Final Revised Good Agricultural and Collection Practice (GACP) Guideline Published: What You Need to Know About Revision 1

**Posted on August 28, 2025**

Hello, GMP compliance enthusiasts! If you're involved in the world of herbal medicinal products, you've likely been keeping an eye on updates from the European Medicines Agency (EMA). The big news is that the Committee on Herbal Medicinal Products (HMPC) has finally adopted Revision 1 of the *Guideline on Good Agricultural and Collection Practice (GACP) for Starting Materials of Herbal Origin*. This update replaces the original guideline from 2006, bringing it in line with modern practices and technologies.

In this blog post, we'll break down the key changes in Revision 1 in simple terms. We'll focus on why this revision matters, what's new (especially for indoor cultivation), and how it impacts everyone from growers to manufacturers. Whether you're a cultivator, collector, or quality assurance professional, this guide will help you understand how to ensure the safety and quality of herbal starting materials. Let's dive in!

## Why Was the GACP Guideline Revised?

The original GACP guideline came into effect in August 2006 to ensure consistent quality for herbal substances used in medicines. Herbal medicines are complex—think plants like chamomile or ginseng—and their quality can be affected by everything from how they're grown to how they're harvested.

Over the past decade-plus, things have evolved:

- **Technological advances**: Indoor growing (like in controlled environments) has exploded in popularity. This allows better control over factors like light and humidity but brings new challenges.

- **Legal and practical updates**: Interpretations from documents like Annex 7 of the EU GMP Guidelines (from 2009) on manufacturing herbal products have been incorporated.

- **Patient safety focus**: With more awareness of contaminants (e.g., heavy metals, pesticides, or toxic weeds), the guideline now emphasizes reducing risks at every step.

Revision 1 keeps the core goal: establishing a quality assurance system for cultivation, collection, harvesting, and primary processing. It applies to all players in the supply chain—cultivators, harvesters, collectors, traders, processors, and manufacturers. For organic production, it overlaps with EU Regulation 2018/848, but GACP adds specific recommendations for medicinal plants.

The guideline stresses that wild collection vs. cultivation (outdoor, greenhouse, or indoor) each has pros and cons. For example, wild plants might vary more in composition, while cultivated ones offer better control but require careful management to avoid contamination.

## Key Sections of the Guideline: What's Stayed the Same and What's New?

The structure remains similar to the 2006 version, covering topics like quality management, personnel training, equipment, and more. But Revision 1 adds depth, especially on documentation, contamination prevention, and environmental considerations. Here's a breakdown, focusing on revisions:

US FDA WL to Indian pharm company after fire accident

Access WL

The recent FDA warning letter to an Indian manufacturer of active pharmaceutical ingredients (APIs) highlights major Good Manufacturing Practice (GMP) violations, particularly regarding the handling of fire-affected API batches and significant deficiencies within the company’s stability program[1].

## Regulatory Findings: GMP Breaches

During the FDA’s inspection in September 2024, the agency discovered that multiple API batches stored in warehouse areas directly impacted by a fire in December 2022 were released and exported to the U.S. market[1]. These products had been exposed to severe environmental conditions such as heat and smoke, yet the company’s Quality Unit approved their release without initiating a recall, despite internal records confirming the adverse impact of the fire[1]. The FDA deemed the company’s retrospective assessment inadequate and emphasized that pharmaceuticals exposed to uncontrolled conditions should be considered **adulterated** and are not permissible for U.S. distribution[1]. Additionally, there was no commitment from the manufacturer to address other potentially impacted batches identified in post-incident documentation[1].

## Stability Program Gaps

The FDA also identified severe shortcomings in the manufacturer’s stability program[1]. Over the previous two years, repeated power outages—some lasting up to 40 hours—compromised storage chamber conditions. The absence of data loggers meant temperature and humidity changes during outages were not recorded[1]. While the manufacturer acknowledged these weaknesses and promised further temperature-assessment studies during power failures, there was no comprehensive study protocol, formal risk assessment, or effective measures to stabilize electrical supply — all critical requirements for ensuring GMP compliance[1].

