Irinotecan half life

ABSTRACT: A blocking enzyme-linked immunosorbent assay was used to test 97 serum samples from big brown bats Eptesicus fuscus ; captured in six counties in Illinois between May 2002 and February 2004 for West Nile virus WNV ; antibodies. One female big brown bat tested positive for WNV antibodies. Samples of kidney, liver, and heart tissue were collected from 312 bats of seven species that were submitted to the Illinois USA ; Department of Public Health or the Illinois Department of Agriculture diagnostic laboratories between January 2001 and December 2003. Tissue samples were tested for WNV using TaqMan reverse transcriptase polymerase chain reaction and all were negative. Prevalence of WNV antibodies in the bats 1% ; was lower than previously reported for other flaviviruses, but similar to the prevalence 2% ; of WNV antibodies reported in bats from New Jersey and New York, USA. Additional research is needed to determine potential impact of WNV infections on bats and to determine whether they play a role in the WNV transmission cycle. Key words: Antibodies, bats, Chiroptera, Illinois, survey, West Nile Virus.

At this meeting, dengue clinicians and epidemiologists discussed how best to classify and treat dengue cases according to their severity, and concluded that a multicentre prospective clinical study is needed to consolidate the current dengue case classification and to better identify early warning signs of severe dengue across regions, age groups and nutritional levels. A research protocol for validating and implementing optimized treatment guidelines was further developed; this multicentre study will be funded by the INCO programme of the European Commission with complementary funding from TDR.

In the last few years, the options of treatment for patients affected by advanced colorectal cancer have considerably increased. Indeed, besides 5-fluorouracil 5-FU ; , which still remains a cornerstone for the management of these patients [1], novel drugs have recently shown appreciable growth inhibitory effects in this disease. Oxaliplatin OXA ; has been extensively evaluated in colorectal cancer [210]. Although it has a demonstrated activity as a single agent [3, 4], OXA has been usually combined with leucovorin-modulated 5-FU [5]. Initial studies were carried out using both cytotoxic drugs in a 5-day chronomodulated infusion [6, 7]. However, comparable results were subsequently reported with OXA administered as a short infusion before a 5-day chronomodulated [8], or a 2-day flat infusion of 5-FU [9, 10]. In a randomised trial, this biweekly regimen was compared with the same 5-FU infusion without OXA: a significantly greater response rate, and a significantly longer time to progression, were reported for the combination arm [10]. Irinotecan IRI ; has also demonstrated a significant activity in colorectal cancer patients [1016]. In first-line use, IRI alone was proven as effective as the standard leucovorinmodulated 5-FU monthly regimen [14]. Moreover, the addition of IRI to leucovorin-modulated 5-FU has been compared with modulated 5-FU in three randomised studies. All these studies reported a significantly greater response rate, and a significantly longer time to progression, for the combination arm [1416]. Two of these trials also demonstrated a substantial survival gain by the addition of IRI [14, 15]. Therefore, for patients unexposed to 5-FU, or showing a late recurrence after previous 5-FU-based treatment, both doublets of either OXA or IRI combined with modulated 5-FU may be considered as suitable options, capable of improving the response rate and prolonging the time to progression in comparison with 5-FU alone. The choice between these two regimens depends more on considerations about their tolerability than on substantial differences in antitumour activity. In addition, a cross-over design at the time of first progression may represent a new strategy of management, which has been claimed to obtain an unprecedented median survival time in excess of 20 months [17]. On the contrary, the treatment options are much less effective for patients already exposed to 5-FU-based treatment showing an early relapse or progression. Both OXA and IRI have been employed in these refractory patients with only moderate benefit on survival [4, 9, 12, 13]. In detail, IRI as second-line treatment has been compared with a 5-FU infusional regimen or with best supportive care alone in two randomised trials, giving a median survival time of 9.810.8 months [12, 13]. As for OXA, it has usually been assessed in addition to leucovorin-modulated high-dose 5-FU.

