Iressa Covered Medication Iressa gefitinib tablets ; 250mg What it Does and How It's Used Lung cancer is the leading cause of cancer death in men and women in the United States. An estimated 157, 200 Americans will die in 2003 from lung cancer. Non-small cell lung cancer NSCLC ; is the most common type of lung cancer, accounting for almost 80% of lung cancers. NSCLC include adenocarcinomas 40% ; , squamous cell carcinomas 30% ; , and large cell carcinomas 10-15% ; . NSCLC is associated with prior smoking, passive smoking, or radon exposure. NSCLC is characterized by stages 0-IV. Each stage indicates a more extensive spread of the cancer cells throughout the body. Stage 0-II patients have cancer that can be removed by surgery. Stage III consists of patients with lung cancer that has spread to nearby tissues or lymph nodes. Stage IV patients have lung cancer that has spread throughout other parts of the body. Patients with advanced stage NSCLC have a survival rate of less than 5%. Treatment for NSCLC includes surgery, radiation, chemotherapy, or combination of these therapies depending on the extent and stage of the disease. Iressa is the first in a new class of oral chemotherapy drugs that inhibit epidermal growth factor receptor EGFR ; -tyrosine kinase, an enzyme that regulates the proliferation and survival of cancer cells. Iressa can achieve at least a 50% decrease in tumor size in about 10% of patients treated. Iressa when added to platinum or taxoid-based chemotherapy did not demonstrate any increase in tumor response rates, time to progression, or overall survival. Iressa is indicated as a last line treatment option for patients with locally advanced or metastatic NSCLC who failed both platinum-based and docetaxel chemotherapies, and Tarceva erlotinib ; treatment. Iressa is indicated as monotherapy. The Iressa Access Program effective on Sept. 15, 2005 ; limits the use of Iressa to patients who are currently receiving and benefiting from Iressa, or who have received and benefitted from Iressa in the past. New patients should not receive Iressa . Iressa is available as 250mg tablets for oral administration once daily. Treatment Cost AWP: 42.26 for a 30 day supply at a dose of 250mg once daily. Rationale for Coverage Authorization To provide coverage for Iressa only for non-small cell lung cancer in situations where the disease has progressed following specific chemotherapy. Benefit Design Coverage is determined through prior authorization for every claim. Coverage Authorization Design Coverage for gefitnib Iressa ; is provided for use as monotherapy treatment of locally advanced or metastatic non-small cell lung cancer in situations where there is documented disease progression following treatment with either docetaxel Taxotere ; or platinum-based chemotherapy regimen and as well as treatment with Tarceva, or in situations where the patient is not a candidate to receive any further chemotherapy. Coverage duration: benefit approved for 12 months initially and is renewable for 3 months in situations where the patient has demonstrated improved symptoms and no further disease progression while on therapy.

Power switching semiconductors are used in inverter systems with DC-Link. Due to high switching frequencies, harmonics and line distortion may be generated. It is important that the new designs reduce these influences and fulfill the EMI filtering requirements according to EMI EMC VDE 0871 and other. The noise level can be reduced by up to 10dB when the input rectifier is equipped with Semi-fast diodes and is therefore optimised for turn off; resulting in a lower peak recovery current compared to non-optimised and normal rectifier diodes. The noise level can be further reduced approximetely by another 5dB when using rectifier bridges equipped with Fast 80 Recovery Epitaxial Diodes FRED ; like module types VBE single phase bridge ; or VUE three phase bridge ; . However these are more expensive but may be necessary in some applications to fulfill the VDE or other standards. This behaviour has a direct influence on the design of the EMI filter networks with its capacitors and inductors of which the size and costs can be reduced. More detailed information is available in the IXYS application note D98005E "Input Rectifiers with Semi-fast Diodes for DC Link" on ixys and eszopiclone.

