Similarly, the EMA has integrated LER considerations into its regulatory framework. In its revised "Questions and Answers for Biological Medicinal Products" (February 2025), the EMA explicitly recognized PDA TR 82 as a relevant standard for designing LER studies. pda technical report 82 pdf
In this post, we will unpack the critical insights from the TR-82 PDF, moving beyond the generalities of "hold at low pH" to the specific science of how to validate it when your molecule is fighting you every step of the way.
In alignment with ICH Q9, TR 82 champions a risk-based approach. Manufacturers should utilize tools like Failure Modes and Effects Analysis (FMEA) to identify vulnerabilities in the cold chain. Common risks include: Liquid nitrogen depletion in dry shippers. Power outages affecting ULT freezers. This public link is valid for 7 days
PDA Technical Report No. 82 (TR 82), titled , provides a comprehensive framework for identifying, studying, and mitigating the masking of endotoxins in biologic drug products.

According to PDA TR 82, LER is defined as the inability to recover at least 50% of the spiked endotoxin activity over time. A key criterion is when two consecutive time points fail to achieve ≥ 50% recovery. 3. Mitigation Strategies
Based on the findings of this review, we recommend that:
The PDA TR 82 provides a detailed framework for the evaluation and control of extractables and leachables in pharmaceutical products. The report covers the following key areas:
