Debio 0617B Inhibits Growth of STAT3-Driven Solid Tumors through Combined Inhibition of JAK, SRC, and Class III/V Receptor Tyrosine Kinases.

Tumor survival, metastases, chemoresistance, and escape from immune responses have been associated with inappropriate activation of STAT3 and/or STAT5 in various cancers, including solid tumors. Debio 0617B has been developed as a first-in-class kinase inhibitor with a unique profile targeting phospho-STAT3 (pSTAT3) and/or pSTAT5 in tumors through combined inhibition of JAK, SRC, ABL, and class III/V receptor tyrosine kinases (RTK). Debio 0617B showed dose-dependent inhibition of pSTAT3 in STAT3-activated carcinoma cell lines; Debio 0617B also showed potent antiproliferative activity in a panel of cancer cell lines and in patient-derived tumor xenografts tested in an in vitro clonogenic assay.

[Rehabilitation after total knee arthroplasty of hip and knee].

Numbers of total hip and knee arthroplasties are increasing on a regular basis. Clinical pathways tend to shorten the duration of hospitalization in acute care after surgery. Therefore, the preoperative preparation of the patient and his abilities for postoperative rehabilitation should be carefully addressed.

Recent studies highlight that the exposure to polluted air can increase the incidence of diseases and deteriorate the quality of life. Hence, it is necessary to develop tools for real-time air quality monitoring, so as to allow appropriate and timely decisions.

Analysis of neurosensory adverse events induced by FOLFOX4 treatment in colorectal cancer patients: a comparison between two Asian studies and four Western studies.

The grades of neurosensory adverse events (NSAEs) induced by FOLFOX4 treatment were compared between Asian and Western colorectal cancer patients and correlated with cumulative oxaliplatin doses. A total of 3359 patients treated with FOLFOX4 were analyzed: 1515 from two Asian studies (Japanese Post Marketing Surveillance [J-PMS] and MASCOT) and 1844 from four Western studies (EFC2962, N9741, EFC4584, and MOSAIC). The onset of NSAEs was analyzed in terms of treatment duration and cumulative dose of oxaliplatin.

Safety analysis of FOLFOX4 treatment in colorectal cancer patients: a comparison between two Asian studies and four Western studies.

Purpose: Oxaliplatin-based therapy, notably FOLFOX4 (5-fluorouracil, leucovorin, and oxaliplatin), is a standard regimen approved globally for the treatment of metastatic colorectal cancer, and as adjuvant treatment of colon cancer. As part of the Japanese submission for the adjuvant indication, the safety profile of FOLFOX4 regimen was compared in Asian and Western patients.

Patients And Methods: A total of 3359 patients with colorectal cancer treated with the FOLFOX4 regimen were included in the analyses: 1515 from 2 Asian studies (Japanese Post Marketing Surveillance and Multicenter Asia Study in Adjuvant Treatment of Colon Cancer with Oxaliplatin/5-FU/LV), and 1844 from 4 Western studies (EFC2962, N9741, EFC4584, and Multicenter International Study of Oxaliplatin/5-Fluorouracil/Leucovorin in the Adjuvant Treatment of Colon Cancer).

Phase II of oral gimatecan in patients with recurrent epithelial ovarian, fallopian tube or peritoneal cancer, previously treated with platinum and taxanes.

Background: A prospective phase II study was conducted to evaluate the efficacy and toxicity of oral gimatecan in patients with recurrent epithelial ovarian, fallopian tube or peritoneal cancer.

Patients And Methods: Patients had a maximum of three prior chemotherapy lines with no more than two prior platinum-containing regimens and a progression-free interval after the last dose of platinum <12 months. A total dose of 4 mg/m(2)/cycle (0.

Oxaliplatin, an anticancer agent that affects both Na+ and K+ channels in frog peripheral myelinated axons.

