Graft failure has occurred after TREGZI administration [see Adverse Reactions (6.1)]. Screen TREGZI recipients for antidonor antibodies that may prevent engraftment. Monitor patients closely for laboratory evidence of hematopoietic recovery.
Acute and chronic Graft-Versus-Host disease (GVHD), including life-threatening and fatal cases, occurred following treatment with TREGZI [see Adverse Reactions (6.1)]. Acute GVHD manifests as maculopapular rash, gastrointestinal symptoms, and elevated bilirubin. Chronic GVHD may include skin rash, mouth sores, dry eyes, liver inflammation, and development of scar tissue in the skin and joints and damage to the lungs. Treat patients with a single agent calcineurin inhibitor as prophylaxis to decrease the risk of GVHD. Monitor for signs and symptoms of GVHD, and treat if GVHD develops.
Infusion reactions (IRs) may occur during or following treatment with TREGZI. Serious hypersensitivity reactions including anaphylaxis may occur due to DMSO, human serum albumin (HSA), Dextran or murine protein present in TREGZI. IRs may begin within minutes of the start of TREGZI infusion, although symptoms may continue to intensify and not peak for several hours after the completion of the infusion. Monitor patients for signs and symptoms of IRs during and after TREGZI administration. When a reaction occurs, pause the infusion and institute supportive care as needed. Premedicate patients with antipyretics and histamine antagonists prior to infusion to reduce the incidence and intensity of infusion reactions.
Secondary malignancies and malignancies of donor origin may occur following treatment with TREGZI [see Adverse Reactions (6.1)]. Development of secondary malignancies, including posttransplantation lymphoproliferative disorder (PTLD) may occur many years after transplantation. PTLD manifests as a lymphoma-like disease favoring non-nodal sites. PTLD is usually fatal if not treated. Serial monitoring of blood for EBV DNA may be warranted in patients with persistent cytopenias. No patient treated with TREGZI has developed PTLD. Monitor for malignancies of donor origin and secondary malignancies.
Contact Orca Bio at 1-877-290-6722 if any patient is diagnosed with a secondary malignancy or a malignancy of donor origin.
Transmission of serious infectious or communicable disease or agents may occur with TREGZI treatment as it is derived from human donor blood and manufactured using animal-derived reagents. Risks of transmission of infectious agents may occur despite screening or testing of donors. Risks of transmission of serious infections include, but are not limited to, human immunodeficiency virus, human T cell lymphotropic virus (HTLV)-1 and -2, hepatitis B virus (HBV), hepatitis C virus (HCV), Treponema pallidum, Trypanosoma cruzi, West Nile virus (WNV), cytomegalovirus, transmissible spongiform encephalopathy agents and vaccinia. Monitor patients for signs and symptoms of infections, perform tests for infectious agents and treat as clinically indicated.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety data described in this section reflects exposure to TREGZI in one clinical study (Precision-T Study) which enrolled patients with advanced hematologic malignancies eligible for HLA-matched allogeneic stem cell transplantation following myeloablative preparative regimen. The study treated 88 patients with TREGZI and 94 patients with standard of care (SoC) unmanipulated graft. The patients were followed for a duration of 24 months [see Clinical Studies (14)].
Serious adverse reactions within the first 100 days occurred in 25 patients (28%) treated with TREGZI including bacterial infections (n=12; 14%), pyrexia (n=4; 5%), venooclusive liver disease (n=3; 3%), and viral infections (n=3; 3%). Fatal adverse reactions occurred in 3 patients (3%).
Non-relapse deaths at 12 months occurred in 3/88 (3.4%) patients in the TREGZI group and in 11/94 (11.7%) patients in the SoC control group [see Clinical Studies (14)].
In the TREGZI treated safety population, the most common (greater than or equal to 10%) Grade 3 or 4 nonlaboratory adverse reactions were mucositis (28%), bacterial infection (18%), infection – pathogen unspecified (18%), and viral infection (14%).
Table 3 summarizes the most common nonlaboratory adverse reactions occurring in ≥10% patients treated with TREGZI or unmanipulated allograft control group in Precision-T Study.

Risk Summary
There are no available data on TREGZI use in pregnant women. No animal reproductive and developmental toxicity studies have been conducted with TREGZI to assess whether it can cause fetal harm when administered to a pregnant woman. It is not known if TREGZI has the potential to be transferred to the fetus. TREGZI should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Report all pregnancies following treatment with TREGZI to Orca Bio at 1-877-290-6722.
