About this study

Official title: A Prospective, Randomized, Double-Blind, Placebo-Controlled, Single-Center Study of the Intradermal Injection of rHuPH20 or Placebo in Subjects With Nickel Allergic Contact Dermatitis

The purpose of this study is to compare the effect and safety of rHuPH20 or placebo for the prevention and treatment of skin allergic reaction to nickel. The study drug and placebo will be administered by intradermal injection.

Read the detailed description

This study will involve 2 regimens which will run in parallel. Each participant's upper back will be divided into 2 equal spaces for Regimen 1 and 2. Each of the 4 treatment sites in each space will be independently randomized to placebo or rHuPH20 treatment in a 1:1 ratio. Thus, each participant will serve as their own control. Regimen 1 will evaluate the treatment of cutaneous reactions to nickel and Regimen 2 will evaluate the prevention as well as the treatment of cutaneous reactions to nickel. At screening, the nickel sulfate concentration (1%, 2.5%, or 5%) applied to the skin of the upper back with a patch, that will cause no more than a ++ reaction according to the scale of the International Contact Dermatitis Research Group (ICDRG) will be determined. This concentration will be used to elicit cutaneous reactions during the study period.

Study groups in NCT00928447
Study groupRoleWhat they receive
rHuPH20ExperimentalParticipant's upper back will be divided into 2 equal spaces and will receive Regimen 1 and 2 in 4 spaces respectively. In Regimen 1, a single row of 4 patches, each with the nickel sulfate concentration (NSC) (1, 2.5, or 5%) determined at screening, will be applied to the upper space at Day 1. After 48 hours, the patches will be removed and the reactions will be graded on the ICDRG scale. An ID injection containing rHuPH20 (3,000 Units [U]) will be administered once daily (QD) for 5 days at the center of each area of reaction. In Regimen 2, a single row of 4 sites in the lower space will be injected intradermally with drug rHuPH20 (3,000 U) at Day 1. Ten minutes after the injections, patches with the NSC (1, 2.5, or 5%) determined at screening will be applied to the injection sites. After 48 hours, the patches will be removed and the reactions will be graded on the ICDRG scale. As during pretreatment, an ID injection containing rHuPH20 will be then administered QD for 5 days.

What is being measured

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

  1. Number of Participants With Positive Reaction Scores Based Upon ICDRG Scoring Scale: Regimen 1

    Cutaneous reactions at the patch test sites were scored according to the ICDRG scoring scale as Grade 0 (-)= Negative reaction, Grade 1/2 (?)= Doubtful reaction; faint macular erythema only, Grade 1 (1+)= Weak (nonvesicular) positive reaction; erythema, infiltration, papules, vesicles, Grade 2 (2+): Strong (vesicular) positive reaction; erythema, infiltration, papules, vesicles, Grade 3 (3+): Extreme positive reaction; bullous reaction Grade NA (IR): Irritant reaction of different types. Participants with positive reaction scores (>= Grade 1) have been reported in this outcome measure.

    Measured: Day 3 (48 hours post-dose after the patch removal for Regimen 1) up to Day 14

  2. Number of Participants With Positive Reaction Scores Based Upon ICDRG Scoring Scale: Regimen 2

    Cutaneous reactions at the patch test sites were scored according to the ICDRG scoring scale as Grade 0 (-)= Negative reaction, Grade 1/2 (?)= Doubtful reaction; faint macular erythema only, Grade 1 (1+)= Weak (nonvesicular) positive reaction; erythema, infiltration, papules, vesicles, Grade 2 (2+): Strong (vesicular) positive reaction; erythema, infiltration, papules, vesicles, Grade 3 (3+): Extreme positive reaction; bullous reaction Grade NA (IR): Irritant reaction of different types. Participants with positive reaction scores (>= Grade 1) have been reported in this outcome measure.

    Measured: Day 3 (48 hours post-dose after the patch removal for Regimen 2) up to Day 14

Secondary outcomes (3)
  1. Percentage of Participants With a >=1 Grade Change in ICDRG Score in at Least One Patch Region After Treatment With rHuPH20 or Placebo: Regimen 1

    Cutaneous reactions at the patch test sites were scored according to the ICDRG scoring scale as Grade 0 (-)= Negative reaction, Grade 1/2 (?)= Doubtful reaction; faint macular erythema only, Grade 1 (1+)= Weak (nonvesicular) positive reaction; erythema, infiltration, papules, vesicles, Grade 2 (2+): Strong (vesicular) positive reaction; erythema, infiltration, papules, vesicles, Grade 3 (3+): Extreme positive reaction; bullous reaction Grade NA (IR): Irritant reaction of different types.

    Measured: Day 3 (48 hours post-dose after the patch removal for Regimen 1)

  2. Percentage of Participants With a >=1 Grade Change in ICDRG Score in at Least One Patch Region After Treatment With rHuPH20 or Placebo: Regimen 2

    Cutaneous reactions at the patch test sites were scored according to the ICDRG scoring scale as Grade 0 (-)= Negative reaction, Grade 1/2 (?)= Doubtful reaction; faint macular erythema only, Grade 1 (1+)= Weak (nonvesicular) positive reaction; erythema, infiltration, papules, vesicles, Grade 2 (2+): Strong (vesicular) positive reaction; erythema, infiltration, papules, vesicles, Grade 3 (3+): Extreme positive reaction; bullous reaction Grade NA (IR): Irritant reaction of different types.

    Measured: Day 3 (48 hours post-dose after the patch removal for Regimen 2)

  3. Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

    TEAEs were defined as adverse events (AEs) with an onset during or following administration of the first dose of study drug. AEs were defined as any untoward medical occurrence in a participant administered study drug and that did not necessarily have a causal relationship with the study drug. SAEs were defined as any AE that, in the view of either the Investigator or Sponsor, resulted in any of the following outcomes as fatal, life-threatening, required in-participant hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, a congenital anomaly/birth defect, an important medical event. Adverse Events were only monitored/assessed on the whole participant level irrespective of different treatment regimen. A summary of all SAEs and Other AEs (nonserious) regardless of causality is located in 'Reported Adverse Events' Section.

    Measured: Baseline up to Day 14

Who may be eligible to take part?

The sponsor lists 8 inclusion and 10 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 17 Dec 2021. 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. 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 17 Dec 2021). 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 Positive Reaction Scores Based Upon ICDRG Scoring Scale: Regimen 1 (time frame: Day 3 (48 hours post-dose after the patch removal for Regimen 1) up to Day 14). The study lists 2 primary outcomes in all. 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.
