- Part A: Concentration-time curve (AUC) for single and multiple dose of ARV-110 [ Time Frame: 28 Days ]PK parameters will be assessed when applicable after a single dose and after multiple once and twice daily doses. Assessment of pharmacokinetic parameter area under the concentration-time curve (AUC).
- Part A: Maximum concentration (Cmax) for single and multiple dose of ARV-110 [ Time Frame: 28 Days ]PK parameters will be assessed when applicable after a single dose and after multiple once and twice daily doses. Assessment of pharmacokinetic parameter maximum concentration (Cmax).
- Part A: Minimum concentration (Cmin) for single and multiple dose of ARV-110 [ Time Frame: 28 Days ]PK parameters will be assessed when applicable after a single dose and after multiple once and twice daily doses. Assessment of pharmacokinetic parameter minimum concentration (Cmin).
- Part A: Time to maximum concentration (Tmax) for single and multiple dose of ARV-110 [ Time Frame: 28 Days ]PK parameters will be assessed when applicable after a single dose and after multiple once and twice daily doses. Assessment of pharmacokinetic parameter time to maximum concentration (Tmax)
- Part B: Concentration-time curve (AUC) for single and multiple dose of ARV-110 [ Time Frame: 28 Days ]PK parameters will be assessed when applicable after a single dose and after multiple once and twice daily doses. Assessment of pharmacokinetic parameter area under the concentration-time curve (AUC).
- Part B: Maximum concentration (Cmax) for single and multiple dose of ARV-110 [ Time Frame: 28 Days ]PK parameters will be assessed when applicable after a single dose and after multiple once and twice daily doses. Assessment of pharmacokinetic parameter maximum concentration (Cmax).
- Part B: Minimum concentration (Cmin) for single and multiple dose of ARV-110 [ Time Frame: 28 Days ]PK parameters will be assessed when applicable after a single dose and after multiple once and twice daily doses. Assessment of pharmacokinetic parameter minimum concentration (Cmin).
- Part B: Time to maximum concentration (Tmax) for single and multiple dose of ARV-110 [ Time Frame: 28 Days ]PK parameters will be assessed when applicable after a single dose and after multiple once and twice daily doses. Assessment of pharmacokinetic parameter time to maximum concentration (Tmax)
- Part B: Duration of response [ Time Frame: 12 Weeks ]From the date of first confirmed best overall response of CR or PR to the date of first progression per RECIST 1.1 or PCWG3, or death due to any cause without evidence of radiographic progression, whichever occurs first.