## Regulatory Guidance

The FDA referenced existing guidance documents for handling pharmaceutical products or components exposed to substandard storage conditions, especially as a result of natural disasters or facility incidents[1]. Notably, the agency stressed that failing to adhere to these established protocols threatens drug safety and quality, posing risks to patient health[1].

## Industry Context and Upcoming Events

GMP professionals may benefit from upcoming industry events spotlighting compliant site transfers, granulation & tableting technology, and advanced visual inspection methods. Conferences in Barcelona and Vienna during September–October 2025 will provide in-depth guidance on these topics[1]. Recent related news includes updates to pharmaceutical water standards, cleanroom guidelines, and advances in compaction simulation — all reflecting evolving regulatory expectations for drug manufacturers[1].

This warning letter serves as a strong reminder of the regulatory scrutiny and operational rigor required to maintain global pharmaceutical supply chain integrity and public health[1].

The United States Food and Drug Administration (FDA) issued a warning letter to Glenmark Pharmaceuticals Limited on July 11, 2025, following an inspection of their drug manufacturing facility located at Phase – II, Sector III, Plot No 2, Pharma Zone, SEZ, Pithampur, Madhya Pradesh, India, conducted from February 3 to 14, 2025. The FDA’s inspection revealed significant violations of Current Good Manufacturing Practice (CGMP) regulations for finished pharmaceuticals, as outlined in Title 21 of the Code of Federal Regulations (CFR), parts 210 and 211. These violations indicate that Glenmark’s methods, facilities, and controls for manufacturing, processing, packing, and holding drug products do not comply with CGMP standards, rendering their drug products adulterated under section 501(a)(2)(B) of the Federal Food, Drug, and Cosmetic Act (FD&C Act), 21 U.S.C. 351(a)(2)(B). This letter underscores the FDA’s commitment to ensuring that pharmaceutical products meet stringent quality and safety standards to protect public health. Below, we elaborate on the key findings, their implications, and the FDA’s expectations for corrective action, tailored for pharmaceutical professionals to understand the regulatory intent and necessary compliance measures.

### Key Violations Identified by the FDA

1. **Inadequate Cross-Contamination Prevention Strategies**  

   During the inspection, FDA investigators observed that Glenmark was manufacturing drug products containing a specific active pharmaceutical ingredient (API) (redacted as (b)(4) in the warning letter) using shared equipment and air handling units alongside other drug products. While complete facility separation is not mandatory for such manufacturing, the FDA emphasizes the need for robust strategies to prevent cross-contamination, such as dedicated production suites or validated cleaning procedures. The absence of adequate controls increases the risk of unintended API residues contaminating other products, potentially compromising patient safety.

   **FDA’s Intent**: The FDA is signaling that manufacturers must implement stringent controls to prevent cross-contamination, especially when handling potent or sensitizing compounds. This aligns with CGMP requirements under 21 CFR 211.67 (Equipment Cleaning and Maintenance) and 21 CFR 211.42 (Design and Construction Features), which mandate that equipment and facilities be designed and maintained to prevent contamination. The FDA acknowledges Glenmark’s decision to discontinue manufacturing these specific drug products but requires a detailed cross-contamination prevention plan if production resumes, emphasizing proactive risk management.

2. **Delayed Stability Sample Testing and Inadequate Response**  

   The inspection revealed a backlog of pending stability sample testing, which is critical for ensuring that drug products maintain their quality, safety, and efficacy throughout their shelf life. Glenmark’s response to the FDA’s Form 483 (issued post-inspection) outlined the root causes for these delays, including insufficient quality control (QC) laboratory capacity. The company claimed that all delayed stability testing for U.S. commercial products was completed by December 2024 and described plans to enhance QC resources, such as increasing laboratory capacity, purchasing additional equipment, and hiring personnel. Additionally, Glenmark implemented oversight mechanisms to monitor stability testing progress. However, the FDA deemed the response inadequate because it lacked critical details, such as the test results from the delayed stability analyses and a comprehensive investigation report identifying root causes and corrective actions.

   **FDA’s Intent**: The FDA is emphasizing the importance of timely and robust stability testing under 21 CFR 211.166 (Stability Testing of Drug Products). Stability data are essential to confirm that drugs remain within specifications under labeled storage conditions. By highlighting the absence of test results and investigation details, the FDA is reinforcing that manufacturers must provide transparent, evidence-based responses to demonstrate compliance. This also reflects the agency’s expectation for proactive resource planning to prevent testing backlogs, which could delay the detection of product quality issues.

