Why Legacy RTSM Systems Create Risk in Biosimilar Trials

Smarter Supply. Less Waste. Greater Control.

________________

Biosimilar development places sustained pressure on clinical supply teams to balance cost containment, product quality, and uninterrupted patient access. Comparator biologics are often scarce, expensive, and highly sensitive to handling and storage conditions. Every supply decision carries downstream implications for compliance, continuity of dosing, and inspection readiness.

From a clinical supply standpoint, success in biosimilar trials depends on having the right level of control, visibility, and flexibility across the entire supply chain. Elosity, Endpoint Clinical’s next‑generation RTSM platform, was designed with these realities in mind, helping sponsors strengthen supply resilience, reduce avoidable waste, and execute with confidence in even the most complex comparator‑dependent studies.

Why Legacy RTSM Systems Create Risk in Biosimilar Trials


Many RTSM platforms in use today were not built to manage the cost intensity, volatility, or compliance rigor associated with biosimilar programs. Over time, these limitations show up as operational inefficiency, unnecessary waste, and increased inspection exposure.

1. Limited Real-Time Operational Visibility

Legacy systems often provide delayed or incomplete insight into site‑level activity. Without real‑time visibility into inventory status, enrollment dynamics, or handling conditions, supply teams are forced to react after issues occur rather than intervene early

Without timely insight, teams often discover issues after deviations occur, increasing remediation effort and audit exposure.

Common challenges include:

  • Limited site-level inventory visibility
  • Delayed detection of temperatureexcursions or handling issues
  • Missed opportunities to correct issuesbefore they impact patients or compliance

2. Poor Integration with Forecasting Tools

Accurate forecasting is essential when managing high‑cost comparator biologics. Yet many RTSM platforms operate independently of forecasting tools, requiring manual reconciliation between planning assumptions and actual execution.

This disconnect often leads to:

  • Manual alignment between RTSM and forecasting systems
  • Inflated comparator orders due to static assumptions
  • Increased burden during regulatory review

3. Inflexible Supply Logic

Biosimilar studies rarely follow a straight line. Enrollment rates fluctuate, sourcing strategies evolve, and regional constraints shift over time. Rigid resupply rules in legacy systems struggle to accommodate this variability, increasing the risk of both stockouts and excess inventory.

Inflexibility typically shows up as:

  • Fixed resupply thresholds
  • Inflated comparator orders due to static assumptions
  • Increased burden during regulatory review

4. Limited Support for Complex Biosimilar Workflows

As sourcing models grow more complex, many RTSM systems fall short in supporting the workflows required for inspection‑ready execution. Gaps in traceability or process control can quickly translate into audit risk.

Examples include limited support for:

  • Local versus sponsor sourcing models
  • Central pharmacy strategie
  • Serialized medication requirements
  • Drug pooling and cross study allocation workflows
  • Complete, end-to-end audit trails

Our Solution: How Elosity Reduces Comparator Waste

Elosity, Endpoint Clinical’s next generation RTSM platform, was purpose‑built to address the operational and compliance challenges of biosimilar supply. From a clinical supply perspective, its value lies in aligning inventory decisions with real study activity, while maintaining the controls regulators expect.

1. Reducing Waste at the Site Level

Elosity continuously adapts supply to enrollment, visit schedules, and site performance. By responding to real‑world conditions rather than static forecasts, sponsors can right‑size inventory without compromising availability.

Key capabilities include:

  • End-to-end shipment tracking with real time chain of custody
  • Visit driven resupply aligned to actual participant activity
  • Site inventory monitoring with proactive alerts
  • Adaptive resupply based on live performance data

2. Depot-Side and Forecasting Integrations

Elosity integrates directly with leading forecasting platforms, enabling continuous replanning as study conditions change. This tight alignment reduces over‑ or under‑supply while improving documentation consistency across systems.

