In the DLT evaluation period, there was one grade III neutropenia in the first cohort. At this level, three subjects subsequently withdrew consents to continue study prior to completing the DLT evaluation period. One subject was unwilling to continue follow-up due to distance, and two other subjects had grade II but intolerable side effects did not want to continue with the trial. The remaining two subjects did not experience any DLT. Upon dose escalation to level 2, two subjects developed DLTs with prolonged grade III mucositis (1) and grade III rash (1), despite maximal medical managements. At this point, the protocol was amended to titrate up sirolimus instead of erlotinib (dose 2b). However, two more subjects had DLTs at this level with one grade III hypophosphatemia and one Serious Adverse Events with hospitalization for altered mental status, without tumor progression, in the DLT evaluation period. At this level, one subject also withdrew consent prior to completing the first cycle. As a result, dose level 1 was expanded to another three patients (with two subjects withdrawing consent before evaluable for DLTs) and had no further DLTs. Therefore, the MTD was determined to be dose level 1 (Table  2 ).
Two phase I clinical trials that have investigated the safety and efficacy of the erlotinib-pemetrexed combination have been reported. In the first study by Ranson et al. [ 17 ], where both agents were started on the same day, DLTs were not experienced at doses of up to 150 mg/day of erlotinib plus 600 mg/m 2 of pemetrexed; the RD was determined as being equal to each of the licensed single-agent doses (150 mg daily and 500 mg/m 2 every 21 days, respectively). In the second study by Davies et al. [ 18 ], the RD and administration schedule was fixed at a dose of 250 mg from day 2 to 16 for erlotinib and 500 mg/m 2 on day 1 for pemetrexed every 21 days. We used the same RD as in the first trial with an identical administration schedule to that used in the second trial, and have now moved to an ongoing phase II trial.
Bevacizumab/Erlotinib Combo Approved in Europe for NSCLC
Background: First-line erlotinib (an EGFR tyrosine-kinase inhibitor) significantly increased progression-free survival (PFS) vs chemotherapy in phase III trials of pts with EGFR mutation-positive NSCLC. Discontinuation of erlotinib on RECIST disease progression (PD) may lead to rapid disease flare-up; continued erlotinib beyond RECIST PD may extend clinical benefit by slowing progression of this life-threatening disease. We describe ASPIRATION, a large, Asian, multicenter, single-arm, open-label, phase II trial (NCT01310036), which will increase understanding of first-line erlotinib and erlotinib continuation beyond RECIST PD in pts with EGFR -mutated NSCLC. Methods: Pts (n=204) ≥18 yrs with stage IV/recurrent NSCLC, ≥1 measurable lesion (≥10mm), ECOG performance status (PS) 0-2 and positive EGFR mutation status established by local pathology laboratory (that underwent voluntarily QA/QC) are eligible. All pts receive erlotinib 150mg/day. Tumor response is evaluated using RECIST (v1.1). The primary endpoint is PFS. At investigator's discretion, pts may continue on erlotinib beyond RECIST PD, e.g. if they have slow PD (>6 months of partial response/stable disease), asymptomatic minimal PD, or new brain metastasis controlled locally. Pts should not continue erlotinib if they have extracranial PD with symptoms; rapid PD and/or worsening of PS; or life-threatening complications. Pts continuing erlotinib who present with second RECIST PD will discontinue. Secondary endpoints include objective response rate, disease control rate, overall survival, and safety. For the exploratory biomarker study, pre-treatment tumor tissue blocks are collected; remaining tissue (after EGFR mutation testing for eligibility) will be analyzed centrally to study the association of biomarkers and clinical outcomes. Pre-treatment and post-treatment plasma and serum samples will be obtained at various time points for biomarker assays, including EGFR mutations and other candidate NSCLC biomarkers. Recruitment began in Apr 2011; the estimated final data collection for the primary endpoint is Dec 2014.

Due to nicotine addiction, only a few percent of smokers quit successfully each year [15]. NSCLC patients who continue to smoke, or return to smoking, or have an second-hand smoke exposure, might experience tumor progression, resistance to therapy, higher recurrence rate after successful treatment and other risks of mortality [5]. [6]. [7]. [8] and [9]. The activation of nAChR induced by nicotine might be involved in those procedures [12]. [13]. [14]. [15]. [16]. [17]. [18]. [19]. [20]. [21] and [22]. It has been demonstrated that EGFR activity contributes to the growth and progression of NSCLC, and EGFR mutation status is one of important factors associated with response to EGFR-TKIs such as erlotinib [33]. Although EGFR mutations are less prevalent in NSCLC patients with smoking history, several studies suggest the existence of cooperation between nAChR and EGFR in cancer progression [17]. [21] and [24] .
The FDA has approved three drugs for second-line treatment of NSCLC, one of which is Tarceva. The other two are Taxotere (docetaxel) and Alimta (pemetrexed), either of which are usually appropriate choices. There are also other drugs which, though they have not been specifically approved in the second-line setting, are known to be active against NSCLC. These include gemcitabine and navelbine. There are also clinical trials of new drugs, some of which seek to overcome resistance to an EGFR TKI such as Tarceva.

I had some initial problems communicating with MD Anderson regarding the availability and need for various prophylactics as the standard answer from nursing staff was tylenol and otc hydroccortizone. Dr. Kim was with you in Korea at the time and I was in great pain so got treatment at local oncologist and local GI who set me up with antibiotics and prescription hydrocortisone and some hydrocodone for the pain. After 13 days I was advised to stop the erlotinib by Dr Kim.
Erlotinib is not recommended for people who have not responded to two prior chemotherapy regimens, including docetaxel or for those with locally advanced or metastatic NSCLC who cannot take docetaxel and who have not responded to one chemotherapy regimen.