The use of oxaliplatin, a relatively new chemotherapeutic agent, is somewhat limited since it produces a specific peripheral neuropathy regarding other neurotoxic anticancer platinum analogues. In order to investigate the mechanism of such a peripheral neuropathy, the effects of 1-100 micromol/l oxaliplatin were assessed on the nodal ionic currents of single frog myelinated axons as a model of peripheral excitable membranes. Oxaliplatin decreased both Na(+) and K(+) currents in a dose-dependent manner and within 5-10 min, without producing any marked changes in the current kinetics.

A phase II study was conducted to evaluate the safety and efficacy of an oxaliplatin (OXA)/vinorelbine (VNB) combination in metastatic breast cancer (MBC) patients pre-treated with anthracyclines and taxanes. Patients received OXA at 130 mg/m (2-h i.v.

Influence of oxaliplatin on 5-fluorouracil plasma clearance and clinical consequences.

Unlabelled: The influence of oxaliplatin (OXA) on 5-fluorouracil (5-FU) plasma clearance was investigated.

Patients And Methods: A group of 29 patients with advanced colorectal cancer refractory to prior weekly 8-h 5-FU infusion plus bolus folinic acid (FA), received the same combination plus OXA at 130 mg/m(2) every 3 weeks, OXA plus 5-FU plus FA on day 1, and 5-FU plus FA on days 8 and 15. Steady-state 5-FU concentrations in plasma were measured weekly and 5-FU clearance was calculated.

Factors predicting efficacy of oxaliplatin in combination with 5-fluorouracil (5-FU) +/- folinic acid in a compassionate-use cohort of 481 5-FU-resistant advanced colorectal cancer patients.

A statistical analysis was performed on the patient data collected from two compassionate-use programmes using oxaliplatin (Eloxatin(R)) + 5-fluorouracil (5-FU) +/- folinic acid (FA), to identify predictive factors for oxaliplatin-based salvage treatment in patients with 5-FU-resistant advanced colorectal cancer (ACRC). 481 5-FU-resistant ACRC patients, most with performance status < or = 2, > or = 3 involved sites, and > or = 2 prior lines of chemotherapy, received oxaliplatin + 5-FU +/- FA. Prognostic factors associated with overall response rate (ORR), time to progression (TTP) and overall survival (OS) were identified using univariate and multivariate logistic and/or Cox proportional hazards analyses.

Use of the ratio of time to progression following first- and second-line therapy to document the activity of the combination of oxaliplatin with 5-fluorouracil in the treatment of colorectal carcinoma.

Background: It has been proposed that the activity of a second-line treatment regimen can be documented by showing that the time to progression (TTP) following second-line therapy is longer than the TTP following first-line therapy in the same patients.

Patients And Methods: The ratio of TTP during first and second-line therapy, identified as the growth modulation index (GMI), was determined in 34 patients with advanced colorectal cancer. First-line chemotherapy consisted of one of several schedules of leucovorin (LV)-modulated 5-fluorouracil (5-FU) or raltitrexed.

Single-agent oxaliplatin in pretreated advanced breast cancer patients: a phase II study.

Purpose: Oxaliplatin (L-OHP), a new platinum analogue, is an active drug in colorectal and ovarian cancer. In this phase II study we explored tolerability and activity of oxaliplatin as a single agent in metastatic breast carcinoma patients.

Patients And Methods: Fourteen anthracycline pretreated advanced breast cancer patients were enrolled.

Factors predicting for efficacy of oxaliplatin in combination with 5-fluorouracil (5-FU)+/-folinic acid (FA) in a compassionate-use cohort of 370 5-FU-resistant advanced colorectal cancer (CRC) patients.

Univariate and multivariate analyses were performed on data from 370 5-fluorouracil (5-FU)-resistant advanced colorectal cancer patients treated with oxaliplatin (Eloxatin)/5-FU+/-folinic acid (FA) to identify prognostic factors for oxaliplatin-based treatment. The response rate was 14.6% (95% confidence interval (CI): 11.

Overcoming resistance to chronomodulated 5-fluorouracil and folinic acid by the addition of chronomodulated oxaliplatin in advanced colorectal cancer patients.

