Tarceva - Indicações Tarceva (cloridrato de erlotinibe) está indicado para o tratamento de pacientes com câncer de pulmão de não-pequenas células (CPNPC), localmente avançado ou metastático (estadios IIIb e IV), após a falha de pelo menos um esquema quimioterápico prévio.
This phase 1 trial (MSSM 06-0509; National Clinical Trials identifier NCT00970502) was approved by the Mount Sinai School of Medicine institutional review board, and all patients signed informed consent. The primary endpoints were to describe the dose-limiting toxicity (DLT) of the regimen and to define a recommended phase 2 dose of erlotinib, celecoxib, and reirradiation. The time to progression was a secondary endpoint. Pretreatment evaluations included medical history, physical examination, routine laboratory studies (complete metabolic profile, complete blood count with differential, and international normalized ratio [INR]). Imaging studies included a computed tomography (CT) scan of the neck and either chest CT or whole-body fluorodeoxyglucose-positron emission tomography (FDG-PET) studies.
¹ Nello studio PA.3. ² Comprese ciglia che crescono all’interno, eccessiva crescita e ispessimento delle ciglia. ³ Inclusi casi fatali, nei pazienti che assumevano Tarceva per il trattamento del NSCLC o di altri tumori solidi in fase avanzata (vedere paragrafo 4.4). Una più alta incidenza è stata osservata in pazienti Giapponesi. 4 Negli studi clinici alcuni casi sono stati associati alla co–somministrazione di warfarin (vedere paragrafo 4.5) e a volte alla co–somministrazione di FANS. 5 Compresi gli incrementi di alanina aminotransferasi (ALT), di aspartato aminotransferasi (AST) e di bilirubina). Questi il più delle volte sono stati di entità lieve o moderata, di natura transitoria o associati a metastasi epatiche. 6 Inclusi casi fatali. La patologia epatica pre–esistente o la co–somministrazione di farmaci epatotossici sono stati considerati fattori confondenti (vedere paragrafo 4.4). 7 Inclusi casi fatali (vedere paragrafo 4.4). Segnalazione delle reazioni avverse sospette La segnalazione delle reazioni avverse sospette che si verificano dopo l’autorizzazione del medicinale è importante, in quanto permette un monitoraggio continuo del rapporto beneficio/rischio del medicinale. Agli operatori sanitari è richiesto di segnalare qualsiasi reazione avversa sospetta tramite il sistema nazionale di segnalazione all’indirizzo www.agenziafarmaco.gov.it/it/responsabili.

butalbital-acetaminophen oral will decrease the level or effect of erlotinib oral by affecting hepatic/intestinal enzyme CYP3A4 metabolism.
The reality is that the clear majority of work in Asian patients has been with Iressa, while the majority of work in Western populations has been with Tarceva. I don’t think we’ve got enough good data yet to make comparisons of the two drugs that really are comparing the same thing in similar populations. I would have no difficulty extrapolating all of the Iressa work to Tarceva, except I’d anticipate more rash and perhaps diarrhea side effects because of the higher effective dosing of EGFR inhibitory activity.
Vermijd zwangerschap terwijl u behandeld wordt met Tarceva. Als u zwanger zou kunnen worden, gebruik dan afdoende anticonceptie tijdens de behandeling en gedurende ten minste 2 weken na inname van de laatste tablet.
Le reazioni avverse osservate più di frequente in pazienti trattati con Tarceva nello studio BO18192 sono state il rash e la diarrea (di qualunque grado, rispettivamente 49% e 20%), per la maggior parte di intensità di grado 1/2 e gestibili senza intervenire. Rash e diarrea di grado 3 si sono verificati rispettivamente nel 6% e nel 2% dei pazienti. Non è stato osservato alcun caso di rash o diarrea di grado 4. Rash e diarrea hanno causato la sospensione di Tarceva rispettivamente nell’1% e in < 1% dei pazienti. Modifiche del dosaggio (interruzioni o riduzioni) a causa del rash e della diarrea si sono rese necessarie rispettivamente nell’8,3% e nel 3% dei pazienti.
La mediana de duración de la respuesta fue de 23.9 semanas: entre 3.71 y 56 semanas. La tasa de respuesta objetiva (respuesta completa y respuesta parcial) fue de 8.6 y 7.9%, respectivamente, en los grupos de TARCEVA ® y placebo. La proporción de pacientes con respuesta completa, respuesta parcial o enfermedad estable fue de 59 y 49.4%, respectivamente, en los grupos de TARCEVA ® y placebo (p = 0.036).

Time on Tarceva when people have Metallic Taste *:
I have “re-challenged” patients with an EGFR inhibitor many months or sometimes years after discontinuing it due to acquired resistance. My experience has been what the very limited data show — rarely you’ll see a significant response, (my best is someone who had progressed on Iressa (gefitinib) after 5.5 years and then went on Tarceva <1 year later, progressing on chemo in between), and it’s not uncommon to see mild improvement or stable disease that lasts for a few months. Overall, it is most likely to be of far less benefit the second time around.
Introduction This page is designed to help you determine the relationship, if any, between TARCEVA and DRUG WITHDRAWAL SYNDROME. In doing so, we compare TARCEVA with other drugs that cause DRUG WITHDRAWAL SYNDROME, to help you evaluate whether or not TARCEVA causes DRUG WITHDRAWAL SYNDROME. Likewise, this page shows the most highly-reported side effects of TARCEVA, so you can see if DRUG WITHDRAWAL SYNDROME ranks among TARCEVA's most well-known side effects.
Targeted treatments like Iressa and Tarceva, take advantage of the biologic differences between cancer cells and healthy cells by "targeting" faulty genes or proteins that contribute to the growth and development of cancer. Many times these drugs are combined with chemotherapy, biologic therapy (immunotherapy), or other targeted treatments.
Erlotinib interactuando con Vacuna antituberculosa
Von Erlotinib profitierten alle Patienten mit einem Hautausschlag jeden Schweregrads unabhängig davon, ob sie zusätzlich Bevacizumab erhalten hatten oder nicht. So lag das mediane Gesamtüberleben der Patienten ohne Hautausschlag bei Behandlung mit Gemcitabin/Erlotinib ± Bevacizumab bei 4,8 Monaten, mit Hautausschlag jeden Schweregrads jedoch bei 8,0 Monaten (HR = 0,54 [0,44-0,65], p < 0,0001). Auch das PFS der Patienten mit Hautausschlag war signifikant länger (2,5 vs. 4,6 Monate, HR = 0,53, p < 0,0001). Da der Hautauschlag bei rund zwei Dritteln der Patienten in der Studie auftrat, dürften auch rund zwei Drittel der Patienten von der Erlotinib-Einnahme profitieren (4).

