Phase-3 clinical trial enrolment for India's first dengue vaccine to be completed by October: ICMR
Synopsis India's DengiAll vaccine trial is nearing completion. ICMR scientists anticipate enrolling 10,500 participants by October across 20 Indian centers. The phase III trial assesses the Panacea Biotec's one-shot dengue vaccine. Initial trials showed no safety concerns. Participants will be monitored for two years to evaluate efficacy. This is a crucial step as India currently lacks a licensed dengue vaccine. Agencies Representational image Enrolment of about 10,500 participants in the phase III clinical trial of the indigenous one-shot Panacea Biotec developed dengue vaccine, DengiAll, is likely to be completed by October across 20 centres in India, according to ICMR far, 8,000 participants in various centres at Pune, Chennai, Kolkata, Delhi and Bhubaneswar among others have received either the vaccine or a placebo as part of the trial sponsored by the Indian Council of Medical Research (ICMR) and Panacea Biotec. The trial is co-led by ICMR-National Institute of Translational Virology and AIDS research in Pune, National Institute of Epidemiology (NIE), Chennai and National Institute of Virology, there is no antiviral treatment or licensed vaccine against dengue in results of the Phase-1/2 trial has shown no safety concerns for the one-shot vaccine, NIE Director Dr Manoj Murhekar said. "The participants enrolled in the Phase- III trial will be followed up for two-years. This trial will evaluate the efficacy of this tetravalent dengue vaccine," Dr Murhekar multi-centre, double-blind, randomised, placebo-controlled phase-III trial was launched in August last year to evaluate the jab's efficacy, safety and, long-term immunogenicity. The first participant in this trial was vaccinated at the Pandit Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences (PGIMS), Rohtak last year. The development of an effective vaccine is complex due to the need to achieve good efficacy for all four serotypes. The dengue virus has four serotypes, 1-4, with low cross-protection against each other, meaning individuals can experience repeated infections, Dr Murhekar said. In India, all four serotypes of dengue virus are known to circulate or co-circulate in many regions. The Union Health Ministry in a statement earlier had said that the tetravalent dengue vaccine strain (TV003/TV005), originally developed by the National Institutes of Health (NIH), USA, has shown promising results in clinical trials in Brazil. Panacea Biotec, one of three Indian companies to receive the strain, is at the most advanced stage of development. The company has worked extensively on these strains to develop a full-fledged vaccine formulation and holds a process patent for this work. Dengue is a major public health concern in India, ranking among the top 30 countries with the highest incidence of the disease. The global incidence of dengue has been steadily increasing over the past two decades, with more than 129 countries reporting dengue viral disease by the end of 2023, according to the World Health Organisation (WHO).In India, approximately 75-80 per cent of infections are asymptomatic, yet these individuals can still transmit the infection through the bite of Aedes mosquitoes. Among the 20-25 per cent of cases where symptoms are clinically apparent, children are at a significantly higher risk of hospitalisation and mortality. In adults, the disease can escalate into severe conditions like dengue hemorrhagic fever and dengue shock syndrome. According to the government data, around 12,043 dengue cases were reported till March this year. In 2024, 2.3 lakh cases and 297 deaths had been recorded.

