Clinical Trial Summary

To assess whether continued treatment to achieve negative Minimal Residual Disease and Imaging (MRDI(-)) improves therapeutic outcomes in patients with newly diagnosed Multiple Myeloma. The primary endpoints are progression-free survival (PFS) and overall survival (OS). The safety evaluation includes the evaluation of adverse events, which are classified according to the Common Criteria for Terminology for Adverse Events of the National Cancer Institute, version 5.0.


Description:

Material and methods - Criteria for Enrollment Patients younger than 76 years, diagnosed with myeloma since July 1, 2014 until May 31, 2019, without a contraindication for bone marrow auto-transplantation are included in the study. Fragile patients with severe senile dementia, with another non-treatable neoplasm, or with significant comorbidity in whom the therapeutic objective was only palliative are not included in the study. The allocation to each treatment group was carried out according to the patient's preferences and his/her responsible physician, giving the patient his/her consent for treatment in all cases. In addition to other information, before patients gave their consent, patients included in the continued treatment group were clarified that it was a non-standard treatment, giving them the choice between the most common option of fixed treatment or continuous treatment up to Minimal Residual Disease and Image negative (MRDI(-)). Material and methods - Study Design and Treatment This is a study of the patients treated in real life hematology. It is a cohort study to compare continuous treatment versus fixed-duration therapy. The study is conducted in a single hospital, including patients diagnosed from July 1, 2014 to May 31, 2019. The autotransplant is considered as a therapeutic line more, and all patients who did not receive the transplant were analyzed as if they had received it. The patients always receive some of the authorized treatments for their therapeutic line, according to the preferences of the responsible hematologist and the patient. After the induction phase, all the patients undergo stem-cell mobilization with granulocyte colony-stimulating factor. The patients of the fixed treatment group (control group) receive up to six cycles of the consolidation treatment after transplantation if complete remission has not been achieved. In the patients of the MRDI-driven group, patients continue treatment after transplantation to achieve complete remission with negative MRD and negative image, changing therapeutic line if not achieved with the prescribed treatment. In this group of the patients the treatment is stopped only when this degree of deep response is achieved, in whatever the treatment phase was. Assessments The treatment response and disease progression are assessed according to the International Uniform Response Criteria for Multiple Myeloma, except that to consider the negative Minimal Residual Disease, a sensitivity level of 10-6 is required. In addition, it is considered negative image only if a Positron Emission Tomography/Computed Tomography (PET/CT) body and spinal and pelvic Nuclear Magnetic Resonance (NMR), are both negative. The work team defined an additional category of relapse: "relapse from MRDI(-)", which includes any of the relapse criteria of negative Minimal Residual Disease, and/or positive image. To evaluate the Positron Emission Tomography/Computed Tomography (PET/CT) the criteria of Elena Zamagni are used. In Nuclear Magnetic Resonance studies, all lesions with a size equal to or greater than 5 mm are considered positive if they are hypointense signal in T1, hyperintense in Fat Suppression (FS) T2 signal, and in the studies of diffusion hyperintense signal in b1000 with apparent diffusion coefficient (ADC) between 0.4 and 1. In perfusion studies, type 4-curve lesions are considered positive. The adverse events are assessed according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 of the National Cancer Institute. It is considered as an Adverse Event (AE) any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure. Among all the patients, bone marrow samples are obtained at diagnostic for cytogenetic evaluation. Among the patients of the MRDI-driven group who are a complete response, bone marrow samples are obtained for minimal residual disease evaluation by means of seven-color flow cytometry (which has a sensitivity level of 10-6, indicating that it can detect 1 malignant plasma cell within 1,000,000 bone marrow cells). If the patient achieve a Complete Remission (CR) according to the International Uniform Response Criteria for Multiple Myeloma, Minimal Residual Disease (MRD) and imaging studies are performed before transplantation, after transplantation, and after every six cycles of treatment in cases with CR where previous MRD or imaging studies are positive. In the control group, the MRD and imaging only occasionally is it evaluated. In all patients who achieve a negative MRD and negative image, MRD and imaging tests are performed at 6 months and annually. The response obtained, progression-free survival, overall survival, and the incidence of adverse effects are valued. Statistical Analysis Progression-free survival is defined as the time from start of treatment until either the first documentation of disease progression or death owing to myeloma or not. Overall survival is defined as the time from start of treatment until death from any cause. Duration of PFS and OS is estimated by means of the test of the long rank Kaplan-Meier method with Cox analysis. Analyses are performed with the use of IBM SPSS Statistics software, version 23.0; the data cutoff date is June 30, 2024.

Intervention

Other:
Continued treatment adapted to the response
Instead of receiving a pre-specified number of treatment cycles, regardless of the result obtained, in the MRDI-driven treatment group patients continue receiving treatment until reaching a complete remission with negative MRD and Image, changing the therapeutic line if it is not obtained with the line current therapy. In this group of the patients the treatment was stopped only when this degree of deep response was achieved.
