. Efficacy and safety of erlotinib monotherapy for Japanese patients with advanced non-small cell lung cancer: a phase II study. J Thorac Oncol 2008 ; 3. 1439 - 45. doi:10.1097/JTO.0b013e31818d6702.
Combination treatment with bevacizumab and erlotinib resulted in an overall response rate of 65% in the hereditary leiomyomatosis and renal cell cancer cohort and 29% in the sporadic papillary renal cell carcinoma cohort.
The serum concentration of Erlotinib can be increased when it is combined with Probenecid.
[0012] Erlotinib obtained by the processes described in the art is not satisfactory from purity point of view. We have repeated the erlotinib synthetic procedures as described in the prior art mentioned above and found that relatively large amounts of impurities were obtained along with erlotinib. Among these impurities, the N-methoxyethyl impurity, namely. N-[(3-ethynylphenyl)-(2-methoxyethyl)]-6,7-bis(2-methoxyethoxy)-4- -quinazolinamine, of formula I:
Erlotinib is an inhibitor of human Epidermal growth factor receptor (EGFR) tyrosine kinase (IC50 = 2 nM) and decreases EGFR autophosphorylation in tumor cells (IC50 = 20 nM). Studies in cell lines and enzyme assays have both shown that erlotinib inhibits EGFR at concentrations significantly lower than those needed to inhibit c-src and v-abl.

Gefitinib was the first EGFR tyrosine kinase inhibitor (TKI) to become available in Europe in an expanded access program in pretreated advanced NSCLC on the basis of the results of two large randomized phase II studies. 2 and 3 Nevertheless, the Iressa Survival Evaluation in Lung Cancer phase III trial comparing gefitinib with best supportive care among 1692 advanced NSCLC patients pretreated with one or two prior chemotherapy regimens, did not show a significant difference in overall survival between gefitinib and placebo (5.6 versus 5.1 month; hazard ratio, 0.89; 95% confidence interval, 0.78–1.03; p = 0.11). 4 On the contrary, erlotinib showed a survival benefit versus placebo in patients with NSCLC after the failure of first-line or second-line chemotherapy in the BR.21 randomized phase III trial (6.7 versus 4.7 months; p = 0.001). 5

Kidney problems: The risks of Tarceva treatment are greater in patients with kidney disorders, and your doctor may need to take additional measures to reduce associated risks. If you develop kidney problems in the course of treatment, it may be necessary to stop treatment;
I know I am replying to a very old posting, however my question relates to Tarceva drug interaction, so I am hoping you will get this message.
The recommended daily dose of TARCEVA is 100 mg taken at least one hour before or two hours after the ingestion of food, in combination with gemcitabine (see the gemcitabine package insert). Treatment should continue until disease progression or unacceptable toxicity occurs.
"We are pleased that the EURTAC study so quickly revealed Tarceva may be a viable alternative to platinum-based chemotherapy in newly diagnosed NSCLC patients with EGFR activating mutations," said Naoki Okamura, chief executive officer, OSI Pharmaceuticals. "The interim analysis of the EURTAC study reinforces the role that Tarceva may have in treating patients beyond the Asian population, which has a historically higher instance of EGFR activating mutations."
Pregnant women are excluded from this study because bevacizumab and erlotinib are anti-cancer agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with these agents, breastfeeding should be discontinued if the mother is treated on this study

Tarceva may have to be replaced with another more effective chemotherapy drug. Radiation therapy to shrink the node and relieve the swelling may also have to be done. Consult with your oncologist as soon as possible so you can be properly assessed.

Gentili Dottori, purtroppo la situazione di mio padre da qualche giorno sta andando via via peggiorando. Temo una ripresa dell'attività delle metastasi cerebrali anche se la tac di 10 giorni fa escludeva ale ipotesi. Tuttavia i segni neurologici sono molto chiari (fortissimi mal di testa, assenza di coordinazione nei movimenti, episodi di vomito). Il medico che lo segue ha instaurato una terapia che prevede 100cc di mannitolo al mattino e 100 cc la sera ed in più continua con il cortisone (soldesam 4mg mattina e sera). Contramal in caso di dolore forte e plasil per il vomito. Vorrei sapere se a vostro modo di vedere esiste ancora qualche possibilità di cura. Sono alla disperazione e lo vedo ogni giorno spegnersi sempre di più. Sarò grato a chiunque possa darmi un aiuto o un suggerimento in questo difficile momento. Riassumo in poche righe la sua storia clinica: luglio 2007: scoperta di adenocarcinoma polmonare al polmone destro con metastasi cerebrali; agosto 2007: radioterapia a bagno sull'intero encefalo; settembre 2007-gennaio 2008: sei cicli di chemioterapia (cisplatino + vinorelbina): regressione della malattia ai controlli. febbraio 2008: trombosi venosa profonda alla gamba sinistra seguita da embolia polmonare trattato con eparina a basso peso molecolare; aprile 2008: stabile alla tac, riduzione dell' embolia polmonare; inizio della terapia con il tarceva; giugno 2008: tac:peggioramento della malattia polmonare, apparentemente stabile al cervello.
