About this trial

This study aims to characterize the safety, tolerability, pharmacokinetics, and preliminary efficacy of OL-CD19-GDT in relapsed/refractory autoimmune diseases.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Adults aged 18-65 years old

ECOG 0-2

Adequate organ function

Females of childbearing potential (FCBP) must have a negative pregnancy test at screening and must agree to use a highly effective contraceptive method starting from the time of lymphodepletion and for 2 years after dosing of the IMP

Disqualifiers

Active uncontrolled infection

Serologic evidence of chronic hepatitis B virus (HBV) infection and unable or unwilling to receive standard prophylactic antiviral therapy or with detectable HBV viral load

Serologic evidence of hepatitis C virus (HCV) infection without completion of curative treatment or with detectable HCV viral load

HIV antibody positive

Trial outcomes

Primary outcomes

1

Dose-limiting toxicity (DLT)

Adverse events will be assessed based on the CTCAE 5.0

Time frame
After OL-CD19-GDT administration up to 30 days (Day 1-Day 30)
2

Treatment emergent adverse event (TEAE) incidence and severity

Adverse events will be assessed based on the CTCAE 5.0

Time frame
From lymphodepletion through study completion, up to 2 years

Secondary outcomes

1

Overall Response Rate

The efficacy outcome variable, Overall Response Rate (ORR), is defined as the ratio between the number of subjects experiencing a response at weeks 12, 24 and 52 and the total number of enrolled subjects. A response to treatment will be considered as:\*SSc: Fulfillment of mCRISS criteria \*pSS: Achieving ESSDAI response

Time frame
Baseline through study completion, up to 2 years
2

Cmax of OL-CD19-GDT

The maximum concentration of the CAR-T cells will be measured to assess OL-CD19-GDT in vivo expansion and persistence.

Time frame
Baseline through study completion, up to 2 years
3

Tmax of OL-CD19-GDT

The time of the maximum concentration will be measured to assess OL-CD19-GDT in vivo expansion and persistence.

Time frame
Baseline through study completion, up to 2 years
4

AUC 0-28 days

Area under the curve will be measured to assess OL-CD19-GDT in vivo expansion and persistence.

Time frame
Baseline through study completion, up to 2 years
