Sorrento Announces Rapid COVISTIX COVID-19 Virus Antigen Test Detects Omicron Variant


  • COVISTIX maintains its ability to detect the Omicron variant, in addition to detecting SARS-CoV-2 and all of its major variants of concern (VoC);
  • COVISTIX has the potential to be a ‘best in class’ COVID-19 virus antigen rapid test:
    • Comparative studies with all EUA approved COVID-19 virus antigen rapid detection assays have shown that COVISTIX significantly outperforms in terms of limit of detection (LOD) of live N-proteins and / or viruses of SARS- CoV-2 and its main VoCs; and
    • In a large clinical field study under real conditions for all, including asymptomatic patients, COVISTIX demonstrated approximately 20% higher sensitivity compared to a leading global brand (detailed results are available at: https: // www / content / 10.1101 / 2021.09.10.21263410v1);
  • COVISTIX is currently approved and marketed in Mexico, Brazil and is CE marked in Europe;
  • Sorrento is building a new US domestic production facility in San Diego, California with an automated assembly line targeting an initial capacity of six (6) million COVISTIX tests per month;
  • Sorrento is also in talks with several US states for incentive programs to further expand its manufacturing capacity in the US pending strong US and global demand for COVISTIX testing; and
  • By combining OEM and in-house manufacturing capabilities, Sorrento is positioning itself to deliver 30 million COVISTIX tests per month in the short term and grow to 50-100 million COVISTIX tests per month to meet accelerating global demand.

SAN DIEGO, December 27, 2021 (GLOBE NEWSWIRE) – Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”) today announced that the first tests of COVISTIX on recombinant N proteins have demonstrated its ability to detect the variant Omicron, in addition to detecting the original SARS-CoV-2 virus and its other major VoCs such as delta and delta-plus strains. COVISTIX detection levels were similar for all variants. The ease of use and rapid detection of infection with Omicron was demonstrated by a recent case report of a Mexican patient infected with the Omicron variant first detected with COVISTIX within approximately 15 minutes of testing time. This result was confirmed a day later by RT-PCR and the sequence was verified a few days later as being an infection with Omicron.

In the laboratory, Sorrento also studied the ability of COVISTIX to detect the Omicron variant against other rapid COVID-19 virus antigen tests approved by the Emergency Use Authorization (EUA) and available in the trade. The first laboratory results show that COVISTIX was able to detect the Omicron N protein at a level significantly lower than that of other commercially available tests. With difficulty in detecting Omicron N protein at low levels, some of the rapid tests approved and marketed by the EUA may struggle to detect Omicron infection with reasonable sensitivity. False negative readings for asymptomatic infected patients could lead to a false sense of security and the inability to control outbreaks and perform normal social and business routines.

Sorrento currently has the capacity to produce 30,000,000 COVISTIX tests per month and is currently strengthening its manufacturing capacity in the United States. The company plans to have a fully automated assembly line capable of producing 6,000,000 COVISTIX units per month operational in the first quarter of 2022. Pending US and global demand, this capacity could potentially be increased to over 100 million. per month in 2022.
