Anti-epidermal growth factor receptor antibody C225 inhibits angiogenesis in human transitional cell carcinoma growing orthotopically in nude mice. (1/5340)

Epidermal growth factor receptor (EGFR) regulates the growth and progression of human transitional cell carcinoma (TCC) of the bladder. We have shown that therapy targeting EGFR inhibited the growth of human TCC established orthotopically in nude mice. The purpose of this study was to evaluate whether EGFR-directed therapy affects angiogenesis associated with the growth and metastasis of human TCC. We determined the cytostatic effect and the effect on production of angiogenic factors after in vitro treatment of the human TCC cell line 253J B-V with MAb C225, a chimerized monoclonal anti-EGFR antibody. The 253J B-V cells were implanted orthotopically into athymic nude mice, and established tumors (4 weeks) were treated with i.p. MAb C225. Expression of the angiogenic factors vascular endothelial growth factor (VEGF), interleukin-8 (IL-8), and basic fibroblast growth factor (bFGF) was evaluated by immunohistochemistry and in situ mRNA hybridization analyses and correlated with microvessel density evaluated after immunohistochemical staining with anti-CD31. In vitro treatment with MAb C225 inhibited mRNA and protein production of VEGF, IL-8, and bFGF by 253J B-V cells in a dose-dependent manner. MAb C225 therapy of nude mice with established TCCs growing orthotopically resulted in inhibition of growth and metastasis compared with controls (P <0.0005). VEGF, IL-8, and bFGF expression was significantly lower in treated tumors than in controls. The down-regulation of these angiogenic factors preceded the involution of blood vessels. These studies indicate that therapy with anti-EGFR MAb C225 has a significant antitumor effect mediated, in part, by inhibition of angiogenesis.  (+info)

A sialoglycoprotein, gp20, of the human capacitated sperm surface is a homologue of the leukocyte CD52 antigen: analysis of the effect of anti-CD52 monoclonal antibody (CAMPATH-1) on capacitated spermatozoa. (2/5340)

In this study we performed N-terminal sequence analysis of gp20, a 20 kDa sialoglycoprotein on the human sperm surface previously identified by radiolabelling of the sialic acid residues of sperm surface. We found 100% identity with the N-terminus of CD52, an antigen expressed on almost all human leukocytes. We also show that, like CD52, gp20 behaves as a glycosylphosphatidylinositol (GPI)-anchored protein and that anti-gp20 antiserum reacts with an antigen on leukocytes of the same molecular weight as CD52. Using CAMPATH-1, the monoclonal antibody against CD52, in fluorescent staining of capacitated spermatozoa, Western blot analysis and the zona-free hamster egg penetration test, we found that the effect of this antibody was different from that of our anti-gp20. Western blot analysis revealed a well-defined 20 kDa band with anti-gp20, whereas a 14-20 kDa band was detected with CAMPATH-1. Anti-gp20 stained the equatorial region of the sperm head, whereas CAMPATH-1 stained the tail in immunofluorescence analysis of capacitated spermatozoa. A dose-dependent inhibitory effect was seen with CAMPATH-1, similar to that previously detected with anti-gp20, in a zona-free hamster egg penetration test. However, with CAMPATH-1 agglutination of motile spermatozoa was detected, and this was not present with anti-gp20. This suggests that the epitopes recognized by the two antibodies are different.  (+info)

Elimination of the immunogenicity of therapeutic antibodies. (3/5340)

The immunogenicity of therapeutic Abs limits their long-term use. The processes of complementarity-determining region grafting, resurfacing, and hyperchimerization diminish mAb immunogenicity by reducing the number of foreign residues. However, this does not prevent anti-idiotypic and anti-allotypic responses following repeated administration of cell-binding Abs. Classical studies have demonstrated that monomeric human IgG is profoundly tolerogenic in a number of species. If cell-binding Abs could be converted into monomeric non-cell-binding tolerogens, then it should be possible to pretolerize patients to the therapeutic cell-binding form. We demonstrate that non-cell-binding minimal mutants of the anti-CD52 Ab CAMPATH-1H lose immunogenicity and can tolerize to the "wild-type" Ab in CD52-expressing transgenic mice. This finding could have utility in the long-term administration of therapeutic proteins to humans.  (+info)

Cooperative inhibitory effect of novel mixed backbone oligonucleotide targeting protein kinase A in combination with docetaxel and anti-epidermal growth factor-receptor antibody on human breast cancer cell growth. (4/5340)

Type I protein kinase A (PKAI) is overexpressed in the majority of human tumors and plays a relevant role in neoplastic transformation, conveying mitogenic signals of different growth factors and oncogenes. Inhibition of PKAI by antisense oligonucleotides targeting its RIalpha regulatory subunit results in cancer cell growth inhibition in vitro and in vivo. We have recently shown that a mixed backbone oligonucleotide targeting RIalpha can cooperatively inhibit human cancer cell growth when combined with selected cytotoxic drugs. In the present study, we have used HYB 165, a novel DNA/RNA hybrid mixed backbone oligonucleotide that exhibits improved pharmacokinetic and bioavailability properties in vivo and is presently undergoing Phase I trials. We have shown that HYB 165 exhibits a dose-dependent inhibitory effect on ZR-75-1 cells and a cooperative activity with docetaxel, a cytotoxic drug active in breast cancer. The antiproliferative activity is accompanied by increased apoptosis, as compared with each single agent. On the basis of our previous demonstration of a structural and functional relation between PKAI and epidermal growth factor receptor, we have performed a double blockade of these pathways using HYB 165 in combination with monoclonal antibody (MAb) C225, an anti-epidermal growth factor receptor chimeric MAb. The two compounds determined a cooperative growth inhibitory effect on ZR-75-1 cells and increased apoptosis. To study whether different biological agents and cytotoxic drugs can interact together, low doses of HYB 165, MAb C225, and docetaxel were combined causing an even greater cooperative effect toward growth inhibition. Finally, we have demonstrated that each single agent is able to induce bcl-2 phosphorylation and that the three agents, used in combination at suboptimal doses, determine a greater degree of bcl-2 phosphorylation and cause apoptosis of the majority of ZR-75-1 cells. These findings provide the basis for a novel strategy of treatment of breast cancer patients because both HYB 165 and MAb C225 are presently under clinical evaluation.  (+info)

