Adverse Event (AE): An unfavorable or unintended sign, symptom, reaction, or disease that is associated in time with the use of an investigational drug, whether or not the event is related to the investigational drug, or is expected.
Advertisement: In clinical trials, recruitment advertisements are any materials used for recruitment of study participants (for example, letters, bulletin board notices, and notices in newspapers, or on radio, television, or the internet).
Biomarker: A biomarker is a measurement of a variable related to a disease that may serve as an indicator or predictor of that disease. Biomarkers are parameters from which the presence or risk of a disease can be inferred, rather than being a measure of the disease itself.
Blinding: A procedure in which one or more parties to the clinical trial (i.e., the subject/patient, investigator, and/or sponsor medical personnel) are kept unaware of the treatment assignment(s) of the clinical trial participants. Used to remove potential for study bias.
Business Partner: Refers to major long-term business relationships that Lilly has entered with select entities for the in-licensing, out-licensing, co-development, co-marketing, or co-promotion of its products.
Clinical Trial / Study: Any investigation in humans intended to discover or verify the effects of an investigational drug or new use of an already marketed drug, and/or to identify any adverse reactions to the investigational drug with the object of determining safety and/or efficacy of the studied use. The terms “clinical trial” and “clinical study” are synonymous.
Clinical Trial Data: All collected information arising from patients entering a clinical trial.
Clinical Trial Material: The testing material used in a clinical trial, including the primary study drug, comparator drugs, and placebo as specified in the study protocol. Clinical trial material includes any investigational product, including medical devices, designed for human use.
Clinical Trial Material Package Lot Number: An identification number associated with clinical trial material that identifies a batch of clinical trial material and from which the production and distribution history can be determined.
Comparative Study: A study in which a participant is randomly assigned to one of two or more treatment groups for purposes of comparing the results of the separate treatment groups.
Comparator Drug: An investigational or marketed drug (i.e., active control) or placebo used as a reference in a clinical trial.
Completed Study: For this registry, a study is considered completed on the date of the last patient visit (of the patients enrolled in that study) by an investigator authorized to conduct the study by the sponsor and the IRB/ERB.
Confidential Information : Information not in the public domain that is private to the study participant (such as identity or personally identifiable health information), or that is proprietary to the sponsor (such as intellectual property and some study designs and endpoints).
Confirmatory Study : Studies designed to support the licensing of a drug that provides the following information: establish dose response relationship; demonstrate/confirm efficacy; establish a safety profile; and provide an adequate basis for assessing the benefit/risk relationship.
Co-operative group : A group of physicians and/or hospitals formed to treat a large number of patients in the same way so that new treatment can be evaluated quickly.
Core Registration Studies: Those primary safety and efficacy studies that the relevant government health agency uses to decide whether or not to approve the investigational drug or new use of a marketed drug. These studies are usually phase 3, always well controlled, randomized, of adequate size and, whenever possible, double blind. May also be called Pivotal or Confirmatory Trials.
Documentation: All records, in any form (including without limitation written, electronic, magnetic, and optical records, and scans, x-rays, and electrocardiograms) that describe or record the methods, conduct, and/or results of a trial, the factors affecting a trial, and the actions taken or omitted.
Dosing Regimen: The expected amount of study medication prescribed per time unit and duration of dosing (for example, 3 times/day for 7 days of therapy) as required in the study protocol.
Double-Blind Study: A clinical trial in which neither the investigator nor the study participant is aware of the treatment received.
Drug: Any recognized chemical compound that may be used on or administered to humans or animals as an aid in the diagnosis, treatment, or prevention of disease or other abnormal condition.
Enroll: The point at which a study participant is assigned to a study treatment in a clinical trial.
Enter: The act of obtaining informed consent for participation in a clinical study from participants deemed potentially eligible to participate in the clinical study.
Food and Drug Administration (FDA): A branch of the U.S. Department of Health and Human Services primarily responsible for regulating the approval and use of drugs, medical devices, cosmetics, and foods.
Good Clinical Practice (GCP): A standard for the design, conduct, performance, monitoring, auditing, recording, analysis, and reporting of clinical trials that provides assurance that the data and reported results are credible and accurate, and that the rights, integrity, and confidentiality of trial participants are respected and protected.
Hypothesis: A scientific idea about how something works, before the idea has been tested. Scientists do experiments to test a hypothesis and see if the hypothesis is correct.
Indication: The efficacy claims that are approved by the relevant government health agency for the medicine on the basis of the Core (Pivotal) Registration Studies. The indication is contained in the product label, also called prescribing information. The indications for a product may (and often do) differ by geography and country.
Informed Consent: A process by which a participant voluntarily confirms his or her willingness to participate in a particular clinical trial, after having been informed of all aspects of the trial relevant to the participant's decision to participate, including known and potential risks and benefits. Informed consent is documented by means of a written, signed and dated informed consent form.
Initiated Trial: See Study Start Date.
Institution (Medical): Any public or private entity or agency, or medical or dental facility, where clinical trials are conducted.
Institutional Review Board, or IRB: Also known in some countries as Ethics Review Board, or ERB. This is the scientific institution that is independent of the sponsor of the clinical trial that reviews and approves the study protocol on ethical treatment grounds and ensures that each participant enrolled in the trial has given their informed consent to participate. The IRB or ERB monitors the clinical trial from inception through completion.
Investigational New Drug Application (IND): After completing preclinical testing, a company files an IND with the U.S. Food and Drug Administration to begin to test the drug in humans. The IND becomes effective if FDA does not disapprove it within 30 days. The IND shows results of previous experiments; how, where and by whom the new studies will be conducted; the chemical structure of the investigational drug; how it is thought to work in the human body; any toxic effects found in the animal studies; and how the compound is manufactured. All clinical trials must be reviewed and approved by the Institutional Review Board (IRB) where the trials will be conducted (in Europe, the Ethics Review Board, or ERB).
