The most frequent (≥ 30%) adverse reactions in Tarceva-treated patients were diarrhea, asthenia, rash, cough, dyspnea and decreased appetite. In Tarceva-treated patients the median time to onset of rash was 15 days and the median time to onset of diarrhea was 32 days.
Over-expression of Cox-2 in tumor cells was seen in preclinical studies to cause resistance to drugs like Tarceva, which block tumor cell growth by targeting the EGFR, according to Karen Reckamp, M.D. of the University of California at Los Angeles.
Another limitation of the cost-effectiveness analysis was the assumption that both TKI therapies present a similar survival probability after disease progression. The survival probability after disease progression was simulated on the basis of the IPASS overall survival outcomes. This assumption was necessary, as the overall survival results from OPTIMAL are still immature. As a result of this assumption, the PFS benefit of erlotinib was transferred to the overall survival outcome. How strongly this assumption impacts the results is currently difficult to determine. Future CEAs using the final OPTIMAL overall survival data (currently immature) are necessary to eliminate this uncertainty
Always take TARCEVA exactly as your doctor has instructed you. Check with your doctor or pharmacist if you are unsure.
In conclusion, erlotinib offers a potentially cost-effective treatment option for the subgroup of predominantly poor performance patients with NSCLC with EGFR wild-type tumours who develop first-cycle rash and who are considered unfit by clinicians to be treated with first-line chemotherapy.

Erlotinib Hydrochloride inhibits the human epidermal growth factor receptor (HER-1/EGFR) tyrosine kinase.
The response rates and disease control rates in the gefitinib- and erlotinib-treated groups in this study were 76.9% versus 74.4% ( p = 0.575) and 90.1% versus 86.8% ( p = 0.305), respectively, which are consistent with previous studies. 5. 6 and 7 , 9 The response rates and disease control rates of erlotinib were reported to be up to 82% and 96%, respectively, in patients with NSCLC with EGFR mutations, 9 and the response rate of gefitinib ranged from 70% to 80% 5. 6 and 7 in EGFR-mutated NSCLC patients. A previously reported prospective phase II study conducted at our institution also demonstrated 12 that both gefitinib and erlotinib showed similar antitumor activity as second-line treatment for clinically selected patients without known EGFR mutation status.

Genes of the ERBB family encode receptor tyrosine kinases that mediate cellular responses to growth signals. Somatic mutations in the tyrosine kinase domains of two ERBB genes, epidermal growth factor receptor (EGFR) and HER2, have been found in a proportion of lung adenocarcinomas [1 ,2 ,3 ,4 ]. For EGFR, mutations are associated with sensitivity to the small-molecule kinase inhibitors gefitinib (Iressa) [1 ,2 ,3 ] and erlotinib (Tarceva) [3 ].
To test whether YW327.6S2 could enhance the therapeutic index of standard care for NSCLC, we performed combination treatment of YW327.6S2 with epidermal growth factor receptor (EGFR) small-molecule inhibitor (SMI) erlotinib and chemotherapy.
The results of N0177 are in contrast to a single-institution phase II trial of 65 adults with newly diagnosed GBM treated with erlotinib combined with TMZ and RT. In this study from University of California, San Francisco (UCSF), patients not taking EIACs received 100 mg/d of erlotinib during RT and 150 mg/d after RT. 28 After RT, the dose of erlotinib was escalated until the development of tolerable grade 2 rash or the maximum allowed dose of 200 mg/d. The median survival time was 19 months and superior to previous studies performed at UCSF, although it is unclear from the reported abstract whether the historical controls were from the TMZ or pre-TMZ (ie, nitrosourea) era and whether the studies were compared using a prognostic scoring system such as RPA. The superior survival achieved in the UCSF study compared with N0177 was certainly not a result of erlotinib dosing because the dose of erlotinib during RT was actually lower in the UCSF trial and less than half of patients enrolled onto N0177 would have been able to escalate their maintenance erlotinib from 150 to 200 mg/d because half of the patients on N0177 had grade 2 or greater rash. In addition, 22% of patients enrolled onto N0177 stopped treatment as a result of toxicity; therefore, meaningful dose escalation is unlikely to have been helpful. Because the treatment regimens were so similar between the studies, it is quite likely that the differences in survival are a result of differences in patient characteristics.
My mom is using Tarceva (Erlotinib) for last 1 week for non small cell lung cancer. She is also planning to use Iscador (mistletoe) soon. We would like to hear from patients who used the above combination, or any opinion/comments on the above medicine combination.

