About this study

Official title: Clinical Study of the Efficacy of the Ophthalmic Solution of Pazufloxacin 0.6% (PRO-157) for the Treatment of Acute Bacterial Conjunctivitis, Compared to the Ophthalmic Solution of Gatifloxacin 0.3%.

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.

Read more

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).

Read the detailed 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: will be evaluated at the end of the treatment (day 8, final visit)

  2. 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.

    Measured: will be evaluated at the end of the treatment (day 8, final visit)

Secondary outcomes (4)
  1. 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.

    Measured: will be evaluated at the end of the treatment (day 8, final visit)

  2. 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.

    Measured: will be evaluated at the end of the treatment (day 8, final visit)

  3. 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

    Measured: day 0 to day 17 (visit 0 to security call)

  4. 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".

    Measured: will be evaluated at the end of the treatment (day 8, final visit)

A Phase 3 study testing Pazufloxacin and Zymar in people with Conjunctivitis, Bacterial, run by Laboratorios Sophia S.A de C.V. at 6 sites in Mexico.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 24 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Aug 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Amount of Conjunctival Secretion Present in Each Patient by the End of Treatment (time frame: will be evaluated at the end of the treatment (day 8, final visit)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Aug 2021.
