RGL-305+ Lymphoma + Exploratory Clinical Study

An Exploratory Clinical Study to Evaluate the Safety and Cytodynamic Characteristics of RGL-305 in Patients With Lymphoma


Sponsor

Fudan University

Enrollment

12 participants

Start Date

Apr 21, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

This study is an open, prospective, dose-increasing exploratory clinical trial. To evaluate the safety, cytodynamics and initial efficacy of RGL-305 in patients with lymphoma. All enrolled lymphoma patients were required to achieve CR or PR and MRD positive after standard treatment, PR patients were required to have a Deauville score of 4, and all patients would receive RGL-305 cell reinfusion therapy.


Eligibility

Min Age: 18 YearsMax Age: 75 Years

Inclusion Criteria17

  • Voluntarily participate in the study and sign a written informed consent
  • Age 18-75 years old (including the boundary value), gender is not limited;
  • Patients with pathologically confirmed lymphoma who have previously received at least one standard treatment. After the last treatment, patients with Lugano 2014 lymphoma efficacy evaluation criteria were CR or PR, and MRD was positive. Patients with PR were required to have a Deauville score of 4.
  • Be willing to provide blood or tissue samples required for cytodynamic and biomarker detection before and after treatment;
  • ECOG score is 0 or 1;
  • Expected survival ≥3 months;
  • The function of vital organs meets the following criteria:

  • Electrocardiogram: Fridericia corrected QT interval (QTcF) \<470 ms; The QTc interval must be corrected according to Fridericia's standard with the correction formula QTcF=QT/RR\^0.33.
  • Fertile female subjects must agree to effective contraception and refrain from egg donation for 6 months from the signing of the informed consent until the last administration of the investigational drug, the serum pregnancy test must be negative within 7 days prior to the first administration, and they are not lactating; Male subjects whose partner is a fertile woman must agree to highly effective contraception and refrain from sperm donation from signing the informed consent until 6 months after the final administration of the investigational drug (see Annex 6 for details)

Exclusion Criteria17

  • Have previously received or planned to undergo organ transplantation or allogeneic stem cell or allogeneic bone marrow transplantation;
  • Combined with congenital or acquired immunodeficiency such as cellular immunodeficiency (e.g., DiGeorge syndrome, T-negative severe combined immunodeficiency \[SSCID\]) or combined T-cell and B-cell immunodeficiency (e.g., T-and B-negative combined immunodeficiency, Wiskott-Aldrich syndrome, ataxic telangiectasia, often) See variable immune deficiency); Or infected with human immunodeficiency virus (HIV);
  • The presence of autoimmune diseases, except for patients with hypothyroidism due to autoimmune thyroiditis who only need hormone replacement therapy;
  • History of epilepsy or other central nervous system diseases, or lymphoma invading the central nervous system;
  • Complicated with other malignant tumors, except malignant tumors with disease-free survival of more than 3 years and carcinoma in situ;
  • History of allergy to blood products, known to be allergic to test substances;
  • Any non-hematological toxicity associated with previous treatment does not return to ≤ grade 1, except for hair loss and peripheral neurotoxicity;
  • Those who had undergone major surgery (≥ Grade 3 surgery) within 4 weeks before the start of study treatment, or who required elective surgery during the trial period;
  • Have an poorly controlled or severe cardiovascular disease, such as symptomatic congestive heart failure (NYHA class III or IV), a myocardial infarction within 6 months prior to study initiation, or unstable angina within 1 month prior to study initiation, or an arrhythmia requiring treatment or intervention, Or hypertension remains poorly controlled after adequate treatment (systolic blood pressure ≥150mmHg, diastolic blood pressure ≥90mmHg);
  • Known hereditary or acquired bleeding or thrombotic tendencies;
  • Subjects with a known or highly suspected history of interstitial pneumonia, or evidence of active interstitial pneumonia on chest CT during the pre-screening period; Known history of idiopathic pulmonary fibrosis, institutional pneumonia (such as bronchiolitis obliterans or cryptogenic institutional pneumonia); Subjects who may interfere with the detection or management of suspected drug-related pulmonary toxicity;
  • A severe infection occurring within 28 days prior to study initiation (such as intravenous antibiotics, antifungal, or antiviral drugs as required by clinical practice), or an active infection receiving therapeutic intravenous or oral antibiotics within 14 days prior to study initiation, or an unexplained fever;
  • Active hepatitis B (HBV), hepatitis C (HCV), cytomegalovirus (CMV), EB virus (EBV), HIV, syphilis infection;

Interventions

DRUGRGL-305

RGL-305 is administered intravenously with a recommended rate of 3-5 mL /min. The interval after the first administration was 3 weeks, and then every 2 weeks was a cycle, each cycle was given d1, and up to 5 cycles of cell transfusion were received.
