Ora's success is based on a foundation of scientific rigor applied to the drug development process. We have created many proprietary clinical models and protocols that produce high-integrity safety and efficacy data quickly. To catalyze continuous innovation, we dedicate considerable resources to understanding ophthalmic clinical research design, model innovation and evolution, endpoint development and evaluation, clinical trial processes, and management strategies. The advantages we offer our Sponsors are in no small part derived from Ora's unique culture, what we call "The Ora Way," which promotes operational excellence, aggressive project management, creative study design and implementation, personal accountability, outcome-focused decision making, and close involvement of technical experts on day-to-day issues.

Paul Gomes, MS, Director, has accrued 13 years of experience in successfully executing allergy programs and clinical-regulatory strategy. As Director of the Allergy Department at Ora, Paul's responsibilities include regulatory interface, protocol/model development, clinical program management, and data interpretation, and he has overseen over a hundred allergy clinical trials. Paul has published numerous articles on specific drugs and on allergic conjunctivitis. Under his supervision, six different allergic conjunctivitis clinical programs have been approved by regulatory bodies. Mr. Gomes's core staff includes ophthalmologists, optometrists, PhD's, and experienced clinical trial managers.

We are the only allergy group in the world with a dedicated Ora-CAC team of more than 15 full-time professionals surrounded by our internal cross-functional teams in education, quality assurance and quality control, recruiting, and regulatory affairs. Together, these experts run the Ora-CAC Model System repeatedly throughout the year. This year, Ora conducted its 500,000th Ora-CAC in the field of allergy research.
