Allo-HSCT Vs. Auto-HSCT for PTCL Patients With PR After First-line Systemic Therapy : A Prospective, Multicenter, Cohort Study-(T-START-PR)

Recruiting now

Conditions studied: Peripheral T Cell Lymphoma

In brief

This study is a multicenter, two-arm, prospective clinical trial, comprising two groups: the allogeneic hematopoietic stem cell transplantation group (Allo-HSCT) and the autologous hematopoietic stem cell transplantation group (Auto-HSCT). It aims to evaluate the efficacy and safety of Auto-HSCT and Allo-HSCT in the treatment of peripheral T-cell lymphoma that has achieved partial response (PR) after first-line therapy. During the screening/baseline period, informed consent will be obtained, and inclusion/exclusion criteria will be verified. Group assignment (Allo-HSCT vs. Auto-HSCT) will be determined taking into account the availability of a matched donor and the patient's preference. The study plans to enroll 44 patients in the allogeneic hematopoietic stem cell transplantation group, while all concurrent patients undergoing autologous stem cell transplantation will be included in the other group for inverse probability weighting analysis. Data on demographics and medical history will be collected, and assessments including vital signs, physical examination, PET-CT, bone marrow aspiration smear, flow cytometry, and bone marrow pathology will be performed.

Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age \& Sex:
• Males or females aged 18 to 70 years (inclusive).
• ECOG performance status score of 0 to 1, with no deterioration within the last two weeks.
• Expected survival period greater than 12 weeks.
• Patients must have a histopathological confirmation of PTCL according to the 2016 revised WHO classification of lymphoid neoplasms (Swerdlow SH et al. 2016). Eligible histological subtypes are limited to the following:
• Peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS)
• Anaplastic large cell lymphoma, ALK-negative (ALK-ALCL)
• Follicular helper T-cell lymphoma or PTCL with TFH phenotype (FTCL or PTCL-TFH)
• Patients undergoing allogeneic hematopoietic stem cell transplantation must have a suitable stem cell donor:
• (i) Related donors must be at least 5/10 matched for HLA-A, -B, -C, -DQB1, and -DRB1.
• (ii) Unrelated donors must be at least 8/10 matched for HLA-A, -B, -C, -DQB1, and -DRB1.
• Patients must have achieved a partial response (PR) as per the Lugano 2014 response criteria for lymphoma after six cycles of CHOP, BV-CHP or CHOP-like chemotherapy.
• Hematopoietic Cell Transplantation-Comorbidity Index (HCT-CI) score ≤ 2.
• Adequate hepatic, renal, cardiac, and pulmonary function, defined as follows:
• Hepatic function: Serum total bilirubin ≤ 2 × upper limit of normal (ULN) (≤ 3.0 × ULN in cases of Gilbert's syndrome or baseline hepatic involvement); alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 × ULN (≤ 5.0 × ULN in cases of hepatic involvement).
• Renal function: Serum creatinine ≤ 1.5 × ULN, or creatinine clearance ≥ 50 mL/min as calculated or measured by the Cockcroft-Gault method.
• Cardiac function: Left ventricular ejection fraction (LVEF) ≥ 50% as measured by multigated acquisition (MUGA) scan or echocardiography (ECHO).
• Baseline oxygen saturation > 92%.
• Pulmonary function: Diffusing capacity of the lung for carbon monoxide (DLCO) (hemoglobin-corrected) ≥ 40% and forced expiratory volume in 1 second (FEV1) ≥ 50%.

You may not qualify if…

• Ann Arbor clinical stage I disease.
• History of malignancy within the past 5 years, except for locally curable malignancies that have been treated with curative intent (e.g., basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast).
• Active infection, including:
• Known active or latent tuberculosis, evidenced by a positive tuberculin (PPD) skin test (induration >10 mm or per local criteria for a positive result) or radiographic findings suggestive of active/latent TB on chest X-ray/CT.
• Known history of infection with Human Immunodeficiency Virus (HIV) and/or AIDS.
• Chronic active hepatitis B or hepatitis C infection:
• <!-- -->
• Patients positive for hepatitis B virus (HBV) DNA are excluded; however, those with undetectable HBV DNA levels are eligible. The upper limit of normal (ULN) for HBV DNA shall be based on the reference values of each participating center.
• Patients positive for hepatitis C virus (HCV) RNA are excluded; however, those with undetectable HCV RNA are eligible. The ULN for HCV RNA shall be based on the reference values of each participating center.
• (d) Active viral infections other than hepatitis B or hepatitis C (e.g., herpes zoster, cytomegalovirus).
• (e) Infection requiring intravenous antimicrobial therapy, associated with hemodynamic instability, worsening or new onset of infectious signs/symptoms, or new infectious foci on imaging; or persistent fever without localizing signs that cannot rule out infection.
• (f) Positive serum DNA test for Epstein-Barr virus (EBV).
• Poorly controlled cardiac symptoms or disease, such as:
• i. Heart failure greater than New York Heart Association (NYHA) class II. ii. Unstable angina. iii. Myocardial infarction within the past year. iv. Clinically significant supraventricular or ventricular arrhythmia requiring treatment or intervention.
• Pregnant or lactating women, and subjects of childbearing potential unwilling to use effective contraception.
• Psychiatric illness or individuals unable to provide informed consent.
• PTCL patients with central nervous system involvement.
• PTCL patients who have previously received PD-1 inhibitor therapy.
• Any other condition that, in the judgment of the investigator, would make the subject unsuitable for participation in this study.
