Updated on 29 December 2021


This is a modular, multicentre, open-label, non-randomised, Phase I/II, dose-setting and expansion study including an intra-participant ramp-up.

AZD4573 will be administered intravenously, in novel combinations with anti-cancer agents, to participants with relapsed/refractory haematological malignancies.


In Module 1 Part A (dose-setting), this study module will initially explore once weekly administration of AZD4573 at up to three target dose levels in combination with oral acalabrutinib 100 mg twice daily and will enroll participants with Diffuse large B-cell lymphoma (DLBCL), based on the observation of complete and partial responses amongst DLBCL patients treated with monotherapy. The primary objective of Part A will be to identify the maximum tolerated dose and/or Recommended Phase II dose (RP2D) for further evaluation in Part B.

In Module 1 Part B (expansion), separate expansion cohorts for participants with Germinal Centre B-cell (GCB) and non-GCB DLBCL subtypes will be opened at the RP2D.

Inclusion Criteria

Participant must be 18 years of age at the time of signing the informed consent
Participants with histologically confirmed, relapsed or refractory DLBCL, and where in the opinion of the investigator, a clinical trial is the best option for next treatment based on response and/or tolerability to prior lines of therapy. PART A
Diagnosis must be confirmed by biopsy and be immunohistologically characterized
Tumour tissue must also be available for sending to AstraZeneca for central cell of origin/pathology testing. PART B
Must have received standard of care first line therapy
Diagnosis must be confirmed by biopsy and be immunohistologically characterised
A newly obtained tumour biopsy is mandatory at screening to confirm cell of origin status and determine DLBCL subtype
Presence of radiographically measurable lymphadenopathy or extranodal lymphoid malignancy
Participants must have failed at least 2 prior therapies for the treatment of current disease, are not eligible for curative treatment options, and have no standard therapy available
Adequate haematologic function, without transfusion and growth factor support for
days before screening
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 Criteria
