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

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.
