Abstract

Abstract Image

The transamination-chemistry-based process for sitagliptin is a through-process, which challenges the crystallization of the active pharmaceutical ingredient (API) in a batch stream composed of multiple components. Risk-assessment-based design of experiment (DoE) studies of particle size distribution (PSD) and crystallization showed that the final API PSD strongly depends on the seeding-point temperature, which in turn relies on the solution composition. To determine the solution composition, near-infrared (NIR) methods had been developed with partial least squares (PLS) regression on spectra of simulated process samples whose compositions were made by spiking each pure component, either sitagliptin free base (FB), water, isopropyl alcohol (IPA), dimethyl sulfoxide (DMSO), or isopropyl acetate (IPAc), into the process stream according to a DoE. An additional update to the PLS models was made by incorporating the matrix difference between simulated samples in lab and factory batches. Overall, at temperatures of 20–35 °C, the NIR models provided a standard error of prediction (SEP) of less than 0.23 wt % for FB in 10.56–32.91 wt %, 0.22 wt % for DMSO in 3.77–19.18 wt %, 0.32 wt % for IPAc in 0.00–5.70 wt %, and 0.23 wt % for water in 11.20–28.58 wt %. After passing the performance qualification, these on-line NIR methods were successfully established and applied for the on-line analysis of production batches for compositions prior to the seeding point of sitagliptin crystallization.

It can be produced by the body (ie, somatotropin) or genetically engineered (ie, somatropin).
In-Process Control (IPC) In-Process Controls (IPC) are checks performed during production in order to monitor and if necessary to adjust the process to ensure that the product conforms its specification.
Interferons (INFs) Interferons are proteins produced by the body as part of the immune response. They are classified as cytokines, proteins that signal other cells to trigger action. For example, a cell infected by a virus will release interferons to stimulate the defenses of nearby cells.
Interleukins Interleukins are proteins produced by cells as an inflammatory response. Most interleukins help leukocytes communicate with and direct the division and differentiation of other cells.
Investigational Medicinal Product Dossier (IMPD) The Investigational Medicinal Product Dossier (IMPD) is the basis for approval of clinical trials by the competent authorities in the EU. The IMPD includes summaries of information related to the quality, manufacture and control of the Investigational Medicinal Product, data from non-clinical studies and from its clinical use.

Written Confirmation expired: Can an API still be imported when produced earlier?

Posted on Updated on

What needs to be considered if an API is produced in the time period of a valid written confirmation but imported after this confirmation has expired? This is answered in a revised Q&A Document of the EU Commission.

see………http://www.gmp-compliance.org/enews_05432_Written-Confirmation-expired-Can-an-API-still-be-imported-when-produced-earlier_15432,15354,15367,Z-QAMAP_n.html

The EU Commission has updated its Question and Answers Document “Importation of active substances for medicinal products for human use” (now version 7). In this updated version, the question “Can an API batch manufactured during the period of validity of a written confirmation be imported into the EU once the written confirmation is expired?”

In the answer it is referred to Article 46(b)(2)(b) of Directive 2001/83/EC, where it is defined that APIs can only be imported if they are manufactured in accordance with EU GMP or equivalent, and accompanied by a written confirmation from the competent authority of the exporting third country certifying this.

But what if an API is produced in the time period of a valid written confirmation but imported after this confirmation has expired?

In the respective answer the EU Commission states that “it is legitimate to consider that the guarantees of equivalence provided by the written confirmation apply to any API batch in the scope of the written confirmation which was released for sale within the period of validity of the written confirmation, even if not exported in that time period.”

So the answer is ‘yes’, it still can be imported. But it needs to be accompanied by the expired written confirmation together with appropriate documentation which proves “that the whole consignment has been manufactured and released for sale by the quality unit before the expiry date of the written confirmation” and “provides a solid justification of why a valid written confirmation is not available.”

An import without any written confirmation is not possible.
