Transforming the Early Drug Development Paradigm at the National Cancer Institute: The Formation of NCI's Experimental Therapeutics Clinical Trials Network (ETCTN).

Early drug development for cancer requires broad collaboration and skilled clinical investigators to enable enrollment of patients whose tumors have defined molecular profiles. To respond to these challenges, the National Cancer Institute (NCI) transformed its 60-year-old early-phase drug development program in 2014 into the Experimental Therapeutics Clinical Trials Network (ETCTN). The ETCTN is a consolidated, national network of 40+ academic institutions responsible for conducting more than 100 early-phase clinical trials. It promotes team science coordinated among basic, translational, and clinical investigators, emphasizing the inclusion of early career trialists. This perspective provides a brief overview of the ETCTN, summarizes its successes and challenges over its first grant funding cycle, and discusses the program's future directions. Measures indicated strong connectivity across the institutions, significant increases in investigator approval of the ETCTN scientific portfolio from years 1 to 4, and substantial research activity over 5 years, with 334 letters of intent submitted, 102 trials activated, and 3,570 patients accrued. The ETCTN's successful adoption relied heavily on the inclusion of senior investigators who have long-standing interactions with the NCI and a willingness to participate in a team science approach and to mentor early career investigators. In addition, NCI invested substantial resources in a centralized infrastructure to conduct trials and to support the inclusion of biomarkers in its studies. The ETCTN provides evidence that a collaborative national clinical trial network for early drug development is feasible and can address the demands of precision medicine approaches to oncologic clinical trials.

Establishment of a research pharmacy to support Ebola clinical research in Liberia.

OBJECTIVE: This article describes the establishment of a research pharmacy to support the Partnership for Research on Ebola Vaccines in Liberia (PREVAIL) vaccine study for Ebola virus disease. SETTING: This article describes the establishment of the pharmacy element to support the overall research program during an Ebola outbreak in Monrovia, Liberia, in 2014 and 2015. PRACTICE INNOVATION: The need for the rapid establishment of infrastructure to support the Liberia-United States joint clinical research partnership in response to the emerging Ebola virus disease provided the opportunity for collaboration among Liberian and U.S. pharmacists. PRACTICE DESCRIPTION: Resource austere and research naïve. EVALUATION: Research pharmacy prepared and randomized 1500 vaccinations in support of PREVAIL. RESULTS: Experiences of the Liberian and U.S. pharmacists involved in the program are described. CONCLUSION: The partnership was successful in the conduct of the study. More importantly, the capacity for Liberian pharmacists to support clinical research was established. In addition, the U.S. team learned several important lessons that will help prepare them for responding to research needs in future infectious disease outbreaks.

Stakeholder perspectives on implementing the National Cancer Institute's patient-reported outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE).

The National Cancer Institute (NCI) is developing a patient-reported version of its Common Terminology Criteria for Adverse Events, called the "PRO-CTCAE." The PRO-CTCAE consists of a library of patient-reported items which can be administered in clinical trials to directly capture the patient experience of adverse events during cancer treatment, as well as a software platform for administering these items via computer or telephone. In order to better understand the impressions of stakeholders involved in cancer clinical research about the potential value of the PRO-CTCAE approach to capturing adverse event information in clinical research, as well as their perspectives about barriers and strategies for implementing the PRO-CTCAE in NCI-sponsored cancer trials, a survey was conducted. A survey including structured and open-ended questions was developed to elicit perceptions about the use of patient-reported outcomes (PROs) for adverse event reporting, and to explore logistical considerations for implementing the PRO-CTCAE in cancer trials. The survey was distributed electronically and by paper to a convenience sample of leadership and committee members in the NCI's cooperative group network, including principal investigators, clinical investigators, research nurses, data managers, patient advocates, and representatives of the NCI and Food and Drug Administration. Between October, 2008 through February, 2009, 727 surveys were collected. Most respondents (93%) agreed that patient reporting of adverse symptoms would be useful for improving understanding of the patient experience with treatment in cancer trials, and 88%, 80%, and 76%, respectively, endorsed that administration of PRO-CTCAE items in clinical trials would improve the completeness, accuracy, and efficiency of symptom data collection. More than three fourths believed that patient reports would be useful for informing treatment dose modifications and towards FDA regulatory evaluation of drugs. Eighty-eight percent felt that patients in clinical trials would be willing to self-report adverse symptoms at clinic visits via computer, and 68% felt patients would self-report weekly from home via the internet or an automated telephone system. Lack of computers and limited space and personnel were seen as potential barriers to in-clinic self-reporting, but these were judged to be surmountable with adequate funding. The PRO-CTCAE items and software are viewed by a majority of survey respondents as a means to improve adverse event data quality and comprehensiveness, enhance clinical decision-making, and foster patient-clinician communication. Research is ongoing to assess the measurement properties and feasibility of implementing this measure in cancer clinical trials.

