MNTA/TEVA FWIW: I sent an email to TEVA's IR last week asking if TEVA's generic had been developed in-house. Here was the response verbatim from TEVA's IR which I was pretty shocked he answered so frankly:
"It is well-known [I sure as heck didn't know this] that we have partnered with another company regarding the product. I am not sure I understand why that would be consequential."
In his follow up email he stated "We are very pleased with our partner for generic Lovenox."
I then asked who the partner was, but as expected he said that was confidential.
So there you have it straight from the horses mouth. TEVA's generic lovenox is indeed from a 3rd party.
