Study summary

The purpose of this study is to evaluate the efficacy and safety of rapcabtagene autoleucel versus comparator in participants with severe active Granulomatosis with Polyangiitis (GPA) or Microscopic Polyangiitis (MPA)

Read the detailed description

This is a Phase 2, randomized, assessor-blinded active controlled study. This study comprises two cohorts:

  • A lead-in cohort enrolling participants to receive rapcabtagene autoleucel
  • A randomized cohort with participants receiving either rapcabtagene autoleucel or comparator.

After end of study (EOS), participants who received rapcabtagene autoleucel infusion will enter a long-term follow-up (LTFU) period lasting up to 15 years after rapcabtagene autoleucel infusion. This LTFU will be described in a separate study protocol.

Eligibility criteria

Key inclusion criteria:

  1. Men and women, aged ≥18 and ≤ 75 years with a diagnosis of GPA or MPA according to the American College of Rheumatology/ European League Against Rheumatism 2022 (ACR/EULAR 2022) classification criteria
  2. Positive test for ANCA-autoantibodies
  3. GPA and MPA participants with severe active disease

Key exclusion criteria:

  1. Any condition that could prevent a complete washout of medications or could otherwise make the participant ineligible for anti-CD19 CAR-T therapy and further participation in the study
  2. and/or to any product to be given to the participant as part of the study protocol
  3. Other systemic diseases requiring therapy
  4. Any medical conditions that are not related to GPA/MPA that would jeopardize the ability of the participant to tolerate CD19 CAR-T cell therapy
  5. Inadequate organ function
Terms in these criteria, in plain language(3)

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Event-free survival (EFS)

    Event-free survival (EFS) defined as the time from Randomization to the first occurrence of as per protocol defined events.

    Time frame: From randomization until the occurrence of an EFS event, up to approx. 4 years after randomization

Secondary outcomes

  1. Percentage of patients achieving complete remission

    Complete remission is defined by Birmingham Vasculitis Activity Score version 3 (BVASv3)

    Time frame: Up to Week 13

  2. Adjusted annual cumulative GC dose between Randomization and analysis cutoff date

    The adjusted annual cumulative glucocorticoid dose refers to the total amount of glucocorticoids administered to a patient over the course of a year, adjusted for any changes in dosage, and measured up to the defined week of treatment as per protocol.

    Time frame: From randomization until the occurrence of an EFS event, up to approx. 4 years after randomization

  3. ANCA seronegativity and sustaining ANCA seronegativity until the analysis cutoff date

    ANCA seronegativity means that the patient tests negative for ANCA antibodies.

    Time frame: From randomization until the occurrence of an EFS event, up to approx. 4 years after randomization

  4. Change from baseline in estimated glomerular filtration rate (eGFR) at Week 39

    Change from baseline in estimated glomerular filtration rate (eGFR) at Week 39.

    Time frame: Up to Week 39

  5. Change from baseline in symptoms of GPA/ MPA using the AAV-PRO at Week 39

    Change from baseline in symptoms of GPA/ MPA using the AAV-PRO at Week 39.

    Time frame: Up to Week 39

  6. Change from baseline in Patient- Reported Outcome Measurement Information System (PROMIS)- Fatigue 7a at Week 91.

    Change from baseline in PROMIS- Fatigue 7a at Week 91.

    Time frame: Up to Week 91
