Anti-Drug Antibody Assay Validation, An Industry Perspective

Abstract: Biotherapeutic compounds have a potential to induce unwanted immune response resulting in variable clinical impact – from no effect to potentially life threatening events. Reporting of unwanted immunogenicity is one of the key elements in the regulatory submissions for product approvals. Immunogenicity is typically assessed by detecting anti-drug antibody (ADA) responses in drug specific ADA assays. In this presentation we will discuss relevant regulatory FDA guideline document and industry challenges.

Friends and Colleagues,

The government has classified the biopharma industry as essential during this trying time. As such, CuriRx is keeping our doors open for business.

We will continue to provide quality contract R&D services in a timely manner and do our part to contribute patient care. At CuriRx, the health and well-being of our employees, clients, and the general public are still our topmost concern and priority. Internally, we are encouraging all staff to adhere to calls for social distancing, asking that they work remotely when possible and maintain a measure of physical distance while working in the lab.

As this pandemic continues to challenge our communities, we have also implemented a number of additional safety measures around the office, including extra hand sanitizer dispensers, “deep cleaning” of all surfaces and doorknobs with heavy duty disinfectants, and encouraging video conferences even internally to discourage the gathering of too many people in one room at a time.

As always, we will continue to monitor the situation globally and adjust our behavior according to federal, state and public health guidelines.

Stay safe and healthy,

CuriRx, Inc.
