About this study

Official title: A Phase I/II, Open Label Study of Ad-RTS-hIL-12, an Adenovirus Vector Engineered to Express hIL-12, in Combination With an Oral Activator Ligand, in Subjects With Unresectable Stage III or IV Melanoma

This research study involves two investigational drugs, an Activator Ligand (INXN-1001) in combination with an Adenovirus Vector Engineered to Express hIL-12 (INXN-2001). IL-12 is a protein that may improve the body's natural response to disease by enhancing the ability of the immune system to kill tumor cells and may interfere with blood flow to the tumor.

The main purpose of this study is to evaluate the safety and tolerability of tumor injections of INXN-2001 given in combination with different doses of INXN-1001.

Read the detailed description

Single-arm, open label, Phase I/II dose escalation study of intratumoral injections INXN-2001 and oral INXN-1001 in subjects with unresectable Stage III or IV melanoma.

Four sequential dose escalation cohorts of INXN-1001 in combination with a fixed dose of INXN-2001 are planned. Subject enrollment and dose escalation will proceed according to a standard 3+3 design.

Approximately 15 additional subjects will be enrolled as an expansion cohort at a single dose level at or below the MTD.

  • Safety and tolerability will be assessed by the incidence and severity of adverse events.
  • The antitumor activity of study treatment will be assessed according to RECIST v1.1 guidelines. Additional assessment of anti-tumor activity will be explored based on total measurable tumor burden.
  • Immunological and biological markers of response will include examinations of tumor biopsy samples, cytokine levels, peripheral blood mononuclear cells (PBMC) and antibody response to INXN-2001.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment-Emergent Adverse Events

    Evaluation will be based on the incidence, intensity, and type of Adverse Events (AEs). Clinically significant changes in the subjects' physical examinations, vital signs, and ECG evaluations, and clinical manifestations relevant to abnormal laboratory values will be captured as AEs.

    Measured: From the signing of informed consent until 28 days after the last dose of study treatment, up to 28 weeks

Secondary outcomes (10)
  1. Area Under the Plasma Concentration-Time Curve (AUC) of INXN-1001 (Veledimex) in Cycle 1

    The area under the plasma concentration versus time curve from time 0 to the last measurable concentration (AUC0-t) for INXN-1001, calculated during the first treatment cycle.

    Measured: Samples were collected in Cycle 1 on Day 1 (pre-dose and 0.5, 1, 2, 4, and 6 hours post-dose), Day 2 (pre-dose), Day 7 (pre-dose and 1-2 and 4-6 hours post-dose), and Day 8 (24 hours after the Day 7 dose).

  2. Progression-Free Survival (PFS)

    Progression-Free Survival (PFS) was defined as the time in days from the first dose of study treatment to the first assessment of disease progression or death from any cause, whichever occurred first. Subjects who withdrew from the study were censored at the date of their last non-progressive disease assessment. The final analysis was performed using Kaplan-Meier methodology to determine the median PFS.

    Measured: From the first dose of study treatment for up to 1 year.

  3. Change From Baseline in Tumor IL-12 Messenger RNA (mRNA) Expression Change in IL-12 mRNA Expression Level (Arbitrary Units)

    Tumor biopsy samples were analyzed for IL-12 mRNA expression using quantitative real-time polymerase chain reaction (qRT-PCR).

    Expression levels were normalized to the housekeeping gene ACTB (β-actin) and quantified using the ΔΔCt method.

    For each participant, the median ΔΔCt-based fold-change from baseline to post-treatment was calculated.

    These individual participant-level medians were then averaged to derive the mean of medians (measure type) across all participants within each arm/group.

    The reported values therefore reflect the mean of medians in arbitrary units (AU), representing relative IL-12 mRNA expression normalized to ACTB- calculated as 2^(-ΔΔCt) fold-change relative to baseline

    Not all subjects in each arm contributed evaluable IL-12 mRNA expression data due to biopsy availability and RNA quality.

    Measured: Baseline (Screening) and at the Post-Treatment Safety Assessment (approximately 28 days after the end of Cycle 1).

  4. Maximum Plasma Concentration (Cmax) of INXN-1001 (Veledimex) in Cycle 1

    The maximum observed plasma concentration (Cmax) of INXN-1001 following oral administration, as determined from plasma sample analysis during the first treatment cycle

    Measured: Samples were collected in Cycle 1 on Day 1 (pre-dose and 0.5, 1, 2, 4, and 6 hours post-dose), Day 2 (pre-dose), Day 7 (pre-dose and 1-2 and 4-6 hours post-dose), and Day 8 (24 hours after the Day 7 dose)

  5. Change From Baseline in Peripheral Blood Cytotoxic T-Lymphocytes (CTLs)

    The percentage of Cytotoxic T-Lymphocytes (CTLs) within the CD8+ T-cell population was measured from serum samples by flow cytometry to assess changes in immune cell populations.

    Measured: Baseline (Screening) and at Cycle 2, Day 7

  6. Change From Baseline in Peripheral Blood Regulatory T-cells (Tregs)

    The percentage of Regulatory T-cells (Tregs) in peripheral blood lymphocytes was measured from serum samples by flow cytometry to assess changes in immune cell populations.

    Measured: Baseline (Screening) and at Cycle 2, Day 7.

  7. Change From Baseline in Tumor Interferon-gamma (IFN-γ) Messenger RNA (mRNA) Expression

    Tumor biopsy samples were analyzed for IFN-γ mRNA expression using quantitative real-time polymerase chain reaction (qRT-PCR). This measure reports the fold change in expression from baseline. Due to very low or undetectable baseline IFN-γ expression in many tumor biopsy samples, the fold change values calculated by qRT-PCR using the delta-delta Ct method may result in large numeric values. All values reported reflect fold change from baseline and were calculated per the qRT-PCR assay standard procedures

    Measured: Baseline (Screening) and at the Post-Treatment Safety Assessment (28 days after the end of Cycle 1).

  8. Ad-RTS-hIL-12 Vector Copy Numbers in Tumor Biopsy Samples

    To evaluate the presence of the viral vector in the tumor, biopsy samples were assessed for vector copy numbers using a quantitative polymerase chain reaction (qPCR) assay. The results are reported as the number of vector copies per 100 nanograms (ng) of deoxyribonucleic acid (DNA).

    Measured: Day 2 of Cycle 1, Day 2 of Cycle 2, and Day 2 of Cycle 3.

  9. Best Overall Response (BOR) by RECIST 1.1 Criteria

    Best Overall Response (BOR) was a pre-specified secondary endpoint assessed according to Response Evaluation Criteria In Solid Tumors (RECIST) v1.1. BOR is the best response recorded from the start of treatment until disease progression. Responses include Complete Response (CR), Partial Response (PR), Stable Disease (SD), and Progressive Disease (PD).

    Measured: From the first dose of study treatment for up to 1 year.

  10. Time to Maximum Plasma Concentration (Tmax) of INXN-1001 (Veledimex) in Cycle 1

    The time to reach the maximum observed plasma concentration (Tmax) of INXN-1001 following oral administration during the first treatment cycle.

    Measured: Samples were collected in Cycle 1 on Day 1 (pre-dose and 0.5, 1, 2, 4, and 6 hours post-dose), Day 2 (pre-dose), Day 7 (pre-dose and 1-2 and 4-6 hours post-dose), and Day 8 (24 hours after the Day 7 dose).

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing INXN-2001 and INXN-1001 in people with Melanoma, run by Alaunos Therapeutics at 9 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment-Emergent Adverse Events (time frame: From the signing of informed consent until 28 days after the last dose of study treatment, up to 28 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Oct 2025.
