General information 

Novartis may have the most new drug approvals, but Roche, Lilly and AbbVie's launches win on value

In the last five years, the world’s top 11 drugmakers have brought 76 new meds to market, Evaluate Vantage said in a recent report. Novartis sits pretty in the No. 1 spot with a dozen green lights to its name, including those for gene therapy Zolgensma and the first-ever approved CAR T-cell therapy, Kymriah. Bristol Myers Squibb rounds out last place with just three—and all of them courtesy of its $74 billion Celgene buyout. (Read more)


Biden’s competition order directs FDA on biosimilars, importation and OTC hearing aids

“Just a handful of companies control the market for many vital medicines, giving them leverage over everyone else to charge whatever they want. As a result, Americans pay two and a half times more for prescription drugs than in any other leading country. And nearly one in four Americans struggles to afford their medication,” Biden said. 

One such policy includes revisiting prescription drug importation from Canada, where prices are cheaper than in the US, by instructing the FDA Commissioner to work with states and tribes that propose to develop section 804 importation programs. (Read more)

Novartis sued multiple Gx filers (total 17!!) alleging infringement of US 8,101,659; US 8,796,331; US 8,877,938; and US 9,388,134. This was a claim construction litigation. 

There are three issues for the Court to decide with respect to the "trisodium [sacubitril-valsartan] hemipentahydrate" and "in crystalline form" limitations: 

1. Is "trisodium [sacubitril-valsartan] hemipentahydrate" by itself limited to crystalline form?

2. Are the claim terms "trisodium [sacubitril-valsartan] hemipentahydrate" and "crystalline form" limited to "a... supramolecular complex having formula units ..., wherein each formula unit in a unit cell... has 2.5 water molecules and 3 sodium ions"? and

3. Are the '134 Patent claims limited to "substantially pure" trisodium [sacubitril-valsartan] hemipentahydrate?