Patient and Population Samples. A total of 84 patients 43 women and 41 men ; diagnosed with a histologically confirmed malignant solid tumor was assessed for irinotecan pharmacokinetics Table 1 ; . The most common tumor types in this population were of gastrointestinal or pulmonary origin. All patients were of Caucasian descent, were between 34 and 75 years old median, 54 years ; , and were treated between January 1997 and June 2003 at the Erasmus University MCDaniel den Hoed Cancer Center Rotterdam, the Netherlands ; . The inclusion and exclusion criteria, premedication schedules i.e., 8 mg of the 5-hydroxytryptamine-3 receptor antagonist ondansetron, administered i.v., combined with 10 mg of dexamethasone ; , and protocols for treatment of drug-induced side effects were documented previously 18 ; . Irinotecan Aventis Pharma, Hoevelaken, the Netherlands ; was given once every 3 weeks as a 90-minute intravenous infusion. The median dose was 600 mg range, 260 to 875 mg ; . None of the patients received any other concurrent chemotherapy or other drugs, 4 food supplements, and or herbal preparations known to interfere with the pharmacokinetics of irinotecan. Eighty-one patients received irinotecan as single-agent therapy, whereas in 3 patients, irinotecan was combined with cisplatin, which has been demonstrated to have no influence on the pharmacokinetics of irinotecan 19 ; . The clinical protocols 18, 20 ; , including blood sampling for the purpose of pharmacokinetic and pharmacogenetic analyses, were approved by the Erasmus University MCEthics Board, and all patients provided written informed consent. Apart from these 84 European Caucasian cancer patients, genomic DNA was extracted from whole blood of 88 Caucasian and isdn.
Table 1. Some of the agents currently being investigated in clinical trials in advanced pancreatic cancer Class of agent Nucleoside analogues Mode of action Gemcitabine Gemzar ; [5156] is an S phase nucleoside deoxycytidine ; analogue diflourodeoxycytidine ; that is phosphorylated to difluorodeoxycytidine triphosphate by deoxycytidine kinase. Gemcitabine also stimulates deoxycytidine kinase and inhibits both ribonucleotide reductase and deoxycytidine monophosphate deaminase. Gemcitabine triphosphate is incorporated into nascent DNA to inhibit DNA synthesis. The fixed dose rate regimen may be better [57]; being used in numerous trials of doublet and triplet therapies and as a radiosensitiser [6483]. Troxacitabine Troxatyl ; is a dioxolane nucleoside analogue of cytidine that is incorporated into DNA during replication, inhibiting DNA polymerase and DNA synthesis. Unlike other cytidine analogues, troxacitabine is not degraded by cytidine deaminases [84]. Raltitrexed Tomudex ; is a second-generation thymidylate synthase inhibitor with similar efficacy to 5-FU [8587]. Pemetrexed Alimta, LY231514 ; is a new-generation anti-folate with `triple' inhibitory activity against multiple enzymes involved in pyrimidine and purine metabolism. Systemic toxicity is reduced by co-administration of folic acid and vitamin B12 and dexamethasone prevents an associated skin rash [68]. Capecitabine Xeloda ; is an oral, tumour-selective fluoropyrimidine carbamate that is sequentially converted to 5-FU by three enzymes located in the liver and in tumours. The final step is the conversion of 5-deoxy-5-fluorouridine to 5-FU by thymidine phosphorylase in tumours [67]. ZD9331 is a novel oral non-polyglutamated anti-folate thymidylate synthase inhibitor This enzyme is crucial for DNA synthesis and catalyses the reductive methylation of dUMP to form thymidylate, which is subsequently converted to dTTP [88]. Tegafur is also an active 5-FU prodrug that is active taken orally [89]. Topoisomerase-I inhibitors include irinotecan CPT-11, Camptosar ; , camptothecin, topotecan, rubitecan and DX-8951f. Topoisomerase inhibitors impede the DNA helix tortional stress-relieving activity of DNA topoisomerases and also prevent their release from the DNA thus prompting apoptosis. Studies of doublet and triplet therapy are in progress [6972]. These form adducts with DNA inhibiting transcription and replication causing cell death. Oxaliplatin is a third-generation platinum analogue a diaminocyclohexane platinum derivative ; that may have activity in tumours resistant to cisplatin or carboplatin and may have an additive synergistic activity in doublet or triplet therapy. Trials are ongoing with cisplatin [7375] and oxaliplatin [7678]. Oxaliplatin may also have a role as second-line therapy with relapse on gemcitabine [90]. The taxanes include paclitaxel and docetaxel Taxotere ; and are semi-synthetic microtubule inhibitors with a different mechanism of action from the vinca alkaloids. Taxanes bind to -tubulin, promoting microtubule assembly and preventing depolymerisation thus forming stable non-functional complexes and inhibiting the function of the mitotic spindle. The net result is cell cycle arrest and increased sensitivity to radiation [7982]. PS-341 is a reversible and specific inhibitor of the proteasome with activity against pancreatic cancer [91]. The 26S proteasome is a key part of the system that degrades regulatory proteins that govern cell trafficking, transcription factor activation, cell cycle regulation and apoptosis. Celecoxib has been found to be active against pancreatic cancer [92]. Specific cyclo-oxygenase-2 COX-2 ; inhibitors reduce proliferation, inhibit angiogenesis and promote apoptosis. First-generation COX-2 inhibitors include celecoxib and rofecoxib and second-generation agents include parecoxib, valdecoxib and etoricoxib. CV6504 is a novel 5-lipoxygenase and thromboxane A2 synthase inhibitor shown in a phase II to produce stable disease in 32% of patients and a 1-year survival of 25% [93]. CI-994 N-acetyl dinaline, PD 123654 ; is a novel orally active agent causing inhibition of both histone deacetylation and the G1 to S transition phase of the cell cycle [94, 95].

