A Randomized, Placebo-Controlled Phase II Clinical Trial of Combination Erlotinib (Tarceva) and Celecoxib (Celebrex) Versus Erlotinib (Tarceva)/Placebo in Advanced Non-Small Cell Lung Cancer Patients
The combination of erlotinib and bevacizumab for treating patients with advanced papillary renal cell carcinoma shows excellent response rates with tolerable side effects. This is particularly true of patients with hereditary leiomyomatosis and renal cell cancer.
Tarceva is OSI’s only product but sales last year reached about $1.2 billion. The drug has been approved to treat various cancers including non-small cell lung cancer (second line treatment) and first-line advanced pancreatic cancer. OSI has been trying to garner approval for Tarceva to treat other types of cancer in recent years. While sales of Tarceva have been growing annually, OSI’s new drug pipeline has been relatively thin.

The present systematic review has some limitations. First, data could not be obtained from two included studies despite our contact with the primary investigators [17. 33 ]. Second, some trials such as TRIBUTE [16 ] enrolled 934 Caucasian patients and 154 others, while FASTACT [14 ] enrolled 145 Asian patients and 6 Caucasian patients. Due to limited data, we were unable to perform a pooled analysis according to ethnicity. To explore a high heterogeneity level in total PFS, we conducted subgroup analysis according to dominant ethnicity. What is more, given the probable bias due to the overlap of never smokers and EGFR mutants, data on never smokers are likely influenced by higher rate of EGFR mutants, since only 601 patients had EGFR status evaluated. We conclude that the combination of chemotherapy and erlotinib is a viable treatment option for patients with EGFR mutation. However, for patients with EGFR mutation-positive NSCLC, the current standard care is EGFR TKI alone. OPTIMAL study showed that compared with chemotherapy, erlotinib demonstrated a significant benefit in patients with advanced EGFR mutation-positive NSCLC, and median PFS was 13.1 months for erlotinib-treated patients versus 4.6 months for patients receiving chemotherapy [31 ]. In FASTACT-2, patients with EGFR mutation derived benefit from the combination treatment, and median PFS was 16.8 months [11 ]. We didn't address whether a combination treatment was better than erlotinib alone for patients with EGFR mutation-positive NSCLC. A head-to-head study is needed to answer this question. In this systematic review, we analyzed the efficacy of different schedules of erlotinib in combination with chemotherapy, and led to a conclusion that the intercalated schedule showed an improvement in PFS and OS, while the continuous schedule did not.

Before taking Erlotinib tablets, Discuss with your doctor if you have, or have ever had. Lung disease or infection. Kidney disease. Allergies to medicines. Heart problems etc.

Before starting Erlotinib treatment, make sure you tell your doctor about any other medications you are taking (including prescription, over-the-counter, vitamins, herbal remedies, etc.). It is important your oncologist is aware of all medications. Do not take aspirin, or products containing aspirin unless your doctor specifically permits this.

Severe: A severe Tarceva rash is often generalized (covering the face, upper chest, and upper back) and is usually associated with severe symptoms of itching and tenderness. It significantly impacts quality of life. There can be ulceration (open sores) weeping (drainage) and signs of a secondary skin infection such as redness, yellow or green discharge, and fever.

Anticoagulants Interaction with coumarin-derived anticoagulants, including warfarin, leading to increased International Normalized Ratio (INR) and bleeding adverse reactions, which in some cases were fatal, have been reported in patients receiving Tarceva. Regularly monitor prothrombin time or INR in patients taking coumarin-derived anticoagulants. Dose modifications of Tarceva are not recommended [see Warnings and Precautions (5.10 ) and Adverse Reactions (6.1 )] .

Characterization of H441 orthotopic tumor stroma after anti-VEGF therapy and dual EGFR/VEGFR2 inhibition. We next sought to more completely characterize the vasculature and stroma of BV-resistant H441 tumors. We found a significant decrease in MVD after 2 weeks of BV treatment compared with vehicle controls ( P = 0.0008; Figure 7 E). Consistent with the revascularization observed in the subcutaneous models, tumors resistant to BV or dual VEGFR/EGFR inhibition showed significantly increased MVD compared with BV-sensitive tumors ( P = 0.045; Figure 7 E). Interestingly, in the erlotinib-resistant group, no revascularization was observed; in fact, MVD was significantly lower than in BV-resistant tumors ( P = 0.034; Figure 7 E). These findings indicate that VEGF inhibitor resistance is associated with revascularization in H441 orthotopic tumors.
All patients will receive erlotinib at 150mg orally daily along with doses of ruxolitinib orally twice daily.

In dose level 2, patients will receive erlotinib 150mg orally daily and ruxolitinib 15mg orally twice daily. In dose level 3, patients will receive erlotinib 150mg orally daily and ruxolitinib 20mg orally twice daily.

Analysts said Tarceva could bring the manufacturers and partners more than $1 billion a year in global sales. On Friday, OSI shares rose $5.25 to $40.65, according to newsdayreported.
Erlotinib (Tarceva) is a small-molecule, orally dosed, anti-cancer drug that inhibits the epidermal growth factor receptor. Randomized, controlled clinical studies have demonstrated that erlotinib significantly improved survival in patients with previously treated non–small-cell lung cancer and, in combination with chemotherapy, in patients with untreated pancreatic cancer. In this article, we describe the clinical evidence and value of erlotinib as a therapy for non–small-cell lung cancer and pancreatic cancer and discuss ongoing clinical studies to optimize its use in various settings and to identify appropriate patient populations.
CH5164840 treatment suppressed erlotinib-induced Stat3 signaling in NCI-H292 cells. (a) NCI-H292 cells were treated with 0.2 μM erlotinib and/or 0.5 μM CH5164840 for 48 h, lysed and analyzed using western blotting. (b) NCI-H292 cells were treated with the indicated concentration of erlotinib for 24 h and analyzed for Stat3 and phospho-Stat3 protein. (c) NCI-H292 cells were treated with 0.2 μM erlotinib and/or 0.5 μM CH5164840 for 48 h and cytosol and nuclear fractions were analyzed using western blotting. Histone H1 indicates loading control for nuclear fraction. (d) NCI-H292 cells were transfected with 10 nM Stat3, JAK1, JAK2, Tyk2 or control siRNA. At 24 h post-transfection, cells were treated with 0.2 μM erlotinib and cultured for 24 h, lysed and analyzed using western blotting. (e) NCI-H292 cells were transfected with 10 nM Stat3 siRNA, JAK1 siRNA or control siRNA and treated with DMSO or 0.2 μM erlotinib. At 96 h post-transfection, cell viability was determined by CellTiter-Glo. Data are shown as mean ± SD ( n = 3).

Next, we applied bevacizumab alone or plus erlotinib to the NSCLC cells in vitro. As reported previously [21 ], bevacizumab alone did not inhibit the growth of the tested NSCLC cells in vitro (Fig. 1 c). Growth inhibition with bevacizumab (10 ng/mL) plus erlotinib (1 µmol/L) was similar to that with erlotinib alone (1 µmol/L; Fig. 1 d) in the six NSCLC cells ( P > 0.05).
