Yes, you are correct. PMCB has been on the list for at least 2 years. The 1/3/20 is the last time the list was updated which is monthly.There are 8754 companies listed on the SRO list including large companies and penny stocks (other otc market) and some could be sub penny stocks if anyone wants to check the list on the link below.

All companies that do not have a record of sales of FDA-regulated products will be deemed to be significantly regulated if its operations are predominately in fields regulated by FDA, which PMCB is. If any announcement comes out it is just coincidental.There is also a statement saying " or if its research, development, or other business activities are reasonably expected to result in the development of products that are regulated by FDA"which just means since PMCB is working on a potential product involving Pancreatic Cancer it also falls in this category.
