Trial summary

Recently, interest has increased in sublingual immunotherapy (SLIT) for treating allergic rhinitis. It is often suggested that polysensitized patients might not benefit from specific immunotherapy as much as monosensitized patients, although further research on this subject is needed.

About this study

Official title: Efficacy of Sublingual Immunotherapy With House Dust Mite Extract in Poly-allergen-sensitized Allergic Rhinitis Patients

Recently, interest has increased in sublingual immunotherapy (SLIT) for treating allergic rhinitis. It is often suggested that polysensitized patients might not benefit from specific immunotherapy as much as monosensitized patients, although further research on this subject is needed. This study compared the efficacy of SLIT with standardized house dust mite extract in mono- and polysensitized allergic rhinitis patients.

Patients who were sensitized to house dust mites and treated with SLIT for house dust mites for at least 1 year between November 2007 and March 2010 were included. The mono-allergen sensitized group (Mgr) was defined as the patients who were sensitized to Dermatophagoides pteronyssinus (Dp) or D. farinae (Df; n = 70). The poly-allergen sensitized group (Pgr) was defined as the patients who were simultaneously sensitized to house dust mites and other allergens (n = 64). A standardized extract of house dust mites was used for immunotherapy. Anti-allergic medication and the total nasal symptom score (TNSS), including rhinorrhea, sneezing, nasal obstruction, and itchy nose, were evaluated before and 1 year after SLIT.

This study enrolled 134 patients. The TNSS improved significantly after SLIT in both groups, while the change in the TNSS did not differ significantly between the groups. The anti-allergic medication scores also decreased significantly in both groups, but there was no significant difference between the groups.

In polysensitized allergic rhinitis patients, SLIT for Dp/Df gave comparable improvements in both nasal symptoms and rescue medication scores to those in monosensitized patients, regardless of other positive allergens. SLIT for Dp/Df might be considered in polysensitized allergic rhinitis patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pangramin®Drug

    During a 4-week increasing-dose phase, the patients increased the daily dose from 1 to 5 drops of 1.6 STU/mL solution from day 1 to 10, 1 to 5 drops of 8 STU/mL solution from day 11 to 15, 1 to 5 drops of 40 STU/mL solution from day 16 to 20, 1 to 5 drops of 200 STU/mL solution from day 21 to 25, and 1 to 5 drops of 1000 STU/mL solution from day 26 to 30. After reaching the maintenance dose, 5 drops of 1000 STU/mL solution, the patients took the allergen three times per week during the maintenance phase.

Questions about this trial

What is this clinical trial studying?

A study testing Pangramin® in people with Allergic Rhinitis, run by Seoul National University Hospital at 1 site in South Korea.

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 2 inclusion and 2 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: finished, as of the sponsor's last update on 24 Nov 2010. 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 South Korea. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

total nasal symptom score (TNSS) and anti-allergic medication score (AMS) (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 24 Nov 2010.
