4. Pharmacokinetic measure of AUC for up to 24 hours (AUC0-24) [ Time Frame: up to 17 days ]
   The area under the concentration-time curve from time zero extrapolated to 24 hours post dose (AUC0-24) in plasma under fed or fasted condition
5. Pharmacokinetic measure of AUC for up to last measurable time point (AUC0-T) [ Time Frame: up to 17 days ]
   The area under the concentration-time curve from time zero extrapolated to last measurable timepoint (AUC0-T) of CHK-336 in plasma under fed or fasted condition
6. Pharmacokinetic measure of apparent terminal half-life (t1/2) [ Time Frame: up to 17 days ]
   Apparent terminal half-life (t1/2) of CHK-336 in plasma under fasted or fed condition
7. Pharmacokinetic measure of exposure accumulation ratios of CHK-336 [ Time Frame: up to 17 days ]
   The exposure accumulation defined as the ratio of last dose to single dose AUC0-24h with once a day dosing
8. Pharmacokinetic measure of exposure accumulation ratios (Cmax) for CHK-336 [ Time Frame: up to 17 days ]
   The exposure accumulation defined as the ratio of last dose to single dose Cmax with once a day dosing
9. Pharmacokinetic measure of the amount of CHK-336 excreted in urine [ Time Frame: Up to 24 hours ]
   Measure the amount of CHK-336 excreted in urine under fasted condition

Eligibility Criteria

• Ages Eligible for Study: 18 Years to 45 Years (Adult)

Criteria

Inclusion Criteria:

Healthy volunteers must meet all the following inclusion criteria to be randomized:

3. Contraception use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. All participants (male or female) who are of childbearing potential must agree to use highly effective contraception during the study. Female participants must continue to use highly effective contraception during the study for 30 days after the last dose of study drug. Female participants should not donate oocytes during this time. Male participants with female partners of childbearing potential must continue to use highly effective contraception during the study and for 90 days after the last dose of study drug. Male participants must agree not to donate sperm during this time. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the participant.
4. Women of childbearing potential (WOCBP) must have a negative serum pregnancy test at screening and Day -3 as well as a negative urine pregnancy test at Day 1 (predose). WOCBP must agree to undergo a pregnancy test during the study
