The research focus of my group is providing knowledge-based translational solutions for strengthening the fight against the dengue menace. Based on our “know-how”, a 3-in-1 dengue test (Dengue Day 1) has been developed by an Indian company for simultaneous point-of-care detection of Dengue NS1 Antigen & differential detection of IgM & IgG antibodies in Human Serum/ Plasma. This Dengue Day 1 kit which was launched in 2011 today becomes the first line testing kit for the dengue diagnosis. It has been a phenomenal success with 100% sensitivity and 99.91% specificity. This kit is able to detect all four dengue virus serotypes and could diagnose both primary and secondary infections.
There are no effective antivirals against dengue and this boosted our quest for the development of a botanical drug that could be used against this disease. Based on Ayurveda’s knowledge and bioassay guided approach, we identified Cissampelos pareira (CIPA) that has natural anti-dengue potential. Clinical development of CIPA is being pursued under AYUSH guidelines in collaboration with Sun Pharma.
In addition to dengue diagnostics and anti-dengue botanical drug, efforts are being made to develop a safe, affordable and efficacious dengue vaccine candidate in collaboration with Sun Pharma. Despite decades of research efforts, the dengue vaccine has remained elusive. Recently approved whole virus-based dengue vaccine (Dengvaxia) is facing several limitations. It is effective only in age group of 9-45 years who are previously exposed to dengue virus. It has concerns of efficacy in dengue naïve individuals and it seems to cause disease enhancement in children and is contraindicated.
An ideal dengue vaccine should elicit dengue virus neutralizing immune responses which are devoid of any potential of disease enhancement. Our group has designed a recombinant subunit virus like particle based tetravalent dengue vaccine candidate that elicits virus neutralizing antibodies in the absence of any significant disease enhancing immune responses. This vaccine is targeted for all age groups in both dengue endemic and non-endemic areas.
