E.2 Objective of the trial |
E.2.1 | Main objective of the trial | To describe and investigate safety and tolerability of the intradermal delivery of two fractional doses of 20 μg mRNA-1273 in patients with Fibrodysplasia Ossificans Progressiva. | |
E.2.2 | Secondary objectives of the trial | To compare the immunogenicity of patients with FOP after intradermal delivery of two fractional doses of 20 μg mRNA-1273 with that of two doses of 20 μg mRNA-1273 vaccine through intramuscular delivery and intradermal delivery on Day 43, as previously investigated in LUMC cohort of healthy adults | |
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria | In order to be eligible to participate in this study, a subject must meet all of the following criteria: •Fibrodysplasia ossificans progressiva as determined by confirmation of any causative genetic mutation in the ACVR1 gene as previously described (1). •18 years or older •Participants who are willing and able to comply with all scheduled visits, vaccination tests and other study procedure •Capable of giving personal signed consent as described in appendix 1, which includes compliance with the requirements and restrictions listed in the ICD and this protocol •Females only: female volunteers of childbearing potential (i.e. have a uterus and are neither surgically sterilised nor post-menopausal) must not be pregnant or breastfeeding. They should agree to use adequate contraception at least up to four weeks following the final dose of mRNA-1273 vaccine. | |
E.4 | Principal exclusion criteria | A potential subject who meets any of the following criteria will be excluded from participation in this study: •History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (eg, anaphylaxis) to any component of the study intervention(s). •Receipt of medications intended to prevent SARS-CoV-2 infection. •Current clinical complaints consistent with SARS-CoV-2 infection (three or more of the following complaints: headache, loss of smell, sore throat, hoarseness, cough, chest pain, shortness of breath, fatigue, diarrhea, fever). •SARS-CoV-2 vaccination 6 months prior to participation. •Immunosuppressed individuals with known or suspected immunodeficiency, as determined by history. •Individuals with a history of autoimmune disease or an active autoimmune disease requiring therapeutic intervention. •Women who are pregnant or breastfeeding. •Planned pregnancy within four weeks after the final injection. •SARS-CoV-2 PCR-positive EMA approved lateral flow test at the screening before receipt of fist vaccine dose •Receipt of any other non-study vaccine within 28 days, before first study dose. •Anticipated receipt of any other non-study vaccine within 28 days, after last study dose administration. | |
E.5 End points |
E.5.1 | Primary end point(s) | •Nature, frequency and severity of local reactions.
