## Arms

- **Anti-CD19/BCMA CAR gene vector injection** (EXPERIMENTAL) — Intravenous infusion of Anti-CD19/BCMA CAR gene vector injection

## Interventions

- **Anti-CD19/BCMA CAR gene vector injection will be injected intravenously on a one-time basis** (DRUG) — A single intravenous infusion of anti-CD19/BCMA CAR gene vector injection(dose-escalating infusion of 1.0-4.0 x10\^6 TU/kg）

## Primary Outcomes

- **Adverse events** _(time frame: up to 1 years)_ — Total number, incidence and severity of adverse events (AEs) in patients of LCAR1901 infusion. The AEs will be assessed according to the 2019 Consensus on Cytokine Release Syndrome and Immune-cell-associated Neurotoxicity published by the American Society of Transplantation and Cell Therapy (ASTCT), the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5.0 and EBMT 2019 consensus

## Secondary Outcomes

- **The persistence of CAR gene vector injection** _(time frame: up to 1 years])_
- **Disease activity was assessed by DAS28** _(time frame: up to 1 years)_
- **Modified Rodnan Skin Score assesses disease activity in patients** _(time frame: up to 1 years)_
- **SLEDAI assesses disease activity in patients** _(time frame: up to 1 years)_
- **BILAG-2004 assesses disease activity in patients** _(time frame: up to 1 years)_
- **Change from baseline in Physician's Global Assessment of Arthritis (PGA) (VAS)** _(time frame: up to 1 years)_
- **Change from baseline in ESR** _(time frame: up to 1 years)_
- **Clinical response for Sjögren's Syndrome** _(time frame: up to 1 years)_
- **HAQ health assessment** _(time frame: up to 1 years)_
