This is the description from the same author on 04/09
"Amended NDA for Imagify (Perflubutane Polymer Microspheres) for Injectable Suspension as a cardiac imaging agent for the detection of coronary artery disease. Amended indication would be limited to subsets of patients undergoing pharmacologic stress techniques compared to original request for more widespread use with an expected PDUFA decision date of 5/31/09."
So the 5/31 is for the original claim. I am not sure if the amended request still shares the deadline and the request was submitted before the CRL was received.
On the other hand, per google discussion borad, this author now believes that the amended the request is off the table because of the wording used in the latest PR regarding the design of the clinical trial for the purpose of the original claim. Ironically, if that's the case 5/31 is the deadline for that claim.
So this guy gives at least 3 different estimate:
4/9: He mentioned amended claim for narrower use and still list 5/31 as the deadline for PDUFA decision--and a date to play with
5/19: Based on the exact same information, he claimed the decision date was pending because of the amended claim
5/20: He believes the amended claim is off the table without any substantial proof, however if true, 5/31 is still the deadline but possibly will be delayed into Q3
As I replied in another thread, giving the going concern of ACUS, it's hard for them to survive beyond Q3, and such a trial could be costly (this is the reason why a narrower claim was submitted in the first place), I guess there might be some compromise or partnership to either get the narrower claim proved or going forward to achieve the broad claim.
Lastly, in the author's 5/19 article he did mention that "The goal of the amended NDA and narrower claim for Imagify is to improve the risk/benefit ratio for the cardiac imaging agent by limiting its use to patients undergoing pharmacologic stress tests so that additional clinical studies are not required as outlined in the CRL from the FDA" |
