Why primary packaging matters
Why primary packaging matters
Primary packaging represents far more than a simple container system - it functions as an integral component of the drug product that can directly influence stability, efficacy, usability, and patient safety throughout the product lifecycle. The complex interactions between formulation components and packaging materials including vials, syringes, stoppers, and closure systems can significantly affect product performance during storage, transportation, and administration phases. For sterile injectable products, selecting and validating appropriate primary packaging early in development is essential to ensure chemical compatibility and minimize extractables/leachables risks, maintain functional integrity across diverse storage and transport conditions, ensure compatibility with fill-finish processes and delivery devices, and meet regulatory requirements for container-closure system qualification. Packaging-related issues, when identified late in development, can cause significant delays in clinical trials, require expensive formulation modifications, substantially increase overall development costs, and potentially compromise product quality or patient safety.

Who it`s ideal for?
This service is especially valuable for teams developing sterile injectable products requiring optimal primary packaging selection and comprehensive compatibility evaluation to ensure product quality and regulatory compliance throughout development and commercialization.
It applies across vials, prefilled syringes, cartridges, and specialized delivery systems for liquid, frozen, and lyophilized presentations, with expertise in complex biologics, high-concentration formulations, and specialized administration requirements.
Whether you're selecting container-closure systems early in development, evaluating device compatibility for patient administration, preparing regulatory submissions, or troubleshooting packaging-related issues, our assessment ensures optimal product protection and performance.






Why partner with Leukocare?
Leukocare integrates primary packaging compatibility testing seamlessly into preformulation, formulation development, and process development workflows with systematic studies that assess the impact of container-closure systems on stability, usability, and handling characteristics beginning in early development phases when changes are still feasible and cost-effective.
We evaluate packaging configurations relevant to diverse product presentations including vials, prefilled syringes, and cartridge systems for liquid, frozen, and lyophilized formulations. Our testing capabilities extend to specialized clinical in-use studies that simulate real-world handling and administration scenarios with appropriate analytical support.
Our team brings extensive experience with regulatory requirements for container-closure qualification and understands the complex relationships between packaging materials, formulation components, and product performance, enabling us to provide practical recommendations that balance product protection with manufacturing feasibility and regulatory compliance.
We provide actionable outputs, not just
observations. Our team integrates
structural biology, data science
and formulation development to deliver a single coherent story—risk scores, liabilities and
hypotheses that directly inform design of
experiments and decision points. Beyond
assessment, we offer connected services
so your program can move seamlessly into
optimization, extended stability packages
and small-scale non-GMP manufacturing
without losing momentum.

Identification of relevant analytical methods for adeno-associated virus stability assessment during formulation development
Formulation of adeno-associated viral (AAV) vectors requires analytical methods that are predictive of stability, use minimal material, and allow high-throughput testing—criteria that are often difficult to meet. This exploratory study assessed several analytical techniques for their ability to predict or indicate AAV stability. Two methods emerged as particularly promising: extrinsic differential scanning fluorimetry with SYBR Gold for genome release detection, and nano differential scanning fluorimetry for capsid stability. Size-exclusion chromatography with multi-angle light scattering and UV was also effective for monitoring particle size and genome load.