Arrangements of nucleosomes at low ionic strength. The basic unit of the structure is a flat ribbon consisting of two parallel stacks of nucleosomes connected by relaxed spacer DNA. The ribbon is wrapped on the surface of a cylinder to form a fiber with linker DNA that zigzags up and down the helical axis. Worcel proposed that three different ribbons could be constructed, each with a characteristic linking number increment AL ; , which describes the change in the DNA linking number per nucleosome. Worcel favored a AL -1 twisted-ribbon, based on the experimentally determined linking number of SV40 minichromosomes Keller, 1975 ; . Woodcock favored the AL -2 structure, because the DNA appeared to be more relaxed. There are no apparent constraints on the handedness or the diameter of the helix formed, although Woodcock et al. maintained that the diameter should be independent of linker length. The distinguishing features of the twisted-ribbon models are: a ; an alternating sequence of nucleosomes in a two-column ribbon wrapped into a singlestart helix; b ; a helical pitch of 22 nm more, depending upon the length and orientation of the linker DNA; c ; conserved interactions among nucleosomes; and d ; an asymmetric unit composed of two nucleosomes. The crossed-linker models are nonsequential arrangements of nucleosomes cores connected by transverse linker DNA. These models can be characterized by the number and kaletra.

Irinotecan 5-fu

5-FU-based therapy 5-FU alone or in combination with leucovorin ; than tumors with lower levels of TS expression [44]. The most plausible explanation for this observation is that clinically achievable concentrations of intracellular 5FU were insufficient to effectively block TS function in cells with high levels of TS expression. Although methodology of TS assessment and cut-off points used to define "high" and "low" levels of expression have differed from study to study, this observation may provide the theoretical basis for the prospective evaluation of gastrointestinal tumors for TS expression and selection of therapy based on this result. With the availability of drugs such as irinotecan and oxaliplatin that are active against colorectal cancer and exert their cytotoxic effects independently of TS, this hypothesis can now be evaluated in a properly designed, prospective clinical trial. Esophageal and Gastric Cancers Irinotecan is associated with an 18%-33% response rate when used as a single agent in patients with advanced gastric cancer [45, 46, 99]. This makes irinotecan one of the more active single agents for this disease. Given the consistent demonstration of additivity synergy between irinotecan and cisplatin in preclinical model systems, this combination has been explored in the treatment of patients with advanced gastric cancer Table 2 ; . Boku and colleagues treated 44 metastatic gastric cancer patients with irinotecan 70 mg m2 on days 1 and 15 and cisplatin 80 mg m2 day 1 only with cycles repeated every four weeks [47]. He observed a 48% response rate in a mixed group of patients, with 59% of those who had received no prior therapy responding to the irinotecan + cisplatin combination. The most common side effects of this regimen were grade 4 neutropenia 57% of patients ; , grade 3-4 diarrhea 20% of patients ; , and grade 3 nausea 18% of patients. Our study, or, perhaps, the postreceptor signaling mechanisms were influenced is not known. In summary, morphine suppressed nocturnal UCs in the pregnant baboon. The effect of morphine on UCs was primarily due to an inhibition of OT secretion, and perhaps to a much lesser extent to enhanced OT clearance, but it was not related to a direct tocolytic effect on the uterus.