Antitumor activity of sequential treatment with topotecan and anti-epidermal growth factor receptor monoclonal antibody C225. (5/5340)

Epidermal growth factor (EGF)-related proteins such as transforming growth factor alpha (TGF-alpha) control cancer cell growth through autocrine and paracrine pathways. Overexpression of TGF-alpha and/or its receptor (EGFR) has been associated with a more aggressive disease and a poor prognosis. The blockade of EGFR activation has been proposed as a target for anticancer therapy. Monoclonal antibody (MAb) C225 is an anti-EGFR humanized chimeric mouse MAb that is presently in Phase II clinical trials in cancer patients. Previous studies have suggested the potentiation of the antitumor activity of certain cytotoxic drugs, such as cisplatin and doxorubicin, in human cancer cell lines by treatment with anti-EGFR antibodies. We have evaluated in human ovarian, breast, and colon cancer cell lines, which express functional EGFR, the antiproliferative activity of MAb C225 in combination with topotecan, a cytotoxic drug that specifically inhibits topoisomerase I and that has shown antitumor activity in these malignancies. A dose-dependent supraadditive increase of growth inhibition in vitro was observed when cancer cells were treated with topotecan and MAb C225 in a sequential schedule. In this respect, the cooperativity quotient, defined as the ratio between the actual growth inhibition obtained by treatment with topotecan followed by MAb C225 and the sum of the growth inhibition achieved by each agent, ranged from 1.2 to 3, depending on drug concentration and cancer cell line. Treatment with MAb C225 also markedly enhanced apoptotic cell death induced by topotecan. For example, in GEO colon cancer cells, 5 nM topotecan, followed by 0.5 microg/ml MAb C225, induced apoptosis in 45% cells as compared with untreated cells (6%) or to 5 nM topotecan-treated cells (22%). Treatment of mice bearing established human GEO colon cancer xenografts with topotecan or with MAb C225 determined a transient inhibition of tumor growth because GEO tumors resumed the growth rate of untreated tumors at the end of the treatment period. In contrast, an almost complete tumor regression was observed in all mice treated with the two agents in combination. This determined a prolonged life span of the mice that was significantly different as compared with controls (P < 0.001), to MAb C225-treated group (P < 0.001), or to the topotecan-treated group (P < 0.001). All mice of the topotecan plus MAb C225 group were the only animals alive 14 weeks after tumor cell injection. Furthermore, 20% of mice in this group were still alive after 19 weeks. The combined treatment with MAb C225 and topotecan was well tolerated by mice with no signs of acute or delayed toxicity. These results provide a rationale for the evaluation of the anticancer activity of the combination of topoisomerase I inhibitors and anti-EGFR blocking MAbs in clinical trials.  (+info)

Epidermal growth factor receptor blockade with C225 modulates proliferation, apoptosis, and radiosensitivity in squamous cell carcinomas of the head and neck. (6/5340)

We examined effects of the anti-epidermal growth factor receptor monoclonal antibody C225 on proliferation, cell cycle phase distribution, apoptosis, and radiosensitivity in squamous cell carcinoma (SCC) cell lines derived from head and neck cancer patients. Exposure to C225 in culture inhibits SCC proliferation in a time-dependent manner, and the degree of growth inhibition, compared to controls, ranges from 20 to 75%. Flow cytometry analysis demonstrates that C225 treatment induces accumulation of cells in G1, which is accompanied by a 2-3-fold decrease in the percentage of cells in S phase. C225 exposure also induces apoptosis in SCC populations, as demonstrated by flow cytometry analysis using dual stainings of merocyanine 540 and Hoechst 33342. Western blot analysis indicates that C225 exposure induces accumulation of hypophosphorylated retinoblastoma protein and increases expression of p27KIP1. An increase in Bax expression and concurrent decrease in Bcl-2 expression are observed when SCC cells are exposed to C225. Examination of C225 effects on radiation response in SCCs demonstrates enhancement in radiosensitivity and amplification of radiation-induced apoptosis. These effects are observed in both single-dose and fractionated radiation experiments. C225 represents a promising growth-inhibitory agent that can influence cellular proliferation, apoptosis, and radiosensitivity in SCCs of the head and neck.  (+info)

Inhibitory effects of combinations of HER-2/neu antibody and chemotherapeutic agents used for treatment of human breast cancers. (8/5340)

