Overview
Biotherapies are biological (extracted from an organism or living tissue) or biotechnological drugs used in the treatment of multiple conditions, such as autoimmune inflammatory diseases, cancers, and hematologic diseases. In recent years, these biotherapies have notably emerged in the treatment of cancers and hematologic disorders. As such, most patients with cancers or hematologic diseases will likely receive a biotherapy as part of their care pathway. These biotherapies are associated with various side effects, including hypersensitivity or allergic reactions, which are often poorly characterized in clinical trials. These reactions manifest as symptoms without specific dermatologic or allergologic semiology (such as itching, erythema, shortness of breath, sometimes digestive issues, or discomfort, and in some cases, an anaphylactic reaction). Unlike other treatments, such as antibiotics and neuromuscular blockers, there are currently no guidelines on the concentrations to use in skin tests for biotherapies. We propose conducting prospective clinical research to scientifically establish the concentrations to be used when investigating hypersensitivity to a biotherapy, in line with best practice recommendations for drug skin testing.
Interventions
- Other Drug skin tests (investigating hypersensitivity to a biotherapy)
allergologic skin tests (prick tests and intradermal tests)
Primary outcome measures
- maximum usable concentration considered non-irritant [Time frame: Day 1]
Secondary outcome measures (2)
- possible occurrence of a delayed reaction at 48 hours post-testing [Time frame: Day 2]
- possible occurrence of a delayed reaction at one week post-testing [Time frame: Day 7]
Eligibility criteria

- Subjects covered by or having the rights to medical care assurance
- Written informed consent obtained from subject
- If applicable, treatment with corticosteroids and H1 antihistamines by systemic route (IV or oral) which may be discontinued at least one week before performing the tests (Inhaled corticosteroids are allowed).
Exclusion criteria
