E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Anaemia with refractory cold agglutinin disease |
Anemia con crioagglutinemia refrattaria |
|
E.1.1.1 | Medical condition in easily understood language |
Type of red cell-destruction anaemia caused by cold autoantibodies. The refractory state is due to the lack of recovery from anaemia after first-line treatment. |
Forma di anemia da distruzione dei globuli rossi causata da autoanticorpi freddi. La refrattarietà è dovuta alla mancanza di risoluzione dell’anemia dopo trattamenti di prima linea. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to evaluate the achievement of transfusion independence after Bortezomib therapy or of a significant rise of hemoglobin concentration in patients with moderate to severe anemia related to CAD. |
L’obiettivo primario dello studio è valutare il raggiungimento dell’indipendenza da trasfusione dopo la terapia con Bortezomib o di un aumento significativo della concentrazione di emoglobina in pazienti con anemia da moderata a grave correlata a criogglutinemia (CAD, cold agglutinin disease). |
|
E.2.2 | Secondary objectives of the trial |
- Evaluation of Bortezomib therapy in terms of safety. - Evaluation of the duration of transfusion independence. - Evaluation of the effects of treatment on the underlying clonal B cell disorder. |
- Valutazione della terapia con Bortezomib in termini di sicurezza; - Valutazione della durata dell’indipendenza da trasfusione; - Valutazione degli effetti del trattamento sulle patologie correlate alle sottostanti linee cellulari B. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Patients with chronic cold agglutinin disorder requiring transfusion or with a hemoglobin concentration below 10g/L determined at least monthly during the two months before entering the trial; - Failure of at least one previous treatment attempt; - Hemoglobin level assessment; - Cold agglutinin (CA) titer at 4°C of 64 or higher; - Written informed consent. |
- Pazienti con patologia di crioagglutinemia che richieda una trasfusione o con una concentrazione di emoglobina al di sotto di 10g/L determinata almeno mensilmente durante i due mesi precedenti l’entrata nello studio; - Fallimento o almeno un precedente tentativo di trattamento; - Valutazione dei livelli di emoglobina; - Titolo della crioagglutinina a 4°C ≥ 64; - Consenso informato scritto. |
|
E.4 | Principal exclusion criteria |
- Presence of a concomitant lymphoproliferative disorder requiring specific treatment for reasons other than cold agglutinin related hemolytic anemia. - Preexisting peripheral neuropathy. - Known hypersensitivity to Bortezomib. - Non-cooperative behaviour or non-compliance. - Psychiatric diseases or conditions that might impair the ability to give informed consent. - Patients who are pregnant (women of childbearing potential must have a negative serum pregnancy test). Post-menopausal women must be amenorrhoic for at least 24 months to be considered of non-childbearing potential. Male and female patients must agree to employ an effective barrier method of birth control throughout the study and for up to 3 months following discontinuation of study drug |
- Presenza di una concomitante patologia linfoproliferativa, richiedente un trattamento specifico per ragioni diverse dall’anemia emolitica correlata alla crioagglutinemia; - Preesistente neuropatia periferica; - Conosciuta ipersensibilità al Bortezomib; - Comportamento non collaborativo o mancata aderenza alla terapia; - Disordini psichiatrici o condizioni che possano compromettere la capacità di esprimere il proprio consenso informato. - Donne in gravidanza. (Le donne potenzialmente fertili devono eseguire un test di gravidanza che risulti negativo). Le donne in menopausa non devono aver avuto il ciclo mestruale nei 24 mesi prima dell’inizio della terapia per essere considerate come non potenzialmente fertili. Uomini e donne devono essere d’accordo ad utilizzare una barriera contraccettiva efficace durante lo svolgimento dello studio e per 3 mesi dopo l’ultima somministrazione del farmaco sperimentale. |

Proporzione cumulata di pazienti liberi da trasfusione a 3 mesi dopo terapia con bortezomib o, nei pazienti non trasfusi, con un aumento di emoglobina > 2g paragonata al basale. |
