clinical study of the efficacy of the ophthalmic emulsion pro-145 for inflammation and pain after phacoemulsification

Conditions: Cataract

Summary: objective: to evaluate the efficacy of the ophthalmic emulsion pro-145 in the treatment of inflammation and pain after phacoemulsification. hypothesis: the use of the ophthalmic emulsion pro-145 is effective in decreasing the inflammatory response evaluated by means of cellularity in the anterior chamber, after phacoemulsification. methodology: phase iii clinical trial, double-blind, controlled, parallel group, multicentre, randomized. number of patients: 178 subjects divided into 2 groups (89 subjects per group), who will provide an eye for the evaluation of efficacy. diagnosis and main inclusion criteria: diagnosis: postoperative phacoemulsification and foldable intraocular lens placement in a bag.

the study subjects will be recruited from various research centers in western and central mexico. each research center has a monitoring plan specified according to the recruitment capabilities of the same, which must be at least once a month, where the queries of your data entered into the electronic case report report will be reported to the center. (e-crf) for which it has as time limit the next monitoring visit to make the pertinent changes. the report of adverse events will be made according to the standard operating procedure (pno) where it specifies, according to official mexican standard 220 (nom 220), that the signs or symptoms of adverse events will be reported based on the medical dictionary. for regulatory activities, for which the sponsor has version 20.1 in spanish. for serious adverse events (saes) will be reported in accordance with the standardized operation procedure of pharmacovigilance of the sponsor, which adheres to the guidelines of nom 220 and international regulations, these will be reported in the regulatory framework to the regulatory entity within a period of time no more than 7 days. the study is registered in the national registry of clinical trials (rnec), entity equivalent to clinical trials in mexico. the quality assurance plan is carried out by the sponsor through the quality assurance agent in clinical research, whose function is to conduct inspections and audits of the research sites to document and generate reports of deviations from the protocol. in addition to the visits of the monitoring plan, the reliability of the data is guaranteed. to verify the integrity, veracity and reliability of the data entered into the e-crf, the monitors of each center will check the information uploaded to the portal with that reported in the source document of the principal investigator (pi), such as clinical notes, clinical history and documents. and formats attached to the research protocol, physical case report format, as well as those provided by the sponsor to the pi (subject's diary and quality and satisfaction survey). the e-crf used for this clinical study is provided by an internationally certified provider with the highest quality standards, protection of information under current regulations and confidentiality guarantee. the information that the pis enter into the e-crf is collated and verified by the clinical monitors and by the service provider's personnel, later reviewed and approved by the medical ophthalmologist researcher and by the clinical security pharmacologist, who authorize the monitored data of clinical information and safety of the study molecule, respectively.
