Sitagliptin for the Treatment of Grade 3-4 and Refractory Acute Graft-versus-host Disease (GVHD)

January 29, 2021 updated by: moshe yeshurun, Rabin Medical Center

The prognosis of severe (grade 3-4) and steroid refractory acute graft-versus-host disease (GVHD) continues to be dismal. Sitagliptin given as GVHD-prophylaxis has recently been shown to reduce the incidence of acute GVHD to less than 10% with an excellent safety profile.

In this single center and single arm phase 2 study we aim to explore the safety and efficacy of sitagliptin in the treatment of severe and refractory acute GVHD.

Patient with new onset grade 3-4 acute GVHD will receive standard treatment consisting CNI and methylprednisolone 1-2 mg/kg/day or an equivalent dose of prednisone. Patients with refractory grade 2-4 acute GVHD will continue their current treatment; however methylprednisolone dose will be reduced to ≤ 1 mg/kg/day or an equivalent dose of prednisone.

Oral sitagliptin will be commenced at a dose of 100 mg BID. The dose will be increased by 100 mg every three days up to a maximal dose of 300 mg BID. In the case of significant drug related side effects or drug intolerance, the last tolerated dose will be resumed. Patients responding well to lower doses of sitagliptin, will not be given higher doses of the drug. Sitagliptin will be provided as long as deemed effective by the treating physician up to three months.

The primary end point will be the proportion of patients achieving complete remission(CR), very good partial response (VGPR) or partial response (PR) by day 28.

Detailed Description

The prognosis of severe (grade 3-4) and steroid refractory acute GVHD continues to be dismal. Sitagliptin given as GVHD-prophylaxis has recently been shown to reduce the incidence of acute GVHD to less than 10% with an excellent safety profile.

In this single center and single arm phase 2 study we aim to explore the safety and efficacy of sitagliptin in the treatment of severe and refractory acute GVHD.

Patient with new onset grade 3-4 acute GVHD will receive standard treatment consisting CNI and methylprednisolone 1-2 mg/kg/day or an equivalent dose of prednisone. Patients with refractory grade 2-4 acute GVHD will continue their current treatment; however methylprednisolone dose will be reduced to ≤ 1 mg/kg/day or an equivalent dose of prednisone.

Oral sitagliptin will be commenced at a dose of 100 mg BID. The dose will be increased by 100 mg every three days up to a maximal dose of 300 mg BID. In the case of significant drug related side effects or drug intolerance, the last tolerated dose will be resumed. Patients responding well to lower doses of sitagliptin, will not be given higher doses of the drug. Sitagliptin will be provided as long as deemed effective by the treating physician up to three months.

The primary end point will be the proportion of patients achieving CR, VGPR or PR by day 28. The secondary endpoints will be safety profile, proportion of patients achieving CR, VGPR or PR by day 56, 6-month duration of response (time from first response to GVHD progression or death), proportion of patients discontinuing immunosuppressive treatment by 3 and 6 months, proportion of patients developing chronic GVHD (limited and extensive) by 6 months, time to response, specific organ response, biomarker profile (ST2 and REG3a), Infection profile, OS at 6 months, GVHD free - disease free survival at 6 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