Previous studies have demonstrated a synergistic interaction between rhuMAb HER2 and the cytotoxic drug cisplatin in human breast and ovarian cancer cells. To define the nature of the interaction between rhuMAb HER2 and other classes of cytotoxic drugs, we applied multiple drug effect/combination index (CI) isobologram analysis to a variety of chemotherapeutic drug/rhuMAb HER2 combinations in vitro. Synergistic interactions at clinically relevant drug concentrations were observed for rhuMAb HER2 in combination with cisplatin (CI=0.48, P=0.003), thiotepa (CI=0.67, P=0.0008), and etoposide (CI=0.54, P=0.0003). Additive cytotoxic effects were observed with rhuMAb HER2 plus doxorubicin (CI=1.16, P=0.13), paclitaxel (CI=0.91, P=0.21), methotrexate (CI=1.15, P=0.28), and vinblastine (CI=1.09, P=0.26). One drug, 5-fluorouracil, was found to be antagonistic with rhuMAb HER2 in vitro (CI=2.87, P=0.0001). In vivo drug/rhuMAb HER2 studies were conducted with HER-2/neu-transfected, MCF7 human breast cancer xenografts in athymic mice. Combinations of rhuMAb HER2 plus cyclophosphamide, doxorubicin, paclitaxel, methotrexate, etoposide, and vinblastine in vivo resulted in a significant reduction in xenograft volume compared to chemotherapy alone (P<0.05). Xenografts treated with rhuMAb HER2 plus 5-fluorouracil were not significantly different from 5-fluorouracil alone controls consistent with the subadditive effects observed with this combination in vitro. The synergistic interaction of rhuMAb HER2 with alkylating agents, platinum analogs and topoisomerase II inhibitors, as well as the additive interaction with taxanes, anthracyclines and some antimetabolites in HER-2/neu-overexpressing breast cancer cells demonstrates that these are rational combinations to test in human clinical trials.  (+info)

Maintenance therapy is associated with improved survival in non-small cell lung cancer (NSCLC), but few studies have compared active agents in this setting. In a phase III trial (AVAPERL trial) reported in the Journal of Clinical Oncology by Fabrice Barlesi, MD, PhD, of Aix Marseille University-Assistance Publique Hôpitaux de Marseille, and colleagues, patients with advanced nonsquamous NSCLC who had disease control after first-line treatment with platinum-based chemotherapy plus bevacizumab (Avastin) had significantly prolonged progression-free survival with maintenance bevacizumab/pemetrexed (Alimta) compared with bevacizumab alone.1 Toxicity was increased with bevacizumab/pemetrexed, although no new safety signals were observed.. Study Details. In this open-label multicenter trial, 376 patients with advanced nonsquamous NSCLC received first-line bevacizumab 7.5 mg/kg, cisplatin 75 mg/m2, and pemetrexed 500 mg/m2 once every 3 weeks for four cycles. Of these, 269 (72%) achieved disease control ...
The primary objective of this phase II study was to evaluate the efficacy of the dose level/regimen of everolimus recommended from the Phase I with trastuzumab and paclitaxel (PT) therapy in patients with HER2-overexpressing metastatic breast cancer whose disease progressed on/after trastuzumab mono-and/or combination therapy based on the evaluation of objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors (RECIST). Objective response rate (ORR) was defined as the proportion of patients with a best overall response (BOR) of complete response (CR) or partial response (PR). Only patients with measurable disease (the presence of at least one measurable lesion) at baseline were included in the study. CR = Disappearance of all target lesions; PR = At least a 30% decrease in the sum of the longest diameter of all target lesions, taking as reference the baseline sum of the longest diameters ...

Escalation to weekly dosing recaptures response in adalimumab-treated patients with moderately to severely active ulcerative colitis.
Colorectal cancer (CRC) is the fourth most frequently diagnosed cancer and the second leading cause of neoplasm-related death in the United States. Several studies analyzed the efficacy of bevacizumab combined with different chemotherapy regimens consisting on drugs such as 5-FU, capecitabine, irinotecan and oxaliplatin. This systematic review aims to evaluate the effectiveness and safety of chemotherapy plus bevacizumab versus chemotherapy alone in patients with previously untreated advanced or metastatic colorectal cancer (mCRC). Several databases were searched, including MEDLINE, EMBASE, LILACS, and CENTRAL. The primary endpoints were overall survival and progression-free survival. Data extracted from the studies were combined by using hazard ratio (HR) or risk ratio (RR) with their corresponding 95 % confidence intervals (95 % CI). The final analysis included 9 trials comprising 3,914 patients. Patients who received the combined treatment (chemotherapy + bevacizumab) had higher response rates (RR =

