Initial testing1
-
Obtain and evaluate baseline platelet counts and triglycerides prior to initiation of DUVYZAT
- Do not initiate DUVYZAT in patients with a platelet count <150 x 109/L
-
In patients with underlying cardiac disease or taking concomitant medications that cause QT prolongation, obtain ECGs:
- When initiating treatment with DUVYZAT
- During concomitant use if unavoidable
- When clinically indicated
- Avoid concomitant use with other drugs that prolong the QTc interval
- Withhold DUVYZAT if the QTc interval is >500 ms or the change from baseline is >60 ms
- Closely monitor when DUVYZAT is used in combination with an oral CYP3A4 sensitive substrate or a sensitive substrate of the OCT2 transporter, for which a small change in substrate plasma concentration may lead to serious toxicities

Required ongoing monitoring consists of 2 blood tests
After starting DUVYZAT, ongoing laboratory monitoring helps keep patients on track

CBC with differential
Monitor every 2 weeks for the first 2 months of treatment, at month 3, and then every 3 months thereafter
Triglycerides
Monitor at 1 month, 3 months, 6 months, and then every 6 months thereafter
In-home lab monitoring for your patients
Available for all patients enrolled in ITF ARC
ITF ARC's in-home lab monitoring program offers dedicated support that helps alleviate the logistical challenges patients may face with routine lab monitoring.
Dose can be modified for adverse reaction mitigation
Modifications may be needed for decreased platelet counts, diarrhea, increased triglycerides, or QTc prolongation.
CBC, complete blood count; ECG, electrocardiogram; QTc, heart rate–corrected QT interval.
