Prediction of Rituximab Hypersensitivity and Desensitization Treatment
Study Overview
Status
Conditions
Intervention / Treatment
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Experimental group
Patients 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.

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.
