- MAD(Multiple Ascending Dose) Study : confirmed excellent tolerability and pharmacokinetics profiles
B. PET(Positron Emission Tomography) Study
- Confirmation of both Serotonin and Dopamine trnasporters' inhibition in range of efficacy dose
C. DS(Drug Substance) and DP(Drug Product) Production
- 7Kg production of clinical drug substance
- Production of rapid action drug product for phase II
D. DS(Drug Substance) and DP(Drug Product) Stability Evaluation
- Confirmation of stability of DS and DP during 24 months
E. Non-clinical Toxicity Study
- 13 weeks general toxicity test : NOAEL 60mg/Kg/day(Rat), 6mg/Kg/day(Dog)
- Teratogenicity Segment II test : NOAEL 30mg/Kg/day(Rat), 45mg/Kg/day(Rabbit)
F. Clinical Pharmacological Study
- In vitro CYP450 inhibition study : confirmation of drug interaction using 8 kinds of human liver microsomal CYP450 isoenzyme up to 100uM
- Human metabolism study : Through the anaysis of metabolites, confirmation of multiple pathway's excretion
- Rat mass balance study : C14-labeled SKL10406 was excreted by 69~81% feces and 21~26% urine. Through the tissue distribution test, confirmation of no accumulation in any tissues
- MoA Study : completion of hippocampal neurogenesis test
- Human 5-HT/NE/DA transporter inhibition study : SKL10406 inhibits transportation about 3 neurotransmitters(5-HT/NE/DA) simultaneously
G. Food Effect Study
- Completion of protocol preparation for food effect study
H. Approval of Phase II
- Protocol for Phase II is being prepared to get approval from U.S. FDA
4. Future Plan
The clinical study results will be used as basic material for the design of late clinical trials. And it will be utilized as a marketing materials in out-licensing negotiations.
