Chemotherapy-induced peripheral neuropathy in cancer patients: a four-arm randomized trial on the effectiveness of electroacupuncture.

Purpose. Chemotherapy-induced peripheral neuropathy (CIPN) is a common and dose-limiting side effect of cytostatic drugs. Since there are no proven therapeutic procedures against CIPN, we were interested to define the role of electroacupuncture (EA) from which preliminary data showed promising results.

Phase I study of telatinib (BAY 57-9352): analysis of safety, pharmacokinetics, tumor efficacy, and biomarkers in patients with colorectal cancer.

Background: Telatinib (BAY 57-9352) is an orally available, small-molecule inhibitor of vascular endothelial growth factor receptors 2 and 3 (VEGFR-2/-3) and platelet-derived growth factor receptor β tyrosine kinases.

Methods: In this multicenter phase I dose-escalation study including a phase II like expansion part, 39 patients with refractory colorectal cancer (CRC) were enrolled into 14 days on / 7 days off in repeating cycles of 28 days (n = 11) or continuous dosing groups (n = 28) to receive ≥ 600 mg telatinib twice-daily (bid).

Results: Hypertension (28%) and diarrhoea (15%) were the most frequent study drug-related adverse events of CTC grade 3.

Antitumor effect of the vascular-disrupting agent ZD6126 in a murine renal cell carcinoma model.

ZD6126 is a vascular-disrupting agent that affects the endothelial tubulin cytoskeleton causing selective occlusion of tumor vasculature and extensive tumor cell necrosis. The present study evaluated the antitumor and antivascular activities of ZD6126 in the clinically relevant murine renal cell carcinoma (RENCA) model and also evaluated biological response to therapy using color Doppler imaging as biomarker. Mice were implanted with RENCA tumor cells (day 0) and established tumors were treated with ZD6126 (100 mg/kg i.

Clinical trials with anti-angiogenic agents in hematological malignancies.

New blood vessel formation (angiogenesis) is not only essential for the growth of solid tumors but there is also emerging evidence that progression of hematological malignancies like multiple myeloma, acute leukemias, and myeloproliferative neoplasms, also depends on new blood vessel formation. Anti-angiogenic strategies have become an important therapeutic modality for solid tumors. Several anti-angiogenic agents targeting angiogenesis-related pathways like monoclonal antibodies, receptor tyrosine kinase inhibitors, immunomodulatory drugs, and proteasome inhibitors have been entered clinical trials or have been already approved for the treatment of hematological malignancies as well and in some instances these pathways have emerged as promising therapeutic targets.

Antitumor and antiangiogenic activity of cediranib in a preclinical model of renal cell carcinoma.

Cediranib is a highly potent and selective vascular endothelial growth factor (VEGF) signaling inhibitor with activity against all three VEGF receptors (VEGFRs) that inhibits angiogenesis and growth of human tumor xenografts in vivo. The present study evaluated the antitumor and antiangiogenic activity of cediranib in the clinically relevant, murine renal cell carcinoma (RENCA) model and its biological response using VEGF and sVEGFR-2 as biomarkers. Mice were treated with cediranib (5 mg/kg/d p.

Phase II STUdy with 3rd- or 4th-line bendamustine (flat dose) therapy in patients with metastatic breast cancer.

Background: Bendamustine is a drug with a favorable side effect spectrum and it offers a chance to overcome tumor resistance in pretreated patients with metastatic breast cancer (MBC).

Patients And Methods: Bendamustine was given as flat dose with 200 mg at days 1 + 2 in MBC patients pretreated with 2-3 different chemotherapies. Therapy was repeated at day 28 or fully recovered neutrophils.

Phase I dose escalation and pharmacokinetic study of BI 2536, a novel Polo-like kinase 1 inhibitor, in patients with advanced solid tumors.

Purpose: BI 2536 is a novel, potent, and highly specific inhibitor of polo-like kinase 1 (Plk1), which has an essential role in the regulation of mitotic progression. The aim of this trial was to identify the maximum tolerated dose (MTD) of BI 2536 and to determine the safety, pharmacokinetics, and antitumor activity in patients who had advanced solid tumors.

Patients And Methods: This phase I trial followed an open label, toxicity-guided, dose-titration design.

Metronomic antiangiogenic therapy with capecitabine and celecoxib in advanced tumor patients--results of a phase II study.

Background: Combined therapy of continuous low dose capecitabine and high dose celecoxib targeting angiogenesis was used in a phase II trial to treat advanced cancer patients. Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) was used to monitor antiangiogenic effects.

Material And Methods: 37 Patients (21 men, 16 women), mean age 60 years, with advanced and progressive cancer of various tumor types were included.

PAC fixed dose: pharmacokinetics of a 1-hour paclitaxel infusion and comparison to BSA-normalized drug dosing.

Background: The aim of this study was to determine the pharmacokinetics (PKs) of a 175-mg fixed dose of paclitaxel (PAC) after a 1-h infusion in cancer patients and to compare them with the PK parameters from a study with a dose normalized to the body surface area (BSA) (100 mg/m2).

Patients And Methods: PAC PKs were studied during the first course of therapy in 13 patients. A fixed dose of 175 mg PAC was administered weekly by a 1-h infusion to patients with advanced cancer.

Treatment of anthracycline extravasation with dexrazoxane -- clinical experience.

Background: Accidental extravasation is a severe complication when administering anthracyclines. We describe 3 cases of extravasation with 3 different anthracyclines.

Patients And Methods: One patient came from another hospital for a second opinion after an epirubicin extravasation.

Angiogenesis and the ET-1/ETA receptor system: immunohistochemical expression analysis in bone metastases from patients with different primary tumors.

Angiogenesis is necessary for the growth of primary tumors and the formation of metastases. It is well known that vascular endothelial growth factor (VEGF) and its receptors play a major role in this process. To date, the formation of bone metastases has been poorly understood.

Anti-angiogenesis therapy:concepts and importance of dosing schedules in clinical trials.

The biological control of angiogenesis is critical to the clinical control of cancer. Understanding the mechanism of formation and regulation of new blood vessel development would open a new avenue for cancer treatment. Intense research effort has revealed a variety of factors which initiate, control and terminate the multi-stage process of angiogenesis, as well as target structures which interfere with this process.

Phase II study of combined 5-fluorouracil/ Ginkgo biloba extract (GBE 761 ONC) therapy in 5-fluorouracil pretreated patients with advanced colorectal cancer.

The aim of the study was to evaluate the efficacy, tolerability and quality of life in 5-fluorouracil (5-FU) pretreated colorectal cancer patients after combined 5-FU and Ginkgo biloba extract GBE 761 ONC (i.e. the Ginkgo biloba special extract EGb 761(R)) therapy.

The pharmacokinetics of a 1-h paclitaxel infusion.

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.
