Ensuring the quality, safety, and efficacy of pharmaceutical products is essential for gaining regulatory approval and bringing a new drug to market. Chemistry, Manufacturing, and Controls (CMC) is a fundamental component of drug development, providing the necessary data to demonstrate that a drug can be consistently manufactured and remains stable throughout its lifecycle.
Regulatory agencies worldwide, including the Food and Drug Administration (FDA) in the US, the European Medicines Agency (EMA), the Pharmaceuticals and Medical Devices Agency (PMDA) in Japan, and the Therapeutic Goods Administration (TGA) in Australia, require detailed CMC documentation as part of the drug approval process.
In Australia, many pharmaceutical companies choose to conduct First-in-Human (FiH) and Phase I clinical trials due to the efficient regulatory framework and cost-effective trial environment. However, before these trials can commence, Ethics Committee (EC) approval is required. This article explores why CMC is critical for regulatory success, focusing on its role in global regulatory submissions and the EC approval process in Australia.

What is CMC in Drug Development?
CMC refers to the scientific and regulatory framework that ensures pharmaceutical products are developed, manufactured, and tested in a consistent and reproducible manner. It covers:
- Drug Substance (Active Pharmaceutical Ingredient, API) – Source, synthesis, purity, and stability.
- Drug Product (Final Formulation) – Composition, excipients, and quality attributes.
- Manufacturing Process and Controls – Good Manufacturing Practice (GMP) compliance and process validation.
- Analytical Methods and Stability Testing – Ensuring drug quality and shelf-life.
Without robust CMC data, regulatory agencies cannot assess the quality, safety, and consistency of an investigational drug.
CMC Requirements for Regulatory Submission
CMC data is required for regulatory submissions worldwide, including:
- FDA (United States) – Investigational New Drug (IND) application, New Drug Application (NDA), and Biologics License Application (BLA).
- EMEA (Europe) – Clinical Trial Application (CTA) and Marketing Authorisation Application (MAA).
- PMDA (Japan) – Investigational Clinical Trial Notifications (CTN) and drug approval dossiers.
- TGA (Australia) – Clinical Trial Notification (CTN) and Clinical Trial Exemption (CTX) schemes.
Each regulatory body mandates extensive CMC documentation to ensure product safety, quality, and manufacturing consistency before approving a drug for clinical trials or market authorisation.
Ethics Committee (EC) Approval for Clinical Trials in Australia
In Australia, regulatory approval for early-phase clinical trials (FiH, Phase I) follows a different approach than in the US and Europe. Instead of requiring direct approval from the TGA, clinical trials must first receive Ethics Committee (EC) approval.
The Human Research Ethics Committee (HREC) reviews applications based on the National Statement on Ethical Conduct in Human Research and TGA guidelines. FiH trials undergo additional scrutiny due to the higher risk associated with first-time human exposure.
Key Steps in the EC Application Process
1. Ethics Application Submission
- Submit the application to a Human Research Ethics Committee (HREC).
- For multi-site trials, a Single-Ethics Review Committee (Lead HREC) can grant approval for multiple trial locations.
2. Required Documents for EC Application
A complete EC submission must include:
- Study Protocol – A detailed document outlining study design and methodology.
- Informed Consent Form (ICF) – Explains the trial’s risks and procedures to participants.
- Investigator Brochure (IB) – Summarises preclinical and clinical data on the investigational product.
- Safety Reporting Plan – Defines procedures for reporting adverse events (AEs) and serious adverse events (SAEs).
- Clinical Trial Registration – Proof of registration with the Australian New Zealand Clinical Trials Registry (ANZCTR).
- CVs of Investigators – Credentials of the principal investigator and key researchers.
- Risk Assessment – Evaluates the risk-benefit profile of the investigational drug.
- Insurance Details – Demonstrates indemnity and insurance coverage for trial participants.
- Ethics and Good Clinical Practice (GCP) Compliance – Adherence to NHMRC (National Health and Medical Research Council) guidelines.
- Data and Safety Monitoring Plan – Describes how the trial will be monitored for safety.
3. Review of FiH Trials
- FiH trials often undergo additional scrutiny due to the novel nature of the investigational product. There may be a pre-submission meeting with the HREC, where sponsors can discuss their proposed study in detail.
- Ethics committees may request additional details regarding the pre-clinical safety data and potential risks specific to FiH trials before granting approval

CMC Data Requirements for EC Approval
Ethics Committees require CMC documentation to ensure that the investigational drug is safe for human use and manufactured according to GMP standards. The key requirements include:
1. Manufacturing Information
- Description of drug substance and drug product.
- Manufacturing process, purification steps, and excipient details.
- Batch records and validation documentation.
2. Quality Control and Stability Testing
- Stability data under various storage conditions.
- Batch release testing results for purity, potency, and sterility.
If you require stability testing solutions, explore our ICH Stability services.
3. Pharmaceutical Formulation and Dosage
- Drug formulation details (e.g., tablet, injectable, topical).
- Dosage and administration guidelines.
4. Toxicology Data
- Preclinical safety data, including acute toxicity and genotoxicity.
5. GMP Compliance and Risk Management
- Evidence of GMP manufacturing practices.
- Risk management strategies for quality and safety concerns.
Key Takeaways:
Why CMC Data Matters for EC Approval
- CMC data is required globally – Not just for FDA submissions, but also EMA, PMDA, and TGA approvals.
- Australia’s clinical trial approval process is unique – Ethics Committee (EC) approval is required before FiH and Phase I trials can begin.
- CMC documentation is essential for EC applications – Ensures the investigational product meets safety, stability, and GMP compliance requirements.
- FiH trials require additional scrutiny – Risk assessments and preclinical safety data are critical for gaining approval.
For companies planning early-phase trials in Australia, preparing detailed CMC documentation is crucial for regulatory success and expedited approvals.
Final Thoughts
CMC is a critical component of drug development, ensuring that investigational products are manufactured consistently, comply with regulatory guidelines, and meet stringent safety requirements.
In Australia, gaining Ethics Committee (EC) approval is an essential step before commencing FiH and Phase I clinical trials. Properly prepared CMC documentation ensures a smooth submission process and faster trial initiation.
