Lymphoglobuline (equine anti-thymocyte globulin) / Sanofi - LARVOL DELTA

SAFETY PROFILES OF TWO ANTI-THYMOCYTE GLOBULIN FORMULATIONS IN PEDIATRIC HEMATOPOIETIC CELL TRANSPLANTATION: IMPLICATIONS FOR NURSING CARE (EBMT 2026) - "Currently, two main ATG formulations are used in clinical practice: Thymoglobulin® (rabbit-derived anti-human thymocyte immunoglobulin) and Grafalon® (anti-human T lymphocyte immunoglobulin). Grafalon demonstrated a more favorable safety profile during the first 72 hours of ATG infusion compared to Thymoglobuline. Its higher incidence of capillary leak and ICU transfer underscores the need for adequate nursing staffing and training to ensure patient safety. These findings should be interpreted with caution as they are based on preliminary data from a single center; results will be complemented by data from additional centers and multivariate analyses to control for confounding factors."

ATG EXPOSURE AND IMMUNE RECONSTITUTION IN CHILDREN WITH HEMOGLOBINOPATHIES FOLLOWING HSCT: DIFFERENT PATTERNS FOR ATG-GRAFALON AND THYMOGLOBULINE (EBMT 2026) - "Rabbit ATG preparations differ markedly in antibody spectrum and pharmacokinetics (PK), resulting in non-interchangeable exposure–response profiles. Eighty-six pediatric patients (90 HSCTs; 4 re-transplantations; median age 11.13 years) underwent transplantation for hemoglobinopathies (2011–2025) using treosulfan/fludarabine/thiotepa conditioning...In the ATLG cohort, 46.3% also received post-transplant cyclophosphamide (ptCy), which was associated with reduced severe cGvHD without evidence of impaired IR... ATG exposure is a key determinant of IR in pediatric hemoglobinopathy HSCT. ATLG and ATG-T display distinct PK/PD profiles, underscoring the need for individualized, product-specific exposure–response assessment. Weight-based dosing results in substantial variability, particularly in older children."

ULTRA-RAPID CD3/CD45RA-DEPLETED HAPLOIDENTICAL HSCT FOR PEDIATRIC CEREBRAL ALD: FEASIBILITY, ENGRAFTMENT KINETICS, CHIMERISM BEHAVIOR, AND EARLY NEUROLOGIC OUTCOMES IN THREE CASES (EBMT 2026) - "In parallel, lentiviral gene therapy (elivaldogene autotemcel) is an option for select early-stage patients, but eligibility, access, and time-to-treatment constraints frequently limit real-world use relative to the pace of inflammatory progression...Conditioning comprised ALC-based Thymoglobuline, model-based Fludarabine and Busulfan, Rituximab, and IVIG; GVHD prophylaxis included Tacrolimus... A standardized CD3/CD45RA-depleted haploidentical platform enabled rapid time-to-transplant, ultra-fast engraftment, and low GVHD in pediatric cALD. The recurrent observation of mixed/declining chimerism in early-stage patients—despite robust initial engraftment—highlights a potentially stage- and platform-specific behavior that may benefit from protocolized monitoring and timely DLI. These data support haploidentical HSCT as a timely, feasible option for cALD for multicenter evaluation to refine conditioning intensity, graft composition, and DLI strategies to optimize durable..."

OUTCOMES OF ALLOGENEIC HSCT IN NIJMEGEN BREAKAGE SYNDROME WITH TREOSULFAN-BASED CONDITIONING REGIMEN - A MULTICENTER STUDY (EBMT 2026) - "We recently demonstrated experience of treosulfan 30g/m2 versus low doses of busulfan...All received fludarabine 150mg/m2, 24 cyclophosphamide (22–40mg/kg, 1–30mg/kg, 1–20mg/kg). In 37 patients, rabbit ATG (thymoglobulin, Genzyme) 3-7,5mg/kg, in 1 patient horse ATG (ATGAM) 100mg/kg, and in 2 patients no serotherapy was used.In 25 patients matched unrelated (19–10/10, 6–9/10 HLA-matched), in 9 mismatched related, in 6 matched sibling donor was used... Both doses of treosulfan 21g/m2 and 30g/m2 were well tolerated by NBS patients. However, lower dose of 21g/m2 was associated with higher risk of mixed chimerism and leukemia relapse versus increased incidence of secondary malignancy after higher dose of 30g/m2."