The addition of oxaliplatin (L-OHP) to a 5-fluorouracil (5-FU)/ leucovorin (FA) regimen was retrospectively evaluated in 35 consecutive advanced colorectal cancer patients after progression of disease. L-OHP, 25 mg/m2/day, was infused from 10.00-22.

Clinical pharmacokinetics of oxaliplatin: a critical review.

Oxaliplatin (cis-[(1R,2R)-1,2-cyclohexanediamine-N,N'] oxalato(2-)-O,O'] platinum; Eloxatine) is a novel platinum coordination complex used for the treatment of metastatic colorectal carcinoma in combination with fluoropyrimidines. The objective of this review is to integrate the key data from multiple studies into a single, comprehensive overview of oxaliplatin disposition in cancer patients. The pharmacokinetics (PKs) of unbound platinum in plasma ultrafiltrate after oxaliplatin administration was triphasic, characterized by a short initial distribution phase and a long terminal elimination phase (t1/2, 252-273 h).

Pharmacokinetics of oxaliplatin in patients with normal versus impaired renal function.

Purpose: The pharmacokinetics (PK) of platinum was investigated and compared in patients with normal (NRF) and impaired renal function (IRF), after they had received oxaliplatin at the recommended dose and delivery modality.

Methods: Oxaliplatin was administered at 130 mg/m(2) as a 2-h infusion without hydration. Patients were recruited and classified according to their creatinine clearance (CrCl > or < 60 ml/min), calculated using the Cockcroft and Gault formula.

Oxaliplatin added to 5-fluorouracil-based therapy (5-FU +/- FA) in the treatment of 5-FU-pretreated patients with advanced colorectal carcinoma (ACRC): results from the European compassionate-use program.

Purpose: To provide evidence for the therapeutic efficacy of oxaliplatin (Eloxatin) when given as a 2-6-hour i.v. infusion, alone or in combination with 5-fluorouracil/folinic acid (5-FU +/- FA) in patients with advanced colorectal carcinoma (ACRC) who have failed 5-FU-based therapy.

Long-term survival of patients with unresectable colorectal cancer liver metastases following infusional chemotherapy with 5-fluorouracil, leucovorin, oxaliplatin and surgery.

Context: Long-term survival of patients with metastatic colorectal cancer has been achieved only in patients who underwent complete resection of metastases. Such surgery could be performed in a greater proportion of patients if effective chemotherapy could downstage previously unresectable metastases. This approach has been limited by the low tumor response rate achieved with conventional chemotherapy.

A multicenter evaluation of intensified, ambulatory, chronomodulated chemotherapy with oxaliplatin, 5-fluorouracil, and leucovorin as initial treatment of patients with metastatic colorectal carcinoma. International Organization for Cancer Chronotherapy.

Background: The combination of 5-fluorouracil (5-FU), leucovorin (LV), and oxaliplatin (I-OHP) was shown to be both more active against metastatic colorectal carcinoma and better tolerated if the drug delivery rate was chronomodulated according to circadian rhythms rather than constant. This allowed the authors to intensify the three-drug chronotherapy regimen and to assess its activity as the initial treatment of metastatic colorectal carcinoma patients in ten centers from four countries.

Methods: Patients with previously untreated and inoperable measurable metastases from colorectal carcinoma received a daily administration of chronomodulated 5-FU (700 mg/m2/day, peak delivery rate at 04:00 hours), LV (300 mg/m2/day, peak delivery rate at 04:00 hours), and 1-OHP (25 mg/m2/day, peak delivery rate at 16:00 hours) for 4 days every 14 days.

Preliminary results on the activity of oxaliplatin (L-OHP) in refractory/recurrent non-Hodgkin's lymphoma patients.

Background: Many patients with advanced NHL ultimately relapse and require salvage treatment. Oxaliplatin, a diaminocyclohexane (DACH) platinum, has shown a differential spectrum of cytotoxicity with cisplatin, with activity in primary or secondary cisplatin-resistant solid tumors (colon and ovarian cancer). We report the tolerance/activity of this platinum derivate in previously-treated NHL patients.
