Group A: Natalizumab Naïve
This group will consist of up to 10 people who are naïve to natalizumab (haven't received the drug before) and are just beginning therapy.
These participants will meet with the study staff at Week 0 (Baseline) prior to their natalizumab infusion.
They will then have a follow up appointment every 3 months for the first 12 months of their natalizumab infusions, for a total of 5 visits.
Natalizumab concentration and other biomarkers will be measured at each visit.
|
|
Group B: Intracycle Regular Dosing
This group will consist of at least 50 people who are on a regular infusing cycle of 28-31 days.
These participants will be consented at Week 0 (Baseline) and asked to come back each week during their regular cycle at Week 1, Week 2, and Week 3, for a total of 4 study visits.
Natalizumab concentration and other biomarkers will be measured during their participation in the study.
|
|
Group C: Intracycle Extended Dosing
This group will consist of up to 60 people who are on an extended infusing cycle of greater than 30 days.
These participants will be consented at Week 0 (Baseline) and asked to come back each week for a blood draw to measure Natalizumab concentration and other biomarkers during their extended cycle at Week 2, and Week 4, for a total of 3 study visits.
|
|
Group D: Transition Dosing
This group will consist of up to 10 people who are on a regular infusing cycle of 28-30 days who will be transitioning to an extended dosing cycle.
The decision to transition will be made by their treating neurologist.
These participants will be consented at Week 0 (Baseline) and will be followed for 8 cycles.
Natalizumab concentration will be measured at each cycle.
During certain cycles, other biomarkers will be measured.
