  1. Willing and able to provide informed consent

  2. Male or female patients > 18 years of age on the day of informed consent

  3. Have received a confirmed diagnosis of COVID-19 (positive for SARS CoV 2), as assessed by PCR or point-of-care within 72 hours of first dose on Day 1

  4. Have mild to moderate signs or symptoms of COVID-19 with onset within 5 days of first dose on Day 1, at least two of the following symptoms:

     • stuffy or runny nose
     • sore throat
     • shortness of breath
     • cough
     • fatigue
     • myalgia

     • feeling hot or feverish
     • nausea
     • vomiting
     • diarrhea
     • anosmia
     • ageusia

  5. Outpatient with COVID-19 disease (not requiring oxygen therapy [WHO COVID-19 Clinical Improvement Ordinal Scale, score of 3])

  6. Patient is aware of the investigational nature of this study and willing to comply with protocol treatments, blood tests, and other evaluations listed in the informed consent form (ICF).

Exclusion criteria

• Patients will be excluded from the study if they satisfy any of the following criteria unless otherwise stated:

  1. Females who are pregnant (negative pregnancy test required for all women of child bearing potential at Screening) or breast-feeding
  2. Male patients and women of childbearing potential (women who are not surgically sterile or postmenopausal defined as amenorrhea for >12 months) who are not using at least one protocol specified method of contraception
  3. Severe COVID-19 disease as defined by the WHO COVID-19 Clinical Improvement Ordinal Scale, scores of 5 (non invasive ventilation or high-flow oxygen), 6 (intubation and mechanical ventilation), or 7 (ventilation + additional organ support pressors, renal replacement therapy [RRT], extracorporeal membrane oxygenation [ECMO])
  4. Expected survival less than 72 hours
  5. Peripheral capillary oxygen saturation (SpO2) <90% while breathing room air
  6. Treatment with other drugs thought to possibly have activity against SARS CoV 2 infection like remdesivir, favipiravir, within 7 days prior to enrollment or concurrently
  7. History of abuse of drugs or alcohol that could interfere with adherence to study requirements as judged by the Investigator
  8. Use of any other concurrent investigational drugs while participating in the present study
  9. Patient requires frequent or prolonged use of systemic corticosteroids (≥20 mg of prednisone/day or equivalent for >4 weeks) or other immunosuppressive drugs (e.g., for organ transplantation or autoimmune conditions)
  10. Known renal disease with an estimated glomerular filtration rate (eGFR) <50 mL/min based on local laboratory results
  11. Patients with clinically apparent liver disease, e.g., jaundice, cholestasis, hepatic synthetic impairment, or active hepatitis
  12. Alanine transaminase (ALT) or aspartate transaminase (AST) >3 × upper limit of normal (ULN) or alkaline phosphatase or bilirubin levels > 2 × ULN based on local laboratory results
  13. Co administration of clinical doses of orlistat with dalcetrapib
  14. Inability to swallow oral medications or a gastrointestinal disorder with diarrhea (e.g., Crohn's disease) or malabsorption at Screening
  15. Any other clinically significant medical condition or laboratory abnormality that, in the opinion of the Investigator, would jeopardize the safety of the patient or potentially impact patient compliance or the safety/efficacy observations in the study
  16. History of an allergic reaction or hypersensitivity to the study drug or any component of the study drug formulation.
