Cavatak is the trade name for a preparation of wild-type Coxsackievirus A21 (CVA21) developed by the Australian biotechnology company Viralytics Ltd. for the treatment of malignant melanoma[1][2][3] and other cancers such as breast, prostate[4] and head and neck cancer.[5]

Pre-clinical research[edit]

Within the Picornaviradae family of viruses, Coxsackievirus A21 (CVA21) is a member of the Human enterovirus C species. The virus consists of a single positive-stranded RNA genome within a capsid of approximately 28 nm in diameter. The virus is known to utilise the viral entry receptor ICAM-1 as its primary entry receptor, with DAF as a co-receptor to infect host cells.[6] Traditionally known as a common-cold virus that causes mild upper respiratory tract infections, the anti-cancer properties of this virus for the destruction of malignant melanoma cells was first published in 2004.[7] The proposed mechanism of CVA21 oncolysis is through the preferential targeting of melanoma cells that over-express the molecules ICAM-1 and/or DAF compared to normal cells.

CVA21 has also been found to have preclinical activity against breast[8] and prostate[9] cancer and multiple myeloma.[10]

Clinical trials[edit]

Cavatak is currently in Phase II clinical trials for the treatment of malignant melanoma.[3] This is an open label study, and classified as a safety/efficacy study. Outcome measures will include immune-related Progression-Free Survival (irPFS) at 6 months, Durable Response Rate at 6 months, 6 month Progression-Free Survival, 1 year Survival, Overall Survival and provide information on the safety of intratumorally administered Cavatak and Quality of Life.
