Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The purpose of this study is to determine the safety of IDOV-Immune, how well it is tolerated, and to identify the highest dose that can be safely given. Researchers will also study how the drug behaves in the body, how the immune system responds to it, and whether it shows any signs of shrinking tumors.
Participants will receive a single intravenous (IV) infusion of IDOV-Immune and will be closely monitored for side effects and any changes in their cancer.
This study is being conducted at multiple sites in the United States and Australia.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
IDOV-Immune is a genetically engineered vaccinia virus designed to selectively infect and destroy tumor cells while enhancing immune responses through the expression of immune-stimulating molecules. It has been further modified to improve tumor selectivity and minimize the risk of harming healthy cells.
Study Design:
The trial will follow a dose-escalation design to determine the maximum tolerated dose (MTD), the recommended Phase 2 dose (RP2D), and the overall safety and tolerability profile of IDOV-Immune. A Bayesian Optimal Interval (BOIN) design will guide dose-escalation decisions, based on observed dose-limiting toxicities (DLTs) during a 28-day observation period after the initial dose. The study will also assess preliminary signs of antitumor activity at each dose level.
IDOV-Immune will be administered as a single intravenous (IV) infusion on Day 1 of a 28-day treatment cycle. Participants will undergo frequent safety assessments, including physical exams, laboratory tests, imaging studies, and immune response monitoring. Pharmacokinetics (how the virus behaves in the body), pharmacodynamics (how the virus impacts immune and tumor-related biomarkers), and immunogenicity (the body's immune response to the virus) will also be evaluated.
Planned Enrollment and Cohorts:
The study is expected to enroll up to approximately 42 participants in the dose-escalation phase. If appropriate, additional participants may be enrolled in backfill cohorts at selected dose levels to further assess the safety, biomarkers , and preliminary efficacy in specific populations. Across all study parts, total enrollment could reach approximately 78 participants.
Study Objectives:
The primary objective is to assess the safety and tolerability of IDOV-Immune and to determine the RP2D for future studies. Secondary objectives include evaluating how the investigational product moves through and affects the body (pharmacokinetics and pharmacodynamics), as well as initial signs of tumor response, including objective response rate (ORR), disease control rate (DCR), and progression-free survival (PFS).
Rationale:
There remains a significant unmet need for effective therapies for patients with advanced solid tumors who have progressed on or are intolerant to standard treatments. Oncolytic viruses have the potential for destroying cancer cells and activating anti-tumor immune responses. IDOV-Immune's multi-pronged design - combining direct oncolysis, immune recruitment, and immune system activation - aims to maximize therapeutic potential while maintaining an acceptable safety profile.
Study Locations:
The study will be conducted at multiple clinical sites in the United States and Australia with expertise in early-phase oncology trials and oncolytic virus therapies.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
IDOV-Immune Dose Escalation Arm
Participants in this arm will receive a single intravenous (IV) infusion of IDOV-Immune, an investigational oncolytic vaccinia virus, on Day 1 of a 28-day treatment cycle. The study will follow a dose-escalation design, with each successive cohort receiving an increased dose based on safety data and observed dose-limiting toxicities (DLTs). Following dose escalation, expansion cohorts may be enrolled at selected dose levels to further assess safety and preliminary antitumor activity.
IDOV-Immune (oncolytic vaccinia virus)
IDOV-Immune is a genetically engineered oncolytic vaccinia virus designed to selectively infect and destroy tumor cells while stimulating the immune system. This study investigates IDOV-Immune as a single intravenous infusion in a first-in-human, Phase 1, dose-escalation trial in participants with advanced solid tumors. The dose will escalate based on safety data, with a goal of identifying the recommended Phase 2 dose (RP2D).
