Following proof-of-concept in animal models, a clinical development program was launched that consisted of two observational studies, three open-label interventional studies and a long-term follow-up review analysis.
The pharmaceutical R&D productivity model proposed by Paul and coworkers1 indicates that approximately 11 small molecule compounds must enter clinical development to afford 1 NME launch every year.
The association between clinical development time and year of launch was maintained after excluding these drugs from the analysis (r=0.42, y=1.99×year 3912.46, p=0.006).
We sought to establish whether the time taken for the clinical development of new antiviral drugs launched in the UK had increased since the 1980s.
First-in-human studies are an extraordinary opportunity to integrate pharmacokinetic (PK), pharmacodynamic (PD), and toxicology information while launching the new molecule on a path for rational clinical development.
Dr. Harith Rajagopalan, the CEO and founder of Fractyl, said that the company is preparing to launch a multinational study by the end of 2014 and expects to start clinical development of Revita DMR in the U.S. during 2016.
Despite the risk, in 2013 a venture capital company called venBio bought the rights to TEV-48125 and launched a new company called Labrys Biologics and continued the antibody's clinical development.
It is therefore unsurprising that anti-obesity drug discovery programmes have been littered with false starts, failures in clinical development, and withdrawals due to adverse effects that were not fully appreciated at the time of launch.
As a result, sponsors need to consider, plan, and in some cases launch CV outcome trials during the FDA review of their New Drug Application based on limited data from the clinical development program, thereby adding complexity and substantial expense to the drug's development.
We sought to determine whether the overall time taken for the clinical development (clinical trial periods prior to filing and subsequent consideration by the regulator) of new drugs launched in the UK had changed over more than three decades, using data for antiviral drugs.
