Safety and Efficacy of Thymic Peptides in the Treatment of Hospitalized COVID-19 Patients in Honduras

Phase 2

Completed

• Conditions: COVID-19
• Interventions: Biological: Thymic peptides

• Registration Number: NCT04771013
• Lead Sponsor: Universidad Católica de Honduras

Brief Summary

This is a single-arm, open-label, phase II clinical study to evaluate the safety and efficacy of thymic peptides in the treatment of hospitalized COVID-19 patients in Honduras.

Detailed Description

This study was approved and registered by the Dirección General de Vigilancia del Marco Normativo de la Secretaría de Salud de Honduras (General Directorate for Regulatory Framework Surveillance of the Ministry of Health of Honduras) the eight of February of 2021; enrollment began tenth of February of 2021.

The study will analyze 23 clinical parameters, 9 laboratory studies besides complete blood count, chest radiography, time to response, adverse clinical outcomes, and hospital length of stay in 22 participants treated with a daily oral dose of 250 mg of lyophilized thymic peptides dissolved in 50 mL of water (one hour before or two hours after a meal) in addition to the standard treatment. A participant-level comparison based on registry data from Hospital de Santa Bárbara Integrado will be performed after propensity score matching. The Generic Assessment of Side Effects in Clinical Trials (GASE) will be applied in addition to monitoring of treatment-emergent adverse events.

Arm && Interventions

Group	Intervention	Description
Daily oral dose of thymic peptides	Thymic peptides	Patients will receive a daily oral dose of 250 mg of lyophilized thymic peptides dissolved in 50 mL of water (one hour before or two hours after a meal) in addition to the standard treatment, for up to 20 days or until medical discharge.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Treatment Related Adverse Events as Assessed by the Common Terminology Criteria for Adverse Events Version 5.0	Up to 20 days	Number of participants who experience adverse events ≥ Grade 3, as defined by the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE v5.0).
Number of Participants With Treatment Related Side Effects as Assessed by the General Assessment of Side Effects	Up to 20 days	Number of participants who experience severe side effects as defined by the General Assessment of Side Effects (GASE).
Time to Participant Recovery	During hospitalization for up to 20 days.	Measured in days to clinical recovery that will be defined as the first day, during the 20 days after enrollment, on which a patient met the criteria for category 1, 2, or 3 on the eight-category ordinal scale. The categories are as follows: 1, not hospitalized and no limitations of activities; 2, not hospitalized, with limitation of activities, home oxygen requirement, or both; 3, hospitalized, not requiring supplemental oxygen and no longer requiring ongoing medical care; 4, hospitalized, not requiring supplemental oxygen but requiring ongoing medical care (related to Covid-19 or to other medical conditions); 5, hospitalized, requiring any supplemental oxygen; 6, hospitalized, requiring noninvasive ventilation or use of high-flow oxygen devices; 7, hospitalized, receiving invasive mechanical ventilation or extracorporeal membrane oxygenation (ECMO); and 8, death.

Secondary Outcome Measures

Name	Time	Method
Number of Participants That Died by Day 20	Up to 20 days	Number of participants that died due to any reason by day 20.
