What is being measured

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

  1. Determination of Maximum Tolerated Dose (MTD) and Expansion Dose Level (EDL) [Dose Escalation Only]

    Identify the Dose-limiting Toxicities (DLTs) for each dose level tested and determine the MTD and EDL for ORM-5029

    Measured: DLT assessment period: At the end of Cycle 1 (each cycle is 21 or 28 days); Approximately 18 months for MTD and EDL

  2. Incidence of Adverse Events (AEs)

    Evaluate the safety and tolerability of ORM-5029 by identifying the treatment-emergent adverse events (TEAEs)

    Measured: Every cycle (each cycle is 21 or 28 days) until study discontinuation; Approximately 30 months

  3. Define the Objective Response Rate (ORR) of ORM-5029 based on Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 [Dose Expansion Only]

    ORR is defined as the percentage of subjects with Partial Response (PR) or Complete Response (CR)

    Measured: Approximately 30 months

  4. Define the Duration of Response (DOR) of ORM-5029 based on Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 [Dose Expansion Only]

    DOR is defined as the length of time from the date of the first documented response (PR or CR) until the date of first documented progression or date of death from any cause, whichever came first

    Measured: Approximately 30 months

Secondary outcomes (10)
  1. Assess pharmacokinetic (PK) parameters including area under the concentration versus time curve from time 0 hours to the last quantifiable concentration (AUC0-last) and from time 0 hours to infinity (AUC0-inf)

    Measured: Serial PK collections at on Days 1, 2, 4, 8 and 15 of Cycle 1 and Day 1 of Cycle 3 (Pre-dose and at multiple timepoints [up to 6 hours]; each cycle is 21 or 28 days)

  2. Assess maximum plasma and serum drug concentration (Cmax)

    Measured: Serial PK collections at on Days 1, 2, 4, 8 and 15 of Cycle 1 and Day 1 of Cycle 3 (Pre-dose and at multiple timepoints [up to 6 hours]; each cycle is 21 or 28 days)

  3. Define time to Cmax (Tmax)

    Measured: Serial PK collections at on Days 1, 2, 4, 8 and 15 of Cycle 1 and Day 1 of Cycle 3 (Pre-dose and at multiple timepoints [up to 6 hours]; each cycle is 21 or 28 days)

  4. Access pharmacokinetic (PK) parameters including terminal rate consent and terminal elimination half-life (t1/2)

    Measured: Serial PK collections at Baseline, Days 2, 4, 8 and 15 of Cycle 1 and Day 1 of Cycle 3 (Pre-dose and at multiple timepoints [up to 6 hours]; each cycle is 21 or 28 days)

  5. Define Clinical Benefit Rate (CBR) of ORM-5029 based on RECIST 1.1

    CBR is defined as CR + PR + stable disease (SD) up to 4 months

    Measured: Approximately 30 months

  6. Define Time to Response (TTR) of ORM-5029 based on RECIST 1.1

    TTR is defined as the length of time from baseline until the date of first documented response (PR or CR)

    Measured: Approximately 30 months

  7. Define Duration of Response (DOR) of ORM-5029 based on RECIST 1.1 [Dose Escalation Only]

    DOR is defined as the length of time from the date of the first documented response (PR or CR) until the date of first documented progression or date of death from any cause, whichever came first

    Measured: Approximately 30 months

  8. Assess Progression-free survival (PFS) of ORM-5029 based on RECIST 1.1

    PFS is defined as the length of time from baseline until the date of first documented progression or date of death from any cause, whichever came first

    Measured: Approximately 30 months

  9. Assess overall survival (OS)

    Measured: Following study discontinuation until withdrawal for any reason or death; Approximately 30 months

  10. Incidence of anti-drug antibody (ADA) against ORM-5029

    Measured: Sample collection at Baseline, Day 1 of every Cycle until study discontinuation (each cycle is 21 or 28 days); Approximately 30 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ORM-5029 in people with HER2-positive Breast Cancer and HER-2 Protein Overexpression, run by Orum Therapeutics USA, Inc. at 11 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 16 inclusion and 23 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: stopped early, as of the sponsor's last update on 4 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 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 was stopped early (reason given: Sponsor Decision). Results are not available in the source record.

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?

Determination of Maximum Tolerated Dose (MTD) and Expansion Dose Level (EDL) [Dose Escalation Only] (time frame: DLT assessment period: At the end of Cycle 1 (each cycle is 21 or 28 days); Approximately 18 months for MTD and EDL). The study lists 4 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 4 Jul 2025.