Physiological result. Steady state was apparently reached after 4 consecutive weekly doses, and no accumulation of cetuximab was noted over 26 weeks. Skin toxicity was the major finding observed in a chronic repeat-dose toxicity study in Cynomolgus monkeys at clinically relevant levels. Cetuximab induced severe skin toxicity and lethal complications in monkeys, which exhibited blood levels of approximately 17-fold of those achieved under the standard human treatment regimen. Preclinical data on genotoxicity and local tolerability after accidental administration by routes other than the intended infusion revealed no special hazard for humans. No formal animal studies have been performed to establish the carcinogenic potential of cetuximab or to determine its effects on male and female fertility or its teratogenic potential. Toxicity studies with co-administration of cetuximab and irinotecan have not been performed. No preclinical data on the effect of anti-EGFR antibodies on wound healing are available to date. However, in preclinical wound healing models EGFR selective tyrosine kinase inhibitors were shown to retard wound healing. Efficacy A total of 356 patients with EGFR-expressing metastatic colorectal cancer who had recently failed irinotecan-including cytotoxic therapy and who had a minimum Karnofsky performance status of 60, but the majority of whom had a Karnofsky performance status of 80, received the combination treatment of cetuximab with irinotecan. In the main study, the proportion of responders in the combination group was 22.9% 95%-CI: 17.5% - 29.1% ; . The efficacy of the combination of cetuximab with irinotecan was superior to that of cetuximab monotherapy, in terms of objective response rate and progression-free survival, but no effects on overall survival were demonstrated hazard ratio 0.91, p 0.48 ; . Safety Adverse reactions related to cetuximab may be separated in two categories, those non-specifically related to the antibody character of the compound and those related to EGF-R targeting. Infusionrelated reactions including grade 3 and 4 hypersensitivity reactions were reported in a rather high frequency about 6 and 3%, respectively ; . As regards EGFR targeting, skin and gastrointestinal reactions were most prominent. Cases of late occurring and durable dyspnoea have been reported, although the majority was reported in association with infusion of cetuximab. The possibility that EGFR blockade might enhance an underlying inflammatory condition should be considered. Cases of interstitial lung disorder have been reported, but the incidence appears similar to the reported background incidence, about 0.3%. Special warnings and special precautions for use are adequately addresse din the SPC see section 4.4 ; . The toxicity profile of the combination regimen was dominated by irinotecan-related adverse reactions. The main toxicities of irinotecan are diarrhea, nausea and vomiting, early cholinergic syndrome, alopecia, and neutropenia 107. Patients with metastatic CRC are known to suffer from asthenia and gastrointestinal symptoms 108. Diarrhea, asthenia, nausea, rash, abdominal pain, vomiting, anorexia, stomatitis, leukopenia, alopecia, weight loss, and dehydration were more common in the combination therapy group than in the monotherapy group. In the monotherapy group, there was a tendency for more fever and headache than in the combination therapy group. Fever and headache are common findings in patients treated intravenously with monoclonal antibodies109, 110. Undesirable effects related to cetuximab, include hypersensitivity reactions in approximately 5% of patients during treatment with cetuximab. Approximately half of these reactions are severe. Mild or moderate reactions grade 1 or 2 ; include symptoms such as fever, chills, nausea, rash, or dyspnoea. Severe hypersensitivity reactions grade 3 or 4 ; usually occur during or within 1 hour of the initial cetuximab infusion. Symptoms include the rapid onset of airway obstruction bronchospasm, stridor, hoarseness, difficulty in speaking ; , urticaria, and or hypotension. Conjunctivitis may be expected in approximately 5% of patients. Dyspnoea has been reported in 25% of patients with end stage colorectal cancer. In elderly patients.

