Ariad's Ponatinib Runs Into Big Trouble

Email This Entry

Posted by Derek

Just a note, in case any investors didn't realize it: no, drugs (and a drug companies) are not out of the woods after a compound has been approved and is on the market. Take a look at what's happening to Ariad and their BCR-ABL compound Iclusig (ponatinib). This is used to treat patients that have become resistant to Gleevec, and it's a very big deal for both those patients and for Ariad as a company.

But the percentage of patients on the drug showing serious complications from blood clots has been rising, and that's prompted a number of moves: enrollment in further clinical trials is on hold, dosages are being lowered for current patients, and the product's label is being changed to add warnings of cardiovascular effects. If you're wondering how this affects Ariad as a whole, well, the stock is down 66% in premarket trading as I write. . .

@2: The HR guys at Ariad are idiots, so they've probably lost your applicafion anyway.

@ #1

That's interesting. The President of Global R&D at Jiangsu Hengrui Medicine is a former Lilly employee.

After the publication of a case report of dramatic response to Gleevec in a patient with Pulmonary hypertension, a colleague and I prescribed it off label for two patients (one pt by each of us) with advanced Pulmonary hypertension. Both patients developed severe neutropenia with just 200mg (half the starting dose for CML). So abelson kinase is not something to mess around with. In patients with CML, the mutant stem cell clone is hyper active and it is fine to inhibit it. May be more potent inhibitors can have multiple effects since abelson kinase interacts with an obscene number of other signalling proteins.

#4, It is correct!
One of two, Dr. Cao already listed himself as VP of HengRui in Linkedin, while also working at Lilly (also listed in Linkedin)?? What a stupidity!!

It's a real shame for Hengrui's R&D head/President, Dr. Zhang, also former Lilly's.. He's toasted apparently.