Common Side Effects With Tarceva
Potent inducers of CYP3A4 may reduce the efficacy of erlotinib whereas potent inhibitors of CYP3A4 may lead to increased toxicity. Concomitant treatment with these types of agents should be avoided (see section 4.5).
We are 28 Months down the road and have been through Tarceva. carboplatin/paclitaxel/avastin. a phase II trial and are setting off on the next stage. I think there are too many variables to give one answer, but the thing that has made a difference is good morale and a willingness to wage absolute war with the disease. We are not done yet and are going tomorrow to choose from an array of options, some of whom were not available 6 months ago.

There have been a few large trials that directly tested the combination of Tarceva/Avastin vs. Tarceva alone — one as second line treatment (called BeTa). and one as maintenance therapy (called ATLAS). These have failed to demonstrate a significant benefit for the combination, but they were in molecularly unselected patients . meaning that they were a broad population and not just patients with a specific molecular feature like an activating EGFR mutation. However, both of these trials provided hints that the combination appeared to be especially effective for specific patients, most likely those with an EGFR mutation. For instance, the BeTa trial showed that two particular clinically defined subsets demonstrated an overwhelming benefit for the combination over Tarceva alone — Asian or Pacific Islander, and never-smokers. Of course, these are also two subgroups known to be highly enriched for having an activating an EGFR mutation. The subgroup analysis also showed that the small subgroup with an EGFR mutation also did far better with the combination, corroborating our presumption about why the Asian/Pacific Islander and never-smoker groups did so well.
In the first study, in lung cancer patients with EGFR activating mutations, patients taking Tarceva as initial treatment survived without their disease getting worse for an average of 9.7 months compared with 5.2 months for those receiving other chemotherapy medicines.

Hello. I am a 65 y/o E Indian non smoking female dz 4/09 w met EGFR 19+ adenoca of the lung. I have received 2 courses of systemic chemotherapy for dz progression during the last 2 years and 2 courses of palliative radiotherapy, all the while maintained on Tarceva. My most recent PETCT in April shows innumerable bl lung nodules, all sub cm in size. I have been seen at both USC (no options there) and then UCLA. I am apparently a candidate for the Clovis drug CO-1686, the Merck PD-1 antibody, and a c-MET inhibitor. I had a rebx in Feb 2013 which again showed the EGFR 19 mutation as well as a new mutation T790M and high over expression of cmet.
Insuficiencia renal: La seguridad y eficacia de erlotinib no ha sido estudiada en pacientes con insuficiencia renal (concentración sérica de creatinina > 1,5 veces el límite superior normal). Sin embargo no parece necesario un reajuste de la dosis en pacientes con insuficiencia renal media o moderada. No se recomienda el uso de erlotinib en pacientes con insuficiencia renal grave.

New data presented at ASCO 2008 from TRUST(1), the largest non-small cell lung cancer (NSCLC) Phase IV trial ever conducted, show that a broad range of NSCLC patients treated with Tarceva (erlotinib) experience clinical benefits including longer survival, better quality of life, control of disease symptoms and control of cancer progression. NSCLC is the most common and deadly form of lung cancer suffered by over one million people worldwide(2).
Let your doctor know about the lumps you’re experiencing. You might want to return to tarceva until you have another direction ready.
Roche and the Spanish Lung Cancer Group (SLCG) will collaborate on the first Phase III trial to investigate Tarceva in lung cancer patients with genetic mutations in their epidermal growth factor receptor (EGFR). Over activity of EGFR is associated with the growth and development of lung cancer.

Clinical benefit has been demonstrated in patients with head and neck tumours receiving an anti-epidermal growth factor receptor (EGFR) agent in combination with radiotherapy (RT). Recent preclinical and clinical studies suggest beneficial effects from combining anti-angiogenic drugs with RT. To investigate the effect of combining these approaches, we evaluated in vivo the anti-tumour efficacy of the anti-angiogenic compound bevacizumab, a highly specific monoclonal antibody directed against the vascular endothelial growth factor (VEGF), erlotinib, an EGFR tyrosine kinase inhibitor, and irradiation given alone and in combination. Investigations were performed using a VEGF-secreting human head and neck tumour cell line, CAL33, with a high EGFR content, injected as orthotopic xenografts into the mouth floor of nude mice. Three days after tumour cell injection, bevacizumab (5   mg   kg −1. 5 days a week, i.p.), erlotinib (100   mg   kg −1. 5 days a week, orally) and irradiation (6   Gy, 3 days a week) were administered alone and in combination for 10 days. As compared with the control, concomitant administration of drugs produced a marked and significant supra-additive decrease in tumour mass; the addition of irradiation almost completely abolished tumour growth. The drug association markedly reduced the number of metastatic nodes and the triple combination significantly reduced the total number of pathologically positive lymph nodes as compared with controls. The RT-induced proliferation, reflected by Ki67 labelling, was reduced to control level with the triple combination. Radiotherapy induced a strong and very significant increase in tumour angiogenesis, which was no longer observed when combined with erlotinib and bevacizumab. The efficacy of the combination of bevacizumab + erlotinib and RT may be of clinical importance in the management of head and neck cancer patients.
