Pharma companies need to be always updated with the latest sfda variation guidelines to ensure compliance with the drug life cycle management regulations in Saudi Arabia. The SFDA is continuously updating its way of accepting and evaluating drug variation submissions. To keep up with that, regulatory professionals have to follow the latest versions of the SFDA Variation Guidelines ( also published as GCC variation guidelines).
As known, the variation file is a request from the MAH to the SFDA to change or update the registered drug information. It is a post-approval regulatory procedure that is frequently takes place after the SFDA drug registration to ensure that the amendments on the registered drug file are approved for marketing.
We will in this post discuss the latest version (Guidelines for Variation Requirements v 6.1).
SFDA Variation Guidelines
The sfda variation guidelines describe the types of variations and the requirements for their submission to update the registered drug file. It covers the administrative and CMC changes for manufacturers, MAH, API, and drug products.
The changes vary from low to high potential risks concerning product quality. The manufacturer is encouraged to utilize a risk-based regulatory processes system for;
(a) requesting approval for any major changes from the regulatory authority before implementation.
(b) notifying the regulatory authority of minor changes after implementation.
The above system includes the following categories for regulatory communications with one or more levels in each category according to when we need to notify SFDA of any post-approval changes.
In the sfda variation guidelines, there are types of variations that do not require prior approval. They are moderate to low-risk changes without a high impact on the product’s quality, safety, and efficacy. According to the guidelines, these changes are communicated to the regulatory authority as a formal notification that takes place within a defined period before or after implementation.
On the other hand, the SFDA variation guidelines identified major changes that require approval before implementation. They are with heavy impact on the quality, safety, and efficacy of the product. Therefore, the MAH should submit a detailed eCTD dossier to describe and justify the variation. Note that the approval might require an SFDA GMP inspection for some variation types, such as when resourcing from a new manufacturing site.
Types of SFDA Drug Variations
We can notice in the SFDA variation guidelines version 6.1 that the SFDA had introduced a new type called IAIN. It becomes between type IA and IB, and it is too considered a minor variation.
In the below section, we will detail all the variation types:
Type IA Variation
Such minor variations do not require prior approval before implementation, it is called the “Do and Tell” procedure. Type IA variations, however, can be compiled in a single variation application to be submitted to the SFDA no later than January 31st of each year. The variation application for every product should indicate:
- All IA variations have been implemented during the previous year.
- Date of implementation of each variation.
Type IAIN Variation
Should be submitted immediately, within a maximum of 14 days after implementation. Note that it is possible to group IA with IAIN variations as follows:
Grouping Type IA/IAIN changes
Type IA or IAIN variation can be grouped for one medicinal product or affect several medicinal products from the same MAH.
Grouping Type IA/IAIN with other types of variations
Type IA/IAIN can also be grouped with other variations like Type IB and Type II. Such grouped submissions will follow the review timeline of the highest variation in the group.
Under this type of variation falls the changes that are neither Type IA nor Type II. This means that the change can be considered Type IB when Type IA conditions are not met and the change is not listed as one of the Typed II major changes.
Type IB variations must be submitted to the authority by MAH before implementation, but it does not require formal approval. However, the MAH must wait 60 working days to ensure that the application is deemed acceptable before implementing the change (“Tell, Wait and Do” procedure).
Grouping Minor (IB) Variations
It is also possible for a MAH to group a Type IB variation with other variation(s) for the same product, like Type IA and Type II. Such grouped submissions will follow the review timeline of the highest variation in the group.
These are the major variations that may significantly impact the Quality, Safety, or Efficacy of a medicinal product and require prior approval before implementation. For this major type, there are no specific documents or requirements by SFDA. For example, if the change is in a manufacturing site, a whole module 3 needs to be resubmitted with the variation.

Unaccepted Variations (Requires New Application)
Some major changes are too essential to be considered as variations.
The SFDA does not accept some changes on the registered file as a variation since they are too substantial to review as an update on a registered file. Therefore, they are required to be filed in a new registration submission for an independent review. Examples of those changes are:
- Changing the API with a different API.
- Addition of an API in a multi-component product.
- Removal of an API from a multi-component product.
- Change in the dose of APIs.
- Change in the dosage form, e.g., changing the dosage form from an immediate-release product to a slow- or delayed-release dosage form and vice versa.
- Change in the pharmaceutical form, e.g., changing from a liquid to a powder for reconstitution, or vice versa.
- A change from multi-dose to single-dose or vice-versa (both for addition or replacement).
- Change in the strength of the finished product.
- Change in the route of administration or addition of route of administration.
SFDA Variation File Format
The variation submission must be in eCTD format and include all the affected files by the new change. Companies do not have to include the full copy of the dossier. Only the must include in addition to the affected sections of the dossier.
The SFDA started charging for variation submission in 2021. Companies must settle a governmental invoice through the SADAD system for every variation application. SFDA collects the fees per registered pack. For the variation fee amount, refer to our article SFDA Fees.
