Resolving EMA source product links in Clinical indications widget

[prashantuniyal02]

Currently the implementation is set to link to the EMA medicines browser landing page which we want to improve at a later stage.

Background

EMA. Not trivial, the reference is full in the evidence set but not here. For CHEMBL4297551:

• Evidence has the full link https://www.ema.europa.eu/en/medicines/human/EPAR/vyvgart
• Indications dataset has an EMA product number EMEA/H/C/005849

It's easy to find the EMA page if you google the product number, but they're indexed by their commercial name. There is not a reliable and direct way to build this link for us. I have 3 suggestions in order of preference:

• To extract the link available in the evidence. The ideal, but cumbersome.
• To link to the search page of the browser when you search for the drug name (this takes a while). For the above example, it'd be https://www.ema.europa.eu/en/search?f%5B0%5D=ema_search_categories%3A83&f%5B1%5D=ema_search_categories%3A84&f%5B2%5D=ema_search_categories%3A85&f%5B3%5D=ema_search_content_type%3Aema_herbal&f%5B4%5D=ema_search_content_type%3Aema_medicine&f%5B5%5D=ema_herbal_and_authorised_medicines%3AHerbal%20and%20authorised%20medicines&search_api_fulltext=EFGARTIGIMOD%20ALFA
• To link to the EMA medicines browser landing page

It would be great to talk to ChEMBL at some point and see how they resolve the links to EMA in the Drug Indications table. The best approach would be to get direct links as part of the evidence.

I removed the FE label because, after discussing this with @prashantuniyal02 in the FE team, we agree it is a data issue.
