Evaluation of cytogenetic and molecular markers with MTX-mediated toxicity in pediatric acute lymphoblastic leukemia patients
ConclusionSLC19A1 facilitates the import of cyclic dinucleotides and reduced folates, evaluating genotypes in this gene can help in better management of patients on methotrexate treatment. Assessing a broader gene panel can help in finding more associated markers and delivering personalized medicine to the patients. (Source: Cancer Chemotherapy and Pharmacology)

Cytotoxic mechanisms of doxorubicin at clinically relevant concentrations in breast cancer cells
AbstractDoxorubicin (DOX) is a chemotherapeutic agent frequently used for the treatment of a variety of tumor types, such as breast cancer. Despite the long history of DOX, the mechanistic details of its cytotoxic action remain controversial. Rather than one key mechanism of cytotoxic action, DOX is characterized by multiple mechanisms, such as (1) DNA intercalation and adduct formation, (2) topoisomerase II (TopII) poisoning, (3) the generation of free radicals and oxidative stress, and (4) membrane damage through altered sphingolipid metabolism. Many past reviews of DOX cytotoxicity are based on supraclinical concentrati...

Prediction of drug –drug interaction potential mediated by transporters between dasatinib and metformin, pravastatin, and rosuvastatin using physiologically based pharmacokinetic modeling
ConclusionsThis PBPK model accurately described the observed PK profiles of dasatinib. The validated PBPK model predicts low risk of clinically significant DDIs between dasatinib and metformin, pravastatin, or rosuvastatin. (Source: Cancer Chemotherapy and Pharmacology)

Adaptive dosing of sunitinib in a metastatic renal cell carcinoma patient: when in silico modeling helps to go quicker to the point
Conclusions and discussionThis case suggests that model-based adaptive dosing could have allowed to reach quicker the best dosing with Sunitinib, thus possibly ensuring a better management of this patient. Model-informed dosing should be used instead of empirical search for the most appropriate dosing to ensure a good benefit/risk ratio with Sunitinib, especially in the context of such aggressive disease.

A phase I study of AZD2171 and Temsirolimus in patients with advanced gynecological malignancies
ConclusionsDespite a conservative dose escalation, the toxicity data demonstrated that the combination of AZD2171 and Temsirolimus was not tolerable. Increased awareness of novel toxicities, pharmacological interactions, coupled with strict patient selection and early mitigation of side effects may enhance phase I clinical trial development.

Pharmacokinetics and pharmacodynamics of MEDI0680, a fully human anti-PD-1 monoclonal antibody, in patients with advanced malignancies
AbstractMEDI0680 is a humanized immunoglobulin monoclonal antibody that targets human programmed cell death protein 1 (PD-1) for the treatment of cancer. A population two-compartmental pharmacokinetic (PK) model and a sequential direct maximal effective drug concentration receptor occupancy (RO) model with baseline parameters were developed to quantify PK variability, identify significant covariates, and characterize the relationship between the PK and the RO of MEDI0680. A total of 58 patients with advanced malignancies received MEDI0680 by intravenous infusion at a dose of 0.1 –20 mg/kg in a phase 1 study. The clearan...

The effects of pazopanib on doxorubicin pharmacokinetics in children and adults with non-rhabdomyosarcoma soft tissue sarcoma: a report from Children ’s Oncology Group and NRG Oncology study ARST1321
ConclusionThe PK data of seven patients treated on ARST1321 is consistent with previously reported population and post hoc doxorubicin clearance and doxorubicinol apparent clearance estimates, showing that the addition of pazopanib does not significantly alter doxorubicin pharmacokinetics. These data support the safety of administration of pazopanib with doxorubicin-containing chemotherapy. (Source: Cancer Chemotherapy and Pharmacology)

Correlation between pharmacokinetic parameters of 5-fluorouracil and related metabolites and adverse reactions in East-Asian patients with advanced colorectal cancer
ConclusionsThere are obvious individual differences in AUC values in CRC patients receiving different dosages of 5-FU based on BSA. The ideal AUC range of 5-FU is 18.23 –29.17 mg·h/L. There was a significant correlation between 5-FUH2 and FABL plasma concentration and adverse reactions. (Source: Cancer Chemotherapy and Pharmacology)
