In patients undergoing HSCT
In patients undergoing HSCT ORENCIA is the first and only FDA-approved option for prophylaxis of
acute graft versus host disease (aGVHD)1,2
Indication
ORENCIA is indicated for the prophylaxis of acute graft versus host disease (aGVHD), in combination with a calcineurin inhibitor (CNI) and methotrexate (MTX), in adults and pediatric patients 2 years of age or older undergoing hematopoietic stem cell transplantation (HSCT) from a matched or 1 allele-mismatched unrelated-donor.
Patients undergoing HSCT are at risk of developing aGVHD, especially patients undergoing HSCT from a mismatched unrelated donor3
PREVALENCE
~5500HSCT patients are expected
to develop aGVHD each year3
From
30%-70%of HSCT patients develop aGVHD—particularly those from mistreated unrelated donors4
FATALITIES
~16%of HSCT patients experienced fatality caused by aGVHD5
Patients who belong to racial and ethnic minorities may face even greater risk of aGVHD following HSCT from unrelated donors6
This may be due to several factors that impact overall outcome of HSCT, including a lack of donor availability or access to HLA-matched donors and related care.7
Optimally matched (8/8 HLA-matched*) unrelated donors are less available for patients of racial and ethnic minority groups in the United States (US), especially those who are Black or African American.6†
While the likelihood of finding a 7/8 HLA-matched donor‡ is much greater for these patients, it is associated with higher risk of complications and mortality, including aGVHD. Prophylaxis may reduce the risk of aGVHD, making a 7/8 HLA-matched donor a more viable option for many patients from minority backgrounds who cannot find an 8/8 HLA-matched donor.1,4,6
Availability of donors by ethnicity6§
Using 8/8 HLA matching in
Black/African American patients, donor match rates
were as
low as
16%6†
HLA, human leukocyte antigen.
*Matching at HLA-A, HLA-B, HLA-C, and HLA-DRB1 loci.6
†Includes African American, African, Black South or Central American, and Black Caribbean.
‡Mismatching at only one of these loci: HLA-A, HLA-B, HLA-C, or HLA-DRB1.6
§Based on human HLA data for 10,759,087 adult donors spanning 21 US racial and ethnic groups in the National Marrow Donor Program registry in 2012.6
Expanding to 7/8 HLA matching in
Black/African American patients, donor match rates
increased to
at least
66%6†
HLA, human leukocyte antigen.

T-cell activation plays a major role in the mechanism of disease (MOD) of aGVHD8
aGVHD is an immune-triggered process that leads to immune dysregulation and organ dysfunction caused by donor T cells, including damage to the skin, liver, and gastrointestinal tract.9
The interaction of donor T-cells with an antigen-presenting cell promotes the T-cell activation necessary for development of aGVHD.8
HLA, human leukocyte antigen.
*Matching at HLA-A, HLA-B, HLA-C, and HLA-DRB1 loci.6

The mechanism of action (MOA) for ORENCIA inhibits T-cell activation1
ORENCIA has a distinct MOA as an immunomodulator that disrupts T-cell activation—a hallmark of aGVHD pathogenesis.1,8
The relationship of these biological response markers to the mechanisms by which ORENCIA exerts its effects in aGVHD is unknown.1
Ag, antigen; MHC, major histocompatibility complex; TCR, T-cell receptor.
ORENCIA GVHD-1 study design1
The GVHD-1 trial was a multicenter, two-cohort trial evaluating ORENCIA IV (10 mg/kg; 1000 mg maximum dose) in combination with a CNI and MTX, for the prophylaxis of aGVHD. Patients were age 6 years or older who underwent HSCT from a matched or 1-allele—mismatched unrelated donor.
- Cohort 1: 7/8 HLA matching: an open-label, single-arm study of 43 patients who underwent a 7of 8 HLA-matched HSCT
- Cohort 2: 8/8 HLA matching: a randomized (1:1), double-blind, placebo-controlled study of patients who underwent an 8 of 8 HLA-matched HSCT
In both the 7/8 and 8/8 cohorts, ORENCIA was administered as an IV over 60 minutes on the day before transplantation (Day -1), followed by administration on Days 5, 14, and 28 after transplantation.

