Brief Summary:
Designed as a single center, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of EIDD-2801 on SARS-CoV-2 Virus Shedding in Newly Hospitalized Adults with polymerase chain reaction (PCR)-Confirmed COVID-19.

Condition or disease Intervention/treatment Phase
SARS-CoV 2 Drug: 200 mg EIDD-2801 Drug: 300 mg EIDD-2801 Drug: Placebo (PBO) Phase 2

Detailed Description:
Phase 2a randomized, placebo-controlled, double-blinded clinical trial of EIDD-2801 in adult men and women who have tested positive for severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection within 48 hours of polymerase chain reaction (PCR) confirmation and are hospitalized with a diagnosis of COVID-19. Rapid enrollment and treatment will be initiated such that the first dose of EIDD-2801 or placebo will be administered as soon as possible and within 7 days of onset of symptoms. The Data Safety and Monitoring Board will review interim results of the study to monitor safety of EIDD-2801.

    • At least one of the following symptoms: cough, shortness of breath, respiratory rate ≥ 20, radiographic evidence of pneumonia OR
    • Anosmia OR
    • other clinical symptoms or signs of COVID-19 that are not otherwise explained by comorbidities or co-diagnoses
  2. PCR+ test for SARS-CoV-2.
  3. Has new signs or symptoms of COVID-19 that began ≤7 days of anticipated first dose of study drug.
  4. Persons ≥18 years old.
  5. Prior to COVID-19 diagnosis was in good health and had controlled chronic conditions

    • defined by having stable dosing of medications for chronic medical conditions for at least 4 weeks prior to COVID-19 symptom onset.
  6. Is admitted to the Johns Hopkins Medical Institutions and anticipated to remain in the hospital for ≥ 24 hours.
  7. Is willing and able to comply with all study procedures including providing informed consent, collection of virology samples, and any safety tests that are not included as part of standard of care (SOC).
  8. Is willing and able to take oral medications, and is anticipated to be able to take the full course of 5 days of study agent.

    Pregnancy and Contraception: No developmental or reproductive studies of EIDD-2801 have been conducted. Therefore, treatment with EIDD-2801 is contraindicated in women who are pregnant and in the male partners of women who are pregnant. Extreme care must be taken to avoid pregnancy during the study and for 6 months after completion of EIDD 2801 dosing in female participants and in female partners of male participants who are taking EIDD 2801.

  9. Female participants of childbearing potential must meet the the following criteria to be enrolled:

    1. Have a negative pregnancy test at Screening
    2. Must agree to undergo a follow-up pregnancy test on Study Day 28.
    3. Must agree to use at least 2 forms of contraception during the study and for at least 50 days after dosing of the study drug is complete, as discussed with and approved by the investigator.

    OR Must have an azoospermic partner (vasectomized or due to a to medical cause) Note: azoospermic partner is acceptable provided that the partner is the sole sexual partner of the woman of childbearing potential and the absence of sperm has been confirmed.

    Note that female not of childbearing potential is defined as either:

    i. Surgically sterile: females who are permanently sterile via hysterectomy, bilateral salpingectomy, and/or bilateral oophorectomy by reported medical history and/or medical records. Surgical sterilization to have occurred a minimum of 6 weeks, or at the Investigator's discretion, prior to Screening. OR

    ii. Postmenopausal: Females at least 60 years of age with amenorrhea for ≥12 months (by history) or 45 years of age with amenorrhea for 12 months without an alternative medical reason with confirmatory follicle stimulating hormone levels of ≥40 mIU/mL. The amenorrhea should not be induced by a medical condition such as anorexia nervosa, hypothyroid disease or polycystic ovarian disease, or by extreme exercise. It should not be due to concomitant medications that may have induced the amenorrhea such as oral contraceptives, hormones, gonadotropin releasing hormones, anti-estrogens, or selective estrogen receptor modulators.
