Study summary

This Phase 1, open-label study will evaluate VT-101, an investigational small-molecule therapy, in adult women with advanced, recurrent, or relapsed epithelial ovarian cancer. The primary objectives are to assess the safety, tolerability, and pharmacokinetic profile of VT-101 and to identify a recommended dose for further study. Secondary and exploratory objectives include evaluation of preliminary antitumor activity and characterization of treatment-related effects in participants with limited standard treatment options.

Read the detailed description

This is a Phase 1, open-label, dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of VT-101 in adult women with advanced, recurrent, or relapsed epithelial ovarian cancer. Eligible participants must have disease that has progressed following prior therapy or have exhausted, refused, become intolerant of, or are otherwise ineligible for available standard treatment options.

Participants will receive VT-101 administered according to a dose-escalation design to evaluate the safety profile of escalating dose levels and to identify an appropriate dose and schedule for further clinical development. Safety assessments will include the evaluation of adverse events, serious adverse events, dose-limiting toxicities, clinical laboratory parameters, physical examinations, vital signs, and other protocol-specified assessments.

Pharmacokinetic analyses will be performed to characterize the absorption, distribution, metabolism, and elimination of VT-101. Antitumor activity will be assessed using protocol-defined efficacy endpoints, including tumor response and disease control measures. Exploratory analyses may evaluate biomarkers and other factors associated with treatment response and clinical outcomes.

The information generated from this study will support determination of the safety profile, pharmacokinetic characteristics, and recommended dose of VT-101 for subsequent clinical investigation in patients with advanced epithelial ovarian cancer.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

  • Experimental
    VT-101 Dose Escalation and Expansion

    Participants will receive VT-101 by intraperitoneal administration once weekly for four doses on Days 1, 8, 15, and 22. During Phase I, doses will be escalated using a standard 3+3 design, starting at 1 × 10⁸ microvesicles (MVs) per dose, followed by 1 × 10⁹ and 1 × 10¹⁰ MVs per dose. Once the maximum tolerated dose (MTD) is determined, enrollment at the MTD will be expanded to include 10 patients in the efficacy evaluation. Patients treated at the MTD during Phase I will count toward this total.

    Drug: VT-101

Interventions

  • DrugVT-101

    VT-101 is an investigational therapy consisting of autologous M1 macrophage-derived vesicles generated through membrane fragmentation. VT-101 is administered intraperitoneally via an implanted port over approximately 45 minutes, once weekly on Days 1, 8, 15, and 22, for four doses. Phase I dose escalation follows a standard 3+3 design, beginning at 1 × 10⁸ vesicles per dose and escalating to 1 × 10⁹ and 1 × 10¹⁰ vesicles per dose. Each participant receives the same dose level. After the maximum tolerated dose is established, an expansion cohort will evaluate preliminary efficacy at that dose.

06

What researchers measure

Primary outcomes

  1. Number of Participants With Dose-Limiting Toxicities (DLTs)

    Number of participants experiencing dose-limiting toxicities (DLTs) during Phase I dose escalation. The maximum tolerated dose (MTD) will be defined as the highest dose level at which no more than 1 of 6 participants experiences a DLT.

    Time frame: From the first dose through 14 days after the Day 22 dose. This reflects the Phase I primary endpoint and the protocol's specified toxicity-monitoring window.

  2. Overall Response Rate (ORR)

    Proportion of participants achieving a complete response (CR) or partial response (PR), assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Participants who do not meet the criteria for an objective response will be considered non-responders.

    Time frame: Beginning 1 month after the fourth dose (±7 days), then every 8 weeks for the first 12 months and every 12 weeks thereafter until disease progression or the end of study.

Secondary outcomes

  1. Proportion of Participants With a ≥50% Reduction in CA-125

    Proportion of participants who achieve at least a 50% reduction in CA-125 levels relative to baseline.

    Time frame: From baseline to after 4 doses of VT-101 (Days 1, 8, 15, and 22).

  2. Progression-Free Survival (PFS)

    Time from treatment initiation to the first documented disease progression or death from any cause, whichever occurs first. Participants without documented progression or death will be censored at their last radiographic assessment for progression.

    Time frame: From treatment initiation until disease progression or death, with tumor imaging beginning 1 month after the fourth dose and then every 8 weeks for the first 12 months and every 12 weeks thereafter.
