Of the 291 patients who received DARZALEX FASPRO as monotherapy for relapsed and refractory multiple myeloma, 37% were 65 to <75 years of age, and 19% were 75 years of age or older. No overall differences in effectiveness of DARZALEX FASPRO have been observed between patients ≥65 years of age and younger patients .Adverse reactions that occurred at a higher frequency (≥5% difference) in patients ≥65 years of age included upper respiratory tract infection, urinary tract infection, dizziness, cough, dyspnea, diarrhea, nausea, fatigue, and peripheral edema. Serious adverse reactions that occurred at a higher frequency (≥2% difference) in patients ≥65 years of age included pneumonia. 

Of the 214 patients who received DARZALEX FASPRO as combination therapy with pomalidomide and dexamethasone or DARZALEX FASPRO as combination therapy with lenalidomide and low-dose dexamethasone for relapsed and refractory multiple myeloma, 43% were 65 to <75 years of age, and 18% were 75 years of age or older. No overall differences in effectiveness were observed between patients ≥65 years (n=131) and <65 years (n=85). Adverse reactions occurring at a higher frequency (≥5% difference) in patients ≥65 years of age included fatigue, pyrexia, peripheral edema, urinary tract infection, diarrhea, constipation, vomiting, dyspnea, cough, and hyperglycemia. Serious adverse reactions occurring at a higher frequency (≥2% difference) in patients ≥65 years of age included neutropenia, thrombocytopenia, diarrhea, anemia, COVID-19, ischemic colitis, deep vein thrombosis, general physical health deterioration, pulmonary embolism, and urinary tract infection.

Of the 355 patients who were newly diagnosed with multiple myeloma and eligible for ASCT who received DARZALEX FASPRO as combination therapy with bortezomib, lenalidomide and dexamethasone during induction and consolidation in the clinical trial, 74% were <65 years of age, and 26% were 65 to 70 years of age. The clinical trial did not enroll patients older than 70 years of age [see Clinical Studies (14.1)] . No overall differences in effectiveness of DARZALEX FASPRO in combination with bortezomib, lenalidomide and dexamethasone were observed between patients <65 years of age compared to patients 65 to 70 years of age. Adverse reactions that occurred at a higher frequency (≥5% difference) in patients 65 to 70 years of age included constipation, hemorrhoids, nausea, injection site erythema, bronchitis, nasopharyngitis, back pain, myalgia, pain in extremity, dysgeusia, peripheral motor neuropathy, and insomnia. Serious adverse reactions that occurred at a higher frequency (≥2% difference) in patients 65 to 70 years of age included febrile bone marrow aplasia, atrial fibrillation, pyrexia, and orthostatic hypotension. 

Of the 193 patients who received DARZALEX FASPRO as part of a combination therapy for light chain (AL) amyloidosis, 35% were 65 to <75 years of age, and 10% were 75 years of age or older. Clinical studies of DARZALEX FASPRO as part of a combination therapy for patients with light chain (AL) amyloidosis did not include sufficient numbers of patients aged 65 and older to determine whether effectiveness differs from that of younger patients. Adverse reactions that occurred at a higher frequency in patients ≥65 years of age were peripheral edema, asthenia, pneumonia and hypotension.

No clinically meaningful differences in the pharmacokinetics of daratumumab were observed in geriatric patients compared to younger adult patients [see Clinical Pharmacology (12.3)] .
