Article: Novel protein scaffolds as emerging therapeutic proteins: from discovery to clinical proof-of-concept.
[show abstract] [hide abstract]
ABSTRACT: Recent advances in combinatorial protein engineering have made it possible to develop immunoglobulin (Ig)-based and non-Ig protein scaffolds that can potentially substitute for most whole antibody-associated properties and currently translate into biologicals with drug-like properties. During the past 10 years, the most validated scaffolds have reached the clinical development phase and, recently, one of them [Kalbitor(®) (Dyax)] has made it to the market, making these alternative scaffold proteins viable drug candidates in a post-antibody landscape. Interestingly, several scaffolds include an immune-active component as part of their therapeutic mode of action, which yielded spectacular clinical efficacy in some hematological malignancies. Here, we review the most recent clinical advances and analyze their benefits for patients.Trends in Biotechnology 08/2012; 30(11):575-82. · 9.15 Impact Factor -
Article: IBC's 22nd Annual Antibody Engineering and 9th Annual Antibody Therapeutics International Conferences and the 2011 Annual Meeting of The Antibody Society, December 5-8, 2011, San Diego, CA.

ABSTRACT: The 22nd Annual Antibody Engineering and 9th Annual Antibody Therapeutics international conferences, and the 2011 Annual Meeting of The Antibody Society, organized by IBC Life Sciences with contributions from The Antibody Society and two Scientific Advisory Boards, were held December 5-8, 2011 in San Diego, CA. The meeting drew ~800 participants who attended sessions on a wide variety of topics relevant to antibody research and development. As a preview to the main events, a pre-conference workshop held on December 4, 2011 focused on antibodies as probes of structure. The Antibody Engineering Conference comprised eight sessions: (1) structure and dynamics of antibodies and their membrane receptor targets; (2) model-guided generation of binding sites; (3) novel selection strategies; (4) antibodies in a complex environment: targeting intracellular and misfolded proteins; (5) rational vaccine design; (6) viral retargeting with engineered binding molecules; (7) the biology behind potential blockbuster antibodies and (8) antibodies as signaling modifiers: where did we go right, and can we learn from success? The Antibody Therapeutics session comprised five sessions: (1)Twenty-five years of therapeutic antibodies: lessons learned and future challenges; (2) preclinical and early stage development of antibody therapeutics; (3) next generation anti-angiogenics; (4) updates of clinical stage antibody therapeutics and (5) antibody drug conjugates and bispecific antibodies.mAbs 03/2012; 4(2). -
Article: 6th Annual European Antibody Congress 2010: November 29-December 1, 2010, Geneva, Switzerland.
[show abstract] [hide abstract]
ABSTRACT: The 6th European Antibody Congress (EAC), organized by Terrapinn Ltd., was held in Geneva, Switzerland, which was also the location of the 4th and 5th EAC. As was the case in 2008 and 2009, the EAC was again the largest antibody congress held in Europe, drawing nearly 250 delegates in 2010. Numerous pharmaceutical and biopharmaceutical companies active in the field of therapeutic antibody development were represented, as were start-up and academic organizations and representatives from the US Food and Drug Administration FDA. The global trends in antibody research and development were discussed, including success stories of recent marketing authorizations of golimumab (Simponi®) and canakinumab (Ilaris®) by Johnson & Johnson and Novartis, respectively, updates on antibodies in late clinical development (obinutuzumab/GA101, farletuzumab/MORAb-003 and itolizumab/T1 h, by Glycart/Roche, Morphotek and Biocon, respectively) and success rates for this fast-expanding class of therapeutics (Tufts Center for the Study of Drug Development). Case studies covering clinical progress of girentuximab (Wilex), evaluation of panobacumab (Kenta Biotech), characterization of therapeutic antibody candidates by protein microarrays (Protagen), antibody-drug conjugates (sanofi-aventis, ImmunoGen, Seattle Genetics, Wyeth/Pfizer), radio-immunoconjugates (Bayer Schering Pharma, Université de Nantes) and new scaffolds (Ablynx, AdAlta, Domantis/GlaxoSmithKline, Fresenius, Molecular Partners, Pieris, Scil Proteins, Pfizer, University of Zurich) were presented. Major antibody structural improvements were showcased, including the latest selection engineering of the best isotypes (Abbott, Pfizer, Pierre Fabre), hinge domain (Pierre Fabre), dual antibodies (Abbott), IgG-like bispecific antibodies (Biogen Idec), antibody epitope mapping case studies (Eli Lilly), insights in FcγRII receptor (University of Cambridge), as well as novel tools for antibody fragmentation (Genovis). Improvements of antibody druggability (Abbott, Bayer, Pierre Fabre, Merrimack, Pfizer), enhancing IgG pharmacokinetics (Abbott, Chugai), progress in manufacturing (Genmab, Icosagen Cell Factory, Lonza, Pierre Fabre) and the development of biosimilar antibodies (Biocon, Sandoz, Triskel) were also discussed. Last but not least, identification of monoclonal antibodies (mAbs) against new therapeutic targets (Genentech, Genmab, Imclone/Lilly, Vaccinex) including Notch, cMet, TGFbRII, SEMA4D, novel development in immunotherapy and prophylaxis against influenza (Crucell), anti-tumor activity of immunostimulatory antibodies (MedImmune/Astra Zeneca) and translations to clinical studies including immunogenicity issues (Amgen, Novartis, University of Debrecen) were presented.mAbs 03/2011; 3(2):111-32. -
Article: The next generation of antibody-drug conjugates comes of age.
[show abstract] [hide abstract]
ABSTRACT: Monoclonal antibodies (mAbs) and derivatives are currently the fastest growing class of therapeutic molecules. More than 30 G-type immunoglobulins (IgG) and related agents have been approved over the past 25 years mainly for cancers and inflammatory diseases. In oncology, mAbs are often combined with cytotoxic drugs to enhance their therapeutic efficacy. Alternatively, small anti-neoplastic molecules can be chemically conjugated to mAbs, used both as carriers (increased half-life) and as targeting agents (selectivity). Potential benefits of antibody-drug conjugates (ADCs), strategies, and development challenges are discussed in this review. Several examples of ADCs are presented with emphasis on three major molecules currently in late clinical development as well as next generation thio-mAbs conjugates with improved therapeutic index.Discovery medicine 10/2010; 10(53):329-39. -
Article: Strategies and challenges for the next generation of therapeutic antibodies.
[show abstract] [hide abstract]
ABSTRACT: Antibodies and related products are the fastest growing class of therapeutic agents. By analysing the regulatory approvals of IgG-based biotherapeutic agents in the past 10 years, we can gain insights into the successful strategies used by pharmaceutical companies so far to bring innovative drugs to the market. Many challenges will have to be faced in the next decade to bring more efficient and affordable antibody-based drugs to the clinic. Here, we discuss strategies to select the best therapeutic antigen targets, to optimize the structure of IgG antibodies and to design related or new structures with additional functions.Nature Reviews Immunology 05/2010; 10(5):345-52. · 32.25 Impact Factor
