Lecture 3 Flashcards
Digitalis
Used to treat dropsy (congestive heart failure)
Ma huang
Heart stimulant and for nasal and chest congestion
Target identification
Identification of biological components that are potentially drugable
Target validation
Determines whether interfering with the target is likely to have an impact on cancer growth
Target to hit
Large numbers of chemical and biological agents are screened to identify molecules that hit the target
Hit to lead
Hits are further tested to determine which bind the target with my specificity
Lead optimization
Refining the properties of the lead molecules to enhance potency and reduce side effects
Preclinical testing
Test for effectiveness of optimize lead
Clinical trials
Determines whether it improves patient outcomes
Phase 1
3 to 18 months
Evaluate safety, tolerability, PK and effects in healthy volunteers
Phase 2
1-3 years.
Assesses effectiveness, side effects and other safety features and forms a dosing strategy and several HUNDRED patients
Phase 3
2-6 years
Establishes efficacy and adverse effects from long-term uses and THOUSANDS of patients
Phase 4
Continuous
Monitoring of effects contraindications and interactions reported by MD and Pharm.D.
IND
Investigational new drug application
Before phase 1
NDA
New drug application
After phase 3 before phase 4