The challenges of clinical trials for adolescents and young adults with cancer.

In the United States, Europe, and Australia, and probably all countries of the world, older adolescents and young adults with cancer are under-represented in clinical trials of therapies that could improve their outcome. Simultaneously, the survival and mortality rates in these patients have mirrored the clinical trial accrual pattern, with little improvement compared with younger and older patients. This suggests that the relative lack of participation of adolescent and young adult patients in clinical trials has lessened their chances for as good an outcome as that enjoyed by patients in other age groups. Thus, increased availability of and participation in clinical trials is of paramount important if the current deficits in outcome in young adults and older adolescents are to be eliminated. Regardless of whether there is a causal relationship, the impact of low clinical trial activity on furthering our scientific knowledge and management of cancer during adolescence and early adulthood is detrimental.

Adolescents and young adults with cancer: the scope of the problem and criticality of clinical trials.

In the U.S., older adolescents and young adults with cancer have benefited less from therapeutic advances than did either younger or older patients. One factor that may explain this deficit is the relative lack of participation of patients in this age group on clinical trials of therapies that could improve their outcome. Comparisons were made of the participation of cancer patients on clinical trials in the U.S., as a function of patient age, with the change in national cancer mortality rate; and Surveillance, Epidemiology, End Results (SEER) cancer survival rate as a function of age. The participation rate in cancer treatment trials has been strikingly lower in 15-34-year-olds than in younger or older patients. The nadir has been apparent for both males and females in all of the major ethnic and racial groups. The national cancer mortality reduction and SEER survival improvement shows a similar age dependence. In the U.S., the age-dependence of cancer treatment trial participation, and of improvement in survival prolongation and cancer death rates, are correlated. Regardless of whether there is a causal relationship, the impact on the older adolescent and young adult U.S. population is substantial, adversely affecting the national cost of healthcare, the person-years of life lost, the loss of young people entering the job market, and the scientific knowledge and social implications of cancer during adolescence and early adulthood. National initiatives are underway to address these issues, with special emphasis on increasing the availability and access to clinical trials designed for older adolescents and young adults.

National survival trends of young adults with sarcoma: lack of progress is associated with lack of clinical trial participation.

BACKGROUND: Young adults with cancer in the U.S. have had less improvement in survival than either younger patients or older patients. The authors attempted to determine whether similar deficits have occurred in young adults with sarcomas and, if so, then why. METHODS: In 38,144 young adults with sarcoma who were diagnosed during 1975-1998 and were followed by the National Cancer Institute's (NCI) Surveillance, Epidemiology, and End Results Program, the average annual percent change in 5-year survival was derived as a function of patient age. National sarcoma treatment trial data were obtained on 3242 patients who were entered onto NCI-sponsored trials during 1997-2002. RESULTS: 1) For patients with bone and soft-tissue sarcomas, except Kaposi sarcoma (KS), the least survival improvement occurred between age 15 years and age 45 years. For patients with KS, the pattern was reversed, with the greatest survival increase occurring among patients ages 30-44 years. 2) The lowest participation rate in NCI-sponsored sarcoma treatment trials occurred in patients ages 20-44 years. For patients with KS, the highest accrual rate occurred in patients ages 35-44 years. 3) The age-dependent survival improvement and clinical-trial accrual patterns were correlated directly (soft-tissue sarcomas, P < 0.005; bone sarcomas, P < 0.05; KS, P = 0.06), regardless of whether the accrual profile demonstrated a decline or a peak (KS) during early adulthood. CONCLUSIONS: The lack of survival prolongation in patients age 15-44 years in the U.S. with non-KS sarcomas may have been a result of their relative lack of participation in clinical trials. If this is true, then reversing the shortfall in survival among young adults with sarcomas, as was accomplished among patients with KS, should benefit from increased clinical trial availability, access, and participation.

