This study is designed to compare the safety, tolerability, and pharmacokinetics of QBX258 (sequential administration of a fixed dose of VAK694 and single ascending doses of QAX576) in patients with well-controlled mild to moderate asthma.

Condition Intervention Phase
Drug: VAK694
Drug: VAK694 placebo
Drug: QAX576
Drug: QAX576 placebo
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Official Title: A Randomized, Double-blind, Placebo Controlled Study to Compare the Safety, Tolerability, and Pharmacokinetics of QBX258 (Sequential Administration of a Fixed Dose of VAK694 and Single Ascending Doses of QAX576) in Patients With Well-controlled Mild to Moderate Asthma

Further study details as provided by Novartis:

Primary Outcome Measures:
  • Number of patients with adverse events [ Time Frame: 100 days ]
    Adverse events will be determined by evaluating clinical, laboratory evaluations, impact on vital signs and impacts on ECGs

Secondary Outcome Measures:
  • Concentration of serum anti-VAK694 antibodies [ Time Frame: Pre-dose, Day 71, 85 and 100 ]
    Blood will be collected to determine concentrations if anti-VAK964 antibodies

  • Concentration of serum anti-QAX576 antibodies [ Time Frame: Pre-dose, Day 71, 85 and 100 ]
    Blood will be collected to determine concentrations if anti-QAX576 antibodies

  • Area under the serum concentration curve for VAK694 [ Time Frame: Pre-dose, 1, 2, 4, 11, 24, 48, 96 hours and Days 8, 15, 29, 43, 57, 71, 85, 100 ]
    Blood will be collected for the measurement of VAK694 serum concentrations

  • Area under the serum concentration curve for QAX576 [ Time Frame: Pre-dose, 1, 2, 4, 11, 24, 48, 96 hours and Days 8, 15, 29, 43, 57, 71, 85, 100 ]
    Blood will be collected for the measurement of QAX576 concentrations

  • Change in interleukin concentrations [ Time Frame: Pre-dose, 1, 2, 4, 11, 24, 48, 96 hours and Days 8, 15, 29, 43, 57, 71, 85, 100 ]
    Blood samples will be collected to measure interleukin concetrations.
