DARZALEX FASPRO® is the first and only treatment approved by the U.S. FDA for patients with high-risk smoldering multiple myeloma

Phase 3 AQUILA study showed DARZALEX FASPRO® significantly reduced the risk of progression to active multiple myeloma or death by 51 percent compared to active monitoring

Landmark approval supports earlier intervention and disease interception of multiple myeloma for the first time

HORSHAM, Pa., Nov. 6, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced the U.S. Food and Drug Administration (FDA) approved DARZALEX FASPRO® (daratumumab and hyaluronidase-fihj) as a single agent treatment for adult patients with high-risk smoldering multiple myeloma (HR-SMM).1 DARZALEX FASPRO® is the first and only approved treatment for HR-SMM, enabling earlier intervention before the disease progresses to active multiple myeloma.Johnson & Johnson (PRNewsfoto/Johnson & Johnson)

FDA approval is based on findings from the AQUILA study (NCT03301220), which evaluated the efficacy and safety of DARZALEX FASPRO® compared to active monitoring (or "Watch and Wait") in the largest Phase 3 trial in patients with HR-SMM. The AQUILA study demonstrated a significant improvement in the primary endpoint of progression-free survival (PFS), with DARZALEX FASPRO® reducing the risk of disease progression to active multiple myeloma or death by 51 percent compared to active monitoring, according to the International Myeloma Working Group (IMWG) diagnostic criteria for multiple myeloma. Today's milestone follows the May 2025 vote by the U.S. FDA Oncologic Drugs Advisory Committee (ODAC) in favor of the benefit-risk profile of DARZALEX FASPRO® as a single agent treatment for patients with HR-SMM.

Smoldering multiple myeloma (SMM) is an asymptomatic malignancy that is genomically the same as active multiple myeloma and where these abnormal cells can be detected in the bone marrow.2,3,4 In 2025, it is estimated that more than 36,000 people will be diagnosed with multiple myeloma in the U.S., and approximately 15 percent of those are classified as smoldering.5,6 An estimated 50 percent of patients diagnosed with HR-SMM are likely to progress to active disease within two years of diagnosis.6 Currently, the standard of care for HR-SMM is active monitoring to track signs of biochemical progression and/or end-organ damage. Recent evidence suggests that people at high-risk of progressing to active multiple myeloma could benefit from earlier therapeutic intervention.6

"Until now, patients diagnosed with smoldering multiple myeloma only have the option to watch and wait for any active signs of progression to active disease," said Peter Voorhees, M.D., Atrium Health/Levine Cancer Institute, Charlotte, N.C.* "Results from AQUILA demonstrated DARZALEX FASPRO significantly delayed disease progression, underscoring the role of early disease intervention for patients with high-risk smoldering multiple myeloma."

Story Continues

The Phase 3 AQUILA study showed after a median follow-up of 65.2 months, 63.1 percent of patients who received DARZALEX FASPRO® had not progressed to active myeloma at 5 years (60 months) versus 40.7 percent in the active monitoring group (hazard ratio [HR], 0.49; 95 percent confidence interval [CI], 0.36-0.67; P20, and bone marrow plasma cells >20%. DARZALEX FASPRO® is only indicated for patients with high-risk smoldering multiple myeloma and is not indicated for other risk categories.

About Multiple Myeloma

Multiple myeloma is a blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.7 In multiple myeloma, these malignant plasma cells proliferate and replace normal cells in the bone marrow.8 Multiple myeloma is the second most common blood cancer worldwide and remains an incurable disease.9 In 2025, it is estimated that more than 36,000 people will be diagnosed with multiple myeloma in the U.S. and more than 12,000 will die from the disease.5 People with multiple myeloma have a 5-year survival rate of 59.8 percent.10 While some people diagnosed with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels, kidney problems or infections.2,10

About Smoldering Multiple Myeloma

Smoldering multiple myeloma (SMM) is an asymptomatic precursor disease state of multiple myeloma where abnormal cells can be detected in the bone marrow.11 People living with SMM do not show signs or symptoms typically associated with active myeloma, such as bone pain, bone fractures, kidney problems, or anemia. However, as abnormal plasma cells are present, organ damage may begin and progress asymptomatically.4,6 Approximately fifteen percent of all cases are classified as SMM, and half of those diagnosed with high-risk SMM are estimated to progress to active multiple myeloma within two years.6

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

DARZALEX FASPRO® is contraindicated in patients with a history of severe hypersensitivity to daratumumab, hyaluronidase, or any of the components of the formulation.

