injection of DARZALEX (1 800 mg, week 1), 0.5% with the week 2 injection and 1.3% with subsequent injections. Grade 3 and 4 IRRs were observed in 0.8% and 0.1% of patients, respectively.
Signs and symptoms of IRRs may include respiratory symptoms, such as nasal congestion, cough, throat irritation, allergic rhinitis, wheezing, as well as pyrexia, chest pain, pruritus, chills, vomiting, nausea, blurred vision and hypotension. Serious reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, tachycardia and ocular adverse reactions (including choroidal effusion, acute myopia and acute angle-closure glaucoma) (see section 4.4).
Injection site reactions (ISRs)
In clinical studies (N=1 573) with the subcutaneous formulation of DARZALEX, the incidence of injection site reactions of any grade was 10.2%. No grade 3 or 4 ISRs were observed. The most common (>1%) ISRs at the injection site were erythema and rash.
Infections
In patients with multiple myeloma treated with daratumumab as monotherapy, the overall incidence of infections was similar between the group treated with the subcutaneous formulation of DARZALEX (52.9%) and the group treated with intravenous daratumumab (50.0%). Grade 3 or 4 infections also occurred with similar frequency with the subcutaneous formulation of DARZALEX (11.7%) and intravenous daratumumab (14.3%). The majority of infections were manageable and rarely led to treatment discontinuation. Pneumonia was the most commonly reported grade 3 or 4 infection in the studies. In active-controlled studies, treatment discontinuations due to infections occurred in 1-4% of patients. Fatal infections were mainly due to pneumonia and sepsis.
In patients with multiple myeloma who received daratumumab in combination therapy, the following were reported:
Grade 3 or 4 infections:
Studies in relapsed/refractory patients: DVd: 21%, Vd: 19%; DRd: 28%; Rd: 23%; DPd: 28%.
Studies in newly diagnosed patients: D-VMP: 23%, VMP: 15%; DRd: 32%, Rd: 23%; D-VTd: 22%, VTd: 20%.
Grade 5 (fatal) infections:
Studies in relapsed/refractory patients: DVd: 1%, Vd: 2%; DRd: 2%, Rd: 1%; DPd: 2%
Studies in newly diagnosed patients: D-VMP: 1%, VMP: 1%; DRd: 2%, Rd: 2%; D-VTd: 0%, VTd: 0%.
In patients with multiple myeloma who received combination therapy with the DARZALEX subcutaneous formulation, the following infections were reported:
Grade 3 or 4 infections: DPd: 28%, Pd: 23%; D-VRd (transplant-eligible): 35%, VRd (transplant-eligible): 27%; D-VRd (not transplant-eligible): 40%; VRd (not transplant-eligible): 32%
Grade 5 (fatal) infections: DPd: 5%, Pd: 3%; D-VRd (transplant-eligible): 2%, VRd (transplant-eligible): 3%; D-VRd (not transplant-eligible): 8%; VRd (not transplant-eligible): 6%
Legend: D = daratumumab; Vd = bortezomib-dexamethasone; Rd = lenalidomide-dexamethasone; Pd = pomalidomide-dexamethasone; VMP = bortezomib-melphalan-prednisone; VTd = bortezomib-thalidomide-dexamethasone; VRd = bortezomib-lenalidomide-dexamethasone.
In patients with indolent or smouldering multiple myeloma at high risk of developing multiple myeloma who received the DARZALEX subcutaneous formulation as monotherapy, the following infections were reported:
Grade 3 or 4 infections: DARZALEX subcutaneous formulation: 16%
Grade 5 infections: DARZALEX subcutaneous formulation: 1%
In patients with AL amyloidosis who received combination therapy with the DARZALEX subcutaneous formulation, the following infections were reported:
Grade 3 or 4 infections: D-VCd: 17%, VCd: 10%
Grade 5 infections: D-VCd: 1%, VCd: 1%
