Summary
- ADCs are among the most demanding oncology therapies to transport
- Examples include PADCEV®, TIVDAK®, ADCETRIS®, and Sigvotatug vedotin
- ADCs typically require validated temperature-controlled transport conditions
- Airport dwell, customs delays, and operational disruption are major excursion risks
- Runtime and visibility are increasingly important in ADC logistics
- SkyCell combines long-runtime hybrid containers with operational visibility and Validaide intelligence to support global ADC supply chains
What Are Antibody-Drug Conjugates?
Antibody-drug conjugates, commonly known as ADCs, are targeted cancer therapies that combine:
- A monoclonal antibody
- A cytotoxic drug payload
- A specialized linker connecting the two
The antibody helps deliver treatment directly to cancer cells while minimizing damage to healthy tissue.
ADCs have become one of the fastest-growing areas in oncology because they combine the targeting capabilities of biologics with the potency of traditional chemotherapy.
Examples include:
- PADCEV® (enfortumab vedotin)
- TIVDAK® (tisotumab vedotin)
- ADCETRIS® (brentuximab vedotin)
- Sigvotatug vedotin
These therapies are increasingly used across a range of solid tumors and hematologic cancers.
Why ADC Logistics Are Particularly Challenging
ADCs present several unique logistics challenges.
High Product Value
Many ADC therapies represent years of research and development investment.
Individual shipments can contain extremely high-value inventory, making excursion prevention and shipment integrity critical.
Complex Biological Structures
Because ADCs incorporate monoclonal antibodies, they are sensitive to environmental conditions throughout storage and transport.
Maintaining validated temperature ranges helps ensure product quality and therapeutic performance.
Global Distribution Networks
ADCs are increasingly shipped through international supply chains involving:
- Manufacturing sites
- Clinical trial locations
- Distribution hubs
- Hospitals
- Specialty treatment centers
These networks often involve multiple logistics providers and transportation modes.
Patient Impact
Unlike many commercial products, delays or product loss can directly affect patient treatment schedules.
This increases the importance of reliable cold chain logistics.
What Temperature Conditions Are Typically Required For ADCs?
Specific storage and transport requirements vary by product and regulatory approval.
Many ADCs are transported within refrigerated conditions, commonly between:
However, pharmaceutical companies must always follow the approved storage conditions for each individual therapy.
The challenge is not simply maintaining temperature during normal transport.
The greater challenge is maintaining those conditions during:
- Airport dwell
- Customs inspections
- Flight delays
- Handovers between logistics partners
- Infrastructure interruptions
These are often the moments when excursions occur.
What Packaging Is Used To Transport ADCs?
Pharmaceutical companies use a range of temperature-controlled packaging solutions depending on shipment volume, lane complexity, and product requirements.
Thermal Shippers
Thermal shippers are commonly used for:
- Clinical trial materials
- Smaller-volume commercial shipments
- Regional distribution
Examples include solutions from:
- va-Q-tec
- Sonoco ThermoSafe
- Cryopak
These systems use advanced insulation and thermal materials to maintain temperature during transport and can perform well on predictable lanes with defined transit windows.
Active Containers
Active containers use powered refrigeration systems to maintain temperature throughout transport.
Examples include:
- Envirotainer RAP/e2
- CSafe RKN
Advantages include:
- Continuous powered temperature control
- Established use across pharmaceutical airfreight networks
Operational considerations include:
- Dependence on charging infrastructure
- Additional coordination requirements during delays and handovers
Hybrid Containers
Hybrid containers maintain validated temperature ranges without requiring external power during transit.
Examples include:
- SkyCell 1500X
- SkyCell 6500X
Advantages include:
- Long autonomous runtime
- Reduced infrastructure dependency
- Strong resilience during operational disruption
Hybrid systems are increasingly used for high-value biologics and oncology medicines moving through complex international supply chains.
Why Runtime Matters For ADC Shipments
Runtime is one of the most important factors in ADC logistics.
A shipment may be scheduled for only a few days of transport, but real-world pharmaceutical logistics rarely follows ideal conditions.
Unexpected events may include:
- Airport congestion
- Customs delays
- Weather disruption
- Missed connections
- Ground handling delays
When delays occur, packaging systems with longer runtime can continue protecting products without immediate intervention.
This additional protection window helps reduce excursion risk and supports supply chain resilience.
Why Airport Operations Are A Major Risk Point
Many pharmaceutical temperature excursions occur during airport operations rather than during flight.
Potential risks include:
- Tarmac exposure
- Delayed transfers
- Warehouse congestion
- Customs inspections
- Misplaced shipments
For ADCs, these operational disruptions can be particularly significant because of the high value and complexity of the products being transported.
This is why pharmaceutical companies increasingly evaluate cold chain systems based on their ability to tolerate disruption rather than only their laboratory performance.
Visibility And Monitoring In ADC Logistics
Modern ADC supply chains increasingly depend on visibility.
Companies are looking for:
- Real-time temperature monitoring
- Location tracking
- Delay detection
- Predictive risk analysis
- Intervention capability
Visibility allows logistics teams to identify risks early and take corrective action before product integrity is compromised.
How SkyCell Supports ADC Logistics
For high-value biologics and oncology medicines, SkyCell combines long-runtime hybrid containers with operational visibility and lane intelligence.
The SkyCell 1500X provides more than 270 hours of runtime, while the 6500X provides more than 300 hours without requiring external power during transit.
Combined with airport visibility infrastructure and predictive operational insights through Validaide, this approach helps pharmaceutical companies manage risk across complex international oncology supply chains.
SkyCell reports a temperature excursion rate below 0.05% across global operations.
Why ADC Logistics Will Continue To Grow In Importance
The global ADC market continues to expand rapidly.
As more therapies move through clinical development and commercial distribution, pharmaceutical companies face increasing pressure to:
- Protect product integrity
- Reduce excursion risk
- Improve supply chain resilience
- Support global patient access
This means cold chain logistics is becoming a strategic component of oncology commercialization rather than simply a transportation function.
What This Means For Pharmaceutical Companies
As ADCs become more widely used, pharmaceutical companies increasingly need logistics systems capable of protecting highly sensitive therapies across complex global supply chains.
The strongest solutions increasingly combine:
- Temperature stability
- Long runtime
- Operational resilience
- Visibility
- Excursion prevention
- Coordinated intervention capability
to ensure therapies arrive safely and effectively.
