Ravidasvir (PPI-668) is an investigational NS5A inhibitor (by Pharco Pharmaceuticals) in clinical trials for chronic hepatitis C genotype 4. [1]

It is on the World Health Organization's List of Essential Medicines. [2]

On December 11, 2024 it was approved in Russia under the trade name Konesko for the treatment of chronic hepatitis C in adult patients (only in combination with sofosbuvir). In the pivotal clinical trial STORM-C-1, the majority of patients were infected with HCV genotypes 1 or 3. Data from this study in patients with HCV genotypes 2 and 6 are limited, and data on patients with genotypes 4 or 5 are not available. [3]

Preliminary clinical trial results were announced in Nov 2015. [4] In April 2017, press reports stated that a combination treatment involving ravidasvir and sofosbuvir had achieved a 97% clearup rate against hepatitis C in a clinical trial conducted in Malaysia and Thailand, and 100% in another conducted in Egypt. [5] It has been granted conditional registration by the National Pharmaceutical Regulatory Agency (NPRA) of Malaysia. [6] [7]
