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.

Cardiac Safety of the Trastuzumab Biosimilar ABP 980 in Women with HER2-Positive Early Breast Cancer in the Randomized, Double-Blind, Active-Controlled LILAC Study.

Introduction: Although the human epidermal growth factor receptor 2 (HER2) blocker trastuzumab is generally well tolerated, cardiotoxicity can be an important therapeutic limitation.

Objective: In this prespecified analysis, we compared the cardiac safety of the trastuzumab biosimilar ABP 980 (KANJINTI™) and the trastuzumab reference product (RP; Herceptin) in the phase III LILAC study (ClinicalTrials.gov identifier NCT01901146).

Totality of Scientific Evidence in the Development of ABP 980, a Biosimilar to Trastuzumab.

ABP 980 was developed as a biosimilar to trastuzumab, a monoclonal antibody targeting human epidermal growth factor receptor 2 (HER2), that is indicated for the treatment of HER2-positive metastatic breast cancer, early breast cancer (EBC), and metastatic gastric cancer. ABP 980 is approved in the United States, European Union, and Japan for all the indications of trastuzumab, based on the totality of evidence (TOE) gathered by the systematic step-wise accumulation of comparative analytical, preclinical, and clinical (pharmacokinetics [PK], efficacy, safety and immunogenicity) data for ABP 980 and trastuzumab reference product (RP). As a key first step of the ABP 980 biosimilar program, comprehensive analytical characterization of critical quality attributes established that ABP 980 is structurally and functionally similar to trastuzumab RP.

Totality of evidence in the development of ABP 215, an approved bevacizumab biosimilar.

ABP 215 (MVASI™) is the first approved biosimilar to Avastin (bevacizumab). It is approved in the USA and the European Union (EU) for all bevacizumab indications in these jurisdictions except for ovarian cancer in the USA due to orphan drug exclusivity. ABP 215 was shown to be structurally, functionally and clinically (pharmacokinetic, efficacy and safety) similar to the bevacizumab reference product; the pharmacokinetic study was conducted in healthy adult men (n = 202); safety and efficacy were evaluated in patients with advanced nonsquamous non-small-cell lung cancer (n = 642).

Biosimilars: what the oncologist should know.

As originator biologic medicines lose patent protection, some biopharmaceutical companies are focusing on developing similar versions of these costly and complex therapies with a goal of providing more affordable treatment options. Many of these molecules, known as biosimilars, are now approved worldwide and several more are expected to be introduced in the near future. As more biosimilars become available, it is important for clinicians to become familiar with this new category of products and understand how biosimilars are developed, how their development differs from that of originator biologics and how they differ from generics.

Efficacy and safety of flibanserin in postmenopausal women with hypoactive sexual desire disorder: results of the SNOWDROP trial.

Objective: This study aimed to assess the efficacy and safety of flibanserin, a serotonin receptor 1A agonist/serotonin receptor 2A antagonist, in postmenopausal women with hypoactive sexual desire disorder (HSDD).

Methods: Naturally postmenopausal women with HSDD received flibanserin 100 mg once daily at bedtime (n = 468) or placebo (n = 481) for 24 weeks. Co-primary endpoints were changes from baseline to week 24 in the number of satisfying sexual events (SSEs) across 28 days and in the Female Sexual Function Index (FSFI) desire domain score.

Evaluation of the Sexual Desire Relationship Distress Scale (SDRDS) in women with hypoactive sexual desire disorder.

Introduction: The Sexual Desire Relationship Distress Scale (SDRDS) was developed to address the need for a patient-reported outcome (PRO) measure of sexual distress associated with hypoactive sexual desire disorder (HSDD). The SDRDS is a 17-item PRO that includes items related to personal distress and distress related to relationship with partner.

Aim: The aim of this article was to evaluate the psychometric properties of the SDRDS among women with HSDD.

Content validity of the Female Sexual Function Index (FSFI) in pre- and postmenopausal women with hypoactive sexual desire disorder.

Introduction: The Female Sexual Function Index (FSFI) has consistently been shown to have discriminant validity, test-retest reliability, and internal consistency as a measure of female sexual function. However, the content validity (relevance, clarity, comprehensiveness) of the instrument in women with hypoactive sexual desire disorder (HSDD) must also be established.

Aim: The aim of this study were to assess the content validity of the FSFI, specifically the FSFI desire domain, in pre- and postmenopausal women with HSDD.
