Remove Clinical Trials Information from KG2

[ecwood]

Per the discussion in the AHM today, we need to figure out what (if any) clinical trials information is currently in KG2.

[ecwood]

#398 will replace this information

[ecwood]

Based on match (n:`biolink:RetrievalSource`) where not n.id =~ 'umls_.*' and not n.id =~ 'OBO:.*' return n.id, n.name order by n.id; RepoDB is not in KG2.10.1pre.

Further,

match (n)-[e]->(m) where e.predicate="biolink:applied_to_treat" and e.primary_knowledge_source="infores:chembl" return count(e)

returned no results, suggesting that the clinical trials information from chembl has been removed.

Closing this issue.
