Milan, Italy – New research presented at the 2025 European Hematology Association (EHA) Congress reveals that early intervention with daratumumab (Darzalex) significantly benefits multiple myeloma patients experiencing minimal residual disease (MRD) relapse. The PREDATOR-MRD trial (NCT03697655) demonstrates that daratumumab not only prolongs the time to clinical progression but also helps restore MRD negativity in a notable proportion of patients.
Key Findings From the PREDATOR-MRD Trial
The PREDATOR-MRD trial, a significant study in the field of hematological oncology, provides compelling evidence for the early use of daratumumab. Researchers found that the median event-free survival (EFS) was not reached in the daratumumab treatment arm, compared to 9.5 months in the observation arm (HR, 0.20; 95% CI, 0.05-0.76; P = .0097). This indicates a substantial delay in disease progression for those receiving daratumumab.
Notably, 75% of patients in the daratumumab arm re-achieved MRD negativity. This is a critical outcome, as MRD negativity is strongly associated with better long-term outcomes in multiple myeloma.
“MRD monitoring every 4 months allows detection of MRD relapse before any biochemical progression in 75% of patients,” Said Dr. Krzysztof Jamroziak, From The Department Of Hematology, Institute of Hematology and Transfusion Medicine, Warsaw, Poland.
Trial Design and Patient Demographics
The PREDATOR-MRD trial enrolled adults with multiple myeloma who had completed one or two prior lines of therapy and achieved a complete response (CR) with MRD negativity. Following MRD reappearance,patients were randomized to receive daratumumab or undergo observation.
Key patient characteristics included:
- Predominantly female (61.1%)
- Median age of 59 years (range, 45-70)
- Varied International Staging System (ISS) scores: I (35.2%),II (20.4%), III (22.2%)
Adverse Events and Quality of Life
In the daratumumab treatment arm, no patients experienced grade 3 or higher adverse effects. The most common non-hematologic AEs included upper respiratory tract infection (50.0% vs 0.0% in the observation arm) and musculoskeletal pain (41.7% vs 8.3%).
Importantly, daratumumab did not significantly impact the Global Health Score (P = .59),suggesting that the treatment did not negatively affect patients’ overall quality of life.
Implications for Multiple Myeloma Treatment
The PREDATOR-MRD trial’s findings suggest that early intervention with daratumumab upon MRD relapse can significantly alter the course of multiple myeloma. By prolonging event-free survival and restoring MRD negativity, this approach offers a promising strategy for improving patient outcomes.
daratumumab and The Future of Myeloma Treatment
As research continues and new data emerges, Daratumumab may play an increasingly important role in the management of multiple myeloma. Combination therapies and personalized approaches could further enhance its effectiveness, leading to better outcomes for patients worldwide. The PREDATOR-MRD trial serves as a foundation for future studies and clinical practice.

Understanding Multiple Myeloma and MRD
Multiple myeloma is a cancer that forms in plasma cells, a type of white blood cell responsible for producing antibodies.These cancerous plasma cells accumulate in the bone marrow and crowd out healthy blood cells, leading to various complications.
MRD refers to the presence of a small number of cancer cells that remain in the body after treatment. These cells can eventually lead to relapse if not addressed.Highly sensitive MRD testing can detect as few as one myeloma cell among a million normal cells.
Monitoring MRD is increasingly important to ensure successful long-term management of multiple myeloma. According to recent studies, achieving sustained MRD negativity after treatment is associated with significantly longer progression-free survival and overall survival.

Early Daratumumab for myeloma Relapse: A Game Changer in MRD Management
Managing myeloma after minimal residual disease (MRD) relapse is a critical aspect of patient care. Recent advancements, especially the use of daratumumab, have reshaped treatment strategies. Early intervention with daratumumab in patients experiencing MRD relapse has demonstrated notable benefits in delaying disease progression and improving patient outcomes. This article delves into the implications of early daratumumab use, exploring its efficacy, benefits, and practical considerations.
understanding Myeloma, MRD, and Relapse
Multiple myeloma is a cancer of plasma cells, which are found in the bone marrow. Disease management often includes induction therapy, followed by consolidation and maintenance strategies. The concept of minimal residual disease (MRD) refers to the small number of myeloma cells that may persist after treatment, even when no detectable disease is found by standard methods. relapse occurs when these MRD-positive cells begin to proliferate, leading to overt disease progression.
The importance of MRD Testing
MRD testing plays a pivotal role in assessing treatment response and predicting relapse. Advanced techniques, such as next-generation sequencing and flow cytometry, offer highly sensitive methods to detect minimal disease. Early detection of MRD relapse allows for timely intervention. This proactive approach is increasingly recognized as crucial to extending progression-free survival. MRD-guided therapy is a growing trend in myeloma treatment.
The Impact of relapse on Myeloma Patients
Myeloma relapse can significantly impact a patient’s quality of life. The symptoms, including bone pain, fatigue, and increased susceptibility to infections, can be debilitating. Additionally, each subsequent relapse often leads to increased treatment complexity and decreased response rates. Therefore, preventing or delaying relapse is a primary goal in myeloma treatment.
