---|---|
Experimental: ABBV-181 plus Venetoclax
Venetoclax will be taken once daily beginning 7 days prior to cycle 1 and continuing daily for a 28 day cycle and ABBV-181 will be administered every 4 weeks.
|
Drug: Venetoclax
Tablet taken orally Drug: ABBV-181 Intravenous infusion
Other Name: Budigalimab |
Experimental: ABBV-181
ABBV-181 will be administered at escalating dose levels in 28-day dosing cycles (2 doses per cycle). Based on available safety, pharmacokinetic, and pharmacodynamic data from the dose-escalation part of the study, participants will be enrolled in dose-expansion cohorts to further evaluate ABBV-181 at a dose level which is at or below the Maximum tolerated dose (MTD). In the Monotherapy Expansion portion of the study, ABBV-181 will be administered in 28-day dosing cycles at either 1 dose per cycle or 2 doses per cycle. Based on available safety, PK and PD data from the single agent dose-escalation part of the study, a dose for ABBV-181 will be selected to evaluate in combination with Rovalpituzumab Tesirine or venetoclax.
