New hope for tough lymphoma: drug combo trial launches

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Met the criteria of relapsed/refractory lymphoma: Relapsed lymphoma was defined as relapsed lymphoma more than 6 months after achieving complete remission (CR) after initial chemotherapy. Refractory lymphoma was defined as any of the following criteria: 1) tumor shrinkage \< 50% or disease progression after at least 4 courses of standard chemotherapy; 2) achieved CR with standard chemotherapy, but relapsed within half a year; 5. ECOG performance status score: 0-2; 6. Expected survival time ≥3 months; 7. There must be at least one measurable or evaluable lesion that meets the Lugano 2014 criteria for lymphoma: 1)Measurable lesion: Nodal lesions with major diameter greater than 1.5cm and minor diameter greater than 1.0cm as assessed by PET/CT or Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI); Or the length of extranodal lesions \>1.0cm; 2)Evaluable lesions: PET-CT showed increased uptake in lymph nodes or extranodal regions (higher than liver) and imaging features consistent with lymphoma; 8.Have adequate organ and bone marrow function, defined as follows: 1. Blood routine: absolute neutrophil count (ANC) ≥ 1.5×109/L(≥1.0×109/L in patients with bone marrow involvement); platelet count (PLT) ≥ 75×109/L(≥50×109/L in patients with bone marrow involvement), hemoglobin (HGB) ≥ 8.0 g/dL; The patients had not received granulocyte growth factor, platelet transfusion, or red blood cell transfusion within 14 days before the examination; 2. Liver function: serum total bilirubin (TBIL) ≤1.5× upper limit of normal value (ULN, liver invasion ≤3.0×ULN); alanine aminotransferase (ALT) and aspartate transferase (AST) ≤2.5×ULN (liver invasion ≤5.0×ULN); 3. Renal function: serum creatinine (Cr) ≤1.5×ULN. 4. Coagulation function: International Normalized Ratio (INR) ≤1.5 × ULN; Prothrombin Time (PT), Activated PartialThromboplastin Time (APTT) ≤1.5×ULN (unless the subject is receiving anticoagulant therapy, And PT and APTT at screening were within the expected range for anticoagulant therapy). 5. Thyroid stimulating hormone (TSH) or free thyroxine (FT4) or free triiodothyronine (FT3) within the normal range ±10% (Note: non-autoimmune causes of abnormal TSH, FT3 and FT4 can be maintained in the normal range after replacement treatment of hypothyroidism can be enrolled). 9.Patients who had received previous antineoplastic therapy could not be enrolled until the toxicity of previous treatment returned to the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 grade score ≤1 or the baseline level; 10.Women of childbearing potential must have a negative serum pregnancy test within 7 days before the first dose of medication; Effective contraception should be used from the time of informed consent until 6 months after the last dose of study drug. Exclusion Criteria: 1. Patients with hemophagocytic lymphohistiocytosis; 2. Patients with active infection or with obvious B symptoms and high fever should be excluded according to the comprehensive judgment of the investigators; 3. The subject's previous history of antineoplastic therapy meets one of the following conditions: 1. Failure to achieve CR or PR after previous treatment with mitoxantrone or mitoxantrone liposome, or relapse within 6 months after treatment; 2. Prior treatment with anthracyclines or anthraquinones and cumulative dose of doxorubicin \> 550 mg/m2 (liposomal doxorubicin \> 2000 mg/m2, epirubicin \> 1000 mg/m2, pirarubicin \> 1000 mg/m2, mitoxantrone \> 160 mg/m2); 3. Received anti-tumor treatment (including chemotherapy, targeted therapy, traditional Chinese medicine with anti-tumor activity, etc.) or participated in other clinical trials and received clinical trial drugs within 4 weeks or 5 half-lives (whichever came first) before the first use of the study drug; 4. patients who received autologous hematopoietic stem-cell transplantation or allogeneic hematopoietic stem-cell transplantation within 100 days of the first dose of treatment; 4. Hypersensitivity reaction to any study drug or its components; 5. Patients with known allergy to any component of the monoclonal antibody; 6. Patients with a known history of Human Immunodeficiency Virus (HIV) infection and/or acquired immunodeficiency syndrome; 7. Patients with active chronic hepatitis B or active hepatitis C. Hepatitis B SurfaceAntigen (HBsAg) or hepatitis B core Antibody (HBcAb) or Hepatitis C Virus (HCV) during the screening period HCV) antibody positive patients must be further tested for Hepatitis B Virus (HBV) DNA (no more than 1000 copies /mL or 500 IU/mL) and HCV RNA (no more than the lower limit of detection of the assay), Enrollment in the trial occurred after the exclusion of patients with active hepatitis B or hepatitis C infection requiring treatment. Hepatitis B virus (HBV) carriers, medically stable hepatitis B (DNA \> 1000 copies /mL or 500IU/mL) and cured hepatitis C patients are eligible for enrollment. 8. Cardiac function and disease is one of the following: 1. long QTc syndrome or QTc interval \>480 ms; 2. complete left bundle branch block, degree II or III atrioventricular block; 3. severe, uncontrolled arrhythmia requiring medical treatment; 4. New York College of Cardiology grade ≥ III; 5. cardiac ejection fraction (LVEF) less than 50%; 6. a history of myocardial infarction, unstable angina, major unstable ventricular arrhythmia or any other arrhythmia requiring treatment, a history of clinically significant pericardial disease, or electrocardiographic evidence of acute ischemic or active conduction system abnormalities within 6 months before recruitment; 9. Receive live attenuated vaccine (except influenza vaccine) within 4 weeks before enrollment or during the study period; 10. Previous or current concurrent cancer (except for effectively controlled non-melanoma basal cell carcinoma of the skin, breast/cervical carcinoma in situ, and other malignancies that have been effectively controlled without treatment within the previous five years); 11. Those with central nervous system involvement; 12. Lactating women; 13. Subjects receiving systemic glucocorticoid therapy or other immunosuppressive therapy for a condition within 14 days before starting study treatment (topical, ocular, intra-articular, nasal, and inhaled glucocorticoids were allowed (minimal systemic absorption); Short-term (≤ 7 days) use of glucocorticoids was permitted for preventive treatment (e.g., contrast allergy) or for the treatment of nonautoimmune conditions (e.g., delayed hypersensitivity from contact allergens). 14. Had undergone major surgery within 28 days before starting study treatment, or had undergone radiation therapy within the previous 90 days.