Trastuzumab (Herceptin; Genentech/Roche, South San Francisco, CA, USA), the first available HER2-targeted therapy, is a humanized murine IgG monoclonal antibody that binds to the HER2 ECD. Its antitumor activity has not been completely ascertained, however, it is thought to result from a combination of antibody-dependent cell-mediated cytotoxicity, inhibition of cleavage of the ECD of the HER2 (8), decreased DNA repair, decreased intracellular signal transduction and anti-angiogenic effects (9,10). Trastuzumab-based treatment strategy has established a milestone in the therapy of HER2-positive breast cancer with attractive clinical benefits in the treatment of metastatic breast cancer, as well as adjuvant chemotherapy and neoadjuvant chemotherapy.. Adding trastuzumab to chemotherapy in the first-line treatment of HER2-positive metastatic breast cancer (MBC) was based on the pivotal phase III trial in which 469 women with HER2-positive MBC were randomized to receive standard chemotherapy ...
06 Dec 2017. A combination of pembrolizumab and trastuzumab, tested in patients with trastuzumab-resistant advanced HER2-positive breast cancer, was well tolerated and had clinical benefit in patients whose tumors were positive for a biomarker for pembrolizumab, according to data presented from the phase Ib/II PANACEA trial at the 2017 San Antonio Breast Cancer Symposium, held Dec. 5-9.. We wanted to investigate if immunotherapy approaches can work in patients with advanced HER2-positive breast cancer that is resistant to trastuzumab, said Sherene Loi, MD, PhD, associate professor at Peter MacCallum Cancer Centre in Melbourne, Australia, working with the International Breast Cancer Study Group (IBCSG).. It is estimated that approximately 20 percent of invasive breast cancers are HER2-positive, and some of these patients develop resistance to trastuzumab, a HER2-specific monoclonal antibody utilized for treatment of the disease.. Loi and colleagues hypothesized that immunotherapy may help to ...
In this report, we describe the unexpected finding that cetuximab-based therapy is associated with an increase in CTLA-4+Foxp3+ Treg in the circulation and in the microenvironment in treated patients with HNSCC from two independent clinical trial cohorts. Indeed, higher levels of Treg correlated with worse prognosis in cetuximab-treated patients with HNSCC, as recently seen in lung cancer after neoadjuvant chemotherapy (31). For the first time, we also show that intratumoral NK cell activation and cytotoxicity occurs during cetuximab therapy, which is primarily inhibited by Treg-derived TGFβ1, providing a mechanism for their suppressive effect and impact on clinical course of the disease. Furthermore, we demonstrated that NK cells can selectively eliminate intratumoral Treg in the presence of ipilimumab, which induces recovery of cetuximab ADCC activity from Treg suppression. Importantly, the suppressive effect of these Treg could be substantially abrogated by ipilimumab-mediated NK cell ...
Trastuzumab is a drug used for the treatment of metastatic breast cancer patients. Due to blockage of the human epidermal growth factor receptor 2 signaling in cardiac myocytes, cardiotoxicity has been observed. There are many studies that investigated risk factors for trastuzumab-induced cardiotoxicity, but no study has been published for factors on the time to cardiotoxicity. This study aimed to investigate the factors for the time to occur trastuzumab-induced cardiotoxicity. From January 2014 to December 2015, a retrospective study was performed with breast cancer patients who were treated with trastuzumab. Associations between presence of and time to cardiotoxicity and various factors were analyzed. Based on multivariate models, it was found that baseline left ventricular ejection fraction (LVEF) < 62.5% (AHR 5.96, 95% CI 2543-13.95) and anthracycline-based chemotherapy (AHR 7.90, 95% CI 1.05-59.71) were significant factors for time to cardiotoxicity after adjusting other confounding ...
Rituximab plus polychemotherapy is standard of care in diffuse large B-cell lymphoma (DLBCL). GAINED trial compares obinutuzumab to rituximab. GAINED (NCT01659099) is an open-label, randomized phase 3 trial. Transplant-eligible patients (18-60yrs) with untreated aged-adjusted international prognostic index (aaIPI) ≥1 DLBCL were randomized (1:1) between obinutuzumab or rituximab. Patients were stratified by aaIPI (1; 2-3) and chemotherapy regimen (ACVBP; CHOP). Consolidation treatment was determined according to response assessed by centrally reviewed interim semi-quantitative PET. Responders after cycle 2 and 4 (PET2-/PET4-) received planned immuno-chemotherapy consolidation. Responders only after cycle 4 (PET2+/4-) received high-dose methotrexate plus transplantation. The primary objective was an 8% improvement (HR=0.73; 80% power; alpha risk 2.5%; one-sided) in 2-year event-free survival (EFS) in the obinutuzumab arm. Events included death, progression, PET 2 or 4 positivity, modification of ...

It is reported that pertuzumab and trastuzumab bind to different domains of HER2. A previous study showed that pertuzumab and trastuzumab were oriented at different angles with respect to HER2 after binding to HER2, by using a 3D structure model of the Fab region of pertuzumab and trastuzumab and p185HER2 (27). As shown in Figure 1A, binding of whole IgG to HER2 ECD protein, pertuzumab would not interfere with the binding of trastuzumab on HER2, even though both antibodies are displayed in their whole IgG conformation. This result indicates that pertuzumab and trastuzumab could have combination effects on antitumor activity.. We examined the efficacy of pertuzumab and trastuzumab in vivo. The reason for in vivo study is that the in vivo models indicate the efficacy of this antitumor activity more accurately because trastuzumab or pertuzumab have a mechanism through ADCC activity. We used NCI-N87 and 4-1ST as HER2-positive models. NCI-N87 and 4-1ST were determined as HER2 2+ and 3+, respectively ...

TY - JOUR. T1 - Trastuzumab-Induced Cardiomyopathy. AU - Guglin, Maya. AU - Cutro, Raymond. AU - Mishkin, Joseph D.. PY - 2008/6/1. Y1 - 2008/6/1. N2 - Trastuzumab is a recombinant humanized monoclonal antibody used for the treatment of advanced breast cancer. It improves survival and increases response to chemotherapy. The major side effect of trastuzumab is cardiotoxicity manifesting as a reduction in left ventricular systolic function, either asymptomatic or with signs and symptoms of heart failure. Although reversible in most cases, cardiotoxicity frequently results in the discontinuation of trastuzumab. The objective of this review is to summarize facts about trastuzumab-induced cardiotoxicity and to highlight the areas of future investigations. We searched PubMed for trials involving trastuzumab used as an adjuvant therapy for breast cancer, including the metastatic breast cancer setting, and focused on cardiotoxicity..

