If FDA grants an approval, it means the agency has determined that the benefits of the product outweigh the known risks for the intended use.
Why do most drugs fail?
The reasons for these failures appear to be unchanged: 75 to 80% are due to problems with efficacy and/or safety. And that, to me, is the second most important figure in the pharmaceutical industry, showing just how much we don’t know about what we’re doing.
Is it safe to participate in clinical trials?
Yes, all clinical trials have risks. But any medical test, treatment, or procedure has risks. The risk may be higher in a clinical trial because there are more unknowns. This is especially true of phase I and II clinical trials, where the treatment has been studied in fewer people.
How does a drug gets FDA approval?

As shown, the overall probability of success for all drugs and vaccines is 13.8%. (If oncology drugs are excluded, the figure is 20.9%.) But this number masks a wide variation by therapeutic area. Oncology drugs have a puny 3.4% success rate, while vaccines for infectious diseases have a 33.4% success rate.

Clearance: When a medical device is cleared, this means it has undergone a 510(k) submission, which FDA has reviewed and provided clearance.

One estimate holds it costs drug providers nearly $1 million per clinical trial participant.
Why do most clinical trials fail?
Failures can arise from a lack of efficacy, issues with safety, or a lack of funding to complete a trial, as well as other factors such as failing to maintain good manufacturing protocols, failing to follow FDA guidance, or problems with patient recruitment, enrollment, and retention.
Can clinical trials go wrong?
Clinical trials are the most important step in getting a drug approved by the FDA. Without them, no one would know if their medicines were safe. The vast majority of the time, these trials go well, and the medicine is approved for general use. But every once in a while, a clinical trial goes horribly wrong.
