation: Obtaining objective evidence to assure that a product meets the intended user needs
Design Transfer: Transfer the process from development to commercial scale manufacturing; ensure all of the design requirements & product specifications can be met in commercial production, and identify potential problems before transfer to commercial GMP
GMP Manufacture of Photothermal Nanoparticles
Contract R&D · Scale-up for Production · GMP for ISO13485 Commercial Supply
Client: Sienna Biopharmaceuticals, a cilinical-stage biopharmaceutical company developing targeted topical products for medical dermatology and aesthetics
Sienna Biopharmaceutical partnered with nanoComposix to co-develop a photothermal acne treatment made of nanoparticles. The technology is made possible by highly concentrated silica coated silver nanoplates that are introduced into the hair follicles of over-productive oil glands. Standard dermatology lasers are then used to locally heat and impair the nearby sebaceous glands, reducing oil production and acne. In order to make this therapy successful, the silver nanoplates needed to be protected from the skin’s local environment. NanoComposix worked closely with Sienna to design and optimize the silica encapsulation, maximizing the formulation’s stability on skin and thereby increasing treatment efficacy.
Transfer to GMP manufacturing under QMS: NanoComposix developed a working prototype and helped Sienna define a formal Product Speciﬁcation, a critical early phase of GMP development. The transfer to GMP manufacturing for clinical supply and preparation for commercial production included:
- Repeatedly producing the material under all the necessary controls to ensure the material meet all criteria of the formal Product Specification
- Establishing a process flow diagram based on the R&D process and control points for In Process Quality Control (IPQC)
- Developing a Manufacturing Master Record (MMR), including Master Batch Records (MBR) and a Bill of Materials with qualified suppliers
- Process development to increase the standard batch size 100×
- Process Failure Mode and Eﬀects Analysis (pFMEA) to identify the risks in the material manufacturing
- Several iterations of robustness work to ensure a consistent manufacturing process at commercial scale
- Successful audits of nanoComposix to ensure QSR & ISO13485 requirements were met
NanoComposix is currently producing clinical supply material on-demand for this client and preparing for commercial production.
R&D of Nanoparticles as a Component of a Medical Device
Contract R&D · Product Development
Client: Diagnostic company
This client was developing a fluorescent-based lateral flow device for commercialization and was seeking a partner to produce ultra-bright nanoparticles that would help them achieve their sensitivity needs for their assay, as well as lateral flow assay development and manufacturing partner. After evaluating other nanoparticle and lateral flow development companies, they selected nanoComposix to develop a novel ultra-bright reporter particle for their assay and perform the assay development needed for pilot manufacturing. Over several months of collaboratively working with the client on particle and assay development, nanoComposix enabled them to meet their rigorous sensitivity targets for the project and provided all the necessary methods and SOPs for pilot scale manufacturing.
Process development included:
- Producing test reports and cataloguing in the design history file during the R&D stage
- Finalizing a product specification and conducing an FEMA
- Drafting manufacturing methods for each step and producing batch records for prototype runs
- Qualifying raw material suppliers and receiving materials under the QMS
- Holding design review meetings to review the specifications, manufacturing and test methods, and performing hazard analysis
- Performing engineering runs to deliver released batches to the customer
- At the end of the project, all manufacturing methods and the complete device history file was transferred to the customer
University Technology Transfer
R&D · Scale-Up · Establishing Pre-GMP Documentation
Client: Public university
For this technology transfer, the client contracted nanoComposix to assist in transferring their nanoparticle-enabled immune-stimulant technology from the university lab where it was developed to a commercial lab and to begin to establish manufacturing SOPs and to scale up synthesis production. nanoComposix worked closely with the client to ensure the procedures were comprehensively documented for successful transfer to outside laboratories while maintaining material quality and reproducibility. The nanoCompmosix team also investigated potential scale-up options, which would be required to reduce costs and produce the material at the target price-points for their end application.
Technology transfer steps included:
- nanoComposix scientists traveled to the university to observe and meticulously record every detail of the synthesis performed at the university
- Equipment and reagents were exactly duplicated for a successful repeat synthesis at nanoComposix
- nanoComposix conducted a preliminary sensitivity analysis to determine the variables that affected the critical parameters of the synthesis
- nanoComposix team drafted manufacturing methods at the small scale and documented additional details at critical steps
- Investigated scaling at 5×, 20×, and 100× using new fabrication and processing methods. The scaled solutions were measured using validated test methods
- Released batches were provided for safety and pre-clinical studies
Second Supplier for R&D Manufacturing
R&D · Product Development · Commercial Supply
Client: Private medical device company dedicated to dermatology therapies
This customer had been producing a proprietary topical therapeutic with a nanoparticle component and required a second supplier for their commercial technology. nanoComposix worked with them to replicate their established synthesis protocols, testing, and release procedures under our QMS so that we could be validated as a second supplier for their nanoparticle component.
GMP process development included:
- Client provided nanoComposix with their existing Manufacturing Master Record (MMR) and the synthesis was repeated in-house
- After developing a Quality Plan for the project, nanoComposix transferred and adapted the MMR documents into the nanoComposix QMS and performed engineering runs
- Additional test methods were developed and validated and new suppliers were qualified
- nanoComposix produced a cGMP compliant qualification batch and delivered the material to the client for evaluation
- At the successful completion of the project, the client approved nanoComposix as a verified second source
