About this trial

This is a prospective, single-arm, multicenter, phase II clinical trial to evaluate the efficacy and safety of Relmacabtagene Autoleucel in combination with the Sintilimab regimen for the treatment of relapsed/refractory B-cell lymphoma

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

The patient must be aware of and voluntarily sign the informed consent form (ICF).

Aged between 18 and 70 years, both male and female.

Pathologically diagnosed with DLBCL, FL, or MCL, with histological confirmation of CD19 positivity (immunohistochemistry or flow cytometry, with flow cytometry used for re-evaluation if immunohistochemistry is CD19-negative).

The patient must be willing to receive regorafenib and sintilimab treatment and be deemed suitable for this treatment by the investigator.

Disqualifiers

History of another malignancy that has not been in complete remission for at least 2 years, except for: non-melanoma skin cancer, completely resected stage I tumors with low recurrence potential, treated localized prostate cancer, biopsy-confirmed cervical carcinoma in situ, or squamous intraepithelial lesions detected by Pap smear and so on.

Active Hepatitis B: a) Positive for Hepatitis B surface antigen (HBsAg) and/or Hepatitis B core antibody (HBcAb) , with HBV-DNA below the lower limit of the reference value can be included.

Hepatitis C, HIV, or syphilis infection.

Uncontrolled systemic fungal, bacterial, viral, or other infections.

Trial design

Design model

Single group

Treatments tested in this trial

  • Autoleucel (Relmacabtagene Autoleucel)

    Drug

    Relmacabtagene Autoleucel will be reinfused 2 to 7 days after lymphodepletion (fludarabine + cyclophosphamide).

  • Sintilimab (PD-1 inhibitor)

    Drug

    Patients will receive intravenous Sintilimab (200 mg every 3 weeks) starting on Day 28 after reinfusion, continuing until disease progression or intolerable toxicity, with a maximum duration of 1 year.

Trial outcomes

Primary outcomes

1

The complete response rate (CRR) at 3 months

Time frame
Up to 3 months after Relmacabtagene Autoleucel infusion

Secondary outcomes

1

Disease-free survival (DFS)

To investigate the preliminary anti-tumor efficacy

Time frame
From the date of the first complete response to the date of the first documented progression or death from any cause, whichever came first,assessed up to 24 months
2

Progression-free survival (PFS)

To investigate the preliminary anti-tumor efficacy

Time frame
From the date of enrollment until the date of the first documented progression or death from any cause,whichever came first,assessed up to 24 months
3

Overall survival (OS)

To investigate the preliminary anti-tumor efficacy

Time frame
From the date of enrollment until the date of death from any cause, assessed up to 24 months
4

Number of participants with adverse events (AE) and severe adverse events (SAE) as assessed by CTCAE v5.0

To identify the incidence of AE and SAE

Time frame
Through study completion, an average of 2 years

Other outcomes

1

Investigating Immune Microenvironment, Proteomic, and Metabolomic Changes Associated with Treatment Efficacy Across Different Patient Group

To investigate the immune microenvironment changes, along with proteomic and metabolomic alterations, and correlate these variations with treatment efficacy across different patient groups.

Time frame
Through study completion, an average of 2 years
