Considerations for Biocompatibility Evaluation

by | May 20, 2021 | Biocompatibility, FDA, Gene and Cell Therapies, Medical Devices, Pharmaceuticals, Regulatory, Testing

Biocompatibility is one of the most critical performance studies that manufacturers need to perform as part of their product development process. ISO 10993-5 and ISO 10993-10 are FDA-recognized standards for biocompatibility. Whether you perform these studies in-house or send out samples to a third-party lab the protocol for biocompatibility assessment must be conducted in accordance with ISO 10993.

13 types of biological effects must be tested depending on the body contacting device:1

  • Cytotoxicity
  • Sensitization
  • Irritation
  • Material-Mediated Pyrogenicity
  • Subacute/Subchronic Toxicity
  • Genotoxicity
  • Implantation
  • Hemocompatibility
  • Chronic Toxicity
  • Carcinogenicity
  • Reproductive/Developmental Toxicity
  • Degradation

When deciding which type of biological effect needs to be tested the following factors must be considered:1

  • Nature of body contact of the product, which depends on the category of the product and the body contacting surface, such as
    • Surface devices that could have contact with intact skin, mucosal membrane, breached or compromised surface.
    • External communicating devices that could have contact with blood path, tissue, bone, dentin, or circulating blood and
    • Implantable devices that could have contact with tissue, bone, or blood.
  • Contact duration of the device with the surfaces mentioned above. The contact duration as per ISO 10993 is defined as limited duration which is ≤24 hours, prolonged duration which is >24 hours to 30 days, and devices that are permanently in contact with the body surface which is > 30 days.

Whether you are in the product development stage or conducting these tests for a pre-market submission, determining which tests to conduct can always seem confusing, but EMMA International is always there to assist you in all of your product development and regulatory needs.

FDA Adverse Event Reporting 

FDA Adverse Event Reporting 

When reporting an Adverse Event to the Food and Drug Administration (FDA) the best method is to utilize the FDA Adverse Event Reporting System (FAERS). FAERS is a database that contains adverse event reports, product quality complaints that led to an adverse event, and medication error reports1. All FAERS reports are easily accessible to the public. 
De Novo Classification

De Novo Classification

A device can be registered for the De Novo pathway if there is evidence of the safety and effectiveness of the device and there is not a previously legally marketed predicate device1. When determining if your device can go through the De Novo process there are two pathways available to determine the device classification.
Abbreviated 510k submission

Abbreviated 510k submission

There are three types of 510K, Premarket Notifications, which can be submitted to the Food and Drug Administration (FDA) traditional, abbreviated, and special. Abbreviated and Special 510K submissions can be utilized when the submissions meet the certain factors presented by the FDA. When submitting an abbreviated 510K the submission must include the elements that are identified in 21CFR 807.87 for the information required in a premarket notification submission.
