PURPOSE: The use of serotonin 5-hydroxytryptamine type 3 receptor antagonists has substantially reduced, but not eliminated, nausea and vomiting in cancer chemotherapy. This study sought to investigate whether efficacy antiemetic treatment with ondansetron tropisetron depends on cytochrome P-450 2D6 (CYP2D6) genotype, hypothesizing that the rapid particularly ultrarapid metabolizers these drugs are at risk being undertreated. PATIENTS AND METHODS: Included were 270 patients receiving their...

BI 2536 is a novel, potent, and highly specific inhibitor of polo-like kinase 1 (Plk1), which has an essential role in the regulation mitotic progression. The aim this trial was to identify maximum tolerated dose (MTD) determine safety, pharmacokinetics, antitumor activity patients who had advanced solid tumors.This phase I followed open label, toxicity-guided, dose-titration design. Single doses (25 250 mg) were administered as 1-hour intravenous infusion; experienced clinical benefit...

Purpose: Serotonin (5-hydroxytryptamine type 3 [5-HT ]) receptor antagonists have substantially reduced but not eliminated nausea and vomiting in patients undergoing cancer chemotherapy. They act through specific binding to the 5-HT 3A , 3B complex. The subunit seems be most important for its functionality. We hypothesized that with genetic variations gene might respond differently antiemetic treatment. Patients Methods: included 242 on their first day of Nausea were documented before twice...

BIBF 1120 is an oral multitargeted tyrosine kinase inhibitor that blocks the activity of vascular endothelial growth factor (VEGF) and other receptors. We have done a phase I study to evaluate safety, pharmacokinetics, pharmacodynamic biomarkers 1120. Patients with advanced refractory solid tumors were treated at doses 150 250 mg twice daily. Drug safety pharmacokinetics evaluated, as baseline post-treatment levels circulating CD117-positive bone marrow-derived progenitor cells plasma...

BIBF 1120 (planned brand name Vargatef) is a novel, oral, triple angiokinase inhibitor targeting three receptor classes involved in blood vessel formation. The objectives of this phase I, open-label dose-escalation study were to determine the safety, tolerability, and maximum tolerated dose (MTD) with pemetrexed patients recurrent advanced-stage non-small cell lung carcinoma.Patients harboring tumor any carcinoma histology, previously treated one first-line platinum-based chemotherapy...

8034 Background: Nintedanib (N) is an oral inhibitor of VEGFR, FGFR, and PDGFR. This global phase 3 study investigated the safety efficacy N + pemetrexed (PEM) vs placebo (P) PEM in patients (pts) with advanced, non-squamous NSCLC previously treated chemotherapy. Methods: Pts were randomized 1:1 to 200 mg po bid 500 mg/m 2 iv q21d (n=353, Arm A) or P (n=360, B). Continuation until PD unacceptable toxicity N, P, PEM, a combination was permitted. 1° endpoint centrally reviewed PFS. The null...

Background: This open-label phase i study with an accelerated titration design was performed to determine the maximum tolerated dose of BI 2536, a potent, highly selective small-molecule polo-like kinase 1 (Plk1) inhibitor. Methods: Patients advanced solid tumours received single 60-minute intravenous infusion 2536 (50–70 mg) on days 1–3 each 21-day treatment course. Recipients without disease progression or untenable toxicity could receive additional courses. The determined based...

The pharmacokinetics and metabolism of BIBF 1120, an oral triple angiokinase inhibitor targeting vascular endothelial growth factor receptor (VEGFR), platelet-derived (PDGFR), fibroblast (FGFR), were studied in healthy male volunteers (n = 8) who had received a single dose 100 mg [14C]-radiolabelled 1120 administered as solution.BIBF was well-tolerated rapidly absorbed; median time to reach maximum plasma concentrations 1.3 h gMean terminal half-life 13.7 h. A relatively high apparent total...

Melphalan is associated with severe side effects such as mucositis, diarrhea, and myelosuppression. We investigated how much the individual severity of these predicted by pharmacokinetics. In addition, we studied glutathione S-transferase GSTM1, GSTT1, GSTP1 polymorphisms in relation to adverse events. A high interindividual pharmacokinetic variability was observed 84 patients. There a linear correlation between creatinine melphalan clearance (P=0.0004). Patients treated dose ⩾70 mg/m2 had...
