Pilot StudiesNuts and Bolts Deborah Grady, MD, MPH Professor of Medicine Associate Dean for Clinical and Translational Research UCSF
Pilot Studies • Small studies aimed at helping you: • plan the best study possible • determine that the study can be done • get funding for your study • Distinguish from pre-testing of questionnaires or measurements • Phase I and phase II trials • phase I - determine toxicity • phase II - determine best dose
Why Do a Pilot Study? • Feasibility • determine if you can do it • Logistics • determine the fastest, easiest, most cost-effective way to do it • Sample size ?? • estimate rate in placebo group, effect size, variance • To convince funders you can do it
Feasibility • Feasibility of recruitment • obtain data on numbers eligible • survey centers, participants • measure time, expense of recruitment • Feasibility of interventions, measures • can overweight/obese persons perform the 8 yoga postures and practice at home? • will there be side effects? • can participants do 2-h GTT/other tests? • Feasibility of adherence and follow-up
Logistics and Cost • What staff are needed? • How long do visits take? • Where will participants park? • Can participants answer questionnaires while completing GGT? • How much will the trial cost?
Sample Size Estimates • To determine sample size for full-scale trial: • Rates of outcome in typical participants • Estimate of effect size • Variability of the main outcome • Some question validity of effect size estimates based on small studies
How Big Should Pilots Be? • “It depends” • Sample size estimates rarely useful • Traditions and guesses • Cancer phase I trials start with 3 • Pilots for feasibility often 5-20 • Pilots to estimate effect size can be large • Often depends on resources and time
Do Pilots Need Control Groups? • “It depends” • Phase I trials (maximum tolerable dose) • generally uncontrolled • Phase II trials (minimum effective dose) • generally controlled • Feasibility and logistics • controls generally not needed • Effect size/sample size estimates • controls helpful
Funding for Pilots • Local institution • Research Allocation Program (RAP) • Residency Training Program • CTSI • NIH R03, R21, U34, K awards • Other • disease foundations • pharmaceutical companies • mentors • Can sometimes be done without funding
IRB Approval for Pilots • Like any study, pilots involving people (or medical records) need IRB approval • Testing questionnaires, developing yoga postures, etc. that are devised and pre-tested with advisors and staff generally do not need IRB approval
Nuts and Bolts • Resources • Contracts • Budgets • Study team • Space • Recruitment • Start-up • Forms • Adherence and follow-up • Money Matters • Closeout
Funding Sources • Small trials • NIH - R03, R21, R01 • Specialty organizations/foundations • AHA, ACS, ACOG, ADA, etc • Foundations • Pharmaceutical, device companies • Large trials • NIH - R01, P01, U01 • VA, AHRQ, CDC, DOD • Pharmaceutical, device companies
UCSF Resources • Senior colleagues in your discipline • Experienced trialists and trial staff • CTSI BREAD • design • ethics • statistical issues • database development and management
Contracts • Required if trial supported by industry • Must be approved by UCSF Industry Contracts & company’s legal division • lots of puzzling legalese • you should understand and revise, esp. scope of work • best to start with UCSF template, revise and submit to company • Between UCSF Regents and company • signed by PI
Elements of a Contract • Scope of work • Timetable for deliverables • Budget and timing of payments • get a bolus up front • don’t link payment to deliverables out of your control • Ownership of data and publishing rights • Rules for breaking contract • Confidentiality, indemnification • Patents and inventions
Budgets • NIH-style (NIH, VA, AHRQ, CDC) • prepared far in advance • governed by strict rules • funds restricted to categories • permission for carry-over required • certain expenses not allowed • subject to government audit • Pharmaceutical company budgets • prepared just before trial starts • negotiable • much more flexible
Money Matters • Pre-award manager • help prepare budget and “face” pages • help with budget justification • make sure you follow rules/timelines • Post-award manager • pay salaries, buy equipment and supplies • monthly report of expenditures • projections over life of trial
Who is the Study Team? • Principle investigator • Project director/clinic coordinator • Recruiter • Data manager • Programmer/analyst • Statistician • Quality control supervisor • Administrative assistant • Financial/personnel manager
How to Hire the Study Team • Work with your department or unit personnel (HR) manager • write a job description • decide on job series, step, salary • post the job at UCSF and advertise • review resumes • interview • select
Where to Find the Study Team • Other studies • UCSF employees • Recent graduates, students • Friends and colleagues • Chronicle, web
Training the Study Team • Describe, emphasize and demonstrate the importance of: • following the protocol/operations manual • meeting recruitment goals • complete adherence and follow-up • full outcome ascertainment • maintaining participant safety and confidentiality • ethical conduct of research • Formal training and certification of staff
Operations Manual and Training Meeting • Purpose and design of the trial • Each measurement and visit procedure • methods • qualified personnel • calibration and testing • Completing and altering study forms • Data entry or submission • Safety and ethical issues • Certification and training of new staff
Team Leadership • Management training useful • You are responsible and the boss • Keep your staff happy • involvement in the science • salary, working conditions • level of responsibility • Set an example • Promote good staff interactions • Some staff should be fired
Space • Considerations • accessibility, parking • design and décor • privacy • clinical needs, special tests • safety measures • cost • CTSI CRCs • On-campus or medical space • Off campus rental
Recruitment • Hire an experienced recruiter • Provide adequate time and money • Monitor results • Make changes • different approaches • more centers • longer recruitment • change eligibility
Recruitment • Mailing • Targeted (age, gender, disease, etc) • UCSF Integrated Data Repository • Kaiser • DMV, HCFA, registries • Mass • DMV, Voter Registration, HCFA • Private companies • Email • Follow HIPPA and confidentiality rules
Recruiment • Referral from providers • Advertise • hospital, clinics, special sites, churches • radio, newspaper, TV, internet • celebrities, leaders follow HIPPA and confidentiality rules • CTSI planning a recruitment service
Start-up • Protocol • Operations Manual • Forms • IRB approval • Hiring • Training • Database design • Database validation
Forms and Database Development • Define variables, create data dictionary • Determine method of data entry • Humans • Machine readable forms • Design database (CTSI Consultation) • Use prior forms - forms libraries • Pretest, validate
Adherence and Follow-up • Monitor rates • Obtain contact data at baseline • Pleasant, professional staff • Develop personal relationships • Encourage resumption of intervention and return to follow-up • Cards, small gifts, meetings, parties
Quality Control • Standard Operating Procedures • protocol • operations manual • statistical analysis plan • data and safety monitoring plan • Training and certification of staff • ethical conduct of research • measurements and other visit procedures • data entry • Performance review
Quality Control • Special procedures for quality control • study drug • laboratory procedures • data quality • missing, out of range, illogical • variation by site, investigator, staff member • Periodic checks of source data • Periodic reports (missing forms/data, queries, differences, drift)
Closeout • Final visit and post-trial plans • make final measurements • say goodbye and thank you • inform of test results • ?inform of treatment status • ?inform of trial results • ?make clinical recommendation
Summary • Trails are costly and complicated • get advice from experienced colleagues • get materials used in prior trials • use UCSF services • financial, legal, IRB/CHR • CTSI CRCs • CTSI Consultation Service • Design, ethics, statistics, database management
