Phase I trials involve a small number of healthy volunteers to evaluate the intervention's safety and dosage. Phase II expands the study to a larger patient population to further assess safety and efficacy. Phase III trials involve an even larger pool of patients and compare the intervention against standard treatment options. Phase IV trials are conducted post-approval to monitor the intervention's long-term safety and effectiveness once it is available to the general population.

Let's take a closer look at the preclinical research phase. This initial stage is crucial in determining whether a potential intervention is worth pursuing further. Researchers conduct laboratory tests to evaluate the intervention's mechanism of action and its potential effects on respiratory conditions. Animal studies are also conducted to assess the intervention's safety and efficacy before moving on to human trials. These preclinical studies provide valuable insights into the intervention's potential benefits and any potential risks or side effects.

Once the preclinical research phase is completed and the intervention shows promise, it progresses to Phase I trials. During this phase, a small group of healthy volunteers is carefully selected to participate. The primary goal of Phase I trials is to evaluate the intervention's safety and determine the appropriate dosage. Participants are closely monitored, and their vital signs, blood samples, and any potential side effects are carefully recorded. This phase helps researchers understand how the intervention interacts with the human body and provides valuable information for further development.