In the United States (U.S.) general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Risk Summary
There are no available data on the presence of TREGZI in human milk, the effect on the breastfed infant, or the effects on milk production.
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for TREGZI and any potential adverse effects on the breastfed infant from TREGZI or from the underlying maternal condition.
Pregnancy Testing
Females of reproductive potential should have a pregnancy test prior to starting the conditioning regimen for TREGZI.
Contraception
There are insufficient exposure data to provide a recommendation concerning the duration of contraception following treatment with TREGZI. See the prescribing information of selected myeloablative regimens for recommendations on use of contraception.
Infertility
There are no data on the effect of TREGZI on fertility.
Safety and efficacy of TREGZI in pediatric patients have not been established.
Although Precision-T Study did not include any patients aged 65 years and older, some patients over 65 years of age participated in other TREGZI studies using a myeloablative or reduced intensity conditioning (RIC) regimen. However, the number of patients was inadequate to allow subgroup analysis to support recommendations in the geriatric population.
TREGZI (allogeneic regulatory T cell immunotherapy with HSPC and T cells-vldq) is an allogeneic hematopoietic stem cell and T-cell immunotherapy isolated from the mobilized peripheral blood of an 8/8 HLA-matched related or unrelated donor and is donor- and recipient-specific.
TREGZI is composed of individual cell suspensions for intravenous infusion of 1) purified hematopoietic stem and progenitor cells (HSPCs), 2) regulatory T cells (Tregs), and 3) conventional T cells (Tcons). In addition, 4) a chemically defined diluent is provided to dilute the Tcons before infusion.
The HSPC, Treg and Tcon suspensions must pass a rapid microbial detection test prior to administration. Complete sterility test results are available approximately 14-days post-administration. The Tcon diluent must pass a sterility test before release for shipment.
TREGZI is isolated from the mobilized peripheral blood of a donor HLA-matched to the recipient, and administered after appropriate cytoreductive conditioning. TREGZI contains purified regulatory T cells (Tregs) and conventional T cells (Tcons). The exact mechanism by which Tregs exert their effects is not fully understood. Tregs are administered prior to Tcons to control GVHD and promote immune reconstitution. Nonclinical studies have shown that Tregs suppress Tcon activation and proliferation in secondary lymphoid organs and GVHD target organs, and improve immune reconstitution without compromising graft-versus-tumor (GVT) effects of Tcons. The immunosuppressive activity of Tregs occurs through various immunoregulatory mechanisms, which help preserve immune function and decrease severity of GVHD. Tcons are administered approximately two days later to accelerate immune reconstitution, characterized by the complete or partial restoration of peripheral blood T-cell counts. Immune reconstitution is thought to result in graft-versus-infection and graft-versus-leukemia effects.
TREGZI also contains allogeneic hematopoietic stem and progenitor cells (HSPCs). HSPCs home to the bone marrow, engraft, self-renew, proliferate, and differentiate into all mature blood cells. The mature cells are released from the bone marrow, circulate in the blood stream, and migrate to tissue sites, restoring blood counts and hematopoietic function.
No studies have been conducted to evaluate the pharmacodynamics of TREGZI.
No studies have been conducted to evaluate the pharmacokinetics of TREGZI.
No nonclinical studies were performed to evaluate the effect of TREGZI on carcinogenesis, mutagenesis, or impairment of fertility.
The efficacy of TREGZI was evaluated in a multicenter, open-label, randomized, controlled study (Phase 3 Precision-T Study; NCT05316701). The study enrolled adult patients with 1) acute leukemias (acute lymphoblastic leukemia [ALL], acute myelogenous leukemia [AML], or mixed phenotype/ undifferentiated) in complete remission (CR) or CR with incomplete recovery (CRi) or 2) myelodysplastic syndrome (MDS): i) with ≤10% blast burden in the bone marrow and who were eligible for allogeneic transplant per 2017 International Expert Panel recommendations1 including high-risk IPSS-R≥5, or poor risk genetic features, or failed nontransplant therapies including erythropoietin-stimulating agents (ESAs), lenalidomide, hypomethylating agents (HMAs), or intensive chemotherapies or ii) therapy-related/secondary MDS as defined by the World Health Organization (WHO) classification of myeloid malignancies. Patients with prior history of allogeneic hematopoietic stem cell transplantation were excluded.
