Comparative clinical efficacy and safety of biosimilar ABP 959 and eculizumab reference product in patients with paroxysmal nocturnal hemoglobinuria.

ABP 959 is a biosimilar to the eculizumab reference product (RP), which is approved for the treatment of patients with paroxysmal nocturnal hemoglobinuria (PNH). This multicenter, randomized, double-blind, active-controlled, two-period crossover study randomized eculizumab RP-treated patients with PNH to one of two treatment sequences (ABP 959/eculizumab RP or eculizumab RP/ABP 959) to evaluate the clinical similarity of ABP 959 when compared with eculizumab RP. This study evaluated the efficacy of ABP 959 when compared with eculizumab RP based on control of intravascular hemolysis as measured by lactate dehydrogenase (LDH) and by the time-adjusted area under the effect curve of LDH.

A randomized, double-blind, single-dose study (LAVENDER) to assess the safety, tolerability, pharmacokinetics, and immunogenicity of a combined infusion of ABP 980 and pertuzumab in healthy subjects.

Purpose: ABP 980 (KANJINTI) is a biosimilar to reference product HERCEPTIN (trastuzumab RP). The goal of this study was to characterize the safety, tolerability, and immunogenicity of ABP 980 plus pertuzumab (PERJETA) when co-administered in a single infusion bag in healthy subjects.

Methods: This randomized, double-blind, single-dose, 2-arm, parallel-group study (LAVENDER Study) evaluated an intravenous (IV) infusion of ABP 980 (6 mg/kg) plus pertuzumab (420 mg) combined in a single infusion bag relative to an IV infusion of trastuzumab RP (6 mg/kg) plus pertuzumab (420 mg) combined in a single infusion bag given over 60 min.

Is weight-based IV dosing of trastuzumab preferable to SC fixed-dose in some patients? A systematic scoping review.

Trastuzumab, a key treatment for HER2-positive breast cancer, is available in weight-based IV and fixed-dose (600 mg) SC formulations. While the Phase 3 HannaH trial indicated non-inferiority of the SC formulation, there is some concern that the target plasma concentration may not be reached in overweight/obese patients whereas low-body-weight patients may be at risk of toxicity. This scoping review evaluated whether overweight/obese patients are at risk of below-target exposure with fixed-dose SC trastuzumab, whether low-body-weight patients are at risk of increased toxicity, especially cardiotoxicity, and whether IV and SC trastuzumab are equivalent in terms of treatment-emergent adverse events (TEAEs) (e.

Totality of Evidence Supporting the Use of ABP 980, a Trastuzumab Biosimilar: Practical Considerations.

ABP 980 (KANJINTI™, Amgen, Thousand Oaks, CA, USA; Amgen Europe B.V., The Netherlands) is a biosimilar to trastuzumab (Herceptin), a monoclonal antibody that selectively binds human epidermal growth factor receptor-2 (HER2).