Participation of patients 65 years of age or older in cancer clinical trials.

PURPOSE: Although 61% of new cases of cancer occur among the elderly, recent studies indicate that the elderly comprise only 25% of participants in cancer clinical trials. Further investigation into the reasons for low elderly participation is warranted. Our objective was to evaluate the participation of the elderly in clinical trials sponsored by the National Cancer Institute (NCI) and assess the impact of protocol exclusion criteria on elderly participation. PATIENTS AND METHODS: We conducted a retrospective analysis using NCI data, analyzing patient and trial characteristics for 59,300 patients enrolled onto 495 NCI-sponsored, cooperative group trials, active from 1997 through 2000. Our main outcome measure was the proportion of elderly patients enrolled onto cancer clinical trials compared with the proportion of incident cancer patients who are elderly. RESULTS: Overall, 32% of participants in phase II and III clinical trials were elderly, compared with 61% of patients with incident cancers in the United States who are elderly. The degree of underrepresentation was more pronounced in trials for early-stage cancers than in trials for late-stage cancers (P <.001). Furthermore, protocol exclusion criteria on the basis of organ-system abnormalities and functional status limitations were associated with lower elderly participation. We estimate that if protocol exclusions were relaxed, elderly participation in cancer trials would be 60%. CONCLUSION: The elderly are underrepresented in cancer clinical trials relative to their disease burden. Older patients are more likely to have medical histories that make them ineligible for clinical trials because of protocol exclusions. Insurance coverage for clinical trials is one step toward improvement of elderly access to clinical trials. Without a change in study design or requirements, this step may not be sufficient.

2001 anthrax crisis in Washington, D.C.: clinic for persons exposed to contaminated mail.

An anthrax prophylaxis clinic is described. In October 2001, four workers from the U.S. Postal Service's Brentwood facility in Washington, D.C., were hospitalized with inhalational anthrax; many others may have been exposed to anthrax spores. U.S. Public Health Service (USPHS) teams were deployed to establish an anthrax prophylaxis clinic that would provide education and medication to workers and people who visited the mail facility. The temporary clinic was set up at D.C. General Hospital and was staffed primarily by health care professionals from USPHS. The protocol at the clinic involved three major phases. Phase 1 consisted of gathering information from the patient and distributing educational materials. Phase 2 involved presentations by a physician and a pharmacist concerning anthrax, followed by a question-and-answer session. In phase 3, a pharmacist selected the most appropriate prophylactic agent, dispensed the medication, counseled the patient, and referred patients with flu-like symptoms or skin lesions to a physician. Two floor plans were used to maximize the number of patients seen per hour without jeopardizing patient care. The clinic operated 14 hours a day for 14 days. The 136-member health care team included 52 pharmacists, and medication was dispensed to more than 18,000 patients. The clinic may serve as a model for pharmacists and other professionals in designing and implementing disaster plans. A multidisciplinary team established and operated a clinic to treat persons who may have been exposed to anthrax through contaminated mail.

2001 anthrax crisis in Washington, D.C.: pharmacists' role in screening patients and selecting prophylaxis.

Pharmacists' development and use of a worksheet facilitating their rapid selection of patient-appropriate prophylactic antimicrobials in an anthrax clinic is described. A clinic housed at D.C. General Hospital, in Washington, D.C., treated most of the people--many of them postal workers--who may have been exposed to anthrax in that city during the 2001 anthrax crisis. A form was needed to assist pharmacists in the rapid selection of prophylactic antimicrobials and in patient education and counseling. A team of pharmacists collaborated on the development of a form tailored to the clinical and logistical needs of the operation. The questions on the form were based largely on the two antianthrax agents most likely to be used, ciprofloxacin and doxycycline, and were designed to identify the circumstances that would most frequently require a medication change or a modification of patient education. Yes-or-no check boxes allowed pertinent data to be captured most efficiently. A positive response to any question triggered a personal interview and assessment by a pharmacist. A treatment algorithm was also developed to ensure consistent pharmacist selection of agents in the face of potentially changing policies and staff. The worksheet questions sought to establish treatment objectives, document allergies and concomitant therapies, and identify patients who were pregnant or lactating. Pharmacists developed a patient-screening worksheet that helped determine their choice of treatment for people who may have been exposed to anthrax in Washington, D.C., during the 2001 anthrax crisis.
