Conditions
Brief summary
This is a phase I study to evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Immunogenicity of RC1416 injection via Subcutaneous Administration in Healthy Adult Volunteers.
Detailed description
RC1416 is a bispecific homodimer nanobody .It is being developed by Nanjing RegeneCore Biotech Co., Ltd. as a potential therapy for asthma. A total 48 healthy adult subjects will be enrolled in six groups to access the safety and tolerability of single subcutaneous injection of RC1416 in healthy adult subjects.
Interventions
