RCGM And CDSCO Recommends Fast Track Processing Of Recombinant Vaccines Applications For COVID-19

RCGM and CDSCO recommends Fast Track Processing of Recombinant Vaccines Applications for COVID-19

All over the world, scientists are working around the clock to find a vaccine against COVID-19. Global experts estimate that a fast-tracked vaccine can bring a vaccine to market in approximately 12-18 months – if the vaccine development process goes smoothly from conception to market availability.

The Central Drugs Standard Control Organisation (CDSCO) and Review Committee on Genetic Manipulation (RCGM) recommends the rapid processing of recombinant vaccine development during COVID-19 pandemic under Rapid response Regulatory Framework. All the applications will be screened depending on the proper data and population.

Key Highlights of the Guidance Note

  • Checklist of the conduct of pre-clinical toxicity (PCT) studies for recombinant vaccine development for COVID-19.
  • Consideration of the evidence of preclinical data outside India and analysis of the quality of data regarding the vaccine
  • Parallel application for clinical trial and PCT studies to CDSCO and RCGM, respectively.
  • Consideration of data on clinical studies generated outside India and abbreviated pathway for vaccine based on scientific rationale and level of completeness of data in human trials.

AGeneral
The Vaccine production platform (live viral vector, DNA, Yeast/ cell line expression, etc.) and the anticipated end product (DS) substantiated with published literature regarding its quality attributes, safety and immunogenicity. Substantiation can be with unpublished literature as well (in-house research, patent needs, etc.). In such cases there should be substantial documentation like manuscripts, inhouse documents, etc.
A1The application to contain Table of contents, all pages serially numbered, and all cited annexure(s) included in the final application.Required
A2Approval(s) accorded so far for the product under development by IBSC, RCGM, IAEC, etc. approved by CPCSEA, etc. (approvals as per proforma and guidelines may be provided later when covid-19 pandemic improves.Firm should apply for the appropriate approvals. Rolling submission allowed.
A3Describe source of material (isolate, lab, country)Required
BMolecular Characterization
B1Describe origin of gene(s) coding the molecule under consideration (isolate, lab, organization country)Required
B2Provide Nucleotide and translated protein sequencesRequired
