Official Title
A Cross-sectional Study on the Efficacy and Safety of the Combination of Daratumumab+Bortezomib+Dexamethasone Regimen and Dapagliflozin in the Treatment of M-protein Related Cardiac Disease
Brief Summary

It is expected to include 40 patients with M-protein related cardiac disease. Thetreatment medication for enrolled patients must comply with the treatment regimen ofDaratumumab + Bortezomib + Dexamethasone. All patients were given Dapagliflozin 10mg/dayat the beginning of treatment (creatinine clearance rate greater than 20ml/min).

Detailed Description

This study is a multicenter, single arm, observational clinical study.It is expected to
include 40 patients with M-protein related cardiac disease, who will sign informed
consent forms. Collect baseline examination, treatment period (planned 6 cycles), and
follow-up period (survival follow-up) data for patients who meet the inclusion and
exclusion criteria. The treatment medication for enrolled patients must comply with the
treatment regimen of Daratumumab + Bortezomib + Dexamethasone: subcutaneous injection of
1800mg of Daratumumab, d1, 8,15,22 (28 day cycle); (After 2 cycles of improvement in
cardiac indicators, it can be adjusted to intravenous injection of daratumumab);
Bortezomib 1.3 mg/m2 d1, 8, 15, 22; D1, 8, 15, 22; Dexamethasone 20 mg d1, 2, 8, 9, 15,
16, 22, 23. When NTProBNP is greater than 5400ng/ml, bortezomib 1.0mg/m2; When NTProBNP
is greater than 8500ng/ml, bortezomib is 0.7mg/m2. When NTProBNP is greater than
10000ng/ml, bortezomib is temporarily not allowed; NTProBNP greater than 4500ng/ml
dexamethasone starts at 10 mg/dose. All patients were given Dapagliflozin 10mg/day at the
beginning of treatment (creatinine clearance rate greater than 20ml/min).
