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.

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.

ReviewTriggering receptor expressed on myeloid cells receptor family modulators: a patent review.
Triggering receptor expressed on myeloid cells (TREM) receptors and TREM-like transcript (TLT; or TREML) receptors of the immunoglobulin superfamily are known as key modulators of host immune responses. TREM-1 (CD354) and TREM-2 share the transmembrane adaptor DNAX-activation protein of 12 kDa (DAP12), but they possess separate stimulatory and inhibitory functional roles, especially in myeloid cells. ⋯ So far, therapeutic use of activators/blockers specific for TREMs and TLTs has been limited to preclinical animal models. TREM-1 is an immediate therapeutic target for acute and chronic inflammatory conditions, especially sepsis. Certain mutations in DAP12 and TREM-2 manifest into a disorder named polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy, and newly identified TREM-2 variants confer a significant increase in risk of developing Alzheimer's disease. This makes TREM-2 an attractive therapeutic target for neurodegenerative diseases.

EditorialBiosimilars lining up to compete with Herceptin--opportunity knocks.
Trastuzumab is a monoclonal antibody developed by Genentech as a treatment for breast cancer and gastric cancer when the cancer cells overexpress HER2, a membrane-bound receptor activated by epidermal growth factor. Now marketed by Roche under the trade name Herceptin, trastuzumab has been readily adopted as treatment for some of the most invasive types of breast cancer. ⋯ As biosimilar manufacturers look for opportunities to market biosimilar trastuzumab products, Roche has positioned itself to protect its market by developing additional anti-HER2 products complementary to Herceptin. The advent of competition from biosimilars should bring some opportunity for cost savings for patients, as well as incentive for continued advancement in development of better treatments to fight breast cancer.

For over 20 years, the US Patent & Trademark Office (USPTO) has been granting patents to DNA sequences. But on 13 June 2013, the US Supreme Court decided that genomic DNA sequences are unpatentable because they are products of nature. This article discusses the effect that this will have on DNA patents in the Unites States and in other countries.
