Shire Says Lifitegrast Did Not Meet Prespecified Co-Primary Endpoint
Shire plc (NASDAQ: SHPG), the global specialty biopharmaceutical company, today announced top-line results from OPUS-2, a Phase 3 efficacy and safety study of 5.0% lifitegrast ophthalmic solution. OPUS-2 compared lifitegrast to placebo administered twice daily for 84 days (12 weeks) in dry eye patients with history of active artificial tear use within 30 days prior to screening. Lifitegrast met the prespecified co-primary endpoint for the patient-reported symptom of eye dryness (change in Eye Dryness Score from baseline to week 12) (p-value<0.0001). Lifitegrast did not meet the prespecified co-primary endpoint for the sign of inferior corneal staining score (change from baseline to Week 12) using fluorescein staining compared with placebo (p-value=0.6186).
"In this clinical trial, we note that lifitegrast showed a statistically significant improvement in the prespecified symptoms of dry eye disease and is the first drug to do so in a phase 3 clinical trial," said Flemming Ornskov, M.D., Chief Executive Officer, Shire. "We will be examining the totality of the data for lifitegrast in OPUS-2, as well as OPUS-1 and across the entire clinical trial program. We look forward to discussing the lifitegrast program with regulatory authorities."
The study also evaluated the safety and tolerability of lifitegrast based on occurrence of treatment-emergent adverse events (TEAEs). The most commonly reported TEAEs associated with lifitegrast were dysgeusia (altered sense of taste) (16.2% vs 0.3% for placebo), instillation site irritation (7.8% vs 1.4% for placebo), instillation site reaction (7.0% vs 1.1% for placebo) and visual acuity reduced (5.0% vs 6.4% for placebo). There were no ocular serious TEAEs or drug-related serious TEAEs. 93.2% of patients enrolled in the study remained for the entire duration of the 12-week clinical trial.
