What is being measured

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

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

    A DLT was defined as any AE, per National Cancer Institute - Common Terminology Criteria for Adverse Events, Version 5.0 (NCI-CTCAE v5.0), assessed by the Investigator or Sponsor at any dose, unrelated to underlying disease, prior/concomitant medication, or condition, occurring during the DLT observation period. DLTs included Grade more than equal to (≥) 3 thrombocytopenia with bleeding, excluding isolated Grade 4 lymphopenia without symptoms or Grade 4 neutropenia/thrombocytopenia less than (<) 7 days without signs. Other DLTs were Hy's Law hepatotoxicity without clear cause, vision changes (≥5-line Best Corrected Visual Acuity (BCVA) loss, BCVA <20/160, MD >9 decibel (dB), macular thickness >25 percentage (%)), severe eye disorders limiting self-care, ≥5-day drug interruption to prevent DLT.

    Measured: Cycle 1 (first 21 days after first study drug administration)

  2. Number of Participants With Treatment-emergent Adverse Events (TEAEs), Treatment Related TEAEs and Serious TEAEs

    An AE can be any unfavorable and unintended sign, symptom, or disease (new or exacerbated) temporally associated with the use of study intervention. For surgical or diagnostic procedures, the condition/illness leading to such a procedure is considered as the AE rather than the procedure itself. An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether considered related to the study intervention or not. An AE was considered as 'treatment emergent' if it occurred after the first drug administration of each period or if it was present prior to drug administration but exacerbated after the drug administration. TEAEs included both serious TEAEs and non-serious TEAEs. A SAE is defined as any untoward medical occurrence that, at any dose results in death, is life threatening, requires hospitalization, results in persistent disability. Treatment Related TEAEs are also reported.

    Measured: Up to 16 months

Secondary outcomes (9)
  1. Area Under the Plasma Concentration-Time Curve (AUC) From Time Zero to Time of Last Measurable Concentration (AUC0-tlast) of M1069

    The AUC from time zero (= dosing time) to the last sampling time (tlast) at which the concentration is at or above the lower limit of quantification. Calculated using the mixed log-linear trapezoidal rule (linear up, log down).

    Measured: Day 8 and 15 of Cycle 1 and Day 1 of Cycle 4 (each cycle is of 21 days)

  2. Area Under Plasma Concentration Time Curve From Time Zero to 24, Divided by Dose (AUC [0-24]/D) of M1069

    AUC [0-24]/D is the Area under plasma concentration time curve from time zero to 24 divided by dose (AUC [0-24]/D) of M1069. Calculated using the mixed log-linear trapezoidal rule (linear up, log down).

    Measured: Day 8 and 15 of Cycle 1 and Day 1 of Cycle 4 (each cycle is of 21 days)

  3. Maximum Observed Plasma Concentration (Cmax) of M1069

    Cmax is the maximum observed plasma concentration and was obtained directly from the concentration versus time curve.

    Measured: Day 8 and 15 of Cycle 1 and Day 1 of Cycle 4 (each cycle is of 21 days)

  4. Maximum Observed Plasma (Peak) Drug Concentration, by Dose (Cmax/D)

    Cmax/D is the maximum observed plasma concentration by dose. Cmax was obtained directly from the concentration versus time curve, divided by Dose of M1069.

    Measured: Day 8 and 15 of Cycle 1 and Day 1 of Cycle 4 (each cycle is of 21 days)

  5. Time to Reach Peak or Maximum Observed Concentration or Response Following Drug Administration (Tmax)

    The time to reach the maximum observed plasma concentration (Tmax) was obtained directly from the concentration versus time curve.

    Measured: Day 8 and 15 of Cycle 1 and Day 1 of Cycle 4 (each cycle is of 21 days)

  6. Objective Response (OR) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1), as Assessed by Investigator

    OR is defined as a best overall response (BOR) of complete response (CR) or partial response (PR). CR: Disappearance of all evidence of target and non-target lesions. PR: At least 30% reduction from baseline in the sum of the longest diameter (SLD) of all target lesions. Number of participants with BOR of CR or PR was reported.

    Measured: Time from first observation of response (CR or PR) up to planned assessment at 17.3 months

  7. Duration of Response (DoR)

    DoR is the time from when the complete response (CR) or partial response (PR) (whichever is first) criteria are first met until disease progression (PD) or death due to any cause within the period of 2 scheduled tumor assessments after the last tumor assessment, whichever occurs first. PD is defined as at least a 20 percent (%) increase in the sum of the longest diameter (SLD), taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions.

    Measured: Time from first observation of response (CR or PR) up to planned assessment at 17.3 months

  8. Progression-free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1), as Assessed by Investigator

    PFS is defined as the time (in months) from first administration of study intervention to the date of the first documentation of progression disease (PD) or death due to any cause within the period of 2 scheduled tumor assessments after the last tumor assessment, whichever occurs first. PD is defined as at least a 20 percent (%) increase in the sum of the longest diameter (SLD), taking as reference the smallest SLD recorded from baseline or the appearance of 1 or more new lesions. PFS was to be estimated using Kaplan-Meier (KM) plots.

    Measured: Time from first administration of study intervention to the date of the first documentation of progression disease (PD) or death due to any cause within, whichever occurs first, assessed up to maximum of 17.3 months

  9. Change From Baseline in Corrected QT (QTc) Interval

    A 12-lead ECG was recorded with the participant in a supine position after a rest of at least 10 minutes using an ECG machine. Change from baseline in QTc interval was reported. In the Timeframe the "C" refers to Cycle, "D" refers to Day and "h" refers to the hours.

    Measured: Cycle (C)1Day (D)1: 1h, 2h, 4h, 6h, 8h post-dose; C1D8: 15min predose, 1h, 2h, 4h, 6h, 8h post-dose; C1D15: predose; C2D1: predose, 2h post-dose; C4D1, C6D1, C10D1, C12D1, C14D1, C18D1(each cycle is of 21 days)

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 8 inclusion and 9 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 22 Apr 2026. 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, Canada. 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?

Yes. Results are posted in the registry (first posted 22 Apr 2026). 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 Dose-Limiting Toxicities (DLTs) (time frame: Cycle 1 (first 21 days after first study drug administration)). The study lists 2 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 22 Apr 2026.
