Q:

Drug label information does not include all approved drugs (kymriah and yescarta missing)

It appears as though some drug labels are missing.   I just want to know if I'm missing something obvious? 
Specifically I cannot find either Kymriah or Yescarta searching by their brand or generic name.   Both drugs were approved in 2017.   I have downloaded the complete label dataset from https://download.open.fda.gov/drug/label/drug-label-000X-of-0007.json.zip and confirm that neither terms appear in the complete dataset at all.  
Example search:
https://api.fda.gov/drug/label.json?api_key=XXXX&search=kymriah
edit: I have confirmed that the kymriah label XML files are present on the SPL S3 bucket:
s3://download.open.fda.gov/data/spl/11dc1c28-0cf5-4290-b499-eb5391a232c2
s3://download.open.fda.gov/data/spl/22dc1c28-0cf5-4290-b499-eb5391a232c2

To expand Denis Krylov's answer. 
The SPL processing pipeline uses SPLDocuments.csv as the master list for drugs to process and import into OpenFDA.   The file can be retrieved as follows:
aws s3 cp s3://download.open.fda.gov/data/spl/change_log/SPLDocuments.csv . 
If we were to execute:
head SPLDocuments.csv
We would get something like the following:
"Document Id","Document Type","Load Time"
7b8f583f-8df4-4aea-bec8-206598ecfefe,"HUMAN PRESCRIPTION DRUG LABEL",20180402100037
bac17f46-9dfa-4e00-a047-02067e450f84,"Indexing - Substance",20170928145900
The SPL processing pipeline only takes items that contain 'human' in the second column (document type).   As of today, there are 18 products which contain "cellular therapy" as the document type.   These are currently ignored by openfda, although its not clear if this is by design or not. 

A:

Cell therapy drugs aren't indexed by openFDA.  Please see the relevant code here: https://github.com/FDA/openfda/blob/master/openfda/spl/pipeline.py#L90
