Hyderabad-based Bharat Biotech has commenced clinical trials of MTBVAC, the first Mycobacterium tuberculosis vaccine derived from a human source, in India. The trial will evaluate the vaccine’s safety, immunogenicity, and efficacy. Developed by Spanish biopharma player Biofabri in collaboration with Bharat Biotech, the live attenuated vaccine will have exclusive global manufacturing rights for newborns, adolescents, and adults.
MTBVAC is expected to be more effective and provide longer-lasting protection compared to the century-old BCG vaccine. It aims to prevent tuberculosis in newborns, adults, and adolescents, for whom there is currently no effective vaccine. Unlike the BCG vaccine, which has limited effectiveness against pulmonary TB, MTBVAC contains all the antigens present in strains that infect humans.
The clinical trials in India are crucial in advancing the development of the vaccine, considering it is the most populated country and has the highest number of TB cases. Biofabri CEO Esteban Rodriguez views this as a significant step, especially in a country where 28% of the world’s TB cases accumulate.
Bharat Biotech’s executive chairman, Dr. Krishna Ella, describes the trials in India as a major milestone in the quest for a more effective TB vaccine. The vaccine underwent over three decades of research and is currently the only TB vaccine undergoing clinical trials based on a genetically modified form of the pathogen.
MTBVAC’s development can be attributed to collaboration between Spain’s University of Zaragoza’s laboratory and Dr. Brigitte Gicquel of the Pasteur Institute in Paris. Biofabri serves as the industrial partner for Zaragoza University.
The vaccine recently completed a Phase-2 dose finding trial and is undergoing a Phase-3 clinical trial in newborns in South Africa, Madagascar, and Senegal. This trial compares MTBVAC with the BCG vaccine, which is currently the only TB vaccine in use.
Analyzing the implications of MTBVAC’s development and clinical trials, it becomes evident that this vaccine has the potential to revolutionize the prevention of tuberculosis. With its genetically modified form, MTBVAC aims to overcome the limitations of the BCG vaccine, providing better protection against pulmonary TB. This breakthrough could significantly reduce the transmission of the disease, especially in highly affected countries like India.
Furthermore, the collaboration between Bharat Biotech and Biofabri highlights the importance of international partnerships in the advancement of medical research. Such collaborations facilitate the exchange of knowledge, resources, and expertise, leading to groundbreaking innovations.
The ongoing clinical trials emphasize India’s role in the development of new vaccines and healthcare solutions. As the country with the highest number of TB cases, India provides a vital testing ground for MTBVAC. The results obtained from these trials will contribute to global efforts in combating tuberculosis and improving public health outcomes.
Looking into the future, the successful development and deployment of MTBVAC could pave the way for more advanced and effective vaccines against other infectious diseases. The use of genetically modified pathogens could become a standard approach in vaccine development, offering superior protection and reducing the burden of global health issues.
In conclusion, the commencement of clinical trials for MTBVAC marks a significant milestone in the fight against tuberculosis. The potential of this vaccine to provide more effective and longer-lasting protection holds immense promise for preventing the transmission of the disease. The collaborative efforts of Bharat Biotech, Biofabri, and international research institutions demonstrate the importance of global partnerships in advancing medical research. With continued support and investment in vaccine development, the future holds great potential for improved healthcare outcomes and the prevention of various infectious diseases.
