    Cost-effectiveness of HLA-DQB1/HLA-B pharmacogenetic-guided treatment and blood monitoring in US patients taking clozapine.
    Pharmacogenomics J 2018 Jan 3. Epub 2018 Jan 3.
    Division of Nephrology, University Hospitals of Geneva and University of Geneva, Geneva, Switzerland.
    Less than 1% of adult patients with schizophrenia taking clozapine develop agranulocytosis, and most of these cases occur within the first weeks of treatment. The human leukocyte antigen (HLA) region has been associated with genetic susceptibility to clozapine-induced agranulocytosis (single amino acid changes in HLA-DQB1 (126Q) and HLA-B (158T)). The current study aimed to evaluate the cost-effectiveness, from a healthcare provider's perspective, of an HLA genotype-guided approach in patients with treatment-resistant schizophrenia who were taking clozapine and to compare the results with the current absolute neutrophil count monitoring (ANCM) schemes used in the USA.

    Zhonghua Zhong Liu Za Zhi 2017 Nov;39(11):868-878
    Neutropenia is the most common hematologic toxicity of myelosuppressive chemotherapy and radiotherapy. The degree and duration of neutropenia are directly related to the risk of infection and even death, which can also affect the relative dose intensity of chemotherapy and the prognosis of patients. At present, clinicians tend to underestimate the harm of neutropenia, and are in lack of knowledge on granulocyte colony-stimulating factor(G-CSF), especially on prevention and treatment of neutropenia.

    Background: We investigated selumetinib (AZD6244, ARRY-142886), an oral, potent, and highly selective, allosteric MEK1/2 inhibitor, plus platinum-doublet chemotherapy for patients with advanced/metastatic non-small cell lung cancer.

    Methods: In this Phase I, open-label study (NCT01809210), treatment-naïve patients received selumetinib (50, 75, 100 mg BID PO) plus standard doses of gemcitabine or pemetrexed plus cisplatin or carboplatin. Primary objectives were safety, tolerability, and determination of recommended Phase II doses. Read More

    Correlation Between Serum Concentrations of N-Desmethylclozapine and Granulocyte Levels in Patients with Schizophrenia: A Retrospective Observational Study.

    Background: Clozapine is restricted to use in patients with treatment-refractory schizophrenia due to the risk of a serious drop in absolute neutrophil granulocyte count (ANC). The formation of reactive, unstable metabolites (adducts) has been suggested as a mechanism of clozapine-induced granulocyte decline. These adducts are not detectable in vivo, but stable clozapine metabolites could potentially be indirect pharmacokinetic measures of adduct formation. Read More