Trastuzumab, a monoclonal antibody targeting human epidermal growth factor receptor 2 (HER2; also known as HER-2/neu), is indicated for the treatment of women with either early stage or metastatic HER2+ breast cancer. It kills tumor cells by several mechanisms, including antibody-dependent cellular cytotoxicity (ADCC). Strategies that enhance the activity of ADCC effectors, including NK cells, may improve the efficacy of trastuzumab. Here, we have shown that upon encountering trastuzumab-coated, HER2-overexpressing breast cancer cells, human NK cells become activated and express the costimulatory receptor CD137. CD137 activation, which was dependent on NK cell expression of the FcγRIII receptor, occurred both in vitro and in the peripheral blood of women with HER2-expressing breast cancer after trastuzumab treatment. Stimulation of trastuzumab-activated human NK cells with an agonistic mAb specific for CD137 killed breast cancer cells (including an intrinsically trastuzumab-resistant cell line) ...
Corneal expression levels of the proinflammatory and pro(lymph)angiogenic cytokines IL-1β, TNFα, VEGF-A, VEGF-C, and VEGF-D were analyzed by real-time PCR after suture placement and treatment with serum eyedrops, bevacizumab eyedrops, or a combination of both. After 2 days of treatment, only bevacizumab affected IL-1β expression (serum mean of 95.6%, n.s.; bevacizumab mean of 74.3%, P , 0.01; and serum and bevacizumab mean of 96.4%, n.s.), whereas after 7 days of treatment, all treatment groups had significantly reduced IL-1β expression (serum mean of 48.4%, P , 0.001; bevacizumab mean of 58.9%, P , 0.001; and serum and bevacizumab mean of 53.2%, P , 0.001) (Fig. 5, top left). After 2 days of treatment, TNFα expression was significantly impaired only by bevacizumab (serum mean of 106.1%, n.s.; bevacizumab mean of 68.4%, P , 0.05; and serum and bevacizumab mean of 93.0%, n.s.), while after 7 days of treatment, the combination of serum and bevacizumab also showed considerable inhibition of ...

Genetic parameters are established prognostic factors in chronic lymphocytic leukemia (CLL) treated with chemoimmunotherapy but less well studied with novel compounds. We assessed IGHV mutation status, common genomic aberrations and gene mutations in 421 untreated patients within the CLL14 trial (NCT02242942) comparing obinutuzumab+chlorambucil (GClb) vs. obinutuzumab+venetoclax (VenG). The incidences of genomic aberrations considering the hierarchical model were del(17p) 7%, del(11q) 18%, +(12) 18% and del(13q) 35%, while IGHV was unmutated in 60% of patients. NOTCH1 mutations were most common (23%), followed by SF3B1 (16%), ATM (13%) and TP53 (10%). While the overall response rate (ORR) for GClb was lower in patients with del(17p), del(11q), mutated TP53, ATM and BIRC3, none of these parameters reduced complete remission (CR) and ORR with VenG. At a median follow-up of 28 months, del(17p) and mutated TP53 were the only abnormalities with impact on PFS for both treatment arms, GClb (HR 4.6, ...

PURPOSE: The addition of bevacizumab to cytotoxic chemotherapy has demonstrated a progression-free survival (PFS) benefit in the first-line and second-line treatment of advanced or metastatic breast cancer (MBC). However, the addition of bevacizumab to capecitabine in heavily pretreated MBC patients did not show a PFS benefit (AVF2119g phase III trial). The aim of this study was to evaluate the expression of novel putative biomarkers as predictors of benefit from bevacizumab in retrospective subset analyses of the AVF2119g trial. EXPERIMENTAL DESIGN: In the AVF2119g trial, 462 patients with MBC were randomly assigned to receive capecitabine or capecitabine plus bevacizumab. Primary tumor tissue and outcome data were available for 223 patients. Biomarker expression was assessed by in situ hybridization (VEGF-A, VEGF-B, thrombospondin-2 and Flt4) or immunohistochemistry (VEGF-C, PDGF-C, neuropilin-1, delta-like ligand (Dll) 4, Bv8, p53 and thymidine phosphorylase) on formalin-fixed, paraffin-embedded
In the TML trial, patients with good performance status and metastatic colorectal cancer who progressed on regimens containing bevacizumab received second-line therapy consisting of a different chemotherapy regimen with or without bevacizumab.67 This study met its primary end point, with patients continuing on bevacizumab having a modest improvement in overall survival (11.2 vs. 9.8 months; hazard ratio [HR], 0.81; 95% CI, 0.69-0.94; P=.0062).. The continuation of bevacizumab after progression on bevacizumab was also studied in a community oncology setting through a retrospective analysis of 573 patients from the US Oncology iKnowMed electronic medical record system.68 Bevacizumab beyond progression was associated with a longer overall survival (HR, 0.76; 95% CI, 0.61-0.95) and a longer postprogression overall survival (HR, 0.74; 95% CI, 0.60-0.93) on multivariate analysis.. Overall, the panel believes that these data (along with those from the VELOUR trial, discussed later) show that the ...
Herceptin (trastuzumab) is a monoclonal antibody. It belongs to a group of drugs made in the laboratory that are designed to attack specific cancer cells. Herceptin is given intravenously (by injection into a blood vessel) to treat some breast cancers. Genentech Inc., located in South San Francisco, manufactures Herceptin.. Herceptin targets cancer cells that overexpress, or make too much of, a protein called HER-2 or erb B2, which is found on the surface of cancer cells. Herceptin slows or stops the growth of these cells. Herceptin is used only to treat cancers that overexpress the HER-2 protein. Approximately 25 percent of breast cancers overexpress HER-2. These tumors tend to grow faster and are generally more likely to recur (come back) than tumors that do not overproduce HER-2. The amount of HER-2 protein in the tumor is measured in the laboratory using a scale from 0 (negative) to 3+ (strongly positive). The result helps the doctor determine whether a patient might benefit from treatment ...

