What is the control group in a clinical trial?
In a clinical trial, the group that does not receive the new treatment being studied. This group is compared to the group that receives the new treatment, to see if the new treatment works.
Why do we need a control group in clinical trials?
Control groups have one major purpose: to allow discrimination of patient outcomes (for example, changes in symptoms, signs, or other morbidity) caused by the test treatment from outcomes caused by other factors, such as the natural progression of the disease, observer or patient expectations, or other treatment.
What is the purpose of clinical trials?
Clinical trials are research studies performed in people that are aimed at evaluating a medical, surgical, or behavioral intervention. They are the primary way that researchers find out if a new treatment, like a new drug or diet or medical device (for example, a pacemaker) is safe and effective in people.
Who has the control over clinical trial?
As set forth in the 2019-CTRules and the Hdbk-ClinTrial, the Central Drugs Standard Control Organization (CDSCO) is the regulatory authority responsible for clinical trial oversight, approval, and inspections in India.
Can a control group receive a different treatment?
The treatment group (also called the experimental group) receives the treatment whose effect the researcher is interested in. The control group receives either no treatment, a standard treatment whose effect is already known, or a placebo (a fake treatment).
Are control groups important?
Control groups are an important aspect of true experimental designs. The presence of control groups allows researchers to confirm that study results are due to the manipulation of independent variables (IVs) rather than extraneous variables.
What is the point of a control group?
A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.
What happens during a clinical trial?

What is a research team responsibility?
This includes but is not limited to; participant recruitment, obtaining informed consent, educating participants on the details of the research study, assessing participant eligibility, facilitating participant care and follow-up per protocol, creating source documentation, assisting in the assessment of toxicities/ …
Does a control group reduce bias?
Having more than one control group increases the power of a study and reduces the bias. Increase in power is achieved because of greater comparability as more information is available regarding potential differences in response between cases and controls.
Does a clinical trial need a control?
This would be the drug or device versus the condition of the patient. Control is a vital element of a well-designed experiment of the main variables. A good experiment, like a good clinical trial, often has blind controls or double-blind randomization to compare the end results.
What is a control group and are control groups still used in today’s medical research?
A control group is the group in a study that does not include the thing being tested and is used as a benchmark to measure the results of the other group and is one of the two groups in any valid experiment. The experimental group is the other one and is the group in which you are testing something.
What is a control group in a clinical trial?
Control Group: The group of participants that receives standard of care treatment. The control group may also be comprised of healthy volunteers. Eligibility Criteria: This refers to the factors or restrictions that determine who can participate in the clinical trial.
Should cancer clinical trials include placebo control groups?
In clinical trials that include placebos, quite often neither patients nor their doctors know who is receiving the placebo and how is being treated with the experimental drug. Many cancer clinical trials, as well as trials for other serious and life-threatening conditions, do not include placebo control groups.
What triggers the requirement to submit information for other clinical trials?
The voluntary submission of information for a clinical trial under 42 CFR 11.60 can trigger the requirement that information be submitted for other clinical trials (i.e., “triggered” trials) if certain conditions in the regulation are met.
