Varubi (rolapitant) approved to prevent delayed phase chemotherapy-induced nausea and vomiting

The U.S. Food and Drug Administration approved Varubi (rolapitant) to prevent delayed phase chemotherapy-induced nausea and vomiting (emesis). Varubi is approved in adults in combination with other drugs (antiemetic agents) that prevent nausea and vomiting associated with initial and repeat courses of vomit-inducing (emetogenic and highly emetogenic) cancer chemotherapy.

GeneSight test better predicts antidepressant outcomes for patients with depression

The combinatorial, multi-gene GeneSight test has been found to better predict antidepressant treatment outcomes for patients with depression, and their use of health care resources, than any of the individual genes that comprise the test, according to a peer-reviewed analysis by investigators from the Mayo Clinic and Assurex Health, and published online by The Pharmacogenomics Journal.

Z-endoxifen may provide better treatment for women with estrogen positive breast cancer

A Phase I trial of endoxifen, an active metabolite of the cancer drug tamoxifen, indicates that the experimental drug is safe, with early evidence for anti-tumor activity, a Mayo Clinic study has found. The findings indicate that Z-endoxifen, co-developed by Mayo Clinic Cancer Center and the National Cancer Institute, may provide a new and better treatment for some women with estrogen positive breast cancer and, in particular, for those women who do not respond to tamoxifen and aromatase inhibitors.

Genetics and cardiovascular drugs: an interview with Nancy Lurker, CEO of PDI and Paul Kinnon, CEO of Transgenomic, Inc.

People inherit different versions of any particular gene, and some genes affect how patients process and metabolize medicines. This especially holds true for people with cardiovascular (CV) disease. They may be fast, slow or non-metabolizers and might also react badly (with serious adverse events) to certain drug therapies or not at all.

Genetic discovery could take guesswork out of prescribing correct dose of drugs

The discovery of genetic differences affecting up to a third of the population could take the guesswork out of prescribing the correct dose of 25 percent of drugs currently on the market, researchers say.

Long winter months impact tamoxifen treatment for breast cancer

For women diagnosed with a form of breast cancer known as estrogen receptor positive (ER+) breast cancer, tamoxifen is an essential drug used in the treatment and prevention of recurring breast cancer.

Possible connection between mitochondrial CYP2D6 and Parkinson's

With a new insight into a model of Parkinson's disease, researchers from the University of Pennsylvania School of Veterinary Medicine have identified a novel target for mitigating some of the disease's toll on the brain.

Genetic differences in enzyme CYP2D6 play a key role in effectiveness of tamoxifen for breast cancer

For nearly a decade, breast cancer researchers studying the hormone therapy tamoxifen have been divided as to whether genetic differences in a liver enzyme affect the drug's effectiveness and the likelihood breast cancer will recur.

Rapid test to identify patients not responding to painkiller tramadol

French researchers have found a way to identify quickly the 5-10% of patients in whom the commonly used painkiller, tramadol, does not work effectively. A simple blood test can produce a result within a few hours, enabling doctors to switch a non-responding patient on to another painkiller, such as morphine, which will be able to work in these patients.

Breast cancer patients taking tamoxifen anxious to have CYP2D6 genetic test

While the medical community continues to debate the benefits of CYP2D6 genetic testing for women on the breast cancer treatment tamoxifen, patients using the medication are anxious to have the tests. According to a new survey of more than 700 women with breast cancer currently taking tamoxifen, almost 80 percent of respondents would choose to have a genetic test that determines CYP2D6 genotype, yet only 14 percent of these women have been tested. CYP2D6 is an enzyme that influences how well the body processes tamoxifen into its more active form.

Cough suppressant syrup may predict patients metabolise tamoxifen in breast cancer treatment

Cough medicine could be used as way of predicting how well individual patients metabolise tamoxifen used in the treatment of their breast cancer, according to new research presented at the 22nd EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics in Berlin today

New pharmacogenetic test enables a personalized medicine approach

Luminex Corporation, today announced that it has commercially launched its first pharmacogenetic test, the xTAG CYP2D6 Kit, which recently received 510(k) clearance from the U.S. Food and Drug Administration (FDA).

Changing drug therapy can help breast cancer patients get full benefit of Tamoxifen

Recently published research has shown that some breast cancer patients taking tamoxifen may not be getting the full benefit of their treatment because they have also been taking selective serotonin reuptake inhibitors (SSRIs), prescribed drugs that inhibit the effect of an important enzyme. Now researchers have developed a strategy for overcoming this problem, the seventh European Breast Cancer Conference (EBCC7) in Barcelona will hear today (Wednesday).

PAREXEL genotypes over 10,000 potential study participants to identify 400 CYP2D6 poor metabolizers

PAREXEL International Corporation, a leading global biopharmaceutical services provider, today announced that it has completed a large and complex pharmacogenetics-based early phase study. The study was conducted in a healthy volunteer population of poor metabolizers of Cytochrome P450 2D6 (CYP2D6), an important enzyme involved in the metabolism of drugs. The study monitored the QTc interval following administration of a neurological treatment, which has been shown to have a higher drug exposure in poor metabolizers of CYP2D6.

Presentation of results from open-label extension study of Xenazine

Lundbeck Inc. today announced the presentation of results from an open-label extension study of Xenazine- (tetrabenazine) for the treatment of chorea associated with Huntington's disease (HD). Data from this study demonstrated that after an 80-week treatment period, subjects treated with Xenazine experienced a statistically significant reduction in chorea score (p< 0.0001) as measured using the Unified Huntington's Disease Rating Scale (UHDRS) compared with baseline.
