Erlotinib, an epidermal growth factor receptor (EGFR) inhibitor, may have off-target activity inducing acute myeloid leukemia (AML) differentiation, possibly through SYK inhibition. We investigated erlotinib in a pilot phase II study for efficacy in relapsed/refractory AML patients at a dose of 150 mg once daily in 28-day cycles. Twenty-nine patients were treated for a median of 29 days (range 12-142 days). Seven patients (24%) received > 1 cycle of therapy and 12 (41%) discontinued treatment before day 28 ...
Background Improving the survival of patients diagnosed with metastatic colorectal cancer requires the use of chemotherapy to be managed with minimum adverse effects. Randomized control trials (RCTs) have shown promising results with a combination of bevacizumab and erlotinib to block two important tumor growth pathways, namely vascular endothelial growth factor and epidermal growth factor receptor. Aim of the Review We aimed to examine the efficacy and safety of the combination of bevacizumab and erlotinib...
Leptomeningeal metastases (LMs) were devastating metastatic complications of non-small cell lung cancer (NSCLC). Management of LMs relied on conventional therapy but with poor survival, lacking effective treatment strategies. We present the case of a 52-year-old female non-smoker with advanced lung adenocarcinoma and initially positive EGFR-mutation, who failed to the treatment of standard first-line chemotherapy (pemetrexed plus cisplatin) and bevacizumab (BEV), and maintenance therapy with pemetrexed plus...
Erlotinib is used for treating non-small cell lung cancer (NSCLC). Intestinal absorption of erlotinib is impaired under gastric pH elevation, therefore, co-administration of gastric acid suppressants may provide lower blood concentration of erlotinib. We investigated the effects of erlotinib co-administration with proton pump inhibitors (PPI) and histamine H2 receptor blockers (H2RB) on the plasma concentration of erlotinib and erlotinib-induced adverse reaction in NSCLC patients.
Radical prostatectomy is one of the treatment of choices for localized prostate cancer. Published data show that radical prostatectomy is associated with both an increase and decrease in testosterone levels. This study aimed to document the changes in pre- and postoperative serum testosterone levels after radical prostatectomy along with the associations between serum testosterone levels and prostate cancer profiles in Thai population. Localized and locally advanced prostate cancer patients who elected to h...
Introduction Based on preclinical cytotoxic synergy between tipifarnib and erlotinib, a phase I study of this combination was conducted in patients with advanced solid tumors to evaluate safety, tolerability, maximum tolerated dose (MTD) and preliminary evidence of efficacy. Methods Patient enrollment followed the traditional "3 + 3" dose escalation scheme, through 4 dose levels, ranging from tipifarnib 200 mg twice daily plus erlotinib 75 mg once daily to tipifarnib 300 mg twice daily plus erlotinib 150...
To evaluate intravitreal bevacizumab every 2 weeks (biweekly) in refractory neovascular age-related macular degeneration (nAMD).
The phase II JO28638 study evaluated first-line onartuzumab plus erlotinib in patients with MET-positive advanced, metastatic, or post-operative recurrent non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutations. The study was stopped following termination of the global METLung study (OAM4971g), which showed lack of efficacy in the onartuzumab/erlotinib arm. We present immature efficacy and safety data from JO28638.
With the advent of next-generation sequencing (NGS), targeted sequencing is now contributing to decision making for which chemotherapeutics to administer to cancer patients, especially in refractory and metastatic cancer. Given that most patients with refractory cancer develop resistance to chemotherapy and have few treatment options, we performed NGS test to evaluate the efficacy and clinical feasibility of NGS-based targeted anticancer therapy. We used a gene panel for capturing target regions covering 83...
Erlotinib is used to treat non-small-cell lung cancer (NSCLC). Erlotinib was subsidized on the Pharmaceutical Benefits Schedule in Australia for the treatment of advanced stage (IIIB or IV) NSCLC (August 2008). In the pivotal trial supporting initial subsidy, erlotinib increased overall survival (OS) by 2 months compared with placebo (adjusted hazard ratio, 0.70; 95% confidence interval: 0.58-0.85). We examined the effectiveness of erlotinib in a 'real-world' setting by measuring survival outcomes in NSCLC ...