Investigator: A health care professional responsible for the conduct of a clinical trial at a trial site and who coordinates with the study sponsor and the IRB. If a trial is conducted by a team of individuals at a trial site, the investigator is the responsible leader of the team and may be called the principal investigator.
Labeling: All labels and other written, printed or graphic matter on a medication or any of the medication’s containers or wrappers, or that accompany the medication, such as the prescribing information. The labeling of a medication includes a description of the uses for which the medication has been approved by the government for the geography where the drug will be marketed.
Last Patient Visit: The “Last Patient Visit” is considered the last study visit of the last patient remaining in the trial, anywhere in the world.
Marketed Drug: A drug product for which marketing authorization has been granted in at least one indication in a particular country by a government health agency. Once initial marketing approval is obtained, subsequent research may be ongoing for additional indications or formulations or as part of required safety follow up.
Methodology: The way in which information is found or something is done. The methodology includes the methods, procedures, and techniques used to collect and analyze information.
Multicenter Trial: A clinical trial conducted according to a single study protocol and identical methods at more than one investigative site, and therefore, carried out by more than one investigator.
New Drug Application (NDA): Following the completion of all three phases of clinical trial development, a company analyzes all of the data and files an NDA with the U.S. Food and Drug Administration if the data successfully demonstrate both safety and effectiveness. The NDA contains all the scientific information that the company has gathered on the investigational drug. NDAs typically run 100,000 pages or more and can take up to a year or longer to review by the FDA, on average. Once FDA approves an NDA, the new medicine becomes available for physicians to prescribe.
Observational / Non-Interventional Study: An observational study is defined as non-interventional research that involves the collection of scientifically valuable information for the purpose of answering an important research question. The term 'non-interventional' means that the healthcare provider's decisions regarding the proper treatment and care of the patient are made in the course of normal clinical practice.
Off-label Use: The prescribing of a medication by a physician or other healthcare provider for a use other than that which the medicine has been approved for marketing by a government health agency.
Open-label Study: A study in which the investigator and the study participant are aware of the drug therapy received during the study.
Patient Files: Hospital files, consultation records, or special patient files that are maintained and kept at the study site. In this context, also includes Phase 1 study participants, who are typically healthy volunteers without disease.
Pharmacokinetics: The actions of a drug in the human body over a period of time, including the absorption, distribution, metabolism, and excretion of the drug.
Phase (in relation to Drug Development): Drug development is divided into phases that are determined by the main objectives of the drug development process.
Pilot Study: A Proof-of-Concept study designed to explore new hypotheses. They are not intended to be used for registration.
Pivotal Study: Typically a Phase 3 study which presents the data required by a regulatory agency to decide whether or not to approve a drug. A pivotal study will generally be well-controlled, randomized, of adequate size, and whenever possible, double-blind.
Placebo: An inactive substance or “sugar pill” used in comparative studies. The placebo may be used in screening or washout periods or used as a comparator to determine the efficacy of a medication.
Primary and Secondary outcome measures: The measures collected in a clinical trial that are intended to answer the primary and secondary objectives of the trial.
Principles of Medical Research
Proof-of-Concept Study (POC): Any Phase 1b, or Phase 2 trial, regardless of sponsorship, that could generate, confirm, provide an adequate benefit-risk, or establish a dose response relationship that could be used as the basis for a decision to move forward with a registration strategy. This would include an initial indication, a supplemental indication, or a label change for a previously out-of- scope indication for a compound.
Protocol: A written action plan for a clinical trial. The plan states what will be done in the study and why. It outlines how many participants will take part in the study, what types of patients may take part, what tests they will receive and how often, what the treatment plan is, and the sponsor’s plan to analyze the data when the study is completed.
Recruitment: The stage of a clinical trial when human subjects or patients are being recruited to participate in the trial.
Recruitment Advertisement: In clinical trials, recruitment advertisements are any materials used for recruitment of study participants (e.g., letters, bulletin board notices, notices in newspapers, or on radio, television, or the Internet).
Scheduled Study End Date: For this registry, the scheduled study end date occurs when the study is completed. See Completed Study.
Screen: The act of determining if an individual meets minimum requirements to become part of a pool of potential candidates for participation in a clinical study.
Serious Adverse Event (SAE) or Serious Adverse Drug Reaction (Serious ADR): See: Adverse Event, Serious.
Side Effect: See Adverse Event.
Single-Blind Study: A study in which the treatment group assignment is not revealed to the study participant but is known by the investigator.
Sponsor: An individual, company, institution, or organization which takes responsibility for the initiation, management, and/or financing of a clinical trial.
Statistical Significance: A finding resulting from application of statistical procedures that a difference between a sample value and another value (either a constant or another statistic) is large enough to conclude that the two values being tested are different, that is, not due to chance or random error. The most commonly used confidence level for finding statistical significance is 0.05, meaning that there is a 5 percent or less probability that the difference observed was caused by “chance.” It is important not to confuse statistical significance with clinical importance. A difference may be statistically significant and yet be so small or due to such a commonplace cause as to be of no clinical importance. Some knowledge of the area of application is needed to judge the importance of a statistically significant finding. (Source: Olson, Statistics: Making Sense of Data ).
Status: Study participant recruiting status for a trial. For this registry, a trial can have one of the following statuses:
Study Coordinator/Study Nurse: The person at the investigative site who assists the investigator in the administrative coordination of the clinical trial.
Study Drug or Trial Drug: See Investigational Drug.
Trial Site: The physical location(s) where trial-related activities are actually conducted.
