About this study

Official title: Phase II, Multicenter, Randomized, Double Blind Study, With Subcutaneous Immunotherapy At Different Doses, in Parallel Groups and Placebo-Controlled, in Patients With Rhinoconjunctivitis ± Asthma Sensitized to Phleum Pratense

Based on EMA (European Medicines Agency) new guidelines on the clinical development of products for immunotherapy for the treatment of allergic diseases the aim of this study is to establish a dose-response relationship for clinical efficacy of Phleum pratense pollen extract subcutaneous vaccine.

Read the detailed description

In adherence to EMA guidelines, the Phase I Clinical trial was carried out using Phleum pratense extract in depot presentation using 3 different dose escalation scheme. The objective was to compare tolerance and safety of the three dose escalation scheme as well as to determine the maximum dose tolerated by the population.

Once the range of tolerated doses was established, and following the strict norms of the EMA, a Phase II dose response clinical trial was designed wherein the efficacy of subcutaneous immunotherapy in depot presentation could be compared in 5 different doses. One of these doses will be the MTD established by the population in the first study, another will be lower than this dose, and three will be greater than it. The dose escalation scheme to be tested was chosen based on the results of the aforementioned clinical trial. As dictated by EMA norms, a control placebo will be used.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Variation of the Concentration of Phleum Pratense Extract Needed to Produce a Positive Nasal Provocation Test From Baseline (V0) to Final Visit (FV).

    Variation of the concentration of Phleum pratense extract needed to produce a positive nasal provocation test from baseline (V0) to final visit (FV). The changes will be compared among groups (including the placebo group).

    Measured: Baseline (V0) and Final Visit (FV). The Final Visit will be conducted within 7 plus minus 2 days after the last dose is administered. The study will be carried out outside the pollination season of Phleum pratense.

Secondary outcomes (1)
  1. All Adverse Reactions and or Events Will be Recorded Both by the Patient and the Health Care Personnel Responsible for the Administration of the Subcutaneous Immunotherapy.

    All adverse reactions and/or events were recorded both by the patient and the health care personnel responsible for the administration of the subcutaneous immunotherapy. The incidence and intensity of adverse events was compared among the treatment groups.

    Measured: From baseline (V0) to final visit (VF). The Final Visit will be conducted within 7 plus minus 2 days after the last dose is administered. All AE should be monitored until they are satisfactorily resolved or stabilized after the final visit of the study

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Allergovac Depot in people with Allergic Rhinoconjunctivitis, run by Roxall Medicina España S.A at 10 sites in 2 countries.

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 11 inclusion and 14 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 29 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Portugal, Spain. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 29 Apr 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?

Variation of the Concentration of Phleum Pratense Extract Needed to Produce a Positive Nasal Provocation Test From Baseline (V0) to Final Visit (FV). (time frame: Baseline (V0) and Final Visit (FV). The Final Visit will be conducted within 7 plus minus 2 days after the last dose is administered. The study will be carried out outside the pollination season of Phleum pratense.). 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 29 Apr 2019.
