Clinical Trial Summary

Phase III clinical study of non-inferiority, multicenter, double-blind, with comparative group, of parallel groups and randomized. about a ophthalmic topical antibiotic for the treatment of bacterial conjunctivitis.

Goal:To compare the efficacy of the ophthalmic solution of pazufloxacin 0.6%, against the ophthalmic solution of gatifloxacin 0.3%, in the treatment of acute bacterial conjunctivitis.

Hypothesis:the ophthalmic solution PRO-157 is not inferior in the treatment of bacterial conjunctivitis, compared to the ophthalmic solution of gatifloxacin 0.3%, by means of the clinical remission of the disease.

Number of patients:

160 patients, each one will provide an eye for efficacy analysis, divided into 2 groups (80 eyes per group).

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Amount of Conjunctival Secretion Present in Each Patient by the End of Treatment	The ocular secretion will be classified as 0 = absent, 1 = mild, 2 = moderate and 3 = severe. The number will be reported according to the rating granted at final visit.	will be evaluated at the end of the treatment (day 8, final visit)
Primary	Severeness of Conjunctival Bulbar Hyperemia in Each Patient by the End of Treatment	Conjunctival hyperemia is defined as the simplest reaction of the conjunctiva to a stimulus, a red appearance secondary to the vasodilation of the conjunctival vessels of variable intensity. Will be graduated using the Efron scale.; 0 Normal , 1 Very slight, 2 Mild, 3 Moderate, 4 Severe.	will be evaluated at the end of the treatment (day 8, final visit)
Secondary	Overall Rating (Global Qualification) of Product's Efficacy as Classified by Main Investigator by the End of Treatment	The global qualification of the investigator constitutes the integral judgment of the clinical picture of the subject, including signs and symptoms, after a routine ophthalmological evaluation and interrogation. It will be classified 0 = cure, 1 = improvement, 2 = no changes compared to before starting treatment, 3 = worsened. It will be registered in the CRF in each of the follow-up visits.	will be evaluated at the end of the treatment (day 8, final visit)
Secondary	Presence of Bacterial Eradication Compared to Baseline Culture Results	The conjunctival secretion sample will be taken prior to the instillation of any medication, the result of the basal crop will be compared against the results of the final crop and the absence of bacterial species that were present in the culture of the baseline visit is considered bacterial eradication.	will be evaluated at the end of the treatment (day 8, final visit)
Secondary	Adverse Events	The evaluation of adverse events requires a questioning conducted by the principal investigator and the appropriate exploratory techniques for its detection. the number of adverse events per study group will be considered for the analysis	day 0 to day 17 (visit 0 to security call)
Secondary	Presence of Clinical Remission Defined as Absence of Hyperemia and Secretion by the Final Visit	The clinical remission in the visits will be evaluated as "Yes" or "No", to report "Yes" it must have a grade of "0" in conjunctival hyperemia and "0" in secretion; otherwise, you must report as "No".	will be evaluated at the end of the treatment (day 8, final visit)
