Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment Bioresorbable Nasal Dressing, PuraSinus, for post-sinus surgery care?

Research shows that using absorbable nasal dressings, like PuraSinus, after sinus surgery can improve healing and reduce complications. Studies on similar treatments have found that they help with wound healing and patient comfort by reducing inflammation and promoting recovery.12345

Is PuraSinus safe for use in humans?

Research on similar biodegradable materials, like NovoSorb, shows they are generally safe, with minimal harmful effects on human cells and no toxic effects in animal studies. These materials are used in medical applications without causing significant side effects, suggesting a good safety profile.678910

How is the PuraSinus treatment different from other post-sinus surgery treatments?

PuraSinus may be unique in its approach to post-sinus surgery care by potentially using a novel combination of materials or drugs, similar to how other treatments use absorbable nasal packings with added medications like steroids or antibiotics to improve healing and reduce complications. This could offer advantages in comfort and effectiveness compared to traditional removable nasal packings.111121314

What is the purpose of this trial?

This trial tests PuraSinus, a new gel used after sinus surgery to help the nose heal better. It aims to make recovery more comfortable by stopping bleeding, reducing inflammation, and preventing scarring in patients who have had sinus surgery.

Eligibility Criteria

This trial is for adults over 18 with chronic sinusitis who need and agree to bilateral endoscopic sinus surgery (ESS). They must meet specific criteria based on the American Academy of Otolaryngology guidelines. Those allergic to shellfish, undergoing chemotherapy/immunotherapy, with immune deficiencies or coagulation disorders, or in another clinical trial can't participate.

Inclusion Criteria

You have been diagnosed with a condition called CRS according to specific medical guidelines.
I have agreed to sinus surgery for both sides of my nose due to ethmoid disease.

Exclusion Criteria

I have a blood clotting disorder.
You have an allergy to shellfish.
I am currently receiving chemotherapy or immunotherapy for another condition.

Findings from Research

The study found that three variants of NovoSorb, a biodegradable polyurethane, are biocompatible and safe for use as dermal scaffolds, showing minimal cytotoxic effects on human skin cells and no systemic toxicity in rat models.
NovoSorb demonstrated effective integration and healing in a sheep model, providing a promising foundation for a two-stage burn treatment strategy that stabilizes wounds and supports skin regeneration.
