Current Nonclinical Testing Paradigm for Drug Development: A Regulatory Perspective To support clinical trials and marketing authorization for pharmaceuticals, certain nonclinical studies on the pharmacology, pharmacokinetics/ADME, and toxicology are recommended based on ICH guidances. The types of nonclinical studies are determined by many factors including the type of drug, clinical indication/population, scope of clinical investigations, and existing nonclinical or clinical experience. In recent years, new approaches such as alternative methods and non-animal methods are being introduced to replaces the use of animals, reduce the number of required laboratory animals, or refine a test procedure in accordance with 3R (reduce/refine/replace) principles. In this presentation, I will discuss the current regulatory considerations and key nonclinical studies to support investigational and marketing application submissions based on publicly available information and guidelines.

Clinical Development Strategy: The Good and The Ugly The clinical development of new drugs is a complex and highly regulated process that presents both significant valuation opportunities and challenges. It is essential for bringing innovative therapies to market, improving patient outcomes, and addressing unmet medical needs. However, the journey from translation of non-clinical information to regulatory approval is fraught with scientific, financial, and logistical hurdles. Challenges of clinical development attribute to high costs with high failure of new drug development. Despite these challenges, comprehensive development strategies and operations reflecting continued innovation, strategic planning, and regulatory adaptation can help expedite the clinical development of new, life-saving drugs. In this presentation, cases with a best clinical development strategy and master plan will be highlighted how valuation can be enhanced through better clinical development strategy provided the timely execution, and those may lead to a game changer.

Regulatory Strategies in Successful Drug Development and Approval New drug development is a high-risk, expensive and long-term endeavor: it can take 10 to 15 years and average cost to develop a new drug may exceed $2.5 billion. Its success rate is relatively low, but if drug development succeeds, it can yield high returns.
Successful drug development requires thorough early strategic planning. It needs to begin with the goal in mind throughout the entire drug development process, and both drug development and regulatory strategies should be planned and executed accordingly. It is also very important for successful drug development to have good understanding of how a regulatory agency works and to efficiently interact with them. For drug companies pursuing novel drug developments, it is critical to understand regulatory agency’s review process and review tools, to utilize the programs which facilitate new drug developments, and to seek input from them for guidance.
In this presentation, the following topics will be discussed:

• FDA’s expedited program
• FDA’s review process and PDUFA VII
• Meetings with FDA including new meetings created under PDUFA VII

The emphasis of the presentation will be on the keys for efficient interactions with the FDA.
