Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Participants must be males or females age 18 years or older.
- Participants with Stage 1 to 4 (per the Modified Keystone Grading Schema) acute GVHD of the lower GI tract, without signs of chronic GVHD, at the time of diagnosis, which developed in the first 180 days following allogeneic hematopoietic cell transplantation (HCT) using bone marrow, peripheral blood, or cord blood; or after preplanned donor lymphocyte infusion.

- Participants with relapsed/persistent malignancy requiring rapid immune suppression withdrawal.
- Participants who received an unplanned (not part of the original transplant therapy plan) donor lymphocyte infusion.
- Participants who received previous systemic treatment for acute GVHD, except for a maximum of 3 days (72 hours) of 2 mg/kg corticosteroid therapy.
- Participants with unresolved veno-occlusive disease of the liver.
- Participants with creatinine clearance <40 milliliters (mL)/minute at Screening, as calculated by the Cockcroft-Gault formula.
- Participants known to be infected with human immunodeficiency virus (HIV), hepatitis B, or hepatitis C.
- Participants known to have an uncontrolled thyroid disorder.
- Participants who are pregnant, breast feeding, or sexually active and unwilling to use effective birth control for the duration of the study.
- Participants who participated in any other investigational drug trial or had exposure to any other investigational agent, device, or procedure <4 weeks prior to Screening and throughout the entire trial, with the exception of investigational drugs administered prophylactically for cytomegalovirus (CMV) post allogeneic HCT.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: ALXN1007 10 mg/kg once weekly
Cohort 1, the first dosing cohort, received 10 mg/kg ALXN1007 IV once weekly for 8 weeks.
|
ALXN1007 is a recombinant humanized monoclonal antibody that binds to complement component C5a and its metabolite C5a desArg.
|
Experimental: ALXN1007 20 mg/kg once weekly
Cohort 2 received 20 mg/kg ALXN1007 IV once weekly for 8 weeks.
For the first 2 participants enrolled, the first ALXN1007 dose was not to be administered on the same day and a safety and tolerability review was to take place after the second (and prior to the third) ALXN1007 dose for each participant.
If the ALXN1007 dose was determined to be sufficiently tolerated by the participant, dosing was to continue for that participant.
For any other participants enrolled in the dosing cohort, participants were not to proceed to the third ALXN1007 dose prior to the completion of the safety and tolerability review (of the first 2 doses) for the first 2 participants.

Experimental: ALXN1007 20 mg/kg twice weekly
Cohort 3 received 20 mg/kg ALXN1007 IV twice weekly for 8 weeks.
For the first 2 participants enrolled, the first ALXN1007 dose was not to be administered on the same day and a safety and tolerability review was to take place after the second (and prior to the third) ALXN1007 dose for each participant.
If the ALXN1007 dose was determined to be sufficiently tolerated by the participant, dosing was to continue for that participant.
For any other participants enrolled in the dosing cohort, participants were not to proceed to the third ALXN1007 dose prior to the completion of the safety and tolerability review (of the first 2 doses) for the first 2 participants.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Overall Acute Graft-Versus-Host Disease (GVHD) Response Rate At Day 28
Time Frame: Day 28
|
The number of participants with overall acute GVHD response was determined at Day 28.
Acute Overall GVHD is defined as improvement from diagnosis in any organ by at least 1 stage, without progression in any other organ, and with no additional therapy being administered.
Acute GVHD staging included skin, liver, and GI assessments, which were to be performed using the Modified Keystone Grading Schema.
Deaths were considered nonresponders; otherwise last postbaseline values were carried forward for imputation of missing responses.
Modified Keystone Grading Schema: Skin - Stages 0 = No Rash, 1 = Rash <25% body surface area (BSA), 2 = 25% to 50% BSA, 3 = >50% BSA, 4 = bullae, desquamation; Lower GI Tract (stool volume over 24 hours) - Stages 0 = <500 mL, 1 = 500 to 1000 mL, 2 = 1001 to 1500 mL, 3 = >1500 mL, 4 = severe abdominal pain +/- ileus, frank blood, or melena; Liver (bilirubin levels) - Stages 0 = ≤2 mg/dL, 1 = 2.1 to 3 mg/dL, 2 = 3.1 to 6 mg/dL, 3 = 6.1 to 15 mg/dL, 4 = >15 mg/dL.

Time Frame |
---|---|---|
Pharmacokinetics (PK): Time To Maximum Observed Concentration In Plasma (Tmax) Of IV ALXN1007
Time Frame: Predose up to 72 hours postdose
|
The Tmax of ALXN1007 was measured on Treatment Days 1, 28, and 49, from blood samples collected at time points relative to the dosing of ALXN1007. PK assessments were to have been measured from Baseline, Treatment Days 7, 14, 21, 28, 35, 42, 49, 56, and Follow-up Days 86, 180, and Early Termination (ET). Due to the early termination of the study and the clinical development of the ALXN1007 program, a number of PK analyses were not completed. PK data for the 20 mg/kg ALXN1007 once weekly dosing group and the 20 mg/kg ALXN1007 twice weekly dosing group are not available. |

The AUC of ALXN1007 was measured on Treatment Days 1, 28, and 49, from blood samples collected at time points relative to the dosing of ALXN1007. PK assessments were to have been measured from Baseline, Treatment Days 7, 14, 21, 28, 35, 42, 49, 56, and Follow-up Days 86, 180, and Early Termination (ET). Due to the early termination of the study and the clinical development of the ALXN1007 program, a number of PK analyses were not completed.