In total, 187 patients were randomized to receive either TREGZI (n=93) in the treatment group or an unmanipulated allograft in the control group (n=94). Of the 93 patients randomized to TREGZI, 88 patients were treated with TREGZI. The reasons for not receiving TREGZI were as follows: One patient received cryopreserved SoC alloHCT because of COVID, 2 patients withdrew consent prior to treatment, 1 patient relapsed and did not enter remission, and 1 patient received TREGZI after the data cutoff date. The median (min, max) time from randomization to transplant is 9 days (6, 26) for patients who received TREGZI (N=88) and 8 days (6, 24) for patients who received SoC (N=94). Both TREGZI and the unmanipulated allograft were derived from G-CSF-mobilized peripheral blood apheresis product from 8/8 (at alleles A, B, C, and DRB1) HLA-matched sibling donors (MSD) or unrelated donors (MUD) and were administered after a myeloablative preparative regimen such as total body irradiation (TBI)-based or chemotherapy-based options. Patients in the TREGZI group received HSPC and Treg components on Day 0, Tcon component on Day 2 or 3 (if no evidence of uncontrolled bacterial, viral, or fungal infection and Karnofsky performance score ≥30%) and tacrolimus within 12 hours after T con infusion as GVHD prophylaxis. Patients in the control group received unmanipulated allograft on Day 0 and tacrolimus starting on Day-3 and methotrexate starting on Day 1 as GVHD prophylaxis.
The population demographics and characteristics were as follows: The median age was 44 years (range: 19 to 65 years), 103 patients (55%) were male, 139 patients (74%) were white, 18 patients (10%) were Asian, 3 patients (2%) were black, 3 patients (2%) American Indian or Alaskan Native, 2 patients (1%) were Native Hawaiian or Other Pacific Islander, and 22 patients (12%) had race not reported. The primary disease diagnoses were as follows: 57 patients (31%) with ALL, 100 patients (54%) with AML, 23 patients (12%) with MDS, and 7 patients (4%) with mixed phenotype acute leukemia (MPAL). Patients received the following myeloablative preparative regimen: 58 patients (31%) received TBI-based conditioning regimens, 126 (67%) received Busulfan-Fludarabine -Thiotepa conditioning regimens, 3 patients (2%) did not receive any conditioning regimen and treatment. DRI score was high in 36 patients (19%) and intermediate in 151 patients (81%). Baseline HCT-CI score were as follows: 45 patients (24%) were with score 0, 90 patients (48%) were with score 1-2, and 52 patients (28%) were with score 3-5. Ninety-five patients (51%) received a graft from 8/8 HLA matched sibling and 92 patients (49%) received a graft from 8/8 HLA matched unrelated donor. The demographics, disease characteristics, conditioning regimens, DRI score, HCT-CI score, and graft source were balanced between TREGZI group and the control group.
The primary efficacy endpoint was cGVHD-free survival (cGFS), defined as the time from HCT to death by any cause or moderate to severe cGVHD, as graded per National Institutes of Health [NIH] consensus criteria and determined by an independent review committee. To control the Type I error rate, other efficacy endpoints were tested in the following hierarchical order: time to moderate/severe chronic GVHD (cGVHD), overall survival (OS), and GVHD-free/relapse-free survival (GRFS).
The study demonstrated a statistically significant improvement in cGFS and time to moderate/severe cGVHD in patients randomized to TREGZI compared with patients randomized to control. Table 5 and Figure 1 below summarize the efficacy results from Precision-T Study.

Figure 1: Kaplan-Meier Curve of cGFS in Precision-T Phase 3 (Intention-to-Treat Analysis Set)
The median duration of follow up was 8.48 (range: 0 to 22.2) months on the TREGZI arm and 9.03 (range: 0 to 20.3) months on the control arm.
At 12 months, the Kaplan-Meier estimate of cGFS was 78.0% (95% CI: 65.0%, 86.6%) for TREGZI compared with 38.4% (95% CI: 26.2%, 50.5%) for the control group.
Seven patients (7.5%) in the TREGZI group and 15 patients (16.0%) in the control group died on study with a median follow-up for survival of 11.04 (range: 0.2 to 23.9) months and 11.47 (range: 0.7 to 24.3) months, respectively.
Fifteen patients (16.1%) in the TREGZI group and 10 patients (10.6%) in the control group relapsed on study.
All 88 patients (100%) treated with TREGZI achieved a neutrophil count of 500/mm3 within 28 days of infusion. Of these, 53 patients (60.2%) had neutrophil counts greater than 500/mm3 on three consecutive days, confirming neutrophil recovery within 28 days of infusion.
Myeloid-lineage donor chimerism data were available for 68 of 88 patients treated with TREGZI. Among these 68 patients, all demonstrated myeloid-lineage donor chimerism >95% at Day +28 post-transplant.