Erlotinib, like gefitinib, is an ATP-competitive inhibitor of the EGFR TK Fig. 5 ; . Erlotinib also appears to be particularly effective in lung cancers with BAC histology and in patients who are never smokers, but the drug's clinically relevant target in tumors has not yet been documented. To see whether lung tumors sensitive to erlotinib also contained mutations within the TK domain of EGFR, we analyzed exons 1824 in seven tumors from patients who demonstrated a partial response while on a Phase II trial of this agent in BAC. Five tumors contained mutations, two of which were multinucleotide in-frame deletions within exon 19 near the ATP-binding site.
To medication treatment is supported by observations of significant depressive reactions in subjects with limited or no past medication trials. The -methylparatyrosine induced depressive reaction does not represent a true trait finding, since actively depressed subjects who are medication free do not typically experience significant changes in their depressive symptoms17; however, results from a smaller sample contradict this finding.19, 35 The results of our study are consonant with hypotheses of catecholaminergic dysfunction in depression. In support, postmortem studies of depressed suicide victims examining the locus ceruleus LC ; have revealed diminished density of noradrenergic transporter sites36 and up-regulation of TH.37 Conversely, all classes of antidepressant medications were found to reduce TH levels in the LC of rodents, 38 whereas stress and catecholaminedepleting agents increase TH levels.39, 40 Importantly, -methylparatyrosine administration may mediate behavioral effects via disruption of dopaminergic function as would be consistent with preclinical data ; or may have physiologically important secondary effects that directly attribute to the behavioral findings. For example, catecholamine-depleting agents have been associated with alterations in LC firing rate, 40 neuropeptide Y levels, 41 corticotropin-releasing hormone CRH ; levels, 42 and acetylcholine levels.43 Conjecture on the mechanism of this -methylparatyrosineinduced depressive reaction in medication-free, euthymic subjects with a history of major depression must involve consideration of putative trait abnormalities of the catecholaminergic system. Replicated trait findings include reduced tyramine sulfate conjugation following oral tyramine administration44-46 and blunted growth hormone response to intravenous clonidine hydrochloride administration47, 48 in unipolar depressed subjects. The former finding has unclear pathophysiological significance.44 The latter finding suggests that diminished postsynaptic 2-adrenergic function may be a persistent abnormality in subjects with a history of major depression. Potentially, -methylparatyrosine administration results in diminished noradrenergic output, hence diminishing postsynaptic 2-adrenergic stimulation. In vulnerable subjects, with reduced postsynaptic 2 adrenergic responsiveness, this further reduction may lead to depressive symptoms. Despite the small sample size of our study, a correlation between baseline plasma cortisol levels and severity of the -methylparatyrosineinduced depressive reaction was observed P .59 and P .04, respectively ; . Subjects with higher baseline cortisol levels were proportionately more dependent on intact catecholamine function for maintaining a euthymic state. This finding is consistent with a mixed literature suggesting that abnormalities of cortisol regulation ie, higher levels after dexamethasone administration ; may correlate with higher basal levels of MHPG.49 Furthermore, such persistent dexamethasone nonsuppression in treatment responders is associated with a vulnerability to relapse, 24 as may be persistent elevated CSF levels of CRH.50 Speculation on the mechanism of this correlation based on observations of plasma cortisol levels would be premature and would be furthered by assessment of dexamethasone sup and ethionamide.