Background: HER2 amplification is found in 5% of RAS wild type (RASWT) metastatic colorectal cancer (mCRC). Dual HER2 blockade with trastuzumab (T) and lapatinib (L), but not treatment with either drug alone, led to remarkable inhibition of tumor growth in patient-derived tumorgrafts of HER2-amplified mCRC. CRC-specific criteria for HER2 positivity by immunohistochemistry (IHC) and in situ hybridization (ISH) were defined retrospectively in 256 CRC paraffin embedded samples (HERACLES DGX criteria). The ensuing diagnostic algorithm was utilised to screen 1299 HER2-positive tumors for therapeutic targeting in patients in the HERACLES phase 2 trial.. Methods: HERACLES was conducted at 4 Italian centres. Eligibility criteria were: RASWT exon 2, HER2 positivity, refractoriness to standard of care (including cetuximab or panitumumab), PS-ECOG , 1, and measurable. HER2 positivity was defined by IHC and ISH according to HERACLES DGX criteria. Patients (PTS) received T i.v. at 4 mg/kg loading dose ...
Background. The CHER-LOB randomized phase II study showed that the combination of lapatinib and trastuzumab plus chemotherapy increases the pathologic complete re- mission (pCR) rate compared with chemotherapy plus either trastuzumab or lapatinib. A biomarker program was prospectively planned to identify potential predictors of sensitivity to different treatments and to evaluate treatment effect on tumor biomarkers. Materials and Methods. Overall, 121 breast cancer patients positive for human epidermal growth factor 2 (HER2) were randomly assigned to neoadjuvant chemotherapy plus trastu- zumab, lapatinib, or both trastuzumab and lapatinib. Pre-and post-treatment samples were centrally evaluated for HER2, p95- HER2, phosphorylated AKT (pAKT), phosphatase and tensin homolog, Ki67, apoptosis, and PIK3CA mutations. Fresh-frozen tissue samples were collected for genomic analyses. Results. A mutation in PIK3CA exon 20 or 9 was documented in 20% of cases. Overall, the pCR rates were similar in PIK3CA ...
Purpose: This phase Ib study was designed to determine the MTD, safety, preliminary efficacy, and pharmacokinetics of the HER3 (ErbB3) mAb SAR256212 in combination with the oral PI3K inhibitor SAR245408 for patients with metastatic or locally advanced solid tumors.. Experimental Design: Patients received the combination of intravenous SAR256212 and oral SAR245408 in a 3 + 3 dose-escalation design until occurrence of disease progression or dose-limiting toxicity. Objective response rate, pharmacokinetics, pharmacodynamics, and PIK3CA mutational status were also evaluated.. Results: Twenty-seven patients were enrolled. Thirteen of 20 patients tested (65%) had a hotspot-activating mutation in PIK3CA in their tumor. The MTD was determined to be SAR256212 at 40 mg/kg loading dose followed by 20 mg/kg weekly, plus SAR245408 200 mg daily. Dose-limiting toxicities included rash and hypotension; the most frequent treatment-related side effect was diarrhea (66.7%). Twenty-three patients were evaluable for ...

Why is my heart being monitored while Im on Herceptin?. Herceptin (trastuzumab) can cause heart problems, including an inability to pump blood effectively, irregular heartbeats, high blood pressure, disabling heart failure, weakening of the heart muscle, and sudden loss of heart function leading to death. Herceptin may cause reduced heart function even if there are no symptoms. Before taking your first dose of Herceptin, your doctor should check to see if you have any health conditions that may increase your chance of having serious heart problems. This includes a review of your health history and tests to see how well your heart muscle is working. These tests may include an echocardiogram, which is an ultrasound image of the heart, or a MUGA scan, which takes a moving picture of your heart pumping blood following an injection of a radioactive substance.. In addition, you should be frequently monitored for decreasing heart function during the time you are receiving Herceptin and after your last ...

