About this study
Official title: Phase Ib/II Clinical Trial of Topical Verapamil Hydrochloride for Chronic Rhinosinusitis With Nasal Polyps
Verapamil is an L-type calcium channel blocker(CCB) which has been shown to reduce inflammation in a variety of tissues. Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by eosinophilic inflammation as well as P-gp overexpression. A previous trial of oral Verapamil showed preliminary efficacy for the treatment of CRSwNP. The goal of this study is to evaluate the safety and efficacy of intranasal Verapamil in CRSwNP. The study was initially approved as a Phase Ib/II, but only the Phase Ib portion was completed as part of this protocol.
Read the detailed description
CRSwNP is a prevalent disease associated with major direct and indirect costs. Acute and Chronic Rhinosinusitis are estimated to affect up to 16% of the US population. They account for approximately 11 million or 1% of all office visits per year in the US and are the most common cause for antibiotic prescriptions in the community. CRS alone impacts more than 30 million Americans resulting in $6.9 to $9.9 billion in annual healthcare expenditures and $12.8 billion in productivity costs. The subset of patients in Europe with CRSwNP has been estimated to be between 2 and 4.3% and is thought to be similar in the US. This population remains one of the most challenging subgroups of CRS to manage effectively.
Recent evidence has focused on the sinonasal epithelial cell as a primary driver of the local dysregulated immune response through secretion of type 2 helper T-cell(Th2) promoting cytokines. While these studies suggest that epithelial cells are capable of orchestrating a local immune response, the mechanisms responsible for regulating cytokine secretion are poorly understood and may be influenced by the efflux function of epithelial P-glycoprotein(P-gp). Studies by the investigator's group have demonstrated that P-gp is overexpressed in the mucosa of patients with Th2 skewed CRS endotypes including CRSwNP and is capable of regulating the secretion of Th2 polarizing cytokines. Together, these findings suggest that P-gp participates in the non-canonical regulation of cytokine secretion within CRSwNP and may thereby represent a druggable target.
The investigator's group therefore undertook a randomized, double-blind, placebo-controlled trial to test the efficacy of low dose oral Verapamil HCl, a known first generation P-gp inhibitor, for the treatment of CRSwNP. Our findings demonstrated significant efficacy in both of the primary and secondary endpoints with no significant side effects. However, a logistic regression analysis revealed two important relationships between baseline characteristics and efficacy. First, patients with elevated BMI had significantly lower improvements in the Sinonasal Outcome Test (SNOT-22) (p=0.01). The second is that patients with the highest total mucus P-gp levels experienced less benefit(p=0.01).
While Verapamil HCl has significant potential for the treatment of CRSwNP through P-gp inhibition, higher doses must be achieved to extend the effect to patients with elevated BMIs and the highest levels of P-gp expression. As increasing oral dosing could result in cardiac side effects, topical delivery represents a promising alternative. As exosome bound P-gp may be more stable and representative of disease state than total mucus P-gp concentration, exosomal P-gp demands further exploration as a novel biomarker of disease severity and drug response.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Verapamil Hydrochloride IntranasalDrug
Verapamil solution for injection, supplied in vials, will be utilized in a Neil Med Sinus Rinse of 240mL buffered normal saline.
| Study group | Role | What they receive |
|---|---|---|
| Phase Ib | Experimental | The phase Ib study will consist of an accelerated titration, intrapatient dose escalation cohort, with double-dose step design of Verapamil Hydrochloride. Intranasal BID for 1 week. Dose escalation will occur weekly as a doubling of the dose from 10-120mg Verapamil delivered in 240mL buffered normal saline. If a single, any course, dose-limiting toxicity (DLT) or second, any course, IT occurs, two additional patients will be recruited at that identified dose and Phase Ib will revert to a standard 3+3 design. If any patient un-enrolls while the dose escalation is still occurring, they will be replaced to maintain 3 patient cohorts. The maximal administered dose (MAD) will be considered that at which at least 2 DLTs or 4 ITs occur and the MTD will then be assigned to the immediate preceding dose.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Verapamil is an L-type calcium channel blocker(CCB) which has been shown to reduce inflammation in a variety of tissues. Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by eosinophilic inflammation as well as P-gp overexpression. A previous trial of oral Verapamil showed preliminary efficacy for the treatment of CRSwNP. The goal of this study is to evaluate the safety and efficacy of intranasal Verapamil in CRSwNP. The study was initially approved as a Phase Ib/II, but only the Phase Ib portion was completed as part of this protocol.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Verapamil Hydrochloride Intranasal in people with Sinusitis and Nasal Polyps, run by Benjamin Bleier at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 34 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 23 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 21 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Dose Limiting Toxicity (time frame: 1-8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03102190, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jul 2019.
