Pune firm set to roll out cure for dengue

MUMBAI: Asia's largest vaccine maker, Pune-based Serum Institute will develop a biologic drug to treat all four strains of the dengue virus, and is in the process of applying to the Ministry of Science and Technology for a "fast-track approval" to roll-out the treatment in the country. The biologic treatment (monoclonal anti-body) once rolled out will be given as an injection to cure dengue, and cost between Rs 5,000-10,000 for a single dose. Only one dose will be required. Serum, which has tied up with US-based biotechnology company Visterra to use its technology to develop the monoclonal antibody, hopes to commercialize the treatment within 12-18 months of getting the regulatory approvals, Serum Institute CEO Adar Poonawalla told TOI.
While Serum's biologic drug could become one of the first treatments to roll out, other biggies like Sanofi and Novartis are also in the race to launch a vaccine may happen over the next few years.
"We hope that the government will give a fast-track approval to our application as dengue has assumed alarming proportions, and could become a public health crisis", Poonawalla told TOI, adding, it would then initiate clinical trials to prove its safety and efficacy on a few 100 to 1000 subjects. If the trials are successful, Serum could perhaps become the first company to offer a cure for the dreaded infection which has shown the worst outbreak, with several deaths, and cases doubling this year.
Under the terms of the agreement, Serum Institute has an exclusive license to commercialize the treatment for the Indian subcontinent, including India, Pakistan, Bangladesh, Nepal, Bhutan, Maldives, and Sri Lanka. It has paid Visterra a $5 million upfront payment, and up to $34 million based on the achievement of certain development and commercial milestones.
Serum Institute will fund and be responsible for the clinical development of VIS513 in the licensed territories, including the filing of regulatory applications. The companies will establish a joint steering committee to coordinate the development for the Indian subcontinent.
The Pune-based company is also working on a dengue vaccine, like the other global biggies to be given as a preventive. The development of a vaccine will take three to four years, as it has to be tested on a wide-range and number of subjects, he added.
Amongst the vaccines, Sanofi has emerged as a front-runner, having completed Phase II trials, a company official said.
About half the world's population is at risk of contracting the virus, with no specific treatment for dengue/ severe dengue, but early detection and access to proper medical care lowers fatality rates below 1%, according to the World Health Organization.
The market for the vaccine could be huge, and reach $400 million in 2020, according to GlobalData estimates, while others say it could more than triple, and bring in $1.4 billion a year at its peak.
Visterra's humanized monoclonal antibody, VIS513 has reportedly worked to neutralize all four serotypes of dengue virus, with the "animal model" studies showing promising results, he added. The US company is already running its own trials in Singapore, Serum will need to do clinical studies here on Indian subjects by importing the clone.
