A Phase 2 interventional study of Research Grade RG-RV in Asthma, Allergic Rhinitis and Cat Allergy, sponsored by The University of Texas Medical Branch, Galveston. Recruiting at 1 site in United States. Open to participants aged 18 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-01-28.
Sponsored by The University of Texas Medical Branch, Galveston · Phase 2, Interventional, and Basic science
This is a mechanistic, controlled, open-label, single-site study to evaluate the effects of RG-RV16 inoculation on airway mucosal gene expression and airway remodeling in 25 healthy controls (HC), in 25 allergic rhinitis subjects (AR) with cat dander allergy, and in 25 allergic asthmatic subjects (AA) with cat dander allergy. Three groups (HC, AR, and AA) will undergo screening to establish clinical history, will undergo pulmonary function testing (spirometry), and will have blood drawn for clinical characterization (IgE, , ImmunoCAP, CBC and differential), and for assessing the presence of existing neutralizing antibody against RV16. Only those who meet criteria will be permitted to continue into the interventional and run-out phases of the study.
4,841 studies on the registry are indexed under Asthma; 600 are open to participants now.
This study's planned enrollment of 75 is close to the median of 78 across 3,341 interventional studies indexed under Asthma.

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.
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.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.
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.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
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.

Started Apr 2023 (actual). Primary completion is estimated for May 2027, 48 months after the start.
Of 61 non-industry phase 2 interventional studies under Asthma, half reached primary completion within 46 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 62. This study's planned 48 months is close to that.
Counting every sponsor, half of 198 studies reached it within 20 months; a quarter within 12 and three quarters within 41.
