Study Drug Administration:
Each cycle is 28 days.
If participant is found to be eligible to take part in this study, participant will receive
daratumumab by vein over about 4 hours on Days 1, 8, 15, and 22 of Cycles 1 and 2, Days 1 and
15 of Cycles 3-6, and then on Day 1 of Cycles 7 and beyond. Participant's first dose of
daratumumab will be given over about 7 hours.
In this study, the following will be done to lower the chance of a daratumumab infusion
related reaction:
- Participant will get medications, including steroids, acetaminophen, and/or
antihistamine before the infusion. If participant is considered high risk, participant
may also get medications, including inhaled steroids, after the infusion.
- The infusion may be slowed down or stopped if participant has a reaction.
- Participant may stay overnight in the hospital after the infusion so the study staff can
check participant's health.
Participant may ask the study staff for information about how these drugs are given and their
risks. Participant may also be asked to stay in the hospital overnight to watch participant
for side effects, if needed.
Length of Study:
Participant may receive daratumumab for up to 1 year. Participant will no longer be able to
take the study drug if the disease gets worse, if intolerable side effects occur, or if
participant is unable to follow study directions.
Study Visits:
Within 24 hours before participant's first dose of study drug, if participant can become
pregnant, blood (about 1 teaspoon) will be drawn for a pregnancy test.
Every 2 weeks during Cycles 1-6, blood (about 1 teaspoon) will be drawn for CMV testing.
On Day 1 of Cycles 1 and 2:
- Participant will have a physical exam.
- Blood (about 2 teaspoons) will be drawn for routine tests.
- Blood (about 2 teaspoons) will be drawn for pharmacokinetic (PK) testing before
participant's dose of study drug. Blood (about 1 teaspoon) for PK testing will also be
drawn 2 times over the 2 hours after the dose. During Cycle 2, blood will only be drawn
1 time after the dose. PK testing measures the amount of study drug in the body at
different time points.
- During Cycle 1, blood (about 1 teaspoon) will be drawn for immune system testing.
- During Cycle 2, participant will have a bone marrow aspirate/biopsy to check the status
of the disease.
On Days 2 and 4 of Cycle 1, blood (about 1 teaspoon) will be drawn for PK testing.
On Days 8, 15, 22 of Cycles 1 and 2, blood (about 2 teaspoons) will be drawn for routine
tests. On Day 8 of Cycle 1, blood (about 1 teaspoon) will be drawn before participant's dose
of study drug for PK testing.
Day 22 of Cycle 2, blood (about 1 teaspoon) will be drawn for PK testing before and after
participant's dose of study drug.
On Day 1 of Cycles 3-6:
- Participant will have a physical exam.
- Blood (about 2 teaspoons) will be drawn for routine tests.
- During Cycle 3, participant will have an EKG.
- During Cycle 3, blood (about 1 teaspoon each time) will be drawn for PK testing before
and after participant's dose of study drug.
- If participant can become pregnant, blood (about 1 teaspoon) will be drawn for a
pregnancy test.
On Day 1 of Cycles 3 and beyond, participant will have a bone marrow biopsy/aspirate to check
the status of the disease. If the disease appears to be responding to the study drug, the
study doctor will decide how often participant will have this procedure.
On Day 15 of Cycles 3-6, blood (about 2 teaspoons) will be drawn for routine tests.
On Day 1 of Cycles 7 and beyond:
- Participant will have a physical exam.
- Blood (about 2 teaspoons) will be drawn for routine tests and CMV testing.
- During Cycle 7 only, participant will have an EKG.
- During Cycles 7 and 12, blood (about 2 teaspoons) will be drawn for PK and immune system
testing.
- If participant can become pregnant, blood (about 1 teaspoon) will be drawn for a
pregnancy test.
While on study, if participant chooses to not have any of the PK blood draws, participation
in this study will be over.
End of Treatment:
About 28-35 days after the last dose of daratumumab:
- Participant will have a physical exam.
- Participant will have an EKG.
- Blood (about 2 teaspoons) will be drawn for routine tests.
- If the doctor thinks it is needed, participant may have a bone marrow biopsy/aspiration
to check the status of the disease.
Follow-Up Visits:
The study staff will call participant to ask how participant is doing 1 time each month for
the first year after participant's End-of-Treatment visit, then every 6 months during the
second year after the visit, and then 1 time every year after that. Each call should last
about 5 minutes.
At 4 and 8 weeks after participant's last dose of study drug, blood (about 2 teaspoons) will
be drawn for PK and immune system testing.
At 30 and 60 days after participant's last dose of study drug and then every 2-3 months after
that for 1 year:
- Participant will have a physical exam.
- If the disease appeared to be responding to the study drug, blood (about 2 teaspoons)
will be drawn for routine tests. Every 4-12 weeks, this sample may be used for CMV
testing. If the disease appears to get worse, participant will stop having these blood
draws.
- If the disease appeared to be responding to the study drug, participant will have a bone
marrow aspirate and/or biopsy.
- If the disease appeared to be responding to the study drug, participant will have an EKG
at participant's first follow-up visit.
After 1 year, participant may continue to have follow-up visits as part of participant's
routine care. This will be discussed with participant by the study doctor in more detail.
This is an investigational study. Daratumumab is FDA approved and commercially available for
treatment of multiple myeloma. It is considered investigational to use daratumumab to treat
ALL.
The study doctor can explain how the study drug is designed to work.
