Abstract: The present invention provides an approach for developing an algorithm for determining the effectiveness of anti-viral drugs based on a comprehensive analysis of paired phenotypic and genotypic data guided by phenotypic clinical cut-offs. In one aspect, the algorithm allows one to provide a patient with effective treatment. It helps predict whether an infected individual will respond to treatment with an anti-viral compound, thereby allowing an effective treatment regimen to be designed without subjecting the patient to unnecessary side effects. Also, by avoiding the administration of ineffective drugs, considerable time and money is saved.

Abstract: The present invention provides methods for determining the susceptibility of a pathogenci flavirus to anti-viral compounds. This invention also provides methods for determining anti-viral drug susceptibility in a patient infected with a flavivirus. This invention also provides a method for evaluating the biological effectiveness of a candidate anti-viral drug compound. The methods are useful for identifying effective drug regimens for the treatment of flaviviral infections, and identifying and assessing the biological effectiveness of potentia therapeutic compounds. Compositions including resistance test vectors and host cells transformed with resistance test vectors are provided.
