To Assess Efficacy and Safety of Batoclimab in Adult Participants With Active CIDP

January 31, 2024 updated by: Immunovant Sciences GmbH

A Phase 2b, Multi-center, Randomized, Quadruple-blind, Placebo-controlled Study of Batoclimab Treatment in Adult Participants With Active Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

This is a multi-center, randomized, quadruple-blind, placebo-controlled study to evaluate the efficacy and safety of batoclimab in adult participants with active CIDP. The study includes an up to 4-week Screening Period, an up to 12-week Washout Period, a 12-week Randomized Treatment Period (Period 1), an up to 24-week Randomized Withdrawal Period (Period 2), an up to 52-week Long-term Extension (LTE) Period (optional), and Safety Follow-up 4 weeks after the last dose of study treatment. The total study duration will be up to approximately 109 weeks. Eligible participants will be assigned to one of four cohorts based upon their baseline CIDP treatment (Cohorts A and D - immunoglobulin [Ig] or plasma exchange [PLEX]; Cohort B - corticosteroids; Cohort C - naive or untreated in previous 3-24 months) and whether they meet diagnosis according to the European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) criteria (Cohorts A, B, and C) or clinical criteria only (Cohort D) at the time of screening.

Description

Inclusion criteria:

All Cohorts:

  1. Are >= 18 years at the Screening Visit.
  2. Have met clinical diagnostic criteria for typical CIDP, or one of the following CIDP variants: multifocal CIDP, focal CIDP, or motor CIDP in accordance with the EAN/PNS Guideline on Diagnosis and Treatment of CIDP. Clinical criteria for typical CIDP and variants are as follows (either criterion must be met):

    1. Typical CIDP: All the following:

      • Progressive or relapsing, symmetric, proximal, and distal muscle weakness of upper and lower limbs, and sensory involvement of at least two limbs (at any point in the disease course)
      • Developing over at least 8 weeks
      • Absent or reduced tendon reflexes in all limbs
    2. CIDP variants: One of the following, but otherwise as in typical CIDP (tendon reflexes may be normal in unaffected limbs):

      • Multifocal CIDP: documented sensory loss and muscle weakness in a multifocal pattern, usually asymmetric, upper limb predominant
      • Focal CIDP: sensory loss and muscle weakness in only one limb
      • Motor CIDP: motor symptoms and signs without sensory involvement

    Cohorts A and B:

  3. Have electrodiagnostic test results supporting the diagnosis of CIDP in accordance with the EAN/PNS Guideline on Diagnosis and Treatment of CIDP; for Cohorts A and B, either criterion must be met:

    1. Motor nerve conduction criteria strongly supportive of demyelination.
    2. Motor nerve conduction criteria weakly supportive of demyelination and 2 or more of the following additional diagnostic criteria:

      • Objective improvement to an empiric trial of therapy with immunoglobulin treatment, plasma exchange (PLEX), or corticosteroids.
      • Diagnostic imaging by ultrasound or magnetic resonance imaging (MRI) supporting the diagnosis of CIDP by demonstrating nerve enlargement.
      • Cerebrospinal fluid (CSF) demonstrating albuminocytologic dissociation (i.e., elevated CSF protein level [defined as > 70 milligrams per deciliter {mg/dL} or > 10 mg/dL greater than years of age for those aged 60 years and over] with normal CSF white blood cell [WBC] level).
      • Nerve biopsy demonstrating features supporting the diagnosis of CIDP, such as edema, demyelination, and/or onion bulb formation.

    Cohort C only:

  4. Have a diagnosis of CIDP in accordance with the EAN/PNS Guideline on Diagnosis and Treatment of CIDP based on clinical criteria and motor nerve conduction criteria strongly supportive of demyelination (i.e., motor nerve conduction criteria weakly supportive of demyelination is insufficient diagnostic evidence for admission to Cohort C).

    Cohort D only:

  5. Have met only clinical diagnostic criteria for typical CIDP, or one of the following CIDP variants: multifocal CIDP, focal CIDP, or motor CIDP in accordance with the EAN/PNS Guideline on Diagnosis and Treatment of CIDP. Either inclusion criterion 2(a) or 2(b) must be met.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Period 2, Cohort A: Proportion of participants who remain relapse-free at Week 36
Time Frame: Week 36
Relapse is defined as a worsening (increase) of >=1 point on adjusted inflammatory neuropathy cause and treatment (AdjINCAT) score at any time point during Period 2 relative to Period 2 Baseline which is sustained at a Follow-Up visit 1 week later. The INCAT disability scale is a widely used and validated efficacy assessment of neurologic dysfunction in CIDP. Upper and lower limb dysfunction are each separately assessed on a scale of 0-5 and results are summed together for a total composite score of 0-10. Higher scores represent greater disability. The Adj INCAT disability score is identical to INCAT disability score with exception that changes in upper limb function from 0 (normal) to 1 (minor symptoms) and vice versa are excluded since minor symptoms in the fingers, which are implied by an upper limb score of 1, are not considered clinically significant in all participants. The Adj INCAT disability score will be used for participant selection and measurement of clinical response.
Week 36

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Period 2, Cohort A: Time to first relapse relative to Period 2 Baseline
Time Frame: Baseline (Week 12) to Week 36
Baseline (Week 12) to Week 36
Period 2, Cohort A: Change from Period 2 Baseline in Adj INCAT score
Time Frame: Baseline (Week 12) and up to Week 36
Baseline (Week 12) and up to Week 36
Period 2, Cohort A: Change from Period 2 Baseline in Inflammatory Rasch-built Overall Disability Scale (I-RODS)
Time Frame: Baseline (Week 12) and up to Week 36
The I-RODS for immune-mediated peripheral neuropathies is a patient-based linearly weighted scale that captures activity and social participation limitations in patients with CIDP. The assessment consists of a 24-question instrument that addresses upper and lower limb tasks that range in difficulty from reading a book and eating to standing and running. Answers are scored on a scale of 0-2 (complete disability to no disability) and the raw scores are then transformed into a final score ranging from 0-100.
Baseline (Week 12) and up to Week 36
Period 2, Cohort A: Change from Period 2 Baseline in Mean grip strength
Time Frame: Baseline (Week 12) and up to Week 36
Mean Grip strength provides an objective, quantitative and immediate assessment of strength impairment. The Jamar dynamometer and the Martin vigorimeter are both commonly used to assess mean grip strength.
Baseline (Week 12) and up to Week 36
Period 2, Cohort A: Change from Period 2 Baseline in Medical Research Council (MRC) Sum Score
Time Frame: Baseline (Week 12) and up to Week 36
The MRC sum score is a standardized methodology for objectively assessing and reporting muscle function. Six muscle groups are assessed bilaterally, and each scored on a scale of 0 (no visible contraction) to 5 (normal) yielding a sum ranging from 0 (paralysis) to 60 (normal strength). Higher scores indicate normal muscle strength.
Baseline (Week 12) and up to Week 36
Period 2, Cohort A: Change from Period 2 Baseline in Overall Neuropathy Limitations Scale (ONLS)
Time Frame: Baseline (Week 12) and up to Week 36
The ONLS is a scale that focuses on upper and lower limb functions and was designed to assess the limitations of participants with immune-mediated peripheral neuropathies. This scale is completed by adding the total of the arm grade from zero point (less limitation) to 5 points (most limitation) and leg grade from zero point (less limitation) to 7 points (more limitation) yielding a total score of 0 (no disability) to 12 (maximum disability). Lower values in the ONLS indicate a better clinical condition.
