Discovery phase drug, Experimental, Pre-discovery phase drug
In DrugBank an experimental drug, also referred as a drug in discovery or pre-discovery phase, alludes to the drug development status in which the drug is being researched pre-clinically. A discover phase drug is being actively pursued but has not entered clinical trials. A pre-discovery phase drug is known to exhibit drug-like properties but has not been formally considered as a drug candidate. The experimental category in DrugBank captures both of these phases.
