Only about 1 in 10 drug candidates that enter preclinical studies will ever reach market approval, a fact that underscores a critical aspect of what are the disadvantages of testing new drugs. This high failure rate reflects a complex and challenging process involving significant financial risks, potential harm to participants, and a long development timeline.

In clinical trials for major depression, the placebo effect accounts for a larger portion of the total benefit than the active drug itself, according to one meta-analysis. This startling fact highlights the powerful psychological and physiological phenomenon that explains exactly what does the placebo pill do and why it is so important for modern medicine.

According to the Biotechnology Innovation Organization (BIO), only about 31% of drugs successfully transition from a Phase 2 clinical trial to a Phase 3 study. This high attrition rate underscores the critical importance of successfully navigating **What is FDA Phase 2?**, the pivotal stage focused on confirming a drug's effectiveness and refining its optimal use in patients.

Basket trials have revolutionized modern oncology, allowing researchers to test a single drug's efficacy across multiple cancer types that share a specific genetic mutation. However, the term "what is the drug basket method?" also refers to an entirely separate, historical system for hospital pharmacy drug distribution, highlighting the importance of context when encountering this phrase.

According to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), over a thousand different adverse events are graded on a severity scale from 1 to 5. The mildest of these is grade 1 toxicity, representing asymptomatic or mild symptoms that do not require significant medical intervention.

In clinical trials, a Grade 4 toxicity represents a life-threatening adverse event where urgent intervention is required [1.2.1, 1.3.2]. Understanding this classification is crucial for evaluating drug safety. So, what is a grade 4 toxicity and how is it managed?
