Despite this achievement, most patients with HER2-positive metastatic breast cancer still show progression of their disease, highlighting the need for new therapies. The continuous interest in novel targeted agents led to the development of pertuzumab, the first in a new class of agents, the HER dimerization inhibitors. Pertuzumab is a novel recombinant humanized antibody directed against extracellular domain II of HER2 protein that is required for the heterodimerization of HER2 with other HER receptors, leading to the activation of downstream signalling pathways. Pertuzumab combined with trastuzumab plus docetaxel was approved for the first-line treatment of patients with HER2-positive metastatic breast cancer and is currently used as a standard of care in this indication.

These agents provide numerous benefits compared to traditional small molecule drugs, though their clinical use still requires optimization. The pharmacology of mAbs/ADCs is complex and because ADCs are comprised of multiple components, individual agent characteristics and patient variables can affect their disposition. To further improve the clinical use and rational development of these agents, it is imperative to comprehend the complex mechanisms employed by antibody-based agents in traversing numerous biological barriers and how agent/patient factors affect tumor delivery, toxicities, efficacy, and ultimately, biodistribution.

  • Duchenne Muscular Dystrophy (DMD) Agents
    Therapeutic Class Overview Duchenne muscular dystrophy (DMD) Agents INTRODUCTION • Duchenne muscular dystrophy (DMD) is 1 of 4 conditions known as dystrophinopathies, which are inherited, X-linked myopathic disorders due to a defect in the dystrophin gene that results in the primary pathologic process of muscle fiber degradation. The hallmark symptom is progressive weakness (Darras 2018[a], Darras 2018[b], Muscular Dystrophy Association [MDA] 2019). The other 3 conditions include: Becker muscular dystrophy (BMD), which is a mild form of DMD; an intermediate presentation between BMD and DMD; and DMD-associated dilated cardiomyopathy, which has little or no clinical ○ skeletal or muscle disease (MDA 2019). • DMD symptom onset is in early childhood, usually between the ages of 2 and 3 years old. The proximal muscles are affected first, followed by the distal limb muscles. Generally, the lower external muscles will be affected before the upper. The affected child may have difficulties jumping, walking, and running (MDA 2019). • The prevalence of DMD ranges from 1 to 2 per 10,000 live male births; female-manifesting carriers are rarer, but can present with a range of symptoms that vary in their severities (Birnkrant et al 2018, Darras 2018[a], Emflaza Food and Drug Administration [FDA] Medical Review 2017). • The clinical course and lifespan of patients with DMD is relatively short. Individuals are usually confined to a wheelchair by age 13, and many die in their late teens or twenties from respiratory insufficiency or cardiomyopathy. Although survival until adulthood is more common now, very few patients survive past the 3rd decade (Darras 2018[a]).

  • Letter to FDA on Review of Biogen's Drug
    June 2, 2021 Janet Woodcock, M.D. Acting Commissioner of Food and Drugs Food and Drug Administration 10903 New Hampshire Ave Silver Spring, MD 20993-0002 RE: Food and Drug Administration’s Review of Biogen’s drug Aducanumab for Alzheimer’s disease Dear Acting Commissioner Woodcock: The American Geriatrics Society (AGS), an organization dedicated to improving the health and quality of life of all older adults, is writing to express our concern that the Food and Drug Administration’s (FDA) upcoming review and potential approval of Aducanumab for use in treating patients with mild cognitive impairment (MCI) and Alzheimer’s disease (AD) is premature given the lack of sufficient evidence to support that Aducanumab reduces progression of Alzheimer’s disease and that the potential benefits as a treatment for patients with MCI and AD could outweigh the potential harms. The AGS is a not-for-profit organization comprised of nearly 6,000 geriatrics health professionals who are devoted to improving the health, independence, and quality of life of all older adults. Our members include geriatricians, geriatrics nurse practitioners, social workers, family practitioners, physician assistants, pharmacists, and internists who are pioneers in advanced-illness care for older individuals, with a focus on championing interprofessional teams, eliciting personal care goals, and treating older people as whole persons. We provide leadership to healthcare professionals, policymakers, and the public by implementing and advocating for programs in patient care, research, professional and public education, and public policy. We are familiar with the information that has been released to date. Aducanumab, a human monoclonal antibody developed by Biogen, was assessed in two identical phase III randomized controlled trials, ENGAGE and EMERGE, planned to provide 18-month outcome data in patients with MCI and AD, all with positive amyloid PET scans.

  • Dual Targeting of HER2-Positive Cancer with Trastuzumab Emtansine and Pertuzumab: Critical Role for Neuregulin Blockade in Antitumor Response to Combination Therapy
    Published OnlineFirst October 4, 2013; DOI: 10.1158/1078-0432.CCR-13-0358 Clinical Cancer Cancer Therapy: Clinical Research See related article by Gwin and Spector, p. 278 Dual Targeting of HER2-Positive Cancer with Trastuzumab Emtansine and Pertuzumab: Critical Role for Neuregulin Blockade in Antitumor Response to Combination Therapy Gail D. Lewis Phillips1, Carter T. Fields1, Guangmin Li1, Donald Dowbenko1, Gabriele Schaefer1, Kathy Miller5, Fabrice Andre6, Howard A. Burris III8, Kathy S. Albain9, Nadia Harbeck10, Veronique Dieras7, Diana Crivellari11, Liang Fang2, Ellie Guardino3, Steven R. Olsen3, Lisa M. Crocker4, and Mark X. Sliwkowski1 Abstract Purpose: Targeting HER2 with multiple HER2-directed therapies represents a promising area of treatment for HER2-positive cancers. We investigated combining the HER2-directed antibody–drug con- jugate trastuzumab emtansine (T-DM1) with the HER2 dimerization inhibitor pertuzumab (Perjeta). Experimental Design: Drug combination studies with T-DM1 and pertuzumab were performed on cultured tumor cells and in mouse xenograft models of HER2-amplified cancer. In patients with HER2- positive locally advanced or metastatic breast cancer (mBC), T-DM1 was dose-escalated with a fixed standard pertuzumab dose in a 3þ3 phase Ib/II study design. Results: Treatment of HER2-overexpressing tumor cells in vitro with T-DM1 plus pertuzumab resulted in synergistic inhibition of cell proliferation and induction of apoptotic cell death. The presence of the HER3 ligand, heregulin (NRG-1b), reduced the cytotoxic activity of T-DM1 in a subset of breast cancer lines; this effect was reversed by the addition of pertuzumab. Results from mouse xenograft models showed enhanced antitumor efficacy with T-DM1 and pertuzumab resulting from the unique antitumor activities of each agent.
