Root Cause Determination for Customer Complaint Biopharmaceutical Drug Product Samples with Abnormal Appearance

Area of Science:

• Pharmaceutical Science
• Quality Control
• Analytical Chemistry

Background:

• Customer complaints regarding drug product abnormalities can occur despite stringent quality control.
• Investigating these complaints is crucial for manufacturers to maintain product quality and safety.

Purpose of the Study:

• To investigate three distinct customer complaints involving Amgen drug products with visible abnormalities.
• To determine the root cause of product abnormalities and implement corrective actions.

Main Methods:

• Conducted comprehensive root cause analyses (RCAs) for each complaint.
• Utilized orthogonal analytical test methodologies to identify contaminants.
• Evaluated potential contamination sources, focusing on manufacturing versus healthcare provider facilities.

Main Results:

• RCAs excluded manufacturing processes as the source of contamination.
• Identified non-Amgen products (Vitamin B12, fosaprepitant, iron/saline) as contaminants in the affected vials.
• Concluded that mishandling at healthcare provider facilities was the likely cause.

Conclusions:

• Root cause determination is essential for effectively addressing customer complaints.
• Identifying external contamination sources ensures biopharmaceutical product quality, safety, and efficacy.
• Effective complaint handling involves communication with relevant parties.
