University of Missouri researchers believe they have found exactly how Kalydeco (Vx-770), the first drug of its kind to treat the underlying cause of cystic fibrosis, works and how to improve its effectiveness in the future.
A team led by Sean Ekins at Collaborative Drug Discovery in Burlingame, Cal., and Joel Freundlich at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School has trained computers to sift through drug libraries and pick out compounds likely to clobber TB with minimal side effects to humans. They have ‘taught’ the computers to understand which chemical features of a drug are associated with efficacy against TB and which are associated with toxicity to mammalian cells. The process may lead to much less trial and error in finding new therapies. The computers even rediscovered a compound reported 40 years ago to have anti-TB activity but since forgotten.
St. Jude Children’s Research Hospital plays key role in research showing that drug shortages erode the quality and increase the cost of cancer care; experts warn that shortages persist despite efforts to fix the problem.
The Hematology/Oncology Pharmacy Association (HOPA) has released a survey of oncology pharmacists which warns that oncology drug shortages happen often and have serious negative consequences on cancer patients in the in the United States. Published in the April 1, 2013 issue of the American Journal of Health-System Pharmacy, the survey was completed by hematology/oncology pharmacists, who care for cancer patients in all phases of treatment and are uniquely positioned to provide insight on oncology drug shortages.
Researchers at Moffitt Cancer Center have completed a phase II clinical trial to determine the safety and efficacy of dasatinib for patients with higher-risk myelodysplastic syndromes (MDS), chronic myelomonocytic leukemia, or acute myeloid leukemia resulting from MDS and have failed treatment with azanucleosides. The therapy may not be effective for all patients, but those with trisomy 8 chromosomal disorder have higher rates of stable disease and respond better to treatment with dasatinib, the study shows.

The American Academy of Neurology (AAN), the world’s largest professional association of neurologists, is releasing a position paper on how the practice of prescribing drugs to boost cognitive function, or memory and thinking abilities, in healthy children and teens is misguided. The statement is published in the March 13, 2013, online issue of Neurology, the medical journal of the American Academy of Neurology.
The heart failure drug digoxin, used less and less since it “failed” in its 1997 clinical trial, may do something no drug has achieved since: reduce by 34 percent the chances that heart failure patients will be admitted to the hospital within 30 days of first taking it.

A commonly used erectile dysfunction drug, sildenafil, doesn’t help patients who have heart failure with preserved ejection fraction, a condition in which the heart’s lower chambers are stiff and cannot relax and fill fully between beats. That is the finding of the RELAX study, presented today at the American College of Cardiology’s 62nd Annual Scientific Session and simultaneously published in The Journal of the American Medical Association. The study’s lead author called the results disappointing.

A single dose of an investigational anti-inflammatory drug called inclacumab considerably reduces damage to heart muscle during angioplasty (the opening of a blocked artery), according to a recent international clinical trial spearheaded by Dr. Jean-Claude Tardif, Director of the Research Centre at the Montreal Heart Institute, affiliated with the University of Montreal.
Researchers in the University of Delaware's Department of Biological Sciences are investigating a new drug that has shown positive results in early tests of its ability to fight a rare and aggressive form of breast cancer.
The pharmaceutical industry has pulled back on marketing to physicians and consumers, yet some enduring patterns persist. According to a new study, advertising peaked in 2004, with industry promotion to physicians declining nearly 25 percent by 2010, to $27.7 billion or 9 percent of sales. Similar declines were seen in direct-to-consumer advertising, which remains concentrated among a small number of products.

The drug bevacizumab, also known by the trade name Avastin, shrinks tumors briefly in patients with an aggressive brain cancer known as glioblastoma multiforme, but then they often grow again and spread throughout the brain for reasons no one previously has understood. Now, Mayo Clinic researchers have found out why this happens.

Researchers have identified a pivotal protein in a cellular transformation that makes a cancer cell more resistant to treatment and more capable of growing and spreading, making it an inviting new target for drug development.
Cancer drugs should kill tumors, not encourage their spread. But new evidence suggests that an otherwise promising class of drugs may actually increase the risk of tumors spreading to bone, according to researchers at Washington University School of Medicine in St. Louis.
Patients with advanced, recurrent, or persistent cervical cancer that was not curable with standard treatment who received the drug bevacizumab (Avastin) lived 3.7 months longer than patients who did not receive the drug, according to an interim analysis of a large, randomized clinical trial.
Findings from clinical trial patients with metastatic renal cell carcinoma, a common kidney cancer, show they did not have accelerated tumor growth after treatment with sunitinib, in contrast to some study results in animals.
