Study summary

Randomized study of single and multiple doses of BBT002 in healthy volunteers and in adult patients with chronic obstructive pulmonary disease (COPD) or chronic rhinosinusitis with nasal polyps (CRSwNP).

Read the detailed description

This study a is a randomized, double-blinded, placebo-controlled single (SAD) and multiple-ascending dose (MAD) study to evaluate safety, tolerability, pharmacokinetics, immunogenicity, pharmacodynamics, and exploratory clinical activity of BBT002 in healthy volunteers (HVs) and in adult patients with COPD or CRSwNP. BBT002 is a drug candidate being developed for the treatment of COPD or CRSwNP. BBT002 will be given by intravenous injection or subcutaneous injection.
