What this trial studies

This is a noninterventional long-term follow-up study that tracks patients for five years after they received at least one dose of an RPx product in a Replimune-sponsored parent study. Eligible participants are rolled over after completing or withdrawing from the parent interventional study and will have no new therapies administered as part of this follow-up. Participants are contacted every three months and may have visits in person, by phone, or via video; suspected herpetic infections may prompt collection of swabs and other biological samples. The study focuses on detecting delayed adverse events such as new malignancies, neurologic or autoimmune disorders, hematologic problems, infections related to RPx, and herpetic-like infections.

Who should consider this trial

Good fit: Patients who previously received at least one dose of an RPx product in a Replimune-sponsored parent study and who can provide informed consent and comply with five years of follow-up are the intended participants.

Not a fit: People who never received an RPx product, cannot comply with long-term follow-up, or are seeking direct therapeutic benefit are unlikely to receive personal medical benefit from participation.

Why it matters

Potential benefit: If successful, this follow-up could identify late or rare adverse effects of RPx therapies and improve monitoring and safety guidance for future patients.

How similar studies have performed: Long-term safety monitoring is a standard practice after oncolytic and gene therapies and has previously identified delayed adverse events, but comprehensive RPx-specific long-term data are still emerging.
