Scheduling

The implementation of a synthetic vaccine development platform for COVID-19 applications requires the following Tasks. 

Select Ii-Key-SARS-CoV-2 Epitope Peptides for Final Vaccine Formulation

to

Advance to Human Clinical Trials

Task 1: Manufacture 33 Laboratory Grade Ii-Key Peptide Vaccines

(The number of epitopes to be determined-see below) (Completed in US)

Party B has produced 33 laboratory-grade Ii-Key peptides for use in screening blood samples of people in the United States. According to the needs of the cooperative research team, Party B will produce more laboratory-grade Ii Key peptides (each small-scale production of about 20 mg) for screening the convalescent blood and serum samples of the entire population 

Task 2: Screen Ii-Key-Epitope Peptides against convalescent serum from the all populations (All the population, in US, has completed)

Party B is currently screening the 33 Ii-Key-SARS-CoV-2 peptides against convalescent blood samples from COVID-19 recovered patients at a commercial laboratory and at an academic research institute in the U.S. to evaluate T-Cell activity and ability to bind neutralizing antibodies. The final Ii-Key polypeptide vaccine formulation will be grouped by HLA type. 

NOTE: Because the Ii-Key is specific for human HLA complexes and HLA varies across ethnic populations, the Ii-Key-SARS-CoV-2 epitope peptides that work in the U.S. population may not be optimal for the East Asian population. Therefore, following the U.S. blood screening program, analyzing the T-Cell response data, and evaluating the HLA interactions of the Ii-Key-SARS-CoV-2 peptides, the cooperative research team will mutually determine which Ii-Key epitope peptides are optimal for the Chinese population, and conduct additional in-vitro T-Cell assays using convalescent blood samples from patients who have recovered from COVID-19 to develop vaccines to be used in China. Party B will provide technical solutions for T cell detection to the cooperative research team.

Task 3: Conduct Immunogenicity study of Ii-Key-Epitope Peptides in the DR4 humanized transgenic mouse model with Human HLA (complete by US and China team)

NOTE: Because the Ii-Key is specific for human HLA complexes to activate human CD-4 responses, animals will not respond the same as humans to Ii-Key Peptide Vaccines. Human Ii-Key does not bind to animal MHC complexes to activate animal CD-4 responses. Therefore, transgenic animal models with human immune cells are needed for immunogenicity trials in animals. Party B has plans to evaluate the U.S. formulation of the Ii-Key-SARS-CoV-2 vaccine in mouse immunogenicity studies using the DR4-Transgenic mouse model. Party B will provide the study report to Party C for filing with the NMPA. If the pre clinical study reports are not sufficient for the NMPA, Party C agree to conduct any and all pre-clinical and immunogenicity studies required by the NMPA to enable human clinical trials in China.

Task 4: Manufacture GMP Ii-Key-SARS-CoV-2 Vaccine

Manufacture medium-scale, GMP-grade multivalent Ii-Key-SARS-CoV-2 Peptide Vaccine for Phase I and Phase II human clinical trials - 10 to 100 g each peptide depending on final protocol.

Milestone: Manufacture, fill & finish Ii-Key-SARS-CoV-2 Peptide Vaccine to meet standards of the NMPA for Phase I and Phase II human clinic studies

Task 5: Phase I and Phase II Human Clinical Trials (China and the U.S. proceed simultaneously)

Early stage clinical trials to evaluate the safety and dose of the final Ii-Key­SARS-Co V-2 Peptide Vaccine in health adults (18 - 55 years old). Single or with a booster shot 14-21 days from initial dose, ascending dose study of peptide administered via sub-cutaneous injection with and without adjuvant. Party B will provide The Joint Entity with the currently planned clinical study design and protocol for the Phase I and II clinical trials upon technology transfer. The final protocol will be determined by the regulatory requirements of the NMP A. 

Milestone I: The Phase I study is designed to allow selection of the optimal dose of Ii-Key-SARS-CoV-2 Peptide Vaccine (and adjuvant) that produces the strongest, yet safe, immunological response.

Milestone II: The Phase II study is designed to provide sufficient safety data to enable Phase III human clinical trials of the Ii-Key-SARS-Co V-2 vaccine to evaluate the efficacy and safety in the all populations.

Task 6: Manufacture large-scale Ii-Key-SARS-CoV-2 peptide vaccine (In China)

Manufacture large-scale, GMP production of a multivalent the Ii-Key­SARS-CoV-2 Peptide Vaccine for Phase III human clinical trials - 1 KG each peptide.

Milestone: NMPA approval to manufacture Ii-Key-SARS-CoV-2 Peptide Vaccine for Phase III human clinic studies and commercial use

Task 7: Conduct Phase III clinical studies of Multivalent Ii-Key Peptide Vaccine in Large Population (26 weeks - 3 years) (Territories and countries where have a large Asian population, such as California and New York)

Conduct Large-scale immunization study in certain number of volunteers (number to be decided by regulatory authorities) to evaluate the safety, immune activation, and efficacy of the Ii-Key-SARS-CoV-2 Peptide Vaccine. The protocol will be designed to evaluate the safety and effectiveness of the vaccine to protect people from COVID-19 disease.

Milestone: Meet the product requirements of NMPA and the Department of Immunization of the National Health Commission to approve the production and sale of Ii-Key-SARS-CoV-2 peptide vaccine products.
