简要总结
Background:
Chronic graft versus host disease (cGVHD) can affect people who had a hematopoietic stem cell transplant using donor cells. It is often fatal. It is usually treated with high doses of steroids. But that helps only about half the people in the long term. Researchers want to see if a drug called baricitinib can help people with cGVHD that has not responded to therapy. The drug inhibits the proteins involved in communication in the immune system. These proteins may play a role in cGVHD and other inflammatory diseases.
Objectives:
To test the safety and effectiveness of baricitinib in people with cGVHD that has not responded to therapy.
Eligibility:
Adults 18 and older with cGVHD that has not responded to therapy.
Design:
Participants will be screened with a medical history, physical exam, and blood and urine tests. They will have lung and heart tests and chest scans.
Baseline visit: Participants will have:
Medical history
Physical exam
Blood tests
Tests for infectious diseases
Skin, eye, and teeth evaluations
Rehabilitation and occupational medicine evaluations
Photos of any lesions
Gynecology evaluation (females)
The study will occur in 28-day cycles. Participants will take the study drug by mouth every day for 3 cycles. Some will take it for 3 or 6 more cycles.
Participants will have a few visits during each cycle. They will repeat some previous tests. They may also have scans and questionnaires.
Participants will have a visit when they stop taking the drug and another 3 months later. They will repeat a few study tests. They will have follow-up calls for 2 years.
详细描述
-
Background:
-
Chronic graft-versus-host disease (cGVHD) is the leading cause of non-relapse morbidity and mortality in persons after allogeneic hematopoietic stem cell transplantation (SCT).
-
Approximately 50% of patients with cGVHD have disease refractory to systemic corticosteroids; currently, there is no standard second-line therapy.
-
The Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway relays the signaling function of several inflammatory cytokines that have a role in GVHD (interferon (IFN)-gamma, Interleukin-2 (IL-2), Interleukin-6 (IL-6), Interleukin-12 (IL-12)).
-
Murine models have demonstrated activity of JAK inhibitors in graft-versus-host disease.
-
Baricitinib is a potent and selective inhibitor of Janus kinase 1 (JAK1) and Janus kinase 1 (JAK2) that has demonstrated anti-inflammatory effects and a good safety profile in patients with rheumatoid arthritis but has not been evaluated in GVHD.
-
Objectives:
-
To determine the safety and tolerability of baricitinib in patients with cGVHD that is refractory to steroids
-
To determine the efficacy of baricitinib in patients with cGVHD that is refractory to steroids
-
Eligibility:
-
Inclusion:
-
Age greater than or equal to 18 years
-
Moderate or severe cGVHD per NIH consensus criteria
-
Karnofsky performance status greater than or equal to 50%
-
cGVHD that did not respond to high-dose corticosteroids (prednisone at 1.0 mg/kg/day for at least 1 week or prednisone at 0.5 mg/kg/day or 1 mg/kg every other day for at least 4 weeks), or second-line therapy (any)
-
Receiving stable or tapering doses of systemic therapy in the preceding 4 weeks if taking systemic therapy for cGVHD

研究组 & 干预措施
Baricitinib
Single arm, intra-patient dose escalation. Arm 1 (starting dose) -Baricitinib starting at a dose of 2mg daily for 12 weeks. If the response at 12 weeks is a complete response (CR) and there has not been a dose-limiting toxicity (DLT), the dose will remain at 2mg daily for an additional 12 weeks. Arm 2 (dose escalation) - If the response is a partial response (PR) or stable disease (from cohort 1), the dose will be increased to 4mg daily for an additional 12 weeks. If there has been a DLT within the first 4 weeks will have a dose reduction back to 2mg daily.
Each participant is exposed to both dose levels (with the exception of participants who developed toxicity or progressive disease that caused them to discontinue study early before they were able to undergo the per-protocol dose escalation at 12 weeks).

结局指标
主要结局
Phase 1: Number of Participants With Dose-Limiting Toxicities (DLT)
时间窗: Starting at each dose level initiation, every 2 weeks up to the first 4 weeks of each dose
DLT is defined as any grade ≥3 non-hematologic or grade ≥4 hematologic adverse event, or hemoglobin \<6.5 g/dL, within 4 weeks of starting any dose level (1mg, 2mg, or 4 mg) except those that are clearly and incontrovertibly due to extraneous causes. Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). Grade 3 is severe. Grade 4 is life-threatening.
Phase 2: Number of Participants With Any Serious and/or Non-Serious Grades 3, 4, and/or 5 Adverse Events Due to Drug
时间窗: every 4 weeks through study completion (up to 48 weeks)
Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). Grade 3 is severe. Grade 4 is life-threatening. And Grade 5 is death related to adverse event.
Phase 2: Overall Response at 24 Weeks
时间窗: 24 weeks
Response was assessed by the National Institutes of Health (NIH) chronic graft-versus-host disease (cGVHD) response criteria. Complete Response (CR) is defined as resolution of all manifestations in each organ or site. Partial Response (PR) is defined as improvement at least 1 organ or site without progression in any other organ or site. Lack of Response including unchanged, mixed response, and disease progression. Mixed response is a CR or PR in at least 1 organ accompanied by progression in another organ. Unchanged is outcomes that do not meet the criteria for CR, PR, disease progression, or mixed response. Disease Progression is a change in the manifestations in each organ or site that does not meet the criteria for CR, PR, mixed response, unchanged or lack of response.
