Therapeutic potential of the sphingosine kinase 2 inhibitor opaganib.
Review in Pharmaceutical science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Opaganib is a proprietary, host-directed, potentially broadly potent, first-in-class oral sphingosine kinase 2 (SphK2) selective inhibitor developed by RedHill Biopharma Tel Aviv, Israel. It is currently the most widely used selective SphK2 inhibitor. It simultaneously inhibits three sphingolipid-metabolizing enzymes in human cells-SphK2, dihydroceramide desaturase (DES1), and glucosylceramide synthase (GCS)-leading to depletion of sphingosine 1-phosphate (S1P), accumulation of ceramides and dihydroceramides, and suppression of key pro-survival pathways including pERK, pAKT, and NF-κB. These events promote autophagy, apoptosis, and disruption of viral replication. A large body of evidence indicates that SphK plays an important role in health and disease. This study reviews the role and mechanisms of opaganib effects as anticancer, anti-inflammatory, and antiviral agent. The latest research directions for opaganib are described as gastrointestinal acute radiation syndrome (GI-ARS), chemical exposure indications, and COVID-19, Ebola, and other viruses, providing new therapeutic ideas and considerations for future research and clinical trials.
