How Many Cancer Clinical Trials Can a Clinical Research Coordinator Manage? The Clinical Research Coordinator Workload Assessment Tool.

PURPOSE: Cancer clinical trials (CTs) are now more complex than ever before and require dedicated personnel (clinical research coordinators [CRCs]) to perform regulatory and administrative activities and protocol- and patient-related procedures. We developed a simple tool to measure the workload (WL) of CRCs involved in cancer research and to estimate personnel requirements within a Clinical Trial Center. METHODS: A literature review and 2-month period in which CRCs recorded their activities in a diary provided valuable information that led to the Istituto Scientifico Romagnolo per lo Studio e la Cura dei Tumori Workload Assessment Tool (IWAT) being divided into three sections: Protocol, On-Treatment Patients, and Follow-Up Patients. Twelve full-time senior CRCs from three sites of the Network measured their monthly WL for 30 months to evaluate IWAT reproducibility and accuracy. RESULTS: The IWAT proved to be a user-friendly tool (3-6 minutes required for each CT), with high reproducibility (interobserver reproducibility ranged from 82% to 100% for each IWAT item). In December 2017, the Network had 185 ongoing CTs, with a median of 2.5 active centers for each CT. On the basis of 448 total IWAT measures by CRCs, the majority of trials were academic (57%) or dealt with advanced disease (77%). The median IWAT WL score for each study was 20.98 ± 22.90 (range, 2-188) and 475 ± 229 (range, 150 [junior staff] - 930 [extreme heavy WL]) for each CRC. On the basis of our experience, a monthly WL score of 500-600 was considered an appropriate value for a full-time CRC. CONCLUSION: The IWAT could prove useful in evaluating CT complexity, estimating appropriate CRC WLs, and defining personnel requirements. Independent validation by other CRCs working in different organizational contexts and in different countries is needed.

Randomized phase II study with two gemcitabine- and docetaxel-based combinations as first-line chemotherapy for metastatic non-small cell lung cancer.

BACKGROUND: Docetaxel and gemcitabine combinations have proven active for the treatment of non-small cell lung cancer (NSCLC). The aim of the present study was to evaluate and compare two treatment schedules, one based on our own preclinical data and the other selected from the literature. METHODS: Patients with stage IV NSCLC and at least one bidimensionally-measurable lesion were eligible. Adequate bone marrow reserve, normal hepatic and renal function, and an ECOG performance status of 0 to 2 were required. No prior chemotherapy was permitted. Patients were randomized to arm A (docetaxel 70 mg/m2 on day 1 and gemcitabine 900 mg/m2 on days 3-8, every 3 weeks) or B (gemcitabine 900 mg/m2 on days 1 and 8, and docetaxel 70 mg/m2 on day 8, every 3 weeks). RESULTS: The objective response rate was 20% (95% CI:10.0-35.9) and 18% (95% CI:8.6-33.9) in arms A and B, respectively. Disease control rates were very similar (54% in arm A and 53% in arm B). No differences were noted in median survival (32 vs. 33 weeks) or 1-year survival (33% vs. 35%). Toxicity was mild in both treatment arms. CONCLUSION: Our results highlighted acceptable activity and survival outcomes for both experimental and empirical schedules as first-line treatment of NSCLC, suggesting the potential usefulness of drug sequencing based on preclinical models. TRIAL REGISTRATION NUMBER: IOR 162 02.

Phase II study of oxaliplatin and gemcitabine salvage chemotherapy in patients with cisplatin-refractory nonseminomatous germ cell tumor.

OBJECTIVE: Cisplatin-refractory germ cell tumors (GCTs) represent a subset of germinal neoplasms with a poor prognosis. Conventional-dose chemotherapy induces objective response in 10-20% of these patients with rare durable complete remissions. We investigated the activity and tolerance of a chemotherapeutic regimen with oxaliplatin and gemcitabine. PATIENTS AND METHODS: Treatment consisted of oxaliplatin 130 mg/m(2) day 1, and gemcitabine 1,250 mg/m(2), days 1 and 8, every three weeks. RESULTS: Eighteen patients were enrolled and were assessable for response and toxicity. Primary site was testis in twelve cases, retroperitoneum in four, and mediastinum in two. Seven patients (39%) were cisplatin-refractory, while eleven (61%) absolutely cisplatin-refractory. A median of three cycles (range, 1-6) per patient were given. One patient achieved a clinical complete remission, one a partial remission with negative marker in whom complete surgical resection of residual masses yielded mature teratoma only, and one a partial remission with positive marker in whom complete surgical resection of residual masses yielded viable tumor cells. These three cases were characterized by testicular primary embryonal carcinoma. They remained disease-free at 44+, 20+, and 18+ months of follow-up. CONCLUSION: The oxaliplatin-gemcitabine combination is a safe and active standard-dose regimen for patients with cisplatin-refractory testicular primary GCT.

Feasibility of radiotherapy after high-dose dense chemotherapy with epirubicin, preceded by dexrazoxane, and paclitaxel for patients with high-risk Stage II-III breast cancer.

