Estimating the Costs Associated with Novel Pharmaceutical development: Methods and Limitations.
Data sources for cost analysis of drug development R&D and clinical trials Cost estimates for pre-clinical and clinical development across the pharmaceutical industry differ based on several factors. One of these is the source of data used by each costing study to inform these estimates. Several studies use private data, which can include confidential surveys filled out by pharmaceutical firms/clinical trial units and random samples from private databases3,9,10,14,15,16. Other…
How much does developing a novel therapeutic cost? – Factors Affecting Drug Development Costs across the Pharma Industry: A mini-Report
Introduction Data evaluating the costs associated with developing novel therapeutics within the pharmaceutical industry can be used to identify trends over time and can inform more accurate budgeting for future research projects. However, the cost to develop a drug therapeutic is difficult to accurately evaluate, resulting in varying estimates ranging from hundreds of millions to billions of US dollars between studies. The high cost of drug development is not…
Bayesian approach for sample size estimation and re-adjustment in clinical trials
Accurate sample size calculation plays an important role in clinical research. Sample size in this context simply refers to the number of human patients, wheather healthy or diseased, taking part in the study. Clinical studies conducted using an insufficient sample size can lack the statistical power to adequately evaluate the treatment of interest, whereas a superfluous sample size can unnecessarily waste limited resources. Various methods can be…
