Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Pharmacokinetic, Efficacy, Safety

Assess the ability of KAN-101 to attenuate gluten challenge (GC)-induced changes in duodenal histology as measured by changes in villus-height:crypt depth (Vh:Cd) ratio after a 2-week GC.

Secondary objectives 4

  1. Examine the impact of KAN-101 on biomarker response (interleukin-2 [IL-2]) in peripheral blood following GC.
  2. Determine the effects of KAN-101 on histologic features (intraepithelial lymphocytes [IELs] density) in duodenum biopsies following 2-week GC.
  3. Assess the safety and tolerability of KAN-101 in participants with CeD.
  4. Assess the pharmacokinetics (PK) of multiple doses of KAN-101 in participants with CeD.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 6

  1. Adults aged 18 to 70 years inclusive.
  2. Previously documented diagnosis of CeD based on positive serology (eg, tissue transglutaminase IgA antibody and/or DGP IgG) AND intestinal histology consistent with ≥ Marsh Type II or with evidence of villous atrophy.
  3. HLA-DQ2.5 genotype (HLA-DQA1*05 and HLA-DQB1*02) (homozygotes or heterozygotes).
  4. Negative or weak positive for transglutaminase IgA and negative or weak positive for DGP-IgA/IgG during screening.
  5. Have followed a gluten-free diet for ≥12 months immediately prior to study entry (self-reported).
  6. Screening intestinal biopsy demonstrating Vh:Cd ratio of 2.3 or higher.

Exclusion criteria 10

  1. Refractory CeD, defined as severe persistent or recurrent malabsorptive signs or symptoms with substantial villous atrophy (eg, documented Marsh score 3c in source data) despite strict adherence to a GFD for at least 12 months in absence of other disorders.
  2. Selective IgA deficiency.
  3. Positive for HLA-DQ8 genotype (DQA1*03, DQB1*0302) even if DQ2.5 is also present.
  4. Known wheat allergy.
  5. Diagnosis of type-I diabetes.
  6. History of dermatitis herpetiformis.
  7. Pregnant or breastfeeding.
  8. Known history of severe hypersensitivity reactions or anaphylaxis to gluten.
  9. Active gastrointestinal disease other than CeD (eg, inflammatory bowel disease, any forms of colitis except well-controlled microscopic colitis, uncontrolled IBS, peptic ulcer disease, eosinophilic esophagitis, and active GI infections).
  10. Previous treatment with tolerance-inducing therapies for CeD.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Changes from baseline in Vh:Cd ratio as assessed by esophagogastroduodenoscopy (EGD) with biopsy after 2-week GC (at Day 29).

Secondary endpoints 4

  1. IL-2 change from Day 15 (first day of GC) pre GC to Day 15 post GC.
  2. Changes from baseline in IEL density in duodenum biopsy after 2-week GC (at Day 29).
  3. •Incidence and severity of treatment emergent AEs as assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v6.0 (or higher). •Incidence and titer of KAN-101 anti-drug antibodies (ADA).
  4. Plasma concentration of KAN-101, and associated KAN-101 parameters: AUCinf, AUClast, Cmax, Tmax and t½.

Description
Three improperly randomized patients in the two clinical studies due to incorrect reporting of a genetic test result.
Sponsor actions
1. Requested vendor to open quality events and review results of the impacted test across the studies – vendor completed 24 Feb 2025 for QE 1 and 24 Mar 2025 for QE2 .

2. Notifications to affected sites and ethics committees to enable appropriate actions to be taken with patients (13 Feb 2025 for KAN-101-03) and the data safety monitoring board (DSMB, w/c 03 Mar 2025).

3. Vendor is revising internal processes (completion 17 Oct 2024) and implementing test-specific training of staff (completion 18 Apr 2025) before any manual reporting may be done.

4. Pfizer’s Regulatory Quality Assurance group will plan to audit Labcorp within the next 12 months.