WARNINGS AND PRECAUTIONS

Hypersensitivity and Other Administration Reactions

Both systemic administration-related reactions, including severe or life-threatening reactions, and local injection-site reactions can occur with DARZALEX FASPRO®. Fatal reactions have been reported with daratumumab-containing products, including DARZALEX FASPRO®.

Systemic Reactions

In a pooled safety population of 1446 patients with multiple myeloma (N=1235) or light chain (AL) amyloidosis (N=193) who received DARZALEX FASPRO® as monotherapy or in combination, 7% of patients experienced a systemic administration-related reaction (Grade 2: 3%, Grade 3: 0.8%, Grade 4: 0.1%). In patients with high-risk smoldering multiple myeloma (N=193), systemic administration-related reactions occurred in 17% of patients in AQUILA (Grade 2: 7%, Grade 3: 1%).

In all patients (N=1639), systemic administration-related reactions occurred in 7% of patients with the first injection, 0.5% with the second injection, and cumulatively 1% with subsequent injections. The median time to onset was 3.2 hours (range: 4 minutes to 3.5 days). Of the 283 systemic administration-related reactions that occurred in 135 patients, 240 (85%) occurred on the day of DARZALEX FASPRO® administration. Delayed systemic administration-related reactions have occurred in 1% of the patients.

Severe reactions included hypoxia, dyspnea, hypertension, tachycardia, and ocular adverse reactions, including choroidal effusion, acute myopia, and acute angle closure glaucoma. Other signs and symptoms of systemic administration-related reactions may include respiratory symptoms, such as bronchospasm, nasal congestion, cough, throat irritation, allergic rhinitis, and wheezing, as well as anaphylactic reaction, pyrexia, chest pain, pruritus, chills, vomiting, nausea, hypotension, and blurred vision.

Pre-medicate patients with histamine-1 receptor antagonist, acetaminophen, and corticosteroids. Monitor patients for systemic administration-related reactions, especially following the first and second injections. For anaphylactic reaction or life-threatening (Grade 4) administration-related reactions, immediately and permanently discontinue DARZALEX FASPRO®. Consider administering corticosteroids and other medications after the administration of DARZALEX FASPRO® depending on dosing regimen and medical history to minimize the risk of delayed (defined as occurring the day after administration) systemic administration-related reactions.

Ocular adverse reactions, including acute myopia and narrowing of the anterior chamber angle due to ciliochoroidal effusions with potential for increased intraocular pressure or glaucoma, have occurred with daratumumab-containing products. If ocular symptoms occur, interrupt DARZALEX FASPRO® and seek immediate ophthalmologic evaluation prior to restarting DARZALEX FASPRO®.

Local Reactions

In this pooled safety population of 1446 patients with multiple myeloma (N=1253) or light chain amyloidosis (N=193), injection-site reactions occurred in 8% of patients, including Grade 2 reactions in 1.1%. The most frequent (>1%) injection-site reaction were injection site erythema and injection site rash. In patients with high-risk smoldering multiple myeloma (N=193), injection-site reactions occurred in 28% of patients, including Grade 2 reactions in 3%. These local reactions occurred a median of 6 minutes (range: 0 minutes to 6.5 days) after starting administration of DARZALEX FASPRO®. Monitor for local reactions and consider symptomatic management.

Infections

DARZALEX FASPRO® can cause serious, life-threatening, or fatal infections. In patients who received DARZALEX FASPRO® in a pooled safety population including patients with smoldering multiple myeloma and light chain (AL) amyloidosis (N=1639), serious infections, including opportunistic infections, occurred in 24% of patients, Grade 3 or 4 infections occurred in 22%, and fatal infections occurred in 2.5%. The most common type of serious infection reported was pneumonia (8.5%).

Monitor patients for signs and symptoms of infection prior to and during treatment with DARZALEX FASPRO® and treat appropriately. Administer prophylactic antimicrobials according to guidelines.

