GUIDELINE INDEX. BATCH Q: Quality. Finalised Guidelines (Step 4). Q1A(R2). Stability Testing of New Drug Substances and Products (Second Revision). Feb. Implication of the use of ICH guidelines by non-ICH drug regulatory . in the area of pharmacovigilance, and all ICH countries should be encouraged to. Download as PDF, TXT or read online from Scribd All Know all ICH guidelines for quality in pharmaceutical as Q1A, Q1B, Q1C, Q1D, Q1E, Q1F, Q2( R1).

This study should include the effect of temperature in 10 degree increments e. The testing should also evaluate the susceptibility of the API to hydrolysis across a justified range of pH values when in solution or suspension.

It is important to understand that these onetime stress studies on a single product batch are not considered part of the formal stability study program.

Phase 3 stability studies are often used as the registration stability study but they can be separate studies. To ensure that appropriate data are generated for product registration at the New Drug Application NDA stage, a formal stability protocol needs to be developed that satisfies all regulatory requirements. Various analyses have been conducted to identify suitable testing conditions for WHO Member States based on climatic data, to enable each Member State to decide on long-term real-time stability testing conditions.

Compared to ICH stability guidelines, the WHO guideline also provides additional guidance including recommendations on test parameters, storage statements and labelling, coverage for both new and established drug products, and the interpretation of storage statements for products approved in Climatic Zone II, but intended for distribution in Climatic Zone IV.

A new WHO stability guideline8 was published in June which replaced the guideline. Readers are encouraged to consult the new guideline when considering global registration. Stability Protocol A formal stability protocol is not required for development and clinical stability studies. It becomes a regulatory and compliance document from registration stability and commercial stability.

The results of such stability testing shall be used in determining appropriate storage conditions and expiration dates. The written program shall be followed and shall include: 1 Sample size and test intervals based on statistical criteria for each attribute examined to assure valid estimates of stability; 2 Storage conditions for samples retained for testing; 3 Reliable, meaningful, and specific test methods; 4 Testing of the drug product in the same container closure system as that in which the drug product is marketed; 5 Testing of drug products for reconstitution at the time of dispensing as directed in the labeling as well as after they are reconstituted.

Container closures, test methods and specifications, storage conditions and test intervals should all be specified, as should a sampling plan, the data reporting and statistical procedures to be employed, the sign-off and change control procedures to be used, and the proposed expiration dating period for the product. Batch Selection for Product Registration Stability studies should be performed on each individual dosage strength and container size of a drug product unless bracketing or matrixing is applied.

At least three primary batches of the final formulation manufactured using the same process simulating the final commercial manufacturing process should be tested.

These batches should also adhere to the same quality standards and meet the same specifications as the proposed commercial drug product and they should also be contained in the same CCS as proposed for marketing the drug product.

At least two of the three batches should have been manufactured at pilot scale and be based on different batches of the API of the drug. For solid dosage forms, pilot scale is at least one-tenth of full production scale or , tablets or capsules, whichever is the larger.

Stability Data at Submission Based on the data and product understanding, a sponsor should provide: proposed expiration dating period and justification, proposed label storage condition and justification, proposed in-use label storage condition and in-use time period and justification, if applicable.

Best practices in following ICH guidelines for APIs

Stability Commitment Where long-term stability data on primary batches do not cover the proposed shelf life granted at the time of approval, a commitment should be made to continue the stability studies post approval in order to firmly establish the shelf life: Submission data from three production batches: continue long term study through proposed shelf-life; Submission data from less than three production batches: set more production batches on to make up the three required, using the same protocol; Submission data not from production batches: first three production batches to set on stability through proposed shelf-life long term, and for six months in accelerated conditions.

Stability Studies Post Approval After approval, sponsors are required to undertake stability studies on at least one lot per strength and per packaging configuration under long-term conditions each year as the product is manufactured.

These studies are referred to as annual stability or commercial stability, and are conducted to monitor product quality. Sponsors can, through a Prior Approval Supplement, discontinue the annual testing point from standard ICH, and can use the annual stability data to extend product expiry through an annual report.

The importance of Good Clinical Practice guidelines and its role in clinical trials

Due to the time lag between product manufacturing and stability initiation, it is recommended to add an expiry test point. Additional stability testing three or six months long-term and accelerated may be required to support post approval changes in manufacturing process, composition in formulation, immediate packaging and manufacturing of APIs. Conclusion Whether conducted in-house by a pharmaceutical company, or outsourced, stability testing is a crucial step in the drug approval process, and assesses how the quality of a drug substance or drug product, and its packaging, will vary over time under the influence of environmental factors such as heat, exposure to light and humidity.

The process determines whether any physical, chemical or microbiological changes may affect the efficiency and integrity of the final product, thereby ensuring its safety and efficacy when prescribed.

Moreover, stability testing establishes the shelf life and recommended storage conditions of a finished pharmaceutical product and the retest periods for a drug substance. Q1A - Q1F Stability.

This new Guideline is proposed to: Q14 Analytical Procedure Development.It advises on the types of information that are considered valuable in assessing the structure of the expression construct used to produce recombinant DNA derived proteins. Research-related risks must be reasonable in light of the expected benefits. May Accelerate your API manufacturing project Questions? The written program shall be followed and shall include: 1 Sample size and test intervals based on statistical criteria for each attribute examined to assure valid estimates of stability; 2 Storage conditions for samples retained for testing; 3 Reliable, meaningful, and specific test methods; 4 Testing of the drug product in the same container closure system as that in which the drug product is marketed; 5 Testing of drug products for reconstitution at the time of dispensing as directed in the labeling as well as after they are reconstituted.

Regulatory Requirements during Clinical Phase The regulatory requirements of stability studies to support clinical trials are very limited. It means the API will be sufficiently free of impurities and consequently safe for patients to take, starting with Phase I clinical trials.

In addition, this annex describes the principles of quality by design QbD. As well, the risks associated with even miniscule amounts of an impurity must be determined. Contact Log In.
