APT™ T3X on the COVID-19 Contamination Rate

The new coronavirus 2019 (COVID-19) was declared a pandemic by the World Health Organization (WHO), due to the alarming levels of spread, severity and inaction. Dealing with COVID-19 must be done on different fronts, such as mitigation, treatment and prevention. Therefore, strategies and therapies that can help reduce the COVID-19 rate of contamination are still important alternatives at this time of the pandemic. The Advanced Penetration Technology™ (APT™) is intellectual property owned by Patient Focused Tele-Health, LLC, a Rockwall, Texas based company. The company's focus is improving over-the-counter (OTC) topical formulations, allowing consumers better therapeutic outcomes with non-prescription medications. The Advanced Penetration Technology™ (APT™) is a patent-pending, proprietary transdermal dual carrier formulation. This formulation provides improved dermal penetration and efficacy of topical API's. Additionally, the APT™ imparts both a mechanical and biochemical effect on the microbe/fungal cell walls providing a highly effective method of destruction of microbes. These unique properties impart the broad spectrum anti-viral capability to the APT™ Tetracycline 3% formulation, breaking barriers in pharmacology and virology. The topical formulation APT™ Tetracycline 3% formulation (APT ™ T3X), is a FDA registered, Non-Prescription product. This formulation is used in an off label manner as an intranasal application for prevention of COVID-19 and other viruses. The APT™ T3X as a topical application will penetrate through and into the mucus layer and deeper. This barrier of coverage will provide a mitigation effect to decrease the viral load of exposure and infection. The efficacy of APT™ T3X is due to disrupting the lipid envelope in seconds, hence neutralizing the virus. Previous tests were performed with APT™ T3X and the results found were promising. However, these tests were performed only in vitro and clinical studies demonstrating the ability of the APT™ T3X to decrease viral exposure and contamination by COVID-19 are necessary to confirm the possible prophylactic effect, allowing the formulation to be widely distributed to the general population. Therefore, the aim of this project is to evaluate the efficacy of the APT™ T3X compared to placebo to decrease COVID-19 contamination rate in humans.

To achieve the proposed objective it will be performed a randomized, triple blind, placebo-controlled trial. The volunteers will be randomly allocated to two intervention groups: APT™ T3X or placebo. The volunteers will be blinded to the treatment received. One hundred volunteers will be recruited for the study (50 volunteers per group). As this is a preliminary study, the number of volunteers was determined by a convenience sample. The volunteers randomly allocated to the two groups will be instructed to use the APT™ T3X or placebo, once a day, every day for 21 days (except health professionals that will be instructed to use APT™ T3X or placebo twice a day, every day for 21 days). All data will be collected by a blinded assessor. The investigators will analyze: COVID-19 contamination rate. Presence of adverse events. Number of adverse events. Frequency of adverse events. Other virus or bacteria contamination rate. Statistical analysis: The results obtained will first be tested for normality using the Kolmogorov-Smirnov test. The chi-square test or Fisher's exact test for two independent proportions will be used in the statistical analysis of the primary outcome of this study, the COVID-19 contamination rate and for the secondary outcomes: presence of adverse events and other virus or bacteria contamination rate. For the other secondary outcomes, the number of adverse events and frequency of adverse events, the Wilcoxon test will be used if this outcome does not present a normal distribution. If this outcome presents a normal distribution, the two-tailed, unpaired t test will be used. The level of significance used will be 5% (p <0.05).

A participating researcher not involved in the recruitment and evaluation of the volunteers will carry out the randomization process. This researcher will be instructed not to disclose the randomization codes in the intervention groups to any of the volunteers and to the other researchers involved in the study, until its completion. The intervention bottles will be exactly the same regardless of whether it is APT™ T3X or placebo.
