In an exchange filing, the company said it has received the approval from Drug Controller General of India - Central Drugs Standard Control Organisation (DCGI-CDSCO) to initiate Phase I/II human clinical trials for its Covid-19 (plasmid DNA) vaccine. The company has completed preclinical development and plans to begin the trials in July 2020, it said.
In animal studies, the vaccine was found to elicit a strong immune response in multiple animal species like mice, rats, guinea pigs, and rabbits. The antibodies produced by the vaccine were able to completely neutralize the wild type virus in virus neutralization assay, indicating the protective potential of the vaccine candidate, Cadila Healthcare said.
No safety concerns were observed for the vaccine candidate in repeat dose toxicology studies by both intramuscular and intradermal routes of administration. In rabbits, up to three times the intended human dose was found to be safe, well tolerated and immunogenic, it said.
The company intends to now rapidly ramp up the production capacities of ZyCoV-D at multiple sites and facilities to cater to Indian and global demand.
