A Study to Assess the Long-term Safety Outcomes in Patients Previously Treated With RP1, RP2, or RP3

Long-term outcomes include detection of delayed adverse event(s) for any new malignancy(ies), new incidence or exacerbation of a pre-existing neurologic disorder, rheumatologic or other autoimmune disorder, hematologic disorder, new incidence of infection related to RPx product and new incidence of herpetic-like infection. Patients with a suspected herpetic infection will be asked to provide a sample of the area of the suspected infection (using a swab), and also may be asked to provide additional biological samples (eg, a blood or urine sample to determine presence of RPx.) No study interventions will be administered in this observational study. Patients will be contacted by telephone every 3 months (Q3M) for 5 years from enrollment on this study. Participant visits may occur in person, over the phone, by video conference, or other technology.
