Informations principales
Titre : Etude multicentrique de phase II, randomisée, menée en ouvert visant à évaluer le bénéfice clinique d’un traitement post-opératoire associant radiothérapie + Nivolumab + Ipilimumab versus radiothérapie + Capécitabine chez des patientes atteintes d’un cancer du sein triple négatif et présentant une maladie résiduelle après chimiothérapie néoadjuvante

Spécialité : Seins, organes génitaux de la femme
Localisation : C50 - Tumeur maligne du sein
Informations complémentaires
Schéma : This trial is an open-label, randomised, multicentric, comparative, Phase II study aiming to evaluate the clinical benefit of a combined treatment associating radiotherapy + Nivolumab + Ipilimumab versus radiotherapy + Capecitabine (standard treatment) in early TNBC patients who have Residual cancer burden (RCB) III residual disease after neoadjuvant chemotherapy.

Following validation of eligibility criteria, patients will be randomised (1:1) to receive:

Arm A: Nivolumab (360 mg IV, every 3 weeks) for 8 doses and Ipilimumab (1 mg/kg, IV, every 6 weeks or every 2 doses of Nivolumab in case of dose delays) for 4 doses.
Arm B: Capecitabine (1000 mg/m2 twice a day, Bis In Die [BID]), 14 days on / 7 days off for 8 cycles.

In both arms, radiotherapy will be administered as per standard practice and has to be initiated one week before C1D1.

Phase : II

Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone curative therapy and other completely treated prior malignancy if no evidence of disease for ≥ 2 years.
Patient presents a contraindication to Nivolumab or Ipilimumab treatment as per respective SPC including known hypersensitivity to one of these study drugs or severe hypersensitivity reaction to any monoclonal antibody.
Patient presents a contraindication to Capecitabine treatment as per SPC including : 1) History of severe and unexpected reactions to fluoropyrimidine therapy, 2) Hypersensitivity to Capecitabine or to any of the excipients listed in SPC or fluorouracil, 3) Patients with known complete absence of dihydropyrimidine dehydrogenase activity, 4) Treatment with sorivudine or its chemically related analogues, such as brivudine, 5) any contraindication listed in respective SPC.
Patient has active autoimmune disease that has required systemic treatment in the past 3 months before C1D1 or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids at doses higher than 10 mg/d prednisone equivalents or immunosuppressive agents.
Patient requires the use of one of the following forbidden treatment during the study treatment period: any investigational anticancer therapy other than the protocol specified thérapies, any concurrent chemotherapy, immunotherapy, biologic for cancer treatment, other than the ones stated in the protocol. Concurrent use of hormones for non-cancer-related conditions (e.g., insulin for diabetes and hormone replacement therapy) is acceptable, major surger, live vaccines, immunosuppressive agents and immunosuppressive high doses of systemic corticosteroids i.e. doses >10 mg/d prednisone or equivalent, sorivudine or its chemically related analogues such as brivudine and any treatment contra-indicated as per Capecitabine SPC.
