[Securing the patient's care path receiving oral anticancer therapy: Experimentation around a pharmaceutical hospital-to-community liaison].

Due to the increasing prescription of oral anticancer therapies, the inpatient care pathway has shifted to an outpatient care pathway. This transformation requires an interdisciplinary coordination to provide a continuum of care and ensure therapeutic monitoring, as well as patient safety. To better support patients on oral anticancer therapies, a task group named "hospital-to-community pharmacist coordination" has been set up to create tools aiming at standardising the information exchanged between ambulatory and hospital pharmacists.

FDA- and EMA-Approved Tyrosine Kinase Inhibitors in Advanced -Mutated Non-Small Cell Lung Cancer: Safety, Tolerability, Plasma Concentration Monitoring, and Management.

Non-small-cell lung cancer (NSCLC) is the most common form of primary lung cancer. The discovery of several oncogenic driver mutations in patients with NSCLC has allowed the development of personalized treatments based on these specific molecular alterations, in particular in the tyrosine kinase (TK) domain of the epidermal growth factor receptor ( gene. Gefitinib, erlotinib, afatinib, and osimertinib are TK inhibitors (TKIs) that specifically target and are currently approved by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) as first line treatment for sensitive -mutant patients.

Patients And Methods: In this two-step phase I trial, seventeen and eleven patients were enrolled in the XELIRI and XELIRINOX stages, respectively.

Results: In XELIRI, a total of 136 chemotherapy cycles were administered with a median number of 8 cycles per patient (2-16).

Guidelines for the practical stability studies of anticancer drugs: a European consensus conference.

Stability studies performed by the pharmaceutical industry are only designed to fulfill licensing requirements. Thus, post-dilution or -reconstitution stability data are frequently limited to 24h only for bacteriological reasons regardless of the true chemical stability which could, in many cases, be longer. In practice, the pharmacy-based centralized preparation may require infusions to be made several days in advance to provide, for example, the filling of ambulatory devices for continuous infusions or batch preparations for dose banding.

Intraperitoneal administration of novel doxorubicin loaded polymeric delivery systems against peritoneal carcinomatosis: experimental study in a murine model of ovarian cancer.

Objective: Peritoneal spread is an adverse outcome in ovarian cancer. Despite clinical efficiency, intraperitoneal (i.p.

Factors for hematopoietic toxicity of carboplatin: refining the targeting of carboplatin systemic exposure.

Purpose: Area under the curve (AUC) dosing is routinely carried out for carboplatin, but the chosen target AUC values remain largely empirical. This multicenter pharmacokinetic-pharmacodynamic (PK-PD) study was performed to determine the covariates involved in the interindividual variability of carboplatin hematotoxicity that should be considered when choosing individual target AUCs.

Patients And Methods: Three hundred eighty-three patients received carboplatin as part of established regimens.

Metabolism and pharmacokinetics of EAPB0203 and EAPB0503, two imidazoquinoxaline compounds previously shown to have antitumoral activity on melanoma and T-lymphomas.

For several years, our group has been developing quinoxalinic compounds. Two of them, N-methyl-1-(2-phenethyl)imidazo[1,2-a]quinoxalin-4-amine (EAPB0203) and 1-(3-methoxyphenyl)-N-methylimidazo[1,2-a]quinoxalin-4-amine (EAPB0503), have emerged as the most promising anticancer drugs. In the present work, we determined metabolism pathways using liver microsomes from four mammalian species including human.

Involvement of gene polymorphisms of the folate pathway enzymes in gene expression and anticancer drug sensitivity using the NCI-60 panel as a model.

Folate, a vitamin of the B group involved in one-carbon group metabolism, plays an important role in DNA synthesis and methylation. Several polymorphisms in the genes involved in folate uptake and biotransformations have been shown to be associated to the risk of cancer and to anticancer drug response. We studied common polymorphisms in MTHFR (N(5,10)-methylene-tetrahydrofolate reductase), MTHFD1 (N(5,10)-methylene-tetrahydrofolate dehydrogenase), MTR (methionine synthetase) and SLC19A1 (reduced folate carrier) in the panel of 60 human tumour cell lines established by the NCI for anticancer drug screening and we tentatively associated these polymorphisms with gene expression and drug cytotoxicity as extracted from the public database of the Developmental Therapeutic Programme.

A universal formula based on cystatin C to perform individual dosing of carboplatin in normal weight, underweight, and obese patients.

Purpose: It has recently been shown that it is possible to improve the prediction of carboplatin clearance by adding plasma cystatin C level (cysC), an endogenous marker of glomerular filtration rate, to the other patient characteristics routinely used for carboplatin individual dosing, namely serum creatinine (Scr), actual body weight (ABW), age, and sex. This multicenter pharmacokinetic study was done to evaluate prospectively the benefit of using cysC for carboplatin individual dosing.

Experimental Design: The 357 patients included in the study were receiving carboplatin as part of established protocols.

Quantitation of imidazo[1,2-a]quinoxaline derivatives in human and rat plasma using LC/ESI-MS.

Since several years, our group developed quinoxalinic compounds. Among the synthesized compounds, in the imidazo[1,2-a]quinoxaline series, EAPB0203 has shown interesting activities both on melanoma and lymphoma. The structure of EAPB0203 has been modulated and a new compound, EAPB0503, exhibits an in vitro cytotoxic activity on melanoma cancer cell line 7-9 times higher than EAPB0203.

New imidazo[1,2-a]quinoxaline derivatives: synthesis and in vitro activity against human melanoma.

New imidazo[1,2-a]quinoxaline analogues have been synthesized in good yields via a bimolecular condensation of 2-imidazole carboxylic acid, followed by a coupling with ortho-fluoroaniline and subsequent substitution on the imidazole ring by Suzuki Cross-coupling reaction using microwave assistance. Antitumor activities of these derivatives were evaluated by growth inhibition of A375 cells in vitro. All compounds exhibited high activities compared to imiquimod and fotemustine used as references.

HPLC with UV or mass spectrometric detection for quantifying endogenous uracil and dihydrouracil in human plasma.

Background: We developed and compared 2 different methods for quantifying uracil (U) and dihydrouracil (UH(2)) in BSA and human plasma. Special attention was paid to the selectivity/specificity and the absence of a matrix effect. The UH(2)/U ratio is intended as a biomarker to identify patients with deficiency in 5-fluorouracil metabolism.

In vitro and in vivo anti-tumoral activities of imidazo[1,2-a]quinoxaline, imidazo[1,5-a]quinoxaline, and pyrazolo[1,5-a]quinoxaline derivatives.
