Detailed Description

This project is a prospective, single-arm clinical study. It aims to apply Ivarmacitinib for the prevention of acute graft-versus-host disease (aGVHD) in patients with hematological malignancies undergoing HLA-mismatched transplantation. The primary objective is to observe the incidence of grade II-IV aGVHD after transplantation prevention. The secondary objectives include the incidence of primary graft failure, graft-versus-host disease-free and relapse-free survival (GRFS) at 12 months, the incidence of infection, the incidence of chronic graft-versus-host disease (cGvHD) within 100 days to 1 year, treatment-related mortality, the incidence and severity of cytokine release syndrome (CRS), and the safety assessment of the prevention regimen. This study is intended to provide a reference for the clinical application of Ivarmacitinib in transplantation. Therefore, this research is proposed to be conducted.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

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.

Ages Eligible for Study

  • KPS>60% or ECOG PS 0-2
  • Patients who have not received any other prophylactic immunosuppressive agents or aGVHD/cGVHD treatment are eligible
  • The female subjects of childbearing age are willing to use a medically approved highly effective contraceptive method (such as intrauterine device, contraceptive pill or condom) during the study period and within 180 days after the last administration of the study drug; for male subjects whose partners are of childbearing age, they agree to use an effective contraceptive method during the study period and within 180 days after the last administration of the study drug

Exclusion Criteria:

  • Pregnant women or women who are breastfeeding
  • Absolute Neutrophil Count (ANC) < 1.0 x 109/L or Platelet Count < 50 x 109/L
  • Uncontrolled active infections or active hepatitis B or hepatitis that requires antiviral treatment
  • Human Immunodeficiency Virus (HIV) positive
  • Uncontrolled concurrent diseases, including but not limited to persistent or active infections, autoimmune diseases, thrombosis, symptomatic congestive heart failure, unstable angina pectoris, unstable arrhythmias, or mental disorders/situations that would limit compliance with the study requirements
  • There are severe respiratory system diseases, severe renal function impairment, clinically significant or uncontrolled heart diseases, unresolved cholestasis and liver diseases (not attributable to aGvHD). Diseases that interfere with coagulation or platelet function and/or current drug treatments
  • Immunosuppressive doses of steroids. This does not exclude the use of steroids in subjects with adrenal cortical insufficiency
  • The diagnosis was clear: chronic lymphocytic leukemia, marginal zone lymphoma (MALT type), smoldering multiple myeloma, etc., all being low-grade malignant/cancer-preventing blood tumors
  • Patients who have been diagnosed with pre-transplantation digestive tract perforation and have a history of gastric or intestinal resection surgeries, etc., may have their drug absorption affected
  • It is known that there may be allergic reactions, hypersensitivity reactions or intolerance to the studied drug or its excipients
  • The researchers believe that there are any conditions that might harm the subjects or prevent them from fulfilling or meeting the requirements of the study

Experimental: Ivarmacitinib
During the dose exploration phase, the "3+3" method was used for Ivarmacitinib, with the dose incrementing from 2mg to 6mg. The medication was administered starting from -3 days and observation continued until 28 days after transplantation to determine the RP2D dose. Patients at the RP2D dose during the dose exploration phase were enrolled in the expansion study. Patients in the expansion study received RP2D Ivarmacitinib treatment daily for 3 days to 100 days.
Drug: Ivarmacitinib

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
incidence of grade II-IV aGVHD
Time Frame: up to 2 years
up to 2 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
the incidence of primary graft failure
Time Frame: up to 2 years
up to 2 years
the event-free survival (GRFS) without GVHD (12 months)