HUMANIZED ANTI‑CD25 MONOCLONAL ANTIBODY FOR GVHD PROPHYLAXIS IN ELDERLY HAPLOIDENTICAL ALLOGENEIC STEM CELL TRANSPLANTATION: A PHASE II STUDY (EBMT 2026) - P2 | "The standard GVHD prophylaxis protocol includes rATG+CNI+short-term MTX+mycophenolate mofetil. Patients in experimental group received humanized anti-CD25 mAb (50 mg/day, +1d, +4d) and reduced rATG (8mg/kg, Thymoglobuline)... Our study revealed that the addition of short‑course anti-CD25 prophylaxis (day +1, +4) in the rATG system proved feasible and safe. However, we did not observe its significant advantage in reducing severe acute or chronic GVHD. The benefit of extensive administration of anti-CD25 mAb warrants further investigation."

Thymoglobuline and grafalon show comparable transplant outcomes in patients with aplastic anemia undergoing allogeneic stem cell transplantation: A multicenter EBMT saawp study of 1603 patients (ASH 2025) - "Introduction:Rabbit anti-thymocyte globulin (ATG) is a key component of conditioning regimens for patients withaplastic anemia (AA) undergoing allogeneic hematopoietic stem cell transplantation (HSCT).Thymoglobuline (Thymo) is widely regarded as the standard formulation due to its extensive clinicaladoption and inclusion in international guidelines, while Grafalon (Grafa) is also commonly used inclinical practice. In this large, registry-based cohort of AA patients undergoing HSCT, no significant differences wereobserved in OS, GF, GVHD incidence, or GRFS between Thymo and Grafa. However, Grafalon dosageappeared to influence outcomes, particularly with respect to chronic GVHD. These findings support theclinical equivalence of both rabbit ATG formulations in the setting of HSCT and suggest that ATG selectioncan be guided by institutional preference or availability without compromising patient outcomes."

The impact of HLA loss of heterozygosity on outcome after haploidentical hematopoietic stem cell transplantation in hematological malignancies (ASH 2025) - "Allpatients received haplo-HSCT; pre-transplant disease status was CR (80.0%, n=36) or NR (20.0%, n=9).Conditioning regimens were busulfan (Bu)-cyclophosphamide (Cy) (66.7%), total body Irradiation (TBI)-Cy(17.8%), Bu-fludarabine (flu) (13.3%), or TBI-flu (2.2%). ATG-fresenius (ATG-F) or ATG-thymoglobuline(ATG-T) were used for GVHD prophylaxis... Second transplantation improves survival in patients experiencing relapse following haplo-HSCT who demonstrate HLA loss. Survival outcomes were independent of HLA loss pattern (haplotype vs.locus-specific) or extent (number of loci lost). Poor prognostic factors were pre-transplant NR status andthe use of TBI-based conditioning."

Decreased Chronic GvHD with Post-Transplant Cyclophosphamide (PTCY) Compared to ATG in Patients with Myelofibrosis Allografted with Unrelated Donor: A Study from the Chronic Malignancies Working Party of the EBMT (ASH 2024) - "Background Prospective randomized trials have reported a benefit for anti-thymoglobuline (ATG)-based graft-versus-host disease (GvHD) prophylaxis in the setting of allogeneic hematopoietic stem cell transplantation (alloHSCT) using unrelated donors (UD)...Cox (cause-specific) proportional hazards models were used to obtain adjusted estimates of the effect of PTCY compared to ATG on all endpoints, with a predefined set of adjustment factors (age, DIPSS, donor HLA matching, prior ruxolitinib, comorbidity score, MF subtype (PMF vs sMF)) and a frailty term for transplant center...PTCY is a valid option and considering availability and costs of ATG this may offer a good choice/alternative for regions which do have difficulties to have access to ATG. However, engraftment remains an issue in this setting."

DOES THE TIME OF ANTI-THYMOCYTE GLOBULIN ADMINISTRATION AFFECT UNRELATED DONOR ALLO-HCT OUTCOMES? A RETROSPECTIVE ANALYSIS ON BEHALF OF THE POLISH ADULT LEUKEMIA GROUP (EBMT 2025) - "Background: Rabbit anti-thymocyte globulin (r-ATG) has a pivotal role in preventing graft-versus-host disease (GvHD) in unrelated allo-HCT. Thymoglobuline (ATG-T, formerly Genzyme) forms one of the most widely utilized r-ATG formulations... Our findings suggest that the ATG-T administration scheme and ATG-T exposure may significantly influence allo-HCT outcomes. The prolonged ATG-T persistence after donor T-cell infusion in the ATG-Tf group, which likely led to greater donor T-cell depletion, resulted in a significantly lower incidence of aGvHD and higher 5-year OS compared to ATG-Tp with similar infection rates and conditioning regimens.Given the limitations of our study, including a small sample size and donor type heterogeneity, these results warrant confirmation in larger, prospective, double-blind randomized trials with more homogeneous cohorts.
