A case of a woman with lung adenocarcinoma in which fifteen-month disease control was achieved with second-line erlotinib treatment is presented. Five months after treatment beginning, isolated grade 3 hyperbilirubinemia occurred and daily dose was reduced to 100 mg. Comments on erlotinib hepatic toxicity and the pharmacologic interactions on erlotinib metabolism are given.
CIPLA also sought revocation of the suit patent for violation of Section 8 of the Patents Act and contented that if Polymorph B of Erlotinib Hydrochloride is presumed to have been covered in the suit patent, this would imply Polymorph B of Erlotinib Hydrochloride to be same and substantially the same as the suit patent. Roche was then under an obligation to have disclosed before the patent office while prosecuting its application resulting in IN `774 that it had filed an application for grant of patent for Polymorph B of Erlotinib Hydrochloride resulting in US `221 which fact was not disclosed.

Biomarker Analyses of Clinical Outcomes in Patients with Advanced Hepatocellular Carcinoma Treated with Sorafenib with or without Erlotinib in the SEARCH Trial Clin. Cancer Res. October 1, 2016; 22(19): 4870 - 4879. [Abstract] [Full Text] [PDF]
The discovery of a link between activating EGFR mutations in clinical NSCLC and response to the EGFR TKIs gefitinib and erlotinib 2. 3 and 4 was a milestone in the field of personalized cancer therapy. However, resistance emerges in all patients who initially responded to these agents highlighting the importance of seeking novel therapies for lung cancers dependent on mutant EGFR activity. Knowledge of the cell biology and drug sensitivity of cells expressing drug resistance mutations must be considered in the design of novel agents to prevent or overcome acquired drug resistance in the clinic. The inducible expression of EGFR T790M in HCC827 cells described here represents a robust, isogenic system to study the properties conferred by this important drug resistance mutant to a clinically relevant cell line.

Progression on Tarceva, considering options
Anti-EGFR (epidermal growth factor receptor) therapies, including tyrosine kinase inhibitors (TKIs) and monoclonal antibodies, demonstrate activity in a variety of tumor types. While both inhibit the EGFR pathway, they act via different mechanisms. Monoclonal antibodies bind to the extracellular domain of EGFR, preventing ligand binding and interrupting the signaling cascade. Tyrosine kinase inhibitors bind to the intracellular domain of EGFR and inhibit the downstream effects of EGFR ligand binding. Both categories of agents have been evaluated in a variety of clinical settings and tumor types, including colorectal cancer, non-small-cell lung cancer (NSCLC), and squamous cell carcinoma of the head and neck (SCCHN). Phase II/III trials in patients with previously treated or untreated metastatic colorectal cancer, including those with documented refractory disease, demonstrate activity of the monoclonal antibody cetuximab (Erbitux) as a single agent or in combination with both irinotecan (Camptosar)- and oxaliplatin (Eloxatin)-based chemotherapy. Activity of cetuximab added to chemotherapy in patients who previously progressed on the same regimen suggests an ability to overcome chemotherapy resistance in some patients. In NSCLC, phase II trials of the TKI gefitinib (Iressa) plus combination chemotherapy showed impressive activity with considerable toxicity. Large, randomized, phase II trials (IDEAL 1 and 2) reported modest activity of gefitinib in NSCLC; however, phase III trials (INTACT 1 and 2) failed to demonstrate a benefit to adding gefitinib to chemotherapy. A similar trend was noted in trials of erlotinib (Tarceva) (TALENT and TRIBUTE). Phase II/III trials have shown promising activity of cetuximab in SCCHN, generating significantly improved survival in combination with radiotherapy over radiotherapy alone in locally advanced disease and significantly improved response rates in combination with chemotherapy over chemotherapy alone in recurrent/metastatic disease, with little enhancement of toxicity profiles. Limited clinical experience with TKIs in SCCHN suggests similar degrees of single-agent activity and dermatologic toxicities. Levels of EGFR expression and the presence of EGFR mutations correlate with responsiveness to TKI therapy, while it remains unclear whether a relationship exists between level of EGFR expression and cetuximab efficacy in colorectal cancer. Anti-EGFR therapies are good candidates for combination with other treatment modalities, including chemotherapy and radiotherapy, due to their tolerable safety profile and nonoverlapping toxicities. In addition, these agents represent important treatment options in patients ineligible for chemotherapy due to refractory or resistant disease. Ongoing trials continue to investigate both the monoclonal antibodies and TKIs in various treatment settings.

Buna Mircea, Mamei mele tocmai i-am facut in urma cu o luna pomenirea de un an. Dupa cate am citit cat era mama bolnava, cancerul de pancreas e cel mai "parshiv". mai rau decat cel la plamani. tu esti inca tanar, trebuie sa speri, numai sa iti ajute Dumnezeu sa fii pe mana unui medic curant care sa stie cum sa iti administreze TARCEVA. eu am citit ca acest medicament trebuie combinat cu gemcitabina. ceea ce mamai mele nu i s-a intamplat, pe motiv ca nu i-ar fi rezistat organismul. in plus, se spune ca fiecare organism raspunde in felul lui, probabil ca mama mea a fost un nonresponder. In plus,si varsta isi spune cuvantul. si, repet, tu esti tanar inca, poti spera in rezultate bune. Daca ai sa citesti prospectul medicamentului, in el se spune ca actioneaza in sensul "imbunatatirii calitatii vietii", nu al vindecarii. Numai bine iti doresc!

erlotinib 150 mg taken orally daily until disease progression
Based on different HRs for taking on second-line treatment for the two chemotherapy arms, the model uses different transition probabilities for progression through the lines of therapy to death. As a result, one chemotherapy sequence has a modelled additional survival benefit compared with the other. The PBAC considered that, again, no evidence was provided to support a survival advantage from more and quicker uptake of second-line erlotinib in patients who are treated with first-line chemotherapy.

