A Study to Evaluate Safety, Tolerability, Pharmacokinetics and Pharmacodynamics in Health Subject

• Status: Unknown status
• Trial end date: 2020-08-01
• Target enrollment: 0
• Participant gender: All

Summary

SN1011 (the study drug), is currently being developed by Sinomab as a new drug for treating autoimmune disease (diseases occurring when your body's natural immune/defence mechanism attacks healthy tissue and nerves), such as rheumatoid arthritis (RA). RA causes recurrent joint pain and swelling, particularly in the hands and feet, and can lead to bone erosion and joint deformity.

SN1011 is known as a BTK inhibitor. Bruton's tyrosine kinase (BTK) is an enzyme that plays a key role in B-cell development, and B-cells play an important role in immunity throughout the body. It is thought that blocking the BTK signal may inhibit disease progression in people with RA and may even resolve the disease.

The purpose of this research study is to assess the safety and tolerability of SN1011 as well as the pharmacokinetics (PK - how your body handles the study drug) and pharmacodynamics (PD

• how the study drug affects your body) of the study drug. The investigators are doing this study in healthy men and women.
