Head-to-head evidence
Ciltacabtagene autoleucel vs IM21 CAR-T cells
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

NCT03548207 · Phase 1/2 · completed
This was an open-label, single-group study with no randomized comparator and no blinding. Although the overall response rate among treated participants was high (e.g., 97.1% in the Phase 2 US population with 95% CI 89.8-99.6), the lack of a control arm means the results cannot be attributed to the drug with confidence. Uncontrolled single-arm evidence is inherently limited regardless of the response rate observed.

IM21 CAR-T cells
Developed by Beijing Immunochina Medical Science & Technology Co., Ltd.
NCT03711864 · Phase 1 · status unknown
This is a small, unblinded, single-arm safety study with no comparison group, and no results have been posted yet.
