What do they mean by "Novel Drugs" that companies make?

Answers:
It means the drug is new or different from other drugs. many drugs are in classes (barbiturates, benzodiazapines, opiates, etc), and one would see a novel drug as being a completely new drug--lacking structural similarities with any yet-characterized class of drugs, and likely exerting its mechanism of action in a different way than known drugs.
