A Study Comparing Anitocabtagene Autoleucel to Standard of Care Therapy in Participants With Relapsed/ Refractory Multiple Myeloma

Registration Number
NCT06413498
Lead Sponsor
Kite, A Gilead Company
Brief Summary

The goal of this study (iMMagine-3) is to compare the study drug, anitocabtagene autoleucel to standard of care therapy (SOCT) in participants with relapsed/refractory multiple myeloma who have received 1 to 3 prior lines of therapy, including an anti-CD38 monoclonal antibody and an immunomodulatory drug.

The primary objective of this study is to compare the efficacy of anitocabtagene autoleucel versus SOCT in participants with RRMM as measured by progression-free survival (PFS) per blinded independent review committee (IRC).

Detailed Description

After completing the treatment period, all participants who will receive anitocabtagene autoleucel, will be followed in the post-treatment follow-up period. Thereafter, participants will transition to a separate long-term follow-up study (KT-US-982-5968) to continue follow-up out to 15 years.

Scores from each subscale are transformed from 0 to 100. For the functional scales, high scores represent improvement. For the symptom scales, higher scores represent worsening.

Each scale is measured from 0 to 100 after a linear transformation. Higher scores for functioning scales and for the Global Health Status or Global HRQoL scales indicate a higher level of functioning and a better HRQoL respectively, whereas higher scores in symptom scales represent a high level of symptoms.

The EQ-5D-5L comprises 2 components: a questionnaire covering 5 dimensions and a tariff of values based upon direct valuations of health states using a visual analog scale (VAS). The total score for EQ-5D-5L index is presented on a range where higher scores indicate better outcome. A positive change from Baseline indicates improvement.