Trastuzumab emtansine (T-DM1) is a novel antibodyCdrug conjugate, made up of a potent cytotoxic medication connected with a steady linker towards the anti-HER2 antibody, trastuzumab, mainly targeting chemotherapy delivery to cells overexpressing the HER2 receptor thus. of proteins is normally involved in marketing cell development through activation from the PI3K/Akt/mTOR as well as the Ras/Raf/MEK/MAPK pathways [2]. Amplification of HER2 is normally predictive of intense phenotype and poorer final result unless treated with anti-HER2 therapy Rabbit Polyclonal to BAIAP2L1. [3]. Summary of the marketplace Trastuzumab, a humanized anti-HER2 monoclonal antibody, is among the most set up gold regular treatment for HER2-amplified breasts cancer because it was first authorized by the united states FDA in 1998 [4,5]. Subsequently, two additional HER2-targeted agents have already been authorized for the treating HER2-positive metastatic breasts cancer, pertuzumab and lapatinib. Lapatanib, an dental ...
While approval of trastuzumab, a recombinant monoclonal antibody directed against HER2, along with a diagnostic kit to detect breast cancers which are positive for HER2 overexpression, has advanced a new era of stratified and personalized medicine, it also created several challenges to our scientific and clinical practice. These problems include trastuzumab resistance and trastuzumab-induced cardiotoxicity. In this review, we will summarize data from the literature regarding mechanisms of trastuzumab resistance and trastuzumab-induced cardiotoxicity and present some promising model systems that may advance our understanding of these mechanisms. Our discussion will include development of circulating tumor cells and circulating tumor DNA for monitoring tumor burden, of patient-derived xenograft models for preclinical testing of novel therapies, and of novel therapeutic strategies for trastuzumab-resistance and possible integration of these strategies in the design of co-clinical studies for testing in
Simplicity is enormously complex in the treatment of metastatic colorectal cancer. In terms of survival, life expectancy of patients with metastatic colorectal cancer improved substantially from 3 to 6 months in the 1980s when only 5-fluorouracil was available, to more than 20 months today with the availability of various new chemotherapeutic and targeted agents. The use of chemotherapeutic agents - including fluoropyrimidines, irinotecan, and oxaliplatin - has been refined through decades of clinical experience. Maximal exposure, irrespective of sequence, is simply the principle of treating patients through progression with chemotherapy. Targeted therapy has emerged in the past decade, and adds complexity to the treatment principle: survival benefit has been shown with both anti-vascular endothelial growth factor and anti-epidermal growth factor receptor antibodies in individual lines of treatment, but controversy exists as to the best sequence of application. Adding to this complexity, ...
Clinical trial for Relapsed/Refractory Follicular Non-Hodgkin Lymphoma , A Study Comparing Obinutuzumab and BGB-3111 Versus Obinutuzumab Alone in Treating R/R Follicular Lymphoma
The combination of trastuzumab with chemotherapeutic agents is a well established approach for treatment of HER2 positive metastatic breast cancer. Preclinical models and subsequent clinical data have demonstrated an additive or synergistic effect of the combination with platinum salts, paclitaxel, docetaxel, vinorelbine or more than one drugs [15-18].. Unfortunately, the success of these combinations in responding patients is compromised by the development of acquired resistance [4]. The mechanism of resistance to trastuzumab in animal models is the consequence of heritable genetic alterations and involved different, independent mechanisms [19]. The opportunity, in patients with progressive disease, of continuing trastuzumab combined with a non cross resistant chemotherapeutic regimen is a crucial question regarding trastuzumab strategy. Data on restored efficacy of trastuzumab with further associations after failure are limited, although some activity was recently reported in patients with ...
Although trastuzumab provides significant clinical benefit for HER2-positive breast cancers, responses are limited by the emergence of resistance. Recent evidence suggests that long noncoding RNAs (lncRNAs) play important roles in tumorigenesis and chemoresistance. However, the regulatory mechanism of lncRNAs in trastuzumab resistance is not well established to date. In this research, we identified the differentially expressed lncRNA and investigated its regulatory role in trastuzumab resistance of breast cancer. LncRNA microarray and qRT-PCR were performed to identify the dysregulated lncRNAs. Transmission electron microscopy, differential ultracentrifugation and qRT-PCR were used to verify the existence of exosomal AFAP1-AS1 (actin filament associated protein 1 antisense RNA 1). Bioinformatics prediction, RNA fluorescence in situ hybridization (RNA-FISH) and immunoprecipitation assays were performed to identify the direct interactions between AFAP1-AS1 and other associated targets, such as AU-binding

In the current multicentre retrospective study among the Chinese patients with breast cancer, over 70% were heavily pretreated with anti-HER2 agents as well as cytotoxic chemotherapy. The efficacy results are consistent with previous findings from the TH3RESA study.9 The latter involved over 600 HER2+ patients with advanced breast cancer who had received two or more anti-HER2-containing regimens, including trastuzumab and lapatinib, and previous taxane therapy. At a median follow-up of 6.5 months, the TH3RESA study reported that among the T-DM1-treated patients, the objective response rate was 31%, the median duration of response was 9.7 months, the median PFS was 6.2 months, and the median OS was not reached.9 Similarly, the safety profile in the current study was consistent with the reported clinical trials, where grade 3 or worse thrombocytopenia was the most commonly reported adverse event (13.5%), followed by raised alanine transaminase (8.1%), anaemia (5.4%), and hypokalaemia (2.7%). ...
Background We designed the randomized phase III LEA study of first-line bevacizumab in combination with endocrine therapy, to address the hypothesis that anti-VEGF treatment can prevent resistance to endocrine therapy in patients (pts) with advanced breast cancer sensitive to such treatment.. Methods A multicentre, binational, randomised, open label, phase III study investigated the addition of Bevacizumab (B) 15mg/kg every 3 weeks to an endocrine therapy (ET) with letrozole or fulvestrant (250mg/4 weeks) as first-line therapy in metastatic breast cancer. Postmenopausal pts with HER2-negative and hormone-receptor-positive breast cancer were eligible. The primary objective was to compare progression-free survival (PFS) in the treatment arms. Secondary objectives were overall survival, time to treatment failure, overall response rate, response duration, clinical benefit rate and safety. The recruitment was completed in September 2011. Efficacy analysis will be triggered after 270 events.. Results ...
On February 15, 2017, Genentech filed litigation accusing Amgen of violating the Biologics Price Competition and Innovation Act (BPCIA), 42 U.S.C. § 262.

HER-2 is a 185-kDa orphan transmembrane receptor tyrosine kinase. Dimerization of HER-2 with ligand- bound HER-3 or HER-4 receptor activates signaling pathways inside the cell. Activated HER-2 signaling stimulates cell proliferation and survival via activation of the MAPK and PI3K/Akt/mTOR pathways. Collectively these signaling pathways result in uncontrolled growth of the tumor. Several studies suggested that the overexpression/amplification of HER-2 may lead to the development and progression of pre-malignant breast disease and also tumor metastasis. Therefore, the association of HER-2 in breast cancer as well as its involvement in tumor aggressiveness makes this receptor an appropriate target for tumor-specific therapies. Several strategies have been developed to inhibit HER-2 signaling. These include a tyrosine kinase inhibitor called lapatinib and a recombinant humanized monoclonal antibody called trastuzumab (Herceptin®). In this post I will focus only on trastuzumab mediated therapy in ...

