About IFNAR

Interferon alpha/beta receptor (IFNAR) is a cell surface receptor complex mediating type I interferon effects, which are cytokines vital for immune responses. Binding of interferons to IFNAR triggers intracellular events, leading to the expression of genes involved in antiviral defense and immune modulation.

💡

IFNAR requires biologic approaches (enzyme), likely due to its structure or location.

The lack of small molecule or antibody drugs represents a whitespace opportunity for novel therapeutic modalities.

📈 Modality Evolution

2021 — Biologic (other) (SAPHNELO)
2021 — Enzyme (BESREMI)

other biologics pioneered IFNAR targeting (2021), with enzymes entering more recently (2021).

How We Count Trials

  • Trials: phase 1-4 interventional trials on ClinicalTrials.gov that started in 2008 or later and test an FDA-approved drug acting on IFNAR. A trial counts if an approved drug acting on IFNAR is in any arm, including as a comparator, and a trial that tests two such drugs counts once. Trials that test only unapproved drugs are not counted. A trial listed as phase 1/2 counts as phase 1, and phase 2/3 as phase 2.
  • Active: recruiting, not yet recruiting, enrolling by invitation, or active and no longer recruiting.
  • Completion rate: of the trials that have ended, the share marked Completed rather than Terminated or Withdrawn. Completed means the trial ended as planned; it does not mean the drug worked. Suspended trials are not counted as ended.
  • Stopped: terminated or withdrawn. Trials stop for many reasons, including slow enrolment and business decisions, not only safety or efficacy.
  • Sponsors: the lead sponsor of each trial. Companies are the sponsors ClinicalTrials.gov classes as industry; the rest are universities, hospitals, cooperative groups, government bodies and individuals.
