This phase I/II study is trying to determine the appropriate dosing of a targeted therapy (AZD4573) alone, and then evaluate how effective it is when combined with another targeted therapy (acalabrutinib), in people with advanced blood cancersA Modular Phase I/II, Open-label, Multicentre Study to Assess AZD4573 in Novel Combinations With Anti-cancer Agents in Patients With Advanced Haematological Malignancies

Clinical summary

Summary

This is a non-randomised trial that has two modules, each with two parts. In Module 1 Part A, participants will receive ascending doses of AZD4573 (administered intravenously [via IV]) once weekly, in combination with oral, twice daily doses of acalabrutinib. Part A will have three different cohorts, each with different target dose levels of AZD4573. The primary objective of Part A is to determine the maximum tolerated dose for Part B. In Module 1 Part B, participants will receive AZD4573 at the dose level determined in Part A. Module 2 Part A has two phases. In Phase 1, participants will receive AZD4573 alone (administered via IV once weekly). In Phase 2, participants will receive AZD4573 (administered via IV once weekly) in combination with acalabrutinib (orally, twice daily). Module 2 Part B will be determined based on the data that emerges from Part A.

Conditions

This trial is treating patients with advanced blood cancers, including Diffuse large B-cell lymphoma, Marginal zone lymphoma, Germinal Centre B-cell lymphoma, non-GCB Diffuse large B-cell lymphoma and Mantle Cell Lymphoma

Eligibility

Inclusion

Inclusion Criteria - Core

  • Participant must be ≥ 18 years of age at the time of signing the informed consent.
  • Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2.
  • Must have received at least one prior line of therapy for the treatment of current disease and a clinical study is the best option for next treatment based on prior response and/or tolerability.
  • Documented active disease requiring treatment that is r/r defined as: Recurrence of disease after response to at least one prior line(s) of therapy or Progressive disease after completion of or on the treatment regimen preceding entry into the study or Disease that did not achieve an objective response (overall response of CR or PR).
  • Adequate haematological function.
  • Adequate organ function at Screening.
  • Uric acid level < upper limit of normal (ULN).

Inclusion Criteria - Module 1

- Participants with histologically confirmed, r/r DLBCL, or r/r MZL, for whom a clinical study is the best option for next treatment based on response and/or tolerability to prior lines of therapy.

PART A

• Participants with r/r DLBCL, including subtypes such as DLBCL not otherwise specified [NOS], high-grade B cell lymphoma [HGBCL], primary mediastinal large B-cell lymphoma [PMBCL], or large B cell lymphoma transformed from indolent B-cell lymphomas (including but not limited to Richter Syndrome, transformed Follicular Lymphoma, transformed MZL), or r/r MZL: participants with r/r MZL are eligible as well. In case fresh tumor biopsy is not available, archival tumor samples are acceptable, if done with 24 months

PART B • Participants with r/r de novo r/r DLBCL only, fresh tumor biopsy, done at screening or within 60 days before planned 1st dosing, unless there was any anticancer treatment given after tumor biopsy, but prior initiated study treatment.

  • Presence of radiographically measurable lymphadenopathy or extranodal lymphoid malignancy.
  • Participants must have failed at least two prior therapies for the treatment of current disease. Participants shall not be eligible for curative treatment options, and have no standard therapy available (including CAR-T cell therapy).
  • Adequate haematologic function at screening: No growth factor support within 14 days prior to the date of the screening laboratory assessment; No transfusions within 7 days prior to the date of the screening laboratory assessment.
  • Optional tumour biopsy on study: Participants are also encouraged to consent to and undergo an optional tumour biopsy at disease progression to support correlative biomarker studies.
  • All participants must be willing and able to provide mandatory baseline bone marrow biopsy/aspirate.

Inclusion Criteria - Module 2

- Participants with histologically confirmed r/r MCL for whom a clinical study is the best option (in the opinion of the investigator) for next treatment based on response and/or tolerability to prior lines of therapy.

PART A

  • Participants with r/r MCL:

    • Diagnosis must be confirmed by biopsy and be immunohistologically characterised.
    • Tumour tissue must also be available for sending to AstraZeneca for pathology testing.
  • Presence of radiographically measurable lymphadenopathy or extranodal lymphoid malignancy
  • Participants must have failed at least one prior therapy for the treatment of current disease and not be eligible for treatment with curative intent (e.g. allogenichaematopoietic cell transplantation [HCT]). Eligible participants include both BTKi-naïve and BTKi-exposed.
  • Adequate haematologic function at screening: No growth factor support within 14 days prior to the date of the screening laboratory assessment; No transfusions within 7 days prior to the date of the screening laboratory assessment.
  • Optional tumour biopsy on study: Participants are also encouraged to consent to and undergo an optional tumour biopsy at disease progression to support correlative biomarker studies.
  • All participants must be willing and able to provide mandatory baseline bone marrow biopsy/aspirate.

Exclusion
