What is a Phase 2 3 clinical trial?
A study that tests how well a new treatment works for a certain type of cancer or other disease and compares the new treatment with a standard treatment. Phase II/III clinical trials may also provide more information about the safety and side effects of the new treatment.
How many people are selected for Phase I trial?
During Phase 1 studies, researchers test a new drug in normal volunteers (healthy people). In most cases, 20 to 80 healthy volunteers or people with the disease/condition participate in Phase 1.
What is considered original research?
What is Original Research? Original research is considered a primary source. An article is considered original research if… it is the report of a study written by the researchers who actually did the study. the researchers describe their hypothesis or research question and the purpose of the study.
What is a Phase 3 study?
Phase III of a clinical trial usually involves up to 3,000 participants who have the condition that the new medication is meant to treat. Trials in this phase can last for several years. The purpose of phase III is to evaluate how the new medication works in comparison to existing medications for the same condition.
What are the three stages of research?
These include identifying the area of study, choosing the topic, formulating a research plan, collecting and then analysing the data and then finally writing up the study. These steps can be represented in three phases, namely the planning phase and the research phase and then finally the presentation phase.
What is a phase 1/2 clinical trial?
A study that tests the safety, side effects, and best dose of a new treatment. Phase I/II clinical trials also test how well a certain type of cancer or other disease responds to a new treatment.
How long do Phase 2 trials last?
about 2 years
What is the difference between Phase 2 and Phase 3 clinical trials?
Treatments that have been shown to work in phase II clinical trials must succeed in one more phase before they’re approved for general use. Phase III clinical trials compare the safety and effectiveness of the new treatment against the current standard treatment.
What is the standard format for a research paper?
Use these general guidelines to format the paper: Set the top, bottom, and side margins of your paper at 1 inch. Use double-spaced text throughout your paper. Use a standard font, such as Times New Roman or Arial, in a legible size (10- to 12-point).
What does a Phase 3 trial mean?
Phase III trials compare a new drug to the standard-of-care drug. These trials assess the side effects of each drug and which drug works better. Phase III trials enroll 100 or more patients. Often, these trials are randomized. This means that patients are put into a treatment group, called trial arms, by chance.
What are the 4 phases of FDA approval?
A step-by-step breakdown of the FDA’s drug approval process
- Preclinical phase. Before a drug company can test an experimental treatment on humans, it must prove the drug is safe and effective in animals.
- Phase one clinical trial.
- Phase two clinical trial.
- Phase three clinical trial.
- New drug application.
Why clinical trials take so long?
The clinical trial process is long – and it’s set up that way so that by the time drugs reach the public, they have been thoroughly evaluated. But the length of the process is one reason why it’s so important for volunteers to take part. Without enough volunteers, up to 80% of clinical trials are delayed.
What is a Phase 5 clinical trial?
A type of clinical study that follows Phase-4 (postmarketing) studies (in which additional information about the drug’s risks, benefits and optimal use that may be requested by regulatory authorities in conjunction with marketing approval).
How do you write the originality of a research paper?

- Extending, qualifying or elaborating on an existing piece of work.
