One of the biggest concerns that the pharmaceutical industry constantly attempts to address is the safety of its products. The term itself encircles many different regulations in many different fields.

GxP stands for "good practice" guidelines and regulations that ensure the safety, effectiveness, and use of drugs.

GxP can relate to a variety of disciplines, including GMP (Good Manufacturing Practice), GDP (Good Distribution Practice), GLP (Good Laboratory Practice), and many others.

They outline the numerous methods that industries in regulated industries are obliged to control their processes, procedures, personnel, and facilities to maintain product consistency and quality.

 

 

GxP assures that regulated businesses follow specific and secure production and storage methods and procedures that define effective nonclinical laboratory experiments and safe human-subject clinical trials. The GxP recommendations are focused on:

 

• Traceability is the ability to recreate a drug's or medical device's development history.

• Accountability: The ability to determine who contributed what and when to the development.

• Data Integrity (DI) is the system's data's trustworthiness. The following activities could be used to determine DI:

Identifying the data that the system generates during crucial processes (data flow diagram)

During the data lifecycle, define the DI requirements (e.g., ALCOA data attributes).

To avoid DI breaches, identify the risks and develop mitigation solutions (e.g., technical or procedural controls).

 

 

Main Purpose of GxP:

 In simple terms, it is a set of guidelines in place to ensure that products and services are safe and effective. To elaborate on this point, GxP enforces regulated industries to stick to very specific and secure manufacturing processes and storage procedures, ensures safe clinical trials involving human subjects, and also establishes effective research standards for non-clinical laboratory trials.

 

 

5 P’s of GxP

§People

Employees have to know their jobs, be trained on them, and follow procedures.

§Procedures

Procedures must be documented, clear, and followed. Any deviations must be documented and investigated.

§Products

Specifications have to be documented and followed. Standard methods for testing, labeling, and packaging must be used.

§Premises

Facilities and equipment have to meet regulatory standards. There must be controls for cleanliness and avoiding cross-contamination.

§Process

Processes must be clearly defined and documented. Change control procedures need to be robust and documented

 

 

 

Why is GxP compliance so important?

Due to the potential risk to the human health of the products they oversee, the powers of the regulators in these sectors are far-reaching.

GxP compliance is monitored and enforced by agencies and government bodies through certification requirements, regular inspections, and unannounced auditing.

In many cases, the scope of the regulator’s remit continues to widen taking in new sectors and product categories. This reflects the extent of innovation in these industries, as well as cross-sector dependencies in the production techniques they use.

For this reason, regulators often require companies to verify and vouch for the GxP compliance of their partners throughout the supply chain.

GxP standards and regulations are found all over the world; some of the most well-known regulators include the FDA in the United States, the TGA in Australia, and the HS-SC in Canada. GxP encompasses several regulatory frameworks, the most prevalent of which are GCP, GLP, and GMP:

 

 

 

Good Clinical Practice (GCP)

Good Clinical Practice is a global standard developed by the International Conference on Harmonization (ICH) that focuses on the ethical aspects of clinical trials, stating that corporate interests should not take precedence over human life in clinical studies involving human participants.

GCP allows industries to adhere to specific standards to ensure that individuals' well-being, rights, and safety are not endangered. All potential dangers must be identified and weighed against the potential benefits.

 

 

Principals of GCP

• Predictable risks and adverse events should be evaluated against the expected benefit to the individual trial subject and society before a trial begins. Only if the expected benefits outweigh the hazards should a trial be started and continued.

• The rights, safety, and well-being of the trial subjects are the most important considerations and should prevail over the interests of science and society.

• Clinical trials should be conducted in a scientifically sound manner and documented in a clear, complete protocol.

• A study should be carried out according to a protocol that has been approved by an institutional review board (IRB) or an independent ethics commission (IEC) and has gotten a favorable opinion.

• Medical treatment for subjects and medical choices made on their behalf should always be under the supervision of a qualified physician or, when appropriate, a certified dentist.

• Each person involved in a trial should be qualified to do his or her job based on his or her education, training, and experience (s).

• Before participating in a clinical experiment, each participant should freely offer their informed consent.

• All clinical trial data should be recorded, processed, and maintained in such a way that correct reporting is possible.

 

 

 

GLP (Good Laboratory Practice)

GLP is the nonclinical counterpart of GCP. These guidelines apply to nonclinical studies conducted for the assessment of the safety or efficacy of chemicals (including pharmaceuticals) to humans, animals, and the environment.

These are a set of guidelines that provide the framework for non-clinical research and specify how it should be conducted, assessed, and reported.

 

 

 

Good Manufacturing Practices (Good Manufacturing Practice)

GMP is a term that refers to the processes that must be followed to comply with the guidelines set forth by the agencies that oversee authorization and licensing for the manufacture and sale of food, drugs, and active pharmaceutical items. These rules establish basic standards that a pharmaceutical or food product maker must fulfill to ensure that the products are of high quality and do not constitute a risk to consumers or the general public. Regulatory agencies in the United States, Canada, Europe, China, and other nations monitor good manufacturing procedures, as well as good laboratory practices and good clinical practices.

Rules and interpretations differ from country to country (and change frequently) but all GMP requires that products

• are of consistently high quality;

• are appropriate for their intended use;

• Meet the requirements of the marketing authorization or clinical trial authorization.

 

 

 

Good Documentation Practices (GDP)
GDP is the minimum standard that a wholesale distributor must meet to ensure that the quality and integrity of medicines are maintained throughout the supply chain
