RGL-305+ Lymphoma + Exploratory Clinical Study

Recruiting now · Not applicable

Conditions studied: Lymphoma Patients With Complete Response (CR) or Partial Response (PR) After Standard Treatment Had a Positive Minimal Residual Lesion (MRD)

In brief

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.

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 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:
• Neutrophil absolute value (ANC) ≥1.0×109/L;
• Platelet count (PLT) ≥80×109/L;
• Hemoglobin (Hb) ≥90g/L;
• International standardized ratio (INR<1.5), activated partial thromboplastin time (APTT) ≤1.5×ULN;
• Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤3 times the upper limit of normal (ULN);
• Total bilirubin (TBIL) ≤1.5×ULN;
• Serum creatinine (Scr) ≤1.5×ULN;
• Left ventricular ejection fraction (LVEF) ≥45%;
• 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)

You may not qualify if…

• 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;