Neutropenia

Daratumumab may increase neutropenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer's prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. Consider withholding DARZALEX FASPRO® until recovery of neutrophils. In lower body weight patients receiving DARZALEX FASPRO®, higher rates of Grade 3-4 neutropenia were observed.

Thrombocytopenia

Daratumumab may increase thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer's prescribing information for background therapies. Consider withholding DARZALEX FASPRO® until recovery of platelets.

Embryo-Fetal Toxicity

Based on the mechanism of action, DARZALEX FASPRO® can cause fetal harm when administered to a pregnant woman. DARZALEX FASPRO® may cause depletion of fetal immune cells and decreased bone density. Advise pregnant women of the potential risk to a fetus. Advise females with reproductive potential to use effective contraception during treatment with DARZALEX FASPRO® and for 3 months after the last dose.

The combination of DARZALEX FASPRO® with lenalidomide, thalidomide, or pomalidomide is contraindicated in pregnant women because lenalidomide, thalidomide, and pomalidomide may cause birth defects and death of the unborn child. Refer to the lenalidomide, thalidomide, or pomalidomide prescribing information on use during pregnancy.

Interference With Serological Testing

Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive indirect antiglobulin test (indirect Coombs test). Daratumumab-mediated positive indirect antiglobulin test may persist for up to 6 months after the last daratumumab administration. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient's serum. The determination of a patient's ABO and Rh blood type are not impacted.

Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received DARZALEX FASPRO®. Type and screen patients prior to starting DARZALEX FASPRO®.

Interference With Determination of Complete Response

Daratumumab is a human immunoglobulin G (IgG) kappa monoclonal antibody that can be detected on both the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and of disease progression in some DARZALEX FASPRO®-treated patients with IgG kappa myeloma protein.

ADVERSE REACTIONS

In multiple myeloma, the most common adverse reaction (≥20%) with DARZALEX FASPRO® monotherapy is upper respiratory tract infection. The most common adverse reactions with combination therapy (≥20% for any combination) include fatigue, nausea, diarrhea, dyspnea, insomnia, headache, rash, pyrexia, cough, muscle spasms, back pain, vomiting, hypertension, musculoskeletal pain, upper respiratory tract infection, peripheral neuropathy, peripheral sensory neuropathy, constipation, pneumonia, edema, peripheral edema, and anemia.

The most common adverse reactions (≥20%) in patients with high-risk smoldering multiple myeloma who received DARZALEX FASPRO® monotherapy are upper respiratory tract infection, musculoskeletal pain, fatigue, diarrhea, rash, sleep disorder, sensory neuropathy, and injection site reactions.

The most common hematology laboratory abnormalities (≥40%) with DARZALEX FASPRO® are decreased leukocytes, decreased lymphocytes, decreased neutrophils, decreased platelets, and decreased hemoglobin.

WARNINGS AND PRECAUTIONS

Infusion-Related Reactions

DARZALEX® can cause severe and/or serious infusion-related reactions including anaphylactic reactions. These reactions can be life threatening, and fatal outcomes have been reported. In clinical trials (monotherapy and combination: N=2066), infusion-related reactions occurred in 37% of patients with the Week 1 (16 mg/kg) infusion, 2% with the Week 2 infusion, and cumulatively 6% with subsequent infusions. Less than 1% of patients had a Grade 3/4 infusion-related reaction at Week 2 or subsequent infusions. The median time to onset was 1.5 hours (range: 0 to 73 hours). Nearly all reactions occurred during infusion or within 4 hours of completing DARZALEX®. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, tachycardia, headache, laryngeal edema, pulmonary edema, and ocular adverse reactions, including choroidal effusion, acute myopia, and acute angle closure glaucoma. Signs and symptoms may include respiratory symptoms, such as nasal congestion, cough, throat irritation, as well as chills, vomiting, and nausea. Less common signs and symptoms were wheezing, allergic rhinitis, pyrexia, chest discomfort, pruritus, hypotension and blurred vision.

When DARZALEX® dosing was interrupted in the setting of ASCT (CASSIOPEIA) for a median of 3.75 months (range: 2.4 to 6.9 months), upon re-initiation of DARZALEX®, the incidence of infusion-related reactions was 11% for the first infusion following ASCT. Infusion-related reactions occurring at re-initiation of DARZALEX® following ASCT were consistent in terms of symptoms and severity (Grade 3 or 4:
