ABSTRACT

BACKGROUND: A randomised study to assess the addition of apatorsen, an antisense oligonucleotide that inhibits Hsp27 expression, to docetaxel in patients with metastatic urothelial carcinoma (mUC) relapsed after prior platinum-based chemotherapy. METHODS: Multicentre, phase II study with 1:1 randomisation to apatorsen (three loading doses at 600 mg intravenous followed by weekly doses) plus docetaxel (75 mg/m2 intravenous every 21 days) (A/D) or docetaxel alone. Overall survival (OS) was the primary end point with a P value <0.1 (one-sided) being positive. Progression-free survival (PFS), objective response rate (ORR), safety, and effect of Hsp27 levels on outcomes were secondary end points. RESULTS: Patients randomised to A/D (n = 99) had improved OS compared to docetaxel alone (n = 101): HR: 0.80, 80% CI: 0.65-0.98, P = 0.0784, median 6.4 vs 5.9 months. PFS and ORR were similar in both arms. A/D had more incidence of sepsis and urinary tract infections. Patients with baseline Hsp27 levels <5.7 ng/mL had improved OS compared to those with levels ≥5.7 ng/mL. Patients with a decline or ≤20.5% increase in Hsp27 from baseline benefited more from A/D than those with >20.5% increase. CONCLUSIONS: A/D met its predefined OS end point in patients with platinum-refractory mUC in this phase II trial. This trial is hypothesis generating requiring further study before informing practice.

ABSTRACT

OBJECTIVE: To assess and refine competencies for the clinical research data management profession. MATERIALS AND METHODS: Based on prior work developing and maintaining a practice standard and professional certification exam, a survey was administered to a captive group of clinical research data managers to assess professional competencies, types of data managed, types of studies supported, and necessary foundational knowledge. RESULTS: Respondents confirmed a set of 91 professional competencies. As expected, differences were seen in job tasks between early- to mid-career and mid- to late-career practitioners. Respondents indicated growing variability in types of studies for which they managed data and types of data managed. DISCUSSION: Respondents adapted favorably to the separate articulation of professional competencies vs foundational knowledge. The increases in the types of data managed and variety of research settings in which data are managed indicate a need for formal education in principles and methods that can be applied to different research contexts (ie, formal degree programs supporting the profession), and stronger links with the informatics scientific discipline, clinical research informatics in particular. CONCLUSION: The results document the scope of the profession and will serve as a foundation for the next revision of the Certified Clinical Data Manager TM exam. A clear articulation of professional competencies and necessary foundational knowledge could inform the content of graduate degree programs or tracks in areas such as clinical research informatics that will develop the current and future clinical research data management workforce.

ABSTRACT

BACKGROUND: 2-Methoxyestradiol (Panzem, 2ME2) is an endogenous metabolite of estradiol that destabilizes microtubules and exerts anti-angiogenic properties. This study was conducted to determine the activity and safety of 2ME2 administered as a NanoCrystal dispersion (NCD) formulation in patients with recurrent, platinum-resistant epithelial ovarian cancer (EOC). METHODS: Eligible patients had relapsed, platinum-resistant or refractory EOC with measurable or detectable disease. There was no limit on the number of prior treatment regimens. 2ME2 NCD 1000 mg orally four times daily (q.i.d.) was administered continuously during 4 week cycles. The primary endpoint was objective response rate (ORR). Secondary endpoints were assessment of toxicity, rate of clinical benefit defined as the number of patients experiencing an objective response, a CA125 response or stable disease (SD) >3 months, mean change in CA-125, progression-free survival (PFS), and pharmacokinetic analyses of 2ME2. RESULTS: Eighteen patients were enrolled. Median age was 65.5 (range 40-73). Patients had received a median of five prior treatments. The most common adverse events were fatigue (78%), nausea (78%), diarrhea (39%), neuropathy (50%), edema (39%), and dyspnea (44%), the majority being grade 1-2. There were no objective responses, but seven patients had SD as best response. Of those, two patients had SD for greater than 12 months. The rate of clinical benefit was 31.3%. Fairly stable plasma levels of 2ME2 ranging within the predicted therapeutic window were observed. CONCLUSIONS: The NCD formulation of 2ME2 is well tolerated in patients with heavily pretreated EOC. Few of these heavily pretreated patients had sustained stable disease.

