Hetero, Cipla and Aurobindo are the only 3 IN DMFs active. This import is from Ireland, Is Hetero planning to import intermediates from Novartis Ireland? Or this is some critical impurity issue? Investigation could be interesting.

GSK vs Teva on Skinny label or Carve-out issues 

Section viii carve-outs

What is Section viii carve-outs in US? 

The statute (21 U.S.C. § 355(j)(2)(A)(viii)) allows the generic sponsor to remove or “carve-out” the protected indication or other protected condition of use from the product labelling and submit a “section viii” statement explaining that the applicant does not seek approval for the protected use. 

Though statute looks simple, the issues related to section viii carve-outs remain unresolved in the context of the small molecules. In February 2020, the FDA issued draft guidance which makes it explicitly clear that carve-outs are indeed permissible for biosimilars.

This is the case of Carvedilol and GSK’s patent reissued in 2008, related to treatment of congestive heart failure using Carvedilol.

In the lower court, Teva argued that it could not be found to have induce infringement because the patented use was carved out on the skinny label. The lower Court held that GSK failed to prove Teva caused the direct infringement. 

GSK appealed. On appeal, GSK argued that Teva promotes its generic product as being the same as the branded product. 

In October, a three-judge CAFC panel decided in favour of GSK.  

Now, the appeals court will review the case "en banc," which means the court's entire complement of 12 judges will hear arguments. 

This will be an interesting case to follow and it would show path for generics to carve out labels and subsequent marketing of their products. News here.
