 than one adequate and well -controlledPhase 3 clinical study may be required by the FDA for approval of an NDA. Progress reports detailing the results of clinical studies involving an IND must be submitted at least annually to the FDA and more frequently if serious adverse events occur. Phase 1, Phase 2 and Phase 3 clinical studies may not be completed successfully within any specified period, or at all. Furthermore, the FDA or the sponsor may suspend or terminate a clinical study at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical study at its institution if the clinical study is not being conducted in accordance with the IRB’s requirements or if the drug or biologic product has been associated with unexpected serious harm to patients. Concurrent with clinical studies, the company usually complete additional animal studies, develop additional information about chemistry and physical characteristics of the product candidate, and finalize a process for manufacturing the drug product in commercial quantities in accordance with cGMP requirements. The manufacturing must be capable of consistently producing quality batches of the product candidate and manufacturers must develop, among other things, methods for testing the identity, strength, quality and purity of the final drug product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life. In some cases, the FDA may approve an application for a product candidate but require the sponsor to conduct additional clinical studies to further assess the product candidate’s safety and effectiveness after approval. Such post -approvalstudies are typically referred to as Phase 4 clinical studies. These studies are used to gain additional experience from the treatment of a larger number of patients in the intended treatment group and to further document a clinical benefit in the case of drugs approved under accelerated approval regulations. 72 U.S. Marketing approval Assuming successful completion of the required clinical testing, the results of the preclinical and clinical studies, together with detailed information relating to the product’s pharmacology chemistry, manufacture, controls and proposed labeling, among other things, are submitted to the FDA as part of an NDA requesting approval to market the product for one or more indications. FDA approval of the NDA is required before marketing of the product may begin in the United States. Under federal law, the submission of most NDAs is subject to a substantial application user fee, and the sponsor of an approved NDA is also subject to annual product or program fees. These fees
