Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this open-label study, a single dose of the corticosteroid Betamethasone Dipropionate Nasal Cream 0.0644% (equivalent to 0.05% Betamethasone) will be administered under endoscopic guidance to the sinus mucosa of post-FESS patients whose chronic rhinosinusitis (CRS) condition is suboptimal under the current standard of care. The safety and benefits of this treatment will be monitored by patient-reported symptoms and endoscopic assessment of the sinus mucosa.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • For each nostril, an endoscopic nasal polyp score of 0, 1, or 2 out of a maximum score of - (where 0= No polyps, 1= small polyps in the middle meatus not reaching below the inferior border of the middle turbinate , 2= nasal polyps reaching below the border of the middle turbinate, 3= large nasal polyps reaching the lower border of the inferior turbinate or nasal polyps medial to the middle turbinate, 4= large nasal polyps causing almost complete obstruction of the inferior nasal cavity) (Gevaert et al, 2023).
  • Visible middle turbinates and access to the ethmoid sinuses for dosing as established via endoscopic examination.
  • Participants must have a > 2 on the disease severity visual analogue scale (VAS) at screening and pre-treatment.
  • Body weight: A minimum body weight >=40 kilograms (kg) and a BMI of ≤ 39 at the screening visit.
  • Individuals of childbearing potential must use adequate birth control methods and not plan to get pregnant during the study.
  • Informed consent: Willingness to give written informed consent and willingness to participate in and comply with the study.
  • Age ≥18 but <80 years.

Exclusion Criteria:

  • Subjects with known hypersensitivity or contraindications to betamethasone dipropionate, mometasone, or topical anaesthesia.
  • Subjects with sino-nasal abnormalities, disease, or implanted devices that prevents the application of the therapy.
  • Previous enrolment in this study.
  • Subjects currently receiving systemic corticosteroid or have received systemic corticosteroid in the prior 4 weeks or receiving biologic therapy.
  • Subjects with a history of glaucoma or cataracts or have an abnormal intraocular pressure (IOP) at screening or pre-treatment (abnormal IOP is defined as greater than 21 mm Hg).
  • Subjects with acute sinusitis.
  • Subjects with known immunodeficiency.
  • Subjects with diabetes (Type 1).
  • Subjects with cystic fibrosis.
  • Pregnant subjects or subjects trying to get pregnant or currently lactating as the effect on human pregnancy is unknown.
  • Subjects who are unable to give an informed consent because of mental illness, dementia or communication difficulties.
  • Subjects with a Cushing's disease diagnosis within the previous 12 months.
  • Severe septal deviation and or previous total resection of the middle turbinate.
  • Any lab abnormality or underlying medical condition which, in the Investigator's opinion, should exclude the participant.
  • Subjects who are unlikely to comply with study procedures, restrictions and requirements as determined by the investigator.

Betamethasone Dipropionate Nasal Cream 0.0644% is applied topically to the inflamed tissue of the sinus using a pre-filled syringe and applicator under the guidance of an endoscope. Up to 5g on each side of the sinus (10g in total).
Device: Pre-filled syringe and applicator device
Cream is pre-filled to a syringe and applicator device to facilitate the topical application direct to the sinus under endoscopic guidance.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in 4-Cardinal Symptom score (4CSS) Baseline to Week 3.
Time Frame: Baseline through study completion, an average of 4 weeks
Change in average daily score prior to dosing (an average of 7 days) and the average daily score of the 7 days prior to exit (between week 2 and 3 weeks after dosing).Participants score their 4-Cardinal Symptom score (4CSS) daily on a Likert scale of 0-5; where 0= no problem - 5= problem as bad as can be, higher scores indicate higher severity of symptoms.
Baseline through study completion, an average of 4 weeks
Change in SNOT-22 Baseline to Week 3.
Time Frame: Baseline through study completion, an average of 4 weeks
Participants complete the Sino-nasal Outcome Test (SNOT-22) questionnaire at Baseline and Week 3, analysis will focus on the nasal symptom subdomain. The SNOT-22 measures 22 symptoms on a Likert scale of 0-5; where 0= no problem - 5= problem as bad as can be, higher scores indicate higher severity of symptoms. A higher total score indicates greater symptom severity.
Baseline through study completion, an average of 4 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Safety of one application of BMDP Cream onto the sinus mucosa.
Time Frame: Informed consent through study completion, an average of 3 weeks
Monitoring of morning serum cortisol levels, glucose levels, treatment emergent changes in other chemistry or haematology results deemed clinically significant by the Investigator, intraocular pressure, and BMDP Cream application related adverse events.
Informed consent through study completion, an average of 3 weeks
