The goal of this clinical trial is to understand if Resomelagon can treat adult patients with Dengue virus infection. The main questions the investigators aim to answer are: Is Resomelagon safe to use in patients with Dengue? Is Resomelagon able to reduce the duration of illness? (defined by clinical and laboratory criteria) Participants will be allocated to Resomelagon or placebo groups in this study and asked to take the medication and submitted to blood tests.
Complications of dengue infection follows the peak of viremia and are associated with increased activation of the immune response. Proof-of-concept studies in animal models of dengue infection have shown that blocking certain aspects of the inflammatory response or the administration of pro-resolving molecules is beneficial in experimental dengue. In these experiments, the administration of certain anti-inflammatory or pro-resolution molecules decreases disease severity and aspects of the inflammatory response, including changes in vascular permeability. We have previously shown that treatment with RESOMELAGON decreased lung inflammation and outcome in animal models of beta coronavirus infection (including by SARS-CoV-2) and decreased disease severity in COVID-19 patients, even in the presence of glucocorticoid therapy. Preclinical experiments also showed that RESOMELAGON decreased disease severity in an animal model of dengue infection and decreased cytokine release by human PBMC infected with dengue virus. RESOMELAGON is safe in healthy individuals, those with rheumatoid arthritis, and patients with COVID-19. This is a placebo controlled, randomized, double-blinded clinical trial evaluating the safety and efficacy of Resomelagon in patients with acute dengue infection.

Incidence of clinical or laboratory adverse events. All symptoms, illness and laboratory abnormalities will be graded by the investigators in accordance to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Adverse events graded 3 or more in severity will be registered. Serious adverse events will be reported and registered. Incidence of adverse events will be compared between placebo and intervention groups.
Time frame: 28 days
