AAV Gene Therapy Screening/Observational Protocol (ECLIPSE)

Hemophilia BBlood Coagulation Disorders3 more

Freeline is developing adeno-associated virus (AAV) vector based gene therapies for a number of diseases and is actively advancing a programme in Haemophilia B (HB). This study aims to collect prospective data to characterise bleeding events and Factor IX (FIX) concentrate consumption in HB patients that can be used as baseline for participants who elect to participate in a subsequent Freeline gene therapy study. The study will also screen participants for antibodies to a novel AAV vector to assess their suitability for inclusion in a Freeline gene therapy treatment study.

Frequency of COVID-19 Antibodies in Patients With Hereditary Hematological Diseases

Thalassemia MajorCovid19

In Italy there are about 5000 patients with dependent transfusion thalassemia (source Italian Thalassemia and Hemoglobinopathies - SITE) and a smaller number, currently not definable, of patients with sickle cell anemia in chronic transfusion. A recent study in the Lombardy region identified the positivity of anti-Covid-19 antibodies in 4.5-7% of asymptomatic donors (Valenti L et al). As already known, a preliminary study conducted in Italy (Motta I et al, Hussain FA et al, Taher A et al) reported only 11 cases of symptomatic infection all with benign evolution. Currently there are 15 reported cases (12 thalassemias and 3 sickle cell anemias). 75% of the cases have been identified in Lombardy. Our hypothesis is that in a percentage of polytransfused patients a transmission of the virus may have developed that stimulated the production of protective antibodies. This could be an explanation of the low contagiousness and severity of the infection in polytransfused patients. Currently no data are available for this purpose. This study will be conducted in collaboration with the Microbiology Unit and involves the determination of SARS-CoV-2 antibodies (anti-s1 and s2) by CLIA method with a high sensitivity (94.7%) and specificity (98.5%).

Evaluation of the Reasons and Consequences of Bleeding in Late Teens and Early Adulthood Patients...

Hematologic DiseaseBlood Coagulation Disorders

Understanding how often the bleeding events occur in the subjects who voluntarily decide to switch from prophylaxis to on-demand and in those subjects who remain on prophylaxis. Also look into the consequences of switching treatment in QoL (quality of life), development of target joints, activity level and reasons that might influence the desire to switch.