Irinotecan warfarin

The preclinical data and support the hypothesis that Drg1 expression may be associated with irinotecan resistance. What is not tested in this data set is whether subsequent irinotecan therapy induced Drg1 expression and, if so, at what point this occurred relative to irinotecan therapy and irinotecan failure. This will require future prospective clinical evaluation and analysis. Furthermore, we previously reported that irinotecan resistance can be overcome by the sequential and timely administration of the cell cycle modulator, flavopiridol 26 ; , and that this potentiation may be related to Drg1 modulation 15 ; . In view of this, we have begun to examine pretreatment and post-treatment tumor biopsies in patients receiving this combination 27 ; . This study represents a large and systematic evaluation of Drg1 in a cohort of patients with metastatic colon cancer to the liver before the era of irinotecan-based therapy. In colon cancer, in contradiction to previous preclinical reports, loss of Drg1 expression does not appear to be solely responsible for the development of metastases. However, its expression may indeed suggest a more indolent course of disease, in support of the previous studies. In this population of patients, the number of metastases resected, and other cellular markers including thymidilate synthase, seemed more predictive of patient survival. This may not be surprising as these patients were treated in the adjuvant setting from 1991 to 1995 where the only cytotoxic drug available to patients was fluorouracil. Our study also supports the preclinical data that suggests high basal Drg1 expression is associated with relative irinotecan resistance. Examining a separate cohort of patients in the current era may give us better insight as to the role of Drg1 with regard to chemotherapy resistance to irinotecan. The modulation of Drg1 and its consequence with regard to irinotecan resistance is continuing to be explored. Based on this study and the published literature to date, it seems that Drg1 may have significant function relative to the malignant phenotype. High expression of Drg1 appears to be associated with differentiation, earlier stage of disease, and with an indolent course of metastatic disease. However, high expression of Drg1 also appears to be associated with relative resistance to irinotecan chemotherapy. Further carefully planned clinical studies are required to clarify these potential roles of this new protein. The role of Drg1 in malignancy continues to be defined and kato.

Duke's researchers are on the cutting edge of developing new therapies for patients and some of the most exciting brain tumor research to date has surrounded bevacizumab Avastin ; . In a recent pilot study published in the February 20, 2007 issue of the journal Clinical Cancer Research, Duke researchers reported that dual therapy with Avastin and the chemotherapy drug irinotecan ; either shrank tumors or restricted their growth in nearly all cases 32 patients with recurrent cancerous brain tumors ; for up to three months longer than comparative therapies. "These results are exciting because of the possible implications for a patient population that currently has the poorest possible prognosis going into treatment, those with malignant brain tumors that have recurred after initial treatment, " said Dr. Friedman. Duke is now participating in an 11-center trial of this combination therapy funded by Genentech, and it is hoped that the results will lead to an FDA approved therapy for patients with brain cancer. "Going forward, we will also explore the efficacy of this treatment in newly diagnosed patients, " Dr. Bigner said. "Ultimately, our hope is that this will offer a real weapon in what is now a very limited arsenal for treating a very challenging cancer and irinotecan.

Plus infusional 5-FU LV FOLFIRI ; improved survival with less toxicity than occurred with IFL, which used a bolus administration of 5-FU, as indicated in the Saltz study. The Saltz and Douillard studies established the superiority of irinotecan plus 5-FU LV combinations in firstline treatment of mCRC, compared with the previous standard 5-FU LV alone. Although not directly comparable, results from these studies indicate that for irinotecan-containing regimens.

Pilot projects are underway to explore opportunities for extending preferential pricing to a wider range of medicines. These are being run in partnership with NGOs in Zambia, Malawi, Uganda, Tanzania and Nigeria. Early observations suggest that the greatest medical need is for basic essential medicines. Furthermore, even when medicines are supplied at the lowest prices, access to treatment may not significantly increase without adequate healthcare infrastructure. The international community made good progress on supporting access to medicines initiatives in 2003. In particular we welcome funding from initiatives such as the Global Fund and the US Emergency Plan for AIDS Relief, as well as the G8 Action Plan on Health that recognises the importance of preferential pricing and preventing product diversion11. However, much more still needs to be done. Research and development There is currently no cure for many of the diseases affecting developing countries, and some existing treatments are becoming less effective due to drug resistance. Investment in R&D for new treatments and vaccines is therefore vital. Public private partnerships PPP ; are essential to fund research where there is no commercially viable market for a potential product. We are working with many governments, UN agencies and other global funding bodies in this area. We believe we are currently the only company researching new vaccines and treatments for all three of the WHO's priority diseases in the developing world HIV AIDS, TB and malaria. We have 16 clinical development programmes for products of relevance to the developing world. Seven of these are aimed specifically at diseases that disproportionately affect developing countries see table, page 12 ; . A number of preclinical projects are also underway and isdn.
