How Erlotinib is given:
In conclusion, we experienced the first successful case of erlotinib rechallenge after both gefitinib- and erlotinib-induced ILDs. In a case of EGFR-TKI-induced ILD, if the imaging does not show DAD pattern, and if no alternative option is available, EGFR-TKI rechallenge with concurrent glucocorticoid administration and gradual increase of dosage, under strict informed consent, has the potential to achieve better survival.

Smoking also dramatically increases activity of CYP1A2, another enzyme involved in erlotinib metabolism and this is hypothesized to be one reason for lack of efficacy of the drug in smokers, due to increased clearance (Li et al 2007 ). Ongoing trials are exploring dose escalation of erlotinib in smokers to see if this can be overcome.
TD52 is a derivative modified from erlotinib ( Figure 1g ). We used two strategies to compare the antitumor activities of TD52 and its mother compound, erlotinib, on HCC cells. First, we used MTT assay to evaluate cell viability after exposure to TD52 or erlotinib at the indicated doses for 48   h. As shown in Figure 1a. TD52 caused greater reduction in cell viability than erlotinib in all the HCC cell lines tested including HA22T (IC 50 = 0.9   μ mol / l), Hep3B (IC 50 = 0.9   μ mol / l), PLC5 (IC 50 = 0.8   μ mol / l) and Sk-Hep1 (IC 50 = 1.2   μ mol / l). To further evaluate the cell apoptosis induced by the treatments, all four cell lines were treated with TD52 and erlotinib at the indicated concentration for 24   h and the percentages of sub-G1 cells were determined by flow cytometry ( Figure 1b ). Results of sub-GI analysis echoed the findings observed in the MTT assay, that is, they showed that TD52 had more potent antitumor effects on HCC cells than erlotinib. To better characterize the antitumor properties of TD52, annexin-V / propidium iodide (PI) double-staining assay, western blot analysis, cell cycle analysis and DNA fragmentation assay were performed ( Figures 1c–e. Supplementary Figures 1 and 2 ). As indicated by the results of western blotting, TD52 treatment caused the activation of caspase-9, caspase-3 and subsequent cleavage of poly (ADP-ribose) polymerase (PARP) in a dose-dependent manner ( Figure 1d ). Furthermore, co-treatment of TD52 and z-VAD-fmk, the pan-caspase inhibitor, reduced the pro-apoptotic effects of TD52 ( Figure 1f ). Also, DNA fragmentation of cancer cells was induced by TD52 at relatively low concentration (1   μ mol / l, 24   h; Figure 1e ). In addition, by staining cells with annexin-V-FITC / PI, we demonstrated that the treatment of TD52 induced both apoptosis and necrosis of cancer cell ( Figure 1c and Supplementary Figure 1 ). After 48   h incubation with TD52 at 2.5   μ M or higher doses, the extents of cancer cell death, included apoptotic and necrotic death, were 50 % or more in the four different HCC cells ( Figure 1c ). Interestingly, we found that Hep3B cell was more sensitive to TD52-induced necrotic cell death, while apoptotic cell death was responsible for larger proportion of cell death in HA22T, PLC5 and Sk-Hep1 cells at the same dose range. Using cell cycle analysis, we found that the treatment of TD52 also significantly increased the percentage of S-phase arrest cancer cells at doses higher than 3   μ M (Supplementary Figure 2 ). Moreover, the effects of TD52 were independent of EGFR kinase inhibition ( Figure 1h ). Together, these results suggest that the erlotinib-derivative TD52 exhibits more potent antitumor activity than erlotinib, and that this activity is independent of EGFR kinase inhibition.

Ricerca tarceva 100 Ciao Robbis,
Cases of acute renal failure or renal insufficiency (including fatalities) with or without hypokalemia have been reported. Some were secondary to severe dehydration due to diarrhea, vomiting, and/or anorexia while others were confounded by concurrent chemotherapy use. In the event of dehydration, particularly in patients with contributing risk factors for renal failure (eg, pre-existing renal disease, medical conditions or medications that may lead to renal disease, or other predisposing conditions including advanced age), TARCEVA therapy should be interrupted and appropriate measures should be taken to intensively rehydrate the patient. Periodic monitoring of renal function and serum electrolytes is recommended in patients at risk of dehydration (see Adverse Reactions and DOSAGE AND ADMINISTRATION - Dose Modifications sections).
