Study summary

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patient treated with one of the biotherapies under study (Atezolizumab 1200 mg, Nivolumab 480 mg, Obinutuzumab 100 mg, Durvalumab 1500 mg, Pembrolizumab 200 mg, Daratumumab 1800 mg, Cemiplimab 3500 mg) and who has received at least two injections of the biotherapy without suspected allergic side effects.
  • Subjects covered by or having the rights to medical care assurance
  • Written obtained from subject
  • If applicable, treatment with 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

Exclusion Criteria:

  • Presence of local or diffuse dermatological lesions (e.g., psoriasis, eczema, ...) that could interfere with the interpretation of skin tests.
  • Poor understanding of the French language
  • Pregnancy, breastfeeding
  • Persons in detention by judicial or administrative decision
  • Person admitted to a health or social establishment for purposes other than research
  • Person subject to a legal protection measure
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. maximum usable concentration considered non-irritant

    For each biotherapy studied, the maximum usable concentration considered non-irritant is defined as the maximum concentration that does not produce a skin reaction in at least 9 out of 10 patients (90% specificity) during skin testing.

    Time frame: Day 1

Secondary outcomes

  1. possible occurrence of a delayed reaction at 48 hours post-testing

    delayed reaction is considered if, at the intradermal injection sites, a skin reaction occurs 48 hours after injection, or if a systemic reaction occurs following biotherapy administration.

    Time frame: Day 2

  2. possible occurrence of a delayed reaction at one week post-testing

    delayed reaction is considered if, at the intradermal injection sites, a skin reaction occurs 1 week after injection

    Time frame: Day 7

Individual participant data

Plan to share: Yes — Data will be shared upon reasonable request. Only de-identified data will be shared. Any data collected during the study may be shared. The protocol will be shared initially. Other documents may be shared at a later date upon request (e.g., the CRF to allow a collaborator to select the data they wish to access). The recipients of the data will be researchers. The data will be available for any purpose deemed relevant by the study investigator, based on a protocol provided by the requester, after verification of the obtaining of regulatory approvals, including the favorable opinion of an ethics committee.

Supporting information: Study protocol

Time frame: The data will be shared after signing a negotiated data transfer agreement ( data access agreement), for the duration specified in the agreement.

Access criteria: The data will be made available via secure transfer (sharing platform approved by the university hospital: BlueFiles or Oodrive).

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 18, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
