Project description:Germ cell tumors (GCTs) can be cured with cisplatin-based therapy, although a clinically significant number of patents are refractory and die of progressive disease. Based on preclinical studies indicating that refractory testicular GCTs are hypersensitive to hypomethylating agents (HMA), we conducted a phase I trial [NCT02429466] of the next-generation HMA guadecitabine (SGI-110) in combination with cisplatin in patients with recurrent, cisplatin-resistant GCTs. The primary endpoint was safety and toxicity including DLT and MTD. A total of 14 patients were enrolled. The majority of patients were heavily pretreated. MTD was determined to be 30 mg/m2 guadecitabine followed by cisplatin 100 mg/m2. DLTs were neutropenia and thrombocytopenia. Three patients had partial responses by RECIST criteria, two of these patients qualified as complete responses by serum tumor marker criteria with survival of 16 and 26 months. Three patients also had stable disease for an overall response rate of 23% and clinical benefit rate of 46%. Genome-wide analysis pre- and post-guadecitabine indicated dramatic and widespread global DNA demethylation in cell-free plasma samples including in the promoters of genes of cancer related pathways. In summary, the combination of guadecitabine followed by cisplatin was tolerable and demonstrated biological activity in patients with platinum refractory GCTs.

Project description:This phase II study examined the pathological complete response (pCR) rate and safety of two gemcitabine-based combinations administered sequentially in breast cancer. We also examined gene expression profiles from tumor biopsies to identify biomarkers predictive of response. Methods: Indian women with large or locally advanced breast cancer received 4 cycles of gemcitabine 1200 mg/m2 plus doxorubicin 60 mg/m2 (Gem+Dox), then 4 cycles of gemcitabine 1000 mg/m2 plus cisplatin 70 mg/m2 (Gem+Cis), and surgery. To examine dynamic changes in molecular profiles after one dose of therapy, we used three alternate sequences during cycle 1 (Gem d1, 8; Dox d2; Gem d1, 8; Dox d1; or Gem d2, 8; Dox d1). Results: Of 65 women (median age 46) treated, 13 (24.5% of 53 patients with surgery) had a pCR and 22 (33.8%) had a complete clinical response. Patients who received Gem d1, 8 and Dox d2 in cycle 1 (20/65) reported more toxicities, with G3/4 neutropenic infection/febrile neutropenia (7/20) and vomiting (5/20) as the most common cycle 1 events. Four drug-related deaths occurred. 46/65 patients yielded successful pretreatment gene expression profiles. Ten-fold cross-validated supervised analyses identified gene expression patterns that predicted with >73% accuracy (1) clinical complete response after eight cycles, (2) overall clinical complete response, and (3) pCR. Conclusions: This neoadjuvant regimen showed strong activity. A subset of patients receiving Gem d1, 8 and Dox d2 experienced unacceptable toxicity, whereas patients on other sequences had more manageable safety profiles. The predictive gene expression patterns may provide a method for selecting patients most likely to benefit from gemcitabine-containing neoadjuvant therapy.

Project description:This phase I/II neoadjuvant trial determined maximally-tolerated doses (MTD), dose-limiting toxicities (DLT), response-to-therapy, and explored the role of new response biomarkers. The combination regimens were delivered with acceptable toxicity, good clinical response, inducing changes in tumor RNA content and integrity. Pre-treatment gene expressions impacted clinical response, including several near 17q12, which with ERBB2, may better identify chemoresponsiveness. The NCIC Clinical Trials Group MA.22 phase I/II clinical trial (ClinicalTrials.gov identifier NCT00066443) sought to determine the optimal dosing regimens for docetaxel/epirubicin combination chemotherapy in women with locally advanced (over 95% of patients) or inflammatory breast cancer. The protocol was approved by Health Canada and local Ethics Review Boards, and patients provided written, informed consent. Various doses of epirubicin and docetaxel were administered to patients in either a standard q3 weekly (Schedule A) or dose dense q2 weekly (Schedule B) regimen. Doses for Schedule A were 75 mg/m2 IV of docetaxel and 75, 90, 105, or 120 mg/m2 IV of epirubicin (with 6 mg of pegfilgrastim per cycle on day 2 to prevent neutropenia). Doses for both docetaxel and epirubicin in Schedule B were 50, 60, and 70 mg/m2 IV (with identical pegfilgrastim support). For each schedule, phase I was dose finding for phase II. Patients were allocated to the various phases and dosing regimens of the trial without randomization. None of the patients received trastuzumab in the initial years of the study and HER2+ patients were not enrolled on study, once trastuzumab funding became available. Six tumor biopsy cores were obtained pre-, mid-, and post-treatment: 3 cores for pathologic assessment; 3 cores for microarray studies. Total RNA was isolated from these cores and RNA integrity was assessed using Agilent Bioanalyzer. One of the RNA samples with the best quality was used for microarray study. One colour microarray of Agilent whole human genome nucleotide arrays was conducted with one array per patient. The current data set represents pre-treatment set. MA.22 clinical trial accrued T3N0, any N2 or N3, and T4 breast cancer patients (according to the classification described at; http://emedicine.medscape.com/article/2007112-overview). However, since the current study does not focus on the tumor grade/stage, the information was not provided in the current records.

