NCT04082754

Brief Summary

This is a phase 1, first-in-human (FIH), multi-center, randomized, double-blind, placebo-controlled study of CSL311 in patients with mild-to-moderate asthma. The primary objective of this study is to assess the safety and tolerability of single ascending doses (SAD) and multiple ascending doses (MAD) of CSL311.

  • Percentage of subjects with related TEAEs in SC single dose, SAD and MAD (SC and IV)

    After infusion or injection, up to Day 85 for Cohorts A1 to A7, Day 57 for Cohort A8, Day 114 for Cohort B1 and Day 85 for Cohorts C1 to C3

  • Percentage of subjects with TEAEs by severity in SC single dose, SAD and MAD (SC and IV)

    Severity of TEAEs defined as mild, moderate, or severe

    After infusion or injection, up to Day 85 for Cohorts A1 to A7, Day 57 for Cohort A8, Day 114 for Cohort B1 and Day 85 for Cohorts C1 to C3

Secondary Outcomes (28)

Data Sharing

IPD Sharing
Will share

CSL will consider requests to share Individual Patient Data (IPD) from systematic review groups or bona-fide researchers. For information on the process and requirements for submitting a voluntary data sharing request for IPD, please contact CSL at clinicaltrials@cslbehring.com. Applicable country specific privacy and other laws and regulations will be considered and may prevent sharing of IPD. If the request is approved and the researcher has executed an appropriate data sharing agreement, IPD that has been appropriately anonymized will be available.

Shared Documents
STUDY PROTOCOL, SAP
Time Frame
IPD requests may be submitted to CSL no earlier than 12 months after publication of the results of this study via an article made available on a public website.
Access Criteria
Requests may only be made by systematic review groups or bona-fide researchers whose proposed use of the IPD is non-commercial in nature and has been approved by an internal review committee. An IPD request will not be considered by CSL unless the proposed research question seeks to answer a significant and unknown medical science or patient care question as determined by CSL's internal review committee. The requesting party must execute an appropriate data sharing agreement before IPD will be made available.
