I guess everyone agrees and there is no certainty in the
stock market, especially in the biotech sector and worse in betting for a FDA
decision! Unfortunately we got a real time example today with PTLA that I was
expecting an approval yesterday. Instead, PTLA got a so-called complete
response letter (CRL). In the biopharma jargon, a CRL means a non-approval
decision, which will list what else the FDA is requesting for further
consideration. One of the worse requests is new data that must be collected
from clinical trials since such data will take years to provide. The CRL PTLA
got seems not so bad as the key missing information is about some manufacturing
issues and some details about the 2 anticoagulants that Andexxa is supposed to
counteract. Without knowing details, my guessing is that this kind of
information can usually be provided fairly soon. Given that the FDA did not
question its efficacy and safety, I think it virtually told PTLA that this drug
is approvable but just need a bit more time. Personally I think this gives
another better opportunity to speculate on PTLA. We certainly will know more
after PTLA meets with the FDA but I bet it will be positive to move the stock
up from the current depressing level.
As I said, I used a combo option setup to hedge my
risk and it really works well as today’s 20% plunge did not hurt me at all. I
will use this opportunity to go long again for PTLA as I think we now have a
better chance to win this time. Actually
today’s price action for PTLA is quite impressive and positive, suggesting the
selling pressure may continue to go down from here, barring of course any unknown negative
surprises emerge.