PURPOSE: This randomized phase II trial is studying how well giving panitumumab together with gemcitabine and erlotinib works compared to giving gemcitabine and erlotinib alone in treating patients with metastatic pancreatic cancer.
Tarceva, an orally available small molecule, has demonstrated potent activity in tumor models and humans. This randomized, open-label phase 2 study of Tarceva alone and of Tarceva plus VELCADE is designed primarily to determine the objective tumor response rates to these treatments in patients with Stage IIIB or Stage IV non-small cell lung cancer (NSCLC) that is refractory to or has relapsed after front-line chemotherapy.

Common Questions and Answers about Avastin and tarceva for lung cancer
According to the company release, Tarceva is a novel therapy for patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) after failure of at least one prior chemotherapy regimen. It is an oral tablet taken once a day and has the potential to treat many types of solid tumours. Tarceva has been approved in the US since November 2004 and in the European Union since September 2005. In India, it will cost around Rs 3,30000 for a 3-month treatment.
Cases of interstitial lung disease (ILD)-like events, including fatalities, have been reported uncommonly in patients receiving Tarceva for treatment of non-small cell lung cancer (NSCLC), pancreatic cancer or other advanced solid tumours. In the pivotal study BR.21 in NSCLC, the incidence of ILD (0.8%) was the same in both the placebo and Tarceva groups. In a meta-analysis of NSCLC randomized controlled clinical trials (excluding phase I and single-arm phase II studies due to lack of control groups), the incidence of ILD-like events was 0.9% on Tarceva compared to 0.4% in patients in the control arms. In the pancreatic cancer study in combination with gemcitabine, the incidence of ILD-like events was 2.5% in the Tarceva plus gemcitabine group versus 0.4% in the placebo plus gemcitabine treated group. Reported diagnoses in patients suspected of having ILD-like events included pneumonitis, radiation pneumonitis, hypersensitivity pneumonitis, interstitial pneumonia, interstitial lung disease, obliterative bronchiolitis, pulmonary fibrosis, Acute Respiratory Distress Syndrome (ARDS), alveolitis, and lung infiltration. Symptoms started from a few days to several months after initiating Tarceva therapy. Confounding or contributing factors such as concomitant or prior chemotherapy, prior radiotherapy, pre-existing parenchymal lung disease, metastatic lung disease, or pulmonary infections were frequent. A higher incidence of ILD (approximately 5% with a mortality rate of 1.5%) is seen among patients in studies conducted in Japan.

ARCHER 1050 is an ongoing multicenter, randomized, open-label, Phase III study comparing dacomitinib to gefitinib in treatment-naïve advanced EGFR -mutant NSCLC patients harboring the common-activation EGFR mutations (exon 19 deletions and L858R substitution). The presence of T790M is allowed as long as one of the two common EGFR mutations is also present. The primary end point is PFS, and randomization is one to one. This trial is being conducted only in Asia (People’s Republic of China, Japan, South Korea, Hong Kong) and Europe (Spain, Italy, Poland), and not in North America. The goal of the trial is to show >50% improvement in median PFS in dacomitinib over gefitinib, with an estimated median PFS of erlotinib of 9.5 months and projected median PFS of dacomitinib to be at least 14.3 months. Stratifications are by type of EGFR mutation and ethnicity. 29 The trial schema are represented in Figure 1 .

This analysis is the first to assess the cost-effectiveness of erlotinib as first-line maintenance treatment in patients with stable EGFR wild-type metastatic NSCLC. The results of the modeled analyses demonstrate an incremental costs per life year gained ranging between €20,711 and €25,124 comparing first-line maintenance erlotinib with best supportive care in five European countries (UK, Germany, France, Spain and Italy), and thus well within a range generally considered as cost-effective. Deterministic and probabilistic sensitivity analyses confirmed these findings, indicating that erlotinib first-line maintenance in stable EGFR wild-type metastatic NSCLC translates into improved overall survival and cost-effectiveness across jurisdictions in Europe. These analyses are based on empiric progression-free and overall survival data from the SATURN trial, and several parametric survival models were tested to identify the model with the best fit to the data.

The use of erlotinib as a first-line therapy, in combination with chemotherapy, was tested in two randomized phase 3 studies, TALENT and TRIBUTE. 21. 22 TRIBUTE, a phase 3 trial, evaluated the addition of erlotinib to carboplatin and paclitaxel (Paraplatin and Taxol, Bristol-Myers Squibb) as a first-line therapy for patients with advanced NSCLC who did not meet the primary endpoint of improving overall survival. TALENT (Tarceva Lung Cancer Investigation) was designed to evaluate cisplatin (Platinol, Bristol-Myers Squibb) and gemcitabine (Gemzar) with concurrent and continued erlotinib therapy compared with placebo.
