CMC Strategy for Late-Stage Development: Process Characterization, Validation, and Regulatory Readiness
Ensuring a Robust and Scalable CMC Strategy for Phase 2, Phase 3, and Commercialization
As a drug candidate progresses beyond early clinical development (Phase 1) into Phase 2, Phase 3, and commercialization, the CMC strategy must evolve to meet increasingly stringent regulatory, technical, and quality requirements.
At 3Biotech, we provide comprehensive CMC support for late-stage development, focusing on:
Process Characterization & Validation for drug substance and drug product
Analytical Method Validation & Lifecycle Management
Regulatory Submission Readiness (BLA, MAA, NDA)
GMP Commercial Manufacturing Readiness
Our expertise covers both small molecules and biologics, ensuring seamless scale-up, process robustness, and regulatory compliance.
Process Characterization
A well-characterized and validated manufacturing process is essential for regulatory approval and commercial readiness. Our science-driven approach ensures process robustness, reproducibility, and compliance with ICH Q11, FDA, and EMA guidelines.
We conduct a detailed assessment of critical process parameters (CPPs) and their impact on critical quality attributes (CQAs) using Quality by Design (QbD) and Design of Experiments (DoE) principles.

What is process validation (Process Performance Qualification, PPQ) in pharmaceutical manufacturing?
Process Performance Qualification (PPQ) in pharmaceutical manufacturing is a critical stage of process validation. It ensures that a manufacturing process consistently produces high-quality products that meet regulatory standards under normal operating conditions.
PPQ also evaluates the long-term robustness and reliability of the process, going beyond initial validation.
How do you characterize a biologics manufacturing process?
Characterizing a biologics manufacturing process involves a systematic approach to understanding, controlling, and improving all stages of production, from cell line development to final product purification and formulation.
This process identifies key parameters to ensure consistency, safety, and regulatory compliance, ultimately ensuring the consistent quality and reproducibility of the final product.
What is continued process verification (CPV) and why is it required?
Continued Process Verification (CPV) is the ongoing monitoring of a manufacturing process to ensure it consistently produces products with the desired quality attributes throughout the product lifecycle.
CPV is required for regulatory compliance and helps maintain product quality and consistency during commercial production.
