DARZALEX® (daratumumab) subcutaneous formulation shows 51 percent reduction in risk of progression to active multiple myeloma for patients with high-risk smouldering multiple myeloma

BEERSE, BELGIUM (8 December 2024) – Janssen-Cilag International NV, a Johnson & Johnson company, today announced data from the Phase 3 AQUILA study showing that DARZALEX® (daratumumab) subcutaneous (SC) formulation significantly delayed progression from high-risk smouldering multiple myeloma (SMM) to active multiple myeloma (MM) and extended overall survival compared to the current standard of care of active monitoring.¹ The data were presented for the first time as an oral presentation at the 2024 American Society of Hematology (ASH) Annual Meeting (Abstract #773), taking place in San Diego, California, United States from 7-10 December, as part of the Press Programme and were selected for the Best of ASH session.1 The data were also simultaneously published in The New England Journal of Medicine.²

“Patients with high-risk smouldering multiple myeloma, which has no approved treatment, have a high probability of progressing to active multiple myeloma – a life-threatening stage of the disease,” said Meletios A. Dimopoulos, M.D., Professor and Chairman of the Department of Clinical Therapeutics at the National and Kapodistrian University of Athens School of Medicine and presenting author.* “Findings from AQUILA highlight the potential of early intervention with daratumumab SC to delay disease progression, extend overall survival and prevent end-organ damage associated with active multiple myeloma.”

In the AQUILA study, 194 patients received daratumumab SC and 196 patients were actively monitored per current standard of care treatment for high-risk SMM.¹ At a median follow-up of 65.2 months (range, 0-76.6), patients who received daratumumab SC showed statistically significant improved progression-free survival (PFS; defined as progression to active MM, as assessed according to the International Myeloma Working Group diagnostic criteria for MM [SLiM-CRAB], or death) vs patients who underwent active monitoring; 63.1 percent in the daratumumab arm vs 40.8 percent in the active monitoring arm remained alive and progression-free at 60 months (Hazard Ratio [HR], 0.49; 95.0 percent Confidence Interval [CI], 0.360.67; p<0.001).¹ Among patients who were retrospectively categorised as having high-risk SMM, per the current Mayo 2018 criteria (20/2/20), median PFS was not reached in the daratumumab arm and was 22.1 months in the active monitoring arm (HR, 0.36; 95.0 percent CI, 0.23-0.58).¹ Overall survival was also extended with daratumumab SC, with 5-year survival rates of 93.0 percent vs 86.9 percent for active monitoring (HR, 0.52; 95.0 percent CI, 0.27-0.98).¹

“Smouldering multiple myeloma represents a critical gap in care, with patients currently limited to treatment-free active monitoring upon diagnosis,” said Edmond Chan, MBChB, M.D. (Res), EMEA Therapeutic Area Lead Hematology, Johnson & Johnson Innovative Medicine. “The AQUILA study offers a compelling case for shifting the treatment paradigm towards early disease interception for high-risk patients, showing treatment with fixed-duration daratumumab SC reduces end-organ damage and disease progression. These results underscore our commitment to addressing unmet needs and changing the way we manage multiple myeloma in its earliest stages.”

Additionally, patients who received daratumumab SC saw a higher overall response rate of 63.4 percent compared to 2.0 percent with active monitoring (p<0.001).¹ Median time to first-line MM treatment was not reached for patients receiving daratumumab SC compared to 50.2 months with active monitoring (HR, 0.46; 95 percent CI, 0.33-0.62; nominal p<0.0001).^1,3

“We are encouraged by the findings from the AQUILA study, which may help to underscore the critical role of early disease intervention and potential to improve outcomes for patients with high-risk smouldering multiple myeloma,” said Jordan Schecter, M.D., Vice President, Disease Area Leader, Multiple Myeloma, Johnson & Johnson Innovative Medicine. “This proactive approach further highlights our goal of evolving the standard of care for patients at every stage of the disease.” ^-490393

