EditorialTeva Pharmaceuticals v. Sandoz: availability of generic glatiramer acetate and the impact to patent litigation claim construction.
In the upcoming case of Teva Pharmaceuticals v. Sandoz, the U. ⋯ Supreme Court will address how much deference the appellate court should afford to a trial court's claim construction ruling. The effect of this decision will be far-reaching, as how claims are construed can determine whether a patent is infringed or not infringed, valid or invalid.

ReviewCyclodextrins: improving the therapeutic response of analgesic drugs: a patent review.
Cyclodextrins (CDs) are cyclic oligosaccharides that have recently been recognized as useful tools for optimizing the delivery of such problematic drugs. CDs can be found in at least 35 pharmaceutical products, such as anticancer agents, analgesic and anti-inflammatory drugs. Besides, several studies have demonstrated that CD-complexed drugs could provide benefits in solubility, stability and also improve pharmacological response when compared with the drug alone. ⋯ We noticed that some patents are related to the complexation of opioids, NSAIDs, as well as natural products, in different types of CDs. The use of CDs creates the prospect of developing new therapeutic options for the most effective treatment of painful conditions, allowing a reduction of dosage of analgesic drugs and the occurrence of side effects. Thus, CDs can be an important tool to improve the efficacy and pharmacological profile of analgesic drugs.

ReviewF508del-cystic fibrosis transmembrane regulator correctors for treatment of cystic fibrosis: a patent review.
Cystic fibrosis (CF) is an autosomal recessive genetic disease caused by malfunction of CF transmembrane regulator (CFTR). The deletion of a phenylalanine at residue 508 (F508del) is the most common mutation that causes cellular processing, chloride channel gating and protein stability defects in CFTR. Pharmacological modulators of F508del-CFTR, aimed at correcting the cellular processing defect (correctors) and the gating defect (potentiators) in CFTR protein, are regarded as promising therapeutic agents for CF disease. Endeavors in searching F508del-CFTR modulators have shown encouraging results, with several small-molecule compounds having entered clinical trials or even represented clinical options. ⋯ Cyclopropane carboxamide derivatives of CFTR correctors continue to dominate in this area, among which lumacaftor (a NBD1-MSD1/2 interface stabilizer) is the most promising compound and is now under the priority review by US FDA. However, the abrogation effect of ivacaftor (potentiator) on lumacaftor suggests the requirement of discovering new correctors and potentiators that can cooperate well. Integration screening for simultaneously identifying combinations of correctors (particularly NBD1 stabilizer) and potentiators should provide an alternative strategy. A recently reported natural product fraction library may be useful for the integration screening.
