Abstract
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 harbor 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.
Claims12
A batch of recombinant replication-defective adenovirus based upon adenovirus serotype 5 (Ad5), the recombinant replication-defective adenovirus comprising a chimeric hexon protein, wherein in the chimeric hexon protein hypervariable region sequences HVR1 to HVR7 of Ad5 have been replaced with those of Ad48 or of Pan9, in the following manner:
- the HVR1 sequence of Ad5 (SEQ ID NO:
- 17) has been replaced by a sequence selected from the group consisting of SEQ ID NO:
- 24, and 52,
- the HVR2 sequence of Ad5 (SEQ ID NO:
- 18) has been replaced by a sequence selected from the group consisting of SEQ ID NO:
- 25, and 53,
- the HVR3 sequence of Ad5 (SEQ ID NO:
- 19) has been replaced by a sequence selected from the group consisting of SEQ ID NO:
- 26, and 54,
- the HVR4 sequence of Ad5 (SEQ ID NO:
- 20) has been replaced by a sequence selected from the group consisting of SEQ ID NO:
- 27, and 55,
- the HVR5 sequence of Ad5 (SEQ ID NO:
- 21) has been replaced by a sequence selected from the group consisting of SEQ ID NO:
- 28, and 56,
- the HVR6 sequence of Ad5 (SEQ ID NO:
- 22) has been replaced by a sequence selected from the group consisting of SEQ ID NO:
- 29, and 57, and
- the HVR7 sequence of Ad5 (SEQ ID NO:
- 23) has been replaced by a sequence selected from the group consisting of SEQ ID NO:
- 30, and 58, and
- wherein the sequences between the HVR sequences are from Ad5.
A recombinant adenovirus comprising a chimeric hexon protein, wherein the sequence of the chimeric hexon protein consists of SEQ ID NO:
- 12.
A batch of recombinant replication defective adenovirus based upon adenovirus serotype 5 (Ad5), the recombinant replication-defective adenovirus, comprising a chimeric hexon protein, wherein the chimeric hexon protein hypervariable region sequences HVR1 to HVR7 of Ad5 have been replaced with those of Ad48 in the following manner:
- the HVR1 sequence of Ad5 (SEQ ID NO:
- 17) has been replaced by an amino acid sequence consisting of SEQ ID NO:
- 24,
- the HVR2 sequence of Ad5 (SEQ ID NO:
- 18) has been replaced by an amino acid sequence consisting of SEQ ID NO:
- 25,
- the HVR3 sequence of Ad5 (SEQ ID NO:
- 19) has been replaced by an amino acid sequence consisting of SEQ ID NO:
- 26,
- the HVR4 sequence of Ad5 (SEQ ID NO:
- 20) has been replaced by an amino acid sequence consisting of SEQ ID NO:
- 27,
- the HVR5 sequence of Ad5 (SEQ ID NO:
- 21.) has been replaced by an amino acid sequence consisting of SEQ ID NO;
- 28,
- the HVR7 sequence of Ad5 (SEQ ID NO:
- 22) has been replaced by an amino acid sequence consisting of SEQ ID NO:
- 29, and
- the HVR7 sequence of Ad5 (SEQ ID NO:
- 23) has been replaced by an amino acid sequence consisting of SEQ ID NO:
- 30, and wherein the sequences between the HVR sequences are from Ad5.
