Resminostat plus sorafenib as second-line therapy of advanced hepatocellular carcinoma - The SHELTER study.

Background & Aims: No established therapies for patients with hepatocellular carcinoma (HCC) and progression on first-line sorafenib treatment currently exist. This phase I/II trial investigated safety, pharmacokinetics and potential biomarkers of the histone deacetylase inhibitor resminostat and a combination therapy with resminostat and sorafenib.

Methods: Patients with HCC and radiologically confirmed progression on sorafenib were treated in an exploratory, multi-center, open-label, uncontrolled, non-randomized, parallel group phase I/II study.

First-in-human, pharmacokinetic and pharmacodynamic phase I study of Resminostat, an oral histone deacetylase inhibitor, in patients with advanced solid tumors.

Purpose: This first-in-human dose-escalating trial investigated the safety, tolerability, maximum tolerated dose (MTD), dose-limiting toxicities (DLT), pharmacokinetics, and pharmacodynamics of the novel histone deacetylase (HDAC) inhibitor resminostat in patients with advanced solid tumors.

Experimental Design: Resminostat was administered orally once-daily on days 1 to 5 every 14 days at 5 dose levels between 100 and 800 mg. Safety, pharmacokinetics, pharmacodynamics including histone acetylation and HDAC enzyme activity, and antitumor efficacy were assessed.

The oral, once-daily phosphodiesterase 4 inhibitor roflumilast lacks relevant pharmacokinetic interactions with inhaled budesonide.

This open-label, randomized, 3-period crossover study evaluated the pharmacokinetic interaction potential of roflumilast and budesonide following repeated coadministration to healthy male subjects (N = 12). Treatments consisted of oral roflumilast 500 mug, once daily, orally inhaled budesonide 800 mug, twice daily, and concomitant administration of both treatments for 7 days each. Roflumilast and roflumilast N-oxide in plasma and budesonide serum levels were measured by specific assays.

Dose-proportional intraindividual single- and repeated-dose pharmacokinetics of roflumilast, an oral, once-daily phosphodiesterase 4 inhibitor.

The dose-proportional, intraindividual, single- and repeated-dose pharmacokinetics of roflumilast, an oral, once-daily phosphodiesterase 4 inhibitor under investigation for chronic obstructive pulmonary disease and asthma, was investigated in healthy subjects. In an open, randomized, 2-period, 2-sequence crossover study, 15 subjects received immediate-release tablets of roflumilast 250 or 500 microg as single (day 1) and as repeated, once-daily doses for 8 days (days 5-12). Dose-adjusted point estimates and 90% confidence intervals of test (500 microg)/reference (250 microg) ratios for AUC and Cmax of roflumilast and its pharmacologically active N-oxide metabolite after single and repeated dosing were all within the standard equivalence acceptance range (0.

Roflumilast, a once-daily oral phosphodiesterase 4 inhibitor, lacks relevant pharmacokinetic interactions with inhaled salbutamol when co-administered in healthy subjects.

Objective: Roflumilast is an oral, once-daily phosphodiesterase 4 inhibitor under investigation for the treatment of chronic obstructive pulmonary disease and asthma. In clinical practice, the drug is likely to be co-administered with inhaled bronchodilating beta2-adrenoceptor agonists. Therefore, this study investigated the pharmacokinetic characteristics of roflumilast and its pharmacodynamically active metabolite roflumilast N-oxide when co-administered with orally inhaled salbutamol in healthy subjects.

Investigation of a potential food effect on the pharmacokinetics of roflumilast, an oral, once-daily phosphodiesterase 4 inhibitor, in healthy subjects.

This open, randomized, single-dose crossover study investigated effects of a high-fat meal on the pharmacokinetics of roflumilast and its major active N-oxide metabolite. Twelve healthy subjects received oral roflumilast 500 microg (2 x 250 microg) after overnight fasting and after breakfast. Blood was sampled up to 54 hours for pharmacokinetic profiling of roflumilast and N-oxide.

Identification and characterization of CYP3A4*20, a novel rare CYP3A4 allele without functional activity.

Background: The major drug-metabolizing enzyme cytochrome P450 (CYP) 3A4 is genetically conserved. One outlier of Brazilian descent was found in a clinical pharmacokinetic trial exhibiting a 6-fold higher exposure than expected to an investigational drug, shown to be a CYP3A4 substrate. We aimed to investigate the genetic background of this finding.

Phase II study with 5-fluorouracil and ginkgo biloba extract (GBE 761 ONC) in patients with pancreatic cancer.

The aim of the study was to evaluate the efficacy and tolerability of as well as the quality of life under treatment with 5-fluorouracil (CAS 51-21-8, 5-FU) combined with parenteral GBE 761 ONC (i.e. the ginkgo biloba special extract EGb 761) in patients with pancreatic cancer.

Linearized colorimetric assay for cremophor EL: application to pharmacokinetics after 1-hour paclitaxel infusions.

Cremophor EL (CrEL) is a polyoxyethylated castor oil surfactant used in the intravenous formulation of the anticancer drug paclitaxel (Taxol). Quantitative determination of CrEL in patient samples can be achieved by complexation of the compound with the Coomassie brilliant blue G-250 dye in protein-free extracts [Sparreboom, A., Loos, W.

Clinical phase I study with one-hour paclitaxel infusion.

Background: Paclitaxel (PAC) is one of the major anti-cancer drugs, effective in different tumors. Studies with 24-hour infusion with 135 mg/m2 and a three-hour infusion with 175 mg/m2 showed a significant schedule-dependent toxicity. We evaluated a one-hour infusion schedule within a phase I study to determine the dose limiting toxicity (DLT), the maximum tolerated dose (MTD), and the anti-cancer efficacy.

Phase I study of paclitaxel administered as a 1-hour infusion: toxicity and pharmacokinetics.

Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is one of the most important new drugs used in the treatment of solid tumors. Use of paclitaxel, however, is associated with some toxicity. The main adverse side effects include myelotoxicity, neurotoxicity, hypersensitivity reactions, and asthenia.

[A new measuring device for computer-assisted imaging of the form and flexibility of the spine].

Our aim is to present a new method to examine spinal mobility and spine shape excluding torsional scoliosis. In comparison to measuring devices of the spine used so far, this noninvasive and easy to use method documents altered patterns of intervertebral mobility of the lumbar and thoracic spine. This may lead to a broader application of the triflexometer as a diagnostic tool for orthopedic and rheumatologic diseases that can decrease the frequency of X-ray exposure if used in combination with radiographs.
