Patent number: 8192746Abstract: The present invention provides a multivalent immunogenic composition having 15 distinct polysaccharide-protein conjugates. Each conjugate consists of a capsular polysaccharide prepared from a different serotype of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 22F, 23F or 33F) conjugated to a carrier protein, preferably CRM197. The immunogenic composition, preferably formulated as a vaccine on an aluminum -based adjuvant, provides broad coverage against pneumococcal disease, particularly in infants and young children.Type: GrantFiled: February 3, 2011Date of Patent: June 5, 2012Assignee: Merck Sharp & Dohme Corp.Inventors: Michael J.

Patent number: 7811577Abstract: Methods of covalently-stabilizing alpha-helical, chimeric peptides constrained within a homotrimeric or heterotrimeric coiled-coil structure are disclosed. The coiled-coil structures made by the methods disclosed within this specification mimic all or a portion of the internal, trimeric coiled-coil motif contained within the fusogenic conformation of an enveloped virus membrane-fusion protein, particularly the internal coiled-coil domain of the HIV gp41 ectodomain. The HIV-derived, chimeric peptides disclosed comprise a non-HIV, soluble, trimeric form of a coiled-coil fused in helical phase to all or a portion of the N-helix of HIV gp41 and are covalently-stabilized in a homotrimeric or heterotrimeric coiled-coil structure through the formation of disulfide or chemoselective bonds between said peptides.Type: GrantFiled: May 27, 2005Date of Patent: October 12, 2010Assignees: Merck Sharp & Dohme Corp., Istituto Di Ricerche Di Biologia Molecolare P. Angeletti S.p.A.Inventors: Elisabetta Bianchi, Antonello Pessi, Romas Geleziunas, David Bramhill

Patent number: 7744887Abstract: Human scFvs are disclosed which interact with a conformational epitope along the pre-hairpin, N-helix coiled coil structure within the heptad repeat 1 (HR1) region of gp41 of HIV. These antibodies, as well as IgG conversions, are shown to neutralize diverse HIV isolates. Isolated nucleic acid molecules are also disclosed which encode relevant portions of these antibodies, as well as the purified forms of the expressed antibodies or relevant antibody fragments, such as VH and VL chains. The antibody compositions disclosed within this specification may provide for a therapeutic treatment against HIV infection by reducing viral load levels within an infected individual, thus prolonging the asymptomatic phase of HIV infection. These antibodies will also be useful in assays to identify HIV antiviral compounds as well as allowing for the identification of candidate HIV vaccines, such as HIV peptide vaccines.Type: GrantFiled: May 31, 2005Date of Patent: June 29, 2010Assignees: Merck & Co., Inc., Whitehead Insitute of Biomedical Research, MedImmune Limited, Istitute di Ricerche di Biologia Molecolare P. Angeletti S.p.A.Inventors: John W. Shiver, Michael D. Miller, Romas Geleziunas, Daria J. Hazuda, Peter S. Kim, Debra M. Eckert, Michael J. Root, Simon N. Lennard, Elisabetta Bianchi

Patent number: 7456009Abstract: The invention relates to viral formulations and related pharmaceutical products for use in gene therapy and/or vaccine applications. Especially preferred viral formulations disclosed herein are liquid adenovirus formulations, which show improved stability when stored in about the 2-8° C. range while also being compatible with parenteral administration. These formulations comprise a buffer, a sugar, a salt, a divalent cation, a non-ionic detergent, as well as a free radical scavenger and/or a chelating agent to inhibit free radical oxidation.Type: GrantFiled: March 3, 2005Date of Patent: November 25, 2008Assignee: Merck & Co., Inc.Inventors: Robert K. Evans, David B. Volkin, Lynne A. Isopi

Patent number: 7344873Abstract: A simple yet effective method of increasing production of a thermo-stable virus, such as adenovirus and picornavirus, is presented. The method entails a temperature shift strategy whereby the culture of host cells are shifted to a sub-optimal temperature for a period of time prior to virus infection or cells are grown at a sub-optimal level for the entire cell expansion process including one or more than one passages of cell growth from cryopreserved cells, followed by a shift back to a more optimal temperature at or near the time of virus infection of the respective host cells. Adaptation of such a temperature shift strategy present a simple yet effective method to substantially increase recoverable virus within a respective host cell/virus production scheme without the need to further manipulate other culture and/or media conditions within an established host cell/virus production scheme.Type: GrantFiled: March 27, 2003Date of Patent: March 18, 2008Assignee: Merck & Co., Inc.Inventors: Liangzhi Xie, Charles F. Goochee

Patent number: 7316898Abstract: The invention discloses a simple, accurate and reproducible method of determining viral particle concentration, especially for any serotype of adenovirus. More specifically, an accurate absorptivity/extinction coefficient in units of viral particles per milliliter per absorbance unit per centimeter (vp/mL-AU-cm) for a sample virus, such as adenovirus, at 260 nanometers (nm) is disclosed, as well as an ultraviolet (UV) absorbance method to determine virus particle concentrations based on this established absorptivity/extinction coefficient and absorbances at 260 nm for purified virus preparations, such as adenovirus preparations.Type: GrantFiled: February 14, 2003Date of Patent: January 8, 2008Assignee: Merck & Co., Inc.Inventor: Joyce A. Sweeney

Patent number: 7193070Abstract: Disclosed herein are isolated nucleic acid molecules encoding a humanized version of a calcitonin gene-related peptide (CGRP) receptor, which comprises the G-protein coupled receptor calcitonin-receptor-like receptor (CRLR) and the receptor-activity-modifying protein 1 (RAMP1). The humanized CGRP receptors of the present invention attain pharmacological profiles similar to the wild type human receptor via modifications to the respective mammalian RAMP1 nucleotide sequence, specifically at amino acid 74. Also described are related recombinant vectors, recombinant hosts and associated methods for generating such humanized CGRP receptors. Also presented are non-human transgenic animals which express humanized RAMP1. Such animals have been engineered to provide for a CGRP pharmacological profile similar to human CGRP.Type: GrantFiled: September 26, 2002Date of Patent: March 20, 2007Assignee: Merck & Co., Inc.Inventors: Stefanie A. Kane, Christopher A. Salvatore, John J. Mallee, Kenneth S. Koblan, Kevin R. Oliver
