CD4^LVFOXP3 in deelnemers met IPEX
Fase 1-studie van autologe CD4^LVFOXP3 bij deelnemers met immuundysregulatie Polyendocrinopathie Enteropathie X-linked (IPEX) syndroom
This first-in-human, Phase 1 clinical trial will test the feasibility of the manufacturing and the safety of the administration of CD4^LVFOXP3 in up to 30 evaluable human participants with IPEX and evaluate the impact of the CD4^LVFOXP3 infusion on the disease.
Studie Overzicht
Gedetailleerde beschrijving
Treatment with CD4^LVFOXP3 is expected to replace the defective Treg cells of the participants, and restore control of the immune system and therefore ameliorate symptoms of IPEX.
We expect to learn the following from this study:
- That CD4^LVFOXP3 can be consistently produced and be of expected quality to be used in humans,
- That CD4^LVFOXP3 are safe in children and young adults with IPEX, and determine its effects, both good and bad,
- That CD4^LVFOXP3 can improve overall health and allow reduction of medication/s.
This Phase 1 (feasibility and safety) trial will gather data about CD4^LVFOXP3 in vivo persistency and early signs of impact on symptoms of IPEX.

Experimenteel: Cohort A (≥12 years)
The first participant in Dose Level 1 will be administered 1.0 x 10^6 CD4^LVFOXP3 /kg (± 20%). If there is no toxicity observed in the first participant, the following participants in Dose Level 1 will be administered the same dose of 1.0 x 10^6 CD4^LVFOXP3 /kg (± 20%). If there is no toxicity observed in any participants in Dose Level 1, participants will be enrolled into Dose Level 2 and administered 3 x 10^6 CD4^LVFOXP3 /kg (± 20%). If there is no toxicity observed in any participants in Dose Level 2, participants will be enrolled into Dose Level 3 and administered 10 x 10^6 CD4^LVFOXP3 /kg (± 20%). If in any dose level 1 of 2 participants show toxicity, that dose level will be expanded to 6 participants. If there is no toxicity observed in any participants in Dose Level 3, participants will then be administered 10 x 10^6 CD4^LVFOXP3 /kg (± 20%) at two time points 21-42 days apart. |
Infusion of autologous CD4+ T cells that have undergone lentiviral-mediated gene transfer of: i) healthy human FOXP3 gene leading to persistent high FOXP3 expression and acquisition of Treg-like cell function; and ii) human CD271 surface marker gene that allows tracking and quantification of the CD4^LVFOXP3 in the blood.

Experimenteel: Cohort B (<12 years)
Participants in Cohort B will always follow treatment of participants in Cohort A for the same dose level. Cohort B will start at Dose Level 2 and be administered 3 x 10^6 CD4^LVFOXP3 /kg (± 20%). If there is no toxicity observed in any participants in Dose Level 2, participants will be enrolled into Dose Level 3 and administered 10 x 10^6 CD4^LVFOXP3 /kg (± 20%). If in any dose level 1 of 2 participants show toxicity, that dose level will be expanded to 6 participants. If there is no toxicity observed in any participants in Dose Level 3, participants will then be administered 10 x 10^6 CD4^LVFOXP3 /kg (± 20%) at two time points 21-42 days apart. |
