About this study

This is a single-center prospective single arm study. The purpose of this study is to assess the usefulness of skin test as a diagnostic tool to predict the hypersensitivity to rituximab in Chinese population, evaluate the rate of hypersensitivity reactions (HSRs) after the application of active desensitization therapy in the case of a positive skin test result, and investigate the mechanism of HSRs to rituximab.

Read the detailed description

Patients with B-cell lymphomas who need the administration of rituximab are recruited. They undergo skin tests with rituximab before the first infusion of this medicine. In the case of a positive skin test result, the patient will receive the desensitization procedure; if the result of skin test is negative, the challenge test will be administered. Drug challenge test consists in administering the desired full dose of rituximab according to manufacturer instructions. Challenge is considered positive when it shows an objective HSR. The patient with a positive challenge test will receive the desensitization procedure; while the patient with a negative challenge test will be given standard rituximab infusion in the subsequent chemotherapies.

Peripheral blood will be drawn from all the subjects during their initial infusion of rituximab. If the patient shows hypersensitive symptoms, the blood will be drawn one hour after the onset of reaction; while if the patient has no HSR in the whole infusion process, the blood will be drawn at the end of infusion and used as negative control. Levels of tryptase, specific immunoglobulin E to rituximab, IL-6, IL-8, and TNF-α in the serum will be tested.

What participants receive

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

  • skin testDiagnostic test

    Also called desensitization for patients with positive skin test results

    For skin prick tests (SPT), rituximab solution of 1mg/ml was applied on the volar aspect of the forearm. For intradermal tests (IDT), 0.02 mL of a 1:100 dilution (0.1mg/ml) of full-strength solution (10mg/ml) was injected first. If the result was negative, a 1:10 dilution(1mg/ml)was then used.

    As to the desensitization protocol, three solutions with different concentrations are delivered in 12 consecutive steps, each step increasing the rate of drug administration by 2- to 2.5-fold. Solution 1 is a 100-fold dilution (0.01mg/ml) of the final target concentration, solution 2 is a 10-fold dilution (0.1mg/ml) of the final target concentration, and the concentration of solution 3 is the target concentration (1mg/ml). Each step takes 15 minutes until the target rate of 200ml/h is reached, and the final step is prolonged to complete the target dose. The whole procedure takes about 5.5 hours.

Study groupRoleWhat they receive
Experimental groupExperimentalPatients undergo diagnostic tests before the initial infusion of rituximab, including skin prick tests, intradermal tests, and challenge tests successively. If the skin test shows a positive result, the patient will receive desensitization procedure, and if the skin test is negative, the challenge test will be done, meaning normal infusion of rituximab according to manufacturer instructions. All the HSRs in the process of desensitization or normal infusion will be recorded. Peripheral blood will be drawn from all the subjects during their infusion to investigate the mechanism of HSRs to rituximab.

What is being measured

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

  1. Predictive value of skin test

    The sensitivity and specificity of skin test in the prediction of HSR to rituximab.

    Measured: From date of signing the informed consent until the end of induction chemotherapy, up to 32 weeks

Secondary outcomes (6)

    The rate of HSRs in all the enrolled subjects with the application of active desensitization therapy in the case of a positive skin test result.

    Measured: From date of signing the informed consent until the end of induction chemotherapy, up to 32 weeks

  2. Tryptase

    Level of serum tryptase

    Measured: From date of signing the informed consent until the end of induction chemotherapy, up to 32 weeks

  3. Specific immunoglobulin E to rituximab

    Level of serum specific immunoglobulin E to rituximab

    Measured: From date of signing the informed consent until the end of induction chemotherapy, up to 32 weeks

  4. IL-6

    Level of serum IL-6

    Measured: From date of signing the informed consent until the end of induction chemotherapy, up to 32 weeks

  5. IL-8

Questions about this trial

What is this clinical trial studying?

A study testing skin test in people with Drug Hypersensitivity Reaction, run by Peking Union Medical College Hospital at 1 site in China.

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 7 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: status not confirmed, as of the sponsor's last update on 30 Oct 2020. 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 China. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Predictive value of skin test (time frame: From date of signing the informed consent until the end of induction chemotherapy, up to 32 weeks). 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 30 Oct 2020.
