## TL;DR

Hadassah's home-made BCMA CAR-T, now called NXC-201, produced responses in three quarters of heavily pretreated myeloma patients in its first 20-patient study, with only mild cytokine release and no nerve toxicity, showing that a hospital can manufacture its own CAR-T cells.

## Summary

NCT04720313 is a phase 1 dose-escalation and safety study at Hadassah Medical Organization of HBI0101, a second-generation anti-BCMA CAR-T cell therapy developed and manufactured in an academic setting and infused fresh without cryopreservation, in relapsed or refractory BCMA-expressing multiple myeloma. Nexcella (now Immix Biopharma) is the collaborator and has taken the product forward as NXC-201.

The Haematologica 2023 report covers the first 20 heavily pretreated patients in three cohorts: 150 million CAR-T cells (6 patients), 450 million (7) and 800 million (7). Grade 1 or 2 cytokine release syndrome occurred in 18 patients (90 percent); there was no grade 3 or 4 cytokine release syndrome, no neurotoxicity of any grade and no dose-limiting toxicity in any cohort. The overall response rate was 75 percent, with a (stringent) complete response in 50 percent and a very good partial response in 25 percent. Responses were dose dependent: in the 800 million cohort the overall response rate was 85 percent, complete response 71 percent and minimal residual disease negativity 57 percent. Across cohorts the median overall survival was 308 days (range 25 to more than 466) and median progression-free survival 160 days at the June data cutoff, with six patients still progression free.

The registry lists the study as active, not recruiting, with an estimated 160 participants and a condition field reading "Dose Escalation and Safety" rather than a cancer, which is why the automated pass never attached it. The product's larger registered programme, NEXICART-2 (NCT06097832), is in AL amyloidosis and is a separate study.

## Fields

- Kind: Trial
- Status: active
- Last checked: 2026-09-24
- Also known as: HBI0101 phase 1; NXC-201 phase 1; MOH_2020-12-22_009584
- Registry id: NCT04720313
- Phase: 1
- Setting: Relapsed or refractory BCMA-expressing multiple myeloma: academic autologous anti-BCMA CAR-T HBI0101 (now NXC-201), given fresh without cryopreservation, in a dose escalation of 150, 450 and 800 million CAR-T cells
- Sponsor: Hadassah Medical Organization
- Enrolled: 20
- Result: Overall response rate 75%, (stringent) complete response 50% and very good partial response 25% in the first 20 patients; grade 1 to 2 cytokine release syndrome in 90%, no grade 3 to 4 cytokine release syndrome or neurotoxicity; median progression-free survival 160 days.
- Outcomes: Overall response rate: HBI0101 (NXC-201), all dose cohorts 75%; (Stringent) complete response rate: HBI0101 (NXC-201), all dose cohorts 50%; Median progression-free survival: HBI0101 (NXC-201), all dose cohorts 160 days; Grade 1 to 2 cytokine release syndrome: HBI0101 (NXC-201), all dose cohorts 90%
- Replication: Single-centre academic phase 1; the approved BCMA CAR-T products idecabtagene vicleucel and ciltacabtagene autoleucel reached registration through larger multicentre trials. NEXICART-2 (NCT06097832) tests the same cells in AL amyloidosis and has not reported.
