Bicalutamide to Block TMPRSS2 in Males With COVID-19 Infection

June 30, 2021 updated by: University of Florida

Randomized Trial of Bicalutamide to Block TMPRSS2 in Males With COVID-19 Infection

COVID-19 outcomes are worse in male patients. Androgen signaling, therefore, is a target for clinical exploration. TMPRSS2 is a membrane protease required for COVID pathogenesis that is regulated by androgens. Blocking TMPRSS2 with bicalutamide may reduce viral replication and improve the clinical outcome. Therefore, the study proposes to test bicalutamide at 150 mg oral daily dosing in a double-blind placebo-controlled randomized trial in male patients with early symptomatic COVID-19 disease.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
  • Phase 3

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years to 95 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

Subjects must meet all of the following criteria to be eligible for study participation:

  • Men ≥ 36 years old diagnosed with at least one temperature elevation ≥ 100.4 F., OR new cough, OR new dyspnea AND documented COVID-19 positive by approved standard local laboratory assay
  • Men ≥ 18 years but < 36 years old must exhibit EITHER new cough, OR new dyspnea AND documented COVID-19 positive by approved standard local laboratory assay.
  • Access to working telephone or other form of communication such as email.
  • Randomization within 7 days of COVID-positive study result. All subjects will undergo repeat COVID-19 assay on day 0 enrollment and a positive test is required to stay on study
  • Written informed consent obtained from the subject and the subject agrees to comply with all study-related procedures

Exclusion Criteria:

Subjects with any of the following will not be eligible for study participation:

  • Randomization greater than 7 days from a positive COVID test result. All subjects will undergo repeat COVID-19 assay on day 0 enrollment and a negative test will result in a screen-fail and removal from study
  • Admission to hospital at time of screening
  • Inclusion in another randomized trial for COVID therapy
  • Diagnosis of prostate cancer and/or treatment with anti-androgen in the past 3 months
  • Current treatment with any androgen replacement products
  • Prior allergic reaction or intolerance to Bicalutamide or other Androgen receptor Inhibitors
  • Requirement for coumarin product or warfarin products due to potential displacement by bicalutamide
  • Subject unable to take oral bicalutamide
  • Known Hepatitis B or C
  • Liver Cirrhosis
  • AST/ALT greater than or equal to 3 X institutional ULN

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Proportion x 100 = percent of patients with improved COVID-19 symptoms
Time Frame: Day 28
COVID-19 symptom relief at day 28, and % of COVID-19 symptom relief and its 95% confidence interval (CI) will be calculated using the exact binomial distribution and compared using Fisher's exact test.
Day 28

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
