Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Phase II, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy, Safety, and Tolerability of Intravenous huMAb OX40L (RO4989991) in the Prevention of Allergen-Induced Airway Obstruction in Adults With Mild Allergic Asthma

Primary Outcome Measures:
  • The primary outcome measure is the late asthmatic response (LAR) in patients treated with huMAb OX40L versus placebo [ Time Frame: 16 weeks after the first dose ]

Secondary Outcome Measures:
  • LAR after the allergen challenge in patients treated with huMAb OX40L versus placebo [ Time Frame: Approximately Day 56 prior to third dose ]
  • Change in methacholine challenge response relative to the pre-allergen challenge PC20 [ Time Frame: 24 hours after each allergen challenge ]
  • Early asthmatic response (EAR) in patients treated with huMAb OX40L versus placebo [ Time Frame: Between 0 and 2 hours after each allergen challenge ]
  • Incidence and nature of treatment-emergent adverse events [ Time Frame: Through study completion or early study discontinuation ]
  • Incidence and nature of infusion reactions [ Time Frame: Through study completion or early study discontinuation ]
  • Incidence of infectious complications [ Time Frame: Through study completion or early study discontinuation ]
  • Incidence, nature, relatedness, and severity of adverse events [ Time Frame: Through study completion or early study discontinuation ]
  • Clinically significant changes in vital signs, electrocardiograms, FEV1, and safety laboratory measures [ Time Frame: Through study completion or early study discontinuation ]
  • Incidence of anti-therapeutic antibodies [ Time Frame: Through study completion or early study discontinuation ]
