Real-life efficacy and safety of cemiplimab in advanced cervical cancer from a nominal use program in Italy: The MITO 44 study.

BACKGROUND: cemiplimab is an immunoglobulin G4 monoclonal antibody targeting the programmed cell death-1 receptor. A nominal use program is available in Italy in advanced cervical cancer (CC) patients treated with platinum based chemotherapy based on the results of EMPOWER-Cervical 1/GOG-3016/ENGOTcx9 trial. This real-world, retrospective cohort, multicenter study aimed at describing clinical outcomes of patients with advanced CC treated with cemiplimab in Italy. METHODS: The primary objective of the study was to assess the feasibility and the replicability of the initial results in a real world setting of cemiplimab nominal use. The primary endpoint of our analysis was progression free survival (PFS). Secondary endpoints included overall response rate (ORR), overall survival (OS) and safety data. RESULTS: From March 2022 to December 2023, 135 patients were treated in 12 Multicenter Italian Trials in Ovarian cancer and gynecologic malignancies (MITO) Centers. Forty-two percent of patients had one or more comorbidities, hypertension being the most common (23.4%). Median PFS was 4.0 months (range 3.0-6.0) and median OS was 12.0 months (12.0- NR) with no differences according to PD-L1 status. Complete response (CR) or no evidence of disease (NED) were observed in 8.6%; partial response (PR) in 21.1%, stable disease (SD) in 14.8% and progression was recorded in 44.5% of patients. Most common drug related adverse events (AEs) were anemia (39.1%) and fatigue (27.8%). Immune related AEs occurred in 18.0%. CONCLUSIONS: This study confirms the feasibility and the replicability of the cemiplimab nominal use in advanced CC, in a real-world practice in Italy.

Prescribing pattern of anticoagulants in patients with cancer associated thrombosis: Results of a survey among MITO group and AIOM society.

INTRODUCTION: Low molecular weight heparin (LMWH) has been the backbone of the treatment of cancer associated thrombosis (CAT). Direct-acting oral anticoagulants (DOACs) have shown efficacy and safety not inferior to LMWH and guidelines included DOACs as an option for CAT treatment. Nevertheless, DOACs are still poorly prescribed in patients with cancer. The aim of this survey was to better understand prescription patterns of anticoagulants, in particular of DOACs, especially in gynecological cancers (GCs). METHODS: Our survey was made up of 21 questions, the last four questions addressed to medical doctors (MDs) involved in GCs. An invitation to complete the survey was sent by e-mail to 691 MITO (Multicentre Italian Trials in Ovarian cancer and gynaecologic malignancies) and 2093 AIOM (Associazione Italiana di Oncologia Medica) members. RESULTS: Overall, 113 MDs completed the questionnaire, 69 involved in GCs. Most respondents (46, 41%) were aged 30-40 years old, worked in public hospitals (59, 52.2%), were medical oncologists (86, 76.1%). LMWH was the preferred choice for the treatment of CAT (104, 92%). However, 89 respondents (78.8%) prescribed or asked to prescribe a DOAC for CAT. The major concern about DOACs was the difficulty in verifying the therapeutic effect and the absence of antidotes in case of bleeding (37.9%). In patients with GCs, DOACs were used with niraparib, olaparib, rucaparib and immune checkpoint inhibitors (ICIs) in less than 10 patients by 23%, 20%, 9% and 10.2% of respondents, respectively. CONCLUSION: The responders are aware of the Direct-acting oral anticoagulants option and would like to use them.
