The FDA is taking new steps to better ensure the quality of compounded drugs, while also preserving patient access to these medications,Pharmacy Timesreported. In a statement, FDA Commissioner Scott Gottlieb said that the agency’s compounding program, which includes implementation and provisions of the law, is a priority.

In a revised draft memorandum of understanding, the FDA is making changes to its2018 Compounding Policy Priorities Plan. The memorandum addresses investigations of complaints related to compounded drug products distributed outside the state, distribution of inordinate amounts of compounded drug products interstate, and submission and disclosure of information.

Patients with asthma with certain genotype combinations demonstrate more intense symptoms when combined with close proximity to roadways, suggesting that traffic-related air pollution exposure may affect the likelihood of asthma diagnosis and exacerbations,Contemporary Clinicreported.The study, the results of which were published inScientific Reports,considered individual data on genotype, residential address, asthma diagnosis, and exacerbations from the Environmental Polymorphisms Registry.

Patients were divided into 3 groups—hyper-responders, hypo-responders, and neither—and they measured the participants' distance between their residence and nearest major road. Patients with certain genetic profiles had exhibited more intense symptoms following exposure to traffic pollution. Furthermore, patients with asthma who lacked this genetic profile did not have the same sensitivity to traffic pollution and do not experience worse asthma symptoms.

FDA officials recently granted breakthrough therapy designation for tezepelumab in patients with severe asthma without an eosinophilic phenotype,Specialty Pharmacy Timesreported. Tezepelumab is a potential first-in-class drug that blocks thymic stromal lymphopoietin or TSLP, an upstream modulator of multiple inflammatory pathways, according to Amgen.

Blocking TSLP may prevent the release of pro-inflammatory cytokines by immune cells, resulting in the prevention of asthma exacerbations and improved asthma control, Amgen and AstraZeneca said in a statement. The designation is based on data from the phase 2b PATHWAY trial, which showed a significant reduction in the annual asthma exacerbation rate compared with a placebo over a 52-week treatment period.

Pharmacists may get more questions about Ibrance if their patients have seen a new commercial for the prescription to treat breast cancer. In the spot, called “Carla,” it is an ordinary week for her, which makes it special. Even though Carla has metastatic breast cancer, she can still travel to a lakeside cabin with her family. She spends her time picking lavender, playing games, and enjoying her new normal. According to the commercial, Ibrance has been shown to be more effective at delaying her disease than letrozole.
