1.1. Submission of the dossier

The applicant AstraZeneca AB submitted on 11 January 2021 an application for marketing authorisation to the European Medicines Agency (EMA) for COVID-19 Vaccine AstraZeneca, through the centralised procedure falling within the Article 3(1) and point 1 of Annex of Regulation (EC) No 726/2004. The eligibility to the centralised procedure was agreed upon by the EMA/CHMP on 9 June 2020.

The applicant applied for the following indication:

“COVID-19 Vaccine AstraZeneca is indicated for active immunisation to prevent COVID 19 caused by SARS-CoV-2, in individuals 18 years of age and older.

The use of this vaccine should be in accordance with official recommendations”.

The legal basis for this application refers to:

Article 8.3 of Directive 2001/83/EC - complete and independent application

The application submitted is composed of administrative information, complete quality data, non-clinical and clinical data based on applicants’ own tests and studies and/or bibliographic literature substituting/supporting certain tests or studies.

Information on Paediatric requirements

Pursuant to Article 7 of Regulation (EC) No 1901/2006, the application included an EMA Decision P/0003/2021 on the agreement of a paediatric investigation plan (PIP).

At the time of submission of the application, the PIP P/0003/2021 was not yet completed as some measures were deferred.

Information relating to orphan market exclusivity

Similarity

Pursuant to Article 8 of Regulation (EC) No. 141/2000 and Article 3 of Commission Regulation (EC) No 847/2000, the applicant did not submit a critical report addressing the possible similarity with authorised orphan medicinal products because there is no authorised orphan medicinal product for a condition related to the proposed indication.

Applicant’s requests for consideration

Conditional marketing authorisation

accordance with Article 14-a of the Regulation (EC) No 726/2004.

New active Substance status

The applicant requested the active substance Chimpanzee adenovirus vector encoding the SARS-CoV-2 spike glycoprotein (ChAdOx1-S)contained in the above medicinal product to be considered as a new active

substance, as the applicant claims that it is not a constituent of a medicinal product previously authorised within the European Union.
