PROPEL™ Absorbable steroid-releasing sinus implant

LOCALIZED DRUG DELIVERY

Add the PROPEL family of implants to your ACTION plan

The PROPEL family of implants offers 3 steroid-eluting implants under one brand, allowing ENTs to select the best option that conforms to the anatomical needs of their patients1,2

Strengthen your sinus surgery action plan with the PROPEL family of implants, an innovation in sinus technology

PROPEL is the FIRST FDA-approved steroid-eluting sinus implant4

PROPEL implants feature an innovative 2-in-1 mechanism that opens in the sinuses while delivering mometasone furoate, a potent corticosteroid to the sinus mucosa, directly where it is needed1,2

OPENS in the sinus cavity

  • Self-expanding design that opens in and supports the sinus cavity1
  • Non-obstructive design allows for nasal clearance and the delivery of topical rinses1
  • Dissolvable frame over approximately 30-45 days after placement as the sinus cavity heals14

DELIVERS Mometasone furoate (MF) locally

  • Delivers 370 μg of MF over 30 days
  • MF present in the mucosal tissue for up to 60 days5 (based on pre-clinical data)

Drug Characteristics Comparison6-8
data displaying results of mometasone furoate vs. other topical corticosteroids

* Lipophilicity numbers normalized relative to triamcinolone acetonide.
As measured by relative receptor binding affinity compared to dexamethasone, which is set to a value of 100. Higher values designate greater potency.
As measured by plasma concentration of drug from intranasal vs intravenous route.

Mometasone furoate was selected for use in PROPEL implant for its optimal sinonasal drug characteristics10:

*   Postoperative intervention is a composite of need for surgical interventions to separate adhesions and/or need to prescribe oral steroids for inflammation.
   Judged by an independent reviewer or independent panel.
   Judged by clinical investigators.

PROPEL study design: Meta-analysis of two prospective, randomized, double-blinded multicenter studies (Pilot and ADVANCE II) that enrolled 143 patients.

Treatment following frontal sinus surgery with a full arsenal of options, including PROPEL Mini and PROPEL Contour, may help improve patient outcomes.
