YOUR SCIENCE. YOUR STAGE. YOUR PATHWAY.

What does your next phase actually need?

Not every program needs a commercial-scale solution. Find the right starting point for yours.

Phase 1 GMP Decision Matrix01 / YOUR PROGRAM

An informed starting point—not a substitute for a program-specific CMC assessment.

YOUR PHASE-APPROPRIATE OVERVIEW

Connect your process to your IND.

Process development & regulatory planning

  • Assess comparability of toxicology and clinical material
  • Plan specifications, stability and analytical qualification
  • Align your manufacturing strategy with your IND package

Assess expression, purification, potency and single-use process compatibility. Evaluate 50–200 l as a planning range, subject to yield, dose and process fit.

Avoid scaling too early

Locking in commercial-scale capacity before clinical demand is defined.

A BRIDGE. NOT A BOTTLENECK.

Move your science forward.
Not your commercialization timeline.

Keep early development agile. Build the bridge to commercial scale when the science is ready.

BUILD THE FOUNDATION

Process development, characterization and a regulatory strategy grounded in your science.

ONE PLATFORM. TWO CONNECTED DISCIPLINES.

Manufacturing meets
regulatory intelligence.

As a division of Innovative Regulatory Science Group, Bench To Batch connects your manufacturing pathway with your regulatory strategy. Process, quality and CMC documentation move in the same direction—from day one.
