Participants' responsibilities in clinical research.

Discussions on the ethics and regulation of clinical research have a great deal to say about the responsibilities of investigators, sponsors, research institutions and institutional review boards, but very little about the responsibilities of research participants. In this article, we discuss the responsibilities of participants in clinical research. We argue that competent adult participants are responsible for complying with study requirements and fulfilling other obligations they undertake when they make an informed choice to enroll in a study. These responsibilities are based on duties related to promise-keeping, avoiding harm to one's self or others, beneficence and reciprocity. Investigators and research staff should inform participants about their responsibilities during the consent process, and should stress the importance of fulfilling study requirements. They should address any impediments to compliance, and they may provide participants with financial incentives for meeting study requirements. In very rare cases, coercive measures may be justified to prevent immanent harm to others resulting from non-compliance with study requirements.

Teaching principles of translational science to a broad scientific audience using a case study approach: A pilot course from the National Center for Advancing Translational Sciences.

There are numerous examples of translational science innovations addressing challenges in the translational process, accelerating progress along the translational spectrum, and generating solutions relevant to a wide range of human health needs. Examining these successes through an education lens can identify core principles and effective practices that lead to successful translational outcomes. The National Center for Advancing Translational Sciences (NCATS) is identifying and teaching these core principles and practices to a broad audience via online courses in translational science which teach from case studies of NCATS-led or supported research initiatives. In this paper, we share our approach to the design of these courses and offer a detailed description of our initial course, which focused on a preclinical drug discovery and development project spanning academic and government settings. Course participants were from a variety of career stages and institutions. Participants rated the course high in overall value to them and in providing a unique window into the translational science process. We share our model for course development as well as initial findings from the course evaluation with the goal of continuing to stimulate development of novel education activities teaching foundational principles in translational science to a broad audience.

Modernizing Clinical Trial Eligibility Criteria: Recommendations of the ASCO-Friends of Cancer Research Washout Period and Concomitant Medication Work Group.

PURPOSE: Washout periods and concomitant medication exclusions are common in cancer clinical trial protocols. These exclusion criteria are often applied inconsistently and without evidence to justify their use. The authors sought to determine how washout period and concomitant medication allowances can be broadened to speed trial enrollment and improve the generalizability of trial data to a larger oncology practice population without compromising the safety of trial participants. EXPERIMENTAL DESIGN: A multistakeholder working group was convened to define problems associated with excessively long washout periods and exclusion of patients due to concomitant medications. The group performed a literature search and evaluated study data from the Pancreatic Cancer Action Network (PanCAN), Emory University School of Medicine (Atlanta, GA), and the FDA to understand recent approaches to these eligibility criteria. The group convened to develop consensus recommendations for broadened eligibility criteria. RESULTS: The data analysis found that exclusion criteria based on washout periods and concomitant medications are frequently inconsistent and lack scientific rationale. Scientific rationale for appropriate eligibility criteria are presented in the article; for washout periods, rationale is presented by treatment type. CONCLUSIONS: Arbitrary or blanket washout and concomitant medication exclusions should be eliminated. Where there is evidence to support them, clinically relevant washout periods and concomitant medication-related eligibility criteria may be included.See related commentary by Giantonio, p. 2369.

A national patient navigator training program.

Patient Navigation is an intervention aimed at addressing cancer health disparities by eliminating barriers to diagnosis, treatment, and services. Three major patient navigation (PN) programs (The National Cancer Institute, The American Cancer Society &The Center for Medicare and Medicaid Services) are underway to address the needs of medically underserved cancer patients. There has not been national training with a defined curriculum for patient navigators (PNs). Curriculum for training the PNs was created by experts from the three programs. The efficacy of training was evaluated using a pre- and posttest. The data show that overall the posttest scores improved from the pretest. In addition, having a high school education or greater or having more years of work experience were significantly related to improvements on the posttest. The first successful standardized national training program was attended by 116 PNs representing 85 cities with the goal to reduce health disparities for medically underserved.

The Oncology Clinical Research Nurse Study Co-Ordinator: Past, Present, and Future.

Clinical research nursing is a specialty practice that has evolved over the past century. Clinical research nurses (CRNs) work directly (e.g., direct care provider and advance clinician) or indirectly (e.g., manager, educator, and study co-ordinator) to support clinic research. For more than 50 years, oncology nurses have contributed to the body of evidence describing and validating the responsibilities and importance of the nurse in clinical research, especially the study co-ordinator role. This article will focus on the CRN study co-ordinator role in oncology clinical trials highlighting the historical evolution of the role, the contributions of dedicated members of the Oncology Nursing Society, and the future landscape of clinical research nursing through the International Association of CRNs.

Clinical Trials and the Role of the Oncology Clinical Trials Nurse.

Clinical trials are paramount to improving human health. New trial designs and informed consent issues are emerging as a result of genomic profiling and the development of molecularly targeted agents. Many groups and individuals are responsible for ensuring the protection of research participants and the quality of the data produced. The specialty role of the clinical trials nurse (CTN) is critical to clinical trials. Oncology CTNs have competencies that can help guide their practice; however, not all oncology clinical trials are supervised by a nurse. Using the process of engagement, one organization has restructured oncology CTNs under a nurse-supervised model.

