What is observational study?
In an observational study, investigators assess health outcomes in groups of participants according to a research plan or protocol. Participants may receive interventions (which can include medical products such as drugs or devices) or procedures as part of their routine medical care, but participants are not assigned to specific interventions by the investigator (as in a clinical trial). For example, investigators may observe a group of older adults to learn more about the effects of different lifestyles on cardiac health.

Why do we use clinical trials?
Often a clinical trial is used to learn if a new treatment is more effective and/or has less harmful side effects than the standard treatment. Other clinical trials test ways to find a disease early, sometimes before there are symptoms. Still others test ways to prevent a health problem.
Why participate in a clinical trial?
Others participate because there is no treatment for their health problem. By being part of a clinical trial, participants may find out about new treatments before they are widely available. Some studies are designed for, or include, people who are healthy but want to help find ways to prevent a disease, such as one that may be common in their family.
Why are older and diverse participants important in clinical trials?
It is important for clinical trials to have participants of different ages, sexes, races, and ethnicities.

Clinical trials of drugs are usually described ...
Why do we need older people in clinical trials?
Researchers need the participation of older people in their clinical trials so that scientists can learn more about how the new drugs, therapies, medical devices, surgical procedures, or tests will work for older people. Many older people have special health needs that are different from those of younger people. For example, as people age, their bodies may react differently to drugs. Older adults may need different dosages (or amounts) of a drug to have the right result. Also, some drugs may have different side effects in older people than younger people. Having seniors enrolled in drug trials helps researchers get the information they need to develop the right treatment for older people.

What is clinical measure?
a clinical measure to serve as the primary outcome, as well as a statistical measure to summarize the distribution of that clinical outcome across subjects.
What is phase 2 clinical trial?
Phase IIclinical trials seek further safety data and preliminary evidence in support of biological effect. A slightly larger sample of subjects are administered the treatment at a dose or doses that were preliminarily judged safe in the phase I studies. Safety data are collected in a systematic fashion, including specified monitoring of any potential side effects that were identified previously. Phase II studies also serve to screen for treatments that show some sign of biological effect, such as a biological marker that is a surrogate for the clinical outcome that is of interest. Products that fail to demonstrate a certain level of biological activity might be abandoned. Such a screening process is more efficient than other approaches in finding effective treatments from a large population of ideas.
What is the treatment discovery process?
The treatment discovery process is an iterative process of studying a disease, hypothesizing and developing treatments, evaluating those treatments, and, for successful treatments, further refining the indication to account for lack of efficacy or toxicities (or both) in particular subgroups of patients. As a rule, the scientific development of a particular treatment indication is often connected with that of other treatments, and thus it may be difficult to identify the exact process that led to the adoption of some treatment. Nevertheless, the following describes a general chronology of events.
What is intervention in medicine?
The InterventionAn intervention consists of a formulation of the drug(s)or device(s), a mode of administration, the dosing strategy, auxiliary treatments, and the duration of treatment. Some treatments are combinations of drugs, either in a common formulation or administered separately. A mode of administration can include topical, oral, subcutaneous, intramuscular, or intravenous. In some circumstances the mode of administration may even stipulate special training for the person administering the treatment. The dose may be specified as a common level to be used by all individuals or as a dose specific to patient body size or body surface area. The dosing strategy might include a gradual increase in dose as treatment is initiated, a tapering of dose as the patient is weaned from the therapy, a regimen for increasing or decreasing the dose in response to observed patient conditions at the time of dosing (e.g., serum glucose in insulin therapy) or observed patient response to therapy (e.g., increasing the dose if the effect is not optimal or decreasing the dose in the presence of treatment toxicity).
What is toxicology in medicine?

