| 20080199939 | Adenoviral Vectors and Uses Thereof - The present invention relates to recombinant adenoviral vectors based on adenoviruses that encounter pre-existing immunity in a minority of the human population and which harbour a chimeric capsid. The chimeric capsid comprises fiber proteins that have at least the knob domain of a human adenovirus that binds to the Coxsackievirus and Adenovirus Receptor (CAR) and a hexon protein from an adenovirus serotype that encounters pre-existing immunity in a low percentage of the human population. | 08-21-2008 |
| 20090123438 | Multivalent Vaccines Comprising Recombinant Viral Vectors - The invention relates to vaccines comprising recombinant vectors, such as recombinant adenoviruses. The vectors comprise heterologous nucleic acids encoding for at least two antigens from one or more tuberculosis-causing bacilli. The invention also relates to the use of specific protease recognition sites linking antigens through which the encoded antigens are separated upon cleavage. After cleavage, the antigens contribute to the immune response in a separate manner. The recombinant vectors may comprise a nucleic acid encoding the protease cleaving the linkers and separating the antigens. The invention furthermore relates to the use of genetic adjuvants encoded by the recombinant vectors, wherein such genetic adjuvants may also be cleaved through the presence of the cleavable linkers and the specific protease. | 05-14-2009 |
| 20100015176 | Settings for recombinant adenoviral-based vaccines - The present invention provides new uses of recombinant adenoviral vectors in vaccination regimens, such as prime/boost set-ups and subsequent vaccinations and applications for gene therapy. Moreover, the invention provides new assays to determine the best regimen for applying the most suitable recombinant viral vector in a vaccination or gene therapy setting. | 01-21-2010 |
| 20100311172 | Packaging cells for recombinant adenovirus - In the absence of substantial sequence overlap between a recombinant adenoviral vector and the genome of a packaging cell, helper-dependent E1-containing particles (HDEP) can be formed at low frequency. Provided are means and methods for reducing or preventing the generation of HDEP. To this purpose, novel packaging cells and methods of making these are provided. | 12-09-2010 |

| 20080199433 | Complementing cell lines - A packaging cell line that complements recombinant adenoviruses based on serotypes from subgroup B, preferably adenovirus type 35. The cell line is preferably derived from primary, diploid human cells that are transformed by adenovirus E1 sequences either operatively linked on one DNA molecule or located on two separate DNA molecules, the sequences being operatively linked to regulatory sequences enabling transcription and translation of encoded proteins. Also disclosed is a cell line derived from PER.C6 that expresses functional Ad35 E1B sequences. The Ad35-E1B sequences are driven by the E1B promoter or a heterologous promoter and terminated by a heterologous poly-adenylation signal. The cell lines are useful for producing recombinant adenoviruses designed for gene therapy and vaccination. The cell lines can also be used for producing human recombinant therapeutic proteins such as human growth factors and human antibodies. Also, the cell lines are useful for producing human viruses other than adenovirus such as influenza virus, herpes simplex virus, rotavirus, and measles virus. | 08-21-2008 |
| 20080206837 | Stable adenoviral vectors and methods for propagation thereof - Provided are methods and means to increase the stability and/or the packaging capacity of recombinant adenoviruses, by overexpression of pIX in an adenoviral packaging cell, by retaining at least a part of the E1B-55K region in the recombinant adenoviral vector or by regulating pIX with a heterologous promoter. The invention further relates to methods and means for the production of such adenoviruses on complementing cell lines, wherein the early region 4 open reading frame 6 (E4-orf6) encoding nucleic acid is present in the adenovirus and wherein the E4-orf6 gene product is compatible with one or more products of the E1 gene products in the complementing cell, such that the adenoviral vector can be efficiently produced by the complementing cell. | 08-28-2008 |

| 20090110695 | Compositions Comprising a Recombinant Adenovirus and an Adjuvant - The invention relates to pharmaceutical compositions comprising replication-defective adenoviruses, said adenoviruses generally comprising an adenoviral genome wherein a heterologous nucleic acid of interest is incorporated, and wherein said nucleic acid typically encodes an antigen. Such compositions are suitable for vaccination purposes. The pharmaceutical compositions of the present invention further comprise an adjuvant, which stimulates and increases the immune response towards the antigen encoded by the heterologous nucleic acid. Preferred adjuvants are oil-emulsion based adjuvants and aluminium-based adjuvants. | 04-30-2009 |
| 20100143302 | Recombinant Adenoviruses Based on Serotype 26 and 48, and Use Thereof - The present application relates to recombinant adenoviruses, more in particular those that encounter low levels of pre-existing neutralizing activity in hosts that are in need of treatment or vaccination. Particularly, the invention relates to recombinant vectors derived from two subgroup D adenoviruses: Ad26 and Ad48. | 06-10-2010 |

| 20100034774 | Serotype of adenovirus and uses thereof - Adenovirus serotypes differ in their natural tropism. The adenovirus serotypes 2, 4, 5 and 7 all have a natural affiliation towards lung epithelia and other respiratory tissues. In contrast, serotypes 40 and 41 have a natural affiliation towards the gastrointestinal tract. The serotypes described differ in at least capsid proteins (penton-base, hexon), proteins responsible for cell binding (fiber protein), and proteins involved in adenovirus replication. This difference in tropism and capsid protein among serotypes has led to the many research efforts aimed at redirecting the adenovirus tropism by modification of the capsid proteins. | 02-11-2010 |

| 20090253207 | Gene delivery vectors provided with a tissue tropism for smooth muscle cells, and/or endothelial cells - A gene delivery vehicle having been provided with at least a tissue tropism for cells selected from the group of smooth muscle cells, endothelial cells, and/or liver cells. The tissue tropism is generally provided by a virus capsid, such as one comprising protein fragments from at least two different viruses, such as two different adenoviruses, including adenovirus of subgroup C or subgroup B (for example, adenovirus 16). The protein fragments can comprise a tissue tropism-determining fragment of a fiber protein derived from a subgroup B adenovirus. Also, cells for producing such gene delivery vehicles and pharmaceutical compositions containing these gene delivery vehicles are provided. Further, a method is disclosed for delivering nucleic acid to cells such as smooth muscle cells and/or endothelial cells which involves administering to the cells an adenovirus capsid having proteins from at least two different adenoviruses and wherein at least a tissue tropism-determining fragment of a fiber protein is derived from a subgroup B adenovirus. Particular constructs are also disclosed. | 10-08-2009 |
