About this study

Official title: Phase 1 Study to Evaluate the Safety, PK, PD, and Clinical Activity of STC-15, a METTL-3 Inhibitor, in Subjects With Advanced Malignancies

This Phase 1, multi-center, open-label, first-in-human study evaluates multiple ascending daily oral doses of STC-15 in Q3W treatment cycles in a 3+3 cohort design with dose levels determined by a modified Fibonacci algorithm. The study is designed to systematically assess safety and tolerability, pharmacokinetics, pharmacodynamics and clinical activity of STC-15 in adult subjects with advanced malignancies. Dose levels for further evaluation in expansion cohorts will be selected based on all available PK, pharmacodynamic, target engagement, efficacy, safety, and tolerability data including long-term safety data beyond dose limiting toxicities (DLTs). The study may be amended to evaluate STC-15 in combination with a Food and Drug Administration-approved standard of care treatment regimen, which could encompass targeted/chemotherapy, radiation therapy and/or immunotherapy with immune checkpoint blockers.

What is being measured

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

  1. Number of participants with adverse events

    To evaluate the incidence, severity, and duration of adverse events

    Measured: Screening through end of treatment, approximately 6 months

  2. Cmax (PK)

    To determine the Cmax concentration over a dosing interval, systemic clearance, volume of distribution at steady-state (Vss), and accumulation ratio from first dose to steady-state.

    Measured: Screening through Cycle 2 (each cycle is 21 days)

  3. Tmax (PK)

    To determine the time to Cmax (Tmax)

    Measured: Screening through Cycle 2 (each cycle is 21 days)

  4. Ctrough (PK)

    To determine observed trough serum concentration (Ctrough)

    Measured: Screening through end of treatment, approximately 6 months

  5. Terminal elimination half life (PK)

    To determine the terminal elimination half-life (t½)

    Measured: Screening through Cycle 2 (each cycle is 21 days)

  6. AUC (PK)

    To determine AUC in 1 dosing interval

    Measured: Screening through Cycle 2 (each cycle is 21 days)

  7. Average concentration (PK)

    To determine the average concentration over a dosing interval

    Measured: Screening through Cycle 2 (each cycle is 21 days)

  8. Systemic Clearance (PK)

    To determine the systemic clearance

    Measured: Screening through Cycle 2 (each cycle is 21 days)

  9. Volume of distribution at steady-state (PK)

    To determine the volume of distribution at steady-state (Vss)

    Measured: Screening through Cycle 2 (each cycle is 21 days)

  10. Accumulation ratio from first dose to steady-state (PK)

    To determine the accumulation ratio from first dose to steady-state

    Measured: Screening through end of treatment, approximately 6 months

Secondary outcomes (5)
  1. Efficacy as measured by RECIST 1.1 (DoR)

    Determine the duration of response (DoR)

    Measured: Screening through disease progression, approximately 6 months

  2. Efficacy as measured by RECIST 1.1 (PFS)

    Determine progression-free survival (PFS)/PFS assessed per immune-related response evaluation criteria (iPFS).

    Measured: Screening through disease progression, approximately 6 months

  3. Efficacy as measured by RECIST 1.1 (DCR)

    Determine the disease control rate (DCR)

    Measured: Screening through disease progression, approximately 6 months

  4. Efficacy as measured by RECIST 1.1 (ORR)

    Determine the objective response rate (ORR)

    Measured: Screening through disease progression, approximately 6 months

  5. Recommended Phase 2 Dose (RP2D)

    determine the RP2D for STC-15

    Measured: Screening through 90 days after the last dose of STC-15, approximately 9 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing STC-15 in people with Advanced Cancer and Advanced Solid Tumor, run by STORM Therapeutics LTD at 3 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 4 inclusion and 5 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 26 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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 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.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 adverse events (time frame: Screening through end of treatment, approximately 6 months). The study lists 10 primary outcomes in all. 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 26 Mar 2025.
