Excessive regulatory oversight creates an elongated and expensive route to approval. By one estimate, an approved gene therapy drug costs nearly $5 billion (five times as high as the average cost of FDA approval).

What is a Phase 4 study?

Phase IV studies look at drugs that have already been approved by the FDA. The drugs are available for doctors to prescribe for patients, but phase IV studies might still be needed to answer important questions. These studies may involve thousands of people.

How long is FDA approval process?

The FDA aims to get a drug through the entire process in six months.

Who pays for clinical trials?

The sponsor of the study (such as the government, drug makers or technology companies) typically pays for all costs involved with a clinical research study. This includes supplying the new treatment, as well as any special testing, possible extra physician visits, and research costs involved in the clinical studies.

How long does clinical trials take?

Clinical trials alone take six to seven years on average to complete. Before a potential treatment reaches the clinical trial stage, scientists research ideas in what is called the discovery phase. This step can take from three to six years.

What is late stage drug development?

Late Stage Development means Development following completion of Phase II Studies up to and including filing of a Drug Approval Application for an Antibody Product in any jurisdiction and including any supplementary Development necessary or required by a Regulatory Authority (a) in order to obtain a Regulatory Approval …

What are the stages in drug development?

The clinical trials stage consist of three main phases and all new medicines have to go through these parts before they can be prescribed to patients. The clinical phase is there to establish the dose and best form of the drug, its safety, how it is absorbed by the body and furthermore whether the treatment works.

How long does it take to develop a drug?

On average, it takes at least ten years for a new medicine to complete the journey from initial discovery to the marketplace, with clinical trials alone taking six to seven years on average. The average cost to research and develop each successful drug is estimated to be $2.6 billion.