PURPOSE: To verify the feasibility of, and quantify the risk of, pneumonitis from locoregional radiotherapy (RT) after high-dose dense chemotherapy with epirubicin and paclitaxel with peripheral blood progenitor cell support in patients with high-risk Stage II-III breast cancer. METHODS AND MATERIALS: Treatment consisted of a mobilizing course of epirubicin 150 mg/m2, preceded by dexrazoxane (Day 1), paclitaxel 175 mg/m2 (Day 2), and filgrastim; followed by three courses of epirubicin 150 mg/m2, preceded by dexrazoxane (Day 1), paclitaxel 400 mg/m2 (Day 2), and peripheral blood progenitor cell support and filgrastim, every 16-19 days. After chemotherapy, patients were treated with locoregional RT, which included the whole breast or the chest wall, axilla, and supraclavicular area. RESULTS: Overall, 64 of 69 patients were evaluable. The interval between the end of chemotherapy and the initiation of RT was at least 1.5-2 months (mean 2). No treatment-related death was reported. After a median follow-up of 27 months from RT (range 5-77 months), neither clinically relevant radiation pneumonitis nor congestive heart failure had been reported. Minor and transitory lung and cardiac toxicities were observed. CONCLUSION: Sequential high doses of epirubicin, preceded by dexrazoxane, and paclitaxel did not adversely affect the tolerability of locoregional RT in breast cancer patients. The risk of pneumonitis was not affected by the use of sequential paclitaxel with an interval of at least 1.5-2 months between the end of chemotherapy and the initiation of RT. Long-term follow-up is needed to define the risk of cardiotoxicity in these patients.

Phase II study of gemcitabine, doxorubicin and paclitaxel (GAT) as first-line chemotherapy for metastatic breast cancer: a translational research experience.

BACKGROUND: Patients with metastatic breast cancer are frequently treated with anthracyclines and taxanes, which are among the most active agents in this disease. Gemcitabine is an interesting candidate for a three-drug combination because of its different mechanism of action and non-overlapping toxicity with respect to the other two drugs. We aimed to evaluate the activity and toxicity of the GAT (gemcitabine, doxorubicin and paclitaxel) regimen, derived from experimental preclinical studies, as first-line chemotherapy in patients with stage IIIB-IV breast cancer. METHODS: Patients with locally advanced or metastatic breast cancer and at least one bidimensionally measurable lesion were included in the present study. Adequate bone marrow reserve, normal cardiac, hepatic and renal function, and an ECOG performance status of 0 to 2 were required. Only prior adjuvant non anthracycline-based chemotherapy was permitted. Treatment consisted of doxorubicin 50 mg/m2 on day 1, paclitaxel 160 mg/m2 on day 2 and gemcitabine 800 mg/m2 on day 6, repeated every 21-28 days. RESULTS: Thirty-three consecutive breast cancer patients were enrolled onto the trial (7 stage IIIB and 26 stage IV). All patients were evaluable for toxicity and 29 were assessable for response. A total of 169 cycles were administered, with a median of 6 cycles per patient (range 1-8 cycles). Complete and partial responses were observed in 6.9% and 48.3% of patients, respectively, for an overall response rate of 55.2%. A response was reported in all metastatic sites, with a median duration of 16.4 months. Median time to progression and overall survival were 10.2 and 36.4 months, respectively. The most important toxicity was hematological, with grade III-IV neutropenia observed in 69% of patients, sometimes requiring the use of granulocyte colony-stimulating factor (27%). Non hematological toxicity was rare and mild. One patient died from sepsis during the first treatment cycle before the administration of gemcitabine. CONCLUSION: The strong synergism among the three drugs found in the preclinical setting was confirmed in terms of both clinical activity and hematological toxicity. Our results seem to indicate that the GAT regimen is effective in anthracycline-naïve metastatic breast cancer and provides a feasible chemotherapeutic option in this clinical setting.

Bolus fluorouracil and leucovorin with oxaliplatin as first-line treatment in metastatic colorectal cancer.

PURPOSE: A phase II trial investigated the activity and toxicity of a bolus administration schedule of oxaliplatin, fluorouracil (5-FU), and leucovorin (LV) therapy in patients with untreated advanced colorectal cancer. PATIENTS AND METHODS: Forty-five patients in this multicenter, open, nonrandomized study received oxaliplatin 130 mg/m(2) on the first day of each course and 5-FU and LV 350 mg/m(2) and 20 mg/m(2), respectively, as a daily bolus for 5 days, every 21 days, for a maximum of six courses. RESULTS: Partial responses occurred in 18 patients, giving an intent-to-treat response rate of 40.0%. Median time to response was 12.7 weeks; median duration of response was 18.4 weeks. Median progression-free survival was 5.9 months; median survival was 14 months. The independent prognostic factors for improved overall survival were good performance status and negative carcino-embryonic antigen blood level. Incidences of adverse effects were reduced after the 5-FU dose was reduced to 300 mg/m(2). Reversible neurologic toxicity occurred in 44.4% of patients. CONCLUSION: Bolus administration of oxaliplatin, 5-FU, and LV as first-line therapy for untreated advanced colorectal cancer is efficacious and safe. In addition to a more favorable safety profile, the 300 mg/m(2) dosage offered improved dose-intensity compared with the initial dosage.