Systematic collection of patient reported outcome research data: A checklist for clinical research professionals.

Understanding the human experience is no longer an outcome explored strictly by social and behavioral researchers. Increasingly, biomedical researchers are also including patient reported outcomes (PROs) in their clinical research studies not only due to calls for increased patient engagement in research but also healthcare. Collecting PROs in clinical research studies offers a lens into the patient's unique perspective providing important information to industry sponsors and the FDA. Approximately 30% of trials include PROs as primary or secondary endpoints and a quarter of FDA new drug, device and biologic applications include PRO data to support labeling claims. In this paper PRO, represents any information obtained directly from the patient or their proxy, without interpretation by another individual to ascertain their health, evaluate symptoms or conditions and extends the reference of PRO, as defined by the FDA, to include other sources such as patient diaries. Consumers and clinicians consistently report that PRO data are valued, and can aide when deciding between treatment options; therefore an integral part of clinical research. However, little guidance exists for clinical research professionals (CRPs) responsible for collecting PRO data on the best practices to ensure quality data collection so that an accurate assessment of the patient's view is collected. Therefore the purpose of this work was to develop and validate a checklist to guide quality collection of PRO data. The checklist synthesizes best practices from published literature and expert opinions addressing practical and methodological challenges CRPs often encounter when collecting PRO data in research settings.

Initial clinical trial of oral TAC-101, a novel retinoic acid receptor-alpha selective retinoid, in patients with advanced cancer.

PURPOSE: The goals of this study were to determine the safety, toxicity, and pharmacokinetics of TAC-101, a novel synthetic retinoic acid receptor-alpha (RAR-alpha) selective retinoid, in patients with advanced cancer. PATIENTS AND METHODS: Twenty-nine patients at two centers received oral TAC-101 at doses ranging from 12 to 34 mg/m(2)/d. Pharmacokinetic sampling was performed on days 1 and 28. RESULTS: The most frequent toxicities were myalgia/arthralgia, fatigue, and triglyceridemia. No dose-limiting toxicities were observed within the first 28 days up to 28 mg/m(2). However, seven of 21 patients experienced venous thromboembolic events (VTEs) during TAC-101 treatment. Eight additional patients who received 34 mg/m(2) were treated after a hypercoagulable work-up to exclude potential risk factors for VTE, and two of eight patients subsequently experienced VTEs. The maximum tolerated dose was exceeded at 34 mg/m(2)/d within the first 28 days, with one grade 3 hypertriglyceridemia, two grade 3 myalgia/arthralgia, and one grade 3 fatigue. One patient with advanced non-small-cell lung cancer had a complete response. No other responses were observed. No autoinduction of metabolism was observed with dosing over 28 days. CONCLUSION: This is the first human clinical study with TAC-101, a RAR-alpha selective retinoid. Musculoskeletal toxicity and hypertriglyceridemia were observed characteristics of previously studied retinoids. The recommended phase II dose is 24 mg/m(2) with this treatment schedule. Alternative treatment schedules and prospective evaluation of thrombotic risk will be investigated in subsequent studies.

A phase I study of oral BMS-275291, a novel nonhydroxamate sheddase-sparing matrix metalloproteinase inhibitor, in patients with advanced or metastatic cancer.

PURPOSE: BMS-275291 is a novel broad-spectrum inhibitor of matrix metalloproteinase (MMPs) rationally designed to spare a class of closely related metalloproteinases known as sheddases. Inadvertent sheddase inhibition is hypothesized to play a role in the dose-limiting joint toxicities occurring with hydroxamate-based MMP inhibitors. This trial was conducted to establish the recommended phase II dose; determine safety, toxicity, and pharmacokinetics of BMS-275291; and to assess potential markers of sheddase activity [tumor necrosis factor-alpha (TNFalpha) release and TNFalpha-RII shedding]. EXPERIMENTAL DESIGN: This was an open label, single arm, phase I study conducted at two centers. Patients with advanced or metastatic cancer were treated with once-daily oral BMS-275291 at doses escalating from 600 to 2400 mg/day. Six to eight patients/dose level were to be studied with the recommended phase II dose level expanded to a total of 15 patients. Pharmacokinetic sampling was performed on days 1, 15, and 29 at 0, 0.5, 1, 2, 4, 6, 8, and 24 h after dosing. Radiological tumor assessment was performed every 8 weeks. RESULTS: Forty-four evaluable patients were enrolled in this study with the most frequent tumor types being colorectal cancer and non-small cell lung cancer. Dose limiting toxicities were observed at 600 mg/day (one of eight patients with grade 3 transaminitis) and at 1200 mg/day (1 of 15 patients with grade 3 rash and grade 4 shortness of breath), both in the context of predisposing conditions. No dose-limiting toxicities occurred at 900, 1800, or 2400 mg/day. The most frequent adverse events considered possibly, probably, or definitely drug-related were joint toxicity (myalgia/arthralgia), rash, fatigue, headache, nausea, and taste change, all of which were mild, grade 1, grade 2, and not dose-limiting. No objective tumor responses were observed. Twelve of forty-four patients received treatment for 4+ months, six for 8+ months, three for >1 year. Desired trough levels of parent BMS-275291 were maintained with once daily dosing. The mean plasma concentration of parent BMS-275291 at trough exceeded the calculated in vitro IC(80) value for MMP-2 and IC(90) value for MMP-9 at the recommended phase II dose of 1200 mg/day. No major changes in serum concentrations of sheddase enzymatic products, TNFalpha or TNFalpha-RII, were observed. CONCLUSIONS: BMS-275291 is a nonhydroxamate MMP inhibitor with a novel mercaptoacyl zinc-binding group. In this study, plasma concentrations of BMS-275291 continuously exceeded in vitro MMP IC(50) values without dose-limiting joint toxicity. In this refractory patient population, a suggestion of disease stabilization was observed in 12 patients. On the basis of preclinical, clinical, and pharmacokinetic data, the recommended phase II dose for future study is 1200 mg/day.

