Clinical Trial Summary

In the first human clinical trial conducted in the United States, single and multiple dosing of FB2001 in multiple dose groups were partially completed，and FB2001 demonstrated good safety and tolerability. The bridge study of FB2001 will be conducted in China to evaluated the safety and PK of FB2001 in healthy Chinese population. This is a randomized, double-blind, placebo-controlled study of single and multiple dosing.

Description:

Coronaviruses belong to the genus of coronavirus of the family coronaviruses. The viruses of the coronavirus genus are positive-sense single-stranded RNA viruses with envelopes, which are approximately 80-160 nm in diameter. Their genetic material is the largest among all RNA viruses and can infect both humans and animals. Coronaviruses can cause respiratory, intestinal, hepatic, and nervous system diseases of different severities. A total of 7 coronaviruses have been found, in which HCoV-229E, HCoV-OC43, HCoV-NL63 and HCoV-HKU1 mainly lead to mild and self-limiting upper respiratory tract infections in infected humans, such as common cold; two new types of β-coronaviruses have emerged in the past 12 years, namely severe acute respiratory syndrome (SARS-CoV) and Middle East respiratory syndrome (MERS-CoV), and these two viruses can cause severe human diseases.

In the first human clinical trial conducted in the United States, single and multiple dosing of FB2001 in multiple dose groups were partially completed，and FB2001 demonstrated good safety and tolerability. The bridge study of FB2001 will be conducted in China to evaluated the safety and PK of FB2001 in healthy Chinese population. This study is a randomized, double-blinded, placebo-controlled, ascending dose to evaluate the pharmacokinetics, safety and tolerability of FB2001 for injection afer a single and multiple dose administrations in healthy subjects. A total of 40 healthy subjects are planned to be enrolled. Each group will include 8 subjects.

5. History of tuberculosis or lung disease as reported by subject;

6. Subject has severe cardiovascular disease, neurological disease, hematological disease, infectious disease, mental disorder, liver disease, gastrointestinal disease, endocrine disease, immune disease or kidney disease, or has a history of the above diseases, or other symptoms known to interfere with the absorption, distribution, metabolism, or excretion of the medicine, or other conditions that the investigator believes will increase the risk of the subject and might interfere with the study conduct and results interpretations;

7. Female subjects who are pregnant, lactating or have pregnancy plans and cannot contracept as required;

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Evaluation of the safety and tolerability of FB2001 after a single and multiple dose administrations in healthy subjects	The safety and overall tolerability assessments will be evaluated based on: Incidence of Treatment-Emergent Adverse Events (TEAEs) and Adverse reactions (ADR); Incidence of grade 3 and 4 AEs/ADRs; Incidence of SAE; Incidence of drug-related serious adverse events	Day1 - Day 29
Primary	Pharmacokinetic parameter (AUC0-t)	Pharmacokinetic outcome measures: Estimate of steady state AUC0-t for single and multiple dose administration of FB2001	Day1 - Day 6
