What are the types of clinical trials?

Clinical trials are generally divided into several types: Observational studies, in which researchers observe and measure health outcomes without intervening, e.g. studies for digital health applications (DiGA); intervention studies, in which researchers test a drug, surgical procedure, or other treatment; and diagnostic studies, which focus on better ways to detect specific disorders or diseases. Each type aims to answer specific questions about health and treatment.

What is the difference between a randomized and a non-randomized clinical trial?

In randomized trials, participants are randomly assigned to a treatment group (e.g. drug A and B). assigned, to ensure that the investigator's influence is not reflected in the study results. In some cases however on Randomization waived be. Dann is a non-randomized study and the allocation is assigned on the basis of a specific principle.

Is it safe to participate in a clinical trial?

Yes, the safety of the participants is a top priority. Clinical trials are carefully planned and monitored to minimize potential risks. Prior to participation, researchers must disclose all risks and potential benefits of a study, and participation is always on a voluntary basis.

What tests must a drug undergo before it is tested on humans?

Before a drug is tested on humans, it has a long-term development time behind it. At the very beginning, there is the active ingredient discovery. This involves a targeted search for an active ingredient that has a specific effect in human Body evokes. Once such an active ingredient has been identified, it must undergo many laboratory tests. If, after these trials, it is concluded that the drug is safe, it is finally tested on animals. Here checkswhether the distribution of active ingredients corresponds to the previous calculations. and whether the preparation has a toxic effect in the living organism. In addition must tested whether the new active ingredient achieves better results than drugs already approved on the market. preparations. Are these requirements fulfilleda Phase I study in humans can be applied for. For this all points are checked again by responsible authorities and ethics committees reviewed. Only then are drugs tested on humans in very small doses.

How am I insured during a study?

As a participant in a clinical trial, you are during the entire study period, i.e. from the first screening to the final examination, completely insured. Depending on the study, insurance is provided either by the client (also called the sponsor) or by the responsible Contract Research Organization. The insurance cover includes any damage incurred by the participant as a result of the study, and also covers the outward and return journey of the subject/patient.

Which phases must a drug or medical device pass through

SCREENSHOTS IN? Phase 1 In phase I trials, new drugs or new treatments are tested for the first time in a small group of healthy volunteers. This involves checking how the drug acts on the human organism (pharmacodynamics) and how it is absorbed, distributed, metabolized, degraded and excreted in the human body (pharmacokinetics). This determines the effective dosage at which the lowest possible side effects occur. The information collected on the safety and tolerability of a new drug is the basis for conducting a phase II trial. This can only be done if the side effects are not too severe. Phase II In phase II trials, new drugs are administered for the first time to patients suffering from the target disease. The goal of this phase is to determine a dose that will show the desired therapeutic effect while minimizing side effects. Phase III studies will not be approved until Phase II studies can demonstrate that side effects are acceptable. Phase III Phase III trials are conducted in a larger group of patients and are designed to confirm the safety, efficacy and safety of a drug. This phase runs under real-world conditions and is also designed to identify rare side effects, drug-drug interactions and optimal dosing. In this phase, the new drug is often compared in a comparative study against previous standard therapies or placebo. Thanks to intensive medical care, the risk for participating patients remains low. Phase IV
Phase IV trials are conducted after a new drug is approved. They are used to gather additional information on the efficacy and safety as well as long-term risks of a drug and are therefore performed in large patient groups. This means that even very rare side effects can be recorded.