Synopsis According to data presented by Genentech and OSI Pharmaceuticals at the annual meeting of the American Society of Clinical Oncology, additional data from a randomised Phase III clinical trial of Tarceva erlotinib ; in advanced pancreatic cancer show that it significantly improves survival when added to gemcitabine chemotherapy in first-line pancreatic cancer compared to gemcitabine alone. The international study was a double-blind, placebo-controlled Phase III trial evaluating Tarceva in patients with locally advanced or metastatic pancreatic cancer. The study randomised 569 patients to receive either gemcitabine plus concurrent Tarceva or gemcitabine plus placebo. According to the researchers, the study met its primary endpoint by demonstrating a statistically significant 23.5% improvement in overall survival or a hazard ratio of 0.81 ; for patients on combination treatment, when compared to patients receiving gemcitabine plus placebo. In addition to the improvement in overall survival, 24% of patients receiving Tarceva plus gemcitabine were alive after one year compared to 17% of patients receiving gemcitabine plus placebo, a 41% increase in one-year survival. Additionally, median survival in the Tarceva plus gemcitabine arm was 6.4 months compared to 5.9 months in the gemcitabine plus placebo arm. Progression-free survival in the Tarceva plus gemcitabine arm was also significantly improved by 32% or a hazard ratio of 0.76 ; . There was virtually no difference in tumour response 9% in patients receiving Tarceva plus gemcitabine versus 8% in the gemcitabine plus placebo arm. ; There were no significant differences in overall survival for patients whose tumours were shown to be EGFRpositive hazard ratio 0.74, n 86 ; versus those whose tumours were shown to be EGFR-negative hazard ratio 0.82, n 76 ; . Based on these data OSI has submitted to the FDA, a supplemental New Drug Application for Tarceva in pancreatic cancer and etodolac.

Conventional cytotoxic chemotherapeutic agents is commonly used in NSCLC patients. Moreover, RRs to regimens used as a first-line therapy do not reach that of gefitinib 22 ; . The present study revealed no differences in RR or TTP for chemotherapy according to EGFR mutational status and therefore it is conceivable that patients with an EGFR mutation may benefit more from gefitinib than from conventional chemotherapeutic agents. Large scale prospective studies of gefitinib as a front-line therapy in advanced NSCLCs are warranted. The mutational activation of K-ras was reported to be associated with an adverse effect on survival in NSCLC patients and a lack of sensitivity to gefitinib or erlotinib 23, 24 ; . In our study, the presence of a K-ras mutation was found to exert an adverse effect on patients treated with first-line platinum-containing or paclitaxel-containing regimens in agreement with the previous reports, although not reaching statistical significance probably due to the small sample size analyzed 25 ; . P-Erk and p-Akt expression status showed no correlation to chemotherapy responses, except for p-Erk expression status and gemcitabine-containing regimens, where p-Erk expression was significantly related to gemcitabine response, although higher RR did not translate into longer TTP. Interestingly, all responders to gemcitabine-containing regimens showed p-Erk expression. Analysis of patients who received gemcitabine as a second-line regimen only also revealed significant association between p-Erk and response data not shown ; . Our results suggest that it may be undesirable to use gemcitabine in patients whose tumors do not express p-Erk. In a previous study, patients with tumors not expressing p-Erk were found to respond poorly to gefitinib and it is possible that patients who are resistant to gefitinib with tumors not expressing p-Erk may benefit from gemcitabine 21 ; . The mechanism linking p-Erk expression and gemcitabine is not known, though it was reported that Erk activation by phosphorylation during chemotherapy mediates gemcitabine-induced apoptosis in NSCLC cells 26 ; . However, the association between pretreatment p-Erk status and gemcitabine sensitivity has not been investigated. Considering the small patient number and retrospective design of the present study, further studies with a larger number of patients are warranted to confirm the effect of p-Erk status on response and survival with gemcitabine treatment. P-Akt has been reported to confer chemoresistance and radioresistance in NSCLC cell lines 27 ; . In recent study, p-Akt protein levels assessed by western blotting and semiquantitative densitometry were associated with a favorable prognosis in patients with NSCLC who underwent surgery alone, but p-Akt expression by immunohistochemistry did not correlate with the prognosis 28 ; . Our data did not show any significant difference in RRs or TTPs for chemotherapic agents according to p-Akt expression by immunohistochemistry. In conclusion, the presence of an EGFR mutation did not affect responses to platinums, paclitaxel or gemcitabine. In addition, our results suggest that it may be undesirable to use gemcitabine for patients with tumors not expressing p-Erk and ertapenem.
