The personal information sphere: An integral approach to privacy and related information and communication rights

Data protection laws, including the European Union General Data Protection Regulation, regulate aspects of online personalization. However, the data protection lens is too narrow to analyze personalization. To define conditions for personalization, we should understand data protection in its larger fundamental rights context, starting with the closely connected right to privacy. If the right to privacy is considered along with other European fundamental rights that protect information and communication flows, namely, communications confidentiality; the right to receive information; and freedom of expression, opinion, and thought, these rights are observed to enable what I call a “personal information sphere” for each person. This notion highlights how privacy interferences affect other fundamental rights. The personal information sphere is grounded in European case law and is thus not just an academic affair. The essence of the personal information sphere is control, yet with a different meaning than mere control as guaranteed by data protection law. The personal information sphere is about people controlling how they situate themselves in information and communication networks. It follows that, to respect privacy and related rights, online personalization providers should actively involve users in the personalization process and enable them to use personalization for personal goals

Moving molecular targeted drug therapy towards personalized medicine: Issues related to clinical trial design

With the event of new Molecular targets, clinical trial design requirements to perform these trials are changing. This paper discusses some of the considerations that need to be taken into account when designing a trial, including those trials that assess combinations of targets

Omineca Herald, May, 23, 1924

Background: LKB1 mutations are the underlying genetic abnormality causing Peutz-Jeghers syndrome (PJS) and are a potential target for everolimus. In this phase II study, the efficacy of everolimus on polyp and tumor growth in PJS patients was investigated. Methods: Adult patients with a proven LKB1 mutation and who were suitable for everolimus treatment were included in two different PJS cohorts: (a) patients with unresectable malignancies and (b) patients with high-risk polyps. Treatment in both groups was oral everolimus, 10 mg daily. Response rates were primary endpoints for both cohorts. Results: Between October 2011 and April 2016, only two patients were enrolled, one in each cohort. A 49-year-old patient with advanced pancreatic cancer in cohort 1 was progressive after 2 months. A 52-year-old male patient in cohort 2 experienced severe toxicity and refused treatment after 4 months, even though endoscopy suggested stabilization of polyps. Adverse

Pharmacogenetics of telatinib, a VEGFR-2 and VEGFR-3 tyrosine kinase inhibitor, used in patients with solid tumors

Purpose Telatinib is an orally active small-molecule tyrosine kinase inhibitor of kinase insert domain receptor (KDR; VEGFR-2) and fms-related tyrosine kinase 4 (FLT4; VEGFR-3). This study aims at the identification of relationships between single nucleotide polymorphisms (SNPs) in genes encoding for transporter proteins and pharmacokinetic parameters in order to clarify the significant interpatient variability in drug exposure. In addition, the potential relationship between target receptor polymorphisms and toxicity of telatinib is explored. Methods Blood samples from 33 patients enrolled in a phase I dose-escalation study of telatinib were analyzed. For correlation with dose normalized AUC(0–12), ATP-binding cassette (ABC) B1 (ABCB1), ABCC1, and ABCG2 were the genes selected. For correlation with telatinib toxicity, selected genes were the drug target genes KDR and FLT4. Results No association between dose normalized AUC(0–12) and drug transporter protein polymorphisms was observed. In addition, no association between toxicity and KDR or FLT4 genotype or haplotype was seen. Conclusions Our pharmacogenetic analysis could not reveal a correlation between relevant gene polymorphisms and clinical and pharmacokinetic observations of telatinib

Influence of OATP1B1 Function on the Disposition of Sorafenib-β-D-Glucuronide

The oral multikinase inhibitor sorafenib undergoes extensive UGT1A9-mediated formation of sorafenib-β-D-glucuronide (SG). Using transporter-deficient mouse models, it was previously established that SG can be extruded into bile by ABCC2 or follow a liver-to-blood shuttling loop via ABCC3-mediated efflux into the systemic circulation, and subsequent uptake in neighboring hepatocytes by OATP1B-type transporters. Here we evaluated the possibility that this unusual process, called hepatocyte hopping, is also operational in humans and can be modulated through pharmacological inhibition. We found that SG transport by OATP1B1 or murine Oatp1b2 was effectively inhibited by rifampin, and that this agent can significantly increase plasma levels of SG in wildtype mice, but not in Oatp1b2-deficient animals. In human subjects receiving sorafenib, rifampin acutely increased the systemic exposure to SG. Our study emphasizes the need to consider hepatic handling of xenobiotic glucuronides in the design of drug-drug interaction studies of agents that undergo extensive phase II conjugation