What is the term for the measurement of the effect of dose on the rate of absorption and excretion of drugs?
pharmacokinetics , measuring the effect of dose on rates of absorption and excretion of drugs from various body compartments;
What is the desired outcome of a treatment?
The Desired OutcomeThe intended outcome of a treatment is typicallycharacterized clinically, as outcomes that materially affect the clinical manifestations of the disease (e.g., lower risk of mortality, relief of symptoms, improvement in quality of life). In some settings, a strong risk factor thought to represent a surrogate outcome measure of subclinical disease or disease risk will be used (e.g., hypertension). The distinction between surrogate and clinical outcomes depends on the degree to which a patient’s sense of well-being is directly related to the outcome or the degree to which it is known that any modifications in the biomarker might possibly not be associated with an improvement in the clinical outcome (i.e., treating the symptom but not the disease). The precise definition of the outcome might explicitly include the time frame of measurement (e.g., postprandial serum glucose levels) and the method of measurement (e.g., decreasing serum glucose levels as reflected in Hemoglobin A1c), or the time frame might only be implicitly defined.
What are clinical trials?
Clinical trials are research studies in which people volunteer to help find answers to specific health questions. When carefully conducted, they are the safest and fastest way to find new treatments and ways to improve health.
Who should consider clinical trials and why?
Some people participate in clinical trials because none of the standard (approved) treatment options have worked, or they are unable to tolerate certain side effects. Clinical trials provide another option when standard therapy has failed. Others participate in trials because they want to contribute to the advancement of medical knowledge.
Where are clinical trials conducted?

What should I think about before joining a clinical trial?
Before joining a clinical trial, it is important to learn as much as possible. Discuss your questions and concerns with members of the health care team conducting the trial. Also, discuss the trial with your health care provider to determine whether or not the trial is a good option based on your current treatment. Be sure you understand:
What is a placebo and how is it related to clinical trials?
A placebo is a pill, liquid , or powder that has no treatment value. It is often called a sugar pill. In clinical trials, experimental drugs are often compared with placebos to evaluate the treatment’s effectiveness.
How do I find out what Phase a drug is in as part of the clinical trial?

What happens to drugs that don't make it out of clinical trials?
The drug developers go back to begin the development process using what they learned during with their preclinical research. Learn more about drug development.
How does treatment switching affect clinical trials?
Treatment switching can benefit clinical trial participants, but it may also affect how researchers interpret the trial’s results. In cancer clinical trials, researchers want to see if a new treatment stops cancer cells or delays their growth while increasing survival. But if people in the control group end up getting the new treatment, there really isn’t a control group anymore. If evaluating survival is the primary purpose of the study and the treatment switching is not planned, then the researchers may have a difficult time comparing the new treatment to the standard treatment.
What questions should I ask about treatment switching before I join a clinical trial?
If you’re considering being part of a clinical trial, ask if you’ll be allowed to switch treatments, so that you are clear on the rules of that clinical trial. You should also ask if extra information is being collected during the clinical trial so that the researchers can effectively account for treatment switching in the study results.
Is research continuing on treatment switching interpretations in clinical trials?
Researchers in Australia are developing a checklist to help specify the steps researchers must take when they present interpretations of treatment switching.
Why should you ask if extra information is being collected during the clinical trial?
You should also ask if extra information is being collected during the clinical trial so that the researchers can effectively account for treatment switching in the study results.
What is treatment switching?
Treatment switching, also called crossover, is where people in 1 clinical trial group start taking the treatment meant for another group. Usually treatment switching means that people in the control group start taking a new drug. There are several situations in which treatment switching may happen. It could be a planned part ...
What is crossover treatment?
These clinical trials separate participants into 2 or more groups. One group gets the new treatment and the other group, called the “control group,” receives a standard treatment. Treatment switching, also called crossover, is where people in 1 clinical trial group start taking the treatment meant for another group.
Why is treatment switching allowed?
In some cases, a data monitoring committee may require that treatment switching be allowed because one group is faring much better than the other and it is unethical to continue to keep the groups separate. Sometimes, treatment switching is unplanned, and patients take the experimental treatment if they can get it.
What is a cycle in cancer treatment?
A cycle means that you have a single cancer drug or a combination of drugs and then have a rest to allow your body to recover. You might have some chemotherapy injections over a day or two and then have some time with no treatment. The treatment and rest time make up one treatment cycle.
How long is a chemotherapy cycle?
Treatment cycles and courses of treatment. Cancer drugs such as chemotherapy are usually given in cycles over several months. A series of cycles is called a course of treatment.