A Phase II-R and a Phase III Trial Evaluating Both Erlotinib (Ph II-R) and Chemoradiation (Ph III) as Adjuvant Treatment for Patients With Resected Head of Pancreas Adenocarcinoma
The pharmacodynamics of gefitinib were studied in two phase I trials in which the effects of gefitinib on EGFR tyrosine kinase activity in cancer patients were evaluated [27 ]. The pharmacodynamics of erlotinib were studied in the phase II trial in patients with advanced NSCLC [21. 22 ]. Skin expresses EGFR tyrosine kinase, and the results of the phase I and phase II trials showed that it can serve as a surrogate tissue for detecting EGFR tyrosine blockade. Cutaneous rash can be used as a surrogate marker of clinical benefit for both erlotinib and gefitinib [21. 22. 28 ]. Besides skin, it was shown that high levels of EGFR expression could also be detected in human hair follicles [29 ]. The use of hair is minimally invasive, in comparison with skin biopsies, and offers the possibility of being used as a surrogate tissue to quantitate the pharmacodynamics of EGFR inhibitors. The results of the phase I and phase II trials also showed that, besides EGFR, downstream molecules of the EGFR signaling pathway also can serve as markers. For example, after treatment with gefitinib, expression of mitogen-activated protein kinase (MAPK) was also reduced [30 ]. Recently, the erlotinib marker identification program was designed to identify and investigate predictive or surrogate markers other than rash. A large number of clinical samples will be analyzed from patients enrolled in the TALENT, TRIBUTE, and BR.21 trials. The identification of predictive or surrogate markers of response would permit selection of patients most likely to respond to such treatment. Markers could consist of tumor characteristics, such as those of the receptor or downstream signaling molecules and determinants of resistance [31 ]. Recently, it was shown that an increased EGFR gene copy number, based on fluorescence in situ hybridization analysis, could be used as a predictive marker for sensitivity to gefitinib and erlotinib [32 ]. Another study revealed that mutations in the downstream GTPase K-Ras were associated with a lack of sensitivity to gefitinib and erlotinib [33 ]. Tumors with K- ras exon 2 mutations were associated with response rates of 0% to both gefitinib and erlotinib. If confirmed in other studies, mutations in K- ras could be used as predictive markers of response to gefitinib and erlotinib.

The preferred method of differentiating erlotinib hydrochloride crystalline polymorph form A from crystalline polymorph B is X-ray powder diffraction (PX- RD). The PX-RD pattern of erlotinib hydrochloride crystalline polymorph form A substantially free of polymorph form B, as illustrated in Figure 5, contains no peak having 2Θ angle position at about 6.26 + 0.2 degrees which peak is the characteristic peak of polymorph B. X-ray powder diffraction provides a convenient and practical means for quantitative determination of the relative amounts of crystalline polymorph A and/or crystalline polymorph B forms in a solid mixture. X-ray powder diffraction is adaptable to quantitative applications because the intensities of the diffraction peaks of a given compound in a mixture are proportional to the fraction of the corresponding powder in the mixture. Therefore, the percent composition of crystalline polymorph A or crystalline polymorph B form of erlotinib hydrochloride in an unknown composition can be determined by using standard calibration curve, which can be constructed by spiking known amount of pure crystalline polymorph B into crystalline polymorph A of erlotinib hydrochloride to determine the percent ratio of crystalline polymorph B. For example, five or more artificial mixtures of crystalline polymorph B of erlotinib hydrochloride, at different amounts, may be prepared. Such mixtures may contain, 1%, 3%, 5%, 7%, and 10% of crystalline polymorph B of erlotinib hydrochloride. Preferably, the measurements are made on solid powder erlotinib hydrochloride. This is done by comparing the relative intensities of the peaks from the diffraction pattern of the unknown solid powder composition with a calibration curve derived from the X-ray diffraction patterns of pure known samples.
Development and validation of RP-HPLC method for the estimation of Erlotinib in pharmaceutical formulation
The recommended daily dose of erlotinib for NSCLC is 150 mg taken orally at least one hour before or two hours after the ingestion of food. Treatment should continue until disease progression or unacceptable toxicity.
During the past decade, numerous radiolabeled EGFR-targeted agents, namely antibodies and TKIs, have been investigated as probes for visualizing and quantifying EGFR expression in tumors using nuclear imaging modalities, such as single photon emission computed tomography (SPECT) and PET [ 16 - 29 ]. Notably, both erlotinib and gefitinib have been labeled with positron-emitting isotopes and evaluated in preclinical animal models. Reports on 11 C- and 18 F-labeled gefitinib imaging in tumor-bearing mice indicated that [ 11 C]gefitinib has more potential than its fluorine-18-labeled congener, although to date, neither has progressed into clinical trials [ 26. 29 ]. Conversely, reports on [ 11 C]erlotinib have revealed its added value in imaging EGFR mutant-positive tumors not only in mice [ 19. 24 ], but also in humans [ 18. 20. 28 ]. Hitherto, elevated tumor uptake of [ 11 C]erlotinib has been demonstrated only in tumors harboring EGFR exon 19 deletions compared to tumors without activating EGFR mutations [ 18. 19. 24. 28 ]. However, the extent to which [ 11 C]erlotinib PET could identify NSCLC tumors that harbor other commonly detected TK mutations, such as the activating exon 21 L858R point mutation and the T790M gate-keeper mutation, which confers resistance to TKI therapy, has not been reported.
