Status Withdrawn

Clinical Trial Summary

Evaluation of the efficacy and safety of hydroxychloroquine - camostat combination therapy in hospitalized patients with moderate COVID-19 infection, CLOCC-Trial Primary Objectives: The primary objective of this study is to demonstrate, that a combination therapy of hydroxychloroquine and camostat (Foipan®) is superior to hydroxychloroquine + placebo in participants with moderate COVID-19.

Clinical Trial Description

The ongoing pandemic with the novel coronavirus (SARS-CoV-2) poses a massive threat to public health. SARS-CoV-2 is highly contagious and may lead to severe acute respiratory distress syndrome in affected individuals. No therapeutic intervention has yet been approved for COVID-19, and initial interventional studies with single agents showed only minimal improvement in outcome or were not convincing in design. Therefore, the CLOCC trial will evaluate the efficacy and safety of a combination therapy consisting of hydroxychloroquine, which was used already as single agent with some effect, together with camostat mesylate in hospitalized patients with moderate COVID-19 infection. The rationale for this combination therapy stems from the observation that hydroxychloroquine interferes with viral entry and replication through several mechanisms including changes in endosomal pH and in glycosylation of the ACE2 receptor, which serves as entry receptor for SARS-CoV-2. Camostat acts as inhibitor of the host cell serine protease TMPRSS2, which is needed to prime the viral S protein for cell entry. Participants will be recruited in a total of 6 German centers, and the trial will be randomized (1:1) and enrolled in either the hydroxychloroquine + placebo or the hydroxychloroquine + camostat arm (7-day treatment). The trial will be carried out in a double-blinded fashion. The primary efficacy outcome is the number of patients discharged by day 14 (status 1 and 2 of a 7-point ordinal clinical status scale). Several secondary outcomes regarding efficacy but also safety will be evaluated. Exploratory endpoints include analysis of viral titers and the emergence of viral resistance in response to therapy. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
