Your therapy is a force for good, and an experienced analytical services partner can help you ensure it meets regulatory standards and delivers the reliability that patients expect and require. With over a century of experience, Kindeva Drug Delivery has the expertise necessary to ensure compliance and quality of your drug, containment system, delivery system, device, or combination product. We perform our analytical and testing services in our Woodbury, MN, laboratory, in accordance with cGMP standards.  

Analytical method development & validation

Our analytical services support your product through clinical stage development with rapid response time and expert guidance. We ensure compliance with the most up-to-date USP guidance as well as the rigor of revised regulatory guidance such as ICH and ASTM. Utilizing scientifically justified decisions, methods are developed following a risk-based approach encompassing the life cycle of your product and intended use.  

With long-term support, alongside verification and transfer options, Kindeva is here to establish methods which are sustainable from batch release throughout your stability programs. 

Raw material testing

Our raw material testing services are adapted to your needs, helping you verify the safety and quality of your product. We execute most USP compendial testing and use a variety of analytical methods and tests, tailored to your unique concerns and considerations specific to your product.

Stability testing & storage

To ensure safety and meet regulatory requirements, you need to understand how your product can change, based on the environment in which it may be stored or transported. Our stability testing services characterize your product’s shelf life under diverse conditions. We have the following ICH storage conditions available: -20°C, 5°C, 25°C/60% RH, 25°C/75%RH, 30°C/65%RH, 30°C/75%RH, and 40°C/75%RH as well as temperature cycling. Other conditions are available upon request to meet the unique needs of your product.

At Kindeva, we specialize in providing comprehensive stability testing services, designed to ensure the efficacy, safety, and quality of your pharmaceutical and biotechnological products throughout their shelf life. Our state-of-the-art laboratories and experienced scientists are equipped to handle all aspects of stability studies:  

  • Real-time, accelerated, and intermediate stability studies following regulatory, ICH guidelines, and custom protocols that fit your unique product requirements 
  • Advanced environmental chambers: Our facility boasts a range of environmental chambers, calibrated for various temperature and humidity conditions, ensuring precise and reliable testing environments  
  • Continuous monitoring: Utilizing the latest technology, we provide continuous monitoring of your products, offering real-time data 
  • Robust analytical testing: Our laboratory employs validated analytical methods to accurately assess the stability characteristics of your products

Extractables & leachables testing

Compounds from your combination product’s container closure system, delivery system, containment system, and packaging that leach into your drug product can be a safety risk. Identifying and quantifying compounds that can be extracted from the drug product contact materials through aggressive means can inform the design of a leachables study. Leachables testing quantifies leachables that may be present in your drug product, migrating into the product over time under normal use and storage conditions. Kindeva uses a wide range of analytical equipment, including GC, GC/MS, headspace GC/MS, UPLC, and high-resolution accurate mass (HRAM) LC/MS/MS, to identify and quantify extractable and leachable compounds.
