Testing AZD1775 as a Potential Targeted Treatment in Cancers With BRCA Genetic Changes (MATCH-Subprotocol Z1I)

July 29, 2026 updated by: National Cancer Institute (NCI)

MATCH Treatment Subprotocol Z1I: Phase II Study of AZD1775 in Patients With Tumors Containing BRCA1 and BRCA2 Mutations

This phase II MATCH treatment trial identifiesay block the protein tyrosine kinase WEE1 the effects of AZD1775 in patients whose cancer has a genetic change called BRCA mutation. AZD1775 may block a protein called WEE1, which may be needed for growth of cancer cells that express BRCA mutations. Researchers hope to learn if AZD1775 will shrink this type of cancer or stop its growth.

Detailed Description

PRIMARY OBJECTIVE:

I. To evaluate the proportion of patients with objective response (OR) to targeted study agent(s) in patients with advanced refractory cancers/lymphomas/multiple myeloma.

SECONDARY OBJECTIVES:

I. To evaluate the proportion of patients alive and progression free at 6 months of treatment with targeted study agent in patients with advanced refractory cancers/lymphomas/multiple myeloma.

II. To evaluate time until death or disease progression. III. To identify potential predictive biomarkers beyond the genomic alteration by which treatment is assigned or resistance mechanisms using additional genomic, ribonucleic acid (RNA), protein and imaging-based assessment platforms.

IV. To assess whether radiomic phenotypes obtained from pre-treatment imaging and changes from pre- through post-therapy imaging can predict objective response and progression free survival and to evaluate the association between pre-treatment radiomic phenotypes and targeted gene mutation patterns of tumor biopsy specimens.

OUTLINE:

Patients receive adavosertib (AZD1775) orally (PO) once daily (QD) on days 1-5 and 8-12 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3 months if less than 2 years from study entry, and then every 6 months for an additional year from study entry.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients must have met applicable eligibility criteria in the Master MATCH Protocol prior to registration to treatment subprotocol
  • Patients must have mutation in the BRCA1 or BRCA2 gene in the tumor, or another aberration, as determined via the MATCH Master Protocol. Patients with tumor carrying mutations defined as variants of uncertain significance will not qualify
  • Patients with ovarian cancer or HER2 negative, metastatic breast cancer must have received a PARP inhibitor as part of or as one of their prior lines of therapy
  • Patients must have an electrocardiogram (ECG) within 8 weeks prior to treatment assignment and must have no clinically important abnormalities in rhythm, conduction or morphology of resting ECG (e.g. complete left bundle branch block, third degree heart block)
  • Patients receiving any medications or substances that are inhibitors or inducers of CYP3A4, or CYP3A4 substrates need to be reviewed by the study investigator. Continuation of such medications will be at the discretion of the study investigator. Concomitant use of aprepitant and fosaprepitant is prohibited
  • Patients have hemoglobin (HgB) >= 9 g/dL, which should be done =< 4 weeks prior to registration to treatment step
  • Resting corrected QTc interval using the Fridericia formula (QTcF) should be < 450 msec/male and < 470 msec/female (as calculated per institutional standards) obtained from electrocardiogram (ECG), prior to enrollment. If resting QTc interval using the Fridericia formula (QTcF) is > 450 msec/male and > 470 msec/female (as calculated per institutional standards), then 2 additional ECGs should be performed 2-5 minutes apart at study entry. In order to be eligible, the mean resting corrected QTc interval using the Fridericia formula (QTcF) should be < 450 msec/male and < 470 msec/female (as calculated per institutional standards)

Exclusion Criteria:

  • Patients must not have known hypersensitivity to AZD1775 or compounds of similar chemical or biologic composition

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Objective response rate (ORR)
Time Frame: Up to 3 years

ORR is defined as the percentage of patients whose tumors have a complete or partial response to treatment among analyzable patients. Objective response is defined consistent with Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. 90% two-sided confidence interval is calculated for ORR. For the purposes of this study, patients should be re-evaluated for response:

  • For treatments given in 21 day (3 week) cycles: every 3 cycles (9 weeks) for the first 33 cycles, and every 4 cycles thereafter (12 weeks)
  • For treatments given in 28 day (4 week) cycles: every 2 cycles (8 weeks) for the first 26 cycles, and every three cycles thereafter (12 weeks)
  • For treatments given in 42 day (6 week) cycles: every 2 cycles (12 weeks)
Up to 3 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
6-month progression-free survival (PFS) rate
Time Frame: From start of treatment on that step until determination of disease progression or death from any cause, censored at the date of last disease assessment for patients who have not progressed, assessed at 6 months
Progression free survival is defined as time from treatment start date to date of progression or death from any cause, whichever occurs first. Disease progression was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Please refer to the protocol for detailed definitions of disease progression. 6 month PFS rate was estimated using the Kaplan-Meier method, which can provide a point estimate for any specific time point.
From start of treatment on that step until determination of disease progression or death from any cause, censored at the date of last disease assessment for patients who have not progressed, assessed at 6 months
Progression free survival (PFS)
Time Frame: From start of treatment on that step until determination of disease progression or death from any cause, censored at the date of last disease assessment for patients who have not progressed, assessed up to 3 years
PFS was defined as time from treatment start date to date of disease progression or death from any causes, whichever occurred first. Median PFS was estimated using the Kaplan-Meier method. Disease progression was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Please refer to the protocol for detailed definitions of disease progression.
