Extended Data Table 4 Results summary for main exploratory efficacy end points – by day +365

From: Vedolizumab for the prevention of intestinal acute GVHD after allogeneic hematopoietic stem cell transplantation: a randomized phase 3 trial

  1. Results of the main exploratory study end points analyzed by day+365 after allo-HSCT. Analyses included all randomized patients who received ≥1 dose of study treatment and allo-HSCT. All statistical tests were two-sided.
  2. * Number (%) of patients with an observed event/relapse/death (as applicable), whichever occurred first, from first study treatment dose (day −1) through day +365.
  3. † Obtained via log-rank test unless otherwise stated.
  4. ‡ Obtained via Cox proportional hazards model with treatment group, stratified by randomization stratification factors: HLA match (7/8, 8/8), conditioning regimen (Myeloablative, Reduced Intensity), ATG (With, Without) unless otherwise stated.
  5. § Competing risk analysis with relapse and death as competing risks. P-value obtained by Gray’s test.
  6. ¶ GVHD and relapse-free survival was the time from the date of first study treatment dose (day-1) to GVHD event/death/relapse, where an event is defined as death or aGVHD grade 3–4 by modified Glucksberg criteria9 (Supplementary Table 2) or chronic GVHD requiring system immunosuppression or relapse.
  7. Competing risk analysis with death as competing risk. P-value obtained by Gray’s test.
  8. ** Hazard ratio obtained via Cox proportional hazards model with treatment group adjusting for complete remission status and randomization stratification factors: HLA match or mismatch (8/8 or 7/8), Conditioning Regimen (Myeloablative, Reduced Intensity), and ATG (With, Without).
  9. ††P-value for comparison between vedolizumab and placebo was obtained using Wilcoxon rank-sum test.
