About this study

Official title: A Modular Phase I/II, Open-Label, Multi-Centre Study to Assess the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of AZD0466 Monotherapy or in Combination in Patients With Advanced Haematological Malignancies

The purpose of the study is to the evaluate safety, tolerability, pharmacokinetics (PK), and efficacy of AZD0466 as monotherapy in partciapants with advanced haematological malignancies and also to assess drug-drug interaction (DDI) potential between AZD0466 and the azole antifungal voriconazole.

Read the detailed description

The study consists of 2 individual modules as: Module 1 (AZD0466 monotherapy), and Module 2 (DDI study of AZD0466 with voriconazole).

Eligible participants will be assigned to study treatments across Modules 1 and 2.

  1. Module 1: AZD0466 monotherapy will include 2 parts- Part A dose escalation cohorts and Part B dose expansion cohorts. Initiation of Part B will depend on the evaluation of safety, tolerability, and PK in Part A.
  2. Module 2: AZD0466 and voriconazole DDI study.

All participants will receive AZD0466, and administration will continue until disease progression, initiation of alternative anticancer therapy, unacceptable toxicity, withdrawal of consent, or other reasons to discontinue study treatment.

What is being measured

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

  1. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [Module 1]

    The safety and tolerability of AZD0466 in participants with advanced haematological malignancies were assessed.

    Measured: From screening (Day -28 to Day 1) up to 28 days after last dose (Approximately 2.1 years)

  2. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [Module 2]

    The safety and tolerability of AZD0466 in participants with advanced haematological malignancies were assessed.

    Measured: From screening (Day -28 to Day 1) up to 28 days after last dose (Approximately 2.1 years)

  3. Number of Participants With Dose-limiting Toxicity (DLT) [Module 1]

    The safety and tolerability of AZD0466 in participants with advanced haematological malignancies were assessed.

    Measured: upto 35 days

Secondary outcomes (7)
  1. Module 1: Complete Response Rate

    Complete response rate (CR+CRi) is defined as the percentage of participants who have a complete remission (CR) or incomplete haematological response (CRi).

    Measured: Day 1 until post treatment follow-up (28 days after last dose) (approximately 2.1 years)

  2. Module 1: Time to Response (TTR)

    Time to response is defined as the time from date of first dose until the date of first documented CR or CRi.

    Measured: Day 1 until post treatment follow-up (28 days after last dose) (Approximately 2.1 years)

  3. Module 1: Duration of Response

    Duration of Response (DoR) will be defined as the time from the date of first documented response (CR+CRi) until date of documented progression, relapse or failure or death due to any cause.

    Measured: Day 1 until post treatment follow-up (28 days after last dose) (approximately 2.1 years)

  4. Module 1: Overall Survival

    Overall survival (OS) is defined as time from date of first dose until the date of death due to any cause.

    Measured: Day 1 until post treatment follow-up (28 days after last dose) and survival follow-up (every month after last dose) (approximately 2.1 years)

  5. Module 2: Area Under the Plasma Concentration-curve (AUC) of AZD4320 After Administration of AZD0466 Alone and in Combination With Voriconazole

    Assessment of AUC to evaluate the drug-drug interaction potential between AZD0466 and the azole antifungal voriconazole.

    For this outcome measure, pharmacokinetics (PK) analysis set was included which consisted of all dosed participants with reportable plasma concentrations and no important AEs or protocol deviations that may affect PK.

    Measured: Cycle 1 Days 1, 2, 3, 4, 8 and days 15, 16, 17, 18, 19, and Cycle 2 Day 1, Cycle 3 Day 1 and beyond (Cycle length 28-days) (approximately 2.1 years)

  6. Module 2: Maximum Observed Plasma (Peak) Drug Concentration (Cmax) of AZD4320 After Administration of AZD0466 Alone and in Combination With Voriconazole

    Assessment of Cmax to evaluate the drug-drug interaction potential between AZD0466 and the azole antifungal voriconazole.

    For this outcome measure, PK analysis set was included which consisted of all dosed participants with reportable plasma concentrations and no important AEs or protocol deviations that may affect PK.

    Measured: Cycle 1: Days 1, 2, 3, 4, 8 and days 15, 16, 17, 18, 19, and Cycle 2 Day 1, Cycle 3 Day 1 and beyond (Cycle length 28-days) (approximately 2.1 years)

  7. Module 1 and Module 2: Plasma Concentration of AZD4320

    Assessment of AZD4320 to characterise the PK profile of AZD0466 following intravenous administration (via PK profiles of the active moiety AZD4320 in plasma).

    Measured: Module 1: Cycle 1 Days 1-30 (Cycle length 21 days) to Cycle 3 Days 1-28, & beyond (Cycle length 28 days); Module 2: Cycle 1 Days 1-8, Days 15-19 (Cycle length 21 days), Cycle 2 Day 1, Cycle 3 Day 1 & beyond (Cycle length 28-days) (approximately 2.1 Years)

What is this clinical trial studying?

A Phase 1 study testing AZD0466 and Voriconazole in people with Haematological Malignancies, run by AstraZeneca at 15 sites in 6 countries.

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 9 inclusion and 15 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 15 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States, Germany, Italy, Australia, France and 1 more country. 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 15 Jun 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 Adverse Events (AEs) and Serious Adverse Events (SAEs) [Module 1] (time frame: From screening (Day -28 to Day 1) up to 28 days after last dose (Approximately 2.1 years)). The study lists 3 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 15 Jun 2025.
