Details and patient eligibility

About

Phase I portion of this study will evaluate the efficacy and saftey of toripalimab plus rituximab in treating untreated elderly diffuse large B cell lymphoma patients.
The aim of phase II portion of this study will evaluate the efficacy and saftey of toripalimab plus rituximab followed by R-CHOP(rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) regimen in treating untreated elderly diffuse large B cell lymphoma patients.

Full description

The study consisted of a phase I and II portion. In phase I, patients accepted at least 2 cycles of toripalimab plus rituximab. Another 2 cycles of toripalimab plus rituximab will offered if they achieved CR. In phase II, all patients accpet R-CHOP regimen. If patient get CR after, they will accept 4 cycles of R-CHOP regimen, patients with PR,SD or PD will accept 6 cycles of R-CHOP.

Aged 60-75 years old male or female;
Untreated,without any anti-lymphoma treatment;
DLBCL, or follicular lymphoma grade 3B, or transformed DLBCL, EBV (+) DLBCL, ALK (+) DLBCL, high-grade lymphoma were confirmed by histopathology examination;
Clinical stage II-IV, or stage I with bulky diesase (diameter > 7.5 cm);
International Prognostic Score (IPI): 2-5;
Paraffin tissue specimens or fresh puncture tissue specimens are available;
Eastern cooperative oncology group score: 0-2;
Estimated survival ≥ 12 months;
There must be at least one evaluate able or measurable lesion that meets the Lugano 2014 Lymphoma criteria [evaluable lesion: 18F-fluorodeoxyglucose/Positron Emission Tomography (18FDG/PET) examination showing increased lymph node or extranodal uptake (higher than liver) and PET and/or computed tomography (Computed Tomography) CT) features are consistent with lymphoma findings; lesions can be measured: nodular lesions > 15mm or extranodal lesions > 10mm (if the only measurable lesion has received radiotherapy in the past, there must be evidence of radiological progress after radiotherapy), and accompanied by increased 18FDG uptake). Except for this, there is no measurable increase in diffuse 18FDG uptake in the liver;
Adequate organ and bone marrow function, no severe hematopoietic dysfunction, cardiac, pulmonary, liver, kidney, thyroid dysfunction and immune deficiency (no blood transfusion, granulocyte colony stimulating factor or other medical support was received within 14 days prior to the use of the research drug): 1) The absolute value of neutrophils (>1.5×10^9/L); 2) platelet count (> 75×10^9/L); 3) Hemoglobin (> 9 g/dL); 4) Upper Limit Normal (ULN) or creatinine clearance rate (>40 mL/min) of serum creatinine (<1.5 times normal value upper limit) (estimated by Cockcroft-Gault formula); 5) Serum total bilirubin < 1.5 times ULN; 6) Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) = 2.5 times ULN; 7) Coagulation function: International Normalized Ratio (INR) = 1.5 times ULN; Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT) = 1.5 times ULN (unless the subject is receiving anticoagulant therapy and PT and APTT are using anticoagulant therapy at screening time). Within the expected range; 8) Thyrotropin (TSH) or free thyroxine (FT4) or free triiodothyronine (FT3) were all within the normal range (+10%);
There was no evidence that subjects had difficulty breathing at rest, and the measured value of pulse oximetry at rest was more than 92%;
Participants must pass a pulmonary function test (PFT) to confirm that forced expiratory volume (FEV1)/forced vital capacity (FVC) in the first second is more than 60%, unless it is a large mediastinal mass caused by lymphoma that cannot meet this standard; carbon monoxide diffusion (DLCO), FEV1 and FVC are all above 50% of the predicted value; all PFT results must be obtained within four weeks before the first administration;
Women of Childbearing Potential (WOBCP) must undergo a serum pregnancy test within seven days before the first medication and the results are negative. WOBCP or men and their WOBCP partners should agree to take effective contraceptive measures from the signing of ICF until six months after the last dose of the research drug is used.

Exclusion criteria

Hemophagocytic syndrome;
Previously treated with immunological checkpoint inhibitors (PD-1, PD-L1, CTLA-4, etc.);
History of severe allergies or allergic reactions to humanized or murine monoclonal antibodies;
Patients with active autoimmune diseases requiring systematic treatment in the past two years (hormone replacement therapy is not considered systematic treatment, such as type I diabetes mellitus, hypothyroidism requiring only thyroxine replacement therapy, adrenocortical dysfunction or pituitary dysfunction requiring only physiological doses of glucocorticoid replacement therapy); Patients with autoimmune diseases who do not require systematic treatment within two years can be enrolled;
Begin the study on subjects requiring systemic glucocorticoid therapy or other immunosuppressive therapy for a given condition within 14 days before treatment [allowing subjects to use local, ocular, intra-articular, intranasal and inhaled glucocorticoid therapy (with very low systemic absorption); and allowing short-term (< 7 days) glucocorticoid prophylaxis (e.g., contrast agent overdose) Sensitivity) or for the treatment of non-autoimmune diseases (e.g. delayed hypersensitivity caused by contact allergens), except for tumor reduction due to large tumor burden (prednisone 30mg, bid × 5 days or equivalent dose of other glucocorticoid therapy);
In the past five years, patients with other malignant tumors have undergone radical treatment, except for basal cell carcinoma of skin, squamous cell carcinoma of skin, carcinoma in situ of breast and carcinoma in situ of cervix;
Begin the study and receive systemic antineoplastic therapy within 28 days before treatment, including chemotherapy, immunotherapy, biotherapy (cancer vaccine, cytokines, or growth factors that control cancer), etc.;
The study began with major surgery within 28 days before treatment or radiotherapy within 90 days before treatment;
Start the study and receive Chinese herbal medicine or Chinese patent medicine treatment within 7 days before treatment;

Patients who are positive for hepatitis B Surface Antigen (HBsAg) or hepatitis C Virus (HCV) antibodies at screening stage must pass further detection of hepatitis B Virus (HBV) DNA titer (no more than 2500 copies/mL or 500 IU/mL) and HCV RNA (no more than the lower limit of the detection method) in the row. In addition to active hepatitis B or hepatitis C infections requiring treatment, group trials can be conducted. Hepatitis B carriers, stable hepatitis B (DNA titer should not be higher than 2500 copies/mL or 500 IU/mL) after drug treatment, and cured hepatitis C patients can be enrolled in the group; 19. Patients with active pulmonary tuberculosis;
Start studying any active infections requiring systemic anti-infective treatment within 14 days of treatment.

People with known history of alcoholism or drug abuse;
Have uncontrollable complications, including but not limited to symptomatic congestive heart failure, uncontrollable hypertension, unstable angina, active peptic ulcer or hemorrhagic diseases;
History of interstitial lung disease or non-infectious pneumonia. Subjects who had previously had non-infectious pneumonia caused by drugs or radiation but had no symptoms were allowed to enter the group;
The QTcF interval is more than 450 msec, unless it is secondary to bundle branch block;
Past psychiatric history; incapacitated or restricted;
According to the researchers' judgment, patients' underlying condition may increase their risk of receiving research drug treatment, or confuse their judgment on toxic reactions;
Other researchers consider it unsuitable for patients to participate in this study.
