Active clinical trials for "Neoplasms, Plasma Cell"

Aim of this study is to evaluate Daratumumab effect on MRD-positive patients with Multiple Myeloma (MM) who achieved >VGPR after any therapy (ASCT, VMP, Rev-Dex). Daratumumab 16 mg/kg administered at weekly intervals for 8 weeks, then every 2 weeks for an additional 16 weeks, will be given to 50 MM patients who achieved a >VGPR defined by monoclonal component disappearance in serum or urine, immunofixation positive/negative and MRD-positivity (by NGF). Free light chain (FLC) and CT/PET will be evaluated at time 0. NGF will be done on marrow aspirate at time 0, at 2 months and every 6 months for 2 years. If patients will be still MRD positive after 6 months of therapy , treatment will be continued up to 2 years. If MRD negative by NGF, the patients can stop the treatment.

The clinical trial was conducted in a cohort of young, high-risk myeloma patients who were designed to receive a combination of high-dose chemotherapy with allogeneic or autologous hematopoietic stem cell transplantation. The objective was to assess the progression free survival (PFS), overall survival (OS),and overall response rate (ORR) of the overall treatment.

Multiple myeloma (MM) is a common malignant hematology disease. The development of proteasome inhibitors (PIs) and immunomodulatory drugs (IMiDs) significantly improved the survival of MM patients. IMiDs have multiple effects in MM therapy. Except for direct cytotoxicity, IMiDs also play a variety of immune regulatory roles. Lenalidomide, a kind of IMiDs, was usually used in the therapy of relapsed/refractory MM. The efficacy and safety of RDD (lenalidomide, pegylated liposomal doxorubicin, dexamethasone) in newly diagnosed patients with MM still needs to be further validated.

It's a single arm, open label prospective study, in which the safety and efficacy of B Cell Maturation Antigen（BMCA）-targeted CAR-T thearpy are evaluated in refractory/relapsed multiple myeloma patients.

The purpose of this study is to evaluate the effects of daratumumab monotherapy on bone disease in patients with relapsed/refractory MM who have received at least 2 prior lines of therapy, including lenalidomide and a PI.

This clinical study is an exploratory study, mainly to study the safety and efficacy of BCMA nano-antibody CAR-T in the treatment of MM. In this study, a 3 + 3 dose gradient climbing design was used. Three dosage groups, 5 x 106 / kg, 7.5 x 106 / kg and 1.5 x 107 / kg, were divided into three groups. Patients were enrolled in the sequence from low to high doses. When each dose group was completed, the next dose group could be enrolled if there was no more than 3-level toxicity or unpredictable severe toxicity. If the dose group had more than 3-level toxicity or unpredictable severe toxicity, two patients were enrolled to observe if there was any toxicity. Sexual occurrence, if two patients in each group developed grade 3 or more toxicity or unpredictable severe toxicity, the dose group was the dose-limiting group, and the dose group in front of the group was the maximum tolerated dose, at which the initial efficacy was observed. Nine patients were enrolled in the hill climbing test, and six patients were enrolled in the follow-up preliminary efficacy study, with an estimated 15 enrolled.

In patients with multiple myeloma with recurrent or refractory BCMA, CAR-T cell infusion was performed after screening, blood collection and pretreatment. Starting dose for 5 x 10^5 / kg, 1 x 10^6 doses sequentially. If dose-limiting toxicity is not observed in 3 patients in a dose group, the next dose group test can be performed; If more than 2/3 of patients (2 cases, included) in a dose group had DLT, dose-escalation was not performed. If 1 case of DLT (1/3) appears in the first 3 patients of a dose group, 3 patients need to be added to the dose group (at this time, there are 6 patients in the group).

A single arm, open-label pilot study is designed to determine the safety, efficacy and cytokinetics of CAR-BCMA T cells in patients with BCMA-positive refractory or relapsed multiple myeloma.

This is a phase I, interventional, single arm, open label, treatment study to evaluate the safety and tolerability of BCMA-CS1 cCAR in patients with relapsed and/or refractory multiple myeloma.

This study is aimed to evaluate the safety, feasibility and efficacy of CAR-T cell therapy in the treatment of relapsed or refractory multiple myeloma