Enrolment in third phase clinical trials for India's first dengue vaccine nearly complete, says ICMR
Following an announcement by the Indian Council of Medical Research (ICMR) and Panacea Biotec Limited to initiate third phase trials, about 8,000 of the targeted 10,000 participants have enrolled in the third phase of clinical trials for a dengue vaccine in India, Manoj Murhekar, Director, National Institute of Epidemiology, ICMR, Chennai, told The Hindu. The trial will be rolled out at 20 centres across the country, Dr. Murhekar said. 'In India, all four serotypes of the dengue virus are known to circulate or co-circulate in many regions, so it's vital to ensure that we have an effective vaccine that achieves good efficacy for all four serotypes,'' he added. The trial is primarily funded by ICMR, with partial support from Panacea Biotec. Participants will be followed up for two years under projects spread across various centres, including Chennai, Pune, Hyderabad, and Delhi. There is currently no antiviral treatment or licensed vaccine for dengue in India. 'This landmark trial will evaluate the efficacy of India's indigenous tetravalent dengue vaccine, DengiAll, developed by Panacea Biotec. The first participant in this trial was vaccinated last year at Pandit Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences, Rohtak,'' a release issued by the Union Health Ministry said. The tetravalent dengue vaccine strain (TV003/TV005) originally developed by the National Institutes of Health, the U.S., has shown promising results in preclinical and clinical trials worldwide. Panacea Biotec, one of three Indian companies to receive the strain, is at the most advanced stage of developing a vaccine. The company has worked extensively on these strains to develop a full-fledged vaccine formulation and holds a process patent for this work. The first and second phases of the clinical trials of Indian vaccine formulations were completed in 2018-19, yielding promising results. Dengue is a major public health concern in India, which ranks among the top 30 countries with the highest incidence of the disease. The global incidence of dengue has been steadily increasing over the past two decades, with more than 129 countries reporting dengue viral disease by the end of 2023, according to the World Health Organization (WHO).

Dengue vaccine a step closer? India's first phase 3 trial hits 50% enrolment mark, early data shows no safety concerns
India has reached the 50 per cent enrolment mark in its first phase III clinical trial for the indigenous tetravalent dengue vaccine, DengiAll, with over 7,000 participants randomised across 20 trial sites. Initial results show no safety concerns for the one-shot vaccine to fight the mosquito-borne viral disease, according to researchers. Developed by Panacea Biotec Limited under a licensing agreement with the National Institutes of Health (NIH), the primary US federal agency for biomedical research, DengiAll targets all four dengue virus subtypes and has shown promising results in earlier clinical trials. What is the dengue vaccine DengiAll about? DengiAll has a weakened form of all four dengue virus subtypes and has the same virus composition as the vaccine developed by NIH, except for the inactive ingredients. The NIH also evaluated the vaccine in the US and the results were found to be promising in the early-stage clinical studies. A Phase I and II clinical trial conducted in India revealed a balanced and robust immune response across all four dengue virus types. The vaccine was also found to be safe and well-tolerated. Multiple ICMR institutes are involved in the study to evaluate the efficacy, immunogenicity and safety of DengiAll. The ICMR-National Institute of Translational Virology (NITVAR) and AIDS Research (formerly ICMR-NARI) is responsible for overall trial coordination. Dr Sheela Godbole, director, ICMR-NITVAR and national principal investigator of the trial, told The Indian Express that the follow-up will be completed in the last quarter of 2027. According to Dr Abhijit Kadam, national co-principal investigator, healthy adults in the 18-60 year age group are being screened and randomised to receive either the dengue vaccine or a placebo (2:1). 'They will be followed up for two years,' he said. Dr Suchit Kamble, principal investigator for the NITVAR clinical trial site, explains that the vaccine would help in prevention of a disease that has no treatment. 'Some of the infections could result in severe manifestations like bleeding and sudden drop in blood flow and may threaten the life of the patient,' he said. The 20 trial sites are located in the following cities: Chennai, Pune (with two sites), Mysuru, Hyderabad, Puducherry, Kochi, Jodhpur, Ranchi, Kolkata, Aligarh, Patna, Rohtak, Ludhiana, Bengaluru, New Delhi, Bhubaneswar, Rishikesh, Guwahati, and Faridabad. The research teams at these sites come from well-known medical institutions, including three affiliated with ICMR. Dengue fever is one of the top 10 threats to global health, according to the World Health Organisation (WHO). India accounts for a large fraction of global dengue cases and the disease is endemic (regularly occurring within an area or community) in certain regions. Data from the National Centre for Vector Borne Diseases Control, Ministry of Health and Family Welfare, shows that till March this year, around 12,043 dengue cases were reported, while 2.3 lakh cases and 297 deaths were reported in 2024.
