Filter by:The main purpose of this study is to evaluate the efficacy of mRNA 1647 vaccine in CMV-seronegative female participants and to evaluate the safety and reactogenicity of mRNA-1647 vaccine in all participants. The purpose of the Phase 3 extension sub study is to extend the observation period of the main study and to evaluate the longer-term immune persistence of mRNA-1647 vaccine administered to CMV-seronegative females who complete mRNA-1647-P301 main study and to assess for CMV seroconversion in CMV-seronegative participants who did not seroconvert during mRNA-1647-P301 main study. No interventional vaccine will be administered in the extension study.
This is a randomized clinical trial to assess whether a subject centered, self-collection of Dried blood spots (DBS) samples will improve compliance with the clinical recommendation of weekly Cytomegalovirus (CMV) testing of Hematopoietic cell transplantation (HCT) recipients who are at high risk for late CMV disease. In this study, mobile devices will be used to remind HCT survivors to perform CMV monitoring using finger-stick collected DBS testing in their home setting or to visit their doctor's office to perform the test. 150 allogeneic HCT recipients > /= 15 years of age will be randomized (2:1) to DBS monitoring or standard of care (per local institution) monitoring. Duration of study participation is anticipated to be within a range of 26 weeks to 43 weeks. The primary objective is to evaluate adherence to recommended CMV monitoring duration and interval during the first year after HCT upon enrollment using subject collected dried blood spot testing.
The relationship between cytomegalovirus infection and recurrence of hepatitis C in liver transplant recipients remains controversial. Although some studies (Teixeira et al., 2000; Singh et al., 2005)have not found an association between recurrence of hepatitis C and CMV infection, studies such as Rosen et al. show that 50% of patients with CMV infection suffered cirrhosis durig follow-up period, while between not-infected patients the rate was 11%. To clarify this question, a non-interventional study will be carried out in order to assess if CMV replication is a risk factor for graft dysfunction in liver transplant recipients.
