PF-03715455 is a potent p38 inhibitor, showing some selectivity for p38-alpha over p38-beta. PF-03715455 inhibited IL-6, MCP-1, MIP1β, CC16 and CRP levels in plasma of healthy subjects. PF-03715455 was optimized for delivery by inhalation. PF-03715455 substantially reduced tobacco-smoke--induced lung neutrophilia and inflammatory damage to the lungs. PF-03715455 had been in phase II clinical trial for the treatment of asthma and phase I clinical trial for the treatment of chronic obstructive pulmonary disease. However, these investigations were discontinued.
