A Single-Center Review Of Therapies Used Prior To Alemtuzumab In Patients With Multiple Sclerosis
Objectives: The primary goal of the study will be to evaluate the prior DMT use and disease characteristics in patients who receive alemtuzumab for management of MS.
Methods: All adult patients >18 years of age who received alemtuzumab at Duke University Medical Center from January 1, 2015 to November 1, 2017 were retrospectively identified from the Lemtrada REMS facility database. Basic patient information including age, sex, year of diagnosis, date of first infusion, and details of prior DMTs were collected from the hospital electronic medical record.
Results: Data was available on 32 patients (ages ranging from 29-63, median age 42). The gender distribution of our patients was 74% female and 26% male. Patients received an average of 3.6 DMTs prior to alemtuzumab treatment. Avonex, Copaxone, Gilenya, Tysabri, and Tecfidera were the most frequently prescribed DMTs prior to treatment with alemtuzmab. Average time from diagnosis until treatment with alemtuzumab was 12 years, with a median time of 10 years.
Conclusions: Patients within our center have typically received 3-4 previous DMTs prior to alemtuzumab treatment. Within our cohort, treatment decisions were most often based on therapeutic failure of previous therapies as opposed to DMT intolerance.