Background CRC is the second leading cause of cancer death in Canada. Bevacizumab, a recombinant humanised monoclonal antibody that selectively binds to human vascular endothelial growth factor, is approved and funded for first line mCRC use in Canada. A substudy has also confirmed its effectiveness in KRAS wild-type patients. Recent evidence has also shown clinical benefit from anti-epidermal growth factor treatments panitumumab and cetuximab in these patients. Objective: We assessed cost-effectiveness of fluoropyrimidine-based chemotherapy (FBC) alone and in combination with bevacizumab, panitumumab or cetuximab for first line treatment of KRAS wild-type mCRC patients.. Methods Cost-effectiveness to the Canadian health care system was estimated using separately reported trial survival and adverse event results for each comparator. We used a Markov model calibrated to progression-free/overall survival, and calculated quality-adjusted life years (QALYs). Health-state resource utilization was ...
Serum levels of HAHAs were detected by a newly developed radioimmunoassay, a specific assay measuring high avid antibodies against adalimumab, similar to that described for rituximab.4. HAHAs were present after cessation of treatment for the planned surgical procedure, whereas serum levels of adalimumab were undetectable (fig 1). As levels of HAHAs increased, levels of adalimumab dropped and disease activity increased.. Our patient developed HAHAs to adalimumab despite the fact that adalimumab is a human monoclonal antibody. Infliximab is a chimeric antibody and can induce an immunogenic reaction in the form of human antichimeric antibodies. The development of HACAs to infliximab is associated with a reduced response to treatment,5 and so far such relationships have not been described for adalimumab.. In our patient, the anti-rheumatic drug-free period may have influenced the development of HAHAs. The absence of the protective role of methotrexate may have stimulated the formation of HAHAs. ...
Obinutuzumab is an immunotherapy medicine used in the treatment of CLL and Non Hodgkin lymphoma and works by binding to a protein on the surface of certain white cells known as B lymphocytes .By bonding to this protein the abnormal growth in the B lymphocyte is stopped therefore decreasing the number of cancer cells in the body.. Once attached to the CD20 protein Obinutuzumab helps the immune system destroy the CLL cells and also destroys the CLL cells on its own by directly killing them.

Cetuximab, an antibody directed against the epidermal growth factor receptor, is an effective clinical therapy for patients with colorectal, head and neck, and non-small cell lung cancer, particularly for those with KRAS and BRAF wild-type cancers. Treatment in all patients is limited eventually by the development of acquired resistance, but little is known about the underlying mechanism. Here, we show that activation of ERBB2 signaling in cell lines, either through ERBB2 amplification or through heregulin up-regulation, leads to persistent extracellular signal-regulated kinase 1/2 signaling and consequently to cetuximab resistance. Inhibition of ERBB2 or disruption of ERBB2/ERBB3 heterodimerization restores cetuximab sensitivity in vitro and in vivo. A subset of colorectal cancer patients who exhibit either de novo or acquired resistance to cetuximab-based therapy has ERBB2 amplification or high levels of circulating heregulin. Collectively, these findings identify two distinct resistance ...
Background: The treatment of recurrent anaplastic glioma (AG) like all high-grade gliomas (HGG) is problematic, as only partially effective therapeutic modalities are available and there is a lack of a standard therapy for recurrence. Methods: A literature review of the use of bevacizumab for recurrent HGG including five studies involving recurrent AG. Results: In the 5 studies of bevacizumab for the treatment of recurrent AG (n=140 patients) neuroradiographic response rates were as follows; complete response 0-20%, partial response 34-68% (median 52%), and stable disease 5-59% (median 16%). Median overall survival was 28 weeks (range 18-35 weeks) and progression free survival at 6- and 12-months was 55% (range 32-68%) and 23% (16-39%) respectively. Conclusions: Bevacizumab therapy appears to increase response of recurrent AG by 2-fold and 6- month progression free survival by 1.5 fold without a clear benefit with respect to overall survival. Toxicity of bevacizumab therapy is manageable and ...
Several adverse events have been associated with the use of bevacizumab during the treatment of neoplasms such as colorectal cancer, breast cancer, non-small cell lung cancer, pancreatic cancer and renal cell carcinoma. The present case demonstrates how focal neurological symptoms lead to the magnetic resonance imaging-based differential diagnosis between focal parenchymal metastases and microischemic phenomena, with crucial implications for patient management. We describe the case of a 37-year-old Italian Caucasian woman with metastatic colon cancer who developed focal neurological symptoms during a chemotherapy regimen involving the use of bevacizumab. Brain magnetic resonance imaging examination revealed millimetric lesions with restricted diffusion without perilesional edema or contrast enhancement after gadodiamide intravenous injection, suggestive of acute microischemic phenomena. This complication is very rare but clinically significant. The differential diagnosis in patients with cancer

In December 2010 the U.S. Food and Drug Administration (FDA) recommended removing the indication for Avastin (chemical name: bevacizumab) in combination with Taxol (chemical name: paclitaxel) to treat metastatic, HER2-negative breast cancer that hasnt been treated with chemotherapy.. Genentech, the company that makes Avastin, has asked for a full FDA hearing to again present currently available research on Avastin and to review plans for future research that could help both the FDA and doctors better understand which patients would most benefit from Avastin to treat advanced-stage breast cancer.. The FDA made its recommendation to remove the Avastin breast cancer indication because it said Avastin hasnt been shown to be safe and effective for that use. Removing that indication would be a process and the full hearing requested by Genetech is the first step in that process. The medicine itself is not being removed from the market and the recommendation should not have any immediate affect on its ...