GVHD-1 efficacy results for ORENCIA, including survival rates1
ORENCIA was studied in patients who received a stem cell transplant from either a matched or 1-allele—mismatched unrelated donor.1
GVHD-1: efficacy at 180 days11
The endpoints/data for 7 of 8 cohort of ORENCIA-treated patients were an exploratory analysis.
*aGVHD-free survival was measured from the date of transplantation until the onset of documented relative grade of aGVHD, or death by any cause up to Day 180 post-transplantation.
ORENCIA + CNI and MTX did not significantly improve Grade III-IV aGVHD-free survival versus placebo + CNI and MTX at Day 180 post-transplantation.1
In an exploratory analysis included in the registrational label:
When used with standard of care (SOC)† with unrelated donors, ORENCIA demonstrated efficacy as a prophylactic option for aGVHD Grades II-IV.1
†SOC for this study was CNI and MTX.
GVHD-1 safety summary for ORENCIA1
Serious adverse reactions reported in >5% of patients who received ORENCIA in combination with a calcineurin inhibitor and methotrexate included pyrexia (20%), pneumonia (8%), acute kidney injury (7%), diarrhea (6%), hypoxia (5%), and nausea (5%).
Permanent discontinuation due to an adverse reaction occurred in two (1.7%) patients due to one case each of pneumonia and allergic reaction.
Most common AEs1
The most common (≥10%) adverse reactions in the ORENCIA-treated patients were anemia, hypertension, CMV reactivation/CMV infection, pyrexia, pneumonia, epistaxis, CD4 lymphocytes decreased, hypermagnesemia, and acute kidney injury. See table.
Adverse reactions (≥10%) in patients with aGVHD who received ORENCIA with a difference between arms of >2% compared to placebo in GVHD-11
AE, adverse event; CI, confidence interval; CMV, cytomegalovirus; IV, intravenous.
ORENCIA GVHD-2 study design1
GVHD-2 was a clinical study using data from the Center for International Blood and Marrow Transplant Research (CIBMTR). The study analyzed outcomes of ORENCIA with a CNI + MTX for the prophylaxis of aGVHD vs a CNI + MTX alone in patients 6 years of age or older who underwent HSCT from a 1-allele—mismatched unrelated donor.
The ORENCIA-treated group (n=54) included 42 patients from GVHD-1 in addition to 12 patients from outside of GVHD-1. The comparator group (n=162) was randomly selected in a 3:1 ratio to the ORENCIA-treated group from the CIBMTR registry to create a more robust comparison. Analyses used propensity score matching and inverse probability of treatment weighting to minimize the impact of selection bias.
Adverse event reporting at the individual level was not feasible in GVHD-2 because of limitations of secondary data collected from the CIBMTR registry. Please see Important Safety Information below.

GVHD-2: efficacy at 180 days1
When used with SOC, ORENCIA demonstrated improved overall survival rates compared to SOC alone.1
Dosing in prophylaxis of aGVHD in adults and pediatric patients aged 2 years and older1
Antiviral prophylaxis treatment
- Before administering ORENCIA, administer recommended antiviral prophylactic treatment for Epstein-Barr virus (EBV) reactivation, and continue for 6 months following HSCT. In addition, consider prophylactic antivirals for CMV infection/reactivation during treatment and for 6 months following HSCT
Intravenous dosing regimen
- For patients 6 years and older, administer ORENCIA 10 mg/kg (maximum dose of 1000 mg) as an intravenous infusion over 60 minutes on the day before transplantation (Day -1), followed by administration on Days 5, 14, and 28 after transplantation
- For patients 2 to less than 6 years old, administer ORENCIA 15 mg/kg as an intravenous infusion over 60 minutes on the day before transplantation (Day -1), followed by 12 mg/kg as an intravenous infusion over 60 minutes on Days 5, 14, and 28 after transplantation
