What this trial studies

This Phase I clinical trial evaluates the safety and tolerability of M1-c6v1, an oncolytic virus, administered intravenously to patients with locally advanced or metastatic solid tumors. The study is open-label and employs a dose-escalation approach to assess the biological distribution, immunogenicity, and preliminary anti-tumor effects of the treatment. Participants will receive multiple IV injections while their responses and any adverse effects will be closely monitored.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors who have not responded to standard therapies.

How similar studies have gone: While the use of oncolytic viruses is a novel approach, similar studies have shown promise in treating various cancers, indicating potential for success.
