COVID-19 Ring-based Prevention Trial With Lopinavir/Ritonavir (CORIPREV-LR)
Coronavirus Infections, Post-exposure Prophylaxis
About this trial
This is an interventional prevention trial for Coronavirus Infections
Eligibility Criteria
Inclusion Criteria:
High risk close contact with a confirmed COVID-19 case during their symptomatic period, including one day before symptom onset, within the past 1-7 days. High risk close contact is defined as any of the following exposures without the consistent appropriate use of recommended personal protective equipment:
- Provided direct care for the index case
- Had close physical contact with the index case
- Lived with the index case
- Had close contact (within 2 metres), without direct physical contact, for a prolonged period of time
- Had direct contact with infectious body fluids, including oral secretions, respiratory secretions, or stool.
- Successfully contacted by the study team within 24 hours of study team notification of the relevant index COVID-19 case. This time window is necessary because the efficacy of PEP may be dependent on the timing of its initiation, and because randomization of a ring cannot be delayed while awaiting response from contacts that cannot be rapidly reached.
- Age ≥6 months, since the safety and pharmacokinetic profiles of LPV/r in pediatric patients below the age of 6 months have not been established.
- Ability to communicate with study staff in English
Exclusion Criteria:
- Known hypersensitivity/allergy to lopinavir or ritonavir.
- Current use of LPV/r for the treatment or prevention of HIV infection.
- Receipt of LPV/r in the context of this trial or any other trial of COVID-19 PEP within 2 days or less prior to the last known contact with the index COVID-19 case. The two day time window is intended to ensure that exposure would not have occurred in the presence of clinically relevant drug levels (five times the elimination half-life of LPV/r, which is estimated at 4-6 hours with prolonged use).
- Baseline respiratory tract specimen positive for COVID-19. Randomized participants whose baseline samples subsequently show COVID-19 will have study drug discontinued but still remain under observation.
- Current breastfeeding, due to potential for serious adverse reactions in nursing infants exposed to LPV/r
Concomitant medications with prohibited drug interactions with LPV/r that cannot be temporarily suspended/replaced, including but not restricted to: 37

- rifampin (e.g. Rimactane®*, Rifadin®, Rifater®*, Rifamate®*)
- St. John's Wort
- Tadalafil (e.g. Adcirca®)
- venetoclax (e.g. Venclexta®)
- lovastatin (e.g., Mevacor®*), lomitapide (e.g., JuxtapidTM) or simvastatin (e.g., Zocor®)
- vardenafil (e.g., Levitra® or Staxyn®)