ABSTRACT

PURPOSE: Concurrent chemoradiotherapy is standard treatment for patients with inoperable stage III non-small-cell lung cancer (NSCLC). A phase II study by the Southwest Oncology Group using consolidation docetaxel after cisplatin (P), etoposide (E), and radiation (XRT) resulted in a median survival time (MST) of 26 months. This randomized phase III trial evaluated whether consolidation docetaxel was responsible for this improved survival. PATIENTS AND METHODS: Eligible patients had stage IIIA or IIIB NSCLC, baseline performance status of 0 to 1, forced expiratory volume in 1 second >or= 1 L, and less than 5% weight loss. Patients received P 50 mg/m(2) intravenously (IV) on days 1, 8, 29, and 36 and E 50 mg/m(2) IV on days 1-5 and 29-33 concurrently with chest XRT to 59.40 Gy. Patients who did not experience progression were randomly assigned to docetaxel 75 mg/m(2) IV every 21 days for three cycles versus observation. The primary end point was to compare overall survival (Kaplan-Meier analysis). RESULTS: On the basis of evidence of futility, a data and safety monitoring board recommended early termination after an analysis of the initial 203 patients. Patient characteristics (n = 203) were as follows: 34% female; median age, 63 years; 39.4% stage IIIA; and 60.6% stage IIIB. One hundred forty-seven (72.4%) of 203 patients were randomly assigned to docetaxel (n = 73) or observation (n = 74). Grade 3 to 5 toxicities during docetaxel included febrile neutropenia (10.9%) and pneumonitis (9.6%); 28.8% of patients were hospitalized during docetaxel (v 8.1% in observation arm), and 5.5% died as a result of docetaxel. The MST for all patients (n = 203) was 21.7 months; MST was 21.2 months for docetaxel arm compared with 23.2 months for observation arm (P = .883). CONCLUSION: Consolidation docetaxel after PE/XRT results in increased toxicities but does not further improve survival compared with PE/XRT alone in patients with stage III inoperable NSCLC.

ABSTRACT

BACKGROUND: Ovarian tumors frequently express c-Kit and/or platelet-derived growth factor receptors (PDGFRs). Imatinib mesylate blocks the growth of ovarian cancer cells in vitro and may enhance the activity of chemotherapy. This study was conducted to determine the activity of imatinib in combination with docetaxel in patients with recurrent, platinum-resistant epithelial ovarian cancer (EOC). METHODS: Eligible patients had recurrent, platinum-resistant, or refractory EOC that expressed PDGFRalpha or c-kit, as determined by immunohistochemistry. Imatinib mesylate at a dose of 600 mg orally once daily was administered continuously with docetaxel at a dose of 30 mg/m(2) given intravenously once weekly in Weeks 1 through 4 of every 6-week cycle. The primary endpoint was objective response rate (ORR) as assessed by the Response Evaluation Criteria in Solid Tumors (RECIST). RESULTS: Thirty-four patients were screened for PDGFRalpha and c-kit expression to enroll 23 patients between December 2003 and October 2005. Four patients had c-kit-positive/PDGFR-negative tumors, 11 patients had PDGFR-positive/c-kit-negative tumors, and 8 patients had c-kit-positive/PDGFR-positive tumors. The median patient age was 56 years (range, 33-76 years). Patients had received a median of 3 prior treatments. The ORR was 21.7% and included 1 complete and 4 partial responses. An additional 3 patients had stable disease for more than 4 months. Expression of PDGFR, c-kit, phosphatase and tensin homolog (PTEN), and phosphorylated protein kinase B (Akt) did not predict response to therapy. The most common adverse events encountered were fatigue (83%), nausea (74%), diarrhea (61%), anorexia (52%), and edema (65%), and the majority of those events were graded as grade 1 or 2. CONCLUSIONS: The combination imatinib and docetaxel was tolerated in patients with heavily pretreated EOC that expressed c-kit or PDGFRalpha. Few patients had sustained responses or stable disease.

ABSTRACT

BACKGROUND: Gefitinib, an inhibitor of the epidermal growth factor receptor (EGFR) pathway, has single agent activity in non-small cell lung cancer (NSCLC). Preclinical studies demonstrate significant interactions between the EGFR and cyclooxygenase 2 (COX-2) pathways and that simultaneous inhibition may have benefits over EGFR inhibitors alone. ELIGIBILITY CRITERIA: chemotherapy-naive, stage IIIb (with pleural effusion) or IV NSCLC, Eastern Cooperative Oncology Group Performance Status (PS) 0-1. Patients were treated with gefitinib 250 mg po daily plus celecoxib 400 mg po every 12 hours. Cycles consisted of 21-day treatment and continued until unacceptable toxicity or progression of disease. The primary objective was to evaluate the overall response rate; secondary objectives included estimation of progression free survival, overall survival, and to assess the toxicity of this regimen. RESULTS: From January 2004 to November 2004, 31 patients were enrolled: male/female 13/18; median age 70 years (range, 19-93); 68% had adenocarcinoma; Eastern Cooperative Oncology Group PS 0/1 13/18; stage IIIb/IV 2/29. Two patients died of interstitial lung disease due to treatment. There were three additional deaths during treatment that were not considered treatment related. Two additional patients discontinued treatment due to adverse events (elevated liver enzymes). Select grade 3/4 toxicities included: pneumonitis (3%), hepatic (7%), diarrhea (7%), and skin (3%). Response rate was 16% (95% CI, 5-34%), median progression free survival and overall survival were 3.2 (95% CI, 2.7-5.7 months) and 7.0 months (95% CI, 3.7-14.2 months), respectively. All responders were females with adenocarcinoma, two were remote or never smokers and three were former smokers. CONCLUSION: Gefitinib plus celecoxib in an unselected population of chemotherapy naive patients with advanced NSCLC and a PS of 0-1 has a lower response rate and overall efficacy compared with historical controls of combination chemotherapy.