Project description:A phase I trial of a SRC kinase Inhibitor, dasatinib, in combination with paclitaxel and carboplatin in patients with advanced or recurrent ovarian cancer. Background: We conducted a phase I study of dasatinib, an oral SRC tyrosine kinase inhibitor, in combination with paclitaxel and carboplatin in advanced and recurrent epithelial ovarian cancer (EOC). Methods: The primary objective was to determine the maximum tolerated dose (MTD). Secondary objectives included toxicity, response rate (RR), pharmacokinetics and pharmacodynamics. Based on the 3+3 design, cohorts of 3-6 pts received paclitaxel 175 mg/m2 and carboplatin AUC 6 every three weeks with escalating doses of dasatinib (100, 120, 150 mg daily), followed by an 8 patient expansion cohort. Results: Twenty patients were enrolled between 06/07 and 12/09. The median age was 61 yrs (42-82) with a median of 2 prior regimens (0-6), and 71% had platinum-sensitive disease. There were 3-6 pts in each cohort, and 8 in the expansion cohort. Pharmacokinetics were observed over the first 2 cycles of therapy. One DLT was observed in the 100 mg dasatinib cohort (grade 3 myalgia. Other toxicities in all cycles included neutropenia (95% grade 3-4), thrombocytopenia (35% grade 3-4), and fatigue (10% grade 3). The RR was 45% (complete responses, 3/18(17%); partial responses, 5/18(28%)) and 56% (10/18) had stable disease. The PFS6-month actuarial estimate was 86%. The median PFS and OS were 7.8 and 16.2 months, respectively. Conclusions: Due to the high incidence of myelosuppression with subsequent cycles the recommended phase II dose is 150 mg daily of dasatinib in combination with paclitaxel and carboplatin. The combination was safe with evidence of clinical activity in advanced EOC. Global profiles of expression were characterized using unsupervised clustering methods and gene- and pathway-analyses of differential expression.

Project description:DNA copy number profiles can identify patients with a defect in BRCA1 or BRCA2. We previously showed that patients with a BRCA1 like profile benefit from intensified alkylating chemotherapy (IA, 4 cycles 5-fluorouracyl (5FU), epirubicin, cyclophosphamide (C) + 1 cycle carboplatin, thiotepa and cyclophosphamide with autologous stem cell transplantation (ASCT)). Presumably, this is because of the defect in error free homologous recombination DNA repair. Here we present an independent study IA chemotherapy (2 cycles induction, followed by ifosfamide, 12 g/m2; carboplatin, 900 mg/m2; and epirubicin, 180 mg/m2 with ASCT) versus anthracyclin-C (AC) or C-methothrexate-5FU (CMF) regimens in high risk breast cancer.

Project description:KW-2450 is an oral dual insulin-like growth factor-1 receptor/insulin receptor tyrosine kinase inhibitor. We investigated the in vitro and in vivo preclinical activity of KW-2450 plus lapatinib and letrozole and conducted a phase I trial of the triple-drug combination in one male and 10 postmenopausal female patients with advanced/metastatic hormone receptorpositive, human epidermal growth factor receptor 2 (HER2)-positive breast cancer. A series of in vitro and in vivo animal studies was undertaken of KW-2450 in combination with lapatinib and hormonal agents. The phase I trial was conducted to establish the safety, tolerability, and recommended phase II dose (RP2D) of KW-2450 administered in combination with lapatinib and letrozole. Preclinical studies showed KW-2450 and lapatinib act synergistically to induce in vitro apoptosis and inhibit growth of HER2-positive MDA-MB-361 and BT-474 breast cancer cell lines. This combined effect was confirmed in vivo using the MDA-MB-361 xenograft model. KW-2450 showed synergistic in vitro growth inhibition with letrozole and 4-hydroxytamoxifen in ER-positive MCF-7 breast cancer cells and MCF-7-Ac1 aromatase-transfected MCF-7 cells. In the phase I study, dose-limiting toxicity (DLT; grade 3 rash and grade 3 hyperglycemia, respectively) occurred in two of three patients at the dose of KW-2450 25 mg/day plus lapatinib 1500 mg/day and letrozole 2.5 mg/day. The RP2D of the triple-drug combination was established as KW-2450 25 mg/day, lapatinib 1250 mg/day, and letrozole 2.5 mg/day with no DLT at this dose level.