Phase I study of prolonged infusion Bryostatin-1 in patients with advanced malignancies.

PURPOSE: Bryostatin-1 is a compound known to inhibit protein kinase C expression. Clinical trials have focused on administration schedules ranging from 1 hour to 72 hour infusions. Preclinical data suggest that the down regulation of the target PKC occurs only as long as the drug is being infused. Therefore we performed a phase 1 clinical trial to determine the safety and recommended dose of prolonged infusion Bryostatin-1. EXPERIMENTAL DESIGN: Patients with advanced metastatic cancer were enrolled in this traditional phase 1 clinical trial utilizing prolonged infusion Bryostatin-1. The administration of Bryostatin-1 was initially begun at 96 hours and extended to 14 days. Doses were escalated using the 96 hour infusion time and then duration of infusion was increased. All patients underwent extensive sampling for determination of PKC levels as well as other key biologic end points. The determination of maximum tolerated dose and recommended phase two dose were based on toxicity. RESULTS: 38 patients were enrolled in the study. The recommended phase two doses were 24 mcg/m2 over five days, 16 mcg/m2 over six days and 8 mcg/m2 over 14 days. At the higher dose levels we demonstrated consistent down regulation of PKC-alpha. This was not observed at the low dose level. Toxicities were limited to myalgias and fatigue and were dose-related. The results of downstream signaling effects were less clear. MMP expression was not altered by treatment with Bryostatin-1. Only limited evidence for alterations in PKC activity as measured by expression of phosphorylated MAPK was observed. No objective responses were observed with five patients having prolonged stabilization of disease. CONCLUSIONS: Bryostatin-1 is safely administered over prolonged infusion schedules. There appears to be a dose response for PKC inhibition. Bryostatin-1 is a complicated compound as is the target PKC and its related signaling pathways. There is only limited clinical activity with this compound as a single agent; future studies should focus on combinations with other cytotoxics or targeted therapies.

Clinical research education: perspectives of nurses, employers, and educators.

The aim of this study was to understand the current environment around clinical research relating to nursing education and practice. This descriptive study analyzed data from 33 in-depth interviews with faculty members, nurse executives, staff development directors, and practicing nurses, as well as an online interactive brainstorming session with 28 deans of schools of nursing (or their designee). Patterns and themes that emerged within each group were identified and analyzed in relation to study objectives. Central themes emerged around participants' knowledge and attitudes about clinical research education for baccalaureate nursing students, factors enhancing or inhibiting inclusion of clinical research content in baccalaureate nursing programs, and professional roles nursing students could expect to assume after graduation. Although the participants agreed that mastery of clinical research knowledge and related skills is important, there was no agreement whether nurses should receive this education and training in baccalaureate programs or in staff development.

Romidepsin: a new drug for the treatment of cutaneous T-cell lymphoma.

Patients with cutaneous T-cell lymphoma (CTCL) have a rare, disfiguring, and life-threatening subtype of non-Hodgkin lymphoma primarily localized to the skin. Their immune systems are altered and their skin is compromised. In addition, they are highly prone to infections-the most common cause of death in patients with this disease. Patients presenting with early-stage disease involvement typically are treated with topical therapies; patients with advanced-stage and recurrent disease require systemic treatment. Specialized knowledge is required by oncology healthcare providers to manage the wide array of symptoms experienced by these patients as a part of the natural course of this disease. A new drug, romidepsin, approved by the U.S. Food and Drug Administration, is indicated in the treatment of relapsed CTCL. The authors discuss use of romidepsin in the context of CTCL and the information needed to safely administer romidepsin and manage its side effects.

The Center for Cancer Research Brown Bag Lunch sessions: the first year.

The Brown Bag Lunch subcommittee of the Center for Cancer Research, National Cancer Institute, was developed to provide an informal supportive environment that would allow staff to discuss clinically focused topics and best practices, preview presentations for meetings, or both. The initial goal was to hold six sessions per year. This article describes the first year's experience of the Brown Bag Lunches, the barriers encountered (e.g., attendance) and potential solutions (e.g., increase advertising), goals for the second year, and tips for conducting this type of educational offering in other healthcare settings.
