Recruiting at 4 sites in Australia. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2024-11-12.

Study summary

To assess the safety and efficacy of one (single) application of Betamethasone Dipropionate Nasal Cream (BMDP CREAM) onto the sinus mucosa.

Read the 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.

Inclusion criteria

  • Adult patients with a clinically confirmed diagnosis of CRS by an otolaryngologist (ENT) undergoing maximal medical therapy as part of their standard of care.
  • Having undergone functional endoscopic sinus surgery (FESS) at least 6 months prior to enrolment.
  • 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 of ≤ 39 at the screening visit.
  • Individuals of must use adequate methods and not plan to get pregnant during the study.
  • : Willingness to give written informed consent and willingness to participate in and comply with the study.
  • Age ≥18 but \<80 years.

Exclusion criteria

Exclusion Criteria:

  • Subjects with known or 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 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 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.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Study arms

  • Experimental
    Betamethasone Dipropionate Nasal Cream 0.0644% Treatment

    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).

Interventions

  • DrugBetamethasone Dipropionate Nasal Cream 0.0644%

    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).

  • DevicePre-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 researchers measure

Primary outcomes

  1. Change in 4-Cardinal Symptom score (4CSS) Baseline to Week 3.

    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.

    Time frame: Baseline through study completion, an average of 4 weeks

  2. Change in SNOT-22 Baseline to Week 3.

    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.

    Time frame: Baseline through study completion, an average of 4 weeks

Secondary outcomes

  1. Safety of one application of BMDP Cream onto the sinus mucosa.

    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.

    Time frame: Informed consent through study completion, an average of 3 weeks
