The Challenge
A pharmaceutical sponsor running a Phase 2B multi-center, randomized, double-blind trial faced a critical supply chain crisis. With frequent stockouts occurring and no documented plan for managing expiry dates, the sponsor risked treatment interruptions for their patients. While their product was on analytical stability to receive additional shelf life, and manufacturing was scheduled, the quantities wouldn’t meet immediate study demands due to delayed enrollment. This complex situation required immediate intervention to prevent study disruption and maintain patient treatment schedules.
Key Challenges:
- Multiple investigator sites and primary depots in the US and UK required expedited expiry date extensions
- No existing standard operating procedures (SOPs) for expiry date management at the sponsor or site level
- Blinded investigational products (IPs)—both active and placebo—complicated the process
- There was an urgent need for expedited production runs and resupply shipments
The Solution
Clinical Supply Consulting (CSC) stepped in with a comprehensive approach to address the sponsor’s immediate needs while implementing long-term solutions. Our team developed a strategic plan that combined regulatory-compliant labeling procedures with practical site-level implementation. We focused on minimizing disruption to ongoing trials while ensuring all sites had proper documentation and training to handle expiry date extensions effectively.
Key Solutions:
- Developed and implemented comprehensive SOPs and guidance documents for expiry date management
- Created regulatory-compliant expiry auxiliary labels for IP clinical extension labeling
- Provided specialized training to CRA/site monitors on the expiry date extension process
- Coordinated resupply shipments to sites and depots that were unable to perform extensions and/or required additional IP
The Results
Thanks to CSC, the study continued without pauses or interruptions, and no patients missed their scheduled treatments. All supplies were successfully extended or replaced before their original expiry dates, maintaining the integrity of the trial. The sponsor received approval to proceed with Phase 3, demonstrating the success of our supply chain management strategy. Most importantly, CSC’s proactive approach ensured zero treatment interruptions, showcasing our ability to handle complex supply chain challenges while maintaining patient care as the top priority.
