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.

Attention: Dhushy Thambipillai Regulatory Project Management 1 DNA Way, Bldg 45-1 South San Francisco, CA 94080 RE: Emergency Use Authorization 099 Dear Ms. Thambipillai: This letter is in response to Genentech, Inc.’s (Genentech) request that the Food and Drug Administration (FDA) issue an Emergency Use Authorization (EUA) for the emergency use of Actemra1 (tocilizumab) for the treatment of coronavirus disease 2019 (COVID-19) in certain hospitalized patients, as described in the Scope of Authorization (Section II) of this letter, pursuant to Section 564 of the Federal Food, Drug, and Cosmetic Act (the Act) (21 U.S.C. §360bbb-3). On February 4, 2020, pursuant to Section 564(b)(1)(C) of the Act, the Secretary of the Department of Health and Human Services (HHS) determined that there is a public health emergency that has a significant potential to affect national security or the health and security of United States citizens living abroad, and that involves the virus that causes coronavirus disease 2019 (COVID-19).2 On the basis of such determination, the Secretary of HHS on March 27, 2020, declared that circumstances exist justifying the authorization of emergency use of drugs and biological products during the COVID-19 pandemic, pursuant to Section 564 of the Act (21 3 U.S.C. 360bbb-3), subject to terms of any authorization issued under that section. Actemra is a recombinant humanized monoclonal antibody that selectively binds to both soluble and membrane-bound human IL-6 receptors (sIL-6R and mIL-6R) and subsequently inhibits IL- 6-mediated signaling through these receptors.

Kevin Park1 Abstract | Immunomodulatory biologics, which render their therapeutic effects by modulating or harnessing immune responses, have proven their therapeutic utility in several complex conditions including cancer and autoimmune diseases. However, unwanted adverse reactions — including serious infections, malignancy, cytokine release syndrome, anaphylaxis and hypersensitivity as well as immunogenicity — pose a challenge to the development of new (and safer) immunomodulatory biologics. In this article, we assess the safety issues associated with immunomodulatory biologics and discuss the current approaches for predicting and mitigating adverse reactions associated with their use. We also outline how these approaches can inform the development of safer immunomodulatory biologics. Immunomodulatory Biologics currently represent more than 30% of licensed The high specificity of the interactions of immu- biologics pharmaceutical products and have expanded the thera- nomodulatory biologics with their relevant immune Biotechnology-derived peutic options available

  • Astra Makes Quiet Progress with Respiratory Pipeline
    June 18, 2014 Astra makes quiet progress with respiratory pipeline Jonathan Gardner In defending AstraZeneca against acquisition by Pfizer its executives pointed to oncology candidates such as the checkpoint inhibitor Medi4736 and lung cancer project AZD9291 as assets not fully valued by the American pursuer. Less well appreciated is Astra's portfolio of clinical-stage respiratory programmes, one of which appears to be the only project of its class to be tested in the clinic. Given Astra's relative position in each therapy area, one might think that respiratory disease would draw more attention, even though oncology remains the hottest area of drug development. A focus on novel classes and severe disease – demonstrated by a licensing deal last week for an inhalable interferon for asthma – could allow Astra to expand even as growth in respiratory therapies flattens through the rest of the decade. Ordinary and unusual Astra executives themselves have made less of the respiratory disease pipeline, forecasting sales that are in line with consensus figures even as they pumped up the group’s collective R&D (Don’t blame Soriot, he’s just doing his job, May 7, 2014). In some respects, it is somewhat ordinary: the phase III pipeline features some candidates in well-established classes like long-acting beta-2 agonists (LABAs) in the form of assets brought on board with the acquisition of Pearl Therapeutics (Astra’s Soriot finds hidden value in private assets, June 10, 2013). James Ward-Lilley, the UK group’s vice-president of respiratory, inflammation and autoimmune disease, acknowledged that the respiratory group had not received the attention of the investor community in part because the potential payoff of a clinical gamble is not valued as highly.
