SVV-001 is unique among members of the Picornaviradae family in that transgenes can be inserted into the SVV-001 genome and expressed specifically within the tumor. Transgenes can code for proteins to provide additional safety over non-specific treatments. Transgenes coding for immune-modulatory elements further enhance the anti-cancer immune response. Transgenes that code for proteins can eliminate negatively modulate elements within the tumor that suppress the anti-tumor response. Versions of SVV-001 are also being constructed to encode tumor antigens.
ANti-cancer activity
Seneca Therapeutics currently has an open IND for a Clinical Trial titled “ A Phase 1 Trial of the Oncolytic Virus SVV-001 in Combination with Nivolumab in Patients with Poorly Differentiated Neuroendocrine Carcinomas and Well-Differentiated Neuroendocrine Tumors” We will be using an SVV-001 companion diagnostic (biomarker) to determine if a patient’s tumor is likely to be respond to SVV-001 in combination with checkpoint inhibitor therapy.
SVV variants are currently being developed to target many difficult-to-treat solid tumor cancer indications. Some of our armed viruses are in the pre-clinical development stage.
neutralizing antibody evasion
Our program aims to develop complimentary approaches to evade neutralizing antibodies that will enable successful multiple intravenous administrations of SVV-001.
LIBRARY TECHNOLOGY
Capsid mutagenesis to identify mutants that evade nAb
Capsid modifications to incorporate DARPINs
Genome saturation mutagenesis (to improve virus stability and new insertion sites)
3D polymerase mutagenesis to reduce recombination
