Overview
Brief Summary
The goals of this clinical study were to assess the safety, tolerability, blood levels, and disease impact of UPB-101 when given to adults with mild asthma. Eligible participant were consecutively assigned to 1 of 3 to 5 planned treatment groups. Each treatment group consisted of 8 individuals, six of whom will received active drug (UPB-101) and 2 who received placebo. Neither the study doctors nor the participants knew which participants were assigned to active study drug and which were assigned to placebo. The study was performed at 4 experienced research sites in the United Kingdom.
Detailed Description
This was a two-part phase 1b, multi-center randomized, double-blind (Investigator and Subject blinded; Sponsor unblinded), placebo-controlled, multiple ascending-dose study to assess the safety, tolerability, immunogenicity, pharmacokinetics (PK), and pharmacodynamics (PD) of UPB-101 administered subcutaneously (SC) to adult subjects with asthma. The study consists of Part A and Part B. Part A included 3 cohorts with pre-set dosing regimens. Part B (optional) included up to 2 additional cohorts whose doses and dosing intervals decided based upon the safety, PK, and PD results from Part A (i.e., an adaptive design), as applicable. The regimens selected for Part B did not exceed the exposures (i.e., doses and/or dosing intervals) included in Part A. Eight subjects were randomized per cohort (6 active, 2 placebo). Thus, a total of 32 subjects were enrolled in the study with 24 subjects in Part A and 8 in Part B.
