A Phase 2 Study to Evaluate the Efficacy and Safety of TNX-102 SL in Patients With Multi-Site Pain Associated With Post-Acute Sequelae of SARS-CoV-2 Infection (PREVAIL)

November 18, 2024 updated by: Tonix Pharmaceuticals, Inc.

A Phase 2, 14-week Double-Blind, Randomized, Multicenter, Placebo-Controlled Study to Evaluate the Efficacy and Safety of TNX-102 SL Taken Daily at Bedtime in Patients With Multisite Pain Associated With Post-Acute Sequelae of SARS-CoV-2 Infection (PASC)

This is a Phase 2, randomized, parallel-group, double-blind, placebo-controlled, 14-week study designed to evaluate the efficacy and safety of TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) taken once daily at bedtime for the management of multi-site pain associated with Long COVID.

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

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Major Inclusion Criteria:

  • The patient is male or female, 18 to 65 years of age, inclusive.
  • The patient has a polymerase chain reaction (PCR) confirmed history of SARS-CoV-2 infection at least 3 months prior to enrollment, based on a documented written positive viral test at the time of active infection.
  • The patient has new onset or significant worsening of pain that coincides with a prior COVID-19 infection and has symptoms that have been generally present for at least 3 months but no longer than 18 months.

Major Exclusion Criteria:

  • The patient has been diagnosed with infectious or inflammatory arthritis (eg, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis), systemic lupus erythematosus, untreated or active gout (ie, any acute attack within past 2 years is exclusionary), or meets criteria for another type of systemic autoimmune disease (eg, Sjogren's disease).
  • The patient has been diagnosed with a complex regional pain syndrome, fibromyalgia, failed back surgery syndrome, persistent or prevalent pain symptoms related to systemic disease (eg, diabetic peripheral neuropathy, post-herpetic neuropathy), untreated hyperparathyroidism, or a history of prior surgery, trauma, organ or tissue damage, or other source of pain that, in the Investigator's opinion, would confound or interfere with the assessment of the patient's symptoms or require excluded therapies during the patient's study participation.

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
Daily Diary Pain NRS
Time Frame: Week 14
Change from Baseline in the diary Numeric Rating Scale (NRS) weekly average of daily self-reported worst Long COVID pain intensity scores at the Week 14 endpoint. Scores range from 0 to 10 where a higher score means worse outcome.
Week 14

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Daily Diary Sleep Quality NRS
Time Frame: Week 14
Mean change from baseline in the weekly average of the daily diary numeric rating scale (NRS) assessment of sleep quality at the Week 14 endpoint. Scores range from 0 to 10 where a higher score means worse outcome.
Week 14
PROMIS Fatigue -Short Form 8a
Time Frame: Week 14
Change from Baseline in the Patient Reported Outcomes Measurement Information System (PROMIS) score for fatigue at the Week 14 endpoint. Subjects are asked to reflect on their fatigue symptoms in the past 7 days and respond to 8 questions on a 5 point scale (1 to 5) where a higher score indicates a worse outcome. The total score is reported on a range of 8 to 40. Raw scores are converted to T-scores based on US population with score of 50 as average with a standard deviation of 10.
Week 14
PROMIS Cognitive Function - Abilities-Short Form 8a
Time Frame: Week 14
Change from Baseline in the Patient Reported Outcomes Measurement Information System (PROMIS) score for cognitive function at the Week 14 endpoint. Subjects are asked to reflect on their cognitive function and abilities in the past 7 days and respond to 8 questions on a 5 point scale (1 to 5) where a higher score indicates a worse outcome. The total score is reported on a range of 8 to 40. Raw scores are converted to T-scores based on US population with score of 50 as average with a standard deviation of 10.

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.
