<<Would sure help an investor know when to jump in>>

I already jumped in quite a while ago with my two feet and keep "jumping" further in every chance I get.

Good luck to all.

Lee, I finally found some information (on FDA's web site) concerning approval rates of new drugs...this is drawn from a document entitled "From Test Tube to Patient: New Drug Development in the United States".

Phase 1

Number of Patients: 20-100
Length: Several months
Purpose: Mainly safety
Percent of Drugs Successfully Tested*: 70 percent

Phase 2

Number of Patients: Up to several hundred
Length: Several months to 2 years
Purpose: Some short-term safety but mainly effectiveness
Percent of Drugs Successfully Tested*: 33 percent

Phase 3

Number of Patients: Several hundred to several thousand
Length: 1-4 years
Purpose: Safety, dosage, effectiveness
Percent of Drugs Successfully Tested*: 25-30 percent

* For example, of 100 drugs for which investigational new drug applications are submitted to FDA, about 70 will successfully
complete phase 1 trials and go on to phase 2; about 33 of the original 100 will complete phase 2 and go to phase 3; and 25 to
30 of the original 100 will clear phase 3 (and, on average, about 20 of the original 100 will ultimately be approved for
marketing).

Based on this, there doesn't appear to be much fall off from Phase II to III. But it looks like only 2/3 of those clearing Phase III actually get approved. That seems surprisingly low. The FDA's CDER Annual Report for 1998 indicates some improvement in overall approvals, but they don't say exactly what the improvement is.