From an operational standpoint, this means:

  • Forecast assumptions are continuously reconciled against live enrollment, dispensing, and inventory data
  • Supply decisions adapt as conditions change, rather than relying on static planning snapshots
  • Forecast and RTSM records remain aligned, simplifying documentation and inspection readiness across the study lifecycle

3. Flexible Cross‑Study Pooling and Participant‑Level Supply Control

For sponsors managing multiple biosimilar programs, Elosity supports cross‑study pooling of comparator supply while maintaining full traceability. Participant‑level supply control allows teams to allocate inventory dynamically, protecting continuity of dosing during enrollment shifts or unexpected disruptions.

This flexibility helps:

  • Reduce emergency shipments and protocol deviations
  • Improve utilization of existing  comparator stock
  • Sustain uninterrupted study actively despite enrollment variability, sourcing changes, or unexpected opperational disruption

4.  AI Teammates for Faster Decision-Making

eloAI provides clinical supply teams with immediate access to operational and compliance‑relevant insights. By surfacing early risk indicators—such as slow‑moving inventory, temperature excursions, or emerging expiry risk—teams can act sooner and with greater confidence.

From a clinical supply standpoint, eloAI supports faster, more proactive decision‑making by helping teams:

  • Identify emerging inventory risk before it results in expiry, write-offs, or site-level constraints
  • Surface quality-impacting events, including temperature excursions or handling deviations, early enough to enable corrective action
  • Detect under-utilized or slow-moving supply that can be reallocated or transferred proactively
  • Reduce manual data review and reconciliation effort when assessing operational or compliance risk

Lessons Learned from Leading Biosimilar Sponsors

Across successful biosimilar programs, consistent themes emerge: strong visibility, disciplined inventory control, and the ability to adapt quickly. Elosity operationalizes these best practices by embedding them directly into RTSM workflows, enabling inspection‑ready execution at scale.

Common strategies supported by Elosity include:

  • Centralized pharmacy models for greater quality control and reduced waste.
  • Site-to-site transfers unlock smarter utilization of remaining inventory while maintaining traceability.
  • Drug pooling supports efficient use of comparator stock with fewer batch-level compliance constraints.
  • Continuous forecasting, informed by live RTSM data, consistently reduces waste and improves documentation accuracy.

What Sponsors can Expect

When these supply practices are consistently applied, sponsors experience changes that extend beyond reduced waste. From a clinical supply perspective, the impact is felt in day‑to‑day decision‑making, operational stability, and inspection readiness.

Sponsors commonly report:

1. Enhanced Real-Time Oversight

With centralized, real time‑ insight into enrollment, inventory, and site activity, sponsors can move from reactive issue management to proactive oversight. Early visibility into emerging risks enables faster intervention, reducing downstream deviations, waste, and operational strain.



What sponsors gain:

  • Clear visibility into enrollment, consumption, inventory patterns, and quality-impacting trends.
  • Early detection of waste drivers such as lagging enrollment, aging supply, improper storage, or compliance deviations.

2. Improved Inventory Control and Less Waste

By aligning supply more closely to real participant activity, Elosity helps sponsors right size‑ comparator inventory without compromising availability. Smarter planning and adaptive resupply reduce excess while maintaining continuity of dosing, even as enrollment patterns shift or operational conditions change.

Operational and cost benefits:

  • Targeted resupply and smarter planning reduce expiry events and minimize compliance exceptions.
  • Comparator demand more accuratley reflects real patient activity while ensuring quality standards are met.
  • Fewer emergency shipments, fewer deviations, and stronger record keeping.

3. Proven Impact Across Biosimilar Programs

Across biosimilar programs, these operational improvements translate into consistent, measurable performance gains. By reducing reliance on static assumptions and manual intervention, sponsors are better equipped to manage high cost comparator biologics with greater predictability, speed, and confidence throughout the study lifecycle.

Sponsors typically experience:

  • 10 to 30 percent reduction in total comparator waste, depending on sourcing and study design.
  • Accelerated decision cycles powered by AI insights.
  • Higher compliance confidence with stronger traceability, documentation integrity, and audit readiness.
  • More stable global supply with fewer overages, stockouts, and quality risks.