Project description:By studying differently expressed immune genes with gene expression profiling in immune competent children researchers have been able to distinguish between children with asymptomatic viral infection and those with symptomatic viral infection as well as patients with bacterial infection. In this study we asked if gene expression profiling is feasible as a diagnostic tool in febrile neutropenia. We included children under treatment for a malignancy presenting with febrile neutropenia. Clinical data regarding the infectious episode was prospectively collected and children grouped based on microbiological agent detected into virus, bacteria, co-infection and unknown aetiology. Fourty three episodes had sufficient RNA for RNA-sequencing, 15 with respiratory tract virus, 22 with unknown etiology, 4 with co-infection and 2 with bacteria. No pathogen specific host-innate immune expression profile was seen in the group with virus, bacteria nor unknown aetiology probably due to the low white blood cell account (WBC). In the co-infection group with higher WBC but lower absolute neutrophil count (ANC) compared to the other groups, a downregulated innate response were detected. We conclude that gene expression profiling in children presenting with neutropenic fever is not a feasible diagnostic tool for febrile neutropenia in children with cancer due the low WBC.:

Project description:This randomized clinical trial studies prophylactic colony stimulating factor management in patients with breast, colorectal or non-small cell lung cancer receiving chemotherapy and with risk of developing febrile neutropenia. Patients receiving chemotherapy may develop febrile neutropenia. Febrile neutropenia is a condition that involves fever and a low number of neutrophils (a type of white blood cell) in the blood. Febrile neutropenia increases the risk of infection. Colony stimulating factors are medications sometimes given to patients receiving chemotherapy to prevent febrile neutropenia. Colony stimulating factors are given to patients based on guidelines. Some clinics have an automated system that helps doctors decide when to prescribe them when there is a high risk of developing febrile neutropenia. Gathering information about the use of an automated system to prescribe prophylactic colony stimulating factor may help doctors use colony stimulating factor when it is needed.

Project description:Phase I Safety, Pharmacokinetic and Pharmacogenomic Trial of ES-285, a Novel Marine Cytotoxic Agent Administered as an Infusion over 24 h Every 21 Days in Patients with Solid Tumors Purpose: A dose-escalation, phase I study evaluated the safety, pharmacokinetics, pharmacogenomics and efficacy of ES-285, a novel agent isolated from a marine mollusc, in adult cancer patients. Experimental design: Patients received a 24-hour i.v. infusion of ES-285 once every 3 weeks until disease progression or unacceptable toxicity. The starting dose was 4mg/m2. Dose escalation proceeded according to the worst toxicity observed in the previous cohort. Results: 28 patients were treated with 72 courses of ES-285 across 8 dose levels. No doselimiting toxicities (DLTs) were seen between 4mg/m2 and 128mg/m2. Two out of 4 patients treated at 256mg/m2 had dose-limiting reversible grade 3 transaminitis; one patient at 256mg/m2 also had transient grade 3 central neurotoxicity. One of 3 patients subsequently treated at 200mg/m2 died following drug-related central neurotoxicity. Pharmacokinetic studies indicated dose-proportionality with high volume of distribution (median Vss at 256mg/m2 was 2389L, range 1615-4051L) and long elimination half life (median t1/2 at 256mg/m2 was 29h, range 21-32h). The 3 patients with DLT had the highest drug exposure. Pharmacogenomic studies of paired surrogate tissue samples identified changes in gene expression following treatment that correlated with increasing dose. Pre-treatment 59- and 49-gene sets were identified in blood and skin respectively, that may predict DLT. Disease stabilisation for 6 to 18 weeks was recorded in 9 patients. Conclusion: Using this schedule, 128 mg/m2 was considered safe and feasible. At this dose, pharmacologically relevant concentrations of drug were safely achieved with pharmacogenomic studies indicating changes in the expression of genes of potential biological relevance.
