Xiaflex denial letter for a second round of shots, anyone else get denied?

[norcal1970]

My Dr. attempted to get three more rounds of xiaflex (6 shots) after my first four rounds (8 shots).   Apparently the FDA only approves 8 shots per chunk of plaque.  My plaque has shrank about 40-50% and my upwards curve went from 70 -50 degrees.  The fourth round of shots is where I got the most curvature improvement and shrinkage of the plaque.   Sadly I am stuck with a 50% curve.  I plan to appeal but I don't expect any success.  

According to the FDA you can only get 8 shots per chunk of plaque.  Any additional rounds must be applied to a new chunk of plaque.  See attached letter.

Has anyone else got denied like this?  Your feedback is greatly appreciated.  The battle continues.  Bought a Soma vacuum device today and I already have a Restorex.

Thanks