In conclusion, the relationship among erlotinib plasma concentrations, pEGFR degradation, and tumor growth inhibition in a human tumor xenograft model was appropriately characterized in a quantitative manner by an integral PK/PD model. The intracellular indirect mechanism of action of erlotinib was responsible for the pEGFR inhibition lag behind the measured erlotinib plasma concentration. The IC 50 value for pEGFR degradation was within the minimum and maximum steady-state concentration window of the clinical effective dosage, which provides evidence of the clinical significance of PK/PD modeling based on biomarkers. In the integrated PK/PD model, the pEGFR inhibition was linearly related to the tumor growth inhibition, which provides a thorough understanding of drug action and its therapeutic response. Additionally, the prediction capability of the integrated model was proven by the good prediction of tumor volume data after treatment with 12.5 mg/kg erlotinib. We believe that these PK/PD results will be helpful in understanding the mechanism of action and its therapeutic response and determining the appropriate experimental design in preclinical and clinical studies.
Review: could Tarceva cause Metallic Taste?
Other than a trial her options would look like those of anyone else with an adenocarcinoma nsclc. Here is a blog/post outlining the options and yes alimta and carboplatin are among the top platinum based doublets given to adeno. I’m assuming it is adenocarcinoma because of the mutation, however if she has squamous cell then alimta isn’t an option. Many if not most oncologist today would start a patient with an egfr mutation on tarceva first line so I hope you don’t worry that your mom isn’t getting excellent treatment because of that choice. The links below answer the question of first line treatments. Since your mom had tarceva first the doublets mentioned are used 2nd line.

Non sono stati effettuati studi su donne in gravidanza trattate con erlotinib. Gli studi effettuati su animali hanno evidenziato una tossicita' riproduttiva. Il rischio potenziale per gli esseri umani non e' noto. Si deve raccomandare alle donne in eta' fertile di evitare la gravidanza durante il trattamento. Durante il trattamento e per almeno 2 settimane dopo la fine del trattamento si devono usare metodi contraccettivi adeguati. Nelle donne in gravidanza il trattamento va proseguitosolo nei casi in cui il potenziale beneficio per la madre superi il rischio per il feto. Non e' noto se erlotinib venga escreto nel latte umano. A causa del danno potenziale per il neonato, si deve raccomandare alle madri di non allattare al seno durante il trattamento.

None of the therapeutic strategies evaluated so far involving erlotinib either alone or in combination with conventional adjuvant therapies represent a major success for the treatment of glioblastoma. Therefore, changing the general strategy towards a combined approach with HER1/EGFR TK inhibitors and other targeted agents might provide a more pronounced clinical benefit for patients suffering from this disease.
Erlotinib has better efficacy than gefitinib in adenocarcinoma patients without EGFR-activating mutations, but similar efficacy in patients with EGFR-activating mutations. Wu et al . Exp Ther Med. 2012 Feb;3(2):207-213. PMID: 22969870 .
The recommended daily dose of TARCEVA for non-small cell lung cancer is 150 mg taken at least one hour before or two hours after the ingestion of food. Treatment should continue until disease progression or unacceptable toxicity occurs. There is no evidence that treatment beyond progression is beneficial.

Erlotinib Gefitinib Bevacizumab Vatalanib Multikinaseinhibitor
Purpose: To examine the antitumor activity and tolerability of a combination comprising erlotinib and capecitabine in human colorectal, breast and epidermal cancer xenograft models. Further aims of the study were to examine the effects of single-agent erlotinib therapy on tumor growth, and on thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) levels, (enzymes which activate and deactivate capecitabine, respectively) in tumor tissue. Methods: BALB/c nu/nu mice bearing LoVo and HT-29 (colon cancer), A-431 (vulval cancer), and KPL-4 and MAXF401 (breast cancer) human tumors were treated with erlotinib 100 mg/kg/day and/or capecitabine 359 or 90 mg/kg/day, by oral administration once daily for 14 days. Results: The maximum tolerated dose (MTD) of erlotinib, formulated in carboxymethylcelluose/Tween 80, was identified as 125 mg/kg/day. Erlotinib at a dose of 100 mg/kg/day achieved significant tumor-growth inhibition in the, LoVo, KPL-4, and A-431 models. Some inhibition of MAXF401 tumor growth was observed, but was not significant. In the HT-29 model, erlotinib showed less marked but statistically significant antitumor activity. On day 15, mean tumor-growth inhibition in HT-29, LoVo, KPL-4, MAXF401, and A-431 models was 46, 74, 71, 20, and 85%, respectively. Evaluation of erlotinib/capecitabine combination therapy, at sub-optimal doses, in the three erlotinib-sensitive tumor models LoVo, KPL-4 and A-431, demonstrated at least additive activity with the combination compared with the single agents. In the A-431 and LoVo models, the combination of agents had greater antitumor activity than the single agent capecitabine alone at the MTD. Erlotinib in combination with capecitabine was not associated with significantly increased toxicity compared with single-agent therapy. Erlotinib 100 mg/kg/day induced significant upregulation of TP and DPD in the LoVo model, a significant upregulation of TP in the HT-29, MAXF401 and A-431 models, but had no obvious effect on TP and DPD levels in the KPL-4 model. In the A-431 model, selective upregulation of TP by erlotinib 100 mg/kg resulted in an increased TP:DPD ratio. In the LoVo model, immunohistochemistry revealed marked upregulation of TP (but not DPD by erlotinib). Conclusions: Erlotinib inhibits tumor growth in a range of human tumor xenograft models, including breast and colorectal cancer (CRC). Erlotinib and capecitabine demonstrated at least additive activity in LoVo, KPL-4 and A-431 tumor models. The antitumor activity of the combination was greater than that of capecitabine alone at the MTD. Erlotinib treatment did affect the TP in the CRC tumor models as confirmed immunohistochemically. The findings of this study support clinical evaluation of erlotinib, both as a single agent and in combination with capecitabine, for the treatment of CRC and breast cancer.
