* Ruxolitinib treatment for \>=28 days with intolerance defined as new red blood cell transfusion requirement (at least 2 units/month for 2 months) while receiving a total daily ruxolitinib dose of \>=30 mg but unable to reduce dose further due to lack of efficacy.
* If receiving ruxolitinib at the time of screening, must currently be on a stable dose \>=10 mg twice daily of ruxolitinib for \>=4 weeks prior to the 1st dose of navitoclax.
