CERTIFICATE OF GMP COMPLIANCE OF A MANUFACTURER(1) , (2)

Part 1

Issued following an inspection in accordance with
Art. 111(5) of Directive 2001/83/EC as amended

The competent authority of Netherlands confirms the following:

The manufacturer: Katwijk Chemie B.V.

Site address:

Snijderstraat 6, Katwijk Zh, 2222 BA, Netherlands

OMS Organisation Id. / OMS Location Id.: ORG-100019011 / LOC-100027776

Is an active substance manufacturer that has been inspected in accordance with Art. 111(1) of Directive 2001/83/EC1 transposed in the following national legislation:Art. 100 of the Medicines Act.

From the knowledge gained during inspection of this manufacturer, the latest of which was conducted on 2024-09-26 , it is considered that it complies with:

The principles of GMP for active substances referred to in Article 47 of Directive 2001/83/EC and an appropriate level of GMP as referred to in Article 46(f) of Directive 2001/83/EC transposed in the following national legislation:Art. 100 of the Medicines Act.

This certificate reflects the status of the manufacturing site at the time of the inspection noted above and should not be relied upon to reflect the compliance status if more than three years have elapsed since the date of that inspection. However, this period of validity may be reduced or extended using regulatory risk management principles by an entry in the Restrictions or Clarifying remarks field. Updates to restrictions or clarifying remarks can be identified through the EudraGMDP website (https://eudragmdp.ema.europa.eu/). This certificate is valid only when presented with all pages and both Parts 1 and 2.

The authenticity of this certificate may be verified in EudraGMDP. If it does not appear, please contact the issuing authority.
