Phase 1: These trials usually enroll 20 to 100 healthy volunteers or people with the condition being studied, and last several months. This phase measures safety by testing for any adverse side effects of the treatment, but not necessarily how effective the drug or device is.

How Long Does a Phase 1 Clinical Trial Take? The length of a phase 1 study is typically several months. How Long Does a Phase 2 Clinical Trial Take? The length of a phase 2 study can span several months to 2 years. This phase involves up to several hundred people, with researchers looking for the effectiveness and safety of the drug over a relatively short period of time. How Long Does a Phase 3 Clinical Trial Take? The length of study for phase 3 clinical trials is usually 1 to 4 years.

Phase 1, Phase 2, and Phase 3 Clinical Trials (combined) 6 to 7 years: FDA Review/Manufacturing: 0.5 to 2 years: Phase 4 Clinical Trial/Post-Market Surveillance/Report Adverse Events: 0.5 to 10 years (at least as long as the drug is on the market) 1

Clinical trials follow a particular timeline, from early, small-scale, phase 1 studies to late-stage, large-scale, phase 3 studies. 1 While there are many steps involved in the development of new drugs, clinical trials, which make up clinical research, are the part of drug development that involves people. Here we describe the key goals and provide information about the various clinical research phases.

Phase 1 clinical trials last from several months to a year, and usually have 10 to 80 participants. All information gathered from the phase 1 clinical trial helps researchers design the phase 2 study. Approximately 70% of drugs move on to phase 2 trials, according to the FDA.

Placebos (inactive treatments) are not used in phase I trials. Phase I trials usually include a small number of people (up to a few dozen). Phase I trials most often include people with different types of cancer. These studies are usually done in major cancer centers. Phase I trials carry the most potential risk.

There is no typical length of time it takes for a drug to be tested and approved. It might take 10 to 15 years or more to complete all 3 phases of clinical trials before the licensing stage. But this time span varies a lot. There are many factors that affect how long it takes for a drug to be licensed.

After the pre-clinical studies, there are four phases of trials in humans, which in practice often overlap. Phases 1 to 3 are done before a licence is granted and Phase 4 is done after authorisation to market the drug. The phases are different in terms of the number and types of subject studied, and the questions asked.

Stimulants including cocaine, meth, and ADHD medications are detectable for about 2 or 3 days. Benzodiazepines and MDMA generally flag a urine test for up to 4 days after last dose. Marijuana stays in the system a bit longer, with amounts being detectable for between 1 and 7 days after last use.

Most drugs of abuse stay in the body for at least a few days after the last use and are traceable with urine tests.

Follicle tests can detect drug use starting seven days back and up to 90 days back, depending on how long the hair specimen is. It can pick up on drugs only as recent as seven days because it takes three to seven days for drugs to become embedded in hair.