Acquired docetaxel (Doc) resistance in hormone-refractory prostate cancer (HRPC) remains an ongoing clinical challenge, resulting in failed chemotherapy and tumor recurrence. However, the mechanism of Doc-resistance development in prostate cancer cells is still unclear. Here, we observed a subpopulation of prostate cancer cells, in both Doc-resistant cell lines and the tumors of patients with HRPC, which show stem cell markers and greater tumorigenic potential. Those stem-like prostate cancer cells show hig...
Switch maintenance therapy, using alternative agents that were not administered during induction chemotherapy, is a treatment option for advanced non-squamous non-small cell lung cancer (NSCLC). Bevacizumab is known to increase the efficacy of other chemotherapeutic agents; however, switch maintenance therapy with docetaxel and bevacizumab has not been adequately studied. The goal of this study was to evaluate the efficacy and safety of switch maintenance therapy with docetaxel and bevacizumab following ind...
Previous studies have shown that metastatic colorectal carcinoma (mCRC) patients treated with bevacizumab, experience variation in the plasma levels of angiogenesis growth factors and related cytokines, called angiogenic switch (AS). The aim of the present study was to analyze the relationship between AS and the clinical response during standard chemotherapy-bevacizumab treatment.
Regulation of prostate cancer by androgen and androgen receptor (AR), and blockade of AR signaling by AR antagonists and steroidogenic enzyme inhibitors have been extensively studied. G protein-coupled receptors (GPCRs) are a family of membrane receptors that regulate almost all physiological processes. Nearly 40% of FDA-approved drugs in the market target GPCRs. A variety of GPCRs that mediate reproductive function have been demonstrated to be involved in the regulation of prostate cancer. These GPCRs incl...
This study aims to investigate the serum adiponectin, interleukin (IL)-6 and oxidative stress in epilepsy patients who are refractory or non-refractory to treatments.
The aim of this study was to evaluate the outcomes of neoadjuvant chemotherapy (NAC) with bevacizumab (Bev) at our institute.
Efficacy and safety of abiraterone acetate plus prednisone in Japanese patients with newly diagnosed, metastatic hormone-naïve prostate cancer: a subgroup analysis of LATITUDE, a randomized, double-blind, placebo-controlled, Phase 3 study.
To evaluate the efficacy and safety of abiraterone acetate plus prednisone (AAP) plus androgen-deprivation therapy (ADT) in Japanese subgroup with newly diagnosed, metastatic hormone-naïve prostate cancer (mHNPC) from Phase 3, randomized, global LATITUDE study.
To evaluate the capacity of 18f-fluorocholine positron emission tomography/computed tomography (FCH PET/CT) to detect biochemical recurrence of prostate cancer and to determine the correlation with PSA kinetics and influence of antiandrogen hormone therapy.
Current treatment strategies provide minimal results for patients with castration-resistant prostate cancer (CRPC). Attempts to target the androgen receptor have shown promise, but resistance ultimately develops, often due to androgen receptor reactivation. Understanding mechanisms of resistance, including androgen receptor reactivation, is crucial for development of more efficacious CRPC therapies. Here, we report that the RON receptor tyrosine kinase is highly expressed in the majority of human hormone-re...
Low-molecular-weight protein tyrosine phosphatase (LMW-PTP) expression affects carcinogenesis in various cancers and has been associated with determining the overall survival among men with metastatic hormone-naïve prostate cancer (mHNPC). In this study, we analyzed the value of LMWPTP for prediction of time to castration-resistant prostate cancer (CRPC) for men with mHNPC.
Angiogenesis inhibition with bevacizumab, a monoclonal antibody against vascular endothelial growth factor A (VEGF-A), is an anticancer treatment associated with hypertension and renal glomerular toxicity referred to as a preeclampsia-like syndrome. In preeclampsia, podocyturia predates proteinuria and clinical features of preeclampsia, and is regarded as a biomarker of ongoing glomerular injury. Using a quantitative polymerase chain reaction of the podocyte-specific molecules nephrin, podocin, and VEGF-A i...
Anti-epithelial growth factor receptor (EGFR) antibodies cetuximab (Cmab) and panitumumab (Pmab) have shown survival benefit for metastatic colorectal cancer (mCRC) patients. This study aimed to compare Pmab and Cmab according to the interval between bevacizumab discontinuation and anti-EGFR antibody initiation (bevacizumab-free interval; BFI).
