EFFICACY:

  • 2  double-blind, placebo-controlled, randomized clinical field efficacy studies  and one environmental exposure chamber (EEC) study, n = 2,500, ODATRA vs. placebo
  • Primary Endpoint: Difference in  average Total Combined Rhinitis Score ( TCRS) during last 8 weeks of treatment; other endpoints average rhinitis daily symptom scores(DSS) and rhinitis daily medication scores (DMS)
  • 16 to 18 %  reduction in symptoms and need for additional medications vs, placebo

SAFETY:

  • Most commonly reported adverse reactions: Nausea, itching in the ears and mouth, and swelling of the lips and tongue
  • Boxed warning: Severe  allergic reactions

Neurovascular Thrombus Retrieval Catheters and Neurovascular Guide Catheters

 Used During Neurological Interventional Procedures

  • 510(k) premarket review and cleared indications are significantly different with differences in device design
  • Differences in FDA Review and Intended Use
Thrombus Retrieval Catheters Guide Catheters
Product Code: NRY  Product Code: DQY
Indications: Typically cleared with the indication for restoring blood flow or removal of thrombus within a blood vessel in the brain during an acute ischemic stroke within 8 hours of symptom onset in patients who are ineligible for or fail intravenous tissue plasminogen activator (IV t-PA) therapy. Indications: Typically cleared with the indication of introducing interventional devices into the neurovasculature or as a conduit for retrievers.
Performance Data: Typically, clearance of neurovascular thrombus retrieval catheters for this type of indication is based on non-clinical (e.g., bench and animal) performance data and, when necessary, clinical performance data. CDRH reviews these data to evaluate the ability of the device to safely navigate into the tortuous neurovasculature in close proximity to the thrombus and remove the thrombus to revascularize the blood vessel. Performance Data: Typically, clearance of neurovascular guide catheters for this type of indication is based on bench performance data to support the use of the catheter for the introduction of other interventional devices. Review of animal or clinical data is usually not required. In addition, neurovascular guide catheters are not reviewed for use in aspiration within the vessel for removing thrombus.
