Are There Different Types of Clinical Studies?'>
Clinical studies are done in four phases. Phase I is the first phase of testing. These studies use healthy volunteers, are short-term and establish the safety and tolerance of the medication. Phase II studies are short to medium length and use volunteers with the appropriate disease for the medication being studied in order to define medication dosages. Phase III studies are the last studies done before the medication is submitted to the FDA for approval. Phase III studies vary in length from several months to several years and use many volunteers with the appropriate disease for the medication being studied. These studies determine the medication’s safety and effectiveness with the selected dose in a large sample of volunteers and establish guidelines as to how the medication should be used. Phase III studies usually include a placebo (sugar pill) which means that some patients are not on active medication. Phase IV studies are conducted after the medication has been approved. Phase IV studies continue to monitor the safety of the medication in large groups of volunteers. AAIR Research conducts Phase II, III, and IV studies, with the majority being Phase III studies.
AAIR Research has and continues to perform clinical research studies in asthma, COPD, allergies, chronic hives, osteoarthritis, rheumatoid arthritis, sinusitis, and auto immune diseases including fibromyalgia, Raynaud's Phenomenon, lupus and Sjogren's Syndrome in adults and children. We are always looking for volunteers to participate in our clinical studies.
