About

A single-center, open, single-arm clinical study of the efficacy and safety of a novel targeted agent in combination with R-ICE in the treatment of relapsed and refractory diffuse Large B-cell lymphoma.

Full description

Refractory recurrence of patients with diffuse large B cell lymphoma inclusion/exclusion standard subjects in a signed written informed consent, according to the results of genotyping, divided the patients into MCD, TP53, BN2, EZB, ST2, NOS, N1, a total of 7 kinds of types. New targeted drugs were added based on typing results: Zanubrutinib for MCD and BN2, Decitabine for TP53, Chidamide for EZB, Tofacitinib for ST2, and Pomalidomide for N1 and NOS. After 3 courses of treatment, PET-CT was used to evaluate the efficacy. Patients with CR/PR, aged ≤65 years, qualified and willing for transplantation, were treated with autologous hematopoietic stem cell transplantation (ASCT); Patients who did not meet the above requirements or failed to collect autologous hematopoietic stem cells were placed on new targeted drug maintenance therapy for up to 12 months; If patients were evaluated as SD and PD after 3 cycles, they were treated with other regiments. New targeted drugs combined with R-ICE and ASCT were evaluated every 3 months in the first year and every 6 months in the second and third years after treatment.

Inclusion criteria

DLBCL was confirmed by histology according to world Health Organization (WHO) disease classification (excluding primary central lymphoma and HIV-associated lymphoma);
There are evaluable lesions detected by PET/CT;
Life expectancy of more than 3 months;
Prior treatment with sufficient first-line anti-lymphoma therapy, no remission within 90 days of the last administration, or disease progression after sufficient first-line anti-lymphoma therapy, and no current anti-lymphoma therapy (≥2 weeks since the last anti-lymphoma therapy). Patients were allowed to receive hormone drugs or rituximab at least 1 week after enrollment for symptom control reasons;
18≤ age ≤75 years old, male and female;
ECOG 0-2 points;
No serious organic lesions in the main organs, meeting the requirements of the following laboratory examination indicators (conducted within 7 days before treatment) :

① Absolute value of neutrophil count ≥1500/mm3; Platelet count ≥75,000/mm3

② Total bilirubin ≤2× upper limit of normal value (ULN)

③ Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (serum glutamate pyruvate aminotransferase [SGPT]) ≤3× upper limit of normal value (ULN)

④ the creatinine clearance rate was ≥60ml/min

⑤ No cardiac dysfunction
If the subject is of reproductive age and requires effective contraception, he/she agrees to comply with all contraceptive requirements: 1) there are fertile women have to decide, at the same time take two reliable contraceptive methods (a kind of high efficient contraceptives - tubal ligation, intrauterine contraceptive device, hormone (birth control pills, needle, patch, vaginal ring or implants) or partner vasectomy, another effective birth control method -- men or synthetic rubber condom, diaphragm or cervical cap). 2) Unless hysterectomy, effective contraception is required even if there is a history of infertility;
Fertile men must always use rubber or synthetic condoms when having sexual contact with fertile women during the use of this product and within 28 days of discontinuation of this product, even if they have successfully vasectomy; The subjects knew the characteristics of the disease, voluntarily joined the study, received treatment and follow-up, and the informed consent was signed by the subjects themselves or their guardians and impartial witnesses.

Exclusion criteria

Subjects with a history of deep vein thrombosis (DVT) or pulmonary embolism (PE) within the past 12 months;
Bone marrow failure, defined as ANC<1500/mm3 or platelet <75,000/mm3, unless hematologic changes are thought to be associated with lymphomas infiltrating the bone marrow;

Lymphoma with central nervous system (CNS) involvement;
Those who are known to be allergic to the test drug ingredients;
Those who have received grade II or above surgery within three weeks before treatment;
Patients who have received organ transplants;
Has been diagnosed with or is being treated for malignancy other than lymphoma, except for:

① They have received therapeutic treatment and have not had known active disease malignancy for ≥5 years prior to enrollment;

② Basal cell carcinoma of the skin (except melanoma) without signs of disease after adequate treatment;
