Incyte launches phase 3 trial of Itacitinib for acute graft-versus-host disease

Published 21 July 2017

Incyte reported that the first patient has been treated in a phase 3 trial dubbed GRAVITAS-301 for the first-line treatment of patients with acute graft-versus-host disease (GVHD).

The trial will evaluate the efficacy and safety of itacitinib, Incyte’s novel, potent, and selective JAK1 inhibitor, in combination with corticosteroids compared to placebo plus corticosteroids in patients with acute GVHD.

“Today, there are no approved treatment options for acute GVHD, a severe and life-threatening condition that can lead to tissue damage, organ failure, and death in certain transplant recipients,” said Steven Stein, M.D., Incyte’s Chief Medical Officer. “The initiation of the GRAVITAS-301 trial represents an important milestone for Incyte as we continue to progress our clinical development portfolio, and we look forward to further evaluating the potential of itacinitib to address the unmet needs of patients with this potentially devastating condition.”

GVHD is a condition that might occur after an allogeneic transplant (the transfer of genetically dissimilar stem cells or tissue), whereby the donated bone marrow or peripheral blood stem cells view the recipient’s body as foreign and attack the body.

GVHD can be acute or chronic, and is a significant cause of morbidity and mortality in transplant recipients. The skin, gastrointestinal (digestive) tract, and liver are the most commonly affected organs in patients with acute GVHD.

About GRAVITAS-301

GRAVITAS-301 (NCT03139604) is a randomized, double-blind, placebo-controlled pivotal Phase 3 study evaluating itacitinib or placebo in combination with corticosteroids as a first-line treatment for patients with acute GVHD. The study will enroll approximately 430 patients 18 years or older who have undergone one allogeneic transplant from any donor and any donor source for a hematologic malignancy or disorders.

The primary endpoint of the GRAVITAS-301 study is overall response rate (ORR) at Day 28, defined as the proportion of subjects demonstrating a complete response, very good partial response, or partial response. Key secondary endpoints include non-relapse mortality at Month 6, defined as the proportion of subjects who died due to causes other than malignancy relapse, duration of response, and ORR at Day 14, 56, and 100.