3. **Systemic CGMP Failures Across Glenmark’s Network**  

   The warning letter notes that similar CGMP violations were previously identified at other Glenmark facilities, indicating systemic deficiencies in the company’s quality management system. For instance:

   - **Himachal Pradesh, India Facility (FEI 3005757050)**: A 2019 warning letter cited violations of 21 CFR 211.192 for inadequate investigations into out-of-specification (OOS) test results for critical product attributes, such as failed assays in a cream product.

   - **Goa, India Facility (FEI 3004672766)**: A 2022 warning letter highlighted inadequate investigations into OOS results for content uniformity testing of desmopressin acetate tablets.

   - **North Carolina, U.S.A. Facility (FEI 3011585599)**: A 2023 warning letter addressed various CGMP violations, further evidencing recurring issues.

   These repeated failures across multiple sites suggest that Glenmark’s executive management has not adequately overseen or controlled manufacturing operations to ensure consistent CGMP compliance.

   **FDA’s Intent**: By referencing violations at multiple sites, the FDA is underscoring that compliance is a corporate-wide responsibility. The agency expects executive management to conduct a comprehensive assessment of global manufacturing operations to identify and resolve systemic deficiencies. This aligns with 21 CFR 211.180 (General Requirements) and 21 CFR 211.192 (Production Record Review), which require robust quality systems to ensure consistent product quality. The FDA’s focus on systemic issues signals its intent to hold companies accountable for fostering a culture of compliance across all facilities.

### Broader Implications and FDA Expectations

The FDA’s warning letter serves as both a corrective directive and a broader warning to the pharmaceutical industry about the importance of adhering to CGMP standards. The violations identified at Glenmark’s Pithampur facility—cross-contamination risks, delayed stability testing, and systemic quality failures—highlight common areas of concern that can compromise drug safety and efficacy. The FDA’s intent is clear:

- **Protect Patient Safety**: Non-compliance with CGMP standards, such as inadequate contamination controls or delayed testing, can lead to substandard or unsafe drugs reaching patients. The FDA prioritizes public health by enforcing rigorous manufacturing standards.

- **Demand Accountability**: By citing violations across multiple Glenmark facilities, the FDA is holding the company’s leadership accountable for ensuring global compliance. This includes implementing effective quality systems and oversight mechanisms.

- **Encourage Proactive Remediation**: The FDA expects Glenmark to address the specific violations (e.g., cross-contamination prevention and stability testing) and conduct a holistic review of its operations to prevent recurrence. This includes submitting detailed corrective action plans within specified timelines (typically 15 working days).

### Recommended Actions for Glenmark and Pharmaceutical Professionals

To address the FDA’s concerns and restore compliance, Glenmark must take the following steps, which also serve as guidance for pharmaceutical professionals managing similar issues:

1. **Develop a Cross-Contamination Prevention Plan**: If Glenmark resumes manufacturing the implicated drug products, it must submit a detailed plan outlining cleaning validation, equipment segregation, and air handling controls to prevent cross-contamination. This should include risk assessments and scientific justification for the chosen controls.

2. **Strengthen Stability Testing Processes**: Glenmark should provide the FDA with complete stability test results, investigation reports, and a corrective action plan to prevent future backlogs. This may involve increasing QC laboratory capacity, automating testing processes, and establishing robust oversight mechanisms.

3. **Conduct a Global Compliance Assessment**: Executive management should perform a comprehensive audit of all manufacturing sites to identify and address systemic CGMP deficiencies. This includes enhancing quality systems, training personnel, and ensuring adequate resources for compliance.

4. **Respond Promptly and Transparently**: Glenmark must submit a detailed response to the FDA within 15 working days, addressing each violation with specific corrective actions, timelines, and supporting data. Transparency and thoroughness are critical to demonstrating commitment to compliance.

### Conclusion

The FDA’s warning letter to Glenmark Pharmaceuticals Limited reflects its unwavering commitment to enforcing CGMP regulations to ensure the safety, quality, and efficacy of pharmaceutical products.