Grade 3/4 treatment-emergent adverse events (TEAEs) occurred in 40.4 percent of patients treated with daratumumab SC and 30.1 percent of patients actively monitored.¹ The most common (≥5 percent in either group) Grade 3/4 TEAE was hypertension (5.7 percent vs 4.6 percent, respectively).¹ The frequency of TEAEs leading to discontinuation of daratumumab SC was low (5.7 percent), as was the incidence of fatal TEAEs in both groups (0.5 percent vs 2.0 percent, respectively).¹

Last month, Johnson & Johnson submitted an Extension of Indication application to the European Medicines Agency and a supplemental Biologics License Application to the U.S. Food and Drug Administration for daratumumab SC and DARZALEX FASPRO®, respectively, for the treatment of adult patients with high-risk SMM based on the Phase 3 AQUILA data.⁴

About the AQUILA Study
AQUILA ( NCT03301220 ) is a randomised, multicentre Phase 3 study investigating daratumumab SC vs active monitoring in patients (n=390) with high-risk smouldering multiple myeloma (SMM).5 The primary endpoint is progression-free survival and secondary endpoints include time to progression, overall response rate and overall survival.⁵ Patients in the study were diagnosed with SMM in the last five years and were excluded if they had prior exposure to approved or investigational treatments for SMM or multiple myeloma.⁵

About Smouldering Multiple Myeloma
SMM is an early precursor of active multiple myeloma where abnormal cells can be detected in the bone marrow, but patients are typically asymptomatic.^6,7 People living with SMM tend not to show signs or symptoms typically associated with active myeloma, such as bone pain, bone fractures, kidney problems, or anaemia, however as abnormal plasma cells are present, organ damage may begin and progress asymptomatically.^7,8 Approximately fifteen percent of all cases of newly diagnosed multiple myeloma are classified as SMM, and half of those diagnosed with high-risk SMM will progress to active multiple myeloma within two years.⁹

About Multiple Myeloma
Multiple myeloma is currently an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.^10,11 In multiple myeloma, these malignant plasma cells continue to proliferate, accumulating in the body and crowding out normal blood cells, as well as often causing bone destruction and other complications.¹¹ In the European Union, it is estimated that more than 35,000 people were diagnosed with multiple myeloma in 2022, and more than 22,700 patients died.¹² Whilst some patients with multiple myeloma initially have no symptoms, others can have common signs and symptoms of the disease, which can include bone fracture or pain, low red blood cell counts, fatigue, high calcium levels, infections, or kidney damage.¹³

About Daratumumab and Daratumumab SC
Johnson & Johnson is committed to exploring the potential of daratumumab for patients with multiple myeloma across the spectrum of the disease.

In August 2012 , Janssen Biotech, Inc., a Johnson & Johnson company and Genmab A/S entered a worldwide agreement, which granted Johnson & Johnson an exclusive licence to develop, manufacture and commercialise daratumumab. Since launch, daratumumab has become a foundational therapy in the treatment of multiple myeloma, having been used in the treatment of more than 585,000 patients worldwide.¹⁴ Daratumumab is the only CD38-directed antibody approved to be given subcutaneously to treat patients with multiple myeloma.¹⁵ Daratumumab SC is co-formulated with recombinant human hyaluronidase PH20 (rHuPH20), Halozyme’s ENHANZE® drug delivery technology.¹⁵

CD38 is a surface protein that is present in high numbers on multiple myeloma cells, regardless of the stage of disease.¹⁵ Daratumumab binds to CD38 and inhibits tumour cell growth causing myeloma cell death.¹⁵ Daratumumab may also have an effect on normal cells.¹⁵ Data across ten Phase 3 clinical trials, in both the frontline and relapsed settings, have shown that daratumumab-based regimens resulted in significant improvement in progression-free survival and/or overall survival.^{15,16,17,18,19,20,21,22,23,24}
