Study summary

The purpose of this trial is to evaluate the efficacy and safety of obecabtagene autoleucel (obe-cel) administered once following lymphodepletion in participants with severe, refractory systemic lupus erythematosus (SLE) and active lupus nephritis (LN).

Read the detailed description

This is a Phase 2 study to determine the efficacy and safety of obe-cel in participants with severe, refractory SLE with active LN.

The study comprises 3 periods:

  1. Screening Period: From Day -30 (+7) to Day of Enrollment
  2. Treatment Period: From Day -8 to Day 1 - Participants will be evaluated to confirm eligibility for lymphodepletion, and thereafter receive lymphodepletion.

    Obe-cel Administration: If the participant's eligibility for receiving obe-cel infusion is confirmed, the participant is to receive a single obe-cel infusion on Day 1.

  3. Post-treatment Period: From Day 1 to End of Study all participants will be followed up for efficacy and safety evaluation.

Inclusion criteria

  • Willing and able to give written for participation in the study or written informed consent signed by a legal guardian or representative
  • Ability and willingness to adhere to protocol's Schedule of Activities and other requirements
  • Participants must be 12 to 65 years of age inclusive at the time of signing the informed consent.
  • Female Participants: - a female participant is eligible to participate if she is not pregnant or breastfeeding
  • Diagnosis of SLE fulfilling the 2019 European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) Classification Criteria for Systemic Lupus Erythematosus.
  • Positive for at least 1 of the following autoantibodies: antinuclear antibodies (ANA), or anti-dsDNA or anti-Smith.
  • Severe, Active SLE defined as:

    • SLEDAI-2K score of ≥ 8 points AND
    • Severe active LN based on a renal : Class III, IV or V (V only in combination with class III or IV)
  • SLE defined as failure to

Exclusion criteria

Exclusion Criteria:

  • Prior treatment at any time with anti-CD19 therapy
  • More than 1 acute, severe lupus-related flare during screening that needs immediate treatment and/or makes the washout impossible
  • Significant, likely irreversible organ damage related to SLE (e.g., end-stage renal disease) that in the opinion of the Investigator renders CD19 CAR T cell therapy unlikely to benefit the participant
  • History of primary antiphospholipid antibody syndrome
  • Active or uncontrolled fungal, bacterial, or viral infection
  • History of malignant neoplasms unless disease free for at least 24 months
  • History of heart, lung, renal, liver transplant or hematopoietic stem cell transplant
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.
